Practice of laryngectomy rehabilitation interventions: a perspective from Europe/the Netherlands

A double-blind randomized clinical trial of inflammatory cytokine and pepsin levels in the saliva of patients with voice prostheses

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.

Improving Hands-Free Speech Rehabilitation in Laryngectomized Patients with a Moldable Adhesive

OBJECTIVE

This study aims to assess the product performance of a new moldable peristomal adhesive with corresponding heating pad designed to facilitate and improve automatic speaking valve (ASV) fixation for hands-free speech in laryngectomized patients.

METHODS

Twenty laryngectomized patients, all regular adhesive users with prior ASV experience, were included. Study-specific questionnaires were used for data collection at baseline and after two weeks of moldable adhesive use. The primary outcome parameters were adhesive lifetime during hands-free speech, use and duration of hands-free speech, and patient preference. Additional outcome parameters were satisfaction, comfort, fit, and usability.

RESULTS

The moldable adhesive enabled ASV fixation adequate for hands-free speech in the majority of participants. Overall, the moldable adhesive significantly increased adhesive lifetime and duration of hands-free speech compared to participants' baseline adhesives (p < 0.05), regardless of stoma depth, skin irritation, or regular use of hands-free speech at baseline. The participants who preferred the moldable adhesive (55% of participants) experienced a significant increase in the adhesive lifetime (median of 24 h, range 8-144 h) and improved comfort, fit, and ease of speech.

CONCLUSION

The moldable adhesive's lifetime and functional aspects, including the ease of use and custom fit, are encouraging outcomes and enable more laryngectomized patients to use hands-free speech more regularly.

Understanding and predicting the performance of passive heat and moisture exchangers using a numerical model

BACKGROUND

To improve the understanding of the thermodynamics and performance of small passive hygroscopic Heat and Moisture Exchangers (HMEs), a computer model simulating HME function is required.

METHODS

We developed a numerical HME model to calculate the HME's water and heat exchange. The model was tuned and verified with experimental data and validated by applying it to HME design variations.

RESULTS

Verification of the model's results to the experimental data shows that the tuned model yields reliable results. The mass of the core, which determines the HME's total heat capacity, is the most important parameter influencing the performance of passive HMEs.

CONCLUSIONS

Increasing the HME's diameter is an effective way to improve an HME, as it yields higher performance and lowers breathing resistance. HMEs intended for use in warm or dry climates should contain more and those for use in cold humid climates should contain less hygroscopic salt.

Short and Long-Term Voice and Swallowing-Related Quality of Life in Patients Who Underwent Total Laryngectomy and Tracheoesophageal Puncture

Background

Voice and swallowing disorders can create a profound psychosocial impact on the patient’s quality of life. The focus of this study is to assess the psychosocial disabling effects on patients after total laryngectomy (TLP) using pre-validated surveys called the Voice Handicap Index 10 (VHI) for voice disorders and the Dysphagia Handicap Index (DHI) for swallowing disorders.

Methodology

This is a retrospective cohort study that was done on a total of 21 patients. The study was conducted at King Abdulaziz University Hospital between 2017 and 2022. The Cronbach’s alpha value was used to evaluate internal consistency reliability. The relationship between DHI, VHI, and demographic and clinical variables was analyzed by correlation analysis. A p-value of <0.05 was considered statistically significant, and all the tests were two-sided.

Results

The Cronbach’s alpha coefficient satisfied the internal consistency reliability for VHI and DHI for both total and their subscale scores. For DHI, the total score and emotional subscale obtained an alpha of greater than 0.9, indicating excellent internal consistency, whereas both physical and functional alpha scores indicated good internal consistency (α = 0.888 and α = 0.863, respectively). For VHI, the total score and physical subscale of the VHI had excellent internal consistency (α = 0.957 and α = 0.937, respectively), while the functional and emotional subscales had good internal consistency (α = 0.865 and α = 0.894, respectively). The total DHI scores, as well as the functional subscale scores, were significant (p = 0.033, p = 0.025, respectively) in terms of self-reported dysphagia severity. A moderately severe group (69.00 ± 19.17) had higher mean total scores, whereas severe individuals had higher subscale mean scores according to self-reported dysphagia severity. Self-reported dysphagia severity was as follows: normal (n = 3, 14.3%), mild (n = 4, 19%), moderate (n = 8, 38.1%), and severe (n = 6, 28.6%).

Conclusions

The disability caused by voice and swallowing disorders can be evaluated by VHI and DHI which have been statistically validated as reliable tools to assess the effects of dysphagia and dysphonia on quality of life. Patients after laryngectomy have higher mean DHI and VHI overall and functional subscale scores. However, this study failed to establish any relationship between clinical and demographical characteristics of the patients with DHI and VHI index.  

Tracheo Esophageal Prosthesis Insertion Under Endoscopic Guidance and Local Anaesthesia- Feasibility and Outcome

OBJECTIVES

Voice rehabilitation after laryngectomy is by tracheo esophageal puncture (TEP) and prosthesis insertion. Secondary TEP is very difficult due to neck fibrosis. Puncture under local anaesthesia with endoscopy guidance is a feasible option.

METHODS

Retrospective review of all laryngectomy patients from March 2009 till March 2019 was done and the methods of voice rehabilitation were assessed. The patients undergoing the procedure were classified according to the timing of insertion and type as primary insertion under general anaesthesia (Group P), secondary insertion under local anaesthesia (Group L), secondary insertion under general anaesthesia (Group G). The speech outcome and the procedure outcome were compared.

RESULTS

There were 148 patients who underwent laryngectomy, of which groups P, G, L were 12, 12 and 11. The rate of successful insertion was 100% in primary, 91.6% in secondary in general anaesthesia and 91% in secondary under local anaesthesia. All secondary TEP were done after surgery and radiotherapy. Complications related to the insertion techniques were minimal. Speech outcome were similar on intelligibility rating scale and longevity was not affected by the method.

CONCLUSION

TEP in local anaesthesia is feasible and has comparable outcome with TEP in general anaesthesia. Financial burden was very much less in group L compared to the other two groups.

A one-year time frame for voice prosthesis management. What should the physician expect? Is it an overrated job?

Management of late complications represents the main reason for reluctance in using voice prosthesis rehabilitation. The aim of this paper is to report our experience by describing the one-year management of a large cohort of patients in order to clarify how demanding management is in terms of burden on clinicians. Between June 2017 and June 2018, each access made at the Otolaryngology Clinic of our Institute for issues related to prosthesis by 70 laryngectomised patients rehabilitated by voice prosthesis was registered in a specific database. A review of the data provided information on the incidence, management and outcomes of adverse events encountered during the selected time frame. In addition, a T test was used to evaluate the differences between irradiated and non-irradiated patients and between primary and secondary tracheo-oesophageal-puncture. Leakage through the prosthesis was the most common cause for access (51.86%). The median number of accesses per patient per year was 3.47. The speech therapist autonomously managed 18.1% of accesses. The median number of accesses per patient per year needing a physician was 2.84. The median lifetime of the prosthesis was 4.85 months. Radiotherapy or modality (primary or secondary) of the puncture did not influence the number of accesses per year or the prosthesis lifetime. This retrospective analysis of results highlighted the most frequent issues and the most effective measures to deal with them, which allowed us to define a systematic algorithm to standardise and ease long-term outpatient management.

Periprosthetic Leakage in Tracheoesophageal Prosthesis: Proposal of a Standardized Therapeutic Algorithm

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.

Adjustable breathing resistance for laryngectomized patients: Proof of principle in a novel heat and moisture exchanger cassette

Background

Due to the heat and moisture exchanger's (HME) breathing resistance, laryngectomized patients cannot always use an (optimal) HME during physical exercise. We propose a novel HME cassette concept with adjustable “bypass,” to provide adjustment between different breathing resistances within one device.

Methods

Under standardized conditions, the resistance and humidification performance of a high resistance/high humidification HME (XM) foam in a cassette with and without bypass were compared to a lower resistance/lesser humidification HME (XF) foam in a closed cassette.

Results

With a bypass in the cassette, the resistance and humidification performance of XM foam were similar to those of XF foam in the closed cassette. Compared to XM foam in the closed cassette, introducing the bypass resulted in a 40% resistance decrease, whereas humidification performance was maintained at 80% of the original value.

Conclusions

This HME cassette prototype allows adjustment between substantially different resistances while maintaining appropriate humidification performances.

Cost-effectiveness analysis of using the heat and moisture exchangers compared with alternative stoma covers in laryngectomy rehabilitation: US perspective

BACKGROUND

This study aims to evaluate the cost-effectiveness of using heat and moisture exchangers (HMEs) vs alternative stoma covers (ASCs) following laryngectomy in the United States.

METHODS

A cost-effectiveness and budget impact analysis were conducted including uncertainty analyses using real-world survey data with pulmonary events and productivity loss.

RESULTS

HME use was more effective and less costly compared with ASCs. Quality-adjusted life years were slightly higher for HME-users. Total costs per patient (lifetime) were $59 362 (HME) and $102 416 (ASC). Pulmonary events and productivity loss occurred more frequently in the ASC-users. Annual budget savings were up to $40 183 593. Costs per pulmonary event averted were $3770.

CONCLUSIONS

HME utilization in laryngectomy patients was cost-effective. Reimbursement of HME devices is thus recommended. Utilities may be underestimated due to the generic utility instrument used and sample size. Therefore, we recommend development of a disease-specific utility tool to incorporate in future analyses.

Factors contributing to clinician training and development in the clinical area of laryngectomy and tracheoesophageal voice

BACKGROUND

It has long been recognized that tracheoesophageal speech (TES) rehabilitation after laryngectomy is a specialized area of practice for speech and language therapist (SLTs) due to the complex nature of patient presentation and the invasive components of the SLT's role in this area. Therefore, postgraduate experience and training is required to work competently and safely in this clinical area. However, it is generally acknowledged that the steps and processes followed by individual clinicians to achieve this training and clinical skill development are inconsistent and vary widely across services. There is a need to identify critical elements deemed most beneficial to clinical skill development in order to inform future training models.

AIMS

To explore clinicians' perceptions of factors that contribute to training and clinical skills development in the area of TES rehabilitation post-laryngectomy.

METHODS & PROCEDURES

All participants were SLTs working in an Australian clinical service, with a current or recent clinical caseload that included patients using TES. A total of 36 SLTs were recruited and then grouped by level of experience (novice n = 15, intermediate n = 7, experienced n = 14). Each participant took part in one small focus group with other participants of similar experience level. Ten focus groups were conducted, each of approximately 60 min in duration. A semi-structured interview guide was used to facilitate the discussion of issues relating to training in this area. Thematic analysis was used to analyse transcripts and identify themes.

OUTCOMES & RESULTS

Interviews identified six key themes, including: Learning with and from others; Formal programmes; Hands-on learning; Processes that influence training; and Individual influences. SLTs reported both positive issues and elements that were challenging across all five themes. The final (sixth) theme was identified regarding clinician perceptions of how this area differed to specialized training in other areas of the profession. The majority of themes were discussed equally by clinicians across all three experience levels.

CONCLUSIONS & IMPLICATIONS

Participants across all experience levels identified that multiple factors contributed to clinicians successfully gaining skills, understanding and competency when working in TES rehabilitation post-laryngectomy. These factors, when fully considered and incorporated into future SLTs training pathways and opportunities, have the potential to optimize competency, skill acquisition and maintenance in this area. What this paper adds What is already known on this subject While studies have considered the training, preparation and knowledge base of SLTs working in the clinical area of TES, the focus has predominantly been at the immediate postgraduate level or assessment of university course work. No studies have used a qualitative methodology to consider the reflections and perceptions of clinicians' training pathways and training needs across all levels of experience for this clinical area. What this paper adds to existing knowledge The results of this study build upon the existing body of literature regarding education and training in this area, determining factors SLTs feel are required to successfully gain skills, understanding and competency when working in TES rehabilitation. The findings highlight that training pathways and methods in this clinical area are an ongoing consideration for SLTs regardless of experience level and have the ability to impact on future competency programmes, training opportunities and delivery methods in this area. What are the potential or actual clinical implications of this work? Effective and ongoing postgraduate training programmes and professional development opportunities have the potential to positively impact on professional competence and confidence, patient safety and overall service delivery. Hence, the themes generated from this research highlight essential factors to include within training and professional development programmes for SLTs in TES rehabilitation. This information can be used to help optimize current training pathways for all experience levels.

Quality of life after total laryngectomy: impact of different vocal rehabilitation methods in a middle income country

INTRODUCTION

The impact of advanced laryngeal cancer and its extensive surgical treatments cause significant morbidity for these patients. Total laryngectomy impacts essential functions such as breathing, communication and swallowing, and may influence the quality of life as well as affecting the social life of laryngeal cancer patients.

OBJECTIVE

Describe the quality of life and analyze the factors associated with the reduced quality of life in patients who have undergone total laryngectomy.

METHOD

Observational cross-sectional study was carried out to evaluate the quality of life of patients who had undergone total laryngectomy due to laryngeal cancer. The fourth version of the UW-QOL Quality of Life Assessment Questionnaire from Washington University, validated for Portuguese, was used.

RESULTS

The study population was 95 patients, and the mean composite score of the QOL was 80.4. In the subjective domains the majority of the patients (38.9%) reported they felt much better at present compared to the month before being diagnosed with cancer. When questioned about how they evaluated their health-related quality of life, there was a predominance of those who considered it good (43.2%), and most considered they had a good quality of life (46.3%) considering personal well-being. The overall quality of life was considered good to excellent by 83.2% of the patients. Patients with tracheoesophageal prosthesis reported a better quality of life, compared to patients using an electrolarynx or esophageal voice.

CONCLUSION

The high mean value of the composite score for quality of life revealed that the patients assessed their quality of life positively. The absence of vocal emission was the only variable associated with a lower quality of life within the composite score according to the UW-QOL questionnaire.

Women's perspective on life after total laryngectomy: a qualitative study

BACKGROUND

Physical and psychosocial challenges are common after total laryngectomy. The surgery leads to lifelong changes in communication, airway, swallowing and appearance. As we move towards health models driven by patient-centred care, understanding the differential impacts of surgical procedures on subgroups of patients can help improve our care models, patient education and support systems. This paper discusses the experiences of women following total laryngectomy.

AIMS

To gain an insight into the impact of total laryngectomy on women's daily life while identifying their specific rehabilitation needs.

METHODS & PROCEDURES

This paper is based on in-depth, semi-structured interviews with eight women who had undergone total laryngectomy. These interviews were conducted with women at least 1 year after they had undergone total laryngectomy, and the participants did not have recurrent disease. Using an interview guide, participants were encouraged to discuss their everyday experiences, while also focusing on issues typical to women. The transcribed interview data were analysed by thematic analysis, taking interpretative phenomenological analysis as a lead.

OUTCOMES & RESULTS

The interviews revealed three main themes: disease and treatment as a turning point, re-establishing meaningful everyday activities, and persistent vulnerability. Participants reported experiencing challenges in their rehabilitation process due to physical disabilities, dependency on others and experienced stigma. Women-specific challenges arose in dealing with the altered appearance and voice, performing care activities, and the spousal relationship (including intimacy).

CONCLUSIONS & IMPLICATIONS

Women who undergo total laryngectomy are likely to experience issues in returning to work, the performance of informal care-work, the spousal relationship, intimacy and social interaction due to stigmatization. Medical pretreatment counselling and multidisciplinary rehabilitation programmes should help patients form realistic expectations and prepare them for the changes they will face. A gender- and age-matched laryngectomized patient visitor can contribute to this process. Rehabilitation programmes should incorporate the partner and offer psychosocial support for women following total laryngectomy to return to their former roles in family life, social life and work-related activities.

Perioperative Nursing of Patients with Reoperation of Recurrent Parathyroid Carcinoma Invading the Upper Digestive or Respiratory Tract

Objective

The aim of this study was to summarize the perioperative nursing care of patients with recurrent parathyroid carcinoma.

Methods

A retrospective analysis of 10 patients with recurrent parathyroid carcinoma was performed. The clinical data, diagnosis, treatment process, and nursing process (including clinical nursing intervention of various complications) were analyzed. The nursing experience and methods were discussed, summarized, and analyzed.

Results

A total of 10 patients were reviewed (male : female 7 : 3; aged 48.6 ± 14.60 years). The mean interval between the initial operation and reoperation was 2.23 ± 1.65 years. The mean number of operations was 4.00 ± 1.41. Invasion of the trachea or esophagus was evident in 7 patients, larynx in 6 patients, recurrent laryngeal nerve in 1 patient, and cyclic cartilage in 2 patients. Serum calcium range was 3.20-4.68 mmol/L, and parathyroid hormone (PTH) range was 860-2830 pg/ml at admission. 6 patients underwent prophylactic tracheostomy, 2 patients underwent partial laryngectomy, and 2 patients underwent total laryngectomy. 1 patient experienced temporary water-electrolyte disorder and hypoproteinemia. The median serum calcium was 2.28 mmol/L (1.66-3.18 mmol/L) and median PTH level was 82.60 pg/ml (63.70-900.00 pg/ml) postoperatively. Serum PTH and calcium were still higher than the upper limit of normal in 2 patients after surgery. 2 of the other 8 patients relapsed within 8-11 months, and 6 patients remained normal for 11-40 months.

Conclusion

For patients with reoperation of recurrent parathyroid carcinoma, high-quality, reasonable, and careful perioperative nursing ensured a successful operation and optimized outcome.

Speech and language therapists' reflections on developing and maintaining confidence in tracheoesophageal speech rehabilitation

BACKGROUND

The management of tracheoesophageal speech (TES) rehabilitation is an area of speech and language therapists' (SLTs) clinical practice where knowledge and skills are primarily developed through postgraduate workplace experience and training. Although recent research suggests clinicians in Australia perceive there is adequate access to workplace training, little is known about how clinicians develop and/or maintain clinical confidence when working in this specialist caseload.

AIMS

To investigate factors that contribute to development of clinician confidence as well as the factors that impact on improving and maintaining confidence when working in the clinical area of TES rehabilitation.

METHODS & PROCEDURES

SLTs working in an Australian clinical service and in a current or recent caseload including patients using TES were eligible to participate. A total of 36 SLTs were recruited and then grouped by level of experience (novice n = 15, intermediate n = 7, experienced n = 14). Ten focus groups of 60-min duration were conducted each with three to four participants from the same experience level. A semi-structured interview guide was used to facilitate the discussion of issues relating to training and confidence; however, only the content pertaining to clinical confidence is reported. Thematic analysis was used to analyse the transcripts.

OUTCOMES & RESULTS

Four themes were identified as contributing to the development of confidence: training, exposure, accessing support and mentorship, and leadership opportunities. Three themes were identified as critical for improving or maintaining clinical confidence: ongoing management of a caseload, ongoing support and further learning. An additional overarching theme was the desire for SLTs to classify or quantify their level of confidence, typically using a numeric scale or in years of clinical experience. The impact of varying contexts and caseloads on confidence levels was highlighted by all participants, but particularly those in the novice focus groups.

CONCLUSIONS & IMPLICATIONS

The findings highlight the fact that the acquisition and maintenance of confidence is an ongoing consideration for SLTs, both those starting out and those with years of clinical experience. With patient presentation increasing in complexity, the importance of understanding contributing factors for gaining and maintaining confidence should be considered alongside postgraduate training and the provision of ongoing support for SLTs working in this specialized clinical area, regardless of experience level.

Factors influencing clinical consistency and variability in voice prosthesis management

PURPOSE

Anecdotally it is recognised that management of tracheoesophageal speech (TES) post-laryngectomy varies between speech language pathology (SLP) services and clinicians. This study reviewed patterns of practice for TES management to examine patterns of practice and explore factors influencing variability.

METHOD

A national survey was completed by SLP's from clinical services which manage TES. This online survey examined demographic and caseload information, initial voice prosthesis (VP) placement and procedures, VP cleaning and care recommendations, humidification management, equipment and service provision, and service delivery options at each site.

RESULT

Lead clinicians from 34 sites (85% response rate) responded. Most clinical practice regarding initial VP insertion and management, as well as the timing and delivery of voice rehabilitation was highly consistent. Patient use of antifungal medications, TES and associated equipment provision, humidification management immediately post-surgery and some aspects of initial VP insertion were variable between services. The nature of the clinical setting, equipment funding and level of research evidence influenced variability in practice.

CONCLUSION

Variability exists in a number of aspects of practice across Australian services offering TES management. Sources of variability need to be addressed nationally to ensure there is consistent, quality care available for all patients.

Interdisciplinary interventions in the perioperative rehabilitation of total laryngectomy: an integrative review

The aim of this study was to use the scientific literature to identify interdisciplinary interventions for rehabilitation during the perioperative period for cancer patients who underwent total laryngectomy. We systematically researched controlled descriptors: laryngectomy, patient care team/education, patient care team/manpower, patient care team/methods, patient care team/utilization and rehabilitation. We performed a qualitative narrative synthesis and identified 549 articles. Of these, 113 were duplicates, 398 were excluded during the analysis of the title and abstract, 1 was excluded for unfeasibility of access, and 4 were excluded after reading the article in full, resulting in 33 included articles. The articles addressed different types of interdisciplinary actions, such as vocal, olfactory, pulmonary and alimentary rehabilitation; comparisons of prosthetic devices; and descriptions of practices for total laryngectomized patient rehabilitation. Although the interventions found in the literature were effective in the rehabilitation of the total laryngectomized patient, their interdisciplinarity was not evidenced but was highlighted in these studies as a factor for improvement in terms of practical assistance and quality of life.

Analysis of Factors Affecting the Longevity of Voice Prosthesis Following Total Laryngectomy with a Review of Literature

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.

Voice and swallowing after total laryngectomy

BACKGROUND

Voice and swallowing problems are often seen in patients with advanced larynx cancer, after total laryngectomy (TL) and chemo/radiotherapy. The aim of this study was to determine the occurrence of voice and swallowing problems in patients who have been laryngectomised and investigate if these symptoms were related to age, time after TL, radiotherapy and TNM-classification. In addition, we studied how often the patients changed their voice prostheses and the need of therapeutic interventions after TL.

METHODS

Forty-five patients were included in the study and completed the Swedish version of the Sydney Swallow Questionnaire and the Voice Handicap Index-T.

RESULTS

Swallowing problems were reported by 89% of the patients and moderate-to-severe voice handicap was reported by 66%. Most of the subjects who had dysphagia also presented voice problems (r_s = 0.67 p ≤ .01). Additional therapeutic interventions to manage problems with voice and/or swallowing after TL were required in 62% of the patients.

CONCLUSIONS

Swallowing and voice problems after TL are common. Thus, the preoperative information and assessment of these functions, as well as the treatment and the post-operative rehabilitation should be evaluated and optimised to provide better functional results after treatment of advanced larynx cancer.

3D simulation of an audible ultrasonic electrolarynx using difference waves

A total laryngectomy removes the vocal folds which are fundamental in forming voiced sounds that make speech possible. Although implanted prosthetics are commonly used in developed countries, simple handheld vibrating electrolarynxes are still common worldwide. These devices are easy to use but suffer from many drawbacks including dedication of a hand, mechanical sounding voice, and sound leakage. To address some of these drawbacks, we introduce a novel electrolarynx that uses vibro-acoustic interference of dual ultrasonic waves to generate an audible fundamental frequency. A 3D simulation of the principles of the device is presented in this paper.

T3-T4 laryngeal cancer in The Netherlands Cancer Institute; 10-year results of the consistent application of an organ-preserving/-sacrificing protocol

BACKGROUND

Both organ-preserving concurrent (chemo)radiotherapy ((C)RT) and organ-sacrificing surgery (total laryngectomy) are used for treatment of advanced laryngeal cancer. The purpose of this study was to present the assessment of our treatment protocol for T3 (C)RT and T4 disease (total laryngectomy + postoperative RT).

METHODS

We conducted a retrospective cohort study in 182 consecutive patients (1999-2008). The primary outcome was overall survival (OS) in relation to stage and treatment.

RESULTS

One hundred two patients received RT (82.4% T3), 20 patients CRT (60.0% T3), and 60 patients total laryngectomy + RT (91.7% T4). Five-year OS: T3 52%, T4 48%, for RT 50%, for CRT 43%, and for total laryngectomy + RT 52%. Five-year laryngectomy-free interval was 72% after RT, and 83% after CRT.

CONCLUSION

There were no differences in survival according to T classification or treatment modality. Because the majority of T3 laryngeal cancers were treated with (C)RT and the majority of T4 with total laryngectomy + RT, this gives food for thought on whether the present protocol for T3 laryngeal cancer is optimal.
