“…The absence of the elastic fibres as described by Wong, Weinberg & Symington (1985) in foetuses is not in accordance with our observations since these fibres were present in all portions of the disc in the three groups studied. Our, results confirm those of Griffin & Sharpe (1962)'and Griffin etal.…”

summary The articular disc of the temporomandibular joint was studied in a foetuses and children group (GI), a dentate group of adults (GII) and an edentulous, elderly group of humans (GIII) by light microscopy. The main, constituent bundles of type I collagen fibres are stratified and are orientated sagittally, transversely and obliquely in the middle portion of the disc. In the thick, posterior portion, transverse bundles constitute the main feature. In the anterior portion of the disc, the fibres are sagittally and obliquely orientated. Type III collagen fibres, intermingled with type I collagen fibres are present in all groups. The disc is cellular in nature in foetuses and children, becoming more fibrous with age. Chondroid cells are observed in all portions of the discs in groups GII and GIII. Elastic fibres are numerous in GI discs and decrease in number in the disc with age. These fibres lie parallel to the collagen fibres in all three portions of the three groups.

“…These structures along with the tensor veli palatini are innervated by V3 through the otic ganglion, which innervates the masticatory muscles coming from the mesoderm of the first branchial arch. (Baume, 1962;Furstman, 1963;Misurya, 1976;Thilander et al, 1976;Wong et al, 1985;Ohta et al, 1993;Perry et al, ;Sadler, 1998;Schames et al, 2002). Myrhaug (1964) reasoned that the ossicular chain and the middle ear muscles belong embryologically to the chewing system and that after this they become and serve as the hearing sense.…”

SUMMARY:For many years otic symptoms have been closely observed in TMD clinical practice. This review includes trials that meet eligibility criteria in the field of otic symptoms diagnosed and treated by a stomatognathic focal point. The aim is centered on the implications of the debated cause-effect connection between otic symptoms and TMD offering a probable bond between the TMJ, ear and adjacent structures. The rationalization is based on an embryological and anatomical approach that offers explanations on the otic pathogenic mechanisms symptoms interconnected with TMD. The accompanying reciprocity among disciplines of odontology and otolaryngology is brought together by TMD and otic referred mutual symptomatology as is showed in multiple trials. This research is an attempt that targets the integration of these two health specialties in the diagnosis and treatment of this type of population.

“…During development, it is thought that the lateral pterygoid muscle maintains a close relationship with the disc of the temporomandibular joint (Wong et al 1985 ;Merida-Velasco et al 1993). However, it has been suggested that the disc formation is independent of the muscle development (Baume, 1962 ;Baume & Holz, 1972 ;Van der Linden et al 1987 ;O $ g, u$ tecenToller & Juniper, 1993).…”

Positional relationships between the masticatory muscles and their innervating nerves with special reference to the lateral pterygoid and the midmedial and discotemporal muscle bundles of temporalis

For an accurate assessment of jaw movement, it is crucial to understand the comprehensive formation of the masticatory muscles with special reference to the relationship to the disc of the temporomandibular joint. Detailed dissection was performed on 26 head halves of 14 Japanese cadavers in order to obtain precise anatomical information of the positional relationships between the masticatory muscles and the branches of the mandibular nerve. After complete removal of the bony elements, the midmedial muscle bundle in all specimens and the discotemporal muscle bundle in 6 specimens, derivatives of the temporalis, which insert into the disc were observed. On the anterior area of the articular capsule and the disc of the temporomandibular joint, the upper head of the lateral pterygoid, the midmedial muscle bundle of temporalis and the discotemporal bundle of temporalis were attached mediolaterally, and in 3 specimens the posterosuperior margin of the zygomaticomandibularis was attached to the anterolateral area of the disc. It is suggested that these muscles and muscle bundles contribute to various mandibular movements. Although various patterns of the positional relationships between the muscles and muscle bundles and the their innervating nerves are observed in the present study, relative positional relationships of the muscles and muscle bundles and of nerves of the mandibular nerve are consistent. A possible scheme of the developmental formation of the masticatory muscles based on the findings of the positional relationships between the muscles and the nerves is presented.
