What is an excisional biopsy?

1. Surgical removal of the frenulum

2. Wedge-shaped tissue excision

3. Surgical excision of the entire lesion for diagnosis

4. Inflammation of the tongue

The correct answer is: Surgical excision of the entire lesion for diagnosis

An excisional biopsy refers to a procedure in which an entire lesion is surgically removed for diagnostic purposes. This technique not only allows for a definitive diagnosis through histological examination but also aims to eliminate the lesion entirely if it is found to be problematic, such as in cases of cancer. By excising the whole lesion, the pathologist can assess the tissue in its entirety, looking for any signs of disease, which is crucial for determining treatment options and prognosis. The focus on removing the entire lesion distinguishes excisional biopsies from other forms of biopsies where only a portion of the tissue may be sampled, as can be seen in other techniques. This method is particularly important in cases where malignancy is suspected or the lesion presents concerning features. Understanding the role and function of an excisional biopsy is vital for those in the dental field, as it pertains to diagnosis and treatment planning for conditions that may affect oral health.
