Functional and Aesthetic Outcomes of Asymmetric Dorsal Preservation for Correction of I-Shaped Crooked Nose Deformity.

Objective: The study was designed to evaluate the effectiveness of the asymmetric dorsal preservation technique for correcting I-shaped crooked nose deformity (CND).

Methods: Patients with I-shaped CND who underwent asymmetric dorsal preservation in the period from September 2020 to September 2021 were included in this retrospective study. The Rhinomanometry and Standardized Cosmesis and Health Nasal Outcomes Survey (SCHNOS) was used to assess the outcomes. Deviation angle (DA) measurements were used to evaluate the degree of crookedness. The results were recorded both preoperatively and 12 months postoperatively.

Results: Twenty-three patients were included in the study. Total nasal airflow and long-side nasal airflow were significantly higher 12 months postoperatively (p=0.001 each). Total nasal resistance, long-side nasal resistance, SCHNOS scores and DA measurements were significantly lower 12 months postoperatively (p<0.001 each).

Conclusion: Asymmetric dorsal preservation is a successful alternative technique for correcting I-shaped CND and achieving optimal aesthetic and functional outcomes.
