Sinonasal Undifferentiated Carcinoma Orange County

Sinonasal Carcinoma Newport Beach & Orange CountySinonasal carcinoma is a malignant or cancerous tumor of the nose and sinuses and comes in different types. These tumors are rare, making up only about three percent of tumors in the upper respiratory tract. They are known to occur twice as common in males than in females. The different types of sinonasal carcinoma are:


  • Basal cell and squamous cell carcinoma
  • Adenocarcinoma
  • Adenoid cystic carcinoma
  • Sinonasal undifferentiated carcinoma (SNUC)
  • Esthesioneuroblastoma
  • Sarcomas (arising from soft tissue, cartilage, and bone)
  • Melanoma
  • Lymphoma


There is no known direct cause for sinonasal carcinoma. However, it is sometimes associated with squamous cell carcinoma and cigarette smoking. Sinonasal carcinoma occurs more commonly among middle-aged men and those exposed to leather tanning, industrial fumes and minerals (nickel, cadmium), and wood dust.

Symptoms of sinonasal carcinoma vary depending on the location of the Sinonasal Tumor in Newport Beach. The most common symptoms are nasal congestion and discharge. Symptoms from other benign conditions such as allergies or sinusitis can delay the diagnosis of a malignant sinonasal carcinoma. Below are the common symptoms:

  • Difficulty breathing through one side of the nose
  • Loss of sense of smell
  • Nasal bleeding
  • Nasal obstruction (usually on one side only)
  • Facial pressure, swelling, or pain
  • Bulging eye
  • Confusion
  • Double vision or visual loss
  • Tearing
  • Loosening or numbness of the upper teeth


In advanced sinonasal carcinoma, patients may be presented with more serious symptoms:

  • Loss of hearing or ear pain
  • Headache
  • Difficulty opening the mouth
  • Mental status change

Initial sinonasal carcinoma treatment in Newport Beach for sinonasal carcinoma will involve Robert Louis, MD conducting thorough medical history and physical exam, including the patient’s symptoms and health history. To help diagnose and confirm the presence of a colloid cyst, special imaging will be requested:

Endoscopic examination: Initial endoscopic examination by an otolaryngologist or an ENT doctor.

Magnetic resonance imaging (MRI): An MRI uses magnetic fields to produce detailed cross-sectional images of the brain.

Computed tomography (CT) scan: Imaging procedure that uses X-ray camera to scan series of detailed cross-sectional images of the brain.

Biopsy: A procedure where a small piece of tumor tissue is removed and tested to confirm sinonasal carcinoma.

After diagnostic tests are done, Dr. Louis will review all of the results with you and describe the tumor location, size and the best treatment options.

Treatment of sinonasal carcinoma is planned for each individual case and depends on the type, size, and location of the tumor. Combination treatment with minimally invasive keyhole surgery and radiotherapy, with or without chemotherapy, is given in specific situations.

Endonasal Endoscopy:
A minimally invasive keyhole approach that allows an endoscope to be threaded through the nose and sinus to reach and remove sinonasal carcinoma. Robert Louis, MD specializes in minimally invasive removal of sinonasal carcinoma which is proven to be safer and more effective. It incorporates Dr. Louis’ experience, education training, and use of cutting-edge technology and instrumentation.

Radiation Therapy
When it is not possible to operate or remove the sinonasal carcinoma completely and safely, radiation is the best treatment option.

Chemotherapy uses drugs to stop cells of sinonasal cancer in Newport Beach from growing. Depending on the type and stage of the sinonasal carcinoma, chemotherapy may be taken by mouth, injected, or placed directly into the tumor site.
