[Obstructive Sleep Apnea: review and a case presentation].

Obstructive sleep apnea may be a life threatening situation if does not get proper attention. Risk factors are easy to find, therefore general dental surgeons should be aware of them and refer if needed. This literature review clearly explains how obstructive sleep apnea is diagnosed and treated. We present a case of a patient with severe obstructive sleep apnea (apnea hypopnea index of 87.5/hour), who underwent bi jaw surgery with 2 piece Le Fort 1 maxiilary advancement, mandibular bilateral sagittal split osteotomy (BSSO) advancement, and genial tubercle advancement. Post-surgery sleep study demonstrated near resolution of previously severe obstructive sleep apnea with overall apnea hypopnea index (AHI) of 3.7/hour consistent with a successful surgical outcome.
