Endoscopic transnasal drainage of frontal epidural abscesses.
Bibliographic record
Abstract
BACKGROUND: Although rare, sinogenic intracranial epidural frontal abscesses remain a serious and potentially life-threatening complication of sinusitis. Traditional therapy involves a combination of intravenous antibiotics, sinus surgery, and neurosurgical drainage through an external approach. OBJECTIVE: In this report, we present a technique in which a purely endoscopic transnasal approach was used to treat both the sinusitis and the intracranial abscess. Four cases are discussed illustrating the technique and its outcomes. METHODS: In all cases, endoscopic sinus surgery was performed to treat underlying sinus disease. Next, under image guidance, an endoscopic, intranasal opening through the skull base was performed for intracranial access and abscess drainage. RESULTS: Our patients tolerated this procedure well and fully recovered with resolution of all presenting neurologic features. CONCLUSION: This approach may offer a safe and effective alternative to frontal craniotomy for selected cases and can result in lower postoperative morbidity than traditional approaches.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
