Summary
This study introduces new aesthetic subunits for nasal reconstruction tailored to Oriental patients, improving outcomes for defects caused by trauma or tumors. The revised units and flap techniques enhance three-dimensional appearance and minimize visible scarring.
Area of Science:
- Plastic Surgery
- Otolaryngology
- Facial Reconstruction
Background:
- The aesthetic subunit principle is effective for nasal reconstruction but existing topographic subunits are often unsuitable for Oriental noses.
- Oriental noses differ from Caucasian noses, featuring a lower bridge, less prominent glabella, and less distinct underlying cartilage and bone structure.
- Previous reconstruction methods may not adequately address the unique anatomical characteristics of the Oriental nose, impacting aesthetic results.
Purpose of the Study:
- To devise and validate novel aesthetic subunits for nasal reconstruction specifically adapted for Oriental facial anatomy.
- To evaluate the efficacy of these new subunits and associated flap techniques in reconstructing moderate to severe nasal defects.
- To compare the outcomes of this modified approach with traditional methods, focusing on aesthetic and functional improvements.
Main Methods:
- Development of modified aesthetic subunits for the nose, including the glabella as an independent unit and omitting soft triangles.
- Utilization of specific flap techniques: V-Y advancement flap (glabella), forehead island flap (nasal dorsum/tip), nasolabial flap (ala), and malar flap (cheek).
- Application of the devised subunit principle and flap techniques in the reconstruction of nasal defects in 24 patients.
Main Results:
- Successful reconstruction in most patients, with suture lines strategically placed for inconspicuousness and trapdoor contraction enhancing 3D appearance.
- Minor complications included texture mismatch (forearm flap), web formation (Z-plasty revision), and need for defatting (forehead flap).
- The modified subunit approach effectively addressed nasal dorsum flatness and improved overall nasal aesthetics, particularly in Oriental patients.
Conclusions:
- The proposed aesthetic subunits and reconstruction techniques are well-suited for Oriental patients with nasal defects, offering significant aesthetic advantages.
- The method helps avoid nasal dorsum tenting and flatness by reconstructing the dorsum with side walls simultaneously.
- This approach provides a valuable alternative for nasal reconstruction, with potential applicability to some Caucasian patients as well.
