Outcome-based Comparative Study to Examine the Correction of Columella Deformitiesfollowing Rhinoplasty

Area of Science:

• Plastic Surgery
• Otolaryngology
• Facial Plastic Surgery

Background:

• The columella, a key facial feature, is often underrepresented in rhinoplasty outcome assessments.
• Standardized methods for columellar correction in rhinoplasty are lacking.

Purpose of the Study:

• To evaluate the effectiveness of columellar correction following rhinoplasty.
• To compare outcomes between open and endonasal rhinoplasty approaches for columellar correction.

Main Methods:

• Retrospective analysis of 65 rhinoplasty patients divided into open (15) and endonasal (50) groups.
• Assessment of columellar correction using Rohrich and Liu classification and Gunter's distance.
• Comparison of final outcomes focusing on columellar correction between the two surgical approaches.

Main Results:

• The endonasal group demonstrated a significantly higher overall incidence of columellar correction (90%) compared to the open group (67%) (P=0.043).
• A greater reduction in nasal axis-columella distance was observed in the endonasal group (98%) versus the open group (80%) (P=0.036).
• Quantitative analysis revealed a significantly greater overall reduction in nasal axis-columella distance with the endonasal approach (P<0.001).

Conclusions:

• While no single standard exists, identifying columellar deformities and the need for correction is crucial.
• Both open and endonasal rhinoplasty approaches can achieve satisfactory columellar correction.
• The endonasal approach may offer advantages in achieving greater columellar correction and reduction of nasal axis-columella distance.
