Schneiderian membrane perforation repair using a crosslinked collagen membrane: a retrospective cohort study.

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.
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
objectivesPerforation of the Schneiderian membrane (SM) is a common intraoperative complication of sinus augmentation. This study aimed to evaluate risk factors for SM perforation, and to compare clinical outcomes between patients with SM perforation repaired using crosslinked collagen membranes (CLM) compared to those with an intact SM.
methodsA retrospective cohort study was conducted at a single tertiary medical center. Data was collected on patients requiring sinus augmentation via lateral approach prior to implant placement. The collected data included demographics, surgical details, implant outcomes, radiographic analysis, and presence of SM perforation. In cases of perforation a CLM was used to repair the SM. Statistical analysis was performed to evaluate risk factors for perforation and whether SM perforation repair using CLM influenced early implant failure (EIF). A p-value < 0.05 was considered significant.
resultsData on 194 individuals who underwent 278 lateral approach sinus augmentation procedures was collected. SM perforation occurred in 66 (23.74%) sinuses. Treatment of SM perforation using CLM yielded similar results to sinuses without perforations: EIF and the augmented gained bone did not correlate with SM perforation. Younger patients, and thick SMs (> 3 mm) had significantly lower risk of perforation.
conclusionsOlder age and thinner SMs are risk factors for sinus membrane perforations. No significant differences in bone gain and EIF were found between perforated and intact membranes. CLINICAL RELEVANCE: Schneiderian membrane perforation repair using crosslinked collagen membrane provides comparable results to sinus augmentations without perforations, demonstrating its effectiveness in preventing complications.
