ObjectiveTo investigate the clinical efficacy of repairing tympanic membrane perforation with different types of tragus cartilage-perichondrium under otoendoscope.
MethodsSixty patients (60 ears) who underwent endoscopic surgery were randomly divided into the control group (n=30) and the observation group (n=30).In the observation group, the perforation of tympanic membrane was repaired by semi-thick island of tragus cartilage-perichondrium complex.All patients were followed up for 6-12 months.The healing of tympanic membrane and hearing improvement were compared between the two groups.
ResultsThe healing rate of tympanic membrane in the observation group was 100.0% (30/30), which was higher than 80.0%(24/30) in the control group (P < 0.05).There was no significant difference in the air-conductance threshold and air-bone conductance difference between the two groups before operation (P>0.05).The air-conductance threshold and air-bone conductance difference of the observation group were significantly better than those of the control group (P < 0.01), and the intra-group comparison showed that the air-conductance threshold and air-bone conductance difference of the two groups after operation were significantly better than those before operation (P < 0.01).
ConclusionsIt is feasible to repair the perforated tympanic membrane under otoendoscope, especially the semi-thick island of auricular cartilage-perichondrium complex, which has a high survival rate, can repair the perforation of tympanic membrane of different sizes, and is beneficial to improve hearing, and the postoperative hearing improvement effect is good.
