Endoscopic Laser Surgery
Smoking is a risk factor for voice, box cancer, which most commonly affects the vocal cords (glottis). The area above the vocal cords (supraglottis) it’s only involved in a third of the cases or not until the cancer has grown very large. Approximately 12,000 people with voice box cancer are diagnosed in the US every year.
Symptoms
There are a number of symptoms that are associated with voice box cancer, which include:
- Hoarseness (any hoarseness persisting longer than three weeks should be evaluated by an ENT)
- Sore throat
- Pain radiating to the ear
- Coughing up blood
- Lump in neck
Treatment
Voice box cancer it’s categorized into 4 stages, which take the size and location of the tumor into consideration but also the possible spread to lymph nodes in the neck and other places in the body. Surgery, radiation and chemotherapy are general treatment considerations.
Endoscopic laser surgery can be considered for many voice box cancers, especially early-stage glottic cancers. Dr. Weidenbecher is an expert in minimally invasive surgery for voice box cancer. He often uses a KTP-laser (potassium titanyl phosphate laser) in conjunction with a microscope to gently remove the cancer while preserving as much of the normal vocal cord tissue as possible to maintain the best possible voice postoperatively.
Recent research has shown that laser surgery is the preferred treatment for many early-stage vocal cord cancers as patients do not have to undergo a seven-week-long course of radiation therapy with similar oncologic outcomes. The recovery time following laser surgery is usually only a few days with typically no voice or diet restrictions postoperatively. Cancer outcomes after laser surgery have also proven to be excellent when compared to other treatment modalities

5 years after KTP laser removal of the cancer the patient has no signs of recurrence. She has no complications and her voice is normal.
