Design outcomes

Primary

Measure	Time frame
Resected basal cell carcinomas will be classified according to facial aesthetic subunits and clinical data including tumor size, tumor borders and degree of pigmentation, surgical findings, surgical margin and reconstructive method, and the presence or absence of recurrence will be obtained from electronic medical records. The risk of recurrence (low risk or high risk) will be evaluated according to the NCCN Guidelines (version 2, 2025). Histopathological findings of the resected BCCs including BCC subtype and the status of horizontal and vertical surgical margins will be obtained from pathological reports preserved in our department. Histological slides stored in the pathology department of our hospital will be used. Reconstructive procedures will be compared between patients who underwent immediate, single stage reconstruction following tumor excision and those who underwent delayed, two stage reconstruction and differences in recurrence rates between the two groups will be evaluated. Tumor size and depth of invasion will be measured and evaluated based on histopathological examination.	—

Secondary

Measure	Time frame
The relationship between BCC subtype, horizontal and vertical margin status, and the recurrence rate at one year postoperatively will be analyzed. Tumor characteristics associated with positive surgical margins will be evaluated, and risk factors for margin positivity will be analyzed statistically.	—
