Purpose: To evaluate a method to identify condylar sag intraoperatively by clinical examination after bilateral sagittal split osteotomy (BSSO). Methods: We. Condylar sag is an immediate or late alteration in the position of the condylar process in the glenoid fossa after the fixation of the osteotomy. Peripheral condylar sag (type II) had developed in three of these patients. In 15 patients central sag was diagnosed. One-week postoperatively, three patients.

Orthod Craniofac Res ;6: Peripheral condylar sag type II had developed in three of these patients. Conservative treatment consists of controlling blood pressure and administering intravenous fluids and blood transfusion. Intraoral oblique ramus osteotomy with maxilla-mandibular fixation appears to be more favorable for TMJ than BSSO with rigid fixation, especially dondylar patients with preoperative symptoms [ 24 ].
Intraoperative diagnosis of condylar sag after bilateral sagittal split ramus osteotomy.
This review was registered on http: Optimizing benefit to the patient. A retrospective study with discussion of 2 interesting clinical situations. Hemorrhage after LeFort I surgery was described in 9. The condylat of the second systematic review [ 1 ] was well designed and provided reliable conclusions. Introduction Orthognathic surgery procedures are frequently used to correct skeletal angle class II and III deformities, dentomaxillofacial deformities, mandibular laterognathia, and maxillofacial asymmetries [ 1 — 4 ].

Further risk factors for IAN injury and impairment are the following: Nasotracheal intubation may also cause swelling of the soft tissues in the nasotracheal area, blocking the Eustachian tube, and precipitating middle ear effusion [ 38 ]. An explanation of this result could be the h evaluation period and the administration of several 2—5 doses of intravenous antibiotics for such patients [ 20 ].
Functional and radiographic long-term results after bad sat in orthognathic surgery. Essentials of Orthognathic Surgery. In orthognathic surgery- as in any other discipline of surgery- which involves changes in both aesthetics and function, the patient motivation for seeking treatment is a very important input which may decide, whether the outcome is going to be favorable or not.
