The course of the inferior alveolar neurovascular canal in relation to sliding genioplasty.

The anterior course of the inferior alveolar neurovascular canal was determined in 52 hemimandibles using high-resolution radiographs. Significant variability was found in its course. It was noted that if the osteotomies for sliding genioplasty were performed at least 6 mm below the inferior border of the mental foramen, injury to the mental nerve would be reduced.

Recipient vessels for microvascular transplants in patients with hemifacial microsomia.

Hemifacial microsomia is a developmental abnormality involving structures derived from the first and second branchial arches. Microvascular transplants are increasingly being used to improve facial contour in patients with this condition. We have reviewed 9 patients with this abnormality to determine which recipient vessels have been used. In 6 patients, the facial vessels were located and used for flap revascularization. In 3 patients, the facial vessels could not be identified intraoperatively, and the occipital artery and a branch of the external jugular vein were used as recipient vessels. In this series of hemifacial microsomia patients, therefore, the facial vessels could not be located in 3 patients. We recommend that surgeons performing microsurgical transplants in cases of hemifacial microsomia be prepared to explore the external carotid and external jugular systems for recipient vessels.

Placement of the umbilicus in an abdominoplasty.

The location of the umbilicus was measured in 100 randomly selected non-obese subjects. It was found that a line drawn from the highest level of the crest of one ilium to the same point on the other side will transect the umbilicus in 96 percent of the subjects. This relationship can be of use during an abdominoplasty, when determining the location for the umbilicus.
