Postoperative sensitivity of the nipple-areola complex (NAC) is an important concern for women after reduction mammoplasty. Previous studies have demonstrated that sensory branches of the fifth anterior intercostal nerve are important for innervating the NAC and that using an inferior pedicle technique is associated with improved sensory retention. The significance of this case report is that it demonstrates the importance of the fifth anterior intercostal sensory nerve branches using a prototype fluorescent imaging camera. The benefit of this device is that it can detect intraoperative auto-fluorescence of nerves and facilitate their identification and preservation, potentially facilitating the retention of sensation in the NAC and surrounding skin. The goals of this article are, therefore, to demonstrate the importance of this neurovascular pedicle when the inferior pedicle technique is used for breast reduction; and to provide demonstrative evidence of the nerve's presence within the fifth anterior intercostal artery perforator pedicle. The case involved a woman with mammary hypertrophy who underwent bilateral reduction mammoplasty using the inferior pedicle technique. Full NAC sensation was demonstrated on postoperative day 3 with complete sensory recovery at 1- and 3-month follow-up confirmed. To our knowledge, this is the first reported instance of the fifth intercostal nerve being visualized during aesthetic breast surgery, demonstrating the importance of this neurovascular bundle for sensory preservation when an inferior pedicle reduction mammaplasty technique is used.
