The nasal tip: a new dynamic structure

Area of Science:

• Anatomy
• Facial Plastic Surgery
• Rhinology

Background:

• Facial profile imperfections are a common concern for patients seeking aesthetic consultation.
• Etiologies are often attributed to skeletal or cartilaginous structures.
• A distinct muscular contribution to nasal and upper lip morphology has not been fully elucidated.

Purpose of the Study:

• To identify and describe a novel muscular structure contributing to facial profile.
• To elucidate the anatomical and functional characteristics of this muscle.
• To establish a classification system for related imperfections.

Main Methods:

• Detailed anatomical dissection and morphological description of the identified muscle.
• Analysis of its origin, insertion, and tendinous connections.
• Observation of its role in facial profile dynamics.

Main Results:

• Identification of the digastricus nasi-septi labialis, a muscle linking the nose to the upper lip.
• Description of its columellar and labial portions, joined by a central tendon acting as a pulley.
• Demonstration of independent or synchronous function of muscular portions, influencing profile.
• Establishment of a didactic classification (septum 0-III) based on severity.

Conclusions:

• The digastricus nasi-septi labialis is a distinct anatomical entity responsible for specific facial profile imperfections.
• Understanding this muscle's function is crucial for accurate diagnosis and treatment planning.
• The proposed classification aids in standardizing the assessment of these nasal and labial aesthetic concerns.
