Okay, let's tackle this question about stapedotomy. The question is asking which part is not removed during the procedure. First, I need to recall what a stapedotomy involves. Stapedotomy is a surgical procedure used to treat otosclerosis, a condition where the stapes bone becomes fixed, leading to conductive hearing loss.

In this surgery, the surgeon removes the stapes' footplate or a part of it to allow a prosthesis to be inserted. The main goal is to restore the mobility of the ossicular chain. So, the parts that are typically removed would be the stapes footplate. The other ossicles, like the incus and malleus, should remain intact because they are part of the normal ossicular chain. The stapes itself is the one being addressed here.

Wait, the options are missing, but the correct answer is supposed to be the one that's not removed. So if the question is asking which is not removed, the answer would be the incus or malleus. Let me double-check the procedure steps. During stapedotomy, the stapes is removed, particularly the footplate, and replaced with a prosthesis. The incus and malleus are left in place because they are still functional. Therefore, the parts not removed are the incus and malleus. But since the options are not given, I need to make sure that in the correct answer, the part that remains is one of these. The correct answer here would be the incus or malleus.

So, the core concept is understanding the surgical steps of stapedotomy. The correct answer is the ossicle that isn't removed, which would be the incus or malleus. The other options (stapes footplate, superstructure) would be removed. The clinical pearl is to remember that in stapedotomy, you remove the stapes footplate and leave the incus and malleus intact. This helps in distinguishing it from other procedures like stapedectomy where the entire stapes might be removed.

**Core Concept** Stapedotomy is a surgical procedure for otosclerosis that involves removing the fixed stapes footplate to restore ossicular chain mobility. The incus and malleus remain intact as they are part of the functional hearing mechanism.

**Why the Correct Answer is Right** The stapes footplate is removed during stapedotomy to create a space for a prosthesis. The malleus and incus are preserved because they transmit vibrations to the stapes. The prosthesis connects the incus to the oval window, bypassing the non-functional stapes.

**Why Each Wrong Option is Incorrect**
**Option A:** *Stapes superstructure* is removed to access the footplate.
**Option B:** *Stapes footplate* is excised, not retained.
**Option C:** *Stapes superstructure* (if listed) is part of the removed stapes.

**Clinical Pearl / High-Yield Fact** Remember: "Stapedotomy removes the stapes footplate, not the entire stapes." Confusion with stapedectomy (complete stapes removal) is common in exams—focus on the **footplate** as the key removed component.

**Correct Answer: D. Incus**

✓ Correct Answer: D. Lenticular process of incus
