Available in PDF, EPUB and Kindle. Book excerpt: Problem: The effect of orthognathic surgery on temporomandibular joint pain and dysfunction is a controversial topic with inconclusive evidence. Purpose: To determine the effect orthognathic surgery has on TMJ-related pain and function, and identify pre-operative patient risk-factors to predict TMJ outcome. Methods: Data was collected pre-operatively and 6 months post-operatively. Statistical analysis was completed, with a focus on mandibular range of motion and TMJ related pain. Results: 56 patients completed the study. Pre-operative overjet ≥6mm, Class II malocclusion, large mandibular advancement, and completion of a functional genioplasty were associated with a decreased MIO. Self reported frequency of joint pain, clenching, and objective clicking decreased. Self-reported joint noises were significantly decreased. Conclusion: TMJ related pain is likely to remain unchanged following surgery, however patients may notice a decrease in their pain frequency. A decrease in opening requiring further intervention can occur, but is rare. TMJ clicking and parafunctional clenching may decrease.

Abstract: Background Distraction osteogenesis (DO) was first applied on the human craniofacial skeleton in 1992 by McCarthy et al.1 who performed lengthening of the mandible in patients with hemifacial microsomia and Nager's syndrome. Further advances in this field have since then led to the widespread use of this modality for the treatment of numerous congenital and acquired craniofacial skeletal anomalies. In 2001, a review by Swennen et al2 concluded that up to year 1999, this form of treatment was gaining intense popularity but that the main drawbacks included insufficient data on long term results and relapse. A systematic review of the last decade on functional outcomes and long term complications following distraction osteogenesis of the facial skeleton is presented. Methods A structured systematic literature search, with predefined inclusion and exclusion criteria from relevant computer databases and journals were performed. The journals were evaluated and critically appraised by 2 reviewers separately in 3 rounds. Papers were categorized according to the level of evidence, the quality of methodology and the specific field of functional outcomes and long term complications. Results were then categorized according to the type of distraction movements, ie maxillary advancement and mandibular lengthening. Results A total of 42 papers comprising of 16 studies for maxillary advancement and 26 studies for mandibular lengthening were included in this review. Maxillary advancement was found to be beneficial in patients with cleft maxillary hypoplasia in terms of achieving aesthetic outcome but the risk for velopharyngeal insufficiency remains uncertain. The achieved maxillary advancement was stable if performed on adult patients while a recurrence of midface retrusion was noted if DO was performed on growing patients. Overcorrection was recommended in these cases to an estimated value of 20-50%. Mandibular lengthening was 99% successful in relieving respiratory obstruction in patients with isolated Pierre Robin Sequence (PRS) or syndromic micrognathic infants preventing the need for tracheostomy in the long term, and in 89% successfully decannulating infants with pre-existing tracheostomy. However, feeding and growth outcomes after airway obstruction was relieved remain unknown due to lack of sufficient evidence. Unilateral mandibular DO was successful in achieving aesthetic symmetrical facial balance in patients with hemifacial microsomia however a total loss of corrected distraction length was noted by the end of growth period if DO was performed during growth. Conclusions DO achieved stable results in terms of lengthening the maxilla and mandible but was also noted to cause restricted growth potential of the distracted bone. Hence, the benefits of performing DO during active growth should be weighed against the likely need for a second surgery due to a growth deficit of distracted bone and future surrounding bone growth. However DO in adults remains an alternative to conventional orthognathic surgery and choice of treatment should be patient centred.

Available in PDF, EPUB and Kindle. Book excerpt: This book is a comprehensive guide to the surgery-first orthognathic approach for patients with malocclusion and skeletal disharmony, which has been successfully applied by the authors in their practices over the past 15 years. The approach breaks with the time-tested principles of traditional orthognathic surgery in that corrective bone surgery is performed first, without the removal of dental compensations, followed by orthodontic finishing. All aspects are covered with the aid of numerous illustrations, the aim being to provide surgeons with a systematic educational tool that will enable them to introduce the approach into their own practice. In addition, the book addresses one of the hot issues in orthodontics, occlusal plane-altering orthognathic surgery, in which surgical modification of the occlusal plane is employed to treat various types of dentofacial deformity and improve facial proportions. This promises to become a very powerful tool in modern orthognathic surgery.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Orthognathic surgery encompasses various surgical procedures used for the correction of dentofacial deformities from malocclusions, prognathism, retrognathism, obstructive sleep apnea, to TMJ disorders and others. While the primary objective of orthognathic surgery is to optimize the occlusion and improve overall masticatory function, enhancement of the facial aesthetics is also an outcome of concern. However, tissue manipulation can result in unpredictable and sometimes, unfavorable outcomes. Thus, it is important to understand the impact hard tissue movement has on the soft tissue. Purpose: The primary outcome of this study was to determine the hard to soft tissue ratio following orthognathic surgery. Secondary outcomes focused on evaluating changes in soft tissue. Methods: Pre and post-operative cone beam computed tomography (CBCT) scans were taken prior to surgery and between 2 and 4 weeks post-operatively. 3D Photos were captured pre-operatively and at 3-months, 6-months and 12-months post-operatively. Image analysis was done using Dolphin® software. Three separate analysis were done: the magnitude of bony movement (HT), comparing hard to soft tissue movement (HT: ST), and changes in soft tissues (ST). The primary and secondary outcomes were then evaluated using these analyses stratified by time, sex, procedure type, age and BMI. Both a Wilcoxon signed-rank test and a regression model fit were used to evaluate the data. All patients planned for orthognathic surgery at Dalhousie University were screened and enrolled if they met the inclusion criteria. Results: 12 total patients completed the 12-month follow up, 19 patients completed the 6-month follow up and 44 patients completed the 3-month follow up. There were 3 treatment groups: LF, BSSO and LF BSSO. There was no statistically significant change in the HT: ST ratio at 12-months post-operatively. There was a trend in the data that showed maximal increase in the HT: ST ratio at 6 months (1: 1.53, n=19, p=0.38), however it was not statistically significant. The nasolabial angle showed the greatest change with maxillary surgery (2.56mm, n=7, p=0.03) and in males (1.45mm, n=17, p=0.04). The mentolabial angle changed more in patients in the BSSO treatment group (5.08mm, n=11, p=0.03). The alar width increased after surgery (2.58mm, n=14, p=0.001), with the greatest changes in the LF treatment group (1.77mm, n=14, p=0.06). There were no significant differences seen in the mouth width, height of philtrum, and upper and lower lip thicknesses. Conclusion: The hard to soft tissue ratio does not change significantly 12-months post-surgery. Minor soft tissue changes were seen at the level of the nasolabial angle, mentolabial angle and the alar width. The patient attrition rate was significant in this study, and the study findings should be interpreted accordingly.
