Abstract
BACKGROUND: There is ongoing debate over which surgical technique is the safest for brow elevation. OBJECTIVES: The authors outline complication rates for a variety of open and endoscopic browlift techniques based on the results of a literature review. METHODS: The following databases were searched to capture relevant studies: MEDLINE, EMBASE, CINAHL, LILACS, Web of Science, Cochrane Libraries, controlled-trials.com, and clinicaltrials.gov. Eighty-two studies met the inclusion criteria. Assuming between-study heterogeneity due to the limitations and biases inherent to case series, a random-effects model was used to calculate weighted proportions. Pooled weighted proportions with 95% confidence intervals were determined. RESULTS: All open and endoscopic procedures are associated with a variety of complications. Unacceptable scarring and paresthesia are the most common complications among all surgical browlifts. For anterior hairline incision with subcutaneous dissection, alopecia occurred in 8.5% of patients, paresthesia in 5.4%, unacceptable scarring in 2.1%, and skin necrosis in 1.8%. For coronal incision with subgaleal dissection, unacceptable scarring occurred in 3.6% of patients, hematoma in 0.5%, and infection in 0.2%. Endoscopic techniques with subperiosteal dissection had the highest complication rates: 6.2% for paresthesia, 3.6% for asymmetry, 3.0% for alopecia, and 2.7% for lagophthalmos. CONCLUSIONS: Although complication rates vary with respect to incision site and plane of dissection, endoscopic techniques are associated with a larger variety of complications than open approaches. The findings should be interpreted with caution due to the limitations inherent to a case series. A well-designed comparative study is needed to evaluate the "true" rate of complications among the various browlift techniques.

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
