**Core Concept**
Tubal ligation reversal, also known as tubal recanalization, is a surgical procedure aimed at restoring fertility in women who have undergone tubal ligation. The success of this procedure depends on various factors, including the type of ligation used, the duration since the original surgery, and the presence of any post-ligation complications.

**Why the Correct Answer is Right**
The procedure with the maximum chance of re-canalization during surgery for reversal of tubal ligation is **microsurgical tubal anastomosis**. This technique involves the use of an operating microscope to meticulously reconnect the cut ends of the fallopian tubes using fine sutures. The precise technique and magnification provided by the microscope enable the surgeon to accurately reattach the tubes, thereby maximizing the chances of successful re-canalization. This procedure is particularly effective when performed by experienced surgeons and is associated with higher success rates compared to other methods.

**Why Each Wrong Option is Incorrect**
* **Option A:** Tubal ligation reversal by **laparoscopic microsurgery** is a valid technique, but it is not associated with the maximum chance of re-canalization compared to microsurgical tubal anastomosis.
* **Option B:** **Tubal implantation**, also known as corneostomy, involves the implantation of a segment of the fallopian tube into the uterine cavity. This procedure is not as effective as microsurgical tubal anastomosis in restoring tubal patency.
* **Option D:** **Salpingostomy**, which involves making an incision in the fallopian tube to allow it to heal and potentially re-canalize, is not as effective as microsurgical tubal anastomosis in restoring tubal patency.

**Clinical Pearl / High-Yield Fact**
The key to successful tubal ligation reversal is the experience and skill of the surgeon, as well as the timing of the procedure. Women who undergo tubal ligation reversal within 10-15 years of the original surgery tend to have better outcomes.

**Correct Answer: C. Microsurgical tubal anastomosis.**
