Sleep {middle dot} 9: An approach to treatment of obstructive sleep apnoea/hypopnoea syndrome including upper airway surgery
Bibliographic record
Abstract
Purpose Prospective study evaluating outcomes of individually sutured platinum segment chains in upper eyelid loading. Methods Single-centre, single-surgeon, prospective study. Upper eyelid loading with 0.4 and 0.2 g platinum segment chains for lagophthalmos. Segments were sutured to create a desired weight and attached to superior tarsus and distal levator aponeurosis following levator recession. Primary outcome measures: improvement in lagophthalmos and complications. Secondary outcome measures: cosmesis of eyelid margin contour and implant prominence. Minimum 3-month follow-up. Results Eighteen eyelids of 17 patients received segment chains (mean weight 1.2 g, range 0.8–1.6 g) and 3 for exchange of pre-existing gold weights. Median follow-up was 10 (range 6–17) months. Mean blink lagophthalmos improved from 7 (3–10) mm to 3 (0–6) mm (p<0.0001), and gentle closure from 3.2 (0–8) mm to 1.1 (0–4.9) mm (p=0.0004). Twelve patients (71%) reported no prominence, and the remainder, mild prominence only. The chain was graded as having no prominence in 78% (14/18) eyelids. Two required segment adjustments with removal of a single 0.2 g segment at 11 months and transfer of 0.4 g segment to the contralateral eyelid at 16 months, respectively. One complication (posterior, trans-conjunctival exposure above the superior border of the tarsal plate) was seen 12 months post surgery, requiring repositioning. Conclusions Platinum segment chains provide benefits of platinum chains with additional advantages of postoperative adjustibility. They can be used as an addition to pre-existing in situ weights or chains. Trial registration number REC reference: 13/SW/0146. IRAS project ID: 119022.

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.
