AB  - Coronoid process hyperplasia (CPH) is an uncommon disorder characterized by an 
      enlarged coronoid process impinging against the posterior aspect of the zygomatic 
      arch. Young male adults are usually affected, presenting with limited mouth 
      opening, which is typically painless and progressive in nature. The diagnosis of 
      true CPH is established by the findings of (1) uniform coronoid enlargement on 
      radiographic examination and (2) normal bone structure on histopathological 
      examination (i.e., the specimen should be free of any neoplastic growth, such as 
      the previously reported cases of coronoid osteomas, osteochondromas, or 
      exostoses). The treatment is mainly surgical, by means of a coronoidectomy. An 
      intraoral approach is mostly preferred for this procedure to avoid an external 
      scar. However, to avoid the drawbacks of this approach, such as limited exposure 
      and the risk of hematoma and subsequent fibrosis, an extraoral approach may be 
      indicated. This report describes a case of true unilateral CPH in a 17-year-old 
      boy who presented with progressive limited mouth opening in the absence of any 
      pain. Computed tomography (CT) demonstrated a uniformly enlarged right coronoid 
      process. A coronoidectomy was performed with the aid of endoscopic systems, 
      approaching via two short incisions in the temporal scalp. Histopathological 
      examination of the specimen demonstrated essentially a normal bony structure with 
      no evidence of a neoplasm. The authors present the endoscopically assisted 
      technique of coronoid process excision as an alternative method of surgical 
      treatment of CPH and any mass of the coronoid process in general. With this 
      method, the incision is much shorter than a conventional coronal incision and 
      thus morbidity is diminished considerably.
