Prospective randomized comparative study of tracheoesophageal voice prosthesis: Blom-Singer versus Provox

Area of Science:

• Laryngology
• Speech-Language Pathology
• Prosthodontics

Background:

• Tracheoesophageal voice prostheses are crucial for voice restoration after laryngectomy.
• Blom-Singer and Provox devices are widely used but require comparative analysis.

Purpose of the Study:

• To compare the voice quality, prosthesis longevity, and patient satisfaction between Blom-Singer and Provox tracheoesophageal voice prostheses.
• To analyze objective and subjective voice parameters and identify factors influencing outcomes.

Main Methods:

• A prospective study involving 52 patients and 113 tracheoesophageal voice prostheses (Blom-Singer and Provox).
• Voice recordings were analyzed objectively and subjectively at 1 and 4 months post-placement.
• Patient satisfaction and prosthesis survival were assessed, with subgroup analyses for placement type and surgical extent.

Main Results:

• Both Blom-Singer and Provox prostheses demonstrated comparable voice quality, longevity, and patient satisfaction.
• Provox showed slightly better cleaning management, while Blom-Singer trended towards superior voice quality.
• Secondary placements and total laryngectomies yielded better voice outcomes.

Conclusions:

• Blom-Singer and Provox prostheses provide effective voice restoration with similar outcomes.
• Clinical decisions should consider patient-specific factors like cost, maintenance, and individual preference alongside performance.
• Further research may explore long-term functional differences and patient-reported quality of life.
