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.

Methods for testing sensory nerve function can be divided as follows: A retrospective study with discussion of 2 interesting clinical situations.
However, the total number of complications might be underestimated because surgeons may be unable to easily report the complications due to their own professional obligations and involvement.
Plate fixation of extra-oral subcondylar ramus osteotomy for correction of mandibular prognathism: These results demonstrated that only 3 out of 44 assessed studies [ 273041 ] met all of the requirements of our critical appraisal.

Some aural symptoms tinnitus, fullness, otalgia and auditory changes may occur as a consequence of surgical edema or lymphoedema and hematoma [ 38 ].
Transposition of the mental nerve in orthognathic surgery. The most important part of surgery for avoiding such complications is the positioning of bony fragments and rigid fixation. Incidence of maxillary sinusitis following Le Fort I osteotomy: Condylar sag can be defined as an immediate or late change in position of the condyle in the glenoid fossa after the surgical establishment of preplanned occlusion and rigid fixation of the condy,ar fragments, leading to changes in the occlusion [ 1011 ].
Furthermore, segmentation of the maxilla additionally decreased sensory function in the palate and gingiva [ 44 ]. Bilateral sagittal split osteotomy and temporomandibular disorders: Progressive condylar resorption after mandibular advancement.
Concylar addition, the data investigation was performed by only one reviewer, and the assessment of the potential risk of bias was unclear. Grubb J, Evans C.
