Comparison of tragal perichondrium with cubism graft in endoscopic tympanoplasty in small- to medium-size tympanic membrane perforations

Background Cubism graft technique offers controlled thinning of the cartilage and prevents over-curling. This article compares tragal perichondrium with the new cubism graft in tympanoplasty in small- to medium-size tympanic membrane perforations.Methodology In our study, we included 40 patients, where tragal perichondrium was used as a graft in 20 patients, while cubism graft with tragal cartilage was used in the other 20 patients.Results Only two patients had a failure in graft uptake in the tragal perichondrium group, while three patients had a failure in graft uptake in the group where cubism graft with tragal cartilage was used. Significant closure of the air-bone gap (>= 9 dB) was observed in post-operative audiogram at three-month follow-up in both groups.Conclusion This study concludes that the new cubism graft is comparable to tragal perichondrium graft in terms of graft uptake and closure of the air-bone gap.
