Ear tubes after age 5?

My daughter had her cleft lip repaired at 5 months and her cleft palate repaired at 11 months. During the cleft palate repair, ear tubes were also placed.

At about age 2, one of the tubes fell out and the ENT recommended replacement of both, which we did.

At some point in the last year or so, the tube on the same side (non cleft-affected side) fell out again. We've had intermittent follow ups and hearing tests since then. The hearing tests show very slight/mild "hearing loss" due to some fluid in the middle ear within the ear that the tube has fallen out of. The ENT explained the frequency that is impacted is not near the level that people converse at. She passed all the tests where she had to indicate when she could hear the test sounds.

While not being pushy, the ENT is recommending replacement ear tubes again. I know they want to reduce any possible chance for hearing loss, which I of course support. But she has had no trouble with speech (her speech is well understood and comparable to other peers her age, per SLP assessments) and she shows no signs of difficulty hearing.

How many times are we going to have to go through this? I know ear tube placement is so quick and easy of a procedure, but my kiddo has already undergone anesthesia many times already and that isn't risk-free (a good friend of mine is a nurse anesthetist so we've talked about it), and there are going to be more surgeries and procedures down the line. Can I expect that these tubes are just going to keep falling out every few years and need replacement each time? At what age can I expect them to stop this recommendation if the hearing test results end up like this every time they check?

Just want to hear from others on their experiences and deciding what to do. I of course want to do what's best for my kid and I highly value and generally follow medical experts advice. But I feel on the fence about this.
