RESUMO
The aim of the present study was to describe a variation of the anomalous nasi muscle in relation to the surrounding structures. The anomalous nasi muscle was found in the left face of a 40-year-old female during dissection. The anomalous nasi muscle lay on the lateral side of the nose, and it originated from the frontal process of the maxilla. The origin of the anomalous nasi muscle was located medial to the middle part of the levator labii superioris alaeque nasi muscle. It ascended superomedially to blend with the deep and lateral fibers of the superficial layer of the procerus below the level of the medial palpebral ligament. The length and width of the anomalous nasi muscle were 11.9 mm and 2.8 mm, respectively. This report demonstrated a variation of the anomalous nasi muscle, which will be helpful for understating the nasal movements and nasal wrinkles.
