Effect of full tumescent anesthesia in the dermis on wound recovery in the donor area during FUE hair transplantation
Objective To explore the effect of"tumescent and take"after full tumescent anesthesia in the dermis on wound re-covery in the donor area during FUE hair transplantation.Methods A retrospective study was conducted on 96 patients with androgenic alopecia or hairline adjustment who underwent FUE hair transplantation.Hair follicles were harvested from the occipital region as the dom-inant donor site for transplantation to recipient sites.The patients were divided into two groups according to the method of tumescent anes-thesia in the donor area.The observation group consisted of 48 patients who received a limited range of"tumescent and take"intradermal injection of tumescent fluid in the donor site,while the control group included 48 patients who received conventional tumescent anesthesia in the donor site.Regular follow-up was conducted for 30 to 60 d to observe.The wound healing conditions of the two groups,such as exu-dation type,exudation volume,skin color around the wound,tissue type and healing time,were compared.Results Three days after the surgery,the observation group had lower scores than the control group for exudation volume,skin color around the wound,and tissue type.The differences were statistically significant(P<0.05).While there was no significant difference in terms of exudation type(P>0.05).Four and five days after the operation,the differences of the score of exudate volume,exudation type and tissue type were statistically significant(P<0.05).Four days after the operation,the score of skin color around the wound was significantly lower in the observation group than in the control group(P<0.05).Five days after the operation,the donor wounds of all patients were normal or pink.The healing time of observa-tion group[(4.08±0.28)d]was significantly shorter than that of control group[(4.44±0.77)d](t=-2.998,P<0.05).Four days after the surgery,the percentage of spotty pale red scar area in the donor area of the observation group[(8.69±1.28)%]was significantly lower than that of the control group[(9.69±2.19)%],and the difference was statistically significant(t=-2.73,P<0.05).Conclusion In FUE hair transplan-tation,the wound healing condition of the donor area and speed of the patients with sufficient intradermal swelling and"tumescent and take"technique are significantly better than those of the conventional tumescent technique group.
