Summary
Midline glossectomy (MLG) can improve obstructive sleep apnea syndrome (OSAS) by enlarging the airway. This study found MLG effective in 42% of patients, particularly those less obese and with specific jaw structures.
Area of Science:
- Otolaryngology
- Sleep Medicine
- Surgical Innovation
Background:
- Obstructive sleep apnea syndrome (OSAS) is a common disorder requiring effective treatments.
- Current surgical options for OSAS have varying success rates.
- Hypopharyngeal collapse is a key factor in some OSAS cases.
Purpose of the Study:
- To evaluate the efficacy and safety of midline glossectomy (MLG) as a treatment for OSAS.
- To identify patient characteristics associated with successful MLG outcomes.
Main Methods:
- A cohort of 12 patients with OSAS underwent midline glossectomy (MLG).
- MLG was performed as a primary treatment or after failed uvulopalatopharyngoplasty (UPPP).
- Patient outcomes were assessed using the Respiratory Disturbance Index (RDI) and cephalometric analysis.
Main Results:
- Five out of 12 (42%) patients were responders, with a significant decrease in RDI.
- Non-responders showed no significant change in RDI.
- Responders were less obese (BMI 30.6 vs. 37.9) and more retrognathic (S-N-B 74.4° vs. 79.3°).
- Minor complications occurred, but no major adverse events or persistent functional deficits were observed.
Conclusions:
- Midline glossectomy (MLG) can be an effective treatment for a subset of OSAS patients with hypopharyngeal collapse.
- Patient selection based on obesity and cephalometric features may predict treatment success.
- MLG offers a direct surgical approach to enlarge the hypopharyngeal airway in OSAS management.
