Overview

Obstructive sleep apnoea (OSA) is a group of symptoms and disease stated that occur as a consequence of repetitive pauses in breathing (hypopnoic and/or apnoic pauses) during sleep. Hypopnoea and/or apnoea is usually caused by an obstruction of the upper airways, most commonly by pathological lesion of the nose, narrowing of retroglosal and retropalatal space, craniofacial abnormalities and obesity. This case report presents a rare cause of severe OSA (AHI 32, saturation under 90% observed in 8.4% of the total sleep time) due to pseudocyst of the floor of the mouth that obstructed the retroglosal space. Excision of the pseudocyst led to significant improvement in snoring, normalization of AHI a patient cure.

Key words:
obstructive sleep apnoea – floor of the mouth – retroglosal space – pseudocyst
