Mandibular remodeling after bilateral sagittal split osteotomy for prognathism of the mandible.

Purpose: To describe the postoperative remodeling changes in the mandible after bilateral sagittal split osteotomy to correct mandibular prognathism.

Patients And Methods: Twenty patients who underwent bilateral sagittal split osteotomy for the correction of mandibular prognathism were studied for postoperative remodeling changes within the mandible. The 6-week, 1-year, and long-term postoperative cephalometric mandibular tracings of 12 patients were superimposed using the fixation wires as the stable reference points to demonstrate the specific locations of the intrabony remodeling.

Bilateral sagittal split osteotomy for correction of mandibular prognathism: long-term results.

Purpose: To identify the long-term maxillomandibular changes after surgical correction of mandibular prognathism using bilateral sagittal split osteotomy (BSSO).

Patients And Methods: Twenty patients who underwent BSSO to setback the mandible and had cephalometric radiographs taken preoperatively and postoperatively at 6 weeks, 1 year, and long-term follow-up (mean, 28 months). The cephalograms were traced and measured to determine the operative and postoperative changes.

Osseous regeneration after embolization of mandibular arteriovenous malformation.

A mandibular arteriovenous malformation (AVM) is rare, and unawareness of this condition can lead to catastrophic complications. Embolization is an effective means to treat these lesions. The osseous changes and long-term outcomes among the pediatric patients after embolization treatment remain unclear.

Outcome for traumatic optic neuropathy--surgical versus nonsurgical treatment.

This study was performed to identify factors that can affect the final outcome and to recognize the proper management for patients with traumatic optic neuropathy (TON). This retrospective study included 42 consecutive patients with TON after maxillofacial trauma. Megadose methylprednisolone was administered to all patients during the first 3 days after diagnosis.

Programmed database system at the Chang Gung Craniofacial Center: part II--digitizing photographs.

Background: The archival tools used for digital images in advertising are not to fulfill the clinic requisition and are just beginning to develop. The storage of a large amount of conventional photographic slides needs a lot of space and special conditions. In spite of special precautions, degradation of the slides still occurs.

Spontaneous bone regeneration of the mandible in an elderly patient: a case report and review of the literature.

Spontaneous bone regeneration is an unexpected phenomenon that may take place in large mandibular defects secondary to trauma and tumor resection. One explanation for this unusual healing course is that it may be derived from the mechanism of fracture healing. A review of the literature presents several factors that may influence this process, such as the presence of periosteum and bony fragments, mandibular stabilization, soft tissue protection, the presence of infection, and a young age.
