The anatomy of the facial musculature must be understood by orthodontists, whose main interest is the appearance of the teeth and periodontal tissue, because the behavior of perioral muscles critically influences the structure of a smile. Slowly relax and maintain one half of the teeth visibility. Structure The zygomaticus major muscle originates from the upper margin of the temporal process, part of the lateral surface of the zygomatic bone. Vascular supply to zygomaticus minor comes from the superior labial branch of facial artery. Among these, the LLS, the LLSAN, and the ZMi determine the amount of lip elevation that occurs during smiling. Our case report may serve as a reference for head and neck IMH in the ZMi, as it was successfully treated without nerve damage or muscle dysfunction. The injection dose of BTX that is used has been stated in a number of reports but differs among studies. Maintain this position for 10s.
