How many types of TEP are there?
A tracheoesophageal prosthesis can be broadly classified into two types, patient inserted or non-indwelling type and a clinician inserted or indwelling type.
What is TEP speech?
Speech through voice production created by passage of air through a valve positioned in the party wall between the trachea and pharynx or upper esophagus (tracheoesophageal puncture [TEP] speech) is dependent on a prosthesis.
Can a voice box be replaced?
A voice prosthesis is the most common way to restore speech after surgery. After surgery to remove the whole of your voice box (total laryngectomy), you are no longer able to speak in the normal way. But there are different ways you can communicate and learn to speak again.

Blom-Singer voice prostheses are available as patient-maintained (ex: Duckbill, Low Pressure) or clinician-maintained (ex: Indwelling).
What is the difference between a non-indwelling and an indwelling voice prosthesis?
‘Non-indwelling’ voice prostheses can be replaced by the patients themselves, whereas ‘indwelling’ prostheses have to be replaced by a medical professional.
