Although OGS can be used to reposition the condyle, postoperative complications such as aggravated clicking may occur, causing patients to question the efficacy of mandibular setback surgery. The present study recorded whether patients with mandibular prognathism had preexisting TMJ clicking and evaluated postsurgical TMJ clicking outcomes.The most common birth anomalies within the head and neck are orofacial clefts (OFCs) and prognathism. Orofacial clefts are disorders with a range of phenotypes such as the cleft of the lip with or ...The term mandibular prognathism refers to an abnormally long mandible relative to the length of the maxilla. However, in rabbits the primary defect is actually a short maxilla in relation to a mandible of normal length, so the common name is actually a misnomer. Both conditions are known to occur in humans ( Rubbrecht, 1939 ), dogs, and sheep ...1. Surgical treatment for mandibular prognathism using vertical ramus osteotomy does not affect tongue pressure, contradicting the view that the tongue is the main cause of skeletal relapse after mandibular setback. 2. There is no need for routine tongue size reduction prior to orthognathic surgery for mandibular prognathism.The subjects were 22 patients in whom mandibular prognathism was corrected by bilateral sagittal split ramus osteotomy; either one jaw or two jaw surgery. Polysomnography was performed before surgery and 6 months after surgery, and the apnea hypopnea index (AHI) and arterial oxygen saturation during sleep were measured to assess respiratory ...In 1927 Wassmund described the inverted “L” osteotomy.
