Abstract
OBJECTIVE Therapy and vocal rehabilitation in laryngeal cancer impact patients' quality of life. The objective of this study was to evaluate the evolution of the quality of life of patients with laryngeal cancer submitted to total laryngectomy and using electrolarynx. METHODS This is an observational study with a cross-sectional design and a quantitative approach. It was conducted between April 2022 and January 2023 in a Brazilian cancer hospital. For data collection, a quality of life questionnaire, validated for patients with head and neck cancer at the University of Washington, was applied in two phases: from 7 days after total laryngectomy and, subsequently, from 70 days after surgery using electronic larynx for at least 60 days. The inclusion criteria were patients undergoing total laryngectomy included on the Aldenora Bello Cancer Hospital's election list to receive the electronic larynx. Patients who did not sign the informed consent form were not included. RESULTS The sample consisted of 31 patients, of which approximately 84% were men and approximately 93% at the age of 50 years or older. When comparing the phases, it is possible to observe that the item speech had the greatest progress, while chewing had the least. Only the item recreation, swallowing, taste, and saliva did not show any statistical significance. The score for the general quality of life questions increased. CONCLUSION Electronic larynx is a viable and useful method of voice rehabilitation. Our data suggest that the use of the electrolarynx as a postlaryngectomy method of verbal communication is responsible for positive effects on patients' quality of life.

Development and Content Validity of a Novel Patient-Reported Outcome Measure for Total Laryngectomy: The LARY-Q. J Voice 2023:S0892-1997(23)00132-7. [PMID: 37156685 DOI: 10.1016/j.jvoice.2023.04.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2023] [Accepted: 04/12/2023] [Indexed: 05/10/2023]
Abstract
OBJECTIVES To develop a patient-reported outcomes measure (PROM) for total laryngectomy. STUDY DESIGN Qualitative interviews with a purposive sample of patients with total laryngectomy, followed by cognitive debriefing interviews with patients and expert feedback. METHODS Concept elicitation was performed using in-depth qualitative interviews with a purposive sample of patients who had undergone total laryngectomy. Patients were recruited from head and neck surgery and speech-language pathology clinics as well as via laryngectomy support groups. Interviews were conducted, recorded, transcribed, and coded, resulting in a conceptual framework and item pool. Using the item pool, preliminary scales were drafted. The scales were revised iteratively over 5 rounds using feedback from cognitive interviews with patients and multi-institutional and multi-disciplinary expert feedback. RESULTS A total of 15 patients with total laryngectomy (mean age 68 years, range 57-79) were interviewed resulting in 1555 codes. The codes were used to form a conceptual framework grouped into top-level domains of stoma, function, health-related quality of life, devices, and experience of care. Items were used to form 15 preliminary scales that were revised over five rounds of cognitive debriefing interviews (n = 9 patients) and expert feedback (n = 17 experts). The field-test version of the LARY-Q has 18 scales and 277 items in total. CONCLUSIONS The LARY-Q is a novel PROM designed to assess outcomes associated with total laryngectomy. The next step involves a field test study with a heterogenous sample of patients to assess the psychometric properties of the LARY-Q and perform item reduction.

Subjective Perception and Psychoacoustic Aspects of the Laryngectomee Voice: The Impact on Quality of Life. J Pers Med 2023; 13:jpm13030570. [PMID: 36983751 PMCID: PMC10057772 DOI: 10.3390/jpm13030570] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2022] [Revised: 02/17/2023] [Accepted: 03/21/2023] [Indexed: 03/29/2023] Open
Abstract
Purpose: A retrospective study is presented to correlate the inter-judge consistency for the different psycho-perceptual parameters of the recently proposed Impression Noise Fluency Voicing (INFVo) perceptual rating scale for substitution voices, and the vocal function as perceived by the patient. Methods: The scale Voice-Related Quality of Life (V-RQoL) and the Self Evaluation of Communication Experiences After Laryngectomy scale (SECEL)—a self-evaluation questionnaire of communicative experience after laryngectomy surgery—were administered to 89 total laryngectomees, subdivided in four groups depending on their type of alaryngeal voice (i.e., tracheoesophageal and esophageal speakers, electro larynx users, voiceless patients), in order to evaluate the impact of the impairment of the phonatory function on the quality of life. Results: No significant differences exist among the various groups on their perception of QoL using subjective questionnaires, whereas the INFVo scale has proven to be a useful tool for the description and analysis of the psychoacoustic characteristics of the vocal signal and a reliable instrument to correctly classify the patients. It is also notable that the judgement of the patients on their own voice and those of the referees are highly significant. Conclusion: Although speech rehabilitation for the acquisition of a substitution voice offers a new way of communication for the laryngectomized patients, nonetheless, their QoL is not significantly related to the type of substitution voice. Therefore, improving the patient’s adaptation to the new phonatory condition is mandatory.

Abstract
Purpose Biofilms on voice prostheses are important factors shortening their service life. Sodium selenite has been used to prevent and treat various diseases. Whether sodium selenite can inhibit and remove mature biofilms on voice prostheses is still unknown. Methods To verify the effects of sodium selenite on mature mixed-bacteria biofilms (Staphylococcus aureus, Candida albicans, and Streptococcus faecalis) on voice prostheses, we used quantitative and qualitative methods, eg, real-time fluorescence quantitative PCR, crystal violet staining, 2,3-bis(2-methoxy-4-nitro-5-sulfophenyl)-2H-tetrazolium-5-carboxanilide) (XTT) reduction assays, and scanning electron microscopy, to measure the effects of sodium selenite on the number of bacterial colonies, biofilm formation ability, metabolic activity, and ultrastructure in a model of mature mixed-bacteria biofilms on voice prostheses and validated the effects in vitro on mature biofilms on voice prostheses from patients. Results When exploring the possible mechanism of biofilm inhibition and removal by sodium selenite, we found that it significantly inhibited and removed biofilms on voice prostheses and effectively destroyed the spatial structure of the biofilms. The inhibition and removal effects became more significant with increasing sodium selenite concentrations. Conclusion We demonstrated that sodium selenite can inhibit and remove biofilms of mature mixed strains on voice prostheses, providing a novel basis for treating patients' voice prosthesis biofilms.

Abstract
I wish to thank the Semon Committee for inviting me to deliver the 2020 Semon lecture. This is a very special honour, as is evidenced by the list of distinguished lecturers dating back to the inaugural lecture delivered at University College London in 1913. I am not the first South African to deliver the Semon lecture, having been preceded by my previous chairman Sean Sellars in 1993, and by Jack Gluckman in 2001, who was South African raised and educated and who subsequently became the chairman of otolaryngology in Cincinnati, USA.

Abstract
OBJECTIVE To assess long-term functional and quality of life (QoL) outcomes and their predictive factors in laryngectomized patients after successful voice restoration using tracheoesophageal prostheses (TEP). METHODS This cross-sectional study was conducted in alive and disease-free patients at least 1 year after total laryngectomy ± partial pharyngectomy. Patients completed the European Organization for Research and Treatment of Cancer (EORTC) Core (QLQ-C30) and Head and Neck Cancer (QLQ-H&N35) QoL questionnaires, the Voice Handicap Index (VHI-10) questionnaire and the Hospital Anxiety and Depression Scale (HADS). The level of dysphagia was evaluated using the Dysphagia Handicap Index (DHI) and the Dysphagia Outcomes and Severity Scale (DOSS). Predictive factors of these clinical outcomes were determined in univariate and multivariate analysis. RESULTS A total of 48 patients were included in this study. Long-term QoL and functioning scales scores were all superior to 70%. Main persistent symptoms were fatigue, dyspnea, senses, speech and coughing problems. A DOSS score ≥6, indicating normal/subnormal swallowing function, and a VHI-10 score ≤20, representing light to medium voice disorders, were found in at least 75% of patients. An anxiodepressive disorder (HADS global score ≥ 15) was reported by 15 (31%) patients and represented the main predictor of QoL and voice outcomes. A strong correlation was found between VHI-10 and global QoL scores. CONCLUSIONS After successful voice restoration, laryngectomized patients achieved satisfactory QoL and functional outcomes. Psychological distress was the main determinant of long-term QoL and is therefore of critical importance in the multidisciplinary management of laryngectomized patients.

Abstract
OBJECTIVE Treatment of advanced laryngeal and hypopharyngeal cancer has shifted from total laryngectomy (TL) toward laryngeal-preserving therapies due to a general perception that TL has a significantly negative impact on the individual's life. However, whether the physical impairments related to TL translate to a reduced health-related quality of life (HRQoL) has not yet been determined. Therefore, the objective of this systematic review was to determine how HRQoL is affected following TL. METHODS Systematic searches were conducted in PubMed, Embase, and Cochrane. Inclusion criteria were original studies describing quality of life following TL after larynx/hypopharynx cancer using a formally developed patient-reported questionnaire. Study quality assessment was carried out with the tool developed by the National Heart, Lung, and Blood Institute. RESULTS Forty-six studies using 12 different questionnaires were included. The majority were cross-sectional (85%), and study quality was rated poor in 30%, fair in 30%, and good in 39% of studies. When comparing results from the four most frequently used questionnaires with normative data, we found that in more than 60% of studies, differences to the reference population were of clinical importance, with only few exceptions. CONCLUSIONS In general, we found that people who received TL have a worse HRQoL than the male normative reference population. However, even though TL patients experience a clinically important difference in many domains when compared with normative data, their burden of symptoms is generally mild. The current review also makes it evident that despite the relatively large number of studies conducted, the strength of evidence remains weak. Laryngoscope, 131:820-831, 2021.

Abstract
BACKGROUND/AIMS When considering the quality of life of patients who undergo total laryngectomy, constipation problems are often overlooked. This study aims to determine whether surgical or concurrent chemoradiotherapy treatments matter in the development of functional constipation in patients with advanced-stage laryngeal cancer. MATERIALS AND METHODS Patients without presurgical constipation (according to Rome IV) who were treated with either surgery (n=30) or chemoradiation (n=25) were evaluated for constipation development. Interim evaluation and recommendations were made on the 3rd month. On the 3rd and 6th months, the frequency of constipation between groups was compared using the Rome IV criteria and European Organization for Research and Treatment of Cancer Quality of Life Scale-C30 constipation symptom score. RESULTS On the 3rd month, the frequency of constipation was higher in the surgery group than in the chemoradiation group (76.7% vs. 28%, p<0.001). On the 6th month, although still higher, the frequency of constipation decreased following the recommendations in laryngectomized patients (56.7% vs. 36%, p=0.17). C30 Constipation "yes/no" inquiry failed to detect 11 (36.6%) and 8 (26.6%) laryngectomized patients with constipation on the 3rd and 6th months, respectively. CONCLUSION Constipation is more frequent and develops in the early period of postlaryngectomy. Patients seem to benefit from additional special rehabilitation recommendations. Constipation-prone laryngectomized patients should be screened with the Rome IV criteria, which effectively detect constipation.

Abstract
OBJECTIVE The aim of this study was to correlate several instruments currently used for the assessment of the quality of life of patients who underwent total laryngectomy and speech rehabilitation. METHODS A cross-sectional, observational study was conducted with 38 patients after total laryngectomy and speech therapy aiming to develop oesophageal speech. The patients were divided into the following two groups (19 participants each): speakers and non-speakers. The quality of life instruments used were as follows: visual analogue scale (VAS); Voice Handicap Index (VHI); Voice-Related Quality of Life (V-RQOL); Functional Assessment of Cancer Therapy - Head & Neck (FACT-H&N); European Organisation for Research and Treatment of Cancer Core Quality of Life Questionnaire (EORTC QLQ-C30); European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Head and Neck (EORTC QLQ-H&N35); and University of Washington Quality of Life (UW-QOL). RESULTS The V-RQOL global health domain exhibited a strong correlation with the VHI. The EORTC QLQ-C30 exhibited a moderate to strong correlation with the EORTC QLQ-H&N35 functional domain in both groups. The EORTC QLQ-C30 functional domain exhibited a strong to moderate correlation with all other instruments in both groups. The UW-QOL exhibited a moderate to strong correlation with the VHI and EORTC QLQ-C30 in both groups. CONCLUSION The EORTC QLQ-C30, EORTC QLQ-H&N35 and UW-QOL were the instruments that most correlated with the remaining instruments, indicating that any of the three can be used to assess the quality of life of the target population regardless of oesophageal voice development.
