The Single Z-Plasty for Cleft Palate Repair: A Preliminary Report

Single vs. Double-Opposing Z-Plasty: Evaluating Their Impact on Palatoplasty Postoperative Outcomes

BACKGROUND

The 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.

METHODS

116 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.

RESULTS

The 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).

CONCLUSIONS

There 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.

Placement of an antibiotic oral pack on the hard palate after primary cleft palatoplasty: a randomized controlled trial into the effect on fistula rates

OBJECTIVE

The objective of this study is to determine whether placement of an antibiotic oral pack on the hard palate reduces fistula rates after primary cleft palatoplasty.

SUBJECTS AND METHODS

This study was a parallel blocked randomized controlled trial. The study consisted of two groups of 100 patients each with non-syndromic unilateral complete cleft lip, alveolus, and hard and soft palate that underwent primary palatoplasty. Group A had an oral pack placed on the hard palate for 5 days postoperatively while group B did not. Occurrence of fistulae between both groups was tested using odds ratios (OR).

RESULTS

In 2% of the patients in group A, a fistula was found 6 months after palatal surgery. In contrast, in 21% of the patients in group B, a palatal fistula could be confirmed. The fistula occurrence in group A was statistically significantly lower than that in group B (OR = 0.0768, CI = [0.02 … 0.34], p < 0.001).

CONCLUSION

The findings of this study provide evidence that the rate of fistula formation after primary palatoplasty is significantly reduced if a pack soaked with antibiotic cream is placed on the palate postoperatively for 5 days.

CLINICAL RELEVANCE

The use of an antibiotic pack after cleft palate repair can be recommended to prevent occurrence of oronasal fistulae.

Fistula incidence after primary cleft palate repair: a systematic review of the literature

BACKGROUND

The development of an oronasal fistula after primary cleft palate repair has a wide variation reported in the literature. The aim of this review is to identify the reported oronasal fistula incidence to provide a benchmark for surgical practice.

METHODS

A systematic review was undertaken to investigate the incidence of fistula. Multiple meta-analyses were performed to pool proportions of reported fistulae, in each data set corresponding to the continent of origin of the study, type of cleft, and techniques of cleft palate repair used.

RESULTS

A total of 9294 patients were included from 44 studies. The overall incidence of reported fistula was 8.6 percent (95 percent CI, 6.4 to 11.1 percent). There was no significant difference in the fistula incidence corresponding to the continent of origin of each study or the repair technique used. The incidence of fistula in cleft lip-cleft palate was 17.9 percent, which was significantly higher (p = 0.03) than in cases of cleft palate alone (5.4 percent).

CONCLUSIONS

Palatal fistulae were more likely to occur in cases of combined cleft lip-cleft palate, compared with cleft palate alone. The authors would recommend the prospective examination and recording of all fistulae to a standardized classification scheme.
