Overview
In several cases, the patients with ameloblastoma are asymptomatic. 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]
- In more than 50% patients receiving the conservative treatment had good prognosis without any recurrence.
- 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]
