Abstract

Botulinum neurotoxin (BoNT) injection for the treating plunged nose, post-rhinopasty and hyaluronic filler migration is common procedures in clinical settings. However, the lack of thorough anatomical understanding makes it difficult to locate the nose region muscles. The anatomical considerations concerned with BoNT injection into the nasalis, levator labii superioris alaeque, and depressor septi nasi muscles were reviewed in this study. The injection spots have been presented for the nasalis, levator labii superioris alaeque, and depressor septi nasi muscles, with the recommended injection technique for each muscle. We have suggested the ideal injection sites in association with outer anatomical landmarks of the nose region. Moreover, these proposals would support a more accurate procedure of BoNT injection in relieving plunged nose, preventing post-rhinoplasty deviation, and migration of the hyaluronic acid filler.
