The Appropriate Retractors for Genioplasty

Area of Science:

• Oral and Maxillofacial Surgery
• Surgical Innovation
• Biomedical Engineering

Background:

• Mental nerve (MN) injury is a frequent complication following genioplasty.
• Such injuries can lead to paresthesia or dysesthesia in the lower lip, chin, and mandibular incisor region.
• Protecting the MN and oral mucosa is crucial for patient safety and functional outcomes.

Purpose of the Study:

• To invent and validate specialized retractors designed to protect the mental nerve (MN) during genioplasty.
• To reduce the incidence of paresthesia and dysesthesia associated with genioplasty.
• To enhance the surgical visual field and improve operative efficiency.

Main Methods:

• Development and validation of novel retractors specifically for genioplasty procedures.
• Surgical application of the developed retractors to safeguard the mental nerve and oral mucosa.
• Evaluation of the retractors' effectiveness in preventing neurosensory disturbances.

Main Results:

• The developed retractors effectively protect the mental nerve (MN) and oral mucosa.
• The use of these retractors prevents paresthesia or dysesthesia in the lower lip, chin, and vestibular gingiva.
• Improved surgical visual field and enhanced operation efficiency were observed.
• The method demonstrated simplicity, safety, efficiency, and labor-saving benefits.

Conclusions:

• The newly invented retractors offer a safe and effective solution for preventing mental nerve (MN) injury during genioplasty.
• These retractors enhance surgical precision and efficiency while minimizing the risk of neurosensory complications.
• The innovation represents a significant advancement in genioplasty surgical techniques and patient safety.
