Therapeutic Effect of Multiple Paper Patching for Traumatic Tympanic Membrane Perforation-Trial of Quantitative Analysis Using Image Analyzer / 대한이비인후과학회지

ABSTRACT

BACKGROUND AND OBJECTIVES: Paper patching for the treatment of traumatic tympanic membrane perforation is a safe, simple, and inexpensive method. This study was designed to evaluate the therapeutic effect of proper paper-patch techniques for traumatic tympanic membrane perforation using more objective measurement of perforated area by image analyzer. SUBJECTS AND METHOD: A prospective study of paper-patch techniques was carried out on 55 patients with traumatic perforations of the tympanic membrane. Objective semiquantitative measurement of the perforated area was performed using computerized image analyzer. Immediate eversion of inverted flaps and single to multiple patching techniques were used in all cases. Treatment results were analyzed according to various variables which may affect the healing rate. RESULTS: The closure rate of tympanic membrane with this paper patching method was 98.2% and the mean healing time was 2.9+/-1.9 weeks. Hearing impairment was correlated with the size of perforation which was measured quantitatively by image analyzer and the healing rate was decreased with infectious signs such as otorrhea. There were no side effects or complications. CONCLUSION: Multiple paper patching with proper technique for traumatic tympanic membrane perforation produced an excellent success rate and could be considered as part of initial therapeutic methods for all cases of large perforation with inverted flap.
