Objectives: The purpose of the present study was to critically evaluate the literature, describe the clinical and radiographic features of HD-SOD (hemimaxillofacial dysplasia/segmental odontomaxillary dysplasia), and describe one new case, involving a 12-year-old boy, with detailed radiological, clinical, and histologic characteristics.
Methods: Thirty-six cases published between 1987 and 2010, together with the present case, were evaluated according to criteria that included gender, age, location of the lesion, findings, and symptoms.
Results: We found that the lesion is discovered mainly in the first decade of life (71%), and has a male predilection (64%, 23/64). The maxillary alveolar process was affected unilaterally in all cases, with gingival and bone enlargement and facial asymmetry being constant findings. Missing premolars and skin manifestations were found to be common features.
Conclusions: New case reports should include clinical, radiographic, and histologic findings; follow-up reports; and treatment protocols to improve dentist and parent information regarding HD.
