Nasal Reconstruction: Defects that Cross Anatomical Subunits

Area of Science:

• Plastic Surgery
• Facial Anatomy
• Reconstructive Surgery

Background:

• The nose's aesthetic and functional roles are critical.
• Understanding nasal biomechanics, framework, and aesthetic subunits is essential for reconstruction.
• Nasal subunits include paired ala, soft tissue facets, sidewalls, and unpaired dorsum, tip, and columella.

Purpose of the Study:

• To discuss approaches for nasal reconstruction using the aesthetic subunit principle.
• To provide technical pearls for various nasal defects.
• To emphasize adapting the subunit principle and combining techniques for optimal outcomes.

Main Methods:

• Discussion of reconstructive algorithms and techniques.
• Application of the aesthetic subunit principle in practice.
• Focus on creating inconspicuous scar lines with "straight lines and sharp corners".

Main Results:

• The subunit principle aids in planning reconstructions, especially for convex subunits like the nasal tip and alar lobule.
• Adapting the subunit principle and combining techniques are crucial for defects crossing subunits.
• The approach focuses on meticulous scar placement within existing nasal contours.

Conclusions:

• The aesthetic subunit principle is a valuable framework for nasal reconstruction.
• Understanding subunit anatomy and applying the principle leads to improved functional and aesthetic outcomes.
• Technical pearls enhance the execution of reconstructions, minimizing visible scarring.
