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.

Some investigators have reported a favorable effect of orthognathic surgery on TMJ dysfunction; however, other studies did not show an improvement of TMJ cindylar, and TMJ function worsened in some patients [ 33 ].

Decreased auditory function can most likely be assigned to Eustachian tube changes of orientation as a result of increased and changed muscular tension. J Oral Surg ; 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.

Methods that help to cope with these challenges include the following: Late onset of abducens palsy after Le Fort I maxillary osteotomy. All systematic reviews, randomized controlled trials, clinical trials were considered.

Peripheral condylar sag type II had developed in three of these patients. Also, inputs in diagnosis and plan for treatment and its sequencing, involving the team of the surgeon and the orthodontist, will play a very important role in determining whether the outcome will be favorable. The most common reason for an unclear or high-risk designation was the unblinded evaluation of clinical outcomes.

Blood loss in orthognathic surgery: Intraoperative diagnosis of condylar sag after bilateral sagittal split ramus osteotomy. There exist a large number of varied complications associated with orthognathic surgery procedures.

Report of 36 cases. Diverse TMJ symptoms condlyar occur after orthognathic surgery, ranging from intra-articular noise [ 53 — 55 ], pain, clicking, and crepitus, to condylar resorption [ 56 ]. Fibroscopic eag in patients following maxillary osteotomies in orthognathic condjlar. The permanent increase of surgery technique, methods of orthodontic treatment, and experience is absolutely needed.

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 bone fragments, leading to changes in the occlusion [ 1011 ].

In this study, smoking patients with third molars and diabetics showed a higher incidence of DOH. However, it was limited to the description of complications associated with only one type of orthognathic surgery procedure BSSO.
