Sleep Apnea is a type of sleep disorder characterized by pauses in breathing or instances of shallow or infrequent breathing during sleep. When breathing is paused, carbon dioxide builds up in the bloodstream. The brain is signaled to wake the person to breathe in air. Breathing normally will restore oxygen levels and the person will fall asleep again. This phenomenon makes the patient tired in the morning due to the restless sleep and may cause many systemic problems including heart attack, irreversible heart enlargement, fatigue, obesity, depression and loss of sexual desire.

Dr. Momtaheni office is uniquely equipped to examine and diagnose snoring and sleep apnea by utilizing 3D airway imaging analysis, nasoendoscopy and a through head and neck examination.  In some cases, it is necessary that patients have a sleep study called Polysomnography.

In the early 1980’s, Dr. Momtaheni noticed that many of his patients with a retruded lower jaw and OSA improved their breathing and eliminated their OSA.  He started to bring the lower jaw forward by appliance therapy and or surgery.  He recognized a significant improvement of patient's breathing and snoring conditions.  He then contributed to a textbook of Oral and Maxillofacial Surgery Chapter in OSA and shared his cases to the publication,  William M. Bell, “Modern Practice in Orthognathic and Reconstructive Surgery.” Chapter in Sleep Apnea, W.B. Saunders, 1992.  He has published and lectured on this subject nationally and internationally.  In 2011, he Directed the first Dental School sponsored continuing education course in “Snoring and Sleep Apnea: A Comprehensive Review,” at Columbia University College of Dental Medicine.
