title: Recovery of sensation in immediate breast reconstruction with latissimus dorsi myocutaneous flaps after breast-conservative surgery and skin-sparing mastectomy.
abstract: In breast reconstruction, sensation in the reconstructed breasts affects the patients' quality of life along with its aesthetic outcome. Fortunately, less invasive procedures such as breast-conservative surgery (BCS) and skin-sparing mastectomy (SSM) have greatly contributed to the improved aesthetic outcome in immediate breast reconstruction. However, there are few reports on the recovery of breast sensation after BCS and SSM. We retrospectively reviewed 104 consecutive patients who underwent immediate breast reconstruction with the latissimus dorsi myocutaneous flap between 2001 and 2006 at our institution. The sensations of pain, temperature, touch, and vibration were examined at the nipple and skin envelope during the follow-up period (range: 12-61 months, mean: 31 months), and a stratified analysis was performed to determine the critical factors affecting the sensation recovery after BCS and SSM. We found that large breast size significantly impaired the recovery of sensation in the nipple and skin envelope after BCS as well as SSM. Older age and high body mass index value were the factors which negatively affected the sensation in the skin envelope after SSM. While all our BCS patients underwent postoperative radiation therapy, it did not negatively affect the recovery of sensation in SSM patients. On the basis of these findings, we could further improve the sensation of the reconstructed breasts after BCS and SSM. Especially after SSM, the use of innervated flaps is recommended in the patients with large breast, increased age, or obesity when the nipple-areola complex is resected.
