Abstract
BACKGROUND Lifetime elongation of the silicone voice rubber prostheses by inhibition of biofilm formation is a primary objective in voice restoration of laryngectomized patients. This systematic review sought to explore the existing strategies in this direction. MATERIALS We conducted a systematic search of both in vitro and in vivo literature published in PubMed, Scopus, and Cochrane Central Register of Controlled Trials, until December 31, 2022, for published and unpublished trials assessing the strategies for inhibiting biofilm formation on silicone rubber voice prostheses, and appraised quality assessment with the modified Consolidated Standards of Reporting Trials tool. We analyzed the infection prevention capacity of the included antibacterial and antifungal agents. RESULTS The qualitative synthesis showed that both surface modification methods and prophylactic treatment of silicone rubber voice prostheses present adequate antibiofilm activity. Of note, the majority of the suggested prosthetic surfaces were not chronically exposed to both human fluids and biofilm-forming microorganisms. CONCLUSION Various experimental methods provide promising antibiofilm activity and, thus, possible lifespan elongation of silicone rubber voice prostheses.

Abstract
Early failure of silicone voice prostheses resulting from fungal colonization and biofilm formation poses a major concern in modern ear nose throat surgery. Therefore, developing new infection prevention techniques to prolong those implants' survivorship is crucial. We designed an in vitro laboratory study to include nanomaterial-enhanced polymer coating with a plasma spraying technique against Candida albicans growth to address this issue. The anti-biofilm effects of high- and low-dose Al2O3 nanowire and TiO2 nanoparticle coatings were studied either alone or in conjunction with each other using checkerboard testing. It was demonstrated that both nanomaterials were capable of preventing fungal biofilm formation regardless of the anti-fungal agent concentration (median absorbance for high-dose Al2O3-enhanced polymer coating was 0.176 [IQR = 0.207] versus control absorbance of 0.805 [IQR = 0.381], p = 0.003 [98% biofilm reduction]; median absorbance for high-dose TiO2-enhanced polymer coating was 0.186 [IQR = 0.024] versus control absorbance of 0.766 [IQR = 0.458], p < 0.001 [93% biofilm reduction]). Furthermore, synergy was revealed when the Bliss model was applied. According to the findings of this work, it seems that simultaneous consideration of Al2O3 and TiO2 could further increase the existing antibiofilm potential of these nanomaterials and decrease the likelihood of localized toxicity.

Abstract
Introduction The loss of voice after total laryngectomy is one of the main impairments in personal and social life. In order to prevent potential psycho-social consequences in the patient and his family, the restoration of phonatory function is the main objective of post-laryngectomy rehabilitation. The aim of this study was to assess quality of life in patients who received prosthetic voice after total laryngectomy. Materials and Methods Over a one-year period, 51 patients with voice prostheses after total laryngectomy were recruited. 32 patients (62.74%) were administered radiation therapy and 9 patients (17.64%) underwent to surgical reconstruction with flaps. Each patient was administered the VHI-10 and V-RQOL self-assessment questionnaires. Results The study showed that vocal restoration with voice prosthesis allows patients to recover a significant degree of quality of life after total laryngectomy. The average score on the V-RQOL questionnaire was 75.9 and on the VHI-10 questionnaire was 13.5. It has not been shown a statistically significant correlation between quality of life after tracheoesophageal prosthesis and radiation therapy, chemotherapy or reconstruction flaps. Younger patients showed, on average, a higher score at V-RQOL. These results allow to state that, after prosthetic rehabilitation, at least 75% of patients experienced an increase in quality of life. Moreover, the prosthetic technique (primary vs secondary) does not affect the long-term outcome and radiotherapy, chemotherapy or reconstruction flaps are not absolute contraindications to rehabilitation with voice prosthesis. Conclusion After total laryngectomy, rehabilitation with tracheoesophageal prosthesis is a satisfactory choice to restore the patient's ability to communicate verbally.

Abstract
OBJECTIVE(S) To evaluate complication rate and abandonment rate after tracheoesophageal puncture and to assess factors associated with these outcome measures. METHODS Retrospective review of laryngectomy patients seen at a single academic institution between 1/1/2003 and 12/1/2018. Charts reviewed for demographics, medical comorbidities, tumor characteristics, surgical data, adjuvant treatment history, and complications related to laryngectomy or tracheoesophageal puncture. Complications were divided into minor and major. RESULTS A total of 293 laryngectomees met inclusion criteria. Of these, 69 patients (23.5%) underwent tracheoesophageal puncture. Average follow up was 64.6 months (SD 58.3). Overall laryngectomy complication rate was 43.3%. Overall tracheoesophageal puncture complication rate was 73.9%, with 39.1% of patients having major complications and 34.8% having minor complications only. Total abandonment rate for tracheoesophageal puncture was 34.8%. No associations were seen between tracheoesophageal puncture complication or abandonment rates based on age, gender, race, or insurance status. An increased rate of laryngectomy complications was seen after primary tracheoesophageal puncture (76.5% vs 41.3%, P = .005). CONCLUSION Tracheoesophageal puncture outcomes were similar in patients with varied demographic, medical, and treatment backgrounds. When considering timing, our findings suggest that patients should be counseled on the possibility of increased complication risk after primary tracheoesophageal puncture. In those in whom the surgeon already has concerns about wound healing, it may be prudent to avoid primary tracheoesophageal puncture. The relatively high abandonment rate emphasizes the value of this measure of tracheoesophageal puncture outcome and highlights the need for appropriate patient counseling and prospective studies assessing the decision to abandon.

Abstract
Total laryngectomy is the standard of care for advanced laryngeal/hypopharyngeal cancer. Effective voice rehabilitation is mandatory and tracheo-oesophageal speech (TES) has progressively gained approval. In 2011, we evaluated quality of life (QoL) and satisfaction after TES rehabilitation, demonstrating its efficacy in highly motivated subjects. The aim of the present study was to investigate whether those results are maintained over time within the same selected cohort. 15 of 24 patients were left with a minimum 12 year-follow up after voice prosthesis (VP) implantation. Short Form 36-Item Health Survey (SF-36) for QoL assessment and a study-specific structured questionnaire for evaluation of TES-related satisfaction were employed. The 9/24 patients who dropped out from the follow-up were excluded from the original count and the former results were recalculated. A control group of subjects with minor ENT diseases was used for SF-36 analysis. Many SF-36 items (RP, BP, SF, RE) significantly improved over time, approaching the results of the control group. VP duration also increased (6.3 ± 3.1 against 3.0 ± 1.8 months). TES-related satisfaction items did not change in a statistically significant way. Three patients (20.0%) would not have chosen the same kind of voice restoration: these subjects are those more distant from our institution (230 km and 462 km, respectively, against a mean distance of 15.4 ± 13.8 km for other patients). With the present work, we highlight how the striking results of TES can not only be maintained over time (i.e. TES-related satisfaction), but also substantially improve (i.e. QoL). An integrated, widespread network of centres for VP management is needed to optimise patient follow-up and allow studies on larger series.

Abstract
OBJECTIVES Veterans have an increased risk of laryngeal cancer, yet their oncologic and functional outcomes remain understudied. We sought to determine the longitudinal impact of tracheoesophageal puncture and voice prosthesis on quality-of-life measures in veterans following total laryngectomy (TL). METHODS We performed a cross-sectional analysis of TL patients (n = 68) treated at the Michael E. DeBakey Veterans Affairs Medical Center using the Voice Handicap Index (VHI), MD Anderson Dysphagia Index (MDADI), and University of Washington Quality of Life Index (UW-QOL). RESULTS Using tracheoesophageal (TE) speech was associated with significantly better VHI, MDADI, and UW-QOL scores compared to other forms of communication. The association between TE speech use on VHI, MDADI, and UQ-QOL persisted even when the analysis was limited to patients with >5-year follow-up and was maintained on multivariate analysis that accounted for a history of radiation and laryngectomy for recurrent laryngeal cancer. CONCLUSIONS Using tracheoesophageal speech after total laryngectomy is associated with durable improvements in quality of life and functional outcomes in veterans. Tracheoesophageal voice restoration should be attempted whenever technically feasible in patients that meet the complex psychosocial and physical requirements to appropriately utilize TE speech.

Abstract
BACKGROUND Health-related quality of life (HRQL) and voice handicap index (VHI) of laryngectomies seem to be relevant regarding voice rehabilitation. The aim of this study is to assess the impact on HRQL and VHI of laryngectomies, following voice rehabilitation. MATERIALS AND METHODS A retrospective study done at the Ear, Nose, and Throat Department of the Emergency County Hospital. Sixty-five laryngectomees were included in this study, of which 62 of them underwent voice rehabilitation. Voice handicap and QOL were assessed using the QOL questionnaires developed by the European Organisation for Research and Treatment of Cancer (EORTC); variables used were functional scales (physical, role, cognitive, emotional, and social), symptom scales (fatigue, pain, and nausea and vomiting), global QOL scale (pain, swallowing, senses, speech, social eating, social contact, and sexuality), and the functional, physical, and emotional aspects of the voice handicap (one-way ANOVA test). RESULTS The mean age of the patients was 59.22 (standard deviation = 9.00) years. A total of 26 (40%) patients had moderate VHI (between 31 and 60) and 39 (60%) patients had severe VHI (higher than 61). Results of the HRQL questionnaires showed that patients who underwent speech therapy obtained better scores in most scales (P = 0.000). Patients with esophageal voice had a high score for functional scales compared with or without other voice rehabilitation methods (P = 0.07), and the VHI score for transesophageal prosthesis was improved after an adjustment period. The global health status and VHI scores showed a statistically significant correlation between speaker groups. CONCLUSION The EORTC and the VHI questionnaires offer more information regarding life after laryngectomy.

Abstract
OBJECTIVE This study investigated the relationship between psychological well-being and different voice rehabilitation methods in total laryngectomy patients. METHODS The study enrolled 96 patients who underwent total laryngectomy. The patients were divided into three groups according to the voice rehabilitation method used: esophageal speech (24 patients); a tracheoesophageal fistula and Provox 2 voice prosthesis (57 patients); or an electrolarynx (15 patients). The participants were asked to complete the Turkish version of the Voice Handicap Index-10 (VHI-10) to assess voice problems. They were also asked to complete the Turkish version of the Perceived Stress Scale (PSS), and the Hospital Anxiety and Depression Scale (HADS). The test scores of the three groups were compared statistically. RESULTS Patients who used esophageal speech had a mean VHI-10 score of 10.25 ± 3.22 versus 19.42 ± 5.56 and 17.60 ± 1.92 for the tracheoesophageal fistula and Provox 2 and electrolarynx groups respectively, reflecting better perception of their voice. They also had a PSS score of 11.38 ± 3.92, indicating that they felt less stressed in comparison with the tracheoesophageal fistula and Provox 2 and electrolarynx groups, which scored 18.84 ± 5.50 and 16.20 ± 3.49 respectively. The HADS scores of the groups were not different, indicating that the patients' anxiety and depression status did not vary. CONCLUSION Patients who used esophageal speech perceived less stress and were less handicapped by their voice.

Abstract
Mixed biofilms with fungi and bacteria are the leading cause for the failure of medical silicone devices, such as voice prostheses in laryngectomy. In this study, we determined the effect of carboxymethyl chitosan (CM-chitosan) on mixed biofilm formation of fungi and bacteria on silicone which is widely used for construction of medical devices. Mixed biofilm formations were inhibited 72.87% by CM-chitosan. Furthermore, CM-chitosan significantly decreased the metabolic activity of the biofilms using 2, 3-bis (2-methoxy-4-nitro-5-sulfo-phenyl)-2H-tetrazolium-5 carboxanilide (XTT) reduction assay. The examination using confocal laser scanning microscopy and scanning electron microscope confirmed that CM-chitosan inhibited the mixed biofilm and damaged the cells. Effects of CM-chitosan on different stages of biofilms were also evaluated. CM-chitosan inhibited the adhesion of fungi and bacteria with an efficiency of >90%. It prevented biofilm formation at efficiencies of 69.86%, 50.88% and 46.58% when CM-chitosan was added at 90min, 12h and 24h after biofilm initiation, respectively. Moreover, CM-chitosan inhibited Candida yeast-to-hyphal transition. CM-chitosan was not only able to inhibit the metabolic activity of biofilms, but also active upon the establishment and development of biofilm. Therefore, CM-chitosan may serve as a possible antibiofilm agent to limit biofilm formation on voice prostheses.

Abstract
OBJECTIVE To investigate the therapeutic effect of surgery, radiotherapy and photodynamic therapy on early glottic carcinoma and prognostic factors. METHODS Retrospective analysis of 202 cases with early glottic carcinoma (Tis-T2N0M0) underwent surgery (n=152), radiotherapy (n=20) and PDT (n=30) from 2000 to 2013 The KPS score, the disease-free survival (DFS), overall survival (OS), local control (LC), larynx preservation rate, laryngeal function were evaluated. The methods of χ (2)test or Fisher's exact probability method, Kaplan Meier method, log-rank test of Kaplan-Meier method, Cox proportional hazards model were used to analyze the data. RESULTS There was no statistical significance in OS, DFS and LC among the three groups. The laryngeal function preservation rate of RT group, PDT group and Surgery group were 90%, 86.7% and 65.1% respectively, with the former two groups significantly superior to Surgery group. While there is no statistical significance between RT group and PDT group. Single factor analysis showed that KPS score before treatment, vocal fold mobility limitation and differentiation degree could have an effect on prognosis. Multivariate regression analyses indicated that anterior commissure invasion, T stage and KPS score before treatment were independent adverse prognostic factors for OS. T stage and differentiation degree were adverse prognostic factors for DFS. T stage was also an adverse factor of LC. Thirty-three cases experienced local recurrence or cervical lymph node metastasis. Three groups showed no statistical difference in local recurrence or lymph node metastasis, with twenty-two cases in Surgery group, four in RT group and seven in PDT group. CONCLUSIONS The therapeutic effect was approximate in surgery group, radiotherapy group and photodynamic group, and all three treatment regimens achieved good clinical effect. Radiotherapy and photodynamic therapy may be the first or very important treatment on early stage glottic squamous cell cancer (Tis∼T2N0M0). However only 6 patients underwent PDT for T2 disease, making definitive treatment conclusions for this subgroup unclear.

Abstract
OBJECTIVES Loss of speech following tracheostomy and laryngectomy severely limits communication to simple gestures and facial expressions that are largely ineffective. To facilitate communication in these patients, we seek to develop a low-cost, noninvasive, portable, and simple visual speech recognition program (VSRP) to convert articulatory facial movements into speech. METHODS A Microsoft Kinect-based VSRP was developed to capture spatial coordinates of lip movements and translate them into speech. The articulatory speech movements associated with 12 sentences were used to train an artificial neural network classifier. The accuracy of the classifier was then evaluated on a separate, previously unseen set of articulatory speech movements. RESULTS The VSRP was successfully implemented and tested in 5 subjects. It achieved an accuracy rate of 77.2% (65.0%-87.6% for the 5 speakers) on a 12-sentence data set. The mean time to classify an individual sentence was 2.03 milliseconds (1.91-2.16). CONCLUSION We have demonstrated the feasibility of a low-cost, noninvasive, portable VSRP based on Kinect to accurately predict speech from articulation movements in clinically trivial time. This VSRP could be used as a novel communication device for aphonic patients.

Abstract
Health-related quality of life (HRQoL) focuses on 4 core domains: physical and psychological function, social interaction, disease, and treatment-related symptoms, and is a key outcome in patients with cancer of the head and neck. We reviewed papers published between 2006 and 2013 that used validated questionnaires to report functional outcome in this group. A total of 572 papers were identified and 118 of them concerned function. Specific outcomes included anxiety, chewing, maxillectomy, mucositis, pain, shoulder function, and trismus. The specific functions most often identified were xerostomia, speech or voice, and swallowing or dysphagia. A considerable body of evidence has now accumulated on HRQoL and functional outomes although the precise role of HRQoL during the planning of treatment remains controversial. Over time, the emphasis of the studies included has tended to move away from the reporting of outcomes in general to more hypothesis-driven and group-specific work.
