What is functional laryngectomy?

Laryngectomy is the removal of the larynx and separation of the airway from the mouth, nose and esophagus. In a total laryngectomy, the entire larynx is removed (including the vocal folds, hyoid bone, epiglottis, thyroid and cricoid cartilage and a few tracheal cartilage rings).

What is removed in a supraglottic laryngectomy?

Supraglottic laryngectomy or horizontal partial laryngectomy is an operation to remove the epiglottis, false vocal cords, and superior half of the thyroid cartilage.

What is supraglottic squamous cell carcinoma?

Early stage supraglottic squamous cell carcinoma (SSCC) is defined as T1 (tumor limited to one subsite of supraglottis with normal vocal cord mobility) or T2 (tumor invading more than one adjacent subsite of supraglottis or glottis or region outside of supraglottis), with no regional nodal spread [1].

What is supraglottic mass?

They are usually solitary, slow-growing,1,3 encapsulated tumors that grow eccentrically away from the nerve trunk. The internal branch of the superior laryngeal nerve is presumed to be the origin of a supraglottic schwannoma.

How long can you live with a total laryngectomy?

Median overall survival for total laryngectomy patients was 61 months versus 39 months for patients receiving chemoradiation. The survival of patients with stage T4a larynx cancer who are untreated is typically less than one year.

Can a laryngectomy be reversed?

Speech restoration after total laryngectomy has been revolutionized by the technique of tracheoesophageal puncture (TEP) and speech valve prosthesis placement. Unfortunately, complications may arise from this procedure, sometimes necessitating reversal and surgical closure of the TEP.

How painful is a laryngectomy?

Laryngectomy is a lengthy procedure that typically lasts between five and twelve hours. The surgery is performed under general anesthesia. That means you’ll be asleep and won’t feel pain during the procedure.

What is the function of glottis?

The glottis, a slit-like opening on the floor of the pharynx, is a valve that controls airflow in and out of the respiratory passages. The glottis opens directly into a boxlike larynx.

Where does a supraglottic laryngectomy take place?

During a supraglottic laryngectomy (sooprah-GLOT-tik lair-un-JECT-uh-me), a surgeon removes the top part of your voice box (larynx), near your vocal cords. Your doctor may ask you to have tests done before surgery.

What are the symptoms of supraglottic cancer in the throat?

Patients with supraglottic cancer often present with dysphagia; other common symptoms include airway obstruction, otalgia, development of a neck mass, or a “hot potato” voice. Patients with these symptoms should be referred for direct laryngoscopy without delay.

Which is more common laryngeal cancer or glottic cancer?

Lymph node metastasis are more common in supraglottic and subglottic tumors than with glottic cancers due to the minimal lymphatic drainage of the glottis. Distant metastases occur most frequently in the lungs and liver. Common sites of origin are the true vocal cords (glottis) and the supraglottic larynx.

How is Glottic Carcinoma of the voice treated?

Early-stage glottic carcinoma is treated with laser excision, radiation therapy, or occasionally open laryngeal surgery. Endoscopic laser resection and radiation therapy usually preserve a normal voice and post-treatment function and have similar cure rates.
