Purpose: This article reviews the evolution of outpatient orthognathic surgery from 1988 to 1995 at the University of Texas Health Science Center at San Antonio.
Patients And Methods: A total of 328 patients had orthognathic surgery from 1988 to 1995. Two hundred and five (124 females, 81 males) were treated on an outpatient basis in the surgical suite of the dental school. Procedures included bilateral sagittal split osteotomies (BSSO), Le Fort I osteotomies (LFI), horizontal mandibular osteotomies (HMO), rapid palatal expansions (RPE), and combinations of the above. Additional procedures such as submental liposuction, blepharoplasty, dorsoseptorhinoplasty, and otoplasty were performed on 22 patients. Patient age ranged from 13 to 64 years, (average age 25).
Results: Ninety-four (46%) of the patients were discharged the day of surgery. One hundred and two (51%) were admitted for 23-hour observation, and five (2.4%) were admitted for longer than the 23-hour observation period. Anesthesia time over 4:28 significantly correlated with admission for observation status. There was no significant difference between LFI and BSSO in relation to admission for observation status.
Conclusions: The number and complexity of orthognathic procedures increased dramatically over the study period. The length of anesthesia time, but not the specific procedure, correlated significantly with admission to observation status. There were few unexpected complications, with considerable cost reduction and convenience for the patients.

Effect of Dexmedetomidine on Blood Loss and Patient Outcomes in Orthognathic Surgery: A Randomised Clinical Trial.
Int Dent J
January 2025
Department of Dental Pathology, Faculty of Dentistry, Chulalongkorn University, Bangkok, Thailand.
Introduction And Aims: Blood loss is a common side-effect in orthognathic surgery. Deliberated hypotensive anaesthesia can reduce blood loss. The purpose was to evaluate the effect of add-on dexmedetomidine compared with the usual hypotensive drug bolus on blood loss and patient outcomes in orthognathic surgery.

Materials And Methods: Two distinct social media searches were conducted using specific search phrases on TT and YT. For each search phrase, 30 videos were gathered from each platform, and details such as number of views, likes, and comments were recorded for each video.
Jawline improvement using patient-specific angle implants with virtual planning in orthognathic surgery.

Department of Oral and Maxillo-Facial Surgery, Head and Neck Institute, University Hospital Center of Nice, 31 avenue de Valombrose, 06100, Nice, France; Nice Côte d'Azur Clinical Research Unit (UR2CA), France. Electronic address:
There has been a recent increase in the global demand for jawline augmentation. Managing angle definition in patients undergoing orthognathic surgery remains challenging owing to the characteristics of classic mandibular osteotomy, which mostly allows sagittal mandibular movements but cannot modify the ramus height. The advent of computer-assisted surgical planning and computer-aided design/computer-aided manufacturing techniques for patient-specific implant fabrication has introduced new methods for jawline management.

Evaluation of cortical bone thickness at the nasomaxillary and zygomaticomaxillary buttresses using cone-beam computed tomography imaging for Le Fort I osteotomy.

School of Dentistry, China Medical University, Taichung, Taiwan.
Background/purpose: Studies have indicated that 50%-55% of the population have malocclusion, and approximately 5%-10% require orthognathic surgery to correct this condition. Optimal placement of plates and screws significantly affects the success rate of the surgery and postoperative stability. This study evaluates the cortical thickness of the maxillary bone in the nasomaxillary and zygomaticomaxillary buttress regions in Taiwanese patients based on cone-beam computed tomography (CBCT) images.
