Endoscopic Harmonic Midline Partial Glossectomy in Obstructive Sleep Apnea

Aim: Our study was done to evaluate the role of Endoscopic posterior midline partial glossectomy as a surgical modality for the hypopharyngeal collapse in obstructive sleep apnea patients.

Study design: Prospective case series study.

Place and Duration of Study: Tanta university hospital, otolaryngology department, from October 2017 till March 2019.

Methodology: This was a prospective case series study, conducted on 10 patients from 2017 -2019 with tongue base collapse and normal craniofacial angles, the patients were evaluated preoperative and 6 months postoperative subjectively by Epworth sleepiness scale (ESS) and objectively by polysomnography and lateral cephalometry.

Results: Our study included 10 patients with age (mean ± SD48.70±4.08), BMI( mean ±SD24.45±1.56), 5 patients showed a significant reduction in AHI with a success rate of 50% with a significant change in ESS and the non-significant changes in cephalometric parameters.

Conclusion: Transoral endoscopic posterior midline partial glossectomy can improve the surgical outcomes of obstructive sleep apnea patients.
