The aim of this study was to compare arthroscopic assisted release of lateral pterygoid muscle versus scarification of retrodiscal tissues in the treatment of internal derangement of temporomandibular joint.
A prospective, interventional, randomized, comparative clinical study that was carried out on patients with TMJ anterior disc displacement diagnosed via adequate clinical examination and MRI findings. They were divided randomly into two equal groups: Group one was treated by arthroscopic assisted release of the lateral pterygoid muscle. Group two was treated by arthroscopic assisted scarification of the retrodiscal tissues. All patients were followed up via clinical and MRI.
Clinical parameters regarding jaw opening, lateral excursion and joint pain were improved. All patients reestablished normal position of the anteriorly displaced disc confirmed by postoperative MRI.
Arthroscopic assisted release of lateral pterygoid and scarification of retrodiscal tissues have some potential to be one of the methods for management of anteriorly displaced discs not responding to the conservative treatment.
