A Case of Huge Lingual Tonsillar Hypertrophy Causing Obstructive Sleep Apnea in Adult

ABSTRACT

Obstructive sleep apnea is characterized by repeated episodes of obstructive apnea and hypopnea. Lingual tonsillar hypertrophy causing obstructive symptoms is a rare disease in adults. Recently, we experienced a case of obstructive sleep apnea due to massive lingual tonsillar hypertrophy. The patient had tonsillectomy as a child and underwent adenoidectomy three years prior to the current presentation due to snoring and sleep apnea. However, symptoms did not improve and were recently aggravated. The upper airway evaluation and polysomnography revealed excessive lingual tonsillar hypertrophy and severe obstructive sleep apnea. An enlarged lingual tonsil was successfully removed using a Coblator. No recurrence was observed, and the obstructive sleep apnea was resolved postoperatively.
