Summary
The butterfly graft for internal nasal valve reconstruction alters nasal tip width by a mean of 6.4%. Supratip projection changes varied, indicating potential cosmetic effects alongside functional improvement.
Area of Science:
- Rhinology
- Plastic Surgery
- Otolaryngology
Background:
- Internal nasal valve (INV) dysfunction significantly impacts nasal airflow.
- The auricular cartilage butterfly graft is an effective technique for INV reconstruction.
- Concerns exist regarding the graft's potential to alter nasal tip aesthetics.
Purpose of the Study:
- To evaluate postoperative changes in nasal tip width and supratip projection after butterfly grafting.
- To assess the cosmetic impact of the butterfly graft in INV reconstruction.
Main Methods:
- Retrospective review of 157 patients undergoing butterfly grafting (2005-2009).
- Analysis of preoperative and 3-month postoperative photographs.
- Measurement of nasal tip width (frontal view) and supratip projection (lateral view).
Main Results:
- Mean change in nasal tip width was 6.4% (range -10.2% to +15.7%).
- Mean change in supratip projection was 8.5% (range -23.4% to +15.0%).
- Variability in supratip projection changes suggests potential cosmetic alterations.
Conclusions:
- The butterfly graft causes a mean 6.4% change in nasal tip width.
- Supratip projection changes exhibit significant variability, possibly due to intended cosmetic modifications.
- The clinical significance of the 6.4% tip width change depends on individual patient factors and degree of nasal dysfunction.
