Oral Cancer

Oral cancer, also known as mouth cancer, is a type of head and neck cancer and is any cancerous tissue growth located in the oral cavity.

It may arise as a primary lesion originating in any of the tissues in the mouth, by metastasis from a distant site of origin, or by extension from a neighboring anatomic structure, such as the nasal cavity. Alternatively, the oral cancers may originate in any of the tissues of the mouth, and may be of varied histologic types: teratoma, adenocarcinoma derived from a major or minor salivary gland, lymphoma from tonsillar or other lymphoid tissue, or melanoma from the pigment-producing cells of the oral mucosa. 


Salivary Gland Tumors

Salivary gland tumors and cancers represent a rare and diverse group of diseases. There are approximately 45 different types and this classification of salivary tumors is constantly changing. Grading of salivary tumors can be important the several types have both high grade and low grade histology (eg mucoepidermoid carcinoma). This can correlate with prognosis and will help the surgeon to select the appropriate treatment plan. It is essential that your surgeon understands the complexities of salivary gland tumors and has the necessary training to properly treat your disease.


Salivary Gland Disease

The salivary glands are divided into two distinct types, the major glands (Parotid, Submandibular, Sublingual) and the minor glands. Salivary gland disease can affect any of the salivary glands. Dr. Schlieve is trained in the diagnosis and management of salivary gland diseases. He is able to perform minimally invasive salivary gland interventions using a technique known as sialoendoscopy where a very small camera and instruments are used to restore the health of your salivary gland.


Tumors of the Jaws

Jaw tumors and cysts may appear as swelling in the jaws, which may be asymptomatic. If present, they may enlarge and can produce an aching sensation and/or swelling in the area. In certain areas, the swelling can apply pressure to nerves that can produce numbness, tingling or other sensations. There are many different types of cysts and tumors that occur in the head and neck.



The ameloblastoma is an aggressive benign odontogenic (meaning it originates from the tissues that grow tooth structures) tumor of the jaws. There are six different subtypes: Follicular, Plexiform, Acanthomatous, Granular cell, Basal cell, and Desmoplastic. In addition to the 6 subtypes, there are 3 main types of Ameloblastoma: Solid / Multicystic, Unicystic, and Peripheral.



Lichen Planus and Other Oral Diseases

Oral lichen planus is an ongoing (chronic) inflammatory condition that affects mucous membranes inside your mouth. Oral lichen planus may appear as white, lacy patches; red, swollen tissues; or open sores. These lesions may cause burning, pain or other discomfort.


Jaw Reconstruction and Tooth Replacement

Sometimes jaw problems may require more than orthodontic treatment. Jaw surgery, also known as orthognathic surgery, can be a great choice for moderate to severe jaw issues. If you are missing one or more teeth, there are several options for replacement teeth.
