Change in cranio-cervical angulation following orthognathic surgery

Change in cranio-cervical angulation following orthognathic surgery.

Changes in natural head posture (NHP) were investigated in 33 patients (10 males, 23 females) with an age range of 16-40 years (median 21 years) following orthognathic surgery to change vertical face height. The reproducibility of the radiographer's technique of taking radiographs in NHP was investigated using a photographic method and found to be acceptable. The patients were divided into two ...

Changes of the Posterior Airway Space Following Orthognathic Surgery in Class III

Objective: Adaptation of the pharyngeal airway space does occur after different surgical strategies of class III patients including mandibular setback, maxillary advancement and bimaxillary surgery. The aim of this study is to conduct a detailed cephalometric evaluation of the alterations taking place in the morphology of the pharyngeal airway space after treatment of class III skeletal deformi...

Osteotomies in Orthognathic Surgery

Orthognathic surgery is mostly performed to correct developmental or acquired oral and maxillofacial skeletal deformities (OMSDs). During the past three decades, significant advances in surgical osteotomy techniques and instrumentation have been developed and carried out in orthognathic surgery. However, the basic surgical principles have more or less remained unchanged. At the same time, numer...

Additional orthognathic surgery following Le Fort III and monobloc advancement.

Severe midface hypoplasia in patients with various craniofacial anomalies can be corrected with Le Fort III or monobloc advancement. Often additional corrective orthognathic surgery is indicated to achieve Class I occlusion and a normal inter-jaw relationship. This study evaluated the incidence of, and the surgical indications for, secondary orthognathic surgery following Le Fort III/monobloc a...
