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

backgroundThe double-opposing Z-plasty is a fundamental approach for cleft palate repair. Recently, some surgeons have begun implementing a single Z-Plasty, igniting discussions on the most effective technique for enhancing postoperative outcomes. Consequently, this study sought to evaluate the outcomes of employing single and double Z-plasties within the modified Sommerlad-Furlow technique.

methods116 cleft palate patients undergoing primary surgical repair were divided into two groups: those treated with the Sommerlad-Furlow method using a double-opposing Z-plasty (S.F.2.Z.P. group, n = 58) and those receiving a single nasal Z-plasty (S.F.1.Z.P. group, n = 58). Data on cleft type and width, soft palate length, palatal fistula, and velopharyngeal function were collected. Mann-Whitney test compared the mean values between groups.

resultsThe S.F.2ZP group demonstrated a statistically significant increase in soft palate length compared to those in the S.F.1ZP group (p = 0.008). However, the S.F.1ZP group demonstrated adequate soft palate length (7.9 ± 2.8 mm) compared to the S.F.2ZP group (9.3 ± 2.8 mm). The velopharyngeal function was good in both groups, with no significant differences (P = 0.52). While the proper velopharyngeal closure was 81% in the S.F.1ZP group and 87.9% in the S.F.2ZP group, velopharyngeal insufficiency was 10.3% and 5.2%, respectively. The rates of persistent palatal fistula were 5.2% in the S.F.1ZP group and 3.4% in the S.F.2ZP group, with no significant differences found between both groups (P = 0.64).

conclusionsThere were no significant differences in crucial outcomes such as velopharyngeal function and the incidence of persistent palatal fistulas, indicating the effectiveness of both techniques. While the double-opposing Z-plasty demonstrated a statistically significant increase in soft palate length, the a nasal Z-plasty demonstrated adequate soft palate length which sufficiently enables effective velopharyngeal closure. These outcomes suggest that a single Z-plasty is both effective and easy to perform, making it a valuable surgical approach for achieving the desired outcomes.. CLINICAL RELEVANCE: The current study suggests that although the soft palate may not be as elongated with nasal Z-plasty alone compared to the double Z-plasty, it sufficiently enables effective velopharyngeal closure.
