Abstract
Obstructive sleep apnoea (OSA) is a serious condition that can be the cause of a number
of systemic symptoms and conditions. The diagnosis of OSA is made by clinical and
radiological examination, with polysomnography as the gold standard for recording
the severity of the disorder. Among the many therapies offered for OSA, maxillomandibular
advancement is recognized as a powerful technique for relieving upper airway obstruction.
The upper airway may be further opened by an advancement genioplasty, but this may
compromise facial aesthetics by over-projecting the chin prominence. To overcome this
difficulty, a modified genioplasty is presented. This is designed to enable a rotational
repositioning that allows for advancement of the genioglossus attachments but also
avoids an excessive projection of pogonion, which would otherwise result in an unfavourable
profile.
