Arthroscopic anatomy of the anteromedial wall of the temporomandibular joint: Implications in articular disc displacement.

Numerous anatomical and imaging studies have established a close relation between disc displacement of the temporomandibular joint (TMJ) and the medial wall of the TMJ. These studies have revealed a direct association between disc displacement without reduction (DDWoR) and the occurrence of fatty degeneration within the superior fascicle of the lateral pterygoid muscle (SPLM). While the aetiology of this phenomenon remains unclear, it has been suggested that it stems from the interaction between this muscle fascicle and the bony surface of the medial wall of the joint.

Endoscopically assisted removal of ectopic teeth in the floor of the orbit. Case report and latest literature review.

Ectopic sinonasal third molar is a rare condition characterized by the aberrant position of the third molar in the maxillar sinus. The etiology of the teeth in the maxillary sinus is commonly associated to trauma and iatrogenic dental procedures. We present the clinical case of a 33-year-old man who presents an ectopic tooth in the right maxillary sinus, located in the orbital floor, who requires endoscopic control through a maxillary approach when performing the extraction.

Consensus Report and Recommendations on the Management of Late-stage Internal Derangement of the Temporomandibular Joint.

This report investigates late-stage internal derangement (ID) of the temporomandibular joint (TMJ) with the aim of establishing a more effective and personalized treatment protocol to improve patients' quality of life (QoL). A consensus was reached among maxillofacial surgeons specializing in LSID, based on a literature research and collective expert experience following the Delphi method. Consensus was considered to be achieved when a response received at least 80% of votes.

An exchange technique in temporomandibular joint (TMJ) arthroscopy to insert a larger operative cannula to facilitate advanced procedures.

The paper describes a modification of the surgical technique for temporomandibular joint arthroscopy, using an exchange guide to replace the 2.2 mm cannula with one of 2.9 mm to better facilitate osteoplasty of the medial wall.

Arthroscopic osteoplasty of the medial and anteromedial wall of temporomandibular joint: surgical technique and anatomical considerations.

The anterior displacement of the articular disc is the most frequent cause of pathological alterations in the TMJ. Although it is an extremely common pathology, there is no certainty about the aetiopathogenesis of this disease. The main aim of the present report is to describe new anatomical findings that could help clarifying the aetiopathogenesis of this disease and determine a typology of treatment based on the cause of the disease.
