Abstract
PURPOSE: To determine the tumor control rate of basal cell carcinoma (BCC) of the eyelid margin managed by full-thickness eyelid resection with en-face frozen section-controlled margins and primary reconstruction of the defect. METHODS: This is a retrospective, consecutive, noncomparative, longitudinal interventional case series from a single institution. A review of medical records of all patients with BCC involving the eyelid margin treated by full-thickness en-face frozen section histopathology between June 1997 and June 2011 was conducted. All cases were managed with gross full-thickness resection of the eyelid margin tumor with subsequent reconstruction. Intraoperative frozen section histopathology was performed on additional 1-mm thick medial, lateral, and inferior/superior specimens in a full-thickness en-face fashion. The main outcome measure was rate of recurrence over the follow-up period. Additional data collected included patient demographics, lesion site and size, histopathology, reconstructive technique, and postoperative complications. RESULTS: The review resulted in a total of 74 patients with 77 lesions. Of these, 45 lesions had a minimum 5-year follow up. Those cases that involved the lacrimal system were excluded resulting in a total of 43 cases for analysis, which had a mean follow up of 6.4 years (range, 5.0-13.0). Three cases (6.9%) represented a recurrent BCC, while all other cases were primary BCCs. The histopathological subtypes included nodular (65.1%), infiltrative (18.6%), and superficial (16.3%). There were no cases of recurrence (100% cure rate) over the follow-up period. Most defects (88.4%) were reconstructed by direct closure or a temporal rotation flap. The only complication noted was the development of a hypertrophic scar in 1 patient that resolved with conservative management. In the total series of 77 lesions, the mean follow-up period was 4.5 years (range, 0.5-13.0). One recurrence (1.3%) was detected after 1.1 years for an infiltrative BCC measuring 10.0 mm in diameter that involved the lacrimal system. CONCLUSIONS: Eyelid margin BCC can be managed effectively with full-thickness en-face frozen section-controlled excision and primary reconstruction of the defect. The high cure rate compares favorably with other excision techniques such as Mohs micrographic surgery, with the advantages of a single operation and excellent reconstructive result.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
