Measurements are classified as belonging to the alveolar process (A) and its subdivisions, the incisor (In) or molar (Mo) alveolus, or to the ascending ramus
(M) and its subdivisions, the coronoid process (Cr), the condyloid process (Cn), the angular process (Ag), or the masseteric region (Ms).
Peripheral osteoma of the mandibular ascending ramus
CT scan took, showed an ill-defined radiolucent lesion extending from the body of mandible to ascending ramus
of mandible (Fig.
Both subtypes usually occur in the body of the mandible and in its ascending ramus
The mandibular angle is formed by the intersection of the inferior rim of the body and the posterior rim of the ascending ramus
Various literature also have shown that about 80% of tumors occur in mandible, of which, 70% arise in the molar region and ascending ramus
, 20% in the premolar region, except for desmoplastic ameloblastoma which occurs most commonly in anterior region of maxilla.
Enlarged exeresis of the recurrent lesion was performed, including removal of the ascending ramus
of the mandible and the skin of the parotid area.
