Evaluation and Management of Antrochoanal Polyps (original) (raw)
2010, Clinical and Experimental Otorhinolaryngology
AI-generated Abstract
Antrochoanal polyps (ACPs) are unilateral, benign lesions originating from the maxillary antrum, commonly causing nasal obstruction and drainage. This study reviews their epidemiology, clinical features, diagnosis using nasal endoscopy and CT, treatment options, and highlights the effectiveness of functional endoscopic sinus surgery (FESS) for complete removal, emphasizing the importance of understanding the polyp's origin to prevent recurrence.

Background and Objectives: This case series is aimed to introduce a new term, antrovestibular polyp (AVP), for an antral polyp herniating anteriorly toward the nasal vestibule and to describe an antral polyp direction of growth through the anterior and posterior fontanelles.Materials and Method: This is a retrospective study involving review of patients who underwent surgery due to maxillary sinus polyp herniating anteriorly toward the nasal vestibular area or posteriorly toward the choana at a tertiary training hospital from January 2007 through July 2016. Their demographic data, computed tomography scan findings, and endoscopic evaluations were analyzed.Results: This study included 49 subjects; 8 (16.33%, 6 males) with AVP and 41 (83.67%, 24 males) with antrochoanal polyps (ACP). The mean ages of AVP and ACP patients were 9 and 14.4 years, respectively (p=0.006). The subjects were identified as AVP when computed tomography scan showed an antral polyp directed anteriorly toward the...
Bilateral antrochoanal polyps: a case report
The Egyptian Journal of Otolaryngology, 2021
Background Antrochoanal or Killian polyp is a rare polyp of the maxillary sinus in adults. It is generally unilateral, implanted on the lateral wall of the maxillary sinus upon the uncinate process. Bilateral cases are very rare; only 14 cases have been cited from 1980 to 2020. Case presentation Our patient presented with a complete bilateral nasal obstruction, this symptom persisted for more than 10 years, with a perceived prolapse in his throat in the last 4 months. Anterior rhinoscopy showed a polyp that took up the totality of his nasal vestibule. Posterior rhinoscopy showed a polyp bulging behind the uvula. The challenge in this case is related to diagnosis decision; conditions with the same clinical presentation are several. Diagnosis was established through the clinical, radiological, and endoscopic aspects, and confirmed by histological findings. Management was obtained through functional endoscopic sinus surgery; no recurrence was noted in the 12-month follow-up, and clinic...
Bilateral Antrochoanal Polyps: An Analysis from Four Cases
Journal of Postgraduate Medicine, Education and Research, 2016
Bilateral antrochoanal polyps (ACPs) are a rare entity. We studied four cases of bilateral ACPs that presented to us. We found a close association of allergy (75%) and chronic rhinosinusitis (CRS) (50%) as etiological factors. The anatomical factors like deviated nasal septum (75%), inferior turbinate hypertrophy (50%), and concha bullosa (25%) are also commonly associated with bilateral ACPs. Endoscopic sinus surgery was performed in all the patients with special emphasis to correct the anatomical factors. Inferior meatal antrostomy was performed in two cases to allow easy access of the angled microdebrider blade for clearing the polyp from the anterolateral and anterosuperior limits of the antrum. After a mean follow-up period of 23 months, no recurrence was found.
Antrochoanal polyp in pediatric age group
Egyptian Journal of Ear, Nose, Throat and Allied Sciences, 2017
Antrochoanal polyp (ACP) is a benign solitary polypoid lesion affecting mainly adults and rarely children. It originates from a hypertrophy of the mucous membrane of the maxillary sinus antrum, and grows through the maxillary sinus ostium towards the nasal cavity and the choana. The clinical data and imaging studies of 39 children with ACP were reviewed. The most commonly affected age group was from 10 to 15 years. Clinical presentations included nasal obstruction, rhinorrhea; and rarely, bloody discharge. Ig-E-mediated allergy was established in 61.5% of the patients and only 17.9% of patients had history of asthma. 92.3% of patients had aberrant nasal anatomy, including septal deviation, pneumatized middle turbinate, and inferior turbinate hypertrophy. The development of ACP could be due to an increased pressure level within the maxillary sinus caused by obstruction of the sinus natural ostium and/or anatomical alteration at the ostiomeatal complex at middle meatus level, in a patient with a pre-existing silent antral cyst, subsequently forced to herniate outside, through the sinus fontanelle. For treatment, we suggest performing wide middle meatotomy in addition to correction of all the predisposing anatomical factors.
Clinical Case Report of a Large Antrochoanal Polyp
Acta Medica (Hradec Kralove, Czech Republic), 2014
Antrochoanal polyps are benign lesions originating from the mucosa of the maxillary sinus. Nasal obstruction and rhinorrhea are their main symptoms. Their endoscopical and radiological appearance makes them relatively easy to diagnose. These polyps are usually presented unilaterally, although bilateral presentation is also possible. We described two cases of atypically giant antrochoanal polyps: in a 15-year-old child and in a 38-year-old man. In both cases, the diagnosis was done by nasal endoscopy and computed tomography (CT) of the paranasal sinuses and supported by histopathological analysis. In the first patient, the excised polyp had the histological characteristic of an angiomatous antrochoanal polyp. Because of their unusual dimension, the combined transoral and endonasal endoscopic approach was performed for complete polyp excision. We discussed the clinical, histopathological and immunohistochemical characteristics of choanal polyps in comparison to inflammatory nasal poly...
