Introduction: Achieving the necessary occlusion for orthognathic surgery is not possible with conventional oral intubation since the tube interferes with the occluding teeth. Sometimes nasotracheal intubation is impossible due to developmental malformations requiring repair. Also, the oral or nasotracheal tube may interfere with the operation or may be damaged during the procedure. In 1986, Hernandez Altemir described a method of submental endotracheal intubation. His intentions were to avoid tracheostomy in maxillofacial trauma cases where short-term intermaxillary fixation was required.
Patients: Between January 2000 and May 2003, 13 patients were operated on, using submental intubation. Eight of these (three females and five males) had surgery for orthognathic malformations.
Methods: The Hernandez Altemir technique was modified to ease the procedure: a sterile nylon guiding tube and the '222 rule' incision were introduced. Eight cases with concurrent complex orthognathic surgery, using this modified technique are reported in this paper.
Results: There were no operative or postoperative complications related to the procedure.
Conclusion: The technique is easy to use, rapid and free of complications compared to 'alternative' intubation methods (tracheostomy, retromolar location of tube, etc.). Submental scarring is acceptable. It is recommended for orthognathic procedures in selected cases.

Influences of patient positioning and general anesthesia on condylar position and surgical accuracy in orthognathic surgery.

Objectives: To assess the effect of patient positioning and general anesthesia on the condylar position in orthognathic surgery.
Materials And Methods: This prospective study included patients undergoing orthognathic surgery between 2019 and 2020. Four weeks prior to surgery (T0) cone-beam computed tomography (CBCT) scans and intra-oral scans (IOS) were acquired in an upright position.

Background: Postoperative nausea and vomiting (PONV) after orthognathic surgery remains one of the most common side effects despite the use of several medications.
Purpose: The study aimed to compare the frequencies of PONV between a combination of metoclopramide with granisetron and granisetron alone.
Study Design, Setting, Sample: A randomized double-blind clinical trial was conducted in 66 consecutive patients who underwent orthognathic surgery at the Department of Oral and Maxillofacial Surgery at Bezmialem Vakif University.
Orthognathic surgery-related condylar resorption in patients with skeletal class III malocclusion versus class III malocclusion: a systematic review and meta-analysis.

School of Dentistry, Complutense University of Madrid, Madrid, 28040, Spain.
Background: Orthodontic-orthognathic treatment is the standard of care for moderate and/or severe skeletal class III (SCIII) malocclusion. Following orthognathic surgery, morphological changes in the temporomandibular joint structures (TMJ) may contribute to condylar resorption (CR).
Objectives: This systematic review aimed to identify the morphological signs of condylar resorption (changes in the condylar head, position, neck, disk, and joint space) following orthognathic surgery in patients with SCIII compared with those with skeletal class II (SCII) malocclusion.

A facial appearance of premature aging due to poor bone support of the soft tissues is frequently found in patients with midface hypoplasia. This study was performed to evaluate the changes in the soft tissues of the cheek area in patients subjected to bimaxillary orthognathic surgery. The cheek line angle and length of 27 consecutive patients who underwent bimaxillary surgery, were measured on cone beam computed tomography scans obtained before surgery and at 1 and 12 months after surgery using 3D software.
