Subdorsal Flaps in Dorsal Preservation

In dorsal preservation rhinoplasty, resection of the septum is required to remove a hump. Modifications to the original immediate subdorsal strip excision of Goodale and Lothrop include the following sub-dorsal approaches: modified subdorsal strip method, Z-flap, intermediate septal strip, and Tetris concept. All of these subdorsal flap techniques are similar in using carefully designed septal cuts to excise and/or mobilize a dorsal cartilaginous segment for dorsal flexion and lowering. The growing body of outcomes data suggests satisfactory results and limitations of each of these septal approaches.
