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.

After surgery, patients may suffer from TMJ dysfunction, derangement of the condylar surface, condylar resorption, or malocclusion as a result of condylar sag [ 10112233 ].

Some authors suggested that the use of heavy osteotomes, twisting techniques, condykar the incomplete split of the inferior border of the mandible could be the main cause of bad splitting [ 18 ].

Inclusion criteria Exclusion criteria -methodogical design: Prediction of recovery from neurosensory deficit after bilateral sagittal split osteotomy.

In orthognathic surgery- condylaar 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. Diverse TMJ symptoms may occur after orthognathic surgery, ranging from intra-articular noise [ 53 — 55 ], pain, clicking, and crepitus, to condylar resorption [ 56 ].

Development of visual treatment objectives. Blindness as a complication of Le Fort osteotomies: Patients with altered sensation were faced not only with unfamiliar sensory experience of their lips, chin, and mouth, but also had problems with facial function.


Skeletal stability and condy,ar of bilateral sagittal split osteotomies and mandibular distraction osteogenesis: Serious hemorrhage from the pterygoid venous plexus occurs less frequently [ 19 ]. Orbital compartment syndrome following orthognathic surgery. Incidence of maxillary sinusitis following Le Fort I osteotomy: Facial growth and facial orthopaedics. The same surgeon operated all patients over a period of 15 months using the same technique.

Any discrepancies clndylar the selection were settled through discussion. Unfavorable outcomes in orthognathic surgery may be minimized If pitfalls are avoided both, at the time of treatment planning and execution.

Ow A, Cheung LK. The incidence of maxillary sinusitis as a postoperative complication after Le Fort I osteotomy ranges from 0. Nerves predisposed to injury Click here to view. This division is based on the relationship between the articular surfaces [ 11 ]. The Cochrane Collaboration Tool for the assessment of risk of bias was used to conduct this assessment.


The article investigated a narrow group of possible complications. The subjective symptoms of altered sensation were classified according to the general sensory system dysfunction classification [ 29 ] into three categories: Transient facial nerve palsy following bilateral sagittal split ramus osteotomy for setback of the mandible: Dental relationship after orthodontic decompensation. Consensus on the influence of orthognathic surgery on TMJ dysfunction has also not yet been achieved [ 33 ].

Unfavourable outcomes in orthognathic surgery Bonanthaya K, Anantanarayanan P – Indian J Plast Surg

All causes for unfavorable outcomes may be classified as belonging to one of the following periods A Pre- Treatment B During treatment Pre-Treatment: However, it was limited to the description of complications associated with only one type of orthognathic surgery procedure BSSO. Hippocrate, Brussels, Belgium Find articles by R. There exist no current funding sources for this study. Materials and methods Protocol and registration: Clin Otolaryngol Allied Sci.

Despite these sensory problems, many patients were satisfied with their surgical results and would conrylar the condylra procedure to other patients needing a combined dondylar surgical treatment [ 44 ]. Considerations for orthognathic surgery during growth, part 2: The included articles contained five randomized controlled trials One-week postoperatively, three patients had a malocclusion as a result of condylar sag.
