Case Reports Comparative Study
Mandibular reconstruction in Goldenhar syndrome using temporalis muscle osteofascial flap.
Goldenhar syndrome is a well-known developmental anomaly of the maxillofacial skeleton and hemifacial soft tissue. Maxillofacial anomalies of that syndrome can be managed by a variety of means such as inlay- or onlay-applied nonvascularized bone grafts, vascularized osteocutaneous/osseous flaps, or distraction osteogenesis. Vascularized full-thickness calvarial bone grafting is an important option for mandibular reconstruction for cases in which, for one reason or another, other techniques are not available, not applicable, or have failed. ⋯ Sequential bone scintigraphies, performed to assess the vascularity of the grafts 1 week, 1 month, and 1 year after the operation, demonstrated the viability of transferred vascularized bone graft. The temporalis muscle osteofascial flap is a reliable method for mandibular reconstruction. It lessens the operative time, lessens surgical team labor, minimizes postoperative morbidity and discomfort, minimizes the hospital stay period, and minimizes financial expenses without renouncing the bone-healing capacity and increases aesthetic outcome by camouflaging the donor site scar in scalp and minimizing the facial scarring.

Patients with syndromic craniosynostosis are at risk for elevated intracranial pressure because of various physiologic and anatomic abnormalities. The aims of this study were to determine the prevalence of papilledema in syndromic craniosynostosis, to evaluate the results of the treatment, and to examine the risk factors. This is a retrospective study on 84 patients with Apert, Crouzon, or Pfeiffer syndrome. ⋯ The prevalence of papilledema in patients with Apert, Crouzon, or Pfeiffer syndrome is high, not only before cranial decompression but also after vault expansion. Annual fundoscopy is recommended to screen for papilledema. We consider that early decompressive surgery (within the first year of age) prevents the development of papilledema and, most likely, elevated intracranial pressure.

Palsy of the lingual nerve (LN) during third molar extractions, ramus osteotomies, anesthetic injections, procedures of orthognathic, preprosthetic, and periodontal surgery are important complications reported with varying frequency. The purpose of this study is to present quantitative data describing the position and shape of the LN in the third molar area. In the course of dissection, the LN was noted, as well as the furcation pattern, position, course, and anatomic relations under 2.5X loupe magnification in 21 adult male human cadavers. ⋯ The horizontal distance of the LN from the lingual plate of the mandible was greater in this study than in previous studies. This study provided measurable objective criteria for the relationship of LN in the third molar region. The knowledge of the relationship between the LN and third molar region is useful for the surgeon in avoiding unexpected complications.

Case Reports
Traumatic unilateral temporomandibular joint dislocation overlooked for more than two decades.
Forward dislocation of the temporomandibular joint commonly can be easily diagnosed and successfully reduced by manual repositioning. In this report, we discuss a rare case of prolonged temporomandibular dislocation that had persisted for more than 20 years because the otolaryngologist and dentist had missed the dislocation. ⋯ It is possible that strong pain and mouth-closing disability may gradually remit and only deviated mandibular prognathism like malocclusion may persist. Therefore, abnormal occlusion warrants careful attention to temporomandibular joint dislocation.

The aim of this study is to elucidate the nerve passage over the iliac crest shifted by skin retraction in harvesting iliac bone graft. A total of 44 iliac crests obtained of 22 nonembalmed Korean fresh cadavers were dissected (six males and 16 females; age range, 57-91 years). In A group (22) of "reposed skin," a skin incision was made from the anterior superior iliac spine (ASIS) to the highest level of iliac crest (HLIC). ⋯ An injuring rate of ilioinguinal nerve was almost the same between A group (13 branches, 59.1%) and B group (14 branches, 63.61%). P value is 0.760. In the procedure of harvesting iliac bone graft, it is suggested to make an incision on the skin retracted medially and on the anterior half site of ASIS to HLIC to avert an injury of superficial sensory nerves.
