Poster 1235, Language: EnglishFirdoose, Nyer
The mandible or submaxilla is a 'U' shaped pivotal structure, considering the attachment of the muscles of mastication with relation to mastication itself. The coronoid process is a variably shaped beak-like projection at the anterosuperior aspect of the ramus, the anterior border of which is convex and continuous with the ramus. Posteriorly, the border is slightly concave and contributes to the mandibular notch. The entire border of the coronoid along with the medial surface provides attachment for the temporalis muscle. Previous studies have shown that the size and shape of the coronoid are co-related to the bite force required by an individual and is dependent upon the mechanical force acting upon it during development. However, little is known about the developmental program leading to the specification of the process. The relative shape and size of the coronoid process varies considerably across individuals. The author in this poster aims to present his unique discovery of 'Coronoid Foramina' bilaterally along with bilateral accessory foramina over the lateral aspect of the mandibular ramus, which has never been seen or documented in literature to date.
