surgery address?
Apnoea is defined as a temporary absence or cessation of breathing. The most common cause of sleep apnoea in adults is obstructive sleep apnoea/hypopnoea syndrome(OSAHS). OSAHS is a condition in which a person experiences repeated episodes of apnoea because of a narrowing or closure of the oro-naso-pharyngeal airway during sleep. This could occur for various reasons. Essentially and simply put, there is not enough space in the upper part of the airway (the mouth, nose and throat) to allow adequate flow of air to the lungs for normal breathing. A common misconception unfortunately, especially amongst many doctors is that one has to have a retruded lower jaw for a patient to benefit from orthognathic surgery either as a single jaw procedure or as a bimaxillary advancement, sometimes also with a genioplasty. This is absolutely incorrect and outdated thinking, which condemns patients to lifelong CPAP treatment in many cases from our own personal experience over many years, unnecessarily.
