In 16 human face dissections under the operative microscope, the authors recall the classical anatomy of perioral muscles. Instead of the 3 muscles around the nostrils, they prefer to discern two layers: deep and superficial. The subnasal region can similarly be dissociated. Resuming the commissural node study they insist upon the peculiar role of the platysma muscle and its expansions, and upon the tight imbrication of buccinator and orbicularis oris muscles.
