Insights
Adenotonsillotomy effectively reduces symptoms in children with obstructive sleep apnea syndrome (OSAS). This study shows significant postoperative improvements in OSAS-specific symptom scores after adenotomy or adenotonsillotomy.

- Surgical Outcomes
Abstract:
In order to assess the effectiveness of adeno(tonsillo)tomy in relation to obstructive sleep apnea syndrome, OSAS-specific symptoms were prospectively recorded in this study.The total collective consisted of n = 111 children (3-6 years, ♂ 55% ♀ 45%) who underwent adenotomy (77%) or adenotonsillotomy (23%) at ENT University Hospital Ulm. OSAS-specific symptoms were assessed using a questionnaire (day of surgery, follow-up: 3 months) and results were presented using box-whisker plots for the overall collective and the AT and ATT surgical techniques (significance level α=5%). Bar charts were used to illustrate the pre- and postoperative risk stratification.On average, the postoperative Brouillette score (-3.41 AT: -3.33 ATT: -3.68) was significantly lower for the overall collective and the individual surgical techniques than preoperatively (-0.22 AT: -0.49 ATT: 0.7). The average OSA-18 score was significantly lower postoperatively for the overall collective and the individual surgical techniques (33.2 AT: 33.5 ATT: 31.9) than preoperatively (61.2 AT: 59.1 ATT: 68.6).In the presence of obstructive sleep apnea syndrome, AT and ATT surgical techniques are effective treatment methods for reducing symptoms.

Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants.
