[The effectiveness of endoscopic tragus cartilage-perichondrium myringoplasty in the treatment of large tympanic membrane perforations].

OBJECTIVE

To evaluate effectiveness of endoscopic tragus cartilage-perichondrium in the treatment of large tympanic membrane perforations.

METHOD

Patients with large tympanic membrane perfortations who had underwent cartilage-perichondrium myringoplasty were retrospectively retrieved from our department. Those with a follow-up of equal to or greater than 12 months after surgery were included in the study. Hearing test results were reported using a four-frequency air conduction and bone-air conduction gap. Patients were labeled as treatment success if the tympanic membrane was intact without lateralization or anterior blunting after surgery.

RESULT

Of the 35 patients with large tympanic membrane perforations treated by endoscopic tragus cartilage-perichondrium, 33 (94.3%) were treatment success. There was no graft lateralization, anterior blunting, neocholesteatoma, and sensorineural hearing loss in these patients after surgery. The air conduction and bone-air conduction gap before surgery in the study cohort were (43.8 ± 5.7) dB and (28.5 ± 3.1) dB, respectively. Postoperative air conduction and bone-air conduction gap of the cohort were (31.4 ± 6.4) dB HL and (16.2 ± 4.1) dB, respectively. The postoperative air conduction and bone-air conduction gap decreased significantly after surgery (P < 0.01). Overall postoperative air-bone gap in 27 of the 35 patients (77%) were less than 20 dB after surgery.

CONCLUSION

Endoscopic cartilage-perichondrium myringoplasty is an effective procedure in the treatment of large tympanic membrane perforations.
