“…Gagan Mehta and Shadab Mohammad conducted a study on 20 cases and reported that there did occur resorption of the coronoid in most of the cases. However, that did not change mandibular function and occlusion [34].…”

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.

“…[19][20][21] In addition, cheek scaring is recognized as the main factor contributing to intermaxillary contracture. 11,14,22,23 Here, we not only reconstructed the unilateral condylar process, but also performed occlusion reconstruction and released the cicatricial contracture on the lower mandible margin. This contributed greatly to maintenance of the morphology and function of the TMJ in both the uninjured side and reconstructed side.…”

“…7,8 Recently, autogenous coronoid process grafts have been recognized as an ideal option for condylar reconstruction, due to the suitable shape and thickness of the coronoid process, its accessibility, and the satisfactory postsurgical results. 9–14 However, the success of the surgery relies on the accuracy of the deformity diagnosis and the presurgical planning. It is generally agreed that computer-aided design/computer-aided manufacturing (CAD/CAM) can assist in the surgical correction of tissue defects, repositioning of dislocated fragments, and the shaping of bone asymmetry.…”

Purpose: This study proposes a high-precision surgical technique that combines both computer-aided design/computer-aided manufacturing (CAD/CAM) and the screw-track transfer technique for condylar and occlusal reconstruction. Materials and methods: A 43-year-old male patient with facial asymmetry, limited mouth opening, and malocclusion underwent condylar and occlusal reconstruction surgery. An autogenous cor-onoid process graft was performed by combining CAD/CAM and the screw-track transfer technique. Results: The surgical plan was transformed successfully from preoperative virtual surgical planning to actual surgery; this was confirmed by merging the postoperative computed tomography images with the preoperative three-dimensional surgical design. The patient recovered well and had better occlusion and facial symmetry, as well as an increased degree of mouth opening post-surgery. No complications were observed. Conclusions: CAD/CAM combined with the screw-track transfer technique is a precise and feasible method that can be applied to autogenous coronoid process grafts. This approach can be used to reconstruct the condylar process and achieve a good occlusal relationship.

“…[1][2][3][4][5] Condylar compromise warranting reconstruction can occur following traumatic injuries, infection, tumor resection, radiation necrosis, or prior condylar surgery. 2,3,[6][7][8][9][10][11][12][13] Presentations of the aforementioned may include unilateral or bilateral involvement and, in either case, can cause significant malocclusion with the potential for long-term arthralgia, trismus, and other problems if not appropriately managed.…”

“…Ankylosis of the mandibular condyle is an unfortunately common pathology most often following trauma or a significant, untreated, chronic infection. 2,3, 10,14 Ankylosis results in bony or fibrous adhesions of the condyle, 14 yielding overall failure of the condyle to promote growth in younger patients and possibly resulting in disfigurement 4 as well as crippling joint function overall. Mandibular tumors may involve the condyle and surrounding soft tissue and include but are not limited to squamous cell carcinoma, osteomas, chondrosarcoma, and multiple myeloma.…”

Reconstruction of the Mandibular Condyle

The mandibular condyle is an integral structure in the temporomandibular joint (TMJ) serving not only as the hinge point for mandibular opening, but also facilitating mandibular growth and contributing to facial aesthetics. Significant compromise of the TMJ can be debilitating functionally, psychologically, and aesthetically. Reconstruction of the mandibular condyle is rarely straightforward. Multiple considerations must be accounted for when preparing for condylar reconstruction such as ensuring eradication of all chronically diseased or infected bone, proving clear oncologic margins following tumor resection, or achieving stability of the surrounding architecture in the setting of a traumatic injury. Today, there is not one single gold-standard reconstructive method or material; ongoing investigation and innovation continue to improve and transform condylar reconstruction. Herein, we review methods of condylar reconstruction focusing on autologous and alloplastic materials, surgical techniques, and recent technological advances.
