What this trial studies

This interventional study gives a botulinum toxin A injection before performing a modified Millard rotation-advancement repair to see if reducing muscle tension around the lip improves scar appearance. Eligible participants are non-syndromic patients with mild to severe unilateral cleft lip, with or without cleft palate, who are fit for general anesthesia; patients with syndromic clefts or systemic disease are excluded. Outcomes will be measured by standardized clinical and photographic scar assessments during postoperative follow-up. The single-center trial is conducted at Mansoura University in Al Mansurah, Egypt.

Who should consider this trial

Good fit: Ideal candidates are non-syndromic patients with mild to severe unilateral cleft lip (with or without cleft palate) who are fit for general anesthesia and surgery.

Not a fit: Patients with syndromic cleft lip, significant systemic disease, or those unable to travel to the single study center are unlikely to be eligible or to benefit.

Why it matters

Potential benefit: If successful, the approach could produce less visible scarring and improved cosmetic outcomes after cleft lip repair.

How similar studies have performed: Small surgical series and facial wound studies have suggested botulinum toxin A can reduce scar tension and improve cosmetic outcomes, but its use specifically for cleft lip repair remains relatively novel.
