ABSTRACT Context: Surgery for the release of temporomandibular joint (TMJ) ankylosis is a commonly performed procedure. Various interposition materials have been tried with varying success rates. However, none of these procedures attempt to recreate the architecture of the joint as the glenoid surface is usually left raw. Aims: We aimed to use a vascularised cartilage flap and to line the raw surface of the bone to recreate the articular surface of the joint. Settings and Design: There is a rich blood supply in the region of the helical root, based on branches from the Superficial Temporal Artery (STA), which enables the harvest of vascularised cartilage from the helical root for use in the temporomandibular joint. Materials and Methods: Two cases, one adult and the other a child, of unilateral ankylosis were operated upon using this additional technique. The adult patient had a bony segment excised along with a vascularised cartilage flap for lining the glenoid. The child was managed with an interposition graft of costochondral cartilage following the release of the ankylosis, in addition to the vascularised cartilage flap for lining the glenoid. Results: The postoperative mouth opening was good in both the cases with significant reduction in pain. However, the long-term results of this procedure are yet to be ascertained. Conclusions: The vascularised cartilage flap as an additional interposition material in temporomandibular joint surgery enables early and painless mouth-opening with good short-term results. The potential applicability of this flap in various pathologies of the temporomandibular joint is enormous.

ABSTRACTPurposePediatric temporomandibular joint (TMJ) reconstruction occurs as a result of acquired, developmental, and/or congenital conditions. Current pediatric reconstruction options are limited. The aim of this project was to develop a proof of principle porcine model for a load bearing, customized 3-dimensional (3D) printed and BMP2-coated scaffold implanted in a pedicled (temporal) flap as a regenerative approach to pediatric TMJ mandibular condyle reconstruction.Materials and MethodsScaffolds were custom designed and 3D printed based on porcine computed tomography and absorbed with BMP2. Two operations occured: (1) implantation of scaffold in temporalis muscle to establish vascularity, and six weeks later, (2) unilateral condylectomy and rotation of the vascularized scaffold (with preservation of superficial temporal artery) onto mandibular ramus defect and secured with titanium screws. At 6 months post-implantation, the pigs were sacrified. The experimental side (muscle-scaffold) and the control side (unoperated condyle) were individually harvested at 6 months and evaluated by clinical, mechanical, radiographic, and qualitative/histologic methods.ResultsScaffolds maintained physical properties similar in appearance to unoperated condyles. The vascularized scaffolds had bone formation at edges and adjacent to scaffold-bone interface. New bone was visible in scaffold. Condyle height on the reconstructed side was 68% and 78% of the control side. Reconstructed condyle stiffness was between 20% and 45% of the control side.ConclusionIn our porcine model, customized 3D printed TMJ scaffolds impregnanted with BMP2 and implanted in and pedicled on temporalis muscle has the ability to (1) reconstruct a TMJ defect model, (2) maintain appropriate condylar height and upper airway diameter, and (3) generate new bone, without impacting functional outcomes.

Minimally Invasive Procedure

Temporomandibular joint (TMJ) arthroscopy is considered a safe, minimally invasive procedure for the treatment of certain TMJ derangements. However, as TMJ arthroscopy is being popularized, more complications are being reported. Though exceedingly rare, arteriovenous fistula (AVF) can occur. We describe a case of superficial temporal artery (STA) fistula formation successfully treated with coil embolization.
