Insights
Adenotonsillectomy significantly improves mixed apnea index (MAI) and central apnea index (CAI) in children with moderate-to-severe obstructive sleep apnea syndrome (OSAS). This surgery normalizes non-obstructive apneas in most affected children.
Area of Science:
- Pediatric Sleep Medicine
- Otolaryngology
- Respiratory Physiology
Background:
- Obstructive sleep apnea syndrome (OSAS) in children often presents with mixed and central apneas.
- Non-obstructive apneas are frequently observed in pediatric OSAS, impacting treatment strategies.
Purpose of the Study:
- To investigate the impact of adenotonsillectomy on mixed apnea index (MAI) and central apnea index (CAI).
- To evaluate the effectiveness of adenotonsillectomy in children with moderate-to-severe OSAS and non-obstructive apneas.
Main Methods:
- Retrospective analysis of polysomnographic data from 80 children with moderate-to-severe OSAS.
- Children without comorbidities undergoing adenotonsillectomy were included.
Main Results:
- Adenotonsillectomy led to significant reductions in MAI (1.2 to 0.5) and CAI (1.0 to 0.5).
- Post-surgery, 91.7% of children showed normalized MAI and 75.6% normalized CAI.
- The study included 80 children (55 boys, 25 girls) with a median age of 3.6 years.
Conclusions:
- Adenotonsillectomy effectively reduces both obstructive and non-obstructive apneas in children with moderate-to-severe OSAS.
- The procedure demonstrates significant improvements in MAI and CAI, suggesting its benefit for central and mixed apneas.
Purpose:
Investigate the effect of adenotonsillectomy on mixed apnea index (MAI) and central apnea index (CAI) in children with moderate-to-severe obstructive sleep apnea syndrome (OSAS).
Methods:
Observational retrospective analysis of polysomnographic data in children diagnosed with moderate-to-severe OSAS and without comorbidity, submitted to adenotonsillectomy.
Results:
Data were available for 80 children, 55 boys and 25 girls, with a median age of 3.6 years (2.1-5.9). Before surgery AHI was 14.1 (11.0-18.4) per hour, with a median preoperative OAI of 7.1 (4.1-10.6), MAI of 1.2 (0.6-1.6) and CAI of 1.0 (0.4-2.0). Adenotonsillectomy caused significant improvements in MAI, from 1.2 (0.6-1.6) to 0.5 (0.1-0.8) (p < 0.001) and CAI from 1.0 (0.4-2.0) to 0.5 (0.1-0.9) (p < 0.001). This represents a normalization of MAI in 91.7% and CAI in 75.6% of children that had an abnormal value prior surgery.
Conclusion:
Non obstructive apneas are common in children with OSAS. Adenotonsillectomy caused significant decrease not only in OAI, but also in MAI and CAI in children with moderate-to-severe OSAS.

Etiology
Three primary contributing factors have been identified.
Chronic Pharyngitis
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. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
