BACKGROUND: Papillary cystadenoma is a rare benign epithelial tumor of the salivary gland, which is characterized by papillary structures and oncocytic cells with rich eosinophilic cytoplasm. We found only one case of papillary cystadenoma in nearly 700 cases of salivary gland tumors. Our case was initially mistaken for a tumor of the right temporomandibular joint (TMJ) capsule rather than of parotid gland origin. Preoperative magnetic resonance imaging (MRI) and computed tomography (CT) should be carefully studied, which allows for appropriate preoperative counseling and operative planning...

INTRODUCTION: Temporomandibular disorder (TMD) is considered the main cause of orofacial pain of non-dental origin, and a public health problem. The symptomatology is muscular and/or articular pain, restriction of the mandibular range of motion, and changes in the mandibular movement pattern. Due to its complexity there are already treatments using various forms of therapy. Photobiomodulation using light sources, such as low-level laser or light emitting diodes (LED), with different wavelengths, in a single or combined form, allows one more therapeutic resource to be explored...

BACKGROUND: Temple headaches are common, yet the anatomic etiology of headaches in this region is often confusing. One possible cause of temple headaches is dysfunction of the auriculotemporal nerve (ATN), a branch of the third division of the trigeminal nerve. However, the site of pain is often anterior to the described path of the ATN, and corresponds more closely to a portion of the path of a small branch of the second division of the trigeminal nerve called the zygomaticotemporal nerve (ZTN)...

The temporomandibular joint (TMJ) disc, a fibrocartilaginous structure between the mandible and temporal bone, is implicated in temporomandibular disorders (TMDs). TMDs symptomatically affect approximately 25% of the population; of which, 70% have internal derangement of the disc. Treatments lack efficiency, motivating novel therapies, including tissue-engineering toward TMJ disc regeneration. Recent developments in scaffold-based or scaffold-free approaches, cell sources, and biochemical and mechanical stimulation have resulted in constructs exhibiting native tissue mechanics...

Isaac Liau, Paul Sambrook, Andrew Cheng
Traumatic intracranial intrusions of the mandibular condyle are a rare injury pattern that carries significant morbid outcomes due to potential for neurological, otological, temporomandibular joint damage, or joint ankylosis. Treatment modalities involve either closed reduction, open approaches via transcranial or subtemporal approaches, or delayed total joint replacement. This paper presents a clinical report of a traumatic intracranial intrusion of the mandibular condyle treated with an endoscopically assisted preauricular approach to reconstruct the middle cranial fossa and temporomandibular articular disc...

Osseous choristoma is a rare entity in the oral and maxillofacial region. The most common site is the tongue, followed by the buccal mucosa. Osseous choristoma of the muscle is unusual and few cases have been described in the literature. No reports have described osseous choristoma arising on the medial side of the lateral pterygoid muscle. Herein, we report the first such case. A 61-year-old woman was referred to our facility for treatment of temporomandibular joint disorder. Computed tomography (CT) revealed two osseous lesions on the medial side of the lateral pterygoid muscle...

Disc displacement is a common disorder affecting the temporomandibular joint. According to previous publications, the displaced disc can be categorized into pure anterior displacement and rotational displacement (anteromedial and anterolateral). However, the technique of arthroscopy treatment has only been reported for patients with pure anterior disc displacement. In this study, an arthroscopic discopexy for rotational anterior disc displacement was developed and its effectiveness evaluated over 24 months of follow-up...
