N2 - Background: The aim of this study was to investigate the somatosensory changes at the forearm donor region after using different types of modified flap surgical techniques. Methods: Thirty-one patients, who underwent oral and maxillofacial reconstructive surgery involving the use of a traditional radial forearm flap (TRFF) or two modified radial forearm flap techniques (MRFF-I; MRFF-II), participated in the study. Cold detection threshold (CDT), warm detection threshold (WDT), cold pain threshold (CPT), heat pain threshold (HPT), pressure pain threshold (PPT), mechanical detection threshold (MDT), and mechanical pain threshold (MPT) were assessed at four sites of the forearms corresponding to the middle of the vascular pedicle (VP) area, the middle of the forearm flap area, and the corresponding contralateral sites (cVP and cFF) at about 5.0 ± 1.9 months after the surgery. Data were analysed with one-way ANOVA, and post-hoc tests were performed using Tukey's Honest Significant Difference test. Results: Significant differences between the VP and cVP sites were detected for WDT (P < 0.001) in TRFF and for WDT (P < 0.001) and MDT (P = 0.006) in MRFF-I. Significant differences among TRFF, MRFF-I, and MRFF-II at the VP site were detected for CDT (P = 0.022), WDT (P < 0.001), and MDT (P = 0.015). MRFF-II was associated with significantly higher sensitivity compared to that of TRFF for WDT (P = 0.017) and higher sensitivity compared to that of MRFF-I for CDT (P = 0.017), WDT (P < 0.001), and MDT (P = 0.013). Conclusions: Significant sensory loss was detected for all types of surgical procedures with free forearm flaps. However, the MRFF-II was associated with a better sensory recovery at short follow-up after surgery. These results suggest that a longer follow-up period and larger sample size should be included in future studies.
