Does the Botulinum Toxin Affect the Philtral Length in Primary Repair of Unilateral Cleft Lip?
Background: Repair of cleft lip deformities requires careful planning to create functional and aesthetically
pleasing upper lip contour. Cleft lip scar has a serious impact on appearance. Many factors affect the
formation of a scar, as continuous muscle contraction. The botulinum toxin has been used recently to
minimize facial scarring by decreasing wound tension as it produce a localized muscle weakness. The
injection of botulinum toxin into lip muscles reduces the continuous muscle contraction and skin tension
and creates a good condition for wound healing and reduction of the formation of hypertrophic lip scar
after lip repair. We suggest that preoperative botulinum toxin injection into the orbicularis oris muscle of
wide cleft lip patients improves the outcome of cleft lip repair. Methods: In this study, 20 patients with
complete unilateral cleft lip were divided into two groups, the first group was injected with botulinum toxin
(10 patients) and the other group control (10 patients) was injected with saline. Injection was done with
insulin syringe 7 days before primary lip repair using modified Millard cheiloplasty. The patient’s scars
were assessed using photography and scar length and width measurements after 3 and 6 months. Results:
The difference between the two groups was statistically significant after 3 and 6 months. These results show
that botulinum toxin had a better effect in decreasing the scar width and increasing the philtral length.
Conclusions: Botulinum toxin injection into the orbicularis oris muscle in unilateral complete cleft lip
preoperatively shows significant improvement in the cheiloplasty scar.
Key words: Botulinum toxin, Cleft lip repair, Philtral length.
