- Abstract:
- Obstructive steep apnea syndrome (OSAS) is a life-threatening disease(1) that is caused by the collapse of the upper airway during sleep. To enlarge the posterior airway space and avoid the collapse of its walls during rapid eye movement (REM) sleep, Powell et al proposed surgical mandibular advancement.(2) Three years later, in 1986, the same authors advocated simultaneous maxillary advancement to achieve better functional and esthetic results. Currently, maxillomandibular advancement (MMA), inclusive of Le Fort I osteotomy, bilateral sagittal split-ramus osteotomy, and anterior inferior mandibular osteotomy (AIMO),(4) is used routinely to treat OSAS in patients with either dentofacial deformities or normal facial morphology. The success rate exceeds 90%.(4) However, the use of this method has been accompanied by problems in establishing preoperatively the amount of advancement needed to address the clinical status and anatomic features of individual patients. The problem remains unresolved because, even though the amount of mandibular advancement is the most important factor influencing clinical outcomes, these variables are not correlated mathematically. 5 Consequently, the rule in OSAS treatment is to pull the mandible forward as far as possible while maintaining an acceptable degree of occlusion and esthetics.(6) This goal can be particularly challenging in OSAS patients without any craniofacial deformities. These considerations led us to develop several technical modifications that can improve the esthetic results without decreasing the clinical efficacy of MMA. This report describes a modified genioplasty in which excessive projection of the chin is avoided in OSAS patients with a sufficient labiodental fold and a normal chin.
