As the survival rate of tongue cancer has increased, longer-term results of tongue reconstruction are also being considered. The aim of this study was to report the long-term outcomes of total glossectomy. Of 14 patients who underwent total glossectomy, 11 were reconstructed with the rectus abdominis musculocutaneous free flap and 3 with the anterolateral thigh free flap. We reviewed survival rate, swallowing capacity, speech intelligibility, and volume reduction in flaps. Swallowing capacity and speech intelligibility were evaluated by visual analog scale scores (7 points) at 1 to 7 years after surgery, and changes in neotongue volume were examined by dividing volume into 4 stages. The 5-year disease-specific survival rate was 71%. Almost all patients were able to eat a soft diet and resume verbal communication. However, a sufficient volume of the reconstructed tongue was decreased over the course of time. Volume change was more definitive in the cases using the anterolateral thigh free flap than the rectus abdominis musculocutaneous free flap. Neotongue volume was also correlated with swallowing capacity and speech intelligibility. In total tongue reconstruction, wide and thick flaps such as the rectus abdominis musculocutaneous flap had better outcomes. Overcorrection with a sufficient flap volume is recommended for adequate oral intake owing to volume loss caused by radiation therapy, and functional muscle transfer should also be considered to prevent muscle atrophy. Lastly, static suspension procedures are emphasized to prevent airway aspiration for larynx preservation.

Summary: Deep inferior epigastric artery perforator (DIEP) flap surgery is one of the most common techniques for breast reconstruction using abdominal tissue. Although the DIEP flap reduces donor-site morbidity when compared with the conventional free transverse rectus abdominis musculocutaneous flap, violation of the anterior rectus sheath, rectus muscle, and motor nerves cannot be avoided. To further minimize tissue damage in the donor site, the use of a surgical robotic system for DIEP flap harvest with a totally extraperitoneal approach has been suggested. This totally extraperitoneal approach has a long learning curve because of the narrow preperitoneal space and the difficulty of converting a potential space to an actual space. Thus, the authors suggest a single-port robotic system optimized for narrow surgical spaces as a feasible option for DIEP flap harvest by a totally extraperitoneal approach, which has a shorter learning curve.

Seeking smaller and indistinct incisions, physicians have attempted endoscopic breast surgery in breast cancer patients. Unfortunately, there are some limitations in the range of movement and visualization of the operation field. Potentially addressing these limitations, we investigated the outcomes of gas and gasless robot-assisted nipple-sparing mastectomy (RANSM) with immediate breast reconstruction (IBR). Ten patients underwent 12 RANSM with IBR between November 2016 and April 2018. Patients with tumors measuring >5 cm in diameter, tumor invasion of the skin or nipple-areolar complex, proven metastatic lymph nodes, or planned radiotherapy were excluded. Age, breast weight, diagnosis, tumor size, hormone receptor status, and operation time were retrospectively collected. Postoperative outcomes including postoperative complications and final margin status of resected were analyzed. The median total operation time and console time were 351 min (267–480 min) and 51 min (18–143 min), respectively. The learning curve presented as a cumulative sum graph showed that the console time decreased and then stabilized at the eighth case. There was no open conversion or major postoperative complication. One patient had self-resolved partial nipple ischemia, and two patients experienced partial skin ischemia. We deemed that RANSM with IBR is safe and feasible for early breast cancer, benign disease of the breast, andBRCA 1/2mutation carriers. RANSM is an advanced surgical method with a short learning curve.
