Abstract
OBJECTIVE This study aimed to report on the UK rate of surgical voice restoration usage and investigate the factors that influence its uptake. METHOD A national multicentre audit of people with total laryngectomy was completed over a six-month period (March to September 2020) in response to the coronavirus disease 2019 pandemic. This study is a secondary analysis of the data collected, focusing on the primary communication methods used by people with total laryngectomy. RESULTS Data on surgical voice restoration were available for 1196 people with total laryngectomy; a total of 852 people with total laryngectomy (71 per cent) used surgical voice restoration. Another type of communication method was used by 344 people. The factors associated with surgical voice restoration in the multiple regression analysis were sex (p = 0.003), employment (employed vs not employed, p < 0.001) and time post-laryngectomy (p < 0.001). CONCLUSION This study provides an important benchmark for the current status of surgical voice restoration usage across the UK. It found that 71 per cent of people with total laryngectomy used surgical voice restoration as their primary communication method.

Abstract
PURPOSE The use of tracheoesophageal prostheses has become the gold standard in vocal rehabilitation of patients undergoing total laryngectomy. However, this method also has limitations, such as the need for frequent replacement of prostheses due to leakage or other complications. We have designed a study to access the clinical profile of patients using tracheoesophageal prostheses as vocal rehabilitation after total laryngectomy and to determine the average rate of changes, as well as the main causes of prostheses replacement. METHODS A retrospective cohort study was performed based on patients who underwent rehabilitation with voice prostheses after total laryngectomy between 2008 and 2017. RESULTS The sample consisted of 93 patients and 432 vocal prostheses replacement events. The median change of prostheses per patient was 210.25 days, (range 57.33 to 651.50). The most frequent cause of prostheses replacement was leakage through the prostheses, 218 (50.46%). Lower level of education was associated to higher prostheses replacement rate. CONCLUSION The results of this study show that the median of prostheses durability is higher than that presented in the literature, the main cause of replacement was protheses leakage and that low educational level is associated to higher replacement rate.

Abstract
PURPOSE Surgical voice restoration (SVR) is associated with improved patient quality of life following laryngectomy. This study aims to determine the impact of the COVID-19 pandemic on patients with SVR and analyse the complications in this cohort of patients. METHOD A retrospective review of all patients with SVR at a single tertiary ear, nose, and throat (ENT) unit in the UK for 12 months during the COVID-19 pandemic, with comparison to the preceding 12 months. A survey was also administered to assess patients' experiences during the pandemic. RESULT Thirty-six patients were included in this study. During the pandemic period, 19.5% (n = 7) patients had significant complications, with five patients needing surgery to restore speech. In the 12 months pre-pandemic, 13.5% (n = 5) had significant complications, although none required surgery to restore speech. Six patients (19.4%) felt these complications were avoidable in normal circumstances. Further, 30.5% (n = 11) of patients reported a delay in seeking medical attention due to concerns about their vulnerability to COVID-19. CONCLUSION The COVID-19 pandemic has had an impact on many patients with SVR. This has resulted in a large proportion of patients experiencing delayed care, a loss of voice, a need for further surgical intervention, and negative impacts on their quality of life.

Abstract
BACKGROUND The Provox Vega High Performance (PVHP) is a newly developed voice prosthesis (VP) with an aim to achieve a longer and more predictable lifetime. OBJECTIVES This feasibility study aims to assess patient acceptance of the PVHP VP, evaluate adverse events, voice quality, and device lifetime. METHODS Laryngectomized patients previously using a Provox Vega or ActiValve Light were included. Acceptance and voice outcomes were evaluated at two-time points with a 2-week interval. Baseline measurements were taken with the standard VP, followed by placement of the PVHP for the 2-week assessment. RESULTS Fifteen participants completed the study, with thirteen being initial Vega-users. PVHP acceptance was 87% 2 weeks after placement. Median device lifetime for all VPs was 64 d (range 14-370). In the subgroup without periprosthetic leakage, the median device lifetime was 101 d (range 31-370). Acceptance dropped to 40% after device failure. Voice quality did not differ between PVHP and baseline VP. The most reported adverse event was PVHP valve stickiness (46%). CONCLUSION AND SIGNIFICANCE Acceptance of the PVHP is largely dependent on device lifetime, decreasing from 87% to 40% after leakage or replacement. Voice quality remains consistent across different VPs. Developing a long-lasting VP remains a challenge.

Abstract
The implantation of a voice prosthesis has become a standard procedure during a laryngectomy. A voice prostheses enables patients to develop speech shortly after surgery, which strongly improves rehabilitation and quality of life.The lifetime of a voice prosthesis is limited and highly variable due to different causes. A replacement is usually necessary several times a year and can easily been done in an outpatient setting with surface anesthesia. In some cases, replacing the prosthesis becomes difficult. This article will take a closer look at different reasons that can lead to difficulties in prostheses replacement and discuss possible solutions, thereby focusing especially on a retrograde technique. The aim of this article is to help colleagues that already have experience with voice prostheses and want to expand their therapeutic armamentarium.

Abstract
OBJECTIVE Voice prosthesis leakage significantly affects the quality of life of patients undergoing laryngectomy, causing insecurity and frequent unplanned hospital visits and costs. In this study, the concept of prophylactic voice prosthesis replacement was explored to prevent leakages. STUDY DESIGN Retrospective cohort study. SETTING Tertiary hospital. METHODS This study included all patients who underwent laryngectomy between 2000 and 2012 in the Netherlands Cancer Institute. Device lifetimes and voice prosthesis replacements of a retrospective cohort were used to calculate the number of needed voice prostheses per patient per year to prevent 70% of the leakages by prophylactic replacement. Various strategies for the timing of prophylactic replacement were considered: adaptive strategies based on the individual patient's history of replacement and fixed strategies based on the results of patients with similar voice prosthesis or treatment characteristics. RESULTS Patients used a median 3.4 voice prostheses per year (range, 0.1-48.1). We found high inter- and intrapatient variability in device lifetime. When prophylactic replacement is applied, this would become a median 9.4 voice prostheses per year, which means replacement every 38 days, implying >6 additional voice prostheses per patient per year. The individual adaptive model showed that preventing 70% of the leakages was impossible for most patients and only a median 25% can be prevented. Monte-Carlo simulations showed that prophylactic replacement is not feasible due to the high coefficient of variation (SD/mean) in device lifetime. CONCLUSION Based on our simulations, prophylactic replacement of voice prostheses is not feasible due to high inter- and intrapatient variation in device lifetime.

Abstract
PURPOSE The study aimed to evaluate the impact of different variables on the longevity of Voice Prosthesis (VP) in patients after total laryngectomy. PATIENTS AND METHODS This retrospective cohort study is based on data about a continuous series of 328 third-generation VP, which were implanted between 2016 and 2020. Data about the VP users' age, sex, place of residence, laryngeal tumor stage, neck irradiation, VP size, and the use of Heat and Moisture Exchanger (HME) were obtained and analyzed. The effect of these variables on VP lifetime was determined. RESULTS The median lifetime of VPs in patients 65 years old and above was 182 days (95% CI 168-196), versus 146 days (95% CI 130-162) (P = 0.033) in patients younger than 65. Neck irradiation was associated with a longer VP median lifetime of 161 days (95% CI 142-180) compared to 126 days (95% CI 100-152) with no prior neck irradiation (P = 0.046). HME usage was associated with significantly increased longevity of VPs: 182 days (95% CI 156-208) with HME and 149 days (95% CI 132-166) without HME usage (P = 0.039). CONCLUSION The results of the present study suggest that neck irradiation, and routine use of use of HME are positively associated with the longevity of VPs.

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
This study aimed to investigate the potential application of ceragenins (CSAs) as new candidacidal agents to prevent biofilm formation on voice prostheses (VPs). The deterioration of the silicone material of VPs is caused by biofilm growth on the device which leads to frequent replacement procedures and sometimes serious complications. A significant proportion of these failures is caused by Candida species. We found that CSAs have significant candidacidal activities in vitro (MIC; MFC; MBIC), and they effectively eradicate species of yeast responsible for VP failure. Additionally, in our in vitro experimental setting, when different Candida species were subjected to CSA-13 and CSA-131 during 25 passages, no tested Candida strain showed the significant development of resistance. Using liquid chromatography–mass spectrometry (LC-MS), we found that VP immersion in an ethanol solution containing CSA-131 results in silicon impregnation with CSA-131 molecules, and in vitro testing revealed that fungal biofilm formation on such VP surfaces was inhibited by embedded ceragenins. Future in vivo studies will validate the use of ceragenin-coated VP for improvement in the life quality and safety of patients after a total laryngectomy.

Abstract
Fungal biofilm formation on voice prosthesis (VP) is a major health problem that requires repeated replacement of the prosthesis. Candida albicans is one of the pathogens that frequently inhabits the VP. We proposed that coating VPs with sustained-release varnish (SRV) containing clotrimazole (CTZ) might prevent fungal biofilm formation. The long-term antifungal activities of SRV-CTZ- versus SRV-placebo-coated VPs was tested daily by measuring the inhibition zone of C. albicans seeded on agar plates or by measuring the fungal viability of C. albicans in suspension. The extent of biofilm formation on coated VPs was analyzed by confocal microscopy and scanning electron microscopy. We observed that SRV-CTZ-coated VPs formed a significant bacterial inhibition zone around the VPs and prevented the growth of C. albicans in suspension during the entire testing period of 60 days. Fungal biofilms were formed on placebo-coated VPs, while no significant biofilms were observed on SRV-CTZ-coated VPs. HPLC analysis shows that CTZ is continuously released during the whole test period of 60 days at a concentration above the minimal fungistatic concentration. In conclusion, coating VPs with an SRV-CTZ film is a potential effective method for prevention of fungal infections and biofilm formation on VPs.

Abstract
Purpose Our aim was to assess the different voice prostheses (VPs) to identify the most efficient, safest, patient-tailored, longest lifetime, and inexpensive VPs and assess the different factors affecting their quality. Method In September 2017, 15 databases were searched to include all randomized controlled trials. A new search was done in May 2019 to include all other study design articles, which include all the new-era VPs subtypes. Network meta-analysis (NMA) was applied to all 27 outcomes, besides NMA overall and partial order setting was done by using Hasse scatter plots. p values were used in NMA, where the best VPs are approaching one and the least approaches zero. Meta-analysis was done for the rest of the outcomes. Results Two hundred one articles were eligible for inclusion in our study (N = 11,918). Provox-2 was significantly the most efficient and safest device concerning the most patient preference (odds ratio [OR] = 33.88 [0.65, 1762.24]; p = .92), the least dislodgement (risk ratio [RR] = 0.27 [0.13, 0.57]; p = .79), the least airflow resistance (RR = 0.42 [0.08, 2.11]; p = .84), the least granulation formation (RR = 0.73 [0.02, 26.32]; p = .60), and the least VPs' inaccurate size (RR = 0.77 (0.23, 2.61); p = .66). Heat and moisture exchanger addition showed a significant increase in maximum phonation time and breathing experience, with p values (1 and .59), respectively. While heat and moisture exchanger addition showed a significant decline in stoma cleaning frequency, coughing frequency, forced expectoration, sputum production, sleeping problems, and loosening of adhesive, with p values (.99, .72, .69, .96, 1, and 0.96), respectively, Groningen low resistance and Nijdam were considered the worst devices with both overall mean p value of .44. Conclusions Provox-2 is considered the best choice as being the most preferable for patients, with the least airflow resistance, dislodgment, granulation formation, and prosthesis inaccurate size. Groningen low resistance and Nijdam were considered the worst devices according to our analysis. Supplemental Material https://doi.org/10.23641/asha.14802903.

Abstract
OBJECTIVE Periprosthetic leakage represents the most demanding long-term complication in the voice prosthesis rehabilitation. The aim of this article is to discuss the various causes of periprosthetic leakage and to propose a systematic management algorithm. STUDY DESIGN Retrospective cohort study. SETTING Otolaryngology clinic of the University Polyclinic A. Gemelli-IRCCS Foundation. METHODS The study included 115 patients with voice prosthesis who were treated from December 2014 to December 2019. All patients who experienced periprosthetic leakage were treated with the same step-by-step therapeutic approach until it was successful. Incidence, management, and success rate of every attempt are analyzed and discussed. RESULTS Periprosthetic leakage was reported 330 times by 82 patients in 1374 clinic accesses. Radiotherapy, timing of tracheoesophageal puncture, and type of total laryngectomy (primary or salvage) did not influence the incidence of periprosthetic leakage. Salvage total laryngectomy increases the risk of more clinically relevant leakages. CONCLUSION By using a systematic algorithm with a step-by-step standardized approach, periprosthetic leakage management could become a less treacherous issue.

Abstract
Voice prosthesis implantation with the creation of a tracheoesophageal fistula is the gold standard procedure for voice rehabilitation in patients after a total laryngectomy. All patients implanted with a voice prosthesis (VP) have biofilms of fungi and bacteria grow on their surface. Biofilm colonization is one of the main reasons for VP degradation that can lead to VP dysfunction, which increases the high risk of pneumonia. In a 20-month evaluation period, 129 cases of prostheses after replacement procedures were investigated. Microbiological examination of the biofilms revealed that there were four of the most common fungi species (Candida spp.) and a large variety of bacterial species present. We studied the relationship between the time of proper function of Provox VP, the microorganism composition of the biofilm present on it, and the degradation level of the silicone material. Evaluation of the surface of the removed VP using an atomic force microscope (AFM) has demonstrated that biofilm growth might drastically change the silicone's mechanical properties. Changes in silicone stiffness and thermal properties might contribute to the failure of VP function. Our data can serve in future studies for the development of methods to prevent or inhibit biofilm formation on the VP surface that would translate to an increase in their durability and safety.

Abstract
Objective To describe a remote approach used with patients with voice prosthesis after
laryngectomy during the COVID-19 pandemic and the resulting clinical
outcomes in terms of voice prosthesis complications management, oncological
monitoring, and psychophysical well-being. Study Design Prospective cohort study. Setting Otolaryngology Clinic of the University Polyclinic A. Gemelli, IRCCS
Foundation. Subjects and Methods All patients with voice prosthesis who underwent laryngectomy followed by our
institute were offered enrollment. Patients who agreed to participate were
interviewed to inquire about the nature of the need and to plan a video call
with the appropriate clinician. Before and 1 week after the clinician’s
call, patients were tested with the Hospital Anxiety and Depression Scale.
Degrees of satisfaction were investigated with a visual analog scale. A
comparison between those who accepted and refused telematic support was
carried out to identify factors that influence patient interest in
teleservice. Results Video call service allowed us to reach 37 (50.68%) of 73 patients. In 23
(62.16%) of 37 cases, the video call was sufficient to manage the problem.
In the remaining 14 cases (37.83%), an outpatient visit was necessary.
Participants who refused telematic support had a significantly shorter time
interval from the last ear, nose, and throat visit than patients who
accepted (57.95 vs 96.14 days, P = .03). Video-called
patients showed significantly decreased levels of anxiety and depression
(mean Hospital Anxiety and Depression Scale total score pre– vs post–video
call: 13.97 vs. 10.23, P < .0001) and reported high
levels of satisfaction about the service. Conclusion Remote approach may be a viable support in the management of patients with
voice prosthesis rehabilitation.

Abstract
Indwelling silicone valves called voice prostheses (VPs) are the gold standard for speech rehabilitation in patients with laryngeal cancer following total laryngectomy. Reported VP lifespans amongst these patients are highly variable but when devices fail patients experience loss of voice and an increase risk of chest infection. Early failure of VP is a current clinical concern that is associated with regular hospital visits, reduced quality of life and associated medical cost. Poly-microbial biofilms comprised of both bacterial and fungal microorganisms readily colonize VPs and are linked to loss of device performance and its early failure in addition to providing a reservoir for potential infection. Our detailed analysis of poly-microbial biofilm composition on 159 early failing VPs from 48 total laryngectomy patients confirmed Candida albicans as the predominant fungal species and Staphylococcus aureus as the most common bacterial colonizer within our patient cohort. Using a combination of microbiological analysis, patient data and a high-throughput antifungal test assay mimicking in vivo conditions we established an evidence based precision antifungal treatment approach to VP management. Our approach has allowed us to implement a personalized VP management pathway, which increases device in situ lifespan by an average of 270%. Our study represents a significant step forward in both our understanding of the cause of VP failure and a new effective treatment pathway that offers tangible benefit to patients.

Abstract
Background With the increasing necessity for total laryngectomy (TL) after prior (chemo)radiotherapy, prosthetic vocal rehabilitation outcomes might have changed. Methods Retrospective cohort study including all patients laryngectomized between 2000 and 2012 with a voice prosthesis (VP) in the Netherlands Cancer Institute. Results Median device lifetimes of the standard Provox2 and Vega VPs are 63 and 66 days, respectively, and for the problem‐solving ActiValve Light and Strong VPs 143 and 186 days, respectively. In multivariable analysis, salvage TL and TL for a dysfunctional larynx (compared to primary TL) were associated with a shorter device lifetime. Almost half of the patients (48%) experienced tracheoesophageal puncture tract‐related problems, and this concerned 12% of all VP replacements. Conclusions Compared to historical cohorts, device lifetimes of regular Provox2 and Vega voice prostheses have decreased. Complications are not occurring more frequently but affect more patients. Nevertheless, the clinical reliability and validity of prosthetic voice rehabilitation is still sound.

Abstract
Voice prostheses have been examined for their effect on voice production but there is little datum on their effect on swallow function. This study investigated the difference between six commonly available voice prostheses in terms of swallowing. Laryngectomy patients had up to six voice prostheses placed in a random order over two visits. Swallowing was evaluated for each prosthesis using FEES (Fibreoptic Endoscopic Evaluation of Swallowing). After each prosthesis trial, patients self-evaluated their experience of swallowing. Three independent experts indicated which prosthesis they considered best for swallowing for each patient and judged residue on the voice prosthesis and in the upper esophagus. Raters were blinded to participant details, voice prosthesis type and scores of other raters. On patient self-evaluation, scores were equally distributed across all prostheses for swallowing. Experts most frequently chose the Blom Singer Low pressure and Blom Singer Classic Indwelling voice prostheses as best for swallowing but consensus was poor for most patients. Experts found that the Blom Singer Classic Indwelling and the Provox Vega had least residue on the voice prosthesis on thin liquid (p ≤ 0.001) and soft (p = 0.001), respectively. Experts also found that the Blom Singer Low Pressure had least residue in the upper esophagus on soft consistency (p ≤ 0.001). While self-evaluation by patients did not identify a consistently preferred prosthesis for swallow, many patients expressed personal preferences, suggesting benefits to involving patients in the choice of prosthesis. Some voice prostheses may be associated with lower levels of residue on the prosthesis and upper esophagus with certain consistencies.

Abstract
INTRODUCTION Tracheoesophageal speech is considered the gold standard for rehabilitation following total laryngectomy. Current literature is limited and contradictory about the possible causes of device failure. The aim of the study is to compare the device life-time between the Provox 2 and Provox Vega and to examine possible related factors that influence their duration. METHODS Retrospective case-crossover study in 34 laryngectomized patients who had undergone tracheoesophageal voice rehabilitation using indwelling Provox 2 and Provox Vega voice prostheses between 2010 and 2016 in a tertiary care centre. RESULTS A total of 440 prostheses were evaluated. The most frequent reason for replacement was due to an endoprosthesis leakage (n = 221, 64.2%) in both models. Radiotherapy increases the risk of prosthesis replacement (IRR = 1.88, p = 0.007) as well as bilateral neck dissection (IRR = 1.56, p = 0.017) in Provox 2. Age and unilateral neck dissection do not seem to influence the duration of the prosthesis. Mean life-time of Provox 2 was 106.64 days and 124.19 days for Provox Vega (p = 0.261). Complementary treatment with radiotherapy demonstrated a lower device survival (p < 0.001). DISCUSSION Results confirmed the non-significant differences on device life between Provox Vega and Provox 2, as well as the relevant role of radiotherapy treatment in the increase of replacements and diminution of the device duration.

[PMID: 29563733 PMCID: PMC5856693 DOI: 10.1007/s13193-017-0700-z] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2016] [Accepted: 08/28/2017] [Indexed: 10/18/2022] Open
Abstract
Tracheoesophageal voice puncture (TEP) coupled with the use of voice prosthesis has been considered as the gold standard for speech rehabilitation in patients of advanced laryngeal/hypopharyngeal carcinomas, who have undergone a total laryngectomy with or without partial pharyngectomy. Although prosthetic voice rehabilitation is commonly practiced worldwide including India, there is a paucity of published Indian data, more so in the current era of organ conservation. This study included 60 laryngectomized patients with a prosthetic voice rehabilitation at a tertiary cancer center in South India between January 1, 2010 and December 31, 2013. Among the 60 patients, the primary site of cancer was the larynx in 43 patients and hypopharynx in the remaining 17. All patients had undergone a primary TEP insertion, 55 in the upfront setting and five in the salvage (post-radiation/chemo-radiation) setting. The ability to retain a successful trachea-esophageal speech on follow-up (median 15.5 months) in our series was around 82%. The mean device life of voice prosthesis in our patient cohort was 16 months. There was surprisingly no significant difference in the prosthesis device life on correlation with age, co-morbidities, habitat, literacy status, pre-operative tracheostomy, setting of surgery, and the extent of surgery. Our series has successfully demonstrated the safety and feasibility of using primary TEP coupled with the use of voice prosthesis for voice rehabilitation in properly selected and motivated patients of advanced laryngeal and hypopharyngeal carcinomas across all clinical settings. A mean device life of 16 months makes prosthetic voice rehabilitation, an attractive as well as a financially viable option for patients in a resource constrained setting.

Abstract
OBJECTIVES/HYPOTHESIS This study compares the overall durability, phonation effort, and speech quality achieved by the Blom-Singer Dual Valve prosthesis to the same characteristics achieved by the single-valve prosthesis used in a select population of total laryngectomy patients who have demonstrated single-valve prosthesis failure within 3 months of placement. STUDY DESIGN Prospective phase IV study. METHODS Fourteen patients who had previously experienced early valve failure using a single-valve prosthesis had a Dual Valve placed by a speech language pathologist. A total of seventeen Dual Valves were inserted during routine clinical visits for valve replacement. Time intervals from insertion to replacement of the Dual Valve, as well as the average lifespan of patients' three previous single valves were collected. Subjective, categorical responses to speech quality and phonation effort for the Dual Valve compared to the single valve were collected on a questionnaire upon failure of the device. RESULTS The mean duration of the single valve was 60 days, with a median of 51 days, whereas the mean duration of the Dual Valve was 164 days, with a median duration of 84 days. Both sets of data were statistically significant, with a P value of .0131. Valve life was increased in 86% of patients, with 43% experiencing greater than 150 days improvement in valve duration when using the Dual Valve. Phonation effort was increased in 14% of patients, and speech quality was not significantly affected in any patients. CONCLUSIONS In this select population, the Dual Valve offers improved durability over the single valve without sacrificing speech quality, making it a preferred prosthesis option for patients experiencing single-valve failure in less than 3 months.

Abstract
Importance Voice prosthesis (VP) device life is a limiting factor of tracheoesophageal (TE) voice restoration that drives patient satisfaction, health care costs, and overall burden. Historic data suggest that TE VPs have an average device life of generally 3 to 6 months, but these data are typically derived from small samples using only 1 or 2 devices. Objective To reexamine current device life in a large, contemporary cancer hospital in the United States that uses a wide assortment of VPs. Design, Setting, and Participants This retrospective observational study included 390 laryngectomized patients with a tracheoesophageal puncture (TEP) who had VP management at MD Anderson Cancer Center between July 1, 2003, and December 31, 2013. Main Outcomes and Measures Tracheoesophageal voice-related outcomes were: (1) device life duration to VP removal, and (2) treatment-related and prosthetic-related factors influencing device failure. Primary independent variables included treatment history (extent of surgery and radiation history), VP type (indwelling vs nonindwelling, size, specialty features), and reason for removal (leakage, complication, other). Duration was examined using Kaplan-Meier analysis. Disease, treatment, and patient-specific factors were analyzed as predictors of duration. Results Overall, 3648 VPs were placed in the 390 patients (median [range] age, 62 [34-92] years). Indwelling prostheses accounted for more than half (56%) of the devices placed (55%, 20-Fr diameter; 33%, 8-mm length). More than two-thirds (69%) of prostheses were removed because of leakage, while the rest were removed for other reasons. Median device life was 61 days for all prostheses. Indwelling and nonindwelling VPs had median device lives of 70 and 38 days, respectively. There was no significant difference between specialty prostheses compared with standard devices (median duration, 61 vs 70 days, respectively). The Provox ActiValve (Atos Medical) had the longest life. Neither radiation therapy nor extent of surgery had a meaningful impact on device life. Conclusions and Relevance Our data suggest that VP duration demonstrates a lower durability than historically reported. This may reflect the intensification of treatment regimens that complicate TEP management in an era of organ preservation; however, further investigation is needed.

Abstract
The tracheoesophageal puncture (TEP) restores verbal communication after total laryngectomy using a one-way valved voice prosthesis (VP). Microbial colonization can shorten VP device life. Our aims were to investigate patterns of prosthetic and oral colonization, and record changes in VP device life after targeted decontamination. We conducted a retrospective review of TEP clinic patients who underwent microbial analysis of the VP between 01/2003 and 07/2013. Two subgroups were analyzed: (1) patients with microbial analysis of the VP and the mouth were analyzed to identify patterns of common contamination, and (2) patients who were prescribed targeted oral decontamination on the basis of the microbial analysis of the VP were analyzed to evaluate effects on device life. Among 42 patients, 3 patients had only fungal, 5 only bacterial, and 33 had polyspecies fungal and bacterial colonization. In the TEP-oral microflora subgroup (n = 15), 7 had common microorganisms in the mouth and on the VP. Among the decontamination subgroup (n = 23), 6 patients received broad spectrum rinse, 16 antifungal agents and 13 antibiotics, or a combination thereof. After targeted decontamination, the median device life of prostheses improved from 7.89 to 10.82 weeks (p = 0.260). The majority of patients with a suboptimal VP device life in this pilot had polyspecies bacterial and fungal colonization. VPs rarely had fungal contamination alone (3 %), and non-albicans fungal species were more common than expected. For these reasons, we are exploring the use of targeted decontamination regimens that were associated with 1.4-fold improvement in VP duration.

Abstract
Background: Tracheoesophageal voice prostheses are invaluable for speech rehabilitation in patients who have received total laryngectomy, but device failure impedes communication and creates psychosocial and financial burdens. This study compares the Provox 2 and Provox Vega voice prostheses on the parameter of device life. Methods: This was a retrospective observational study of 21 patients with 181 device replacements at an academic tertiary care medical center. Disparity in device life and factors that may influence device life were analyzed. Results: The mean device life for Provox 2, at 115.6 days (SE = 5.8), was longer than for Provox Vega, at 65.1 days (SE = 7.5) ( P < .001). Conclusions: Device longevity was greater for Provox 2 over Provox Vega. These results will facilitate the design of prospective studies to assess reasons for variations in device life between patients and device types.
