CONCLUSION
Swing-door overlay tympanoplasty showed good surgical outcomes in terms
of graft uptake rate regardless of gelfoam packing. However, our
prospective randomized controlled study showed earlier hearing
improvement and faster healing process in NGPG, thereby indicating that
the gelfoam in the middle ear may interfere with the healing process of
neodrum and middle ear cavity. Consequently, it is proposed that
surgical technique without AGS during middle ear surgery should be
considered based on the advantages of the faster healing process and
better hearing results.
