I’ve had that experience of a dome coming out. The safest thing to do would to just be patient and see your HCP. My wife is a doctor and routinely examines her patients’ ears with an otoscope. So I trust her to remove a dome stuck in my ear that way. I laid my head sideways down on a table to be as immobile as possible, ear with the stuck dome up. I gave her a fine-tipped but blunted forceps. She could see the dome and knew from her medical experience that she was nowhere near my ear drum and she could easily latch onto the dome and pull it out. Unless you have an experienced person as an assistant, it probably would not be a good idea to give them on-the-job training…
That’s one advantage of wearing molds. The type I wear are cast with small discrete plastic pull rods, one for each ear. You don’t have to pull on the receiver wire, just the tiny knobbed rod or thread attached directly to each mold. So there is essentially no danger of the mold coming off the receiver in your ear.
Also, something else that helps with both domes and molds. If, as you are slowly and gently pulling the receiver out of your ear by whatever means is appropriate for dome or mold, with your other hand reach up to the top of your ear lobe and gently pull the back top of your ear lobe up and slightly away from the side of your head. This may open up your ear canal a bit and ease the removal of the receiver and mold or dome combination. I find varying the amount of tension on the ear lobe more helpful than just pulling steadily with a certain tension helps to find the “Goldilocks” amount of tension on the ear lobe that helps do the job.
P.S. The other thing about messing around with the inside of your ear and inserting and removing receivers is that you want to be reasonably gentle and careful doing it. From what I’ve read, abrading the inside of your ear canal by putting your finger or Q-tips into your ear canal or being too rough inserting or removing your HA’s is a major cause of ear infections by making your tissue more accessible to infectious agents that are naturally present in your ear canal and the environment all the time (just like getting a cut on your skin surface infected).
