Area of Science:

  • Plastic Surgery
  • Otolaryngology
  • Facial Plastic Surgery

Background:

  • Dorsal hump reduction in rhinoplasty often necessitates septum resection.
  • Traditional methods have evolved with newer subdorsal approaches.

Purpose of the Study:

  • To review and compare various subdorsal flap techniques used in dorsal preservation rhinoplasty.
  • To understand the modifications and outcomes associated with these septal approaches.

Main Methods:

  • Review of literature on subdorsal flap techniques for rhinoplasty.
  • Description of modified subdorsal strip, Z-flap, intermediate septal strip, and Tetris concept.
  • Analysis of septal cuts for excision and mobilization of dorsal cartilaginous segments.

Main Results:

  • Multiple subdorsal flap techniques exist, including modified subdorsal strip, Z-flap, intermediate septal strip, and Tetris concept.
  • These techniques involve specific septal cuts to achieve dorsal flexion and lowering.
  • Outcomes data indicate satisfactory results for each approach, alongside noted limitations.

Conclusions:

  • Subdorsal flap techniques offer diverse strategies for dorsal hump removal in rhinoplasty.
  • Careful septal manipulation is key to successful dorsal flexion and lowering.
  • Ongoing data collection is vital for understanding the full potential and constraints of each method.
