Pediatric mandibular reconstruction after benign tumor ablation using a vascularized fibular flap.
This study evaluated the aesthetic and functional outcomes of vascularized fibular flaps used for pediatric mandibular reconstruction. Six pediatric patients ranging in age from 12 to 15 years underwent mandibular reconstruction using a vascularized fibula flap with a skin paddle, after benign tumor ablation. All of the flap transfers were successful, and there were no complications. ⋯ The aesthetic and functional outcomes were normal. No patient had recurrence. A vascularized fibular flap is a very reliable method for reconstructing the pediatric mandible after benign tumor ablation.

Carotid-cavernous fistulas (CCFs) are anomalous communications between the carotid arterial system and the venous cavernous sinus. They can arise because of spontaneous or trauma causes. Most caroticocavernous fistulas are of spontaneous origin and unknown etiology. ⋯ Treatment by endovascular transarterial embolization with electrolytically detachable coils is a very effective method for CCF with good outcomes. Carotid-cavernous fistulas have been rarely reported after craniofacial surgery and are uncommon pathologies in otolaryngology practice. In this study, we report a 40-year-old woman with CCF secondary to blunt trauma of functional endoscopic sinus surgery.

Fronto-orbital advancement and remodeling for craniosynostosis is extensive surgery and is associated with potential risks; the most significant of these is blood loss. We prospectively studied 116 consecutive patients undergoing fronto-orbital advancement by the same surgical team for a 5-year 6-month period to determine what factors are associated with blood loss and transfusion of blood products. The data collected on the calvarial sutures involved were whether the patient had a diagnosed syndrome, the age at operation, the length of the operation, the estimated blood volume lost during the perioperative course, the number of units of packed cells transfused (donor exposures), and the use of other blood products. ⋯ Other blood products were given in 28% of the cases. There was significantly greater blood loss in those patients with recognized craniofacial syndromes, pansynostosis, an operating time longer than 5 hours, and an age of 18 months or younger at operation. The use of other blood products was associated with those patients losing a blood volume higher than the mean.

A variety of etiologies may result in functional and aesthetic deficiencies requiring orbital reconstruction. Fractures of the zygomaticomaxillary complex in the acute stage are frequently accompanied by sensory disturbances of the zygomatic nerve (ZN). The purpose of the current study was to describe the anatomic and topographic landmarks of the ZN in 18 adult human cadavers regarding the localization and dimensions in the orbit. ⋯ The mean (SD) distance between the orbital opening of the ZFN and the infraorbital margin of the orbit was 13.04. (3.21) mm. A detailed knowledge of the ZN's passage in the orbit is necessary for a surgeon while performing maxillofacial surgery. If these measurements are taken into account, there will be little surgical risk, and this will be helpful in identifying the extent of the operative field.
