Adenotonsillectomy Reduces Obstructive Sleep Apnea and Improves Sleep Quality in Adult Patients
Abstract
BACKGROUND
Adenotonsillectomy is widely established as a first-line treatment for obstructive sleep apnea (OSA) in children; however, its effectiveness and clinical role in adult patients remain less well defined.
PURPOSE
The study purpose was to measure changes in sleep quality and OSA risk in adults following adenotonsillectomy.
STUDY DESIGN, SETTING, SAMPLE
This was a prospective cohort study conducted at Unimed, in Itaperuna, RJ, Brazil, including 28 adult patients diagnosed with OSA.
PREDICTOR/EXPOSURE/INDEPENDENT VARIABLE
The primary predictor variable was the time point (preoperative vs 2 months postoperative).
MAIN OUTCOME VARIABLES
The main outcome variable was therapeutic response, measured using sleep quality, OSA risk, and daytime fatigue.
COVARIATES
Age, sex, body mass index, and baseline sleep quality.
ANALYSES
Descriptive and inferential analyses were performed using χ2, Fisher's exact, and Wilcoxon tests (P < .05).
RESULTS
The sample included 28 subjects with a mean age of 28.4 years (±9.1), of whom 15 (53.6%) were male. Adenotonsillectomy improved sleep quality and reduced OSA risk. The proportion of subjects classified as high-risk for OSA decreased from 71.73 to 0% (P < .0001). Median Pittsburgh Sleep Quality Index scores improved from 9.5 (interquartile range 6 to 11) presurgery to 2.0 (1 to 4) postsurgery (P < .0001). In addition, daytime fatigue and snoring frequency also showed marked reductions postoperatively (P < .0001).
CONCLUSIONS AND RELEVANCE…
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 28 participants or records.
