“…Active physical therapy is imperative during the immediate postoperative period and should continue for at least 1 year to improve functional outcomes and prevent recurrent ankylosis. 11,23,24 Transport DO outperforms conventional approaches, such as costochondral grafting, with superior mandibular range of motion, increased maximal interincisor opening, and reduced relapse on early follow-up. 22 Though long-term follow-up studies are lacking, one study demonstrated significant reankylosis at follow-up times ranging from 16 to 92 months.…”

“…22 Transport DO of the mandible begins via a preauricular approach to access the TMJ. 11,23,24 Following resection of the ankylotic mass, a temporalis myofascial pedicled flap is transferred over to line the joint to prevent a bony connection between the mandible and the cranial base. 23,24 Ipsilateral coronoidectomy is also performed to avoid contact interference during mastication.…”

“…22,23 Dysarthria, feeding difficulties, and airway obstruction are longterm complications attributable to untreated TMJ ankylosis. 22,24 Numerous surgical options exist for TMJ ankylosis including gap arthroplasty, interpositional arthroplasty, costochondral grafting, and more recently, transport DO. 22 Transport DO of the mandible begins via a preauricular approach to access the TMJ.…”

Distraction Osteogenesis: Mandible and Maxilla

et al. 2021

Mandibular and maxillary deformities commonly require surgical intervention. Prior to distraction osteogenesis, traditional modalities involving single-staged translocation and rigid fixation were used to correct these craniofacial anomalies. Distraction osteogenesis has evolved as a compelling alternative for treating aesthetic and functional dentofacial defects. The process of distraction osteogenesis involves three phases—latency, activation, and consolidation—which allow for appropriate translation of the affected craniofacial skeleton. This review will cover the role of distraction for managing congenital and acquired deformities of the mandible and maxilla. This novel technique can be performed at numerous anatomical sites along the craniofacial skeleton to treat a variety of anomalies, which serves as a testament to its adaptability and efficacy. Importantly, distraction osteogenesis also has the ability to simultaneously increase bone length and the overlying soft tissue envelope. This advantage results in larger advancements with reduced relapse rates and improved patient satisfaction. While complications remain a concern, it stands to reason that the measurable benefits observed underscore the power and versatility of distraction osteogenesis.

The purpose of this chapter is to inculcate a newer, deeper understanding of TMJ Ankylosis– both from the pathological as well as the clinical view point. Newer classifications may now determine surgical procedures. Interpositional materials may not be just soft tissues interposed between the cut ends, but also hard tissues forming the new Ramus Condyle Unit (RCU). Facial deformity may be recognized to be as important as inability to open the mouth; more so, if accompanied by Obstructive sleep apnea (OSA). Multi-staged treatment plans of release first followed by asymmetry correction may be replaced by single staged joint replacement & total facial aesthetic as well as functional rehabilitation. Finally, the importance of unfavorable events in TMJ Ankylosis surgery may be recognized, which would lead to better results in terms of treatment goals, i.e. to restore joint function, improve facial appearance & airway issues, correct malocclusion & re-establish harmony between the TMJ, the face and the teeth.
