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. Clin Ter 2013; 164(2):e107-113.
