Overview
Depending on the extent of the tumor at the time of diagnosis, the prognosis may vary. However, the prognosis is generally regarded as poor/good/excellent.
Natural History, Complications, and Prognosis
Natural History
- In several cases the patients with ameloblastoma are asymptomatic.[1][2][3]
- Ameloblastoma most commonly diagnosed as an accidental finding on orthopantomography.
- The most common symptoms in patients with ameloblastoma are as following:
- Facial swelling
- Malocclusion
- loosening of teeth
- ILL-fitting dentures
- Periodontal diseases
- Oroantral fistulas and
- Nasal airway obstruction
- Ameloblastoma is regarded as a true neoplasm of enamel.
- Ameloblastoma described as unicentric, nonfunctional, intermittent in growth.
- Ameloblastoma is the second most common odontogenic neoplasm.
- Ameloblastoma histologically classified as six subtypes:
- Follicular subtype
- Plexiform subtype
- Acanthomatous subtype
- Granular subtype
- Desmoplastic subtype and
- Basilar subtype.
- Ameloblastoma most commonly affects mandible more than maxilla.
- Ameloblastomal progress as a slow growing, painless expansion of jaw
Complications
- Complications of ameloblastoma include the following:[4][5]
- The recurrence rate of these tumors is 25-30%.
Prognosis
- The prognosis of ameloblastoma was determined mainly by the method of surgical treatment, which means that patients receiving a radical treatment had a better prognosis than those who received a radical one. [6][7]
- It seemed that the best way for treating the ameloblastoma was extensive resection of the tumor with a wide region in the normal bone.
- In more than 50% patients receiving the conservative treatment had good prognosis without any recurrence.
- The biological behavior of the ameloblastoma was related to the radiographic appearance, and the multilocular type of ameloblastoma had a poor prognosis.
- Ameloblastoma which has a well-defined edge with sclerosis is thought to grow slowly, and the normal bone has a strong reaction to form the sclerosis edge, and the prognosis is good.
- Ameloblastomawith the ill-defined radiographic boundary, the tumor has the highest proliferative ability and poorest prognosis.
- Radical surgery should be used for the multicystic ameloblastoma to prevent the recurrence.
- The follicular ameloblastoma were thought to have a higher recurrence rate than unicystic or plexiform.[8]
