The laryngectomy surgery results in anatomical and physiological changes in the larynx and surrounding structures. Consequently, swallowing function can undergo changes as well, compromising the patient's oral feeding ability and nutrition. [30] Patients may experience distress, frustration, and reluctance to eat out due to swallowing ...
Indications include voice rehabilitation for patients who are undergoing a total laryngectomy (primary puncture) or patients who have had a total laryngectomy in the past (secondary puncture). Contra-indications are mainly related to the use of the voice prosthesis and not the puncture procedure itself. It is important to have healthy tissue at ...
Another option for restoring speech after a laryngectomy is the tracheoesophageal puncture or TEP. In this simple surgical procedure, a small puncture is made between the trachea and the esophagus, and a one-way air valve is inserted. This air supply can be used to cause vibrations of the pharyngoesophageal sphincter in a similar manner to ...
An individual combination of voice prosthesis, heat and moisture exchanger after laryngectomy and attachment is important for good speech and pulmonary rehabilitation. [25] The HME sometimes is combined with free-hands-switch and virus and bacteria filter. [26]
Alaryngeal speech is speech using an airstream mechanism that uses features other than the glottis to create voicing.There are three types: esophageal, buccal, and pharyngeal speech.
Along with developing esophageal voice, using a speech synthesizer, or undergoing a surgical procedure, the electrolarynx serves as a mode of speech recovery for laryngectomy patients. [ 2 ] [ 3 ] The Voice Quality Symbol for electrolaryngeal phonation in speech is И, approximating the symbol for electricity.
after a laryngectomy, the esophagus may be used (notated {Œ} for simple esophageal speech, {Ю} for tracheo-esophageal speech in VoQS, and notated {И} for electrolaryngeal speech). See esophageal speech. [2]
At that point, the laryngopharynx is continuous with the esophagus posteriorly. The esophagus conducts food and fluids to the stomach; air enters the larynx anteriorly. During swallowing, food has the "right of way", and air passage temporarily stops.
