Polysomnography Results in Pre and Postoperative Patients with Nasal Function Correction Surgery

Location: 136
Introduction: Obstructive Sleep Apnea (OSA) is a multifactorial sleep disorder in which nasal obstruction is one of the main causes including internal and external nasal valve collapse. The purpose of this study is to determine the effectiveness of nasal valve repair surgery in patients with nasal valve collapse and OSA to improve the outcomes in polysomnographic results.

Methods: A retrospective analytical observational study of a historical cohort was performed between august 2021 and july 2024, in Fundación Santa Fe de Bogotá. Adult patients with OSA diagnosed by type I polysomnography associated with nasal valve collapse were included. In selected patients, nasal valve repair surgery was performed analyzing the following sleep parameters: Sleep efficiency, AHI, sleep apnea severity, oxygen saturation, obstructive apneas, central apneas, mixed apneas and hypopneas index before and 3 months after surgical procedure. Independent variables such as age, gender, height, weight and body mass index were taken into account for data analysis.

Results: 10 patients met inclusion criteria by the time of data analysis. 6 improved their AHI (p=0.0840) and severity score was reduced in 4 patients (p=0.287); 8 patients improved their obstructive apnea index (p=0.3795), 4 patients improved their mixed apnea index (p=0.1633) and 7 improved their hypopnea index (p=0.0349). Furthermore, 5 patients improved their oxygen saturation levels (p=0.9180), all patients improved their sleep efficiency (p=0.0126) and 3 patients were able to remove CPAP therapy after surgery (p=0.369).

Conclusions: Nasal valve repair surgery had a notable impact in improving sleep efficiency in all patients and significantly reduced the hypopnea index. Other sleep parameters didn’t have significant variability before and after surgery. Even though there was improvement in AHI and obstructive apnea index, further studies with a bigger sample size need to be conducted to determine the real impact of nasal valve repair surgery in these sleep parameters.
