A double-blind randomized clinical trial of inflammatory cytokine and pepsin levels in the saliva of patients with voice prostheses. Head Neck 2024. [PMID: 38864228 DOI: 10.1002/hed.27847] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2024] [Revised: 05/25/2024] [Accepted: 06/06/2024] [Indexed: 06/13/2024] Open
Abstract
BACKGROUND Tracheoesophageal speech is one of the most effective method used for voice rehabilitation after laryngectomy. The main limitation is the need for periodic voice prothesis (VP) replacements. The process of developing VP usage complications is still unexplored. The aim of this study was to assess the level of cytokines (IL-1β, IL-6, IL-8, IL-10, TNFα) and pepsin in saliva as potential factors reducing VP longevity. METHODS Prospective double-blind randomized clinical trial was conducted (NCT04268459). Patients were randomly divided into two groups depending on VP replacement regimen (regular-every 3 months, or irregular-when complications occur). Levels of IL-1β, IL-6, IL-8, IL-10, TNFα, and pepsin in saliva samples (fasting and after eating) of laryngectomized patients were measured using ELISA tests. RESULTS Fifty-two patients (26 in both groups) with control group (7 patients) participated in the study. The level of IL-1β, IL-6, IL-8, IL-10, TNFα, and pepsin did not differ according to regularity of VP replacements (p = 0.301-0.801). IL-6 levels were significantly higher when VP complications occurs (p = 0.012). CONCLUSIONS The saliva components were not significantly different depending on the frequency of VP replacements. IL-6 plays an important role in the development of VP use complications.

Prevention of periprosthetic leakage with double flange voice prosthesis: a systematic review and management protocol proposal. LOGOP PHONIATR VOCO 2023; 48:129-136. [PMID: 35213274 DOI: 10.1080/14015439.2022.2042595] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2020] [Revised: 02/02/2022] [Accepted: 02/09/2022] [Indexed: 10/19/2022]
Abstract
OBJECTIVE To conduct a systematic review of the use and results of the Provox®VegaTMXtraSealTM in the prevention of periprosthetic leakage and to propose a management protocol for this voice prosthesis. METHODS Systematic search based on the PRISMA Statement during February 2020. Keywords were double flange, periprosthetic leakage, voice prosthesis, and laryngectomy. RESULTS Four articles with 315 voice prosthesis (94 XtraSeal and 221 controls) in 55 patients were found. The XtraSeal mean duration was 114.28 ± 73.2 (CI 95%, 98.29-130.26) days compared to 102.98 ± 17.74 (CI 95%, 100.62-105.35) days of the control group. Out of 266 replacements, endoprosthetic leakage was the most frequent cause in both groups (62.41%). Periprosthetic leaks were less frequent in the XtraSeal (9.62%) than in the control group (22.43%). CONCLUSIONS The XtraSeal could be effective in preventing periprosthetic leakage and lengthening the time between replacements. Studies with a robust methodology are necessary to confirm these results. Managing voice prosthesis is complex and requires a multidisciplinary and systematic approach by experienced professionals to reduce replacements and complications. Incorrect placement of the XtraSeal could cause a foreign body reaction and consequently inflammation, extrusion, or pressure lesions. The Tower of Hercules protocol: (1) Measurement of the tracheoesophageal fistula using the Provox® Measure, (2) Minimization of XtraSeal slack by avoiding the complete visualization of the prosthesis' blue ring, (3) Nasofibroscopic examination of the oesophageal wall confirming both flanges are in correct position; could prevent or minimize complications derived from the use of the XtraSeal.

Cost-Effectiveness Study of Double-Flange Voice Prostheses in the Treatment of Periprosthetic Leakage in Laryngectomized Patients. J Pers Med 2023; 13:1064. [PMID: 37511677 PMCID: PMC10381411 DOI: 10.3390/jpm13071064] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2023] [Revised: 06/26/2023] [Accepted: 06/27/2023] [Indexed: 07/30/2023] Open
Abstract
BACKGROUND Tracheoesophageal speech with a voice prosthesis is considered the rehabilitation treatment of choice in laryngectomized patients. The main reasons for prosthesis failure are endoprosthetic leakage and periprosthetic leakage. The Provox XtraSeal® stent incorporates an additional double flange on the esophageal side to prevent periprosthetic leakage. The objective of this study is to compare the duration and costs of the Provox Vega® and Provox XtraSeal® prostheses used in these patients in a tertiary university hospital. MATERIALS AND METHODS A prospective crossover case study of laryngectomees with Provox Vega® who underwent Provox XtraSeal® placement due to recurrent periprosthetic leaks and decreased theoretical prosthesis life. The duration and possible factors affecting voice prostheses were studied using Kaplan-Meier curves and Cox regression. A cost-effectiveness analysis was carried out from the perspective of the Spanish National Health System with an incremental cost-effectiveness calculation. RESULTS A total of 38 patients were recruited, 35 men and 3 women, with a mean age of 66.26 ± 9.36 years old. Information was collected from 551 voice prostheses, 484 Provox Vega® and 68 Provox XtraSeal®. The mean duration of Provox Vega® was 119.75 ± 148.8 days and that of Provox XtraSeal® was 181.99 ± 166.07 days (p = 0.002). The most frequent reason for replacement was endoprosthetic leakage in both groups: 283 (60.86%) in the case of Provox Vega® and 29 (48.33%) in that of XtraSeal® (p < 0.000). To obtain no cost differences (ICE ~ 0) between Provox Vega and Provox XtraSeal, the latter should cost EUR 551.63. CONCLUSIONS The Provox XtraSeal® is a cost-effective option in patients with increased prosthesis replacements due to periprosthetic leakage, reducing the number of replacements, increasing the duration of the prosthesis, and providing savings compared to Provox Vega®.

Abstract
PURPOSE Tracheoesophageal speech is considered the gold standard for rehabilitation following total laryngectomy. The main reason of voice prosthesis failure is the endoprosthesis leakage. Provox ActiValve® incorporates a magnet-based valve system to achieve active closure of the valve to treat these leakages, with the drawback of being significantly more expensive. The aim of the study was to compare the Provox Vega® and Provox ActiValve® duration and costs in patients with replacements increase due to endoprosthetic leakage. METHODS Prospective case-crossover study in laryngectomized patients with Provox Vega® and endoprosthesis leakage to whom a Provox ActiValve® was placed. Survival and possible factors that affect voice prosthesis were studied using Kaplan-Meier curves and Cox Proportional Hazards Regression. Cost-effectiveness analysis from the perspective of the Spanish Public National Health System with incremental cost-effectiveness calculation was performed. RESULTS A total of 159 prostheses were evaluated. The most frequent reason for replacement was the endoprosthesis leakage (N = 129; 83.77%) in both models. The mean duration-time of Provox Vega® was 44.77 ± 2.82 days (CI 95%, 39.18-50.35; median 36 days), and 317.34 ± 116.8 days (CI 95% 86.66-548; median 286 days) for the Provox ActiValve® (p < 0.000). For every replacement not made thanks to the Provox ActiValve® there was saving of 133.97€ CONCLUSIONS: The Provox ActiValve® is a cost-effective solution in patients with increased prosthesis replacements due to endoprosthetic leakage, reducing the number of changes and cost compared to Provox Vega®.

Abstract
OBJECTIVE This study aimed to assess individual preference, symptoms and compliance between habitual use of Provox XtraFlow and the combination of Provox XtraFlow during the day and Provox Luna during the night for heat and moisture exchanger therapy in laryngectomised patients. METHOD This was an open, randomised, crossover trial for 25 days. After this first study period and a 5-day wash-out period, treatments were switched for another 25 days. RESULTS A total of 28 patients were enrolled. Differences were found (p = 0.009) in the incidence of dermatological problems with XtraFlow (46.4 per cent) versus Provox Luna (14.3 per cent), as well as in the need to abandon the use of adhesives (46.4 per cent vs 10.7 per cent; p = 0.003). A total of 60.7 per cent of the patients preferred the Provox Luna system as their preference for heat and moisture exchanger therapy. CONCLUSION The Provox Luna system is a viable additive to heat and moisture exchanger therapy, especially in the setting of compliance concerns and in patients who desire dermatological relief overnight.

Abstract
INTRODUCTION Tracheoesophageal speech is considered the gold standard for rehabilitation following total laryngectomy. One of the main problems of voice prosthesis is the periprosthesis leakage. Provox Vega XtraSeal incorporates a double flange on the pharyngeal side of the prosthesis in order to avoid these failures. The aim of the study is to compare the device lifetime between the Provox Vega and Provox Vega XtraSeal and to examine possible related factors that influence their duration. METHODS Prospective case-crossover study in 20 laryngectomised patients with Provox Vega and periprothesis leakage to whom a Provox Vega XtraSeal was placed. Survival and possible factors that affect voice prosthesis were studied using Kaplan-Meier curves and Cox Proportional Hazards Regression with Schoenfeld residuals to test the possible assumptions. RESULTS A total of 230 prostheses were evaluated. The most frequent reason for replacement was due to an endoprosthesis leakage (n = 146, 67%) in both models. Mean lifetime of Provox Vega was 104.474 ± 7.29 days (CI 95% 90.19-118.76) and of Provox XtraSeal was 176.76 ± 26.46 days (CI 95% 124.9-228.61) (P = .012). Complementary treatment with radiotherapy demonstrated a higher device survival (P = .007). DISCUSSION Provox XtraSeal seems to be effective reducing the number of changes due to periprosthetic leakage, thus increasing the survival of voice prosthesis.
