The ethics of performance care: A pragmatic feminist analysis of policy for singing voice rehabilitation.

INTRODUCTION: This paper uses pragmatic feminist poststructuralism to explore how ethical theory is applied to singing voice rehabilitation by specialist singing teachers. METHODS: A critical literature review examines the relationship between traditional and feminist ethical theories and their potential impact on practice. Themes have been extracted from the literature to create an intersectional feminist poststructural analysis framework, facilitating a document analysis of the foundations of three policy documents currently available to singing voice rehabilitation specialists. Poststructural deconstructivism was applied to thematic analysis to consider the impact of ethical theories on policy and practice. FINDINGS: Policies we found to be rooted in traditional enlightenment ethics, with a focus on hyper-rationality, androcentrism and legalism. Person-centred care ethics was found to be lacking in all documents. Contrary to best-practice recommendations documents failed to provided practical guidelines for practitioners. CONCLUSION: Findings indicate adopting an intersectional feminist ethical policy could improve existing documents via a move from legislation and authority towards care and reflexivity.

Integration of Dysphagia Therapy Techniques into Voice Rehabilitation: Design and Content Validation of a Cross-Therapy Protocol.

BACKGROUND: The intricate relationship between swallowing and phonation, sharing anatomical and physiological substrates, underscores a clinical demand for integrated therapeutic approaches. Existing interventions often address these functions in isolation, overlooking their interconnected dynamics. OBJECTIVE: To design and validate a cross-therapy protocol incorporating dysphagia therapy techniques (maneuvers/exercises) into voice rehabilitation. This protocol aims to exploit the shared biomechanical components of swallowing and phonation to improve both functions simultaneously in patients with underlying hypofunctional laryngeal pathology. METHODS: A descriptive research design was employed, consisting of three phases: a comprehensive literature review and expert discussions in a German seminar format to conceptualize the protocol; detailed analysis and categorization of swallowing maneuvers/exercises; and content validation by a panel of seven experts through a structured evaluation instrument. The process integrated motor learning and exercise physiology principles to ensure the protocol's clinical applicability and theoretical coherence. RESULTS: The developed cross-therapy protocol incorporates four core swallowing therapy techniques to voice therapy procedures. Selected swallowing therapy techniques target laryngeal excursion and vocal fold closure because they are critical components of swallowing and phonation. Expert validation yielded a Content Validity Coefficient exceeding 0.90 for most items, indicating high consensus on the protocol's relevance, clarity, and applicability. Adjustments were made based on feedback, enhancing the protocol's precision and user-friendliness. CONCLUSION: We present a novel, evidence-based therapy protocol for voice and swallowing difficulties resulting from hypofunctional laryngeal pathology. Its development marks a significant step toward bridging the gap between swallowing and voice therapy. Future empirical studies are needed to assess its effectiveness in clinical settings.

Analysis of Tracheoesophageal Voice after Total Laryngectomy: A Single Center Experience.

Background/Objectives: Tracheoesophageal voice is the most commonly used voice rehabilitation technique after a total laryngectomy. The placement of the tracheoesophageal prosthesis can be performed at the same time as the total laryngectomy (primary placement) or in a second procedure after surgery (secondary placement). The purpose of this study is to analyze the substitution voice in patients with a tracheoesophageal prosthesis, considering the influence of radiotherapy and timing of prosthesis placement (primary or secondary) on voice quality. Methods: A retrospective analysis was conducted of all patients who received a tracheoesophageal phonatory prosthesis after a total laryngectomy was performed. We assessed whether patients received radiotherapy and whether they had a primary or secondary tracheoesophageal prosthesis. For the voice analysis, maximum phonation time (MPT), INFVo, SECEL, AVQI, CPPS, harmonic to noise ratio (HNR), unvoiced fraction (UVF), and number of voice breaks (NVB) were evaluated. Results: A total of 15 patients (14 males and 1 female) with a mean age of 71.8 years (SD ± 7.5) were enrolled. Eight had a primary prosthesis placement and five did not receive radiotherapy. INFVo parameters I and Vo were higher in patients with a primary placement of the phonatory prosthesis (p = 0.046 and p = 0.047). Patients who received the prosthesis secondarily had a higher mean CPPS and lower mean AVQI. Conclusions: A secondary placement of the prostheses seems to result in a minimal advantage in voice quality compared to a primary placement. Radiation therapy, on the other hand, has no effect on voice quality, according to these preliminary data.

Sealing the Breach: A Surgical Solution for Tracheoesophageal Fistula With a Simple Two-Layer Closure.

Tracheoesophageal puncture (TEP) followed by voice prosthesis placement stands as the primary method for voice rehabilitation after laryngectomy, heralded for its effectiveness. While generally well-tolerated, the procedure does pose potential long-term complications. These include prosthesis valve leakage, scarring, and prosthesis displacement, all of which can impede phonation capabilities. Of these, prosthesis leakage emerges as the most critical concern, precipitated by the progressive widening of the fistula. This complication can precipitate aspiration pneumonitis, stemming from the loss of physical separation between the esophagus and trachea. This case series details three instances where persistent tracheoesophageal fistula arose following TEP, necessitating surgical intervention. Herein, we present the clinical manifestations, surgical approach employing a simple two-layer closure, and ensuing outcomes.

Total tracheoesophageal puncture failure: A scoping review of patient characteristics and etiologies.

OBJECTIVES: Tracheoesophageal prosthesis (TEP) is a common method for post-laryngectomy speech rehabilitation. Despite its common use, some patients ultimately fail TEP rehabilitation. TEP dysfunction negatively affects quality of life due to poor voice quality and need for repeated interventions to restore TEP function. Occasionally, voice rehabilitation with TEP is completely unsuccessful. We performed a scoping review to characterize the main reasons for total TEP failure, in hopes of guiding selection of optimal TEP candidates. STUDY DESIGN: Scoping review using PubMed of all English language articles from 1990 to 2020 addressing causes of TEP failure. METHODS: This scoping review followed the population, intervention, comparison, outcome and study (PICOS) guidelines. Total TEP failure was defined as complete loss or abandonment of TEP voice or tract. A comprehensive search strategy using PubMed's MeSH subject headings and keywords was created. Causes and rates of failure were reviewed. RESULTS: Among 544 peer-reviewed journal articles reviewed for inclusion. Seventy articles met inclusion criteria, resulting in a total of 4928 TEP voice restoration patients for analysis. 15.2% of these patients had total TEP failure. The most common reasons for failure were dissatisfaction with voice (26.3%), leakage (17.9%), inadequate patient motivation (14.7%), comorbidities (14.2%), stoma problems (11.6%), and abandonment of TEP after dislodgement (10.6%). CONCLUSION: Common reasons for TEP failure included voice dissatisfaction, leakage, lack of patient motivation, patient comorbidities, and stoma problems. These factors should be considered when selecting candidates for TEP voice restoration.

Immunosuppressive protocols after laryngeal transplantation: a systematic review.

BACKGROUNDS: Larynx transplantation has been successfully performed four times, in 1998, 2010, 2015 and 2023 remained the ultimate goal of voice, feeding and breathing rehabilitation. OBJECTIVE: Immunosuppressive protocols used during the previous successful larynx allotransplantation are detailed. MATERIAL AND METHODS: A systematic review of the literature on PUBMED/Medline, Cochrane and Embase was conducted. Articles relating to actual human larynx transplantations were included. RESULTS: Bibliography search gathered N = 10 publications related to the performance and follow-up of human laryngeal transplantations. N = 8 publications were included corresponding to N = 3 actual human larynx transplantations performed in 1998 and 2010 in the USA and in 2015 in Poland. Immunosuppression protocols, induction and maintenance strategies, rejection monitoring and history of all the three previous laryngeal grafts were detailed. CONCLUSIONS: Beyond the surgical prowess, larynx transplantation is feasible and associated with a reasonably successful outcome when compared to other solid organ transplants. Immunosuppressive regimen protocols and technologies for the monitoring of the organ viability have evolved. SIGNIFICANCE: The reevaluation of this surgical option serves as the reminder of the critical necessity to implement a meticulous immunosuppression protocol when transplanting this inherently immunogenic composite organ, the larynx.

Long-Term Complications of Tracheoesophageal Voice Prosthesis.

Background: The aim of our multicenter retrospective study was to evaluate the long-term complications associated with primary and secondary tracheoesophageal puncture (TEP) in patients who underwent total laryngectomy (TL) for laryngeal cancer and were subsequently rehabilitated to phonatory function with tracheoesophageal speech (TES). Materials and Methods: To evaluate the long-term outcomes and complications of TEP, the following data were collected: mean time of prosthesis replacement, mean time of onset of complications, type of complications, and type of failure. Results: Complications occurred in 18 out of 46 patients (39.2%) with primary TEP and in 10 out of 30 patients (33.4%) with secondary TEP, out of a total of 76 enrolled patients. Common complications included prosthesis leakage, fistula leakage, granulation, and prosthesis extrusion. Prosthesis replacement due to fistula leakage or prosthesis extrusion was observed exclusively in the group of patients with primary TEP. Among the 28 patients (35.7%) who experienced complications, rehabilitation with TEP failed in 10 cases, primarily due to abandonment and spontaneous fistula closure. Conclusions: TEP, both primary and secondary, represents a valid option for vocal rehabilitation in patients undergoing TL. However, identifying prognostic factors that could influence the success of TEP would be beneficial to allow a targeted rehabilitation process.

Three-dimensional reconstruction of King Henri IV's paranasal sinuses and mastoid cells.

PURPOSE: The preserved head of King Henri IV of France (life 1553-1610, reign 1589-1610) has survived to the present day thanks to high-quality embalming and favorable conservation conditions. The aim of this study was to examine Henry IV's upper resonant cavities and mastoids using an original and innovative forensic three-dimensional segmentation method. METHODS: The paranasal sinuses and mastoid cells of King Henri IV of France were studied by cross-referencing available biographical information with clinical and flexible endoscopic examination and computed tomography (CT-scan) imaging. The paranasal sinuses and mastoid cells were delineated and their volumes were assessed using ITK-SNAP 4.0 software (open-source). Graphical representations were created using Fusion 360® (Autodesk Inc., San Rafael, CA, USA) and MeshMixer® (Autodesk Inc., San Rafael, CA, USA). RESULTS: Paranasal sinus tomodensitometry revealed abnormalities in shape and number. Henri IV of France suffered from sinus aplasia. Neither the left sphenoid nor left frontal sinus contrasted sharply, and a remarkable pneumatization of the right clinoid processes extended throughout the height of the right pterygoid process. The total volumes of Henri IV's mastoid air-cells were estimated at 27 and 26 mL, respectively, for the right and left sides, exceeding the normal mean and the maximum of modern subjects by a wide margin. No sign of chronic ear or sinus condition was found. CONCLUSIONS: An innovative method has been developed in forensic medicine to establish hypotheses about the growth and respiratory conditions of the face.

Voice Rehabilitation After Laryngeal Transplantation: Own Experience.

BACKGROUND AND PURPOSE: Laryngeal transplantation (LT) remains an infrequently performed procedure due to well-defined and limited medical indications. The challenges include a very complicated surgery, continuous immunosuppressive treatment, as well as post-transplant rehabilitation of voice, speech, and swallowing. The aim of this paper is to describe a model of voice and speech rehabilitation after LT, based on our own experience. STUDY DESIGN: Observational study. METHOD: Presented here are the rehabilitation processes of two patients who had previously undergone LT as well as their pre- and postrehabilitation voice outcomes. Both patients underwent voice, speech, and swallowing rehabilitation in the fifth month after LT. RESULTS: One of the patients had a significant improvement in voice quality. While, the other did not regain his natural, sonorous voice, but he scored very high on a voice self-assessment test. CONCLUSION: Voice rehabilitation after LT is a complex and long-term process that requires the involvement of a team of specialists. The optimal anatomical conditions restored during surgery, the patient's motivation and the support of professionals make it possible to return to normal verbal communication.

Unlocking tracheoesophageal speech from pharyngoesophageal spasm: preliminary results of a videofluoroscopic-guided botulinum toxin A injection technique.

PURPOSE: The tracheoesophageal puncture for the voice prosthesis (VP) placement is the recognized gold standard in post-laryngectomy voice rehabilitation. Despite the development of specific intraoperative techniques, a subset of patients will suffer from poor functional outcomes due to pharyngoesophageal spasms (PES). This paper evaluates the functional outcomes after transcutaneous botulinum toxin type A (BTX-A) infiltration for PES with a videofluoroscopy-guided technique. METHODS: Since 2022, eight consecutive patients with VP and affected by PES were treated with BTX-A injection by a standard videofluoroscopic guided technique at the European Institute of Oncology, IRCCS (IEO) in Milan. A lidocaine test was performed pre-operatively to evaluate the potential effect of chemical neurectomy. All patients with positive lidocaine tests were injected with 50 IU of BTX-A (Allergan, Irvine, CA) according to the sites marked during the videofluoroscopy. Reported symptoms (VHI, SECEL), perceptual (INFVo), aerodynamic (MPT) and manometric parameters were collected before and after treatment. RESULTS: In all cases, BTX-A was performed as an outpatient procedure without complications. For seven patients, only one BTX-A injection was needed, while one patient required a re-injection. Subjective and perceptive improvement after BTX-A was significant for VHI, SECEL and INFVo. MPT showed significant improvement after a chemical neurectomy. After a mean follow-up of 6 months, all patients maintained a good TES quality. CONCLUSION: The videofluoroscopic guided BTX-A injection of the pharyngoesophageal tract showed to be a feasible and reproducible technique in all cases. The pharyngoesophageal videofluoroscopy allows defining of patients' anatomical landmarks that help the surgeon to perform a homogeneous injection, empowered by post-injection massage.

Laryngectomy: Phonation Alternatives and Their Impact on the Quality of Life.

Background The decision to consent to surgery is a life-changing moment. This study addresses the impact of total laryngectomy (TL) on phonation and its effect on the quality of life (QoL) of patients. The primary objective of this cohort study is to compare the alternatives in phonation rehabilitation, and the secondary objective is to identify concurrent predictors of vocal outcomes. Methodology To perform a comprehensive analysis, we reviewed data from patients who underwent TL with bilateral radical neck dissection in the Department of Otolaryngology, Head and Neck Surgery at Centro Hospitalar Universitário de Santo António between January 2010 and October 2022. Adult patients who consented to participate in the study and underwent subjective evaluation were included in this study. Data regarding clinical history was primarily collected. Statistical analysis was performed using SPSS version 26 (IBM Corp., Armonk, NY, USA). Different types of vocal rehabilitation formed the subgroups to be compared. An additional analysis was performed for baseline variables collected in the clinical records, and vocal outcomes were measured using the Self-Evaluation of Communication Experiences After Laryngectomy (SECEL) questionnaire. Furthermore, linear models taking SECEL scores as the outcome were developed. Results The first search identified a total of 124 patients operated during the study period. In total, 63 patients were alive at the time of the current follow-up, with 61 deaths (49%). Overall, 26 of the 63 alive patients completed the SECEL questionnaire. All patients were male. The mean age at diagnosis was 62.2 ± 10.6 years. The mean age at the time of subjective vocal assessment with the SECEL questionnaire was 66.3 ± 10.4 years. The mean time of follow-up after the initial diagnosis was 4 ± 3.8 years. A statistically significant difference was observed in esophageal speech (ES), which was inferior to other modalities (mean SECEL total score for ES: 46.6 ± 12.2 vs. mean SECEL total score for all other modalities: 33 ± 15.1; p = 0.03). The follow-up time correlated significantly with vocal function, as measured by the SECEL questionnaire (p = 0.013). Conclusions The SECEL questionnaire can be a valuable tool to evaluate QoL in laryngectomy patients, given its usefulness in assessing the psychological impact derived from vocal functionality in this group. ES appears inferior to other modalities regarding voice-related QoL.

Treatment of tracheoesophageal fistulas following laryngectomy by customized prostheses-A bicentric case series.

Objective: Tracheoesophageal fistulas (TEF) following laryngectomy cause immense restrictions due to the inability of oral feeding, loss of voice rehabilitation, penetration of saliva, and permanent need of inflatable tracheal cannulas. Patients are consistently in threat of fatal aspiration pneumonias. The failure rate of surgical approaches to close the fistulas is high and an ultima ratio option by customized silicone prostheses can be considered. Methods: A retrospective analysis of 26 patients with a TEF was performed. Results: The fistulas occurred in average 40 months after laryngectomy caused by an enlargement of the voice fistula in 17 patients and problems in wound healing in 6 patients. The mean diameter of the fistula was 32 × 18 mm. Eight patients were treated by a button-shaped and 18 by a tube-shaped prosthesis. Complete oral feeding was possible in 8 and additional feeding by percutaneous endoscopic gastrostomy tube in 16 patients. Voice rehabilitation by voice prostheses was possible in 18 cases. Fifteen patients died in the course of the treatment either due to oncological progression or other reasons. The median follow-up time of the patients alive was 36 months (max 88 months) with 2.2 protheses replacements in mean (max 11). Conclusion: The treatment of TEF by customized prostheses can be considered as an ultima ration option if other approaches had failed. At least, partial oral nutrition and voice rehabilitation as well as protection from aspiration can be achieved in the majority of the patients. Level of Evidence: 4-Case series.

A Human-Centered Design Approach to SOVTE Straw Phonation Instruction.

OBJECTIVES: Extensive research has demonstrated that straw/tube phonation exercises produce positive effects on the voice quality of the user. The purpose of this study was to explore pedagogical practices employed by a range of voice professionals when using SOVTEs by applying human-centered design approaches to examine workflow and communication between teachers and students. METHOD/DESIGN: The researchers conducted a series of five participatory role-playing workshop activities at a multi-disciplinary vocology conference that included speech-language pathologists, voice scientists, physicians, singing teachers, acting voice teachers, choral directors, and singers. Volunteers were asked to assume the role of teaching or learning straw phonation exercises. The other participants from each workshop were asked to provide written and verbal feedback regarding the teacher/student dynamics and what they found most important and relevant in terms of best practices for SOVTEs. Expert evaluators subsequently provided similar feedback based on video recordings of the workshops. RESULTS: While there was variability noted in teaching techniques and results, common themes emerged in the analysis. Successful and unsuccessful student and teacher techniques were identified by the workshop participants. Through the video analysis, the research team identified themes in instructional teaching, experiential learning, and straw articulation and mechanics. CONCLUSIONS: The benefits of straw/tube phonation exercises on voice quality have been well-established and are clear. As we continue to refine best practices in SOVTEs and, in particular, straw phonation, involvement of experts in HCD as part of multidisciplinary teams may lead to the eventual design of SOVTE tools that provide greater precision, consistency, and effectiveness both in clinical and pedagogical settings, and aid in the differentiation of SOVTE approaches within the taxonomy of vocal habilitation and rehabilitation techniques.

Indirect Vocal Therapy as a Treatment Program for Behavioral Dysphonia: A Pilot Study.

INTRODUCTION: Indirect vocal therapy (IVT) has tools that aim to modify an individual's behavior, emotional factors, and physical environment for restoring vocal quality. Then, vocal health guidance may promote the desire for caring about the voice and prevent or treat behavioral dysphonia. However, studies that used parts of IVT have shown conflicting results. Hence, the main objective of this study was to introduce an IVT program based on the taxonomy of Van Stan et al. [Am J Speech Lang Pathol. 2015;24(2):101-25]. The second objective of this study was to analyze the preliminary effects of the IVT program on vocal comfort through the self-assessment of vocal fatigue, vocal symptoms, vocal handicap, and vocal quality in patients diagnosed with behavioral dysphonia. METHOD: This is an experimental, analytical, and prospective pilot study. Nine participants (five women; four men) aged between 18 and 50 years with behavioral dysphonia participated in this study. They underwent the IVT program with guidance about vocal health, general health, emotional factors, and motivation. The therapy was implemented twice per week, totalizing eight sessions, each lasting 35 min. Participants were assessed before therapy started (M1), after it ended (M2), and 1 month after as a follow-up (M3). As assessment, participants filled in the Vocal Fatigue Index (VFI), Voice Symptoms Scale (VoiSS), and Vocal Handicap Index-30 (VHI-30). Additionally, they had their voices recorded for acoustic measures (i.e., cepstral peak prominence-smoothed, alpha ratio, and L1-L0) and auditory-perceptual analysis using the GRBASI scale. RESULTS: The acoustic measures and auditory-perceptual analysis showed no significant differences between the assessment moments. The auditory-perceptual analysis showed a mild deviation in participants' vocal quality. The participants' scores of the VFI, VoiSS, and VHI were lower in M2 and remained lower in M3. CONCLUSION: The IVT program had positive results in voice-related self-assessment and vocal comfort. However, further studies are necessary to elucidate its effects on the vocal quality of participants with behavioral dysphonia.

Does Prophylactic Replacement of Voice Prosthesis Make Sense? A Study to Predict Prosthesis Lifetime.

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.

Acoustic Characterization of the Voice With a Tracheoesophageal Speech in Laryngectomized Patients. Similarities and Differences With the Laryngeal Voice.

BACKGROUND: Voice with tracheoesophageal speech (TES) is an effective, widely recognized option to restore the ability of oral communication to laryngectomized patients. In this study, we try to characterize the TES, taking account different variables and making an acoustic analysis of voice with TES versus laryngeal voice (LV). METHODS: We compare different acoustic and subjective variables like GRABS or VHI in 34 patients with TES and 31 controls with LV. RESULTS: Patients with TES reach a good quality of voice with F0, F1, F2, F3, Jitter, Shimmer, and Yanahigara test similar to control group. Furthermore, the subjective scales show a good perception of voice for patients and examiners. CONCLUSIONS: Patients with tracheoesophageal voices show acceptable voice results, in many cases reaching to be near to controls with LV.

The Dynamic Tracheoesophageal Prosthesis Length.

OBJECTIVE: In a postlaryngectomy patient, tracheoesophageal (TE) speech is considered to be the most effective and preferred method of communication. Previous research has demonstrated that despite an appropriately sized TE prosthesis placement at the time of puncture, there are a portion of patients that require resizing postoperatively. The purpose of this study was to report on the variability of the tracheoesophageal prosthesis length. STUDY DESIGN: Retrospective chart review. SETTING: Tertiary care academic medical center. METHODS: This was a retrospective chart review of 62 patients who underwent secondary tracheoesophageal puncture (TEP) at a tertiary care academic medical center from January 2008 to November 2019. Patient demographic information, average changes in prosthesis length, number of prosthesis adjustments, and timing of prosthesis exchanges were collected. RESULTS: 62 patients met criteria for study inclusion. Mean age was 61.96 years old with 49 being male (79%) and 13 (21%) females. Overall change in prosthesis length was - 3.85 mm ± 3.58 with time to first prosthesis change at 2.29 months ± 2.73. There was an average of 4.37 changes ± 3.43 before reaching a stable length. Twenty-six patients (41.9%) had increases in their prosthesis length resulting in closure of the tracheoesophageal fistula requiring seven patients (11.3%) to return to the operating room for repuncturing. History of smoking (P = 0.02), Blom-Singer prosthesis type (P = 0.03), and larger diameter (P = 0.01) appeared to be predisposing factors for a fluctuating prosthesis length. CONCLUSION: Tracheoesophageal prosthesis length decreases over time for secondary punctures, requiring adjustments with a speech language pathologist. There are a clinically significant portion that have fluctuations in prosthesis length resulting in an increased risk for requiring re-puncturing.

Voice rehabilitation with voice prosthesis: Long term results, complications and risk factors.

OBJECTIVES: Despite the advances in surgical and non-surgical organ preservation treatments, total laryngectomy (TL) remains the most effective treatment in advanced larynx cancer and as salvage procedure in chemoradiation failure. One of the most devastating sequel after TL is loss of voice. Voice prosthesis (VP) is currently the preferred choice for voice rehabilitation. The purpose of this study is to identify VP complications, its lifespan and factors that influence the longevity of the VP. METHODS: We performed a retrospective study at a Tertiary University Hospital. Medical records of patients that underwent total laryngectomy, between January 1st of 2008 and 31st of December of 2017 were analyzed. RESULTS: Of the 84 patients that underwent laryngectomy, 60 had VP. The average age at the time of surgery 60.2 years old and there was a male preponderance (57:3). The mean lifespan of the prosthesis was 7.53 months. Leakage through the prosthesis was the most common reason for replacement of the prosthesis, followed by leakage around the prosthesis. Follow up time and manual suture were associated with prosthesis replacement. There was no significant relationship between the staging, tumor location or adjuvant radiotherapy and number of prosthesis replacement or its lifespan. CONCLUSIONS: Rehabilitation after TL is of major importance to improve quality of life after surgery. Tracheoesophageal puncture with voice prosthesis is a safe procedure for vocal rehabilitation and was performed in the majority of patients in our study. Follow-up time and type of suture were the main determinants of the lifespan of the prosthesis.

A Multidisciplinary Approach to Secondary Tracheoesophageal Puncture for Voice Prosthesis Insertion Using Flexible Esophagoscopy.

BACKGROUND: Tracheoesophageal puncture (TEP) with voice prosthesis (VP) insertion is the gold standard of surgical voice restoration in postlaryngectomy patients. The conventional technique involves rigid esophagoscopes and trocar performed by ENT surgeons alone, with technical limitations encountered in patients with cervical abnormalities - in particular those with free or rotational flap reconstructions and postradiotherapy strictures. We report our technique using flexible endoscopy which we show to be feasible and without major safety events, as a possible consideration in the anticipated difficult TEP. METHODS: Our study describes a multidisciplinary approach to secondary TEP involving a combined upper gastrointestinal (UGI) and (Ear, Nose, and Throat) ENT procedure, under the guidance of flexible esophagoscopy, with intraoperative involvement of the speech pathologist to guide VP insertion and placement. The procedure was performed with ease without major complications. RESULTS: We identified nine postlaryngectomy and laryngopharyngectomy patients in our institution who underwent secondary TEP with VP insertion using flexible esophagoscopy and multidisciplinary intra-operative involvement. All patients had pharyngeal reconstruction, including radial forearm free flap (n = 4), pectoralis major rotational flap (n = 3), and anterolateral thigh flap (n = 2). Eight out of nine patients underwent adjuvant radiotherapy. The technique was successfully performed in all patients. There were three cases of early TEP displacement in two patients, of which one patient had a successful repeat procedure. We found the technique advantageous in terms of feasibility and practicality compared to the conventional approach, and without intraoperative difficulties encountered in achieving the desired field of views or navigating the challenging anatomy in a free flap and post-radiotherapy patients. This includes distorted cervical anatomy, the presence of bulky and hair-bearing flap skin, and stricture formation. Minor complications in our cohort included pharyngo-esophageal spasm, TEP displacement, granulation tissue, and peri-prosthetic leaks. CONCLUSION: Our multidisciplinary approach to secondary TEP was performed with flexible esophagoscopy without major related complications. The technique is advantageous in the surgical approach to VP insertion in postlaryngectomy and laryngopharyngectomy patients who have had radiotherapy or pharyngeal reconstruction. It allows for safe anatomical insertion and thorough evaluation of the upper aerodigestive tract for comorbid benign or malignant esophageal pathology.

Factors Affecting the Lifetime of Third-Generation Voice Prosthesis After Total Laryngectomy.

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.
