Maintaining the space between the mandibular ramus segments during bilateral sagittal split osteotomy does not influence the stability.

Background/purpose: Three-dimensional computer-assisted orthognathic surgery allows to simulate the space between the mandibular ramus segments, i.e. intersegmental gap, for the correction of facial asymmetry.

Primary Rhinoplasty Does Not Interfere with Nasal Growth: A Long-Term Three-Dimensional Morphometric Outcome Study in Patients with Unilateral Cleft.

Background: Primary rhinoplasty has not been universally adopted because the potential for nasal growth impairment remains an unsolved issue in cleft care. This study's purpose was to assess the long-term effects of primary rhinoplasty performed by a single surgeon in a cohort of patients with a unilateral cleft lip nose deformity.

Methods: Three-dimensional nasal morphometric measurements (linear, angular, proportional, surface area, and volume) were collected from consecutive patients (cleft group, n = 52; mean age, 19 ± 1 year) who had undergone primary rhinoplasty with the use of the Noordhoff approach between 1995 and 2002 and reached skeletal maturity.
