Abstract (original English)
Introduction Infection, improper dissection, trauma, or excessive tension on the columellar closure can result in necrosis of the columella. Maneuvers such as advancing the base of the columella anteriorly or using a Silastic healing chamber can help prevent columellar necrosis. Objective Reconstruction of columellar defects is complex and may involve the recruitment of upper lip tissue, composite grafting, or the use of local or regional flaps. Structural grafting using autologous cartilage provides the necessary structural support to achieve a long-term esthetic and functional outcome. Methods Chart review and data analysis. Results All cases resulted in successful reconstruction. Two complications were noted in 34 cases. Conclusions Avoiding tension on the columellar closure can help to prevent necrosis. Columellar reconstruction may require Silastic healing chamber, grafts or flaps. In the author's experience, nanofat and hyperbaric oxygen are frequently used to maximize outcomes in prevention and management of columellar necrosis.
What this study does not prove
- • This study does not prove SVF is an approved treatment or a replacement for standard care.
- • Without an adequate control group, treatment effects cannot be separated from other factors.
