Purpose
Botulinum toxin type A (Botox; Allergan, Inc., Irvine, Calif) is widely used for facial rejuvenation and many other medical indications. It induces chemodenervation through its action on the presynaptic neuron, preventing release of acetylcholine, which leads to functional denervation of striated muscle for 2 to 6 months after injection. The use of botulinum toxin injection to reduce the facial scar is logical because this could reduce the tensile distracting force of the upper lip caused by the orbicularis oris muscle pull. Tollefson has demonstrate that botulinum toxin injection has decrease lip tension after primary lip repair in 3 children at 3-6 months of age The main aim of this randomized trial is to compare whether post-operative peri-surgical-injection of botulinum toxin into bilateral orbicularis oris muscles can improve scar formation for both primary and secondary cleft lip surgery.

- Vancouver Scar scale [ Time Frame: 6 month ] [ Designated as safety issue: Yes ]Vancouver scar scale measures pigmentation, vascularity, pliability and scar height on the postoperative 6 month F/U.
- Ultrasonography scar measurement [ Time Frame: 6 month ] [ Designated as safety issue: Yes ]On the 6th mo follow up, ultrasonography to measure the scar width will be performed.
- Photographic measurement [ Time Frame: 6 month ] [ Designated as safety issue: Yes ]The scar width of the patient's picture at 6 month after surgery will be measured using photoshop CS3 extended. One ruler will be placed on the patient's lip before taken the photo. Then the scar width could be measured.

Experimental: study group I
For primary lip surgery, immediately after primary lip repair will received botulinum toxin injection (1-2U/kg, at 25U/mL) into the bilateral aberrant oriented orbicularis ocuris muscle via 4 superficial injection site
|
Drug: Botulinum Toxin Type A
1-2U/kg, at 25U/mL, into the bilateral aberrant oriented orbicularis ocuris muscle via 4 superficial injection site; only once after surgery. No additional injection is needed
Other Name: Botox ( Allergan, Inc., Irvine, Calif)

|
Experimental: Study Group II
For revision lip surgery, immediately after revision lip surgery 3 injection of 2.5U of botulinum toxin with a distance of 0.5 cm from each injection and operative wound are injected over both sides of upper lip in a adult on the operation room.
|
Drug: Botulinum Type A
b. Study group II: For revision lip surgery, immediately after revision lip surgery 3 injection of 2.5U of botulinum toxin with a distance of 0.5 cm from each injection and operative wound are injected over both sides of upper lip in a adult on the operation room just after surgery. (total dosage injected 15U)
Other Name: Botox ( Allergan, Inc., Irvine, Calif)
