Abstract
Maxillofacial deformations and malocclusions are common pathology that leads to severe functional and aesthetic disturbance. Etiological factors are trauma, genetic disorders, and hormonal imbalance. One of the rare and underexplored forms of congenital growth disorders are hemimandibular growth abnormalities as unilateral condylar hyperactivity, hemifacial elongation, condylar hypoplasia. Unilateral condylar hyperactivity (UCH) is a self-limiting pathology of mandibular condylar bone tissue overgrowth, leading to functional and aesthetic maxillofacial disturbance. The aim of the study was to identify the pathological features of hemimandibular growth abnormalities. We performed diagnostics and treatment of 35 patients (7 male, 28 female) aged from 16 to 37 years with condylar hyper- and hypoplasia. In case of unilateral condylar hyperplasia symptoms we performed high partial condyleectomy as the first step of treatment. In all the patients temporo-mandibular joint function was restored and facial aesthetic was improved as a result of treatment. According to histological features we found the materials from all patients to be divided into two groups: without pronounced continued growth and with signs of enchondral osteohistogenesis. Histological features of the pathological process were detailed in each group.
