Sleep apnea syndrome has been reported by Guilleminault et al. in 1976 and it is a rare condition. The major symptoms of this syndrome are excessive daytime somnolence, sleep apnea and loud snoring.
Recently, we have experienced one case of microgenia with sleep apnea syndrome. Our present case, a 29-year-old Japanese woman complained of retrogression of the mandible and loud snoring. She was operated on horizontal advancement genioplasty and her symptoms then improved.
This case suggested that horizontal advancement genioplasty was effective for sleep apnea syndrome, and we considered the result that her upper airway was extended by this operation.
