The ability to achieve a good functional outcome, quality of life, and patient satisfaction related to the donor site of free flaps is an important factor in flap selection. One of the main advantages of an anterolateral thigh (ALT) free flap is its minimal donor-site morbidity. We conducted a study to analyze healing of ALT flap donor sites based on the type of closure. A total of 65 patients were included in the study. We divided the participants into two cohorts (i.e., primary closure [n = 51] and skin grafting [n = 14]). There were no statistically significant differences between the two cohorts relative to age, gender, or risk factors for wound healing (e.g., tobacco use, obesity, diabetes mellitus, and cardiovascular disease). We found there was a statistically significant difference (p < .05) between the mean donor-site wound healing time in the primary closure group (n = 51; 22.41 days [±9.94]) compared with the skin grafting group (n = 14; 54.57 days [±21.59]). To reduce wound healing time, improve cosmetic results, and increase functional outcomes in patients undergoing ALT free flap, we recommend using primary closure for the donor sites and avoiding skin grafting whenever possible.
