Oral cavity biopsy
Oral cavity biopsy
Open biopsy
This is the initial diagnostic method for examining masses in the mouth. It involves taking a small sample of the mass to obtain enough material to help determine whether the nodule is benign or malignant.
The oral cavity biopsy procedure is performed on an outpatient basis and has a diagnostic accuracy of over 95%. Usually, small amounts of topical anesthesia are used.
The person remains seated. The biopsy site is sterilized with an iodine solution and then topical anesthesia is applied and left to take effect for a few minutes. Then, a sample is taken with special biopsy forceps. You may feel pressure and a pulling sensation. Gentle pressure is applied to the site for two minutes to control bleeding. This procedure takes approximately one minute. It is usually necessary to perform a second and even a third biopsy during the same procedure to obtain sufficient material. After the oral cavity biopsy, the patient will have a plaque that may be painful and sensitive for a few days.
No preparation is necessary for this biopsy. Most people report mild, short-lived pain and minimal bleeding that can be controlled with pressure. There is a very low risk of bruising or infection, which can usually be treated with common painkillers, oral antibiotics, and local measures. The sample obtained is processed by an expert pathologist, which takes approximately two weeks. The results of the oral cavity biopsy must be interpreted by a head and neck surgeon.
