Abstract

Objectives: During inhalation through the nose, the weakness of
lateral cartilage may cause the collapse of nasal vestibule and sidewall,
causing the complaint of difficult breathing through the nose. We aimed to
support the lateral cartilage with a square edged strut to resolve this
problem.

Methods: We described a technique in 8 cases (5 males, 3
females). In this technique the lateral cartilage is semi wrapped from the underside to a square edged strut, and
arched to outside with an open approach rhinoplasty. As it was only a physical
support and did not create a new canting up through the skin, we named this
maneuver as pseudodome technique.

Results:
All patients experienced relief of symptoms and no complications observed. The
reinforcement effect of the strut was effective in preventing collapse of the
nasal alar sidewall as well as did not cause contour irregularities.

Conclusions:
Pseudodome technique can be performed
for acquired or congenital nasal sidewall collapse caused by lower lateral
cartilage structural weaknesses successfully.
