Abstract:ObjectiveTo investigate the therapeutic effect of chronic suppurative otitis media on stationary phase with myringoplasty of different methods so as to provide reference for selection of proper surgical procedures.Methods212 patients suffering from tympanic membrane perforation repaired with myringoplasty were included. They were all followed up 3 months postoperatively. As for the size of perforations, 29 were small (<3 mm), 53 were moderate (3 mm~6 mm), 79 were large (>6 mm), and 51 were complete (without any remaining membrane). A variety of surgical methods were adopted according to the size of perforations, including repair with fatty tissues in 10 cases, underlay technique (via ear canal) in 13, wholeoverturn underlay technique in 31, combined underlay and overlay technique in 35, interlay method in 80, overlay technique in 14. Their therapeutic effect was evaluated 3 months after surgery by perforation healing rate and increase of puretone averages (PTA).ResultsPrimary healing got achieved in 203 cases with a healing rate of 95.7%. The differences of abovementioned indexes among different surgical methods for small, large and complete perforations were all statistically insignificant (all P>0.05). As for moderate perforations, the differences of perforation healing rate among three surgical methods were statistically insignificant (all P>0.05), but the difference of increase of PTA between combined underlay and overlay technique and interlay method was statistically significant(P<0.05).ConclusionSurgeons should master different methods of myringoplasty. In order to achieve the best recovery of function and restoration of tympanic membrane integrity, proper surgical method should be adopted according to the size and location of the tympanic membrane perforation, width and merit of external auditory canal.
