“…The "C" shape incision was designed along the keloid trailing edge. Different to "X" shape incision, the purpose of “C” shape incision was that surgical scars might be located behind the ear [ 17 ]. Besides, the "C" shape incision was less than half of the keloid circumference to ensure the blood supplyment of scar flap.…”

Background Although multiple methods have been proposed to treat auricular keloids, low curative effects and high recurrence rates are currently major clinical problems. Thereinto, surgery combined with radiotherapy and triamcinolone acetonide injection is considered to be the proper choice for comprehensive treatment of auricular keloids. This study aimed at evaluating the therapeutic effect of individualized surgery combined with radiotherapy for the treatment of auricular keloids. Methods From February 2014 to February 2017, 67 patients with 113 auricular keloids in total were enrolled in this study. According to specific conditions of lesions, the local tissue and patients’ individual wishes, different surgical methods were selected to analyze the scar excision and repairment of the defect. Within 24 h after the keloid was excised, 5 MeV electron beam irradiation by the linear accelerator was used by radiotherapy with a total dose of 20 Gy at interval of 1 day for 10 consecutive times. Triamcinolone acetonide was injected immediately after surgery, and per month afterward in the following three months. Results 113 keloids in total were received treatment. The follow-up period was 24 months. Fourteen keloids (12.39%) showed subjective recurrence with a success rate of 87.61%. Wilcoxon matched-pairs rank-sum test was used to compare the differences of the 24-month postoperative VSS scores and the preoperative VSS scores. The VSS scores were as follows: 82 keloids (72.57%) scored less than 5 points (good result), 21 keloids (18.58%) scored 6 to 10 points (fair result), and only 10 keloids (8.85%) scored more than 10 points (bad result). The effective rate was 91.15%. Conclusions Individualized surgery combined with early postoperative radiotherapy and triamcinolone acetonide injection is an ideal treatment method to ensure good auricular appearance, low incidences of complications and recurrence based on effective treatment of auricular keloids.

“… 22 We have previously used end-to-side sensory nerve repairs in other clinical scenarios and found that they are sufficient to promote nerve regrowth through nerve grafts. 29 – 31 This refinement to the first stage of facial reanimation may further improve functional outcomes. We are currently using this technique as part of a multimodal approach to improve axon regeneration through the CFNG and continue to document the functional outcomes in these patients.…”

Smiling is an important aspect of emotional expression and social interaction, leaving facial palsy patients with impaired social functioning and decreased overall quality of life. Although there are several techniques available for facial reanimation, staged facial reanimation using donor nerve branches from the contralateral, functioning facial nerve connected to a cross-face nerve graft (CFNG) is the only technique that can reliably reproduce an emotionally spontaneous smile. Although CFNGs provide spontaneity, they typically produce less smile excursion than when the subsequent free functioning muscle flap is innervated with the motor nerve to the masseter muscle. This may be explained in part by the larger number of donor motor axons when using the masseter nerve, as studies have shown that only 20% to 50% of facial nerve donor axons successfully cross the nerve graft to innervate their targets. As demonstrated in our animal studies, increasing the number of donor axons that grow into and traverse the CFNG to innervate the free muscle transfer increases muscle movement, and this phenomenon may provide patients with the benefit of improved smile excursion. We have previously shown in animal studies that sensory nerves, when coapted to a nerve graft, improve axonal growth through the nerve graft and improve muscle excursion. Here, we describe the feasibility of and our experience in translating these results clinically by coapting the distal portion of the CFNG to branches of the infraorbital nerve.

“…In practice, the distal end of the damaged nerve was grafted and connected to the contralateral donor nerve crossing the face [ 50 ]. Catapano et al applied this technique to reinnervate the mental nerve using the sural nerve as the donor nerve [ 51 ]. The results are preliminary with a small sample size and short follow-up.…”

The reconstruction and rehabilitation of jaws following ablative surgery have been transformed in recent years by the development of computer-assisted surgery and virtual surgical planning. In this narrative literature review, we aim to discuss the current state-of-the-art jaw reconstruction, and to preview the potential future developments. The application of patient-specific implants and the “jaw-in-a-day technique” have made the fast restoration of jaws’ function and aesthetics possible. The improved efficiency of primary reconstructive surgery allows for the rehabilitation of neurosensory function following ablative surgery. Currently, a great deal of research has been conducted on augmented/mixed reality, artificial intelligence, virtual surgical planning for soft tissue reconstruction, and the rehabilitation of the stomatognathic system. This will lead to an even more exciting future for the functional reconstruction and rehabilitation of the jaw following ablative surgery.
