Obstructive sleep apnoea syndrome presenting as lingual ulceration.

Two patients with obstructive sleep apnoea syndrome are reported where the initial presenting complaint was of lingual ulceration. This unusual presentation has not been reported previously. Both patients experienced frequent apnoeic episodes during sleep with a profound fall in the arterial oxygen saturation. It is postulated that the lingual ulceration resulted from repeated trauma to the tongue by the teeth as the patient made violent inspiratory efforts at the termination of an apnoeic episode. The diagnosis of sleep apnoea syndrome was based upon suggestive symptoms of snoring, morning fatigue and day-time somnolence plus a minimum of 15 apnoeic episodes per hour of sleep. The first-line investigations of this condition are available in all district general hospitals and a diagnosis of sleep apnoea syndrome obtained. Referral to a regional sleep study centre may be appropriate prior to the commencement of therapy. Management is predominantly medical, consisting of weight loss and the administration of nocturnal nasal continuous positive airways pressure.
