Type 1 Tympanoplasty by Cartilage Palisade and Temporalis Fascia Technique: A Comparison

Abstract

(1) To compare graft take up of type-1 tympanoplasty with cartilage palisade technique with those of type-1 tympanoplasty using autotemporalis fascia. (2) To compare hearing results of type 1 tympanoplasty with cartilage palisade technique with those of type-1 tympanoplasty using autotemporalis fascia. A prospective clinical study. It consisted of 60 patients divided into two groups of 30 patients each. After randomization 30 patients underwent type 1 tympanoplasty using cartilage palisade technique and 30 underwent type 1 tympanoplasty using autotemporalis fascia. In follow up, pure tone audiogram were carried out at 2nd, 4th and 6th month. Clinical assessment was done at 2nd 4th and 6th month. The graft uptake rate between the group 1 and group 2 are 93.33 and 90% respectively. As value was greater than 0.05 so statistically there is no significant difference between the two group. The post operative air bone gap of the two groups were compared using student test. The pre op mean of group 1 was 32.5 db and pre op mean of group 2 was 30.66 db. The post op mean of group 1 was 21.33, with standard deviation of 3.6984 and standard error of 0.67523. The post op mean of group 2 was 21.09 with standard deviation of 3.29 and standard error of 0.58261. t value was 0.1357. Analysis was done using student test and value was found to be greater than 0.05. value is greater than 0.05 which shows that there is no statistical difference between the two groups. This study establishes the fact that hearing results after performing type 1 tympanoplasty by autotemporalis fascia when compared with type 1 tympanoplasty performed by cartilage palisade technique showed similar hearing gain and post operatively graft take up rate was also similar in two groups. The disadvantage of reducing the mechanical vibration of the tympanic membrane was overcome by the palisade reconstruction of the tympanic membrane. This study definitely emphasizes upon usage of new grafting materials in reconstruction of tympanic membrane, with similar, if not better functional results, without compromising the acoustic transfer characteristics.

A comparative study of preoperative and postoperative hearing after type I tympanoplasty using temporalis fascia graft at Dr. B. R. Ambedkar Medical College, Bengaluru

“…6 Arora et al published a study on comparison between type 1 tympanoplasty by cartilage palisade and temporalis fascia technique. 7 With temporalis fascia technique, the number of successful graft uptakes was similar to ours, with 27 cases out of 30 (90%) showing successful graft uptake.…”

“…[2][3][4] However, there is still controversy about which repair material and technology are best. [5][6][7][8] This study aimed to compare the results of different graft materials in type I tympanoplasty for patients with large tympanic membrane perforations.…”

Long-term results of type I tympanoplasty with perichondrium reinforced cartilage palisade vs temporalis fascia for large perforations: A retrospective study

“…Arora et al. had an uptake of 93% with fascia and 90% with palisades at six months follow-up in a prospective randomized study ( Arora et al., 2017 ). These studies have higher uptake rates than ours, but over very short follow-up periods.…”
