Background Different advantages of virtually planned and guided mandibular reconstructions have been described. Functional analyses and comparisons with conventionally reconstructed patients. Methods We retrospectively analyzed 30 cases of mandibular reconstructions that involved virtually planned or conventional microvascular, fibular free flaps that occurred between April 2011 and December 2014 at a single center. The results were also compared with a healthy cohort of 30 participants. Axiographic measurements were performed postoperatively, and uni- and multivariate regressions analyses were performed to determine the association between possible predictor variables on functional outcome...

Preoperative delineation of the mandibular canal and surrounding cortical bone thickness is mandatory prior to bilateral sagittal split osteotomy (BSSO). The cortical bone thickness of 101 cadaveric mandibles was measured to define the mandibular canal. The mandibles were cut at the anterior ramus, at the third, second, and first molar, and at the premolar. The cortical bone thickness was measured between the mandibular canal and inferior border, buccal cortex, and lingual cortex at each cutting point. No difference was found between the right and left sides of the mandible, or between males and females, with one exception: males were found to have thicker inferior cortical bone at the premolar site than females...

Brain-derived neurotrophic factor (BDNF), which is released due to nerve injury, is known to promote the natural healing of injured nerves. It is often observed that damage of mandibular canal induces local sclerotic changes in alveolar bone. We reported that peripheral nerve injury promotes the local production of BDNF; therefore, it was possible to hypothesize that peripheral nerve injury affects sclerotic changes in the alveolar bone. This study aimed to evaluate the effect of BDNF on osteogenesis using in vitro osteoblast-lineage cell culture and an in vivo rat osteotomy model...

PURPOSE: Bone defects of the inferior mandibular border (osseous inferior border defects) can cause unesthetic postoperative outcomes after bilateral sagittal split osteotomy (BSSO). The aim of this study was to estimate the frequency of osseous inferior border defects after BSSO and to identify risk factors for this complication. MATERIALS AND METHODS: This retrospective study included consecutive patients who underwent BSSO for mandibular retrognathia. The primary outcome was the presence/absence of osseous inferior border defects...

To explore the techniques for mandibular reconstruction with composite free flaps and their outcomes, we systematically reviewed reports published between 1990 and 2015. A total of 9499 mandibular defects were reconstructed with 6178 fibular, 1380 iliac crest, 1127 composite radial, 709 scapular, 63 serratus anterior and rib, 32 metatarsal, and 10 lateral arm flaps including humerus. The failure rate was higher for the iliac crest (6.2%, 66/1059) than for fibular, radial, and scapular flaps combined (3.4%, 202/6018) (p<0...

Surgery-first approach (SFA) has been a paradigm shift in the field of orthognathic surgery. Majority of the published cases that have been managed by this approach are of skeletal class III. This communication describes a patient of 18-year-old male diagnosed with skeletal class II malocclusion due to mandibular retognathism. He was managed with SFA and was using skeletal anchorage system to prevent postsurgical relapse. Bilateral saggital split ramus osteotomy was carried out to achieve the mandibular advancement of 7 mm...

Mandibular prognathism is usually treated with mandibular setback surgery. However, this approach reduces the pharyngeal airway space, and can aggravate obstructive phenomena in patients with obstructive sleep apnea (OSA). While maxillary expansion is known to lead to an increase in the pharyngeal airway volume (PAS), its effect on the PAS in mandibular setback surgery has not yet been reported. The authors report a surgical approach with maxillary expansion in 2 patients with mandibular prognathism that was accompanied by OSA: maxillary midsagittal expansion with minimum maxillary advancement and minor mandibular setback without mandibular anterior segmental osteotomy (ASO) or major mandibular setback with mandibular ASO...

Mandibular dislocation occurs when the condylar head glides out of the glenoid fossa with the condyle positioned in such a way that its posterior articulating surface lying ahead of the articular eminence. Recurrent mandibular dislocation is relatively uncommon. Patient is extremely distressed and goes through a lot of discomfort. Varied etiologies have been cited in the literature, such as keeping the mouth wide open for long periods of time during dental procedures, yawning, laughing, traumatic injuries to the mandible, psychiatric disturbances, and certain drugs...

There is too much individual patient variation in mandibular anatomy for any single described genioglossus advancement technique to be used consistently. Virtual surgical planning allows surgeons to design genioglossus osteotomy that captures the structures of interest. Intraoperative osteotomy and positioning guides mitigate known risks of the procedure while maximizing the reproducibility and efficacy of the procedure. In this report, we demonstrate the protocol step by step as it had been used on 10 patients, and we highlight 3 clinical scenarios that exemplify its utility...

Pierre Robin sequence (formerly a syndrome) is named after the French stomatologist who, in 1923 and 1934, described the problems associated with micrognathia in newborn. It comprises mandibular micrognathia, U-shaped cleft palate, and glossoptosis. The typical symptoms are hypoxaemia, noisy breathing, snoring, stridor, cyanosis, bradycardia, feeding difficulties, and failure to thrive. Distraction osteogenesis has recently been considered as a surgical option for early intervention to lengthen the mandible and relieve respiratory problems...

We report on the successful treatment of a 32-year-old woman with condylar hyperplasia and severe mandibular crowding. In addition, her maxilla was canted to the right, her mandibular midline and chin point deviated to the left, and her maxillary canines were missing. The treatment plan included (1) aligning and leveling the teeth in both arches, (2) correcting overbite and overjet, (3) performing LeFort I osteotomy and bilateral split osteotomies, and (4) correcting the malocclusion postsurgically. The orthodontic treatment was performed with custom lingual braces and clear brackets, and virtual surgical planning techniques were used to plan the orthognathic surgery...

Square face or prominent mandibular angle is a major concern in Asian women. In class III patients, mandibular setback may lead to a wider lower face that is not preferred in Asian culture. In order to achieve better aesthetic outcomes, simultaneous mandibular contouring to reduce the width of the lower face is required for some patients. This article details the authors' procedures modified from Hunsuck techniques of sagittal split osteotomy. This modified Hunsuck technique provides an alternative option to obtain a desirable mandibular outline...

The aim of this study was to compare the accuracy of linear measurements of the distance between the mandibular cortical bone and the mandibular canal using 64-detector multi-slice computed tomography (MSCT) and cone beam computed tomography (CBCT). It was sought to evaluate the reliability of these examinations in detecting the mandibular canal for use in bilateral sagittal split osteotomy (BSSO) planning. Eight dry human mandibles were studied. Three sites, corresponding to the lingula, the angle, and the body of the mandible, were selected...

PURPOSE: Originally introduced for mandibular reconstruction more than 40 years ago, the sternoclavicular graft (SCG) has gained widespread popularity for the reconstruction of the ramus-condyle unit (RCU) owing to its anatomic and histological likeness to the normal mandibular condyle. Conventional longitudinal osteotomy design for its harvest has been fraught with considerable complications at the donor site including fracture clavicle and major neurovascular injury. In an attempt to alleviate these ill effects, a new technique for procuring the sternoclavicular graft is presented...
