Area of Science:

  • Plastic Surgery
  • Anatomy
  • Surgical Techniques

Background:

  • Tip rhinoplasty is a complex procedure requiring precise surgical access.
  • The sublabial approach offers a potential alternative for accessing nasal structures.

Purpose of the Study:

  • To evaluate the utility of the sublabial approach for tip rhinoplasty maneuvers in a cadaver model.
  • To identify graft types suitable for sublabial placement and assess translatability to human subjects.

Main Methods:

  • Dissection of ten fresh-preserved cadavers.
  • Standard rhinoplasty views captured via photography.
  • Evaluation of sublabial approach for various rhinoplasty techniques.

Main Results:

  • Successful division of depressor septi muscle in 100% of cadavers.
  • Improved nasal projection and rotation with columellar strut and shield grafts in 100% of cadavers.
  • Correction of caudal septum using the swinging door technique in 60% of cadavers.

Conclusions:

  • The sublabial approach is effective for performing multiple tip rhinoplasty techniques in cadavers.
  • This approach shows promise for clinical application in human subjects.
