**Question:** Tylectomy literally means

A. removal of a tongue
B. removal of a tooth
C. removal of a thyroid gland
D. removal of a testicle

**Core Concept:** Tylectomy is a surgery or medical intervention that involves the surgical removal of the tongue (glossopharyngectomy).

**Why the Correct Answer is Right:** Tylectomy is the correct answer because it directly refers to the surgical removal of the tongue, which is a crucial part of the oral cavity and plays a vital role in speech, swallowing, and sensation.

**Why Each Wrong Option is Incorrect:**

A. Removal of a tooth (odontotomy) is not the same as tylectomy, as it pertains to the surgical removal of a tooth, not the tongue.

B. Removal of a tooth is not the same as tylectomy, as stated above.

C. Removal of a thyroid gland (thyroidectomy) is a different surgical procedure targeting the thyroid, not the tongue.

D. Removal of a testicle (orchidectomy) is unrelated to the tongue and does not represent the correct surgical intervention in this context.

**Clinical Pearl / High-Yield Fact:** When performing a tylectomy, it is essential to consider the potential complications, including dysphagia (difficulty swallowing), dysarthria (speech difficulties), and microstomia (tight mouth opening). These complications can lead to impaired oral functions and affect the patient's quality of life.

**Correct Answer:** A. removal of a tooth (odontotomy)
