Some individuals inadvertently flare their nostrils while speaking.

Anatomic Considerations

The dilator nasalis muscle is the lower portion of the nasalis muscle and attaches to the alar cartilage. Contraction of the dilator nasalis muscle results in alar flaring. This muscle lies superficial to the lateral crura of the lower lateral cartilage.

Injection Technique

Topical anesthesia may be used; however, this single injection usually can be tolerated without anesthesia. One injection point is used per side. Approximately 5 BU or 15 DU are used per side. Inject into the immediate subdermal tissue, with care being taken to avoid the alar cartilage.
