Fungal colonization of tracheoesophageal voice prosthesis

Laryngectomized patients fitted with tracheoesophageal (TE) puncture voice prosthesis may experience frequent failures in adequate production of neophonation. In some cases, these phonatory problems result from obstruction of the voice prosthesis with various deposits. The nature of these deposits was studied with mycologic techniques and by light and scanning electron microscopy. Candida albicans and other fungal species were identified.
