  • Title: Intraoral mandibular distraction osteogenesis in facial asymmetry patients with unilateral temporomandibular joint bony ankylosis.
    Author: Yoon HJ, Kim HG.
    Journal: Int J Oral Maxillofac Surg; 2002 Oct; 31(5):544-8. PubMed ID: 12418572.
    Abstract:
    Gap arthroplasty and costochondral rib bone graft are commonly performed by oral and maxillofacial surgeons to reconstruct the temporomandibular joint with ankylosis. However, unpredictable and unsatisfactory results such as re-ankylosis, growth disturbance, and facial asymmetry often occur. Even if the costochondral graft is successful, donor-site morbidity is inevitable. More recently, surgeons have become interested in distraction osteogenesis as a means of temporomandibular joint reconstruction. This case series presents the results of intraoral mandibular distraction osteogenesis and gap arthroplasty in two patients with facial asymmetry and unilateral temporomandibular joint bony ankylosis. Both patients had experienced failed gap arthroplasty and costochondral graft for the reconstruction of the temporomandibular joint. Distraction osteogenesis with gap arthroplasty proved successful in these two patients with follow-up of longer than 2 years.
