Perichondrial cartilage island graft tympanoplasty in chronic suppurative
otitis media with subtotal tympanic membrane perforation
Abasali Fahzadi
background: Wet tympanic membrane perforations especially of large sizes constitute a challenging subgroup of cases to repair. Attempts have been done to increase the success rate in the above circumstances and Cartilage is recently considered as an alternative to the most widely used graft material “temporalis fascia” , with acceptable functional and anatomical results.
Objective: this study aims to evaluate the anatomical and functional success rate of Perichondrial cartilage island graft tympanoplasty in this subgroup of patients.
method: 41 cases of chronic suppurative otitis media with subtotal TM perforations underwent mastoidectomy and perichondrial cartilage island graft tympanoplasty. Tragal cartilage was used as the donor site. The cases were followed from 7 to 38 months and anatomical and functional success was evaluated.
Results: After an average follow up period of 28 month Anatomical success (intact TM graft without perforation retraction or atrophy) was seen in 97.6% of cases. ABG reduced from 26.9 +/- 6.7 db preoperatively to 14.36 +/- 4.45 post operatively (Pvalue <o.oo1) and successful air bone gap closure was achieved in 92.7% of cases.
Conclusion: Perichondrial cartilage island graft can be a reliable alternative graft material for cases with chronic suppurative otitis media in whichtemporalis fascia is more prone to fail.
