Abstract
Background: Acquired nasopharyngeal stenosis is a rare and heterogeneous pathological condition that has different causes, generally resulting as a complication of a pharyngeal surgery, especially in patients affected by obstructive sleep apnea (OSA). Different approaches have been proposed for the treatment of nasopharyngeal stenosis but a unique and standardized management has not yet been presented. The aim of our paper is to evaluate the efficacy of our surgical technique, describing its steps and results with the aim to consider it as a possible solution for the treatment of this condition. Methods: This is a retrospective cohort study. Eight patients (mean age 27.25 years old (yo), range 8–67 yo; Male/Female ratio 4/4; mean body mass index (BMI) 26.1) affected by OSA (mean apnea hypopnea index (AHI) before OSA surgery was 22.1) and acquired nasopharyngeal stenosis as a consequence of different pharyngeal surgeries were treated with our modified approach in the Department of Otolaryngology, Morgagni Pierantoni Hospital, Forlì, Italy. Resolution of stenosis and complication rate were the main outcome measures. Results: Complete resolution of the stenosis was achieved in all cases and no complications were recorded at three weeks, six months, and 2 years follow-up. Conclusions: Our technique appears to be a promising method for the management of nasopharyngeal stenosis in OSA patients. However, further studies comparing different techniques and reporting on larger series and longer follow up time are needed to prove the efficacy of the proposed technique.
Highlights
Nasopharyngeal stenosis is an uncommon acquired pathological condition characterized by the reduction and, sometimes, by the complete obstruction of the nasopharyngeal isthmus [1].This particular condition is usually an iatrogenic entity following therapeutic procedures such as: tonsillectomy, adenoidectomy, uvulopalatopharyngoplasty (UPPP), and radiotherapy.there is no clear data in literature about the prevalence of this complication in patients treated with UPPP
We report on our surgical variation in a series of patients affected by obstructive sleep apnea (OSA) and nasopharyngeal stenosis as a consequence of different surgeries
OSA surgery was 22.1) and developed post-surgical nasopharyngeal stenosis were treated with our surgical palatoplasty variation to the one proposed by Toh et al [8]
