Objective: To assess the efficacy of butterfly inlay cartilage tympanoplasty and compare it with conventional underlay cartilage tympanoplasty in terms of success rate and hearing outcomes.
Materials And Methods: The study included 35 patients (36 ears) who underwent butterfly inlay cartilage tympanoplasty (inlay group, 23 ears of 22 patients) or conventional underlay cartilage tympanoplasty (underlay group, 13 ears). The anatomical success rate and hearing outcomes were analysed.
Results: Re-perforation occurred in 2 cases (8.7%) in the inlay group and 3 (23.1%) in the underlay group. One patient in the inlay group developed a serious infection, and one in the underlay group developed massive granulation of the tympanic membrane. In the inlay group, the air-bone gap (ABG) decreased from 19.9 (±12.6) dB HL preoperatively to 13.8 (±11.3) dB HL postoperatively (p=0.047), in the underlay group, it decreased from 23.5 (±15.8) dB HL to 18.3 (±20.6) dB HL. Regarding improvement in ABG, the difference between the group was not statistically significant (p=0.968).
Conclusion: Butterfly inlay cartilage tympanoplasty is comparable with conventional underlay cartilage tympanoplasty in both anatomic and audiological success rates. Owing to its simplicity, shorter operation time, and rapid patient recovery, butterfly inlay cartilage tympanoplasty could be considered a favourable surgical option.

Objective: The butterfly cartilage inlay technique was originally developed for repairing small tympanic membrane (TM) perforations but is now increasingly used for repairing large TM perforations. Although studies have evaluated the effectiveness of butterfly tympanoplasty for repairing medium-to-large-sized TM perforations, no study has compared its effectiveness with that of the conventional underlay cartilage technique. Therefore, we aimed to evaluate the effectiveness of butterfly tympanoplasty for repairing medium-to-large-sized TM perforations compared with that of the conventional underlay cartilage.

Objective: This study aimed to assess the efficacy of a novel modified asymmetric chondro-perichondrial island graft in tympanoplasty. The design features a longer anterior segment compared to the posterior segment, addressing limitations of symmetrical grafts. We investigated the impact of this modified graft on hearing improvement and graft success rates in patients undergoing tympanoplasty surgery.

In this study, the graft success and hearing improvement were compared in patients with subtotal or total tympanic membrane perforations following conchal cartilage-reinforced temporalis fascia graft tympanoplasty (CCRTT) versus traditional tragal island cartilage tympanoplasty (TICT). Fifty Type 1 tympanoplasties performed for subtotal or total tympanic membrane perforation were classified into 2 groups: CCRTT consisted of 23 patients and TICT consisted of 27 patients. The difference between these 2 groups was analyzed by means of graft success, reperforation, and postoperative hearing gain after 12 months.

Purpose: This study aimed to compare the hearing outcomes of patients who underwent different type 4 tympanoplasty techniques.
Methods: Patients who underwent tympanoplasty for chronic otitis media and were treated with cortical bone total ossicular prosthesis supported with crescent-shaped cartilage (Group 1), cortical bone total ossicular prosthesis (Group 2) and titanium total ossicular prosthesis (Group 3) were included in the study. Hearing outcomes were evaluated and compared with audiological tests performed before and at least 1 year after surgery.

Retrospective analysis of clinical data of 123 patients with atticotomy, exploring the clinical characteristics of patients undergoing atticotomy and the efficacy of hearing reconstruction methods. 123 patients with atticotomy were divided into three groups according to the ossicular chain treatment method: preservation of the ossicular chain group（37 cases）, cartilage elevation of stapes group（49 cases）, and PORP group（37 cases）. The clinical characteristics of patients with atticotomy, preoperative and postoperative hearing levels of the three groups of patients, and postoperative complications were analyzed.
