CONCLUSION
In order to improve the healing rate of large perforations, sub-total
perforations and marginal perforations in the anterior inferior
quadrant, we modified the traditional endoscopic cartilage myringoplasty
by adding an extra perichondrium or cartilage patch to the anterior
inferior edge of the perforation to enhance the contact between graft
and tympanic membrane remnant. The using of an extra patch achieved a
high healing rate and a statistically significant hearing gain. No major
complications were observed during follow-up period. While this method
improves the outcome of patients whose grafts did not well fit tympanic
membrane during operation, it does not significantly prolong the
operation time or increase the financial burden of patients, promoting
its potential to be popularized in clinical practice. The clinical
effectiveness and feasibility of this method can be further demonstrated
by expanding the sample size and prolonging the follow-up time.
