Higher incidences of neuropathic pain and altered sensation following radial forearm free flap: A systematic review
Journal of Plastic, Reconstructive & Aesthetic Surgery(2022)
Abstract
Background: The radial forearm free flap (RFFF) has been used extensively for com-plex tissue defect reconstructions; however, the potential for significant donor-site morbidity remains a major drawback. Despite an abundance of literature on donor-site morbidities, no consensus has been reached on exact incidences of sensory morbidities that vary largely be-tween 0% and 46%. Incidences of neuropathic pain in the donor site following RFFF still lack, even though clinical experience shows it often occurs. Therefore, the purpose of this system-atic review was to identify the incidence of neuropathic pain and altered sensation in the hand following harvesting of a RFFF. Methods: A systematic search was performed in multiple databases (Embase, Medline, Cochrane, Web of Science, and Google Scholar). Studies from 1990 onwards that reported donor-site morbidities following harvest of the RFFF were included. Analyzed parameters in-cluded hand pain, hypoesthesia, cold intolerance, hyperesthesia, neuroma formation, pares-thesia, sharp sensation loss, light sensation loss, and defect closure. Results: Of the 987 selected studies, 51 eligible articles were selected. The mean level of evidence was 3 (SD 0.6). Twenty articles reported pain as a donor-site morbidity, and the mean incidence of pain reported was 23% (SD 7.8). Hypoesthesia was reported by 37 articles and had a mean incidence of 34% (SD 25). Locations of pain and hypoesthesia included, amongst others, the area of the radial sensory nerve and the skin graft area. The mean incidences of cold intolerance and hyperesthesia were 13% (SD 13) and 16% (SD 15), respectively. Conclusion: The results of this systematic review suggest that 23% of all patients are deal -ing with neuropathic pain in the donor-site following harvest of an RFFF. Future studies should therefore focus on the prognostic factors and preventive measures of neuropathic pain to further improve clinical outcomes of this widely used flap.
