ABSTRACT
The purpose of the study was to find the occurrence of the tumour in the mandible in relation to age, sex, site, clinical, radiological presentation and to compare treatment modalities and their success
The study was carried out on 32 patients withAmeloblastoma of mandible during the period 1996 to 2003, who reported at the Maxillo Facial unit of Khyber College of Dentistry, University Campus Peshawar. Aproforma was designed to record information about these patients withAmeloblastoma of mandible in relation to age, sex, site, clinical and radiological findings. The diagnosis was confirmed by histopathology in each case. The treatment was decided and done depending on clinical and radiological findings and extension of tumour. Patients were followed up to nine years and on every review clinical and radiological examination was done and any recurrences found were treated accordingly
The age range was from 10 years to greater than 51 years with mean age 33.9 years. There were 8 males [25%] and 24 females [75%] with male to female ratio of 1:3. The most common site waspremolar to ramus region 28.1% [9] where as tumour extending from molar to ramus region was in 21.8% [7]. Clinically 15 [46.8%] patients presented with swelling without pain. In 10 [31.1%] patients there was swelling along with loosening of teeth. Five patients [15.6%] had swelling and pain together. There were 2 [6.2%] patients who had a chance finding on x-ray. Radiologically there were 19 [59.3%] patients with multi locular radiolucency and 9 [28.1%] patients with uni cystic appearance. Four patients [12.5%] had the typical honeycomb appearance. Excision of the tumour along with bone skimming was done in 14[43.7%] patients. Wide excision of the tumour along with healthy bone margins sparing lower mandibular border was done in 8 [25%] patients. Segmental resection with reconstruction was done in only 4 [12.5%] patients. Hemimandibulectomy with reconstruction was done in 6 [18.7%] patients. In review and follow up only 25 patients out of 32 patients came regularly
There were 3 [9.3%] patients with recurrence were in the group where only excision and bone skimming was done. There were also 2 [6.2%] patients who had recurrence and belonged to the group of treatment where wide excision along with healthy margins was made but lower mandibular border was spared
It is concluded from our study that whatever the size of tumour its complete excision is necessary
