  • [Title] Complete unilateral maxillary sinus opacity in computed tomography.
  • BACKGROUND/PURPOSE: Unilateral maxillary sinus opacity can be caused by many diseases, but an exact diagnosis is difficult to make.
  • The aim of this study was to describe the pathological conditions and clinical features of patients with unilateral maxillary sinus opacity.
  • METHODS: From 2004 to 2008, 830 consecutive patients underwent sinus surgery or endonasal endoscopic biopsy at an academic tertiary care center.
  • The preoperative computed tomography (CT) images for these patients were reviewed, and 11 6 patients were identified with complete unilateral maxillary sinus opacification.
  • RESULTS: The most frequent diagnoses were as follows: chronic rhinosinusitis (52.6%), fungus ball (29.3%), antrochoanal polyp (2.6%), benign tumor (10.4%), and malignancy (5.1%).
  • Fungus ball was the most common diagnosis (10/18, 55.6%) in the subgroup of patients with isolated maxillary sinus opacity without disease in the other sinuses.
  • Erosion of the maxillary posterolateral wall and extra-sinus extension suggested malignancy.
  • CONCLUSION: Although unilateral maxillary sinus opacity is usually inflammatory in origin, fungal sinusitis and neoplastic disorder are also likely.
  • A careful history-taking, a thorough head and neck examination including nasal endoscopy, and CT evaluation are all imperative for reaching a correct diagnosis.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Respiratory epithelial adenomatoid hamartoma of the maxillary sinus: case report.
  • The case is described of a male patient with respiratory epithelial adenomatoid hamartoma of the left maxillary sinus that initially presented as a chronic sinus inflammation.
  • This benign lesion is characterized by glandular proliferation originating from the surface of the respiratory epithelium.
  • Maxillary sinus localisation is very rare but is very important to be able to distinguish hamartomas from schneiderian papillomas of the inverted type and adenocarcinomas, potentially requiring aggressive surgical treatment.
  • Moreover, misinterpretation of the respiratory epithelial adenomatoid hamartoma as chronic sinus inflammation may result in inadequate treatment.

  • [Title] Benign pleomorphic adenoma of the soft palate metastasizing to the sphenoid sinus.
  • A benign pleomorphic adenoma is the most common tumor of the salivary glands.
  • This tumor has the potential to metastasize to bone, the head and neck region, visceral organs and skin.
  • Although there a few reports about a benign pleomorphic adenoma metastasizing to the maxillary sinus in the paranasal sinuses, there are no reports about a metastatic benign pleomorphic adenoma in the sphenoid sinus.
  • We report here on a case of a benign pleomorphic adenoma of the soft palate that metastasized to the sphenoid sinus, and we briefly review the relevant clinical literature.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Ossifying fibroma of the maxillary sinus at the Kara (Togo) Teaching Hospital.
  • INTRODUCTION: Ossifying fibroma of the jaw is a benign tumorous disease, somewhat rare and aggressive.
  • It frequently targets the mandible, but seldom the maxillary.
  • CASE STUDY: The present study reports the first case of left maxillary sinus fibroma treated at the Kara Teaching Hospital in North Togo.
  • It occurred in a 29-year-old patient who experienced slow-growing tumefaction of the left maxillary sinus, resulting in deformation of the left side of the face in the maxillary region and ipsilateral nasal obstruction.
  • The CT scan of the nose and sinuses revealed a tumorous lesion of expanding bony density increasing in volume at the outer wall of the left maxillary sinus, of regular shape that contained microscopic calcifications, extending into the ipsilateral orbital floor and pushing the surrounding soft tissues forward without invading them.
  • The histopathological examination of the tumor confirmed the diagnosis of ossifying fibroma.
  • DISCUSSION: Ossifying fibroma or fibrous osteoma is a rare and benign lesion developing insidiously with a polymorphous aspect.
  • However, only examination of the gross specimen can provide the final diagnosis.

  • The calcifying epithelial odontogenic tumor is a benign epithelial odontogenic lesion that accounts for less than 1% of all odontogenic tumors.
  • Extension of this lesion to the maxillary sinus is extremely rare.
  • This tumor was encased between the right maxillary lateral and canine roots with extension to the maxillary sinus.
  • Histologically, the tumor is composed of sheets of epithelial cells with eosinophilic or clear cytoplasm, intercellular bridges, nuclear pleomorphism, but no mitotic figures, amorphous eosinophilic and calcified materials were seen within the sheets of epithelial cells.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] [Endoscopic medial maxillectomy for maxillary sinus tumors: indications and clinical outcome].
  • Endoscopic sinus surgery (ESS) widely conducted in nasal and paranasal sinus surgery provides superior magnification, illumination, and angled visualization, enabling the surgeon to isolate the tumor base and accurately define disease extent.
  • Endoscopic medial maxillectomy (EMM), an advanced ESS procedure, effectively treats benign sinonasal neoplasms such as inverted papilloma.
  • We analyzed a series of EMM cases and their clinical outcomes, including 9 inverted papillomas, 1 solitary fibrous tumor, 1 hemangioma, 1 blood boil and 1 esthesioneuroblastoma.
  • Removal of the medial wall and the wide maxillary sinus opening enabled by EMM allows easy access to the entire maxillary sinus with a generous work space.
  • We found EMM to be safe and efficacious in resecting maxillary sinus tumors thanks to its improved accessibility and visualization.
  • In conclusion, EMM enables complete removal of benign tumors from the maxillary sinus, having the advantages of no external incision, decreased blood loss, low morbidity, shorter hospital stay, and the possibility of repetition in recurrence, compared to conventional approaches.
  • EMM may thus become the treatment of choice for maxillary sinus tumors.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Contralateral maxillary sinus lesions in patients with nasal cavity and/or paranasal sinus carcinoma: analysis of computed tomography findings.
  • OBJECTIVES: The incidence of bilateral maxillary sinus carcinoma is very low in patients with primary maxillary sinus carcinoma.
  • However, surgeons should perform careful diagnosis of any contralateral maxillary sinus lesions to avoid missing a second primary maxillary sinus carcinoma.
  • We therefore investigated the computed tomography (CT) findings of the contralateral maxillary sinus in patients with nasal cavity and/or paranasal sinus carcinoma.
  • METHODS: Between August 1994 and September 2006, 66 patients (41 male, 25 female; age range, 22 to 85 years; mean age, 56.9 years) with nasal and/or paranasal sinus carcinoma were treated.
  • Preoperative and follow-up CT scans of their contralateral maxillary sinuses were retrospectively reviewed.
  • Twenty-three of the 32 patients with benign lesions were included in the follow-up CT analysis, ranging from 24 to 108 months (mean, 45 months).
  • During the follow-up period, no definite abnormality suggesting tumor development in the contralateral maxillary sinus was detected.
  • CONCLUSIONS: Even though most contralateral maxillary sinus lesions are benign and the incidence of bilateral maxillary sinus carcinoma is very low, second primary maxillary sinus carcinoma should be kept in mind in the differential diagnosis of contralateral maxillary sinus lesions in patients with nasal cavity and/or paranasal sinus carcinoma.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Preoperative washing cytology in the diagnosis of maxillary sinus lesions.
  • OBJECTIVE: To assess the preoperative value of washing cytology in maxillary sinus lesions with suspected malignancy.
  • STUDY DESIGN: Over a 4-year period, 96 p tients with clinical or radiologic suspicion of a malignant maxillary sinus tumor either confined to the maxillary complex or extending to the nasal cavity underwent preoperative cytologic evaluation by sinus puncture and local washing or nasal washing.
  • Subsequently all patients underwent endoscopic sinus surgery (ESS) and partial or total maxillectomy.
  • RESULTS: There were 47 malignant, 42 benign and 7 borderline cases.
  • Benign lesions included inflammatory conditions (17), squamous proliferations (6), soft tissue lesions (9) and odontogenic lesions (10).
  • Diagnostic agreement between cytology and follow-up biopsy was seen mostly in benign inflammatory and odontogenic lesions and in squamous cell carcinoma and salivary gland malignancies.
  • CONCLUSION: Preoperative sinus washing cytology is a noninvasive and rapid method of diagnosis, with a definite impact on patient surgical planning.
  • Clusters of sloughed epithelial cells, so called Creola bodies, may be a diagnostic pitfall in benign lesions.

  • [Title] [Correlation of GST-pi and PCNA expression to prognosis of advanced maxillary sinus squamous cell carcinoma].
  • BACKGROUND & OBJECTIVE: Tumor markers which relate to cell proliferation and metabolism have seldom been studied in maxillary sinus cancer.
  • This study was conducted to identify the correlation of glutathione S-transferase pi (GST-pi) and proliferating cell nuclear antigen (PCNA) expression to prognosis of advanced maxillary sinus squamous cell carcinoma (SCC).
  • METHODS: The expression of GST-pi and PCNA in 54 specimens of maxillary sinus SCC, 29 specimens of benign maxillary tumor, and 20 specimens of normal nasal mucosa was detected by immunohistochemistry.
  • The correlation of GST-pi and PCNA expression to prognosis of advanced maxillary sinus SCC was analyzed by Kaplan-Meier method.
  • RESULTS: The overexpression rates of GST-pi and PCNA were significantly higher in maxillary sinus SCC than in benign maxillary tumor and normal nasal mucosa (74.1% vs. 89.6% and 15.0%, P<0.01; 79.6% vs. 3.4% and 0, P<0.01).
  • The 5-year survival rate was significantly higher in advanced maxillary sinus SCC patients with high expression of GST-pi than in the patients with low expression of GST-pi (34.5% vs. 21.2%, P=0.025); the difference between the patients with high and low expression of PCNA was not significant (18.0% vs. 27.0%, P=0.890).
  • The expression of GST-pi was an independent prognostic factor of advanced maxillary sinus SCC (P=0.039, odds ratio>1).
  • CONCLUSION: The overexpression of GST-pi is an independent prognostic factor of advanced maxillary sinus SCC, but that of PCNA isn't.

  • [Title] [Endoscopic resection of benign and malignant tumors in the nasal cavity and paranasal sinus].
  • Endoscopic resection of nasal and paranasal sinus tumors is more aesthetic and less invasive than conventional resection, such as Luc's operation and lateral rhinotomy.
  • We clarified the effect of radical endoscopic tumor excision and the control of local bleeding hazardous in endoscopic surgery.
  • Subjects were patients with benign lesions in the nasal cavity, medial wall of the maxillary sinus, ethmoid sinus, and/or sphenoid sinus without concurrent malignant lesions.
  • Although patients selection for malignant tumor excision was based on (1) possible en bloc resection, (2) low-grade malignant tumors, and (3) tumors in the nasal cavity and adjoining paranasal sinus, the final decision was made individual.
  • Subjects were 23 patients with benign tumor (10 inverted papilloma, 9 hemangioma, 2 juvenile angiofibroma, and 2 other tumors) and 4 with malignant tumor (olfactory neuroblastoma, acinic cell carcinoma, squamous cell carcinoma, and chondroid chordoma) in the nasal and paranasal sinus.
  • The tumor was resected en bloc except for patients with inverted papilloma (2 cases) and chondroid chordoma.
  • Recurrence in benign tumors was zero during a mean observation of 21 months.
  • The endoscopic excision of benign lesions in the nasal and paranasal sinus is thus as effective as conventional radical surgery.

  • [Title] Pindborg tumor in children.
  • Pindborg tumor or calcifying epithelial odontogenic tumor is a rare benign neoplasm.
  • The average age at diagnosis is 40 years without a significant prevalence for one sex.
  • The most frequent localization is the mandibular premolar and molar area; less frequently the lesion is found in the maxilla, while other localizations like the maxillary sinus are extremely rare.
  • The authors report a peculiar case of Pindborg tumor characterized by a rare localization of the lesion (maxillary incisal area) and by the young age of the patient (nine years old).
  • The purpose of the surgical treatment is the radical resection of the neoplasm with clean margins in order to reduce the risk of recurrence of disease.

  • The patient had a history of orbital meningioma from 10 years ago and several surgical resections due to tumor recurrence during these 10 years.
  • MRI images revealed a large left orbital mass with optic nerve involvement and extension to the left maxillary sinus, pterygoid fossa and the dura in the floor of the anterior fossa.
  • Fine-needle aspiration cytology of the mass confirmed tumor recurrence.
  • The patient first received radiotherapy due to the inoperable mass, and the tumor was resected 1.5 month later.
  • The interesting aspect of this case was the aggressive behavior of the tumor with intraocular invasion, despite its benign histopathological features, which led to wide exenteration of the eye together with resection of the upper and lower lids.

  • [Title] Modified surgical approach for removal of an ivory osteoma in the paranasal sinus. A case report.
  • Osteomas are benign tumors that consist mainly of mature compact or cancellous bone.
  • The most common site in maxillofacial complex is the mandible, particularly the angle, followed by sinuses.
  • The authors report a case of an ivory osteoma of the paranasal sinus in a 16 year-old male patient.
  • The lesion was located in the left paranasal sinus (frontal, ethmoidal and maxillary), obstructing the nasolacrimal duct, resulting in dacryocystitis and frontal mucocele.
  • The ethmoid and orbital portions were approached and excised through a Weber-Ferguson incision and maxillary osteotomy was carried out to remove the ivory osteoma, considering its location in the central and deep region of the face.
  • After tumor removal and drainage of frontal and ethmoidal sinuses, the bone flap was repositioned using titanium microplates and screws.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] [Investigation of the surgical approach for resecting infratemporal fossa pterygomaxillary fossa-parapharyngeal space tumor].
  • OBJECTIVE: To investigate the optimal surgical approach for resecting infratemporal fossa-pterygomaxillary fossa-parapharyngeal space tumor.
  • METHOD: Sixty-six patients with infratemporal fossa-pterygomaxillary fossa-parapharyngeal space tumor were analyzed retrospectively from 1998-2004, including complains, symptoms, physical signs; histodiagnosis, image examinations and surgical approaches.
  • RESULT: No recurrence was found in fifty benign tumor cases after 2 to 5 years, while in 16 cases with malignant tumor, four patients died in one year, 8 cases died in 2 to 4 years, and only 4 patients' survival time exceeded 4 years.
  • CONCLUSION: Extended maxillectomy is suitable for resecting primary carcinoma of maxillary sinus invading pterygomaxillary fossa, infratemporal fossa and /or parapharyngeal space tumor. also midface degloving approach is suitable for nasal primary cavity, nasal sinuses, nasopharynx and/or pterygomaxillary fossa tumor and localized malignant tumor.
  • Trans-cervical combining mandibular split swing approach is suitable for parapharyngeal space tumor invading pterygomaxillary fossa and/or infratemporal fossa tumor.
  • Trans-cervical jaw combining mandibulotomy is suitable for resecting parapharyngeal space, infratemporal fossa tumor for invading lateral skull base and pterygomaxillary fossa tumor.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • BACKGROUND: Regardless of advances in diagnosis and treatment during the past 40 years, the overall 5-year survival rates for oral and oropharyngeal squamous cancers have only slightly improved and remain around 50%.
  • Thus, the early diagnosis and treatment of carcinoma by health care providers are essential in achieving a good prognosis.
  • We report a case of invasive squamous cell carcinoma that presented as a benign endodontic-periodontic lesion with a 7-mm periodontal pocket on tooth #15 in a 40-year-old, non-smoking woman.
  • A periodontal flap surgical procedure was performed on teeth #13 to #15, and as there was bone erosion into the maxillary sinus, a biopsy of the soft tissue was submitted to the local hospital for histological analysis.
  • The treatment of the carcinoma involved a hemimaxillectomy with the removal of the maxillary left posterior teeth.
  • The patient remained free of tumor for 5 years after the initial presentation.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • PURPOSE: A clinico-pathologic study of typical symptoms of intra- and extraoral angiosarcomas and clinical course under therapy is presented as well as an analysis of the immunohistochemical differential diagnosis of the tumour specific formed spaces.
  • PATIENTS AND METHODS: Four male patients aged 63-78 years suffered from angiosarcomas of the maxillary sinus, the bucca (two patients) and the alveolar ridge of the lower jaw.
  • RESULTS: While the benign appearance of the lesions resulted primarily in wrong diagnoses the histopathologic examination of the biopsies revealed the characteristic pattern of angiosarcomas.
  • Wide surgical excision, radiotherapy and/or antiangiogenic chemotherapy could not prevent tumour progression and death within two and a half years after primary diagnosis.
  • The tumour associated structural defect of vascular lamina with partial loss of pericytes/vascular smooth muscle cells was identified immunohistochemically by alpha-smooth-muscle-actin and for the first time by tenascin-C.
  • ) The variable presentation and the benign appearance of oral and perioral angiosarcomas may often delay diagnosis.

  • INTRODUCTION: Inverted papilloma (IP) is a benign but locally aggressive sinonasal tumor.
  • Those localized to the maxillary sinus or medial maxillary wall have classically been removed through an external approach.
  • Successful endoscopic management is based on accurate intraoperative identification and complete resection of the tumor.
  • MATERIALS AND METHODS: A prospective study of patients with maxillary sinus IP treated with endoscopic or endoscopic-assisted resection over a 12-month period was conducted.
  • Intraoperatively, the site of tumor attachment was identified, and a 1- to 2-cm wedge of bone with overlying tumor was removed en bloc and analyzed under light microscopy.
  • Preoperative radiographic studies were analyzed with respect to bony changes in the area of the tumor pedicle.
  • Radiographic osteitic bony changes were seen at site of tumor attachment in 100% of cases.
  • CONCLUSION: The irregularity of the bony surface may hinder complete tumor removal because microscopic rests of mucosa can be hidden within the bony crevices.
  • Intraoperative removal of the bony surface at the site of tumor attachment may ensure a more complete removal.

  • In one patient the estimation of primary tumor localization was not possible, because of the very large extension of the neoplasm.
  • The choice of the surgical procedure was depend on the tumor extension and localization.
  • In 8 other patients upper maxillary resection were done.
  • In two cases the total maxillectomy were performed, in the next two lower maxillary resection.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • INTRODUCTION: Chondromas are uncommon benign tumors of cartilaginous origin.
  • A chondroma is a painless, slow growing tumor causing destruction and exfoliation of teeth.
  • On a radiograph, the tumor appears as a cyst-like radiolucent lesion, while some are sclerotic.
  • DISCUSSION AND CONCLUSION: Chondromyxoid fibroma (CMF) is a rare, benign cartilaginous tumor that often occurs in the metaphyses of proximal tibia, proximal and distal femur and small bones of the foot.
  • The differential diagnosis is wide and includes simple or aneyrismal bone cyst, giant cell tumor, nonossifying fibroma, fibrous dysplasia, enchondroma, chondroblastoma, eosinophilic granuloma and fibrous cortical defect.
  • Our case demonstrates an uncommon occurrence in the maxillary sinus: CMF with nasal, pterygoid and orbital infiltration.
  • In the diagnosis of an intracranial chondrocytic tumor, it is important to distinguish it from enchondroma and chondrosarcoma.
  • The present case underlines the importance of MR examination in the diagnosis of soft tissue masses in the craniofacial region.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • BACKGROUND: Osteomas are relatively common, benign, slow-growing, often asymptomatic neoplasms of the paranasal sinuses occurring mainly in the frontal and ethmoid sinuses.
  • Surgical removal is done if they extend beyond the boundaries of the sinus, continue to enlarge, are localized in the region adjacent to the nasofrontal duct, or if signs of chronic sinusitis are present and, regardless of size, in symptomatic tumors.
  • Most commonly involved was the frontal sinus (11 cases, including a giant tumor comprising both frontal sinuses and 2 osteomas penetrating to the orbit), followed by ethmoid cells (3) and maxillary sinuses (2).
  • RESULTS: One osteoma was diagnosed in the sphenoid sinus.
  • Eight open procedures were performed to remove frontal and maxillary osteomas, five tumors were removed under endoscopic guidance, and four via combined procedures.
  • Giant frontal sinus osteomas can be effectively approached by a combined external and endoscopic procedure.
  • Obliteration of the sinus is not mandatory if the mucous membrane is intact.

  • Partial or total maxillary swing combined with naso pyramid translocation in 13 cases.
  • RESULT: Of the 27 malignant cases the 3 and 5-year survival rates were 81.9% (22/27) and 62.9% (17/27) respectively, and one tumor free case living well more than 9 years.
  • There were no recurrence in 10 cases with benign tumor.
  • CONCLUSIONS: Various craniofacial approaches except lateral rhinotomy provide directly satisfactory tumor exposure and facilitate enbloc resection of the naso paranasal sinus tumor with intracranial extension.
  • Partial or total maxillary swing combined with naso pyramid translocation is good for tumor involving the skull base without intracranial invasion.
  • The fronto-nasal pyramid translocation is good for removal of the upper part of nasal tumor with intracranial extension on well developed frontal sinus.
  • The fronto orbital approach is proper for removal of fronto-sphenoid tumor and midface degloving may be used in selected cases.

  • JNA (Juvenile nasopharyngeal angiofibroma) is a benign but highly vascular and aggressive tumor that takes its origin in the basisphenoid region close to the sphenopalatine foramen.
  • Nowadays endonasal endoscopic approach is performed by experienced teams even for extended tumor.
  • This case confirms the necessity of a long follow-up for all the patients who had a transantral surgery with resection of the medial wall of the maxillary sinus and dissection of the nasolacrymal duct.
