Abstract
Introduction: Orbital cavernous malformations (OCMs) are benign vascular lesions frequently associated with progressive proptosis and visual disturbances due to their slow growth and compression of adjacent structures. Multiple surgical approaches have been developed for their treatment, including microsurgical transfacial-transorbital approaches (MTTAs), cranio-orbital approaches (MCOAs), orbitotomies (MOs), endoscopic endonasal approaches (EEAs), and endoscopic transorbital approaches (ETOAs). However, the optimal approach remains a topic of debate. Research objective: This systematic review aims to compare the resection rates, postoperative complications, and clinical outcomes across various surgical approaches for OCM management. Methods: A comprehensive literature search was performed in PubMed, Embase, and the Cochrane Library according to PRISMA guidelines. Studies reporting surgical treatment of OCMs with clinical outcome data were included. Study quality was assessed using the Newcastle-Ottawa Scale. Statistical analyses were conducted using chi-square and Mann-Whitney U tests. Results and conclusions: Of 239 screened studies, 94 met inclusion criteria, comprising 1007 patients (mean age 43.9 years; 58.5 % female). Proptosis (63.2 %) and visual impairment (48.1 %) were the most common symptoms. Most lesions were intraconal (80 %) and laterally positioned (42.8 %). EEAs were the most commonly used approach (40.1 %), followed by MOs (25.7 %) and MTTAs (21.6 %). Gross total resection was achieved in 93.7 % of cases. Complications were infrequent: visual acuity worsening (3.9 %), diplopia (2.4 %), and enophthalmos (1.7 %). Functional outcomes improved significantly, particularly visual acuity (65.1 %) and proptosis (61.6 %). EEAs provide high resection rates with minimal morbidity, especially for medial OCMs. ETOAs represent a promising, minimally invasive option for laterally located lesions.

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
