¿Afecta el número de bucles a los resultados de las faringoplastias barbadas? Un estudio comparativo entre dos técnicas

Introduction

The use of barbed sutures for pharyngoplasty techniques is a new trend in sleep apnea surgery, but little is known about its short-term results depending on the different techniques. The purpose of this study was to analyze the surgical results in two different centers using barbed sutures with different barbed pharyngoplasty techniques.

Material and methods

This is a multicenter retrospective study of patients with obstructive sleep apnea (OSA) undergoing surgery, all of whom underwent pharyngoplasty with barbed suture using a classic or modified technique, which may or may not be associated with other surgical techniques. A univariate and multivariate statistical analysis were performed to assess the relationship of these surgical techniques with surgical success and with different descriptive variables.

Results

The final sample size was 126 patients. A surgical success rate of 39.7% was obtained for a postoperative AHI < 10/h and a 51.6% success rate according to Sher's criteria. A greater proportion of success was observed in the modified barbed pharyngoplasty technique that was not maintained after the multivariate analysis, as with other factors such as age, ODI or the presence of nasal surgery.

Conclusion

Non-resective pharyngoplasty with barbed sutures is an effective technique for the treatment of OSA in selected patients, with both the classic technique and the modified alternatives having good postoperative results, with no differences observed in relation to surgical success between both. More studies are necessary to evaluate the differences between both techniques in more homogeneous groups.
