Abstract. – Temporomandibular joint disorders (TMD) is a collective term used to describe pathologic conditions involving temporomandibular joint (TMJ), masticatory muscles and associated structures.
Common related complaints include local pain, limited mouth opening and TMJ noises whereas symptoms often associated to TMD with debated pathogenesis enclose earache, headaches, tinnitus and trigeminal-like symptoms such as atypical orofacial pain.
In particular, TMD trigeminal associated symptoms are intricate, difficult to treat and exert a great impact on everyday life of the patients thus invoking a complex multidisciplinary treatment.
In this paper, the authors analyze the anatomic and topographic relationships between the mandibular branch of the trigeminal nerve and the medial aspect of the TMJ capsule in 8 fresh adult cadavers thus resuming a pathologic relationship between atypical trigeminal symptoms and TMD.
