1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

purposeHead and neck free flap (HNFF) surgery is essential in reconstructive surgery, addressing complex defects with tailored approaches. Despite high success rates, complications remain significant, influenced by patient comorbidities, flap types, and surgical complexity. This study aimed to analyze predictors of postoperative complications to improve patient outcomes.

methodsThis monocentric retrospective cohort study included patients undergoing microvascular free flap reconstruction for head and neck defects between April 2017 and July 2023. The primary outcome was flap-specific postoperative complications, including flap loss, recipient site wound healing disorders (WHD), partial flap necrosis, or anastomotic insufficiency.

resultsAmong 1050 patients, the free flap success rate was 94%, with 59 flap losses. Complications occurred in 44% of patients, most commonly WHD (29%). Prior head and neck radiotherapy was associated with anastomosis revision (OR 2.13; p = 0.02) and flap loss (OR 2.06; p = 0.02). Female sex increased the risk of flap loss (OR 2.24; p = 0.004). Alcohol abuse elevated the risk of WHD (OR 1.81; p = 0.003) and partial flap necrosis (OR 2.19; p = 0.001). Infection risk was influenced by age (OR 0.98; p = 0.01), bleeding disorders (OR 5.37; p = 0.003), and prior microvascular reconstruction (OR 2.08; p = 0.008). Increased surgical experience only slightly correlated with higher flap loss rates (OR 1.06; p = 0.02).

conclusionFree flap surgery is effective in head and neck reconstruction, though specific risk factors contribute to complications. Further research is needed to mitigate these risks. Surgical experience is essential for complex cases but is not a primary, clinically relevant predictor of complications in high-volume training centers.
