Assessment and spontaneous healing outcomes of traumatic eardrum perforation with bleeding.

Abstract

OBJECTIVE:

This study investigated the influence of the degree of bleeding from the remnant eardrum on the spontaneous healing of human traumatic tympanic membrane perforations (TMPs).

STUDY DESIGN:

A case series with chart review.

SETTING:

A tertiary university hospital.

MATERIALS AND METHODS:

The clinical records of traumatic TMP patients who met the case selection criteria were retrieved and categorized into two groups based on the documented degree of bleeding from the remnant eardrum: with and without bleeding. The demographic data and spontaneous healing outcomes (i.e., healing rate and duration) of these two TMP types were analyzed using the chi-squared test or t-test.

RESULTS:

One-hundred and eighty-eight cases met the inclusion criteria and were analyzed. Of these, 58.5% had perforations without bleeding and the remaining 41.5% had perforations with bleeding. The overall closure rate at the end of the 3-month follow-up period was 90.9% for perforations without bleeding and 96.2% for perforations with bleeding; the difference was not statistically significant (P>0.05). However, the average closure time differed significantly between the two groups (P<0.05): 29.4±3.7days for perforations without bleeding and 20.6±9.2days for perforations with bleeding. The closure rate was significantly different between the groups (62 vs. 15.6%, P<0.01) within 2weeks for medium-sized perforations. In total, 11 (39.3%) large-sized perforations achieved complete closure in the group with bleeding, while none of the large-sized perforations closed in the group without bleeding within 2weeks. The closure rate of medium-sized perforations was not significantly different (79.2 vs. 92%, P>0.05) between the groups without and with bleeding within 4weeks, while the closure rate of large-sized perforations was significantly different between the groups without and with bleeding (27.2 vs. 75%, P=0.0).

CONCLUSION:

This study shows that traumatic TMPs with bleeding significantly shortened the closure time compared to TMPs without bleeding. This finding indicates a significant correlation between the prognosis of traumatic TMPs and the degree of eardrum bleeding: severe bleeding from and a hematoma in the remnant eardrum appear to be good signs.
