Summary
This study presents a less invasive external surgical approach for suprahyoid myotomy, reducing surgical stress and operating time compared to traditional methods for specific orthodontic patients.
Area of Science:
- Oral and Maxillofacial Surgery
- Orthodontics
- Surgical Techniques
Background:
- Suprahyoid myotomy is sometimes performed with sagittal split advancement for Class II malocclusion and open bite.
- Traditional methods include the Steinhauser technique (degloving incision) or Allison method.
- Genioplasty is not always required, necessitating alternative myotomy approaches.
Purpose of the Study:
- To present a modified suprahyoid myotomy technique via a small submental skin incision.
- To highlight the advantages of this external approach over existing methods.
Main Methods:
- Suprahyoid myotomy performed through a small submental skin incision.
- This external approach is utilized when genioplasty is not indicated.
Main Results:
- The submental incision method results in less surgical stress.
- Operating time is shorter compared to the Steinhauser technique.
- Reduced risk of major genioglossus muscle detachment compared to the Allison method.
Conclusions:
- An external suprahyoid myotomy is a viable and advantageous alternative.
- This technique offers reduced morbidity and improved efficiency for select patients.
- It provides a safer option for suprahyoid muscle detachment when genioplasty is not planned.
