Obstructive sleep apnoea syndrome (OSAS) is caused by obstruction or narrowing of the airway at various levels. The repair of one site only will not alleviate the syndrome if there are obstructions in other sites. Epiglottis prolapse during inspiration is an unusual cause of airway obstruction and a rare cause of OSA.Twelve cases of OSAS due to an abnormal epiglottis are presented. We present our approach to the diagnosis using fibre-optic examination of the hypopharynx, and our treatment using endoscopic carbon dioxide laser partial epiglottidectomy.We found in our series that in 11.5 per cent of patients who failed the uvulopalatopharyngoplasty procedure, the reason was a narrow airway at the hypopharyngeal level caused by an abnormal epiglottis. It is our suggestion that in these cases a laser partial epiglottidectomy should be performed. The results of this study show that partial epiglottidectomy can increase the cure rate of patients with obstructive sleep apnoea syndrome by 10–15 per cent.

Vertigo and dizziness are not common in childhood, but are probably present more often than was formerly thought. These symptoms caused mainly by otitis media and middle ear effusion, two of the most common diseases in children, have been neglected for a long time, both in the literature and in practice, until recently. The purpose of this study was to determine objectively the incidence of balance-related symptoms in children with long-lasting middle ear effusion and to discover whether these symptoms resolve after the insertion of ventilation tubes. One hundred thirty-six children, ages 4 to 9 years, were given electronystagmographic tests and the Bruininks-Oseretsky tests for motor proficiency before and after tube ventilation of the middle ear. The results were compared with those in 74 healthy children with no history of middle ear diseases. Pathologic findings were found in 58% of the children with chronic middle ear effusion, as compared with only 4% of the control group. The symptoms and signs of balance disturbances resolved in 96% of the children after ventilation tube insertion. The results of this study indicate that balance-related symptoms often encountered in young children may result from chronic middle ear effusion and that these symptoms will resolve after evacuation of the effusion and ventilation of the middle ear.

Cholesteatoma formation associated with VT placement occurs in 1.1% of the ears that are operated on, and therefore it should be discussed with patients or parents prior to surgery. Periodic and long-term follow-up microscopic examinations of the eardrum should be performed in all patients following tubal extrusion or removal, especially in those at high risk for developing a secondary cholesteatoma, to detect this complication as early as possible.
