Comparison of the Interrupted and Continuous Suture Techniques for the Closure of Oral and Nasal Mucosal Layers in Cleft Palate Surgery

Abstract

BackgroundCleft lip and palate are common congenital craniofacial anomalies, treated conventionally by surgery at the ages of six to 18 months. Mostly, the interrupted suture technique is used to close the nasal and oral layers of the palate. In some studies, the interrupted suture technique was compared with continuous suture techniques for the closure of oral and nasal layers and found that there was less utilization of time and suture materials in the continuous technique. This study was designed to see the outcomes of interrupted versus continuous suture techniques. Materials & methodsA total of 36 patients were included in the study and were divided into two groups according to the type of suturing technique. The time utilized for the repair of the oral and nasal layers of the cleft palate, the number of suture packs utilized, and the incidence of fistula formation were noted and compared between the two groups. Out of 36 patients, 17 were included in group A (operated by interrupted techniques), and 19 were included in group B (operated by the continuous technique). ResultsThe mean time taken to close nasal layer in Group A was 18.12 ± 1.16 minutes and in Group B was 8.37 ± 0.89 minutes (p-value < 0.001), whereas for oral layer closure, it was 14.00 ± 1.17 minutes in group A and 6.00 ± 0.57 minutes in group B (p-value < 0.001). The average usage was 2.26 ± 0.45 suture packs for repair with the continuous technique and 4.00 ± 0.35 suture packs when repaired via interrupted stitches. There was no difference noted in postoperative outcomes in both groups in terms of postoperative fistula and wound dehiscence. ConclusionA continuous suture technique for closing the oral and nasal layers in patients with cleft palate is recommended, as it is more beneficial in terms of time, cost-effectiveness, and utilization of suture material.
