The new “cubism” graft technique in tympanoplasty: A randomized controlled trial

Abstract

Objectives The aim of this prospective, randomized‐controlled study is to analyze the outcomes of a new graft technique in tympanoplasty and compare its outcomes with cartilage island graft plus extra perichondrium. Methods A total of 44 patients with noncomplicated chronic otitis media were included in this prospective randomized‐controlled clinical trial. Patients were randomly divided into 2 double‐layer graft groups: The cartilage island graft + cubism graft (study group) and the cartilage island graft + extra perichondrium (control group). The main outcome measures of the study were the air‐bone gap (ABG), ABG gain, and graft status. Results Graft success rate was 100% and 95.5% in the study group and the control group, respectively. There were statistically significant differences in the postoperative first month ABG and ABG gain between study and control groups (P < .05). ABG and ABG gain showed no significant differences in the postoperative sixth month between groups (P > .05). Conclusion This study revealed that both graft techniques have satisfactory functional and morphological results compared to preoperative findings. The use of cubism graft with cartilage island graft has significantly better auditory outcomes in short‐term and similar results in long‐term compared to double‐layered cartilage island graft with extra perichondrium. Cubism graft is a highly promising graft technique with its many advantages. Level of Evidence 1b.

impact of cubism graft on the outcome of tympanoplasty surgery

“…Cubism graft group was significantly higher than Temporalis fascia only group regarding ABG gain 3 month (p= 0.005). In agreement with the present study Kaya et al, 2021 found that there was no statistically significant difference in the preoperative ABG between study and control groups (P > .05). There were statistically significant differences in the postoperative first month ABG and ABG gain between study and control groups (P < .001).…”

“…The current study was in line with the study by Kaya et al, 2021 aimed to analyze the outcomes of a new graft technique in tympanoplasty and compare its outcomes with cartilage island graft plus extra perichondrium. The study included 44 patients were randomly divided into 2 double-layer graft groups: The cartilage island graft + cubism graft (study group) and the cartilage island graft + extra perichondrium (control group).…”

“…Tympanoplasty is a widely performed surgery for the repair of tympanic membrane perforation. The main goals of tympanoplasty are to get an intact tympanic membrane by closing the perforation area with a graft material and to improve the hearing (Khan and Parab 2016) (Kaya et al, 2021), we will compare the outcome of the current study with this study and some other studies describing different methods.…”

“…The study by Kaya et al, 2021 revealed that all the studied patient was operated by trans canal endoscopic approach. The graft success rate was 100% in the first month otological examination in the study group.…”

Comparative study between temporalis fascia graft with and without addittion of cyanoacrylate glue in myringoplasty

“…TM perforation is now treated with tissue adhesive-based myringoplasty, which is seen as a cutting-edge method (Azimi B et al, 2021). Since the 1980s, tissue adhesives have been used in ear surgery to hold the graft in place during tympanoplasty, act as scaffolding while vascularization takes place, and keep the area dry to prevent infection (Kaya et al, 2021). Research has shown that tissue adhesives help grafts take hold better (Bansal C et al,2020).…”
