Hemimandibular hyperplasia is a rare type of condylar hyperplasia which leads to facial asymmetry. Its surgical correction may be challenging since it usually requires complex mandibular osteotomies. Mandibular inferior border ostectomy is poorly described in the literature. The aim of this report is to present a new surgical technique guided by a customized surgical splint manufactured using computer-aided design/computer-aided manufacturing technology. Very good aesthetic results are achieved as it is very precise.

Evaluating Surgical Approaches for Hemimandibular Hyperplasia Associated with Osteochondroma: A Systematic Literature Review.

: Hemimandibular hyperplasia (HH) associated with osteochondroma presents complex challenges in maxillofacial surgery, including facial asymmetry, occlusal instability, and temporomandibular joint (TMJ) dysfunction. Surgical interventions vary widely in approach and outcomes, underscoring the need for a systematic evaluation of effectiveness. This systematic review assesses the effectiveness of surgical approaches for managing HH associated with osteochondroma, focusing on techniques including condylectomy, orthognathic surgery, distraction osteogenesis, total joint replacement (TJR), and genioplasty.

Objectives: Unilateral condylar hyperplasia (UCH), marked by progressive condylar growth, occurs between ages 11-30 with unclear etiology. This retrospective study aims to clarify the clinical, radiographic, and demographic features of UCH to improve its diagnosis and treatment.
Material And Methods: Data for all patients included in this study were retrieved from the archive.
Aim: Condylar hyperplasia (CH) is a progressive and deforming disease that modifies anatomy of the temporomandibular joint (TMJ) structures. This study aims to correlate the metabolic bone activity of the condyle measured by SPECT with the volumetry anatomic information from the condyle, fossa and joint space provided by CT images, in patients with CH in active and inactive forms.
Materials And Methods: A cross-sectional comparative study was performed with a set of 116 images from healthy and diagnosed CH patients to compare volumetric measures of the TMJ.

Growth disturbances of the temporomandibular Joint are characterized by mandibular asymmetry, sometimes with secondary maxillar disturbances. Although the clinical symptoms are sometimes quite severe, patients usually have no pain. There are several growth disturbances, but in this article we discuss three particular causes of facial asymmetry, namely hemimandibular growth defects; overdevelopment, underdevelopment and neoplasms of the mandibular joint.

A 34-year-old man presented with facial asymmetry and was diagnosed with left-sided hemimandibular hyperplasia. Orthognathic surgery and mandibular angle osteotomy combined with inferior alveolar nerve repositioning were performed with computer-aided design. The facial asymmetry was successfully corrected with acceptable cosmetic results.
