Oral Mucosal Biopsy + Pathology

Biopsy is usually performed under local anesthesia, selecting representative or boundary areas for sampling, and positioning with the aid of an oral endoscope or optical imaging if necessary. The removed tissue is placed in a fixative and sent to the pathology department for routine sectioning and staining, with immunohistochemistry or molecular testing added as needed. The surgical area is controlled for bleeding by compression, suturing, or hemostatic materials, and oral hygiene is instructed. Postoperative focus is on observing bleeding and infection, with the goal of obtaining a clear diagnosis to guide subsequent treatment. The above is general health information, not medical advice; the specific plan is subject to specialist evaluation and hospital protocol.
