Voice rehabilitation with voice prosthesis: Long term results, complications and risk factors

Objectives: Despite the advances in surgical and non-surgical organ preservation treatments, total laryngectomy (TL) remains the most effective treatment in advanced larynx cancer and as salvage procedure in chemoradiation failure. One of the most devastating sequel after TL is loss of voice. Voice prosthesis (VP) is currently the preferred choice for voice rehabilitation. The purpose of this study is to identify VP complications, its lifespan and factors that influence the longevity of the VP.

Methods: We performed a retrospective study at a Tertiary University Hospital. Medical records of patients that underwent total laryngectomy, between January 1st of 2008 and 31st of December of 2017 were analyzed.

Results: Of the 84 patients that underwent laryngectomy, 60 had VP. The average age at the time of surgery 60.2 years old and there was a male preponderance (57:3). The mean lifespan of the prosthesis was 7.53 months. Leakage through the prosthesis was the most common reason for replacement of the prosthesis, followed by leakage around the prosthesis. Follow up time and manual suture were associated with prosthesis replacement. There was no significant relationship between the staging, tumor location or adjuvant radiotherapy and number of prosthesis replacement or its lifespan.

Conclusions: Rehabilitation after TL is of major importance to improve quality of life after surgery. Tracheoesophageal puncture with voice prosthesis is a safe procedure for vocal rehabilitation and was performed in the majority of patients in our study. Follow-up time and type of suture were the main determinants of the lifespan of the prosthesis.
