## **Core Concept**
Cleft lip repair is a surgical procedure aimed at correcting a congenital deformity of the lip. The timing of the surgery is crucial for optimal outcomes. The general principle is to perform the repair when the infant is old enough to safely undergo anesthesia but still young enough to benefit from early intervention.

## **Why the Correct Answer is Right**
The correct answer, **when the infant is around 3 months old**, reflects the current consensus in pediatric plastic surgery. Performing the repair at this age allows for several benefits: the infant is still young enough for the tissues to be highly plastic and conducive to healing, yet old enough to minimize the risks associated with anesthesia. Early repair also helps in reducing the psychological impact on the family and can improve feeding and speech development.

## **Why Each Wrong Option is Incorrect**
- **Option A:** Performing cleft lip repair **too early (e.g., immediately after birth)**, is generally not recommended due to the risks associated with anesthesia in very young infants and the potential for complications.
- **Option B:** Waiting **until the child is several years old** can delay the benefits of early intervention, potentially affecting speech development and increasing the psychological impact on the child.
- **Option D:** Suggesting **a wide range or unspecified age** does not provide a clear guideline for optimal surgical timing.

## **Clinical Pearl / High-Yield Fact**
A key point to remember is that the timing of cleft lip repair often follows the "Rule of 10s": the child should be at least 10 weeks old, weigh 10 pounds, and have a hemoglobin level of 10 g/dL. This guideline helps in minimizing the risks associated with surgery.

## **Correct Answer:** . 3 months.
