Prominent mandibular angleostectomy of the lateral cortex
Abstract
Many surgical techniques have been applied toward
correcting the prominent mandibular angle.
One of the most popular methods is mandibular
angle ostectomy. However, gross asymmetry, mandibular
condylar fracture, and unnatural contouring
of the mandibular angle are frequent consequences.
Therefore, we perform ostectomy of the
lateral cortex around the mandibular angle in patients
with wide and squared lower faces. Seventeen
female patients with ages ranging from 23 to
35 years underwent surgery. Ostectomy of the lateral
cortex of the mandible and mandible angle ostectomy
were performed in five patients (group I).
Ostectomy of the lateral cortex only was performed
in the remaining 12 patients (group II). The followup
period ranged from 1 to 5 years. Postoperatively,
the bigonial distance was effectively reduced in
both groups (group I, mean 13 mm; group II, mean
12 mm). Compared with group I, the gonial angle
and mandibular plane-sella-nasion angle were
within normal ranges in group II. We therefore conclude
that the ostectomy of the lateral cortex alone
allows the reduction to be achieved without changing
the angle of the mandible itself. Moreover, although
the resection of the mandibular angle was
not performed, the contour of mandibular angle became
soft, giving a more natural appearance.
Key Words: Prominent mandibular angle, ostectomy
