Coblation endoscopic lingual lightening (CELL) for obstructive sleep apnea

Area of Science:

• Otolaryngology
• Sleep Medicine
• Surgical Innovation

Background:

• Obstructive sleep apnea (OSA) significantly impacts patient health and quality of life.
• Tongue base obstruction is a key factor in moderate to severe OSA.
• Limited effective surgical options exist for tongue base obstruction.

Purpose of the Study:

• To evaluate the feasibility, safety, and efficacy of Coblation endoscopic lingual lightening (CELL) surgery.
• To assess CELL as a treatment for tongue base obstruction in OSA patients.
• To analyze surgical outcomes, including pain, complications, and sleep study parameters.

Main Methods:

• Retrospective case series of 25 adult OSA patients with tongue base obstruction.
• CELL performed in combination with relocation pharyngoplasty.
• Transoral resection of tongue base muscle and lingual tonsil using Coblation under endoscopic guidance.

Main Results:

• Mean operation time was 42.6 minutes with minimal blood loss (<50 ml).
• Mean postoperative pain score was low (2.6/10).
• Significant improvements observed: Epworth Sleepiness Scale (p=0.023), Apnea-Hypopnea Index (p<0.001), with an 80% overall response rate.

Conclusions:

• CELL is a feasible and safe surgical option for OSA patients with tongue base obstruction.
• The procedure demonstrates significant efficacy in improving OSA severity and patient-reported sleepiness.
• CELL, combined with relocation pharyngoplasty, offers a promising therapeutic approach for specific OSA phenotypes.
