Before offering any suggestions, I'd be wanting to know what investigation has been done as to why this has occurred. Did you follow your surgeons post-op dilation procedure? If yes and this caused issues, were they discussed with the surgeon? If no, why not? This is part of what the dilation regimen is intended to prevent.
I'd be wanting to know why it requires a revision, as, outside of failure to dilate, the other options are likely to cause similar issues for any further surgeries.
