The etiology of postoperative pharyngocutaneous fistula (PCF) formation following major head and neck surgery is multifactorial and the incidence varies greatly. We reviewed retrospectively the records of 108 consecutive patients who underwent a total laryngectomy during the period from December 1992 to December 2002 at the Helsinki University Central Hospital, Helsinki, Finland. PCF occurred postoperatively in 19 (18%) patients. Two additional patients (2%) developed a PCF later than 30 days after laryngectomy. Nineteen percent of these patients with fistula formation had received previous radiation therapy and laryngectomy was performed for local recurrence. Eighteen (86%) of the all fistulae closed spontaneously and surgical closure of the fistula was performed in three (14%) cases. We conclude that the PCFs in our patient population occurred both in radiated and nonirradiated patients. Although most fistulae close spontaneously without surgical intervention this complication leads to prolonged hospitalization and increased patient morbidity.

We describe the speech rehabilitation outcome of patients treated with total laryngectomy or total laryngopharyngectomy and insertion of Provox voice prostheses (Atos Medical AB, Hörby, Sweden) at the Helsinki University Central Hospital. We performed a retrospective chart review of 95 patients (88 men and 7 women; mean age, 63.5 years) who underwent insertion of a voice prosthesis in the period 1992 to 2002. Eighty-one percent (77/95) of the patients underwent a primary prosthesis insertion at the time of laryngectomy. A head and neck surgeon, a laryngologist, and a speech therapist rated the long-term tracheoesophageal speech of 78% (74/95) of the patients as good or average. The main causes for replacement of the device were obstruction, leakage or inadequate size of the prosthesis, and granulation or leakage around the fistula. According to our 10-year experience, use of the Provox prosthesis is an effective method of postlaryngectomy voice rehabilitation, and it continues to be our preferred method of voice restoration in the majority of cases.
