A Case of Tracheogastric Puncture Using Transnasal Esophagoscopy After Total Laryngopharyngoesophagectomy and Gastric Pull-Up Reconstruction

Voice rehabilitation after total laryngopharyngoesophagectomy is a significant challenge, especially when accompanied by gastric pull-up reconstruction. In 2021, a study revealed that tracheoesophageal puncture is also safe and feasible option for voice rehabilitation in patients who underwent gastric pull-up surgery. Here, we report for the first time in South Korea a case that represents an instance of voice prosthesis insertion after gastric pull-up surgery. The case demonstrates the feasibility and safety of voice prosthesis insertion in patients who undergo total laryngopharyngoesophagectomy and gastric pull-up surgery, providing evidence that voice prosthesis insertion is achievable and can be performed in the outpatient setting using transnasal esophagoscopy.

The Benefits of Silicone Laryngectomy Tubes at the Time of Laryngectomy-A Case Series Spanning 17 Years.

Although total laryngectomy (TL) is a well-established surgical procedure with clear functional or oncologic indications, the peri- and postoperative care for those undergoing TL is variable, particularly regarding postlaryngectomy tracheostoma management. This study examined TL outcomes from a single institution with the immediate perioperative use of soft silicone laryngectomy tubes. More specifically, we explored potential complications associated with immediate perioperative use of a flexible laryngectomy tube (LaryTube and StomaSoft) and the use of heat and moisture exchange (HME) devices in association with peri- and postoperative care. A case series including all patients undergoing TL by one primary surgeon at a tertiary care hospital between 2006 and 2023 were assessed. Variables of interest included hospital average length of stay (LOS) in hospital, use of laryngectomy tube and an HME, primary tracheoesophageal puncture voice restoration at time of TL, discharge feeding, stoma-related complications, and overall complications. Seventy-two patients were included over the study period, and all utilized a laryngectomy tube and HME in the perioperative period without complications. Fifty-six patients (77.7%) had concurrent neck dissections and nine (15%) underwent total laryngopharyngectomy. Sixty-two patients (86%) underwent TL for squamous cell carcinoma of the larynx or hypopharynx and 35 of these (56%) were salvage surgeries. Mean LOS was 8.4 (3-45) days, and 63 patients (88%) were discharged with nasal gastric tube feeding. Of the six patients (8%) who were readmitted for complications, zero (0%) were related to the laryngectomy tube or to stoma-related complications (e.g., dehiscence, infection, mucous plugging). No patient who utilized a laryngectomy tube and HME device in the perioperative period experienced stomal stenosis. Laryngectomy tubes combined with an HME can be employed safely and successfully in a high percentage of laryngectomy patients placed perioperative. No instances of postlaryngectomy tracheostoma stenosis occurred in association with perioperative laryngectomy tube with HME use. These collective data support the use of a laryngectomy tube with HME in the immediate perioperative period, with low risk of complications.

Chest Tube Placement of Secondary Tracheoesophageal Voice Prosthesis: Overcoming Challenging Anatomy in the Laryngectomy Patient.

Introduction: Total laryngectomy is used to cure advanced larynx cancer in many patients. The removal of the larynx requires the rehabilitation of the patient's ability to communicate, and one common method is to place a tracheoesophageal voice prosthesis (TEP) as a secondary procedure after the patient has completed cancer treatment. The traditional technique utilizes a rigid esophagoscope for access, but this can prove difficult in many patients who have kyphosis, scarring of the neck, or trismus. We describe a technique to allow TEP placement in these challenging patients that does not utilize rigid esophagoscopy to access the tracheoesophageal puncture site. Methods: For more than 15 years, the senior authors of this study have used this technique in patients in whom traditional methods of TEP with rigid esophagoscope were unsuccessful or not attempted due to the anticipated high probability of failure. The ease of this technique has prompted its use for all patients undergoing secondary TEP placement in their practice. The technique is described in detail in the Methods section below. Results: The described method has been successfully utilized to place TEPs in many patients with challenging anatomy. There have been no failed placements, including a patient with severe trismus who was able to have a TEP placed by placing the chest tube and flexible endoscope transnasally. Further, because of precise visualization and ease of the technique, there have been no observed complications of injury to the pharyngoesophageal lumen or creation of a false passage. Conclusion: The use of a chest tube and flexible scope allows for the protection of the pharyngoesophageal lumen, precise visualization and placement of the puncture, and avoidance of a false tracheoesophageal passage, all while minimizing the need for extension of the patient's neck. This has proven ideal for patients suffering the consequences of cancer treatment such as cervical scarring, fibrosis, kyphosis, and trismus.

Does a Submental Airway Compared to a Tracheostomy Reduce Length of Stay in Craniomaxillofacial Trauma?

Patients with craniomaxillofacial trauma (CMT) are at increased risk of airway compromise and may necessitate airway stabilization via a tracheostomy (TO) or cricothyroidotomy. The submental airway (SMA) is an alternative airway and can avoid complications related to TO. The purpose of this study was to compare the SMA to the TO with respect to hospital length of stay (LOS) and number of days with an advanced airway, termed airway days (ADs). This single-center retrospective cohort study included subjects with isolated CMT who required operative treatment with either a TO or SMA at Harborview Medical Center. Subjects were excluded if they required a TO for reasons other than treating their CMT. The predictor variable was airway type. Primary outcome variables were LOS and ADs measured as number of days between admission and discharge dates, and days between establishment of airway and extubation or decannulation dates, respectively. Covariates included age, sex, American Society of Anesthesiology classification, weight, body mass index, substance use, hospital status, facial injury severity scale scores, and airway placement location. Bivariate analysis using independent t test, Mann-Whitney U test, and multiple linear regression analyses were used. P value of <.05 was considered significant. Of the 14 subjects identified, 6 underwent a TO and 8 a SMA. The mean LOS in the TO group was 20.3±15.8days versus 3.9±4.7days in the SMA group (P=.02). Mean AD in the TO group was 13.2±8.4 versus 0.6±0.7 in the SMA group (P=.01). The TO group had a higher number of operations at 2.0±0.6 versus 1.1±0.4 with a SMA (P=.02). After linear regression analysis adjusting for sex, age, weight, and facial injury severity scale, there were no statistically significant differences between the groups. Compared to, SMA has a 5-fold decrease in LOS and 22-fold decrease in ADs on bivariate analysis. An SMA is a viable airway management option for operative treatment of isolated CMT. Further studies are warranted with a larger sample size.

Tracheostomy before and during COVID-19 pandemic.

The aim of the study was to provide insight into the influence of the COVID-19 on the frequency and characteristics of urgent and emergent tracheostomies (TS), comparing data collected both before and during the pandemic. Our two hypotheses were that during COVID-19, more TS were performed in the emergent setting and that during COVID-19 more TS were performed under general anaesthesia. The research was retrospective. The study period included the two years before and after the COVID-19 outbreak in Slovenia. Forty-one patients in each period met the inclusion criteria. Their medical charts were reviewed. The anamnestic, clinical, surgical and anaesthesiological data were collected. The two groups of patients from corresponding time periods were statistically compared. Predominantly men required the surgical resolution of acute upper airway obstruction (76% of patients). The causes for acute respiratory distress included head and neck cancer (62%), infections (20%), vocal cord paralysis (16%), and stenosis (2%). There were no statistically significant differences either in the (emergent/urgent) setting of TS or in the type of anaesthesia used. Both hypotheses were rejected. A statistically significant rise in use of the C-MAC laryngoscope during COVID-19 (from 3% to 15%) was reported. The outbreak of COVID-19 did not have a statistically significant effect on the frequency of performing emergent and urgent tracheostomies nor on the use of general or local anaesthesia. It did, however, require a change of intubation technique. Consequently, a significant rise in the use of the C-MAC laryngoscope was noted.

Surgery for locally advanced laryngeal cancer

Surgical options for locally advanced laryngeal cancer range from organ-preservation surgeries, such as transoral laser microsurgery and partial laryngectomy, to total or near-total laryngectomy with partial or total pharyngectomy. Herein, we describe preoperative workup, surgical technique for total laryngectomy, including stomal incision and design, laryngeal framework isolation and thyroid management, entry into the larynx and pharynx, tracheoesophageal puncture, and closure options. Early and late postoperative complications are considered. Lastly, conservation laryngeal surgical options, including vertical versus horizontal partial laryngectomy and transoral laser microsurgery are discussed.

Primary fit tracheoesophageal puncture in primary versus salvage laryngectomy: Short-term and long-term complications and functional outcomes.

Primary fit tracheoesophageal puncture (TEP) is widely preferred for individuals who have not undergone prior radiation. However, there is no consensus on the relative utility of primary-fit TEP in the setting of salvage laryngectomy. A retrospective, single-center review was conducted of individuals undergoing laryngectomy with primary fit TEP between 2012 and 2018. Multivariable analysis was conducted to compare short-term and long-term complications, as well as speech and swallowing outcomes, of those who underwent primary versus salvage laryngectomy. In this study, 134 patients underwent total laryngectomy with primary fit TEP. Aside from a higher rate of peristomal dehiscence (13.1% vs. 1.4%) found in the salvage group, there was no difference in incidence of all other complications, including pharyngocutaneous fistula formation. The groups had comparable speech and swallow outcomes. Primary fit TEP is a safe and effective surgical choice for individuals undergoing salvage laryngectomy who desire a voice prosthesis.

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.

Evidence-Based Recommendations in Primary Tracheoesophageal Puncture for Voice Prosthesis Rehabilitation.

Head and neck cancer, the seventh most common cancer worldwide, often affects the larynx, with a higher incidence in men. Total laryngectomy, a common treatment, results in the loss of phonation, and tracheoesophageal voice rehabilitation is the current rehabilitation method of choice. Despite ongoing debates regarding the timing of tracheoesophageal puncture (TEP), a crucial procedure for voice prosthesis placement, the secondary puncture continues to be the preferred choice in the majority of cases. This underscores the persistent controversy and the absence of consensus in this field. The aim of this manuscript was to define evidence-based recommendations regarding the procedure of primary TEP with voice prosthesis placement, establish the conditions and requirements for performing primary TEP, determine the indications and contraindications of primary TEP, as well as to define the complications and management of primary TEP. A total of 19 statements were formulated, with 78.95% of them having a Level of Evidence 4 and a Grade of Recommendation C. There is not sufficient evidence comparing the outcomes of primary TEP versus secondary TEP. Future studies with robust methodologies are needed to clarify the role of primary and secondary TEP in the rehabilitation of patients undergoing total laryngectomy.

A nomogram for predicting the necessity of tracheostomy after severe acute brain injury in patients within the neurosurgery intensive care unit: A retrospective cohort study

ObjectiveThis retrospective study was aimed to develop a predictive model for assessing the necessity of tracheostomy (TT) in patients admitted to the neurosurgery intensive care unit (NSICU). MethodWe analyzed data from 1626 NSICU patients with severe acute brain injury (SABI) who were admitted to the Department of NSICU at the Affiliated People's Hospital of Jiangsu University between January 2021 and December 2022. Data of the patients were retrospectively obtained from the clinical research data platform. The patients were randomly divided into training (70%) and testing (30%) cohorts. The least absolute shrinkage and selection operator (LASSO) regression identified the optimal predictive features. A multivariate logistic regression model was then constructed and represented by a nomogram. The efficacy of the model was evaluated based on discrimination, calibration, and clinical utility. ResultsThe model highlighted six predictive variables, including the duration of NSICU stay, neurosurgery, orotracheal intubation time, Glasgow Coma Scale (GCS) score, systolic pressure, and respiration rate. Receiver operating characteristic (ROC) analysis of the nomogram yielded area under the curve (AUC) values of 0.854 (95% confidence interval [CI]: 0.822–0.886) for the training cohort and 0.865 (95% CI: 0.817–0.913) for the testing cohort, suggesting commendable differential performance. The predictions closely aligned with actual observations in both cohorts. Decision curve analysis demonstrated that the numerical model offered a favorable net clinical benefit. ConclusionWe developed a novel predictive model to identify risk factors for TT in SABI patients within the NSICU. This model holds the potential to assist clinicians in making timely surgical decisions concerning TT.

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

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. 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 50IU 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. 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 6months, all patients maintained a good TES quality. 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.

Perforator-based chimeric ulnar forearm microvascular free tissue transfer reconstruction of post-radiated tracheoesophageal puncture fistulae.

Tracheoesophageal puncture (TEP) performed during total laryngectomy in the primary treatment of laryngeal cancer is the standard method for voice restoration. Following adjuvant radiotherapy, the TEP site can experience complications resulting in a tracheoesophageal fistula (TEF) with chronic leakage making oral alimentation unsafe due to aspiration. Here, we describe a technique using chimeric ulnar artery perforator forearm free flaps (UAPFF) in the reconstruction of these complex deformities. Four patients underwent chimeric UAPFF reconstruction of TEP site TEFs following primary TL with TEP and adjuvant radiotherapy. No flap failures or surgical complications occurred. Average time from end of radiotherapy to persistent TEF was 66 months (range 4-190 months). All patients had resolution in their TEF with average time to total oral diet achievement of 22 days (14-42 days). Chimeric UAPFF reconstruction is a safe and effective method to reconstruct recalcitrant TEP site TEFs.

Impact of long-term nasal airflow deprivation on sinonasal structures and chronic rhinosinusitis in total laryngectomy patients.

Total laryngectomy (TL) patients are good models in which to evaluate the effects of nasal airflow cessation on the sinonasal tract. Here, we evaluated changes in sinonasal structures and association with sinus opacification in the computed tomography (CT) images 3 years post-TL. Patients who underwent TL from 2005 to 2017 in a teaching academic center were reviewed retrospectively. Patients with a final follow-up CT taken less than 3 years after TL, tracheoesophageal puncture, inadequate CT image, or history of sinonasal surgery were excluded. The control group included patients who underwent a partial laryngectomy or hypopharyngectomy without requiring a tracheotomy for more than a month. Altogether, 45 TL patients and 38 controls were selected. The volume of all four paranasal sinuses, inferior turbinate soft tissue volume (ITSTV), maxillary sinus natural ostium (MSNO) mucosal width, and Lund-Mackay scores (LMS) were measured on preoperative and postoperative CT scans. The mean duration between surgery and the final CT scan was 6.3 ± 2.4 and 5.5 ± 2.3 years for the TL and control groups, respectively. Neither group showed significant changes in the four paranasal sinuses' volume or MSNO mucosa width. The ITSTV decreased significantly, from 4.6 ± 1.3 to 2.8 ± 1.1 mL (p < .001), in the TL group, regardless of the presence of nasal septal deviation, showing ITSTV reduction on both concave and convex sides. By contrast, the control group showed no significant changes in ITSTV. Postoperative LMS changes in both groups were insignificant. The number of patients with LMS aggravation or alleviation was the same in both groups, regardless of preoperative sinus opacification. Paranasal sinus structures and sinus opacification are not affected significantly by nasal airflow cessation; however, the inferior turbinate mucosa is affected by long-term discontinuation of nasal airflow. 4 (case-control study).

Objective evaluation of the pharyngoesophageal segment as a source of substitute phonation in patients after total laryngectomy

The study aimed to identify objective predictors of the successful voice rehabilitation after total laryngectomy to select the optimal method of voice restoration.Material and Methods. The study included 60 laryngectomized male patients who were stratified into 2 equal groups depending on the patient’s choice of voice restoration: tracheoesophageal puncture or esophageal voice. A comprehensive assessment of the qualitative and quantitative parameters of the pharyngoesophageal segment was carried out using the diagnostic procedures, such as: fiberoptic endoscopic evaluation of swallowing, high-speed video endoscopy, and high-resolution pharyngoesophageal manometry. The results of examination of the pharyngoesophageal segment were compared with the results of voice rehabilitation.Results. A significant difference in the resting pressure in the pharyngoesophageal segment between patients with successful and unsuccessful voice rehabilitation was found. The resting pressure in the pharyngoesophageal segment was higher in patients with unsuccessful voice rehabilitation than in patients with successful voice rehabilitation. Among patients with failed voice rehabilitation, 64 % had pseudodiverticula, 25 % had cicatricial strictures and 11 % had pharyngospasm. Pseudodiverticula were found only in patients who underwent vertical or apparatus pharyngeal closure. We described vibrating patterns of substitute phonation in laryngectomized patients and identified 5 different types of pseudoglottis. No significant differences between the methods of substitute phonation were found.Conclusion. The state of pharyngoesophageal segment is an objective predictor of successful substitute phonation and depends on the surgical technique of pharyngeal closure, the volume of cancer treatment and the course of the postoperative period. A comprehensive assessment of the qualitative and quantitative parameters of the pharyngoesophageal segment using fiberendoscopic, fuoroscopic studies and highresolution pharyngoesophageal manometry allows prediction of voice rehabilitation outcomes.

Hybrid primary puncture in stapler-assisted total laryngectomy.

In Video S1, a new surgical technique for hybrid primary tracheoesophageal (TE) puncture in stapler-assisted total laryngectomy is shown. The video describes the surgical steps of the procedure and illustrates some tips and tricks. The procedure incorporates an upper mini-pharyngotomy to enable retrograde placement of the voice prosthesis (VP), eliminating the need for rigid esophagoscopy. This has made it possible to exploit, without additional risks, the potential of the stapler combined with primary TE puncture and VP placement. In our experience, this hybrid procedure in stapler-assisted total laryngectomy is not related to adverse events such as pharyngocutaneous fistula (PCF), hypertonicity, and functional complications. Therefore, it can be considered a valid technique that allows for easy insertion of a primary voice prosthesis also in case of mechanical sutures.

Sternohyoid or sternocleidomastoid muscle flap for tracheoesophageal puncture closure in irradiated patients: A CARE case series

IntroductionA novel technique for tracheoesophageal puncture (TEP) closure is described in which the sternohyoid muscles are rotated and interposed between the tracheal and esophageal walls. The results of this technique are reported, following CARE guidelines, and compared with those obtained using the sternocleidomastoid flap. A literature review on the techniques previously described for TEP closure in irradiated patients is presented. Case seriesThe novel technique was performed in six patients in whom the infrahyoid muscles were preserved during total laryngectomy. All received adjuvant radiotherapy. Successful closure was achieved in three cases; in one case a small leak was noted after initial closure and was successfully managed with simple sutures; and the other two failures occurred in patients with diabetes. The sternocleidomastoid flap was performed in five patients (only one with previous radiation) and success was achieved in two patients. In another patient a micro-fistular orifice appeared six months after the operation. DiscussionThe sternohyoid muscles pose a low morbidity alternative to be considered in surgical TEP closure. Patient selection is a key factor to surgical success, and this technique should be reserved for small to moderate size fistulas and in the absence of multiple impaired wound healing conditions.

Protocolized awake secondary tracheoesophageal puncture with immediate voicing.

Tracheoesophageal (TE) puncture with voice prosthesis placement is a common method for vocal rehabilitation in patients who have undergone total laryngectomy. Tracheoesophageal voice prosthesis (TEP) placement after laryngectomy, known as secondary TE puncture, is traditionally done in the operating room, using rigid esophagoscopy. Traditional secondary TEP placement carries a number of downsides including risks associated with general anesthesia, high cost, and technical challenges associated with anatomical variables. As a result, in-office secondary TE puncture has become an increasingly utilized procedure with many advantages but currently lacks standardization. Here, we describe a kit-based, awake, in-office secondary TE puncture with primary TEP placement technique. This technique calls for an endoscopic snare in the event there is difficulty passing the guidewire in the cranial trajectory. No surgical technique videos demonstrating in-office secondary TE puncture currently exist. Here, we present a video tutorial of our technique, breaking down the procedure into 10 steps from analgesia to voicing.

Training for Awake, Office-Based Laryngeal Procedures-The Laryngology Fellow's Perspective.

The aim was to explore recent laryngology graduates' perspectives on their experience, competency, and challenges learning office-based procedures during fellowship training in the United States and Canada. Anonymous 22-item questionnaire survey was distributed electronically to fellowship-trained laryngologists having completed fellowship within past 5 years. Ninety fellowship-trained laryngologists between 2018 and 2022 were surveyed. Response rate was 48.9% (n = 44), 1 declined participation, with 20 different fellowship programs represented. Fellows were frequently provided the opportunity to act as primary surgeon for most procedures, except for laryngeal botulinum toxin injection, diagnostic laryngeal electromyography, trans-nasal esophagoscopy, secondary tracheoesophageal puncture, and high-resolution pharyngeal manometry. A majority reported high (n = 27, 62.8%) or moderate (n = 12, 27.9%) confidence with vocal fold injection augmentation. Various techniques were taught: transoral (74.4%), cricothyroid (74.4%), thyrohyoid (69.8%), transcartilagenous (14.0%), and catheter-needle (25.6%). Numerous statistically significant associations with independent procedure involvement and competence were identified. Laryngeal botulinum toxin injection was a procedure performed with high frequency but low volume of independent fellow involvement, and the procedure with which fellows reported wanting more practice learning. Most common training barriers included patient being awake, patient consenting to trainee performing the procedure, and the technical challenge/complexity of the procedure. Teaching methods/tools largely focused on informal debriefing (97.3%) and case by case troubleshooting (81.1%). Laryngology fellows are well trained with favorable perceived levels of competence for numerous office-based procedures, particularly vocal fold injection augmentation. Procedures for which fellows reported a low level of independent participation trended towards lower perceived competency. 5 Laryngoscope, 134:873-881, 2024.

Patterns of alaryngeal voice adoption and predictive factors of vocal rehabilitation failure following total laryngectomy.

We aimed to determine patterns of alaryngeal voice acquisition and predictive factors of vocal rehabilitation (VR) failure following total laryngectomy (TL) at a large Canadian tertiary care center. All consecutive patients having undergone a TL between January 1st, 2011 and December 31st, 2019, at the Centre Hospitalier de l'Université de Montréal were included. One hundred and ninety-seven laryngectomized patients were identified. Successful VR was achieved in 86 (59.0%) patients, while 59 (41.0%) failed to use a method of alaryngeal voice as their principal means of communication at 1 year postoperatively. The use of tracheoesophageal puncture (TEP) was associated with higher VR success rates (70.6%) when compared with the artificial larynx (48.6%), and esophageal voice (18.8%). The only independent predictor of VR failure on multivariate analysis at all time points was a low socioeconomic status. Failure to adopt an alaryngeal voice following TL is highly prevalent, despite comprehensive and free speech language pathologist services being offered at our center. A low resort to TEP at our institution and a poor acceptability and accessibility of alternative VR methods may contribute to this trend. The challenges of VR may be further exacerbated by the barriers linked to a lower socioeconomic status, which in turn may contribute to reduced candidacy for TEP.

The Influence of Stimulus Composition and Scoring Method on Objective Listener Assessments of Tracheoesophageal Speech Accuracy

Introduction: This study investigated the influence of stimulus composition for three speech intelligibility word lists and two scoring methods on the speech accuracy judgments of five tracheoesophageal (TE) speakers. This was achieved through phonemic comparisons across TE speakers’ productions of stimuli from the three intelligibility word lists, including the (1) Consonant Rhyme Test, (2) Northwestern Intelligibility Test, and (3) the Weiss and Basili list. Methodology: Fifteen normal-hearing young adults served as listeners; all listeners were trained in phonetic transcription (IPA), but none had previous exposure to any mode of postlaryngectomy alaryngeal speech. Speaker stimuli were presented to all listeners through headphones, and all stimuli were transcribed phonetically using an open-set response paradigm. Data were analyzed for individual speakers by stimulus list. Phonemic scoring was compared to a whole-word scoring method, and the types of errors observed were quantified by word list. Results: Individual speaker variability was noted, and its effect on the assessment of speech accuracy was identified. The phonemic scoring method was found to be a more sensitive measure of TE speech accuracy. The W&amp;B list yielded the lowest accuracy scores of the three lists. This finding may indicate its increased sensitivity and potential clinical value. Conclusions: Overall, this study supports the use of open-set, phonemic scoring methods when evaluating TE speaker intelligibility. Future research should aim to assess the specificity of assessment tools on a larger sample of TE speakers who vary in their speech proficiency.
