title: Micrognathia, obstructive sleep apnoea and cor pulmonale--a case for tracheostomy.
abstract: A patient with congenital micrognathia, hypersomnia and severe pulmonary hypertension which resulted in sudden death during sleep is described. Hypersomnolence is a well-recognized manifestation of the pickwickian syndrome. A less recognized but similar disorder may affect patients with congenital or acquired micrognathia. The pathogenesis of this syndrome and obstructive sleep apnoea are reviewed. Tracheostomy timeously performed may be life-saving and the value of early resort to this apparently drastic procedure in a high-risk patient is emphasized.
