Introduction. Muscles of the nose are active in facial movements both with the other facial muscles. An active depressor septi muscle (DSN) can accentuate a drooping nasal tip and shorten the upper lip on animation, especially during smiling. Paralysis of the DSN allows the tip of the nose to be lifted up.
Materials and Methods. Between January and June 2011 a double blinded, randomized study was performed on 40 patients for nasal defects as “plunging” tip. 20 patients underwent to Botulinum toxin injection (B), 20 patients were treated with placebo such as saline solution (S). Both aesthetic and functional results were evaluated using objective and subjective parameters at time 0, after 7, 15 and 30 days and values were compared using t Student test.
Results. S group results were not significant from an objective point of view. In botulinum group, patients showed an increase in columellar-lip distance. Satisfaction of the Group B patients was an average of 6.3 on VAS (range from 4 to 9). VAS mean values were studied with t-Student test and were found significant.
Discussion. Several authors recommend the incision of DSN muscle during rhinoplasty to correct the plunging tip. In patients with no needs for rhinoplasty this procedure is unnecessary and a quick and targeted injection of Botulinum toxin is the most convenient choice to improve aesthetic of the plunging tip.
