Selective Osteotomies to Correct Deviated Bony Vaults of Asian Noses.

Background: Standard osteotomies for the correction of deviated noses are bilateral and comprise a combination of medial and lateral osteotomy procedures. However, their uniform application to the small/delicate Asian bony vault is inappropriate and often results in suboptimal outcomes.

Objectives: This study describes how asymmetric bony pyramids were defined through 3-component analysis, which was then used to inform selective/individualized osteotomies.

Methods: Bony vault deviations were categorized after 3-component analysis in 117 patients seeking correction of a deviated nose. Selective osteotomies were applied accordingly. Pre- and postoperative photographs were compared and rated by 2 independent evaluators. Patients' subjective evaluations were also included.

Results: Selective osteotomies were possible in 79 (68%) out of 117 patients. Among the 79 study subjects, outcome ratings were excellent in 37 (47%), acceptable in 25 (32%), unsatisfactory in 8 (10%), and unspecified in 9 (11%). Unspecified cases aside, satisfactory correction was achieved in 88% (62/70 patients). Of the 54 patients who responded to telephone interviews, patient satisfaction was excellent in 43 (80%), improved in 10 (18.2%), and unchanged in 1 (1.8%). Follow-up of the 88% of patients with satisfactory correction showed a stable long-term outcome.

Conclusions: Each bony vault in deviated noses is different, and thus, its correction must be individualized for each patient and for each side. The protocol described herein achieves a controlled correction of deviated bony vault. Restoration of bony pyramid symmetry via current techniques is best suited to short Asian bony vaults, where additional structural needs from routine nasal augmentation/lengthening are required.
