Nasal Surgery in Snoring and Obstructive Sleep Apnea

June 1, 2026 updated by: Asmaa Abdullah El Muhammady Ebrahim, Al-Azhar University

Role of Nasal Surgery in Snoring and Obstructive Sleep Apnea

This study aimed to evaluate the effect of isolated nasal surgery on sleep-disordered breathing, particularly apnea-hypopnea index (AHI) and snoring index (SI), Apnea index (AI) and minimal arterial oxygen saturation (MAO2) in adults with obstructive sleep apnea syndrome (OSAS) and nasal obstruction.

Study Overview

Detailed Description

Snoring is the noisy breathing that occurs throughout sleep, resulting from the vibration of the structures in the oral cavity, including the soft palate, uvula, tonsils, base of the tongue, epiglottis, as well as pharyngeal walls.

Obstructive sleep apnea syndrome (OSAS) is a respiratory sleep disorder distinguished by repeated episodes of partial or total occlusion of the upper airways throughout sleep. This blockage is typically associated with a decrease (hypopnea) or total cessation (apnea) of airflow in the upper airways, and sustained thoracic-diaphragmatic respiratory movements.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Apnea-Hypopnea Index
Time Frame: 3 months postoperatively
The Apnea-Hypopnea Index (AHI) is a critical metric used to diagnose and rank the severity of sleep apnea. It measures the average number of times your breathing completely stops (apneas) or becomes severely shallow (hypopneas) per hour of sleep.
3 months postoperatively

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Snoring index
Time Frame: 3 months postoperatively
The snoring index was defined as the number of snoring episodes divided by the hours of total sleep time
3 months postoperatively
