Abstract
With their close anatomical relationship, the temporomandibular joint (TMJ), mandibular ramus, skull base, ear, and infratemporal fossa make up a complex structure that may collectively be referred to as the ‘TMJ and adjacent structures complex’ (TASC). This study presents the neoplasms that may be encountered in the TASC region and their classification, which may be useful for the surgical treatment. Data of 1022 consecutive patients treated with resection of TASC neoplasms from May 2000 to October 2022 were reviewed. Pathology outcomes were classified according to the World Health Organization classification and Bone Tumors (Dorfman and Czerniak). Extent of the lesions was analysed based on imaging modalities. Ten tissue origins were observed. Synovial lesions accounted for the highest proportion of pathologies (56.0%). Regarding their biological behaviour, the lesions could be divided into pseudotumours (12.8%), benign tumours (28.4%), intermediate tumours (57.0%), or malignant tumours (1.8%). All lesions originated from one of four sites: lesions intrinsic to the TMJ (91.5%), extending from adjacent structures (7.7%), distant metastatic spread (0.4%), and multiple general foci (0.4%). In conclusion, it is hoped that knowledge of the histopathological and biological features will facilitate the surgical treatment of these pathologies in a rational, minimally invasive, and functional manner.
期刊介绍:
The International Journal of Oral & Maxillofacial Surgery is one of the leading journals in oral and maxillofacial surgery in the world. The Journal publishes papers of the highest scientific merit and widest possible scope on work in oral and maxillofacial surgery and supporting specialties.
The Journal is divided into sections, ensuring every aspect of oral and maxillofacial surgery is covered fully through a range of invited review articles, leading clinical and research articles, technical notes, abstracts, case reports and others. The sections include:
• Congenital and craniofacial deformities
• Orthognathic Surgery/Aesthetic facial surgery
• Trauma
• TMJ disorders
• Head and neck oncology
• Reconstructive surgery
• Implantology/Dentoalveolar surgery
• Clinical Pathology
• Oral Medicine
• Research and emerging technologies.
