Background and Objectives: Correction of deviated nose is considered one of the most difficult and serious surgical operations in rhinoplasty. The correction of bony deviation, in particular, requires osteotomy. Although there are individual differences in the shapes or features of bony deviations of each patient, the techniques of osteotomy are limited. Therefore, for proper correction of bony deviation, it is necessary to set up a precise pre-surgical plan.
Subjects and Method: We categorized 187 patients with bony deviated nose into 5 types based on the analysis of preoperative nasal bone 3D computer tomography, and studied surgical method for each type.
Results: Of 187 patients, 92 (49%) patients are categorized into type I, 62 (36%) patients into type II, 12 (6%) patients into type III, 2 (1%) patients into type IVa, 7 (4%) patients into type IVb and 7 (4%) patients into type V. Only did eight patients (5%) undergo revision surgery due to unsuccessful outcomes. Major complications like infection, abscess, arteriovenous fistula, epiphora, and saddle deformation did not occur at all.
Conclusion: Preoperative planning under the analysis and categorization using 3D CT is considered helpful for the precise and individualized surgery in corrective rhinoplasty.
