Comparison between Primary and Secondary Tracheoesophageal Puncture Prosthesis: A Systematic Review.
INTRODUCTION
Since the introduction of tracheoesophageal puncture (TEP) and placement of voice prosthesis, this has become the method of choice to achieve speech rehabilitation after total laryngectomy.


OBJECTIVE
To compare the complications and success in speech rehabilitation of patients undergoing rehabilitation after primary and secondary TEP (TEP1 and TEP2) through a systematic review.


METHODS
The literature survey included research in MedLine, Scielo, Lilacs, Cochrane and Websco until June 2016.


RESULTS
The rate of leakage around the prosthesis was higher in TEP1 (22.5 vs. 6.9%, p = 0.03). There were higher rates of wound infection (9.1 vs. 3.9%) and tracheal stenosis (8.5 vs. 4.5%) in the TEP1 group compared to TEP2, however with no statistical significance. The evaluation of speech quality was not possible due to the heterogeneity of the studies.


CONCLUSION
There is a reduction in the risk of leakage around the prosthesis among TEP2 patients.
