Abstract

OBJECTIVE:

To describe a new method and the indications for lingual tonsillectomy with endoscopy and coblation, and to document its utility for treating children with persistent obstructive sleep apnea after previous tonsillectomy and adenoidectomy.

STUDY DESIGN AND SETTING:

Case series with chart review in a tertiary pediatric medical center.

SUBJECTS AND METHODS:

Twenty-six patients aged 3 to 20 met the inclusion criteria of polysomnography-proven persistent obstructive sleep apnea after tonsillectomy and adenoidectomy, as well as diagnosis of lingual tonsillar hypertrophy made by flexible fiberoptic sleep endoscopy. Endoscopic-assisted coblation lingual tonsillectomies were performed between June 2005 and January 2008. Preoperative and postoperative nocturnal polysomnogram data were paired and analyzed statistically.

RESULTS:

Statistically significant reductions in the respiratory distress index (RDI) were seen when preoperative and postoperative data were compared (mean, 14.7 vs 8.1). There were similar reductions in the number of obstructive apneas and hypopneas. The mean minimum O2 saturation did not change. Two patients in this series developed adhesions between the epiglottis and tongue base; there appeared to be no consequence for airway or feeding issues.

CONCLUSION:

Endoscopic-assisted coblation lingual tonsillectomy is an effective technique for the treatment of lingual tonsillar hypertrophy causing persistent obstructive sleep apnea in some children.
