“…These observations were in accordance with the findings of Douglas, Burton, and Smith,[12] who reported that intraoral appliances have had advantages over extraoral devices by not only reducing or eliminating the problems of facial scarring caused by transcutaneous pins, but also by avoiding the emotional and cosmetic disadvantages of an extraoral appliance. However, intraoral devices are somewhat difficult to place and their removal could be as difficult as the initial placement.…”

Introduction:Management of mandibular deformities is challenging. Distraction osteogenesis is a relatively new technique with promising results.Materials and Methods:We selected 12 patients. The osteotomy site decided was proximal to the antegonial notch. Latency time was five to seven days. Consolidation period was eight weeks in eleven cases and six weeks in one case.Results:In all the patients, appreciable lengthening of mandible was achieved.Discussion:The greatest advantage of distraction osteogenesis is growth of soft tissue along with the growth of hard tissue. This increases post operative stability

“…A distraction devices is used to induce bone growth in the site of deformity (1). Long-term stability of DO has not been well documented, and some studies have found cases of instability and recurrence (2)(3)(4)(5). Therefore, some authors have attempted to accelerate bone maturation and to improve the physical properties of lengthened bone (6)(7)(8).…”

Objectives: This study evaluated the action of low level laser therapy (LLLT) on the percentage of newly formed bone in rabbit mandibles that underwent distraction osteogenesis (DO). Study design: Ten rabbits underwent bone lengthening according to the following protocol: Latency -3 days; Activation -7 days 0.7 mm/d; and Consolidation -10 days. The control group was composed of 4 rabbits. The experimental group, composed of 6 rabbits, received infrared GaAlAs LLLT (λ=830 nm, P=40 mW) according to the following protocol: point dose of 10 J/cm2 applied directly on the bone site that underwent DO during bone consolidation at 48-hour intervals. Results: The percentage of newly formed bone was greater in the LLLT group (57.89%) than in the control group (46.75%) (p=0.006). Conclusion: The results suggest that LLLT had a positive effect on the percentage of newly formed bone. Betterquality bone sites may allow early removal of the osteogenic distractors, thus shortening total treatment time.

Temporomandibular joint (TMJ) ankylosis is characterized by the formation of bone or fibrous adhesion of the anatomic joint components, which replaces the normal articulation and limitation of mouth opening. Early surgical intervention is considered as a treatment procedure to release the joint ankylosis and to maintain the function of the joint. Longstanding temporomandibular joint ankylosis which starts during the active growth period in early childhood resulting in facial asymmetry. Thus, the importance of the evaluation for the facial asymmetries and unfavorable remodeling of the mandible has to be considered during the initial treatment planning. Further operations, either osteotomies or distraction osteogenesis, are required for the treatment of maxillofacial deformities. The present study reports a case of unilateral TMJ ankylosis treated by interpositional arthroplasty prior to distraction osteogenesis for the treatment of mandibular secondary deformity. Various treatment procedures and timing protocols are reviewed and discussed.
