Audiological and otological outcome in Bi-island chondroperichondrial graft type I tympanoplasty

Abstract

Background: The principal aims of a tympanoplasty operation are to create an intact tympanic membrane and to restore an optimal hearing improvement. Many surgeons have used cartilage for grafting due to its increased stability and resistance to negative pressure. Cartilage has been criticized because of concerns regarding hearing results.Objectives: The aim of this study is to present the experience of using cartilage for grafting central perforations in type I tympanoplasty procedure with some novel modifications and evaluate its take rate and audiologic results.Methods: This is a prospective study including 40 patients (45 ears) who underwent type I cartilage tympanoplasty. All patients are primary cases of chronic suppurative otitis media of tubotympanic type. The following parameters were evaluated at least after 3 months from surgery: graft take and change between the pre-and post-operative pure-tone average air-bone gap (PTA-ABG).Results: Thirty-nine patients included in the study underwent 45 cartilage tympanoplasty type I operations. The mean age of the patients was 24.9 ± 9.5 years (range, 15-51 years). The mean follow up period was 6.2 months (range, 3-9 months). All perforations were found to be closed with a 100% graft take rate. The overall mean pre-operative PTA-ABG was 26.0 ± 4.4 dB, whereas the postoperative PTA-ABG was 13.8 ± 5 dB (p < 0.0001) which is highly significant. The percent of reduction of PTA-ABG was about 46.6%.Conclusion: Bi-island chondroperichondrial type I tympanoplasty is an effective and reliable technique with a high success rate and minimal complications.

Tympanoplasty Type-I using tragal perichondrium graft: Our experience

“…In this study among 36 patients 21 (58.3%) were male and 15 (41.7%) were female with male: female ratio of 1.4:1, that is consistent with results of Subramania2 with 42 (52.55%) males, 38(47.5%) female and male: female ratio of 1.1:1, and Dhanapala with 57 (57%) males, 43(43%) female and male: female ratio of 1.3:1 11. However this study results regarding gender distribution differs from Vaishali, Hasaballah and Gupta having female predominance as female 55% male 45%, females 66.6% males 33.4% and females 70% males 30% respectively 3,5,12. In current study mean ± SD age was 27.14 ± 7.49 years, with age range 15 – 50 years and patients presented commonly in 3 rd and 4 th decade of life i.e.…”

“…Similarly in Pareek’s study mean ± SD age of the patient was 26.23 ± 12.46 years with age range of 10 to 60 years 13. Hasaballah observed that mean ± SD age was 24.9 ± 9.5 years with age range 15–51 years 12. Vaishali also reported that mean age of patients was 29.12 years (range, 15–45 years) and majority of patients (40%) were in 3 rd decade of life 3.…”

Cartilage Graft in Myringoplasty: What Are the Factors Influencing Hearing Gain?

“…This type of graft feeds by diffusion from the surrounding tissue such as the perichondrium and tympanic-meatal flap and is easily integrated into the tympanic membrane due to its flexibility. Its rigid character makes it robust and resistant to resorption and retraction under prolonged pressure [7][8][9][10]. This resistance is more marked when the cartilage is grafted with its perichondrium [9,10].…”
