Detailed Description

patients participating in this study were randomly allocated into parallel group to evaluate the therapeutic effects on snoring . one group received low level laser therapy targeting soft palate while second group received oropharyngeal and tongue exercises to strengthen upper air way muscles the treatment outcome were evaluated before and after the intervention period . the primary clinical assessment for snoring risk and severity was conducted using berlin questionnaire .

statistical analysis was performed to compare the pre and post treatment result between the groups to identify the most effective non invasive treatment modality for snoring in sleep apnea patients
