Voice restoration after total laryngectomy using provox 2 (generation II) prosthesis

Area of Science:

• Otorhinolaryngology
• Speech Pathology
• Oncology

Background:

• Voice restoration is crucial after total laryngectomy, presenting a significant challenge.
• Prosthetic voice rehabilitation is currently the most effective method for voice restoration.
• Advanced laryngeal squamous cell carcinoma necessitates total laryngectomy.

Purpose of the Study:

• To evaluate the efficacy of tracheoesophageal puncture (TEP) and voice prosthesis insertion for voice restoration.
• To assess the outcomes of primary versus secondary voice prosthesis insertion.
• To examine the performance and tolerability of the Provox 2 voice prosthesis.

Main Methods:

• 12 patients with advanced laryngeal squamous cell carcinoma underwent total laryngectomy.
• Eight patients received primary voice prosthesis insertion; four had secondary TEP procedures.
• Speech quality and prosthesis-related complications were monitored.

Main Results:

• 80% of patients achieved good and understandable speech with the voice prosthesis.
• No significant difference in speech quality was observed between primary and secondary insertion groups.
• Complications included prosthesis replacement (salivary leakage, granulation) and mild mucositis/tracheitis post-radiotherapy.

Conclusions:

• TEP puncture and voice prosthesis insertion are safe and effective for post-laryngectomy voice restoration.
• The Provox 2 voice prosthesis is well-tolerated, effective, and features an improved design for easier changes.
• This method provides a valuable solution for patients seeking voice rehabilitation after laryngectomy.
