Asymmetry is one of the most unusual and fascinating errors of human reproduction. A subtle asymmetric variation of the contralateral structures of the face occurs commonly in the general population, even in the absence of any local lesion or systemic conditions. Hemihypertrophy, congenital hemihypertrophy, hemimacrosomia, or partial gigantism are the terms used when the association of these changes with time or modifying circumstances such as trauma is missing. Meckel in 1822 gave the initial description, and the first report was by Wagner in 1839. This case report presents the case of a 20-year-old female with hemifacial hypertrophy, treated with “extended corpus angle V-line mandibular ostectomy” with modifications in armamentarium. Corrective procedure performed was in comparison to the contralateral side. Anterior half ostectomy, followed by posterior half ostectomy, was carried out with an oscillating saw, contra-angle handpiece, and curved chisel, respectively. Radiological assessment of the inferior alveolar nerve helped in planning the ostectomy and preservation of the nerve. Single-stage extended mandibular corpus-angle ostectomy has helped in accomplishing an esthetic correction.
