Clinical characteristics of antrochoanal polyps in patients treated in the Department of Pediatric Otolaryngology of the Medical University of Warsaw

Introduction. Antrochoanal polyp (ACP) is a benign lesion originating from the mucosa of the maxillary sinus, growing through the sinus’ ostium (natural or accessory) into the middle meatus and extending into the choana and nasopharynx. ACPs constitute 33% of all nasal polyps in children. Aim. The aim of this study was to evaluate the clinical characteristics of ACP in children treated in the Department of Pediatric Otolaryngology of the Medical University of Warsaw between January 2016 and April 2017. Material and methods. A retrospective analysis of 15 cases was conducted. The following clinical data were analyzed: sex, age, polyp side, associated pathologies, previous surgical procedures and their extent. Result. Ten boys and 5 girls with a mean age of 12.2 (range 9-16) years were included in the study. There were 9 right-sided lesions and 6 left-sided lesions. Seven patients have undergone previous operations, including one patient that had undergone the removal of ACP. Following comorbidities were observed: chronic rhinosinusitis, adenoid hypertrophy, deviated septum, inferior turbinate hypertrophy, otitis media with effusion, and allergy. Three patients underwent other surgical procedures during ACP removal. Conclusions. ACP can lead to unilateral nasal obstruction. Complete removal of the ACP is the key for the successful treatment.
