PATIENT AND OBSERVER SCAR ASSESSMENT FOLLOWING BASAL CELL CARCINOMA SURGERY: MULTICENTER QUASI EXPERIMENTAL STUDY

Objective: To assess patient and observer reported scar quality after Basal cell carcinoma surgery of face using the Patient and Observer Scar Assessment Scale (POSAS). Study Design: Quasi experimental study. Place and Duration of Study: Dermatology Department, Tertiary Care Hospitals at Multan and Karachi and Plastic Surgery Department, Tertiary Care Hospital Multan, from Apr to Sep 2020. Methodology: Patients with basal cell carcinoma that full filled inclusion and exclusion criteria were enrolled by consecutive sampling technique at Dermatology and Plastic Surgery Department after informed consent. Surgical excision was followed by reconstruction of defect either by direct closure or by rotation or advancement flap. Surgical scar was assessed independently at 8 weeks by POSAS. Data was analyzed with SPSS-23. Results: A total of 27 patients were enrolled in study. There were 11 (37.9%) males and 16 (59.25%) females between ages of 45-70 years. Basal cell carcinoma was located on cheek in 15 (55.5%), nose in 9 (33.3%), temple 2 (7.4%) and forehead 1 (3.7%) cases. Direct closure was performed in 6 (22.2%), rotation flaps in 10 (40.7%), and advancement flaps in 11 (40.7%) cases. Mean score of observer opinion about surgical scar between different surgical techniques was not statistically significant (p=0.191). How-ever, mean score of patient opinion of scar between different surgical techniques was statistically significant (p=0.032). Conclusion: POSAS is a valid tool for scar evaluation by patient and observer-reported scar qualities after Basal cell carcinoma surgery.
