Sonoanatomy of the Nasal Ala for Botulinum Neurotoxin Injection.

ABSTRACT:

Background

The nasal ala region significantly affects facial aesthetics and function. Botulinum toxin injections may enhance nasal appearance, but their precise impact on underlying muscles remains unexplored. Understanding the muscular anatomy and behavior in this area is crucial for optimizing toxin application and achieving desired outcomes.

Objective

This study aimed to ultrasonographically assess and characterize the muscular architecture of the nasal ala region in 32 participants, with the primary objective of delineating the specific muscles involved in nasal aesthetics.

Methods and materials

This cross-sectional study included 32 participants (15 females and 17 males, aged 20-65) with no history of nasal surgery or botulinum toxin injections in the nasal regio
