Area of Science:

  • Anatomy
  • Plastic Surgery
  • Craniofacial Morphology

Background:

  • The hyoid bone's role in cervicomental morphology is often overlooked.
  • Suprahyoid muscles significantly influence hyoid bone position.

Purpose of the Study:

  • To review the anatomy and function of the hyoid bone and suprahyoid muscles.
  • To evaluate a surgical technique for correcting caudal and anterior hyoid positions to improve neck contour.

Main Methods:

  • Analysis of cephalometric radiographs (cephaloxerograms) from 54 patients.
  • Surgical transection of specific suprahyoid muscles (anterior belly of digastric, geniohyoid, mylohyoid) in 16 patients.
  • Assessment of cervicomental contour improvement post-surgery.

Main Results:

  • A balanced neck typically has the hyoid bone at or above the Frankfort horizontal line passing through the menton.
  • Surgical correction resulted in cervicomental contour improvement in all 16 patients.
  • Improvement scores ranged from 1 to 5, with most patients showing significant positive outcomes.

Conclusions:

  • The position of the hyoid bone is crucial for cervicomental aesthetics.
  • Surgical relocation of the hyoid bone by transecting specific suprahyoid muscles is an effective method for improving neck contour.
  • The procedure demonstrates a high success rate with minimal complications.
