| Surgical site microbial load. Timepoint: Before the surgical hair removal procedure, the first microbiological sample (T1) will be collected by the researcher from the dry skin of the surgical site without any prior skin cleansing or antiseptic preparation. Immediately after hair removal, the second microbiological sample (T2) will be obtained from the surgical site by the researcher. After the patient is transferred to the operating room and following induction of anesthesia, patient positioning, and appropriate skin preparation and draping, the third microbiological sample (T3) will be collected. At the end of the surgical procedure, after complete and proper wound closure, the fourth microbiological sample (T4) will be obtained by the researcher immediately before application of the surgical dressing. Method of measurement: After collection, the samples will be stored in the operating room refrigerator and collected at 15:00 at the end of the day. The samples will then be placed in a secure transport medium (a plastic sample transport box containing ice) and transferred to the Microbiology Laboratory of Iran University of Medical Sciences. In the laboratory, the samples will be cultured on blood agar by a microbiologist and incubated at 37 °C for 24 hours. Subsequently, the grown colonies will be counted by the researcher and recorded on the microbial load data collection form.;Surgical Site Infection. Timepoint: Assessments will be performed 24 hours after surgery and 30 days postoperatively. Method of measurement: At 24 hours postoperatively, the surgical site will be inspected for signs of surgical site infection by the attending surgeon and the researcher, and findings will be recorded using the WHO surgical site infection assessment form. Prior to discharge, patients will be educated by the researcher on the signs of surgical site infection and provided with the WHO assessment form. Patients will be instructed to monitor the surgical site for 30 days after s | — |
