Nasal Tip Vascularization and Its Application for Columellar Reconstruction.

Area of Science:

• Plastic Surgery
• Anatomy
• Reconstructive Surgery

Background:

• Vascular anatomy of the nose is well-documented for reconstruction.
• Anatomical variations of nasal arteries and perforators are described.
• A specific nasal tip perforator's utility for columellar reconstruction is less explored.

Purpose of the Study:

• To analyze a nasal tip artery perforator.
• To describe its anatomical characteristics.
• To evaluate its clinical application in columellar reconstruction.

Main Methods:

• Descriptive anatomical study using intraoperative vascular dissection.
• Investigated the nasal tip perforator artery during nasal tip flap surgery.
• Observational study of patients undergoing columellar repair (2013-2018).

Main Results:

• The nasal tip artery was consistently identified in all dissections.
• Its location and trajectory were documented.
• Columellar dimensions in operated patients showed significant differences compared to controls.

Conclusions:

• The nasal tip artery's presence and trajectory are consistent.
• The nasal tip flap, based on this perforator, is effective for columellar repair.
• Preservation of this artery ensures safe nasal tip flap elevation and may improve blood supply.
