Acute open callus manipulation: Clinical experience with a new surgical technique for solving old problems in distraction osteogenesis.

J Craniomaxillofac Surg 2018 Dec 7. Epub 2018 Dec 7.

Stomatology Department, São José Hospital, R. José António Serrano, Lisbon Portugal.

Background: Transport distraction osteogenesis is challenged as a potential alternative to free-flap reconstruction of segmental jaw defects due to its longer treatment time, vector control difficulties, need for additional bone-grafting, and problems creating a curvilinear shape. We propose a new technique of acute open callus manipulation and fixation (AOCMF), which addresses these challenges.

Methods: A retrospective analysis of all patients with jaw defects who underwent DO and AOCMF between 2006 and 2015 was performed. Read More

Resolution of obstructive sleep apnea after mandibular distraction osteogenesis in setting of delayed tongue-lip adhesion takedown: A case report.

Medicine (Baltimore) 2018 Oct;97(42):e12853

Department of Plastic Surgery, Children's Hospital Colorado, Aurora, CO.

Rationale: There is a high prevalence of obstructive sleep apnea (OSA) in patients with Pierre Robin sequence (PRS), and treatment approaches are highly variable. One approach is a temporary tongue-lip adhesion (TLA) that acts as a temporizing measure while the mandible continues to grow and is usually taken down at 1 year of age.

Patient Concerns: Side effects of prolonged tongue-lip adhesion and optimal workup and treatment of persistent OSA in the setting of a tongue-lip adhesion. Read More

Pre-arthroplastic mandibular distraction osteogenesis for the correction of OSA in TMJ ankylosis: a prospective observational study of 25 cases.

Oral Maxillofac Surg 2018 Dec 25;22(4):409-418. Epub 2018 Sep 25.

Department of Oral and Maxillofacial Surgery, Nair Hospital Dental College, Room no 107, A L Nair Road, Mumbai, Maharashtra, 400008, India.

Introduction: In severe TMJ ankylosis cases, the lack of growth of the mandible creates an anatomically narrow airway with a reduced pharyngeal airway space [PAS] which predisposes these patients towards obstructive apnoea [OSA]. There is evidence in the literature that such patients experience severe discomfort during physiotherapy if such airway abnormalities are not corrected prior to ankylosis release. This eventually leads to non-compliance towards physiotherapy and increases the risk of re-ankylosis. Read More

Treatment of Severe Maxillary Hypoplasia With Combined Orthodontics and Distraction Osteogenesis.

J Craniofac Surg 2018 Jun;29(4):970-972

Department of Orthodontics, Vita Salute, San Raffaele University.

Distraction osteogenesis (DO) is a technique that allows the generation of new bone in a gap between 2 vascularized bone surfaces in response to the application of graduated tensile stress across the bone gap.Distraction osteogenesis has become a routine treatment of choice to correct skeletal deformities and severe bone defects in the craniofacial complex over the past decade. Distraction osteogenesis has been successfully chosen in lengthening the maxilla and the mandible; in the maxilla and recently in the mandible, the jawbones have been distracted and widened transversely to relieve severe anterior dental crowding and transverse discrepancies between the dental arches.
