This study maps the zygomaticofacial nerve (ZFN) skin area in Korean adults. Precise ZFN innervation zones are detailed for surgical planning in malar region reconstructions.
Area of Science:
- Anatomy
- Facial Nerves
- Dermatology
Background:
- The zygomaticofacial nerve (ZFN) plays a crucial role in facial sensation.
- Understanding its precise cutaneous distribution is vital for reconstructive and aesthetic surgery.
- Previous studies have provided limited data on ZFN innervation patterns in specific populations.
Purpose of the Study:
- To precisely elucidate the cutaneous distribution of the zygomaticofacial nerve (ZFN) in adult Koreans.
- To provide detailed anatomical data for surgical applications.
- To enhance understanding of facial nerve anatomy.
Main Methods:
- Dissection of 20 hemifaces from 10 adult Korean cadavers.
- Detailed mapping of the ZFN-innervated rectangular area.
- Measurement of the dimensions and central location of the ZFN distribution relative to facial landmarks.
Main Results:
- The ZFN-innervated area was consistently rectangular.
- Average dimensions of the rectangle were 18.8 x 15.8 mm.
- The center was located 17.3 mm laterally and 18.1 mm inferiorly from the lateral canthus.
Conclusions:
- Established precise anatomical boundaries for ZFN cutaneous innervation in Koreans.
- Data supports intraoral approaches for maloplasty and midface lifts.
- Knowledge of ZFN distribution aids in preventing nerve damage during facial procedures.
