ABSTRACT
Abstract. This article presents a systematic evaluation of the effectiveness of type 1 tympanoplasty in patients with chronic tubotympanic suppurative otitis media, accompanied by a tympanic membrane perforation exceeding 50% of its surface area. The primary success criteria of the procedure are graft take rate (GTR) and restoration of auditory function assessed through changes in the air-bone gap (ABG). The analysis included studies evaluating the anatomical and functional outcomes of tympanoplasty using various autologous graft materials, such as fascia and cartilage. The predominant graft placement technique was the underlay technique. The weighted average preoperative ABG was 25.31 dB, while the postoperative ABG was 11.09 dB, indicating significant improvement in auditory function after surgery. Comparative analysis of the effectiveness of different graft materials showed that the use of cartilage resulted in higher graft take rates (92.6%) compared to fascia (88.6%). However, the differences in hearing improvement between cartilage and fascia were statistically insignificant (p > 0.05). The analysis presented in the article indicates high reliability of the obtained results, as evidenced by the low heterogeneity of the studies and the absence of publication bias.
