  • [Title] [Unilateral benign choanal polyp: review of 51 patients].
  • [Transliterated title] Pólipo coanal unilateral benigno: revisión de 51 pacientes.
  • INTRODUCTION: Choanal polyps are a benign pathology arising in the sinusal mucosa and entering the nasal fossa heading for the choana.
  • It must be surgically removed, with exeresis of both the nasal and the sinusal lesions.
  • MATERIAL AND METHOD: A retrospective review has been made of 51 patients treated for choanal polyp at our centre.
  • They were diagnosed through physical examination, nasal endoscopy, nasosinusal CT, and histological examination of biopsy from the mass in selected cases.
  • RESULTS: The choanal polyps originated in the maxillary sinus in 46 cases, in the ethmoidal sinus of 5 patients, and only 1 in the sphenoid sinus.
  • Antrochoanal and ethmoidochoanal polyps were simultaneously found in 1 patient.
  • Unilateral nasal obstruction was the main clinical presentation in our series.
  • Nasal discharge, epistaxis, and snoring were other initial clinical findings.
  • Eighty-five per cent (39/46) of antrochoanal polyps (ACP) emerged into the nasal fossa through Giraldés's accessory orifice, and 15% (7/46) through the natural ostium of the sinus.
  • Other options employed were the Caldwell-Luc approach and a combination of limited antrostomy and endoscopic nasal surgery; these were among the first cases seen and therefore the oldest.

2. Frosini P, Picarella G, De Campora E: Antrochoanal polyp: analysis of 200 cases. Acta Otorhinolaryngol Ital; 2009 Feb;29(1):21-6

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Antrochoanal polyp: analysis of 200 cases.
  • Antrochoanal polyp was described by Professor Gustav Killian, in 1906, giving a specificity among polyposis; it represents 4-6% of all nasal polyps and displays both analogies and differences with bilateral nasal polyposis.
  • Antrochoanal polyp is a benign lesion originating from the mucosa of the maxillary sinus, growing through the accessory ostium into the middle meatus and, thereafter, protruding posteriorly to the choana and nasopharynx.
  • Incomplete excision of antrochoanal polyp almost always leads to recurrence.
  • Whether the antrochoanal polyp is a benign tumour or not?
  • The Authors analyse the largest series of antrochoanal polyps present in the literature and report on a series of 200 patients treated consecutively at the ENT Clinic at the University of Florence, Italy.
  • In conclusion, based on the data obtained, it is tempting to suggest that the antrochoanal polyp develops from an increase in pressure in the Highmoro antrum due to a phlogistic-anatomical alteration at ostio-meatal complex/middle meatus level, in patients with a pre-existing silent antral cyst, subsequently forced to herniation outside, through the accessory ostium.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Evaluation and management of antrochoanal polyps.
  • Antrochoanal polyps (ACPs) are benign polypoid lesions arising from the maxillary antrum and they extend into the choana.
  • Nasal obstruction and nasal drainage are the most common presenting symptoms.
  • The differential diagnosis should include the causes of unilateral nasal obstruction.
  • Nasal endoscopy and computed tomography scans are the main diagnostic techniques, and the treatment of ACPs is always surgical.
  • Physicians should focus on detecting the exact origin and extent of the polyp to prevent recurrence.

  • [Title] Nasal mass mimicking antrochoanal polyp.
  • Sphenochoanal polyp is a rare form of choanal polyp.
  • As the name suggests, it originates from the sphenoid sinus and extends down the choana and nasopharynx.
  • If wrongly diagnosed as an antrochoanal polyp, it can lead to unnecessary exploration of the maxillary sinus and incomplete removal of the sphenoid component of polyp.
  • Here we report a case of 40-year-old woman who presented with history of progressive left nasal obstruction and mass in the oropharynx.
  • A diagnosis of sphenochoanal polyp was made on the basis of nasal endoscopy and computed tomography scan.
  • The polyp was removed endoscopically.

  • [Title] Superantigens and chronic rhinosinusitis: skewing of T-cell receptor V beta-distributions in polyp-derived CD4+ and CD8+ T cells.
  • BACKGROUND: Recent studies have suggested that Staphylococcus aureus secrete superantigenic toxins that play a role in the etiology of chronic rhinosinusitis with nasal polyposis (CRSwNP).
  • The aim of this study was to analyze the pattern of V beta-expression in polyp-derived lymphocytes from CRSwNP patients.
  • METHODS: Polyps were harvested from 20 patients with CRSwNP and 3 patients with antrochoanal polyps.
  • Flow cytometry was used to analyze the V beta-repertoire of polyp-derived CD4+ and CD8+ lymphocytes.
  • The three antrochoanal polyps failed to show any significant V beta-skewing.
  • CONCLUSION: This study establishes evidence of S. aureus SAg-T-cell interactions in polyp lymphocytes of 35% of CRSwNP patients.
  • Although these results are consistent with intranasal exposure of polyp lymphocytes to SAg's, additional study is necessary to establish the role of these toxins in disease pathogenesis.

  • OBJECTIVES: We evaluated the results of endoscopic treatment for choanal polyps.
  • PATIENTS AND METHODS: Twelve patients (5 females, 7 males; mean age 25 years; range 10 to 49 years) underwent endoscopic surgery for choanal polyps.
  • Preoperatively, all the patients were evaluated with endoscopic nasal cavity and nasopharyngeal examination and computed tomography of the paranasal sinuses.
  • There were seven antrochoanal (58%), two ethmochoanal (17%), two sphenochoanal polyps, and one patient (8%) had a chonchachoanal polyp.
  • Anterior ethmoidectomy and intranasal polypectomy were performed for ethmochoanal and sphenochoanal polyps, respectively.
  • In all the patients, the mucosa giving rise to polyps was removed.
  • RESULTS: The most common symptoms were nasal obstruction (70%) and nasal discharge (52%).
  • Allergic tests were positive in two patients with antrochoanal polyps.
  • CONCLUSION: Endoscopic approach for choanal polyps can be applied at all ages and it is associated with low morbidity.

13. Sayed RH, Abu-Dief EE: Does antrochoanal polyp present with epistaxis? J Laryngol Otol; 2010 May;124(5):505-9

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Does antrochoanal polyp present with epistaxis?
  • OBJECTIVE: To compare the gross and microscopic appearance of antrochoanal polyps associated with recurrent epistaxis, with those with a more typical presentation.
  • METHODS: All patients underwent clinical and endoscopic examination, computed tomography scanning, and examination under anaesthesia, in order to detect the gross diagnostic criteria for antrochoanal polyp.
  • Histological findings on light microscopy were compared for polyps presenting with epistaxis versus those without.
  • RESULTS: Recurrent epistaxis was a presenting symptom in 10/84 (11.9 per cent) patients with gross diagnostic criteria for antrochoanal polyp.
  • Grossly, these patients' polyps had a reddish, vascular surface in parts.
  • Histologically, these polyps showed a highly vascular stroma with multiple dilated blood vessels, the typical appearance of an angiomatous antrochoanal polyp.
  • The remaining cases (88.1 per cent) had no history of epistaxis; histologically, these patients' polyps showed an oedematous connective tissue core with few inflammatory cells.
  • Plasma cells were predominant in the angiomatous polyps, being significantly more prevalent than in the ordinary antrochoanal polyps (p < 0.00).
  • CONCLUSIONS: It would appear that only angiomatous antrochoanal polyps present with epistaxis.
  • Detection of the characteristic gross appearance of these polyps may help avoid unwanted surgery.
  • A significantly increased number of plasma cells may be the underlying cause of the histological changes seen in angiomatous antrochoanal polyps.

  • We present the first reported case of simultaneously occurring bilateral antrochoanal polyps in a 49-year-old female patient, originated from previously performed inferior antrostomies as a treatment for chronic maxillary sinusitis.
  • The antrochoanal polyps were removed by endoscopic surgery with combined approach through the inferior and middle meatal antrostomies.
  • Microscopic analysis of the specimens showed benign inflammatory antrochoanal polyps.
  • Endoscopic treatment with middle meatal antrostomy is the recommended technique in most cases of antrochoanal polyps as the greater portion of the antral part of the polyp can be removed with the healthy antral mucosa left intact promoting epithelialization and mucociliary clearance of the antrum.

  • [Title] Assessment of nasal obstruction with flexible nasal endoscopy.
  • OBJECTIVE: To report the value of nasal endoscopy as an outpatient procedure in the diagnosis of posterior nasal obstruction.
  • METHODS: Over one year period, from March 2002 to March 2003, we evaluated 130 adult patients that attended the Ear, Nose and Throat Department of Sohag University Hospital in Egypt with persistent nasal obstruction via anterior rhinoscopy and flexible nasopharyngoscopy.
  • RESULTS: Forty-six percent of our cases had posterior nasal obstruction, 43.5% due to post-choanal lesions (mainly adenoid), 33% due to pre-choanal lesions (mainly choanal polyps), and 23.5% due to choanal lesions (mainly choanal adenoid).
  • CONCLUSION: We conclude that flexible nasal endoscopy is superior to visual examination in the evaluation of nasal obstruction; hence, we recommend its routine use.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • The main presenting symptoms are nasal blockage 97.4% and rhinorrhea 94.7%.
  • The commonest clinical diagnoses were simple nasal polyp 47(61.8%) and antrochoanal polyp 10(13.2%).
  • The commonest histological diagnosis is simple inflammatory nasal polyp in 28 (36.8%) patients and the least was nasal capillary hemangioma 2 (2.6%).
  • CONCLUSIONS: Nasal obstruction and rhinorrhea are the commonest symptoms of presentation, simple inflammatory nasal polyp is still the commonest histological pattern seen in our environment, and surgery is still the best modality of treatment for benign tumor thus the need for advocacy for early recognition and referral to the ENT surgeon.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Isolated sphenochoanal polyp: A rare clinical entity.
  • Choanal polyps almost always appear as solitary growth and most commonly arise from the maxillary sinus.
  • Isolated polyp originating from the anterior wall of the sphenoid sinus or from its interior and extending as choanal polyp in to the nasopharynx are extremely rare clinical entities.
  • Here we report a 34-year-old male presenting with a history of headache, intermittent nasal discharge and nasal obstruction.
  • A diagnosis of sphenochoanal polyp (SCP) was made on nasal endoscopy and magnetic resonance imaging.
  • The SCP was removed endoscopically via a transnasal sphenoidotomy and histopathologically it was confirmed as inflammatory polyp.

42. Chen HJ, Chen HS, Chang YL, Huang YC: Complete unilateral maxillary sinus opacity in computed tomography. J Formos Med Assoc; 2010 Oct;109(10):709-15

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • 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%).
  • Nasal discharge and foul-smelling breath were more common in inflammatory disease than in neoplastic disease.
  • Neoplastic disease was more likely to present as epistaxis; a polyp or mass revealed by nasal endoscopy; mass effect in the cheek, palate, or gingiva; and bony erosion on CT.
  • 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.

  • CONCLUSION: Inferior turbinate enlargement (ITE), nasal valve collapse (NVC) and concha bullosa (CB) are nasal anatomic problems that may accompany septal deviation (SD).
  • In patients complaining of nasal obstruction, all nasal structures that may contribute to the symptom must be separately and carefully assessed for setting an appropriate treatment plan and thereby minimizing the failure rate of surgery.
  • Patients with other forms of SD, allergic rhinitis, non-allergic rhinitis with eosinophilia, acute and chronic sinusitis, nasal polyposis, antrochoanal polyps, those who had recently used systemic or topical decongestants and patients with a history of previous nasal surgery were excluded from the study group.

  • OBJECTIVE/HYPOTHESIS: The role of infectious agents in the etiology of chronic rhinosinusitis with nasal polyposis (CRSwNP) remains unclear.
  • Recent studies have provided indirect evidence of exposure to staphylococcal exotoxins in the blood and polyp tissue of patients with CRSwNP.
  • The objective of the study was to analyze mucus and polyp tissue samples from patients with CRSwNP for the presence of staphylococcal exotoxins.
  • Twenty-nine of 42 patients had chronic rhinosinusitis with bilateral nasal polyposis, 2 had antrochoanal polyps, and 11 had chronic rhinosinusitis without nasal polyps.
  • Eleven patients without chronic rhinosinusitis or polyps served as normal control patients.
  • RESULTS: At least one toxin was detected in 14 of 29 patients with bilateral nasal polyposis.
  • Mean eosinophil counts tended to be higher in ELISA-positive patients with polyps compared with patients without toxin detection.
  • Only 1 of the 13 patients with CRS without polyps had positive ELISA results for toxin.
  • Further studies are necessary to correlate the presence of toxin with the pathological changes present in polyp tissue.

  • [Title] Sphenochoanal polyp presenting with concomitant nasal polyps.
  • A sphenochoanal polyp is a rare lesion that originates in the sphenoid sinus.
  • We present what to the best of our knowledge is the first reported case of a sphenochoanal polyp associated with concomitant nasal polyps.
  • The patient was a 54-year-old man who presented with bilateral nasal obstruction, possible obstructive sleep apnea, and an altered voice, all of which had likely been caused by the presence of a massive left sphenochoanal polyp and bilateral grade III anterior and posterior ethmoid polyps.
  • Therefore, the polyps were removed endoscopically under local anesthesia.
  • The sphenochoanal polyp measured 7.5 cm in its greatest dimension and weighed 41 g.
  • The presentation of a sphenochoanal polyp is similar to that of the more common antrochoanal polyp, but the two can usually be differentiated on computed tomography.
  • Endoscopic sinus surgery allows for complete removal of the polyp, including its site of origin, which minimizes the risk of recurrence.

  • [Title] Sphenochoanal polyp: current diagnosis and management.
  • Choanal polyps arise from inflamed, edematous mucosa in the paranasal sinuses.
  • They extend into the choana and cause nasal obstruction and mouth breathing.
  • In most cases, these polyps arise in the maxillary sinus, but rare cases of origin in the sphenoid sinus and other nasal structures have been reported.
  • The presence of a choanal polyp in an atypical location can lead to diagnostic confusion and exploration of the wrong sinus at surgery.
  • The author reports the case of a 15-year-old girl who was diagnosed with a sphenochoanal polyp.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Antrochoanal polyp: a review of sixteen cases.
  • INTRODUCTION: An Antrochoanal polyp, or Killian's polyp is a benign solitary polypoid lesion that affects mainly children and young adults.
  • Studies demonstrate that Killian's polyp generally represents 4-6% of all nasal polyps.
  • It originates from a hypertrophy of the mucous membrane on the maxillary sinus antrum, and it grows for unknown reasons, through the maxillary sinus ostium towards the nasal cavity and the choana--the posterior portion of the pharynx.
  • MATERIALS AND METHODS: Retrospective study, accomplished through a chart analysis from the patients submitted to polypectomy because of Killian's polyps or other nasal polyps, operated from March 1st, 1991 to April 30th of 2001, in the Department of Otorhinolaryngology of the Medical School of the Walter Cantídio University Hospital of the Federal University of Ceará.
  • Predominant symptoms were unilateral nasal obstruction (81.3%) and purulent rhinorrhoea (43.8%).
  • Antrochoanal polyp removal procedure accounted for 21.6% of all the surgical procedures accomplished in the same period for the removal of nasal polyps.
  • CONCLUSIONS: Antrochoanal polyp was an affection that prevailed among children and young adults.
  • Despite maxillary sinus approach to the polyp origin, postoperative recurrence is a possibility.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] [Diagnostic and treatment in nasal polyps of children treated in Wrocław ENT department in the years 1991-2001].
  • BACKGROUND: Nasal polyposis is not often observed in children and usually follows general chronic diseases or disorders of cilliary structure or function and occurs mostly after 10 years of age.
  • This is why in children clinical changes qualified as nasal polyposis should always be verified as congenital diseases or neoplasmatic changes.
  • CASE REPORT: The population: of children treated in the years 1991-2001 in the Wroclaw ENT Department with initial diagnosis of nasal polyposis was presented.
  • Material consisted of 52 children admitted in the years of 1991-2001 to Wroclaw ENT Department with already diagnosed nasal polyposis.
  • In 7 children with initial diagnosis of nasal polyposis hypertrophy of pharyngeal tonsil with vasomotor rhinitis was diagnosed.
  • There was antrochoanal polyp in 10 cases (20,4%), monolateral choanal atresy in 1 case, foreign body of nasal cavity in 1 case and neoplasmatic tumour diagnosed in 5 cases.
  • CONCLUSIONS: The diagnostic difficulties in nasal polyposis in children, except neoplasm, are reflected by the cases with initial diagnosis of nasal polyp and finally diagnosed as foreign body with inflammatory reaction or monolateral choanal atresy.
  • Endoscopic examination of nasal cavity together with radiological diagnostic should be ordered routinely in the unclear cases.

  • [Title] Reconstruction of a "double pathology" on a soft palate: hairy polyp and cleft palate.
  • Hairy polyps of the head and neck are rare congenital tumors that may cause upper aerodigestive tract impairment in newborn.
  • Although cleft palate is a common congenital anomaly, hairy polyp with cleft palate is extremely rare in the newborn.
  • We aimed to present the planning of reconstruction in a patient who has an incomplete cleft palate and defect due to hairy polyp excision on soft palate in this report.
  • In the clinical examination, incomplete cleft palate plus a defect on the posterior side of the left soft palate was observed.
  • On the history, the patient had been operated urgently at the newborn period for a hairy polyp localized on the left soft palate which had obstructed the airway.
  • A case of hairy polyp of nasopharynx with incomplete cleft palate in a neonate and its reconstruction techniques are discussed.
  • The etiology of hairy polyp, hamartoma, teratoma, dermoid cyst and epignathus, their nomenclature, histopathology, clinical features, and management in neonates are also discussed briefly.
