In this video, we explore the anatomy of the nasal muscles — small but significant structures involved in facial expression, nasal movement, and function. These muscles play important roles in both cosmetic and functional nasal surgery (like rhinoplasty and reconstructive procedures).

Key Nasal Muscles Covered:
Nasalis Muscle
Largest nasal muscle

Has two parts: Transverse part and Alar part

Function: Compresses or dilates the nostrils, helps in nasal airflow and expressions.

Procerus Muscle
Located between the eyebrows

Function: Pulls the skin between the eyebrows downward, contributing to frowning and transverse lines over the nose bridge.

Depressor Septi Nasi
Connects the upper lip to the nasal septum

Function: Pulls the nasal tip downward, especially during smiling — important in rhinoplasty to control nasal tip dynamics.

Levator Labii Superioris Alaeque Nasi
Runs alongside the nose from the upper lip to the inner eye area

Function: Elevates the upper lip and dilates the nostril — known for its role in “snarl” expression.


Clinical Relevance:

These muscles are considered during:

Rhinoplasty (for nasal tip control, alar base modification)

Botox treatments for nasal flaring or bunny lines

Functional nasal surgery involving nasal valve area

Facial reanimation surgeries


Understanding nasal musculature is key for surgeons, anatomists, and aesthetic practitioners aiming for precise results in both cosmetic and reconstructive facial procedures.
