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).
A similar full-thickness incision which is used in sagittal split osteotomy was performed between ascending ramus and first molar for removal of the tumor (Figure 3).
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. Unicystic ameloblastoma is generally associated with a lower rate of postoperative recurrence than is the polycystic form.
Within the mandible, susceptible site is posterior body followed by condyle, angle, ascending ramus, coronoid process, anterior body and sigmoid notch in descending frequency.10
The mandibular angle is formed by the intersection of the inferior rim of the body and the posterior rim of the ascending ramus. The mandible houses the lower dentition, which in adults consists of 2 central and 2 lateral incisors, 2 canines, 2 first and 2 second premolars, and 3 sets of molars.
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.
