“…In our series the 0.5 mm thinned cartilage graft did not adversely affect acoustic transfer and was effective in preventing retraction. A novel study using Doppler interferometer and cadaver cartilage by Zahnert et al [26] confirms that a cartilage thickness of 0.5 mm to be a good compromise between sufficient mechanical stability and low acoustic transfer loss. The rate of re-retractions after cartilage tympanoplasty is reported to be low and would reflect our one ear (2 %) reretraction rate [20].…”

Evaluate the surgical treatment of tympanic membrane (TM) retractions with modified cartilage augmentation tympanoplasty. Retrospective review of subjects with Charachon stage II and III TM retractions who underwent modified cartilage augmentation tympanoplasty following excision of the retracted TM segment. Pre and postoperative symptoms and air-bone gaps were recorded. Forty two ears were included in the study. Twenty six ears were of stage II and 16 were stage III retractions. 35 (83 %) ears had ossicular erosion and cholesteatoma was found in 13 (31 %) ears, all in stage III retractions. Follow-up ranged 12-102 months. The air-bone gap (ABG) improved in 29 (76 %) and worsened in seven (19 %). Ears without cholesteatoma had a greater improvement in ABG. The results of our modified cartilage tympanoplasty technique are comparable to the published literature and should provide a safe and acceptable result. The high rate of cholesteatoma found preoperatively in stage III retractions advocates early surgical intervention.

“…Though it does not hamper the aeration through eustachian tube, it might be restricting the movement on tympanic membrane at 4k. Cartilage has lower compliance than fascia and hence, sudden pressure variations may not be well regulated with a more rigid tympanic membrane [6,25]. The rigidity of the cartilage graft has some benefits in reducing retraction of the tympanic membrane; however, it is unclear if the increase in rigidity and mass reduces the sound conduction properties of the graft.…”

To evaluate the success rate, in terms of anatomical and functional results, in our technique of cartilage support for fascia graft in type I tympanoplasty. Retrospective study of tragal cartilage support for fascia graft in tympanoplasty for large central perforation in 748 patients was carried at an academic institution during January 2004 to March 2012. Patients' age ranged from 11 to 65 years. 325 (43.4 %) male and 423 (56.6 %) female patients were operated and mean post-operative follow up was of 24 months (range 6-48 months). The inclusion criteria were large central or subtotal perforation, anterior quadrant perforation, anterior tympanosclerotic patch with perforation and revision myringoplasty. Small central perforation, posterior perforations, traumatic perforations and Ossiculplasty were excluded from this study. In this technique, a piece of tragal cartilage carved in semi lunar shape is inserted medial to anterior remnant of tympanic membrane. Temporalis fascia graft is sandwiched between cartilage and anterior remnant of tympanic membrane. Post-operative closure of perforation was noted. Pure-tone average pre and post-operative air-bone gap in dB at 250, 500, 1000, 2000, and 4,000 Hz were compared. The overall success rate of our technique was 98.3 % in terms of graft uptake and within 13.35 ± 5.22 dB of air bone gap closure in terms of hearing improvement. This study reveals that cartilage support for fascia graft in type I tympanoplasty is a highly reliable technique and gives significant improvement in graft take-up and hearing status.

“…Nonetheless, the cartilage acoustic transfer characteristics are theoretically worse because of its thickness 2,4,6 . In 2000, Zahnert et al carried out an experimental study concluding that a 500μm-thick cartilage has an acceptable acoustic transfer capacity with good mechanical stability 14 .…”

The treatment of tympanic membrane perforations in the pediatric population with sequelae of chronic otitis media represents a challenge to otolaryngologists. Aim: to assess the clinical and audiometric results of the inlay technique with a tragus cartilage plug. Materials and Methods: we assessed 23 patients (ages between 1 and 15 years) who underwent plug tympanoplasty. Study design: clinical retrospective. Results: repair success rate was of 82.6%, with audiometric parameters improvement in 87.5% of the patients. Complications were minimum. Conclusion: considering the results attained, this method of tympanoplasty should be considered a good treatment option for tympanic membrane perforation in children.
