Simultaneous genial distraction and interposition arthroplasty for management of sleep apnoea associated with temporomandibular joint ankylosis

Impact of Mandibular Distraction Osteogenesis on the Oropharyngeal Airway in Adult Patients with Obstructive Sleep Apnea Secondary to Retroglossal Airway Obstruction

“…The magnitude of advancement that can be achieved and the predictability of outcome make MDO the treatment of choice over conventional osteotomies in adult cases of OSAS [3-8, 10, 11, 17] genial advancement with hyoid myotomy [18,19] and suspension, and genial distraction [20] are the alternate options that have been reported in the literature to improve the retroglossal airway patency. MDO has been our choice of treatment in these patients as we can achieve better control over the proximal and distal segments with MDO than with osteotomies.…”

A novel step osteotomy for correction of hemifacial microsomia – A case report

“…Distractional bone augmentation of the mandible bypassing the tooth-bearing segment was earlier reported by Gunaseelan et al, 9 who performed an extended genioplasty up to the mandibular first molar with a step modification in the region of the mental foramen. This segment was then distracted by means of an external pinfixated distraction device.…”

Primary mandibular distraction for management of nocturnal desaturations secondary to temporomandibular joint (TMJ) ankylosis

“…retruded mandible and micrognathia in these patients create a narrowing of the oro-pharyngeal space with mechanical obstruction to respiration, more so in supine position and during sleep. This process forms complex syndrome of apnoeic episodes with significant reduction in the mean oxygen saturation levels during sleep and secondary cardiac and respiratory problems [1,3,4].…”

“…Mandibular distraction has been used successfully to manage the facial deformities associated with TMJ ankylosis [1,[8][9][10][11]. However the simultaneous use of mandibular distraction with ankylosis release has significant disadvantages: (1) improper outcome of distraction due to unpredictable vector management and (2) physical interference of the distraction process, to active post-operative physiotherapy after ankylosis release [1,8,11].…”

“…This condition involving the fusion of the mandible and the temporal bone gives rise to a myriad of deformities of the facial skeleton. The features presented include hypomobility of the mandible, retrogenia, micrognathia, dental malocclusion, change in the cant of the maxillary occlusal plane, airway embarrassment and recurrent upper airway tract infections [1,2]. The presence of …”
