The dilator naris anterior and the alar part of the nasalis muscles are active in nasal valve regulation, while the procerus, the anomalous nasi, and the transverse part of the nasalis muscles do not affect the function of the nasal valve, because they are located above the nasal bone and the upper lateral cartilage.
