“…When considering the radiographic aspects, the mandible was the commonest site of involvement in the analyzed cases and the unilocular aspect was predominant, which also corroborates the findings in the literature. 8,9,[11][12][13] The only multilocular case in the sample corresponded to an 18-year woman, with a 33 mm UAM located in the posterior region of the mandible associated with teeth #46 and #47.…”

BackgroundUnicystic ameloblastoma is an encapsulated odontogenic neoplasm with a single cyst cavity. The conservative or aggressive surgical approaches used to treat the tumor directly affect recurrence rates. However, there is a lack of a standard protocol that can guide its management.Study DesignWe retrospectively reviewed the clinicopathological findings and therapeutical procedures of 12 unicystic ameloblastoma cases treated by the same surgeon during the past 20 years.MethodsAll cases of unicystic ameloblastoma diagnosed by biopsy and treated by the same surgeon between 2002 and 2022 were reviewed. Eligibility criteria were patients with completely filled‐out charts containing the follow‐up period and confirmation of the diagnoses based on the microscopic findings of the whole excised specimens. Data collected were categorized into clinical, radiographic, histological, surgical, and recurrence aspects.ResultsThere was a female predilection (2:1), and ages ranged between 18 and 61 years (mean: 27.25, ±12.45). Almost all (92%) affected the posterior mandible. Radiographically, the mean length of the lesions was 46.14 mm ± 14.28 mm which 92% were unilocular and 8.3% multilocular. Root resorption (n = 7, 58%), tooth displacement (n = 9, 75%), and cortical perforation (n = 5, 42%) were also observed. The mural histological subtype corresponded to 9 (75%) of the cases. The same conservative protocol was performed in all cases. The follow‐up period ranged between 12 and 240 months (~62 ± 65) and recurrence occurred in only one patient (8%).ConclusionOur findings suggest a conservative approach should be the first option for unicystic ameloblastoma treatment, even for those with mural proliferation.
