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.

Multicentric Study on Oncological Outcomes and Prognostic Factors of Open Partial Horizontal Laryngectomies.

Objective: In recent years, the number of open preservation surgeries for the treatment of laryngeal Cancer has increased. This surgery aims to maintain laryngeal function and ensure oncological radicality, thereby avoiding a total laryngectomy (TL) that could significantly impact the patient's quality of life. The purpose of this study was to assess the oncologic results of OPHL I and II and to identify prognostic factors that could impact patient survival and local failure rates. Methods: This study was conducted on 182 patients with laryngeal squamous cell carcinoma treated with OPHLs between 2005 and 2015. The survival rates of a group of patients treated with TL between 2004 and 2014 were taken into consideration to compare survival outcomes. Results: The disease-specific survival in pT2 and pT3 tumors in relation to the type of surgery showed no statistically significant difference between OPHLs and TL (P = .54 and P = .63, respectively). The 5-year T-recurrence-free survival showed that pT4 tumors, perineural/vascular positive invasion, and OPHL IIb + ARY-treated tumors were associated with a higher risk of tumor recurrence (P < .0001, P = .0005 and P = .016 respectively). Conclusions: OPHLs represent an excellent alternative to TL considering the characteristics of the tumor and the general conditions of the patient.

CD44, PDL1, and ATG7 Expression in Laryngeal Squamous Cell Carcinomas with Tissue Microarray (TMA) Technique: Evaluation of the Potential Prognostic and Predictive Roles.

We focus on the new prognostic and predictive factors CD44, PDL1, and ATG7 in our study of surgical samples of patients with laryngeal squamous cell carcinoma (LSCC) using tissue microarray (TMA). Thirty-nine previously untreated patients affected by laryngeal carcinoma who then underwent surgical treatment were considered in this retrospective study. All surgical specimens were sampled, embedded in paraffin blocks, and stained with hematoxylin and eosin. A representative sample of the tumor was chosen and transferred into a new block of paraffin, the recipient block, to perform immunohistochemical analysis with the primary antibodies anti-CD44, PD-L1, and ATG7. At follow-up, 5-year disease-free survival (DFS) for negative and positive tumors was determined as 85.71% and 36% for CD44, 60% and 33.33% for PDL1, and 58.06% and 37.50% for ATG7, respectively. Multivariate analysis revealed that CD44 expression is an independent predictive factor of low-grade tumors (p = 0.008), lymph node metastasis at the time of diagnosis, and AGT7 negativity. Thus, CD44 expression is a potential marker for more aggressive forms of laryngeal cancer.

Olfactory function in laryngectomised patients: tracheo-oesophageal versus oesophageal speech.

Objective: This study aimed to evaluate olfactory function in patients rehabilitated with oesophageal (ES) voice or tracheo-oesophageal (TES) prosthesis to further verify whether there were differences in smell alterations depending on voice rehabilitation modality. Methods: A total of 40 patients who had undergone total laryngectomy participated in the study. Speech rehabilitation was achieved through TES in 20 patients (Group A) or ES in 20 patients (Group B). Olfactory function was evaluated using the Sniffin' Sticks test. Results: At olfactory evaluation, in Group A, 4/20 patients (20%) were anosmic, whereas 16/20 patients (80%) were hyposmic; in Group B, 11/20 patients (55%) were anosmic whereas 9/20 patients (45%) were hyposmic. A significant difference (p = 0.04) was found at global objective evaluation. Conclusions: The study shows that the rehabilitation with TES contributes to maintaining a functioning, albeit limited, sense of smell.

Neurocognitive Performance Improvement after Obstructive Sleep Apnea Treatment: State of the Art.

BACKGROUND: Obstructive Sleep Apnea (OSA) syndrome is a respiratory sleep disorder characterized by partial or complete episodes of upper airway collapse with reduction or complete cessation of airflow. Although the connection remains debated, several mechanisms such as intermittent hypoxemia, sleep deprivation, hypercapnia disruption of the hypothalamic-pituitary-adrenal axis have been associated with poor neurocognitive performance. Different treatments have been proposed to treat OSAS patients as continuous positive airway pressure (CPAP), mandibular advancement devices (MAD), surgery; however, the effect on neurocognitive functions is still debated. This article presents the effect of OSAS treatments on neurocognitive performance by reviewing the literature. METHODS: We performed a comprehensive review of the English language over the past 20 years using the following keywords: neurocognitive performance and sleep apnea, neurocognitive improvement and CPAP, OSAS, and cognitive dysfunction. We included in the analysis papers that correlated OSA treatment with neurocognitive performance improvement. All validated tests used to measure different neurocognitive performance improvements were considered. RESULTS: Seventy papers reported neurocognitive Performance improvement in OSA patients after CPAP therapy. Eighty percent of studies found improved executive functions such as verbal fluency or working memory, with partial neural recovery at long-term follow-up. One article compared the effect of MAD, CPAP treatment on cognitive disorders, reporting better improvement of CPAP and MAD than placebo in cognitive function. CONCLUSIONS: CPAP treatment seems to improve cognitive defects associated with OSA. Limited studies have evaluated the effects of the other therapies on cognitive function.

The Role of Probiotics in Chronic Rhinosinusitis Treatment: An Update of the Current Literature.

Chronic rhinosinusitis (CRS) is a significant health problem. It affects 5-12% of the general population. The causes that underlie the onset of CRS are not yet well known. However, many factors may contribute to its onset, such as environmental factors and the host's general condition. Medical treatment mainly uses local corticosteroids, nasal irrigation, and antibiotics. In recent years, a new therapeutic approach that employs the use of probiotics emerged. Probiotics have been extensively studied as a therapy for dysbiosis and inflammatory pathologies of various parts of the body. We aimed to examine the studies in vivo and in vitro and clinicals reports in the existing literature to update probiotics' role in rhinosinusitis chronic medical treatment.

Role of P16 Expression in the Prognosis of Patients With Laryngeal Cancer: A Single Retrospective Analysis.

BACKGROUND: A possible oncogenic role of human papillomavirus (HPV) in head and neck cancers (mainly oropharynx tumors) has been suggested. This significant association has been considered true for oropharynx tumors; however, the association between HPV infection and laryngeal carcinomas is yet to be established. The aim of this study was to evaluate the relationship between p16 expression and long-term overall, disease-free, and disease-specific survival (OS, DF, and DSS, respectively) in patients surgically treated for laryngeal carcinoma. MATERIALS AND METHODS: Seventy-four previously untreated laryngeal carcinoma patients who underwent surgical treatment were considered for this retrospective study. The tissue specimens were processed for immunohistochemical p16 protein (surrogate HPV marker) detection. RESULTS: Survival analysis of the p16 expression of the primary tumor showed that the 5-year OS rates were 90% and 29.7% for the p16-positive and negative groups, respectively (P = .003). The 5-year DFS and DSS also differed between both groups (P < .001), whereas the 5-year DSS seemed to be related to tumor/lymph node classification and p16 expression. However, only p16 expression was identified as an independent prognostic factor associated with OS and DSS. CONCLUSIONS: Surgically treated p16-positive laryngeal cancer patients may represent a subset of patients with a better prognosis than their p16-negative counterparts.

Role of Clinical-Demographic Data in Survival Rates of Advanced Laryngeal Cancer.

Background and Objectives: Laryngeal cancer is one of the most common cancers in the upper aerodigestive tract, and tobacco and alcohol habits are the most relevant risk factors. The role of these risk factors in the incidence of laryngeal carcinomas is well known, yet only a few studies have been conducted on their role as risk factors of prognosis. The aim of the study was to assess the impact of clinical-demographic data on overall survival (OS), disease-free survival (DFS), and disease-specific survival (DSS) in patients with advanced-stage laryngeal cancer (Stage III-IV) who underwent total laryngectomy. Materials and Methods: This retrospective study was carried out on patients with Stage III-IV laryngeal squamous cell carcinoma treated with total laryngectomy between 2004 and 2014. For each patient, clinical and anamnestic data were collected and collated in a database, including alcohol and smoking habits. Results: Considering the variable age, family history, alcohol, grading, subsite, stage, pT stage, pN stage, and adjuvant therapy, no statistical significance was found for five-year OS. Smoking was the only variable that was statistically significant (p = 0.0043). A relevant difference was noted in the five-year DFS between pN-negative and pN-positive tumors (74.3% vs. 55.26%, respectively; p = 0.056), and a statistically significant difference was found between non- and ≤20 cigarettes/day smokers and heavy smokers (77.78% vs. 53.66%, respectively; p = 0.021). The five-year disease-specific survival rate was 68.83%, and a significant difference was detected for the smoking and pN stage variables. Heavy smokers (43.90% died vs. 16.67% of the non- and ≤20 cigarettes/day smokers; p = 0.0057) and pN-positive (42.1% died vs. 20.51% of the pN-negative patients; p = 0.042) patients had a worse prognosis. Conclusion: Smoking in our study was found to be an important independent risk factor for worse OS and DSS in patients with advanced laryngeal cancer.

Alteration of Smell and Taste in Asymptomatic and Symptomatic COVID-19 Patients in Sicily, Italy.

OBJECTIVES: Alteration of smell and taste has been reported in patients with coronavirus disease 2019 (COVID-19). The incidence and clinical-symptomatic manifestation of COVID-19 is different between northern and southern Italy. This study aims to evaluate the onset of alteration of smell and taste in asymptomatic and symptomatic patients in Sicily (extreme south of Italy). METHODS: This prospective cross-sectional study was performed on asymptomatic and symptomatic COVID-19 patients tested for severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) from May 1 to May 15, 2020. A questionnaire was used for evaluating the prevalence of smell and taste disorders in COVID-19 patients before performing nasopharyngeal swab. RESULTS: Of the total 292 patients, 242 (83.2%) were negative for SARS-CoV-2 and 50 were positive (16.8%). Twenty-six of the 50 (52%) SARS-CoV-2 positive patients reported smell/taste disorders. Twenty-eight of the 50 (57.1%) SARS-CoV-2 positive patients were hospitalized (group A), and 22 (42.9%) were nonhospitalized (group B). The mean age in group A and group B was 45.4 ± 13.7 years and 57.0 ± 15.0, respectively (P = .007). The symptoms reported by hospitalized patients were fever (71.4%), cough (64.2%), fatigue (82.1%), and dyspnea (100%), while in nonhospitalized patients, the most reported symptoms were sore throat (72.7%), rhinorrhea (77.2%), and altered smell (81.8%). Anosmia/hyposmia reported in group A and group B was 28.5% and 81.8%, respectively (P = .001). CONCLUSION: These preliminary results indicate that the majority of SARS-Cov-2 positive patients in southern Italy did not require hospitalization and presented with milder symptoms or no symptoms and the alterations in smell and taste occurred.

Early Glottic Cancer Treated by Transoral Laser Surgery Using Toluidine Blue for the Definition of the Surgical Margins: A Pilot Study.

Background and objectives: Transoral laser microsurgery (TLM) is widely accepted for its advantages, which consist of a brief hospital stay, rapid functional recovery, low management costs and the fact that it can be easily repeated in cases of recurrence. However, a high incidence of positive or narrow surgical margins has been reported in the literature, even if controversy still exists on the prognostic significance of positive resection margins. The aim of the study was to evaluate the utility of toluidine blue staining in defining the resection margins of early glottic cancer (T1a-T2) treated with TLM. Materials and Methods: This retrospective study was conducted on patients with early glottic cancer (T1a-T2) managed by TLM. A group of patients treated between 2010 and 2014 underwent toluidine blue staining (TB group) of the lesions before starting the cordectomy by TLM, and a group of patients treated by TLM between 2006 and 2009 was considered the control group. Results: A total of 44 subjects were included in this study: 41 were men, and 3 were women. The mean age was 58 ± 9.0 years (median 59.0, range 41-77). Twenty-three of the 44 patients were included in the TB group and 21 in the case control group. In the TB group, only the positivity of the deep margin was a predictor of local recurrence (p = 0.037), while in the control group, positive or close margins and the type of cordectomy were predictive factors of local recurrence (p = 0.049). Considering the TB group and control cases, the 5-year local recurrence-free survival was 95.6% and 80.9%, respectively (p = 0.14). Conclusions: From this first study, toluidine blue staining seems to be a useful modality to improve the rate of the negative resection margins of early glottic cancer (T1a-T2) treated by TLM.

Verbal performance of total laryngectomized patients rehabilitated with esophageal speech and tracheoesophageal speech: impacts on patient quality of life.

INTRODUCTION: Total laryngectomy has important psychophysical and social consequences for patients' quality of life because of the functional changes resulting from the removal of the larynx. Voice deprivation is perhaps the most relevant limiting factor in social relationships, increasing feelings of solitude and tending to drive individuals into social isolation. Multiple voice rehabilitation methods after total laryngectomy are available. This study aimed to determine the acoustic quality of the rehabilitated voice achieved with esophageal speech (ES) and tracheoesophageal speech (TES), and acoustic quality impacts on patients' perceptions of their quality of life. MATERIALS AND METHODS: The patient inclusion criterion was the completion of a speech rehabilitation course with ES or TES at least 6 months after total laryngectomy. The voice acoustic analysis was carried out automatically by using the Multidimensional Voice Program. The following parameters were extracted: fundamental frequency (F0), Jitter% (Jitt), Shimmer% (Shim), and noise-to-harmonic ratio (NHR). Subjective voice evaluation was performed by using the following questionnaires: Voice Handicap Index (VHI), Voice-related Quality of Life (V-RQOL), and Voice Performance Questionnaire (VPQ). RESULTS: The acoustic analysis showed a difference between ES and TES patients on all acoustic parameters; this difference was significant for F0 (133.09±2.4 and 119±3.3, respectively; p<0.001), NHR (0.43±0.21 and 0.31±0.14, respectively; p=0.02), and maximum phonation time (2.02±038 s and 10.64±0.28 s, respectively; p=0.01. Regarding patient-related outcomes, TES correlated with better total scores compared with ES; however, the differences in the total scores on the VHI (p=0.09), V-RQOL (p=0.39), and VPQ (p=0.52) were not statistically significant. CONCLUSION: The rehabilitation of laryngectomized patients must be addressed by a multidisciplinary team that considers the personalities, personal needs, and relational conditions of individual patients in order to determine and apply the phonatory rehabilitation method most suitable for achieving a better quality of life.

Impact of the anterior commissure involvement on the survival of early glottic cancer treated with cricohyoidoepiglottopexy: a retrospective study.

BACKGROUND: Laryngeal early glottic tumors can benefit from different treatment modalities, including transoral laser microsurgery, open partial horizontal laryngectomy (OPHL), and radiotherapy. However, the treatment of early glottic tumors with the involvement of the anterior commissure remains controversial. The studies about the role of anterior commissure involvement in oncologic outcomes in patients with early glottic cancer treated with supracricoid laryngectomy (SCL) are very few. For this reason, we conducted a retrospective study to evaluate local recurrence-free survival and specific survival in patients with and without involvement of the anterior commissure who underwent SCL with cricohyoidoepiglottopexy. METHODS: This retrospective study has been carried out on patients with T1b-T2 glottic squamous cell carcinoma submitted to SCL with cricohyoidoepiglottopexy. The patients' demographic and clinical data were collected, and the histological findings of the surgical specimens were reviewed to identify patients who had involvement of the anterior commissure. RESULTS: A total of 72 patients were included in the study; two of them were female and 70 were male. The mean age at diagnosis was 61.5±8.0 SD years. In 26 of the 72 (36.2%) patients, anterior commissure was not pathologically involved (group A), while in 46 (63.8%) patients, it was involved (group B). The 5-year local recurrence-free survival rate was 96.1% and 93.48% in groups A and B, respectively, P=0.09. The 5-year disease-specific survival rate was 92.31% and 95.65% in groups A and B, respectively, P=0.057. CONCLUSION: SCL with cricohyoidoepiglottopexy seems to be an adequate treatment modality, even for T1b-T2 glottic tumors with anterior commissure involvement.

Ectopic lingual thyroid with vascular anomalies.

BACKGROUND: Lingual thyroid represents 90% of ectopic thyroid tissue localizations. The first case was described by Hickman in 1869. An ectopic thyroid is often asymptomatic, but pathological or physiological conditions inducing hyperproduction of thyroid-stimulating hormone can lead an ectopic thyroid to become symptomatic. Treatment of the symptomatic ectopic thyroid can be medical, with hormone-suppressing therapy, or surgical. CASE PRESENTATION: A 17-year-old female presented to our outpatient clinic complaining of a sensation of a lump in her throat. Ear, nose, and throat (ENT) examination identified a swelling of the base of the tongue in the glossoepiglottic area. Thyroid scintigraphy showed a single contrast enhancement in the sublingual region, instead of in the normal anatomical position of the thyroid. She was treated surgically after failed hormone-suppressing therapy. An arteriography performed before the surgery showed vascular anomalies and was useful in surgical planning. CONCLUSION: Recognition of vascular anomalies in an ectopic thyroid is fundamental before surgical planning, therefore, accurate radiological study of the vasculature should always be planned before surgical treatment of this disease.

Quality of voice evaluation in patients treated by supracricoid laryngectomy and modified supracricoid laryngectomy.

OBJECTIVE: To compare quality of voice in patients treated by supracricoid laryngectomy and patients treated by modified supracricoid laryngectomy using the sternohyoid muscle for neoglottis reconstruction. STUDY DESIGN: Case series. Setting. Teaching hospital. SUBJECTS AND METHODS: This study was performed between 2004 and 2008 on 28 consecutive patients affected by T1b-T2 laryngeal carcinoma. Eleven patients were treated by supracricoid laryngectomy, and 17 patients were treated by modified supracricoid laryngectomy. For each patient, postoperative parameters such as decannulation time, nasogastric feeding tube, and length of hospitalization were noted. Vocal function, Voice Handicap Index scores, and perceptual voice analysis scores on intelligibility, noise, fluency, and voice scale were evaluated. RESULTS: The postoperative course of the patients treated by modified supracricoid laryngectomy was similar to patients treated by supracricoid laryngectomy. No delay in the length of hospitalization was detected in patients undergoing surgery with the new technique. A significant difference was detected in the nasogastric tube removal time and decannulation time. The data from intelligibility, noise, fluency, and voice scale analyses revealed a better quality of voice in patients treated by modified supracricoid partial laryngectomy with a significant difference in intelligibility, fluency, and voicing. The Voice Handicap Index mean value of physical, functional, and emotional subscales confirmed patients' perceptions of a minor voice handicap in patients treated by modified supracricoid laryngectomy, with a significant difference on the physical subscale. CONCLUSION: Modified supracricoid laryngectomy seems to be a good way to improve quality of voice and quality of life in patients with early laryngeal cancer.
