**Core Concept**
Partial closure of the nose, also known as partial alar closure, is a surgical technique used to manage certain nasal conditions. The underlying principle involves modifying the nasal anatomy to improve airflow or reduce complications. This technique is often employed in cases of **nasal septal perforation** or **alar collapse**.
