Late-onset laryngeal paralysis: Owner perception of quality of life and cause of death.

BACKGROUND: Late-onset laryngeal paralysis (LoLP) is an idiopathic disease of older dogs, and is common in the Labrador Retriever. Owner perspective of how LoLP affects their pet's quality of life (QOL), the degree to which LoLP is perceived to be a life-limiting disease, and how a glottic opening procedure affects these perceptions is not known. OBJECTIVES: (a) To determine owner's perception of late-onset laryngeal paralysis (LoLP) with respect to their dog's QOL; (b) To determine whether LoLP is considered by owners to be a life-limiting disease; (c) To evaluate whether a glottic opening procedure altered QOL and perceived cause of death in affected dogs. METHODS: Owners of Labrador Retrievers with LoLP completed a questionnaire. Questions were asked pertaining to a dog's LoLP, including clinical progression and perception of cause of death, and whether a glottic opening procedure was undertaken. Owners also completed a pet-owner administered QOL survey. RESULTS: Seventy-six owners participated. Overall, 94% of owners felt their dog's LoLP affected QOL, and 47% of owners felt LoLP was a large contributing factor in their dog's death. Dogs that underwent a glottic opening procedure were reported to have a better QOL, and the contribution of LoLP towards their death was less than dogs that did not have surgery. CONCLUSION: Owners of Labrador Retrievers with LoLP perceive LoLP to be a life-limiting disease that negatively impacts their dog's QOL. Arytenoid lateralization surgery had a positive impact on QOL in affected dogs.

Impaired vocal cord mobility in T2N0 glottic carcinoma: Suboptimal local control with Radiation alone.

BACKGROUND: T2 glottic cancer with impaired vocal cord mobility (T2b) is known to have higher local failure rates when compared with T2 cancers without impaired cord mobility (T2a) treated with radiotherapy (RT) alone. METHODS: In this retrospective review, we identified and compared the local control rates of 3 groups: T2aN0 treated with RT; T2bN0 treated with RT; and T2b-3N0-2 treated with chemoradiotherapy (CRT). RESULTS: The 3-year local control rate was 95.1% for T2aN0, 73.2% for T2bN0 treated with RT, and 91.5% for the CRT group (p = .01). On univariate analysis, T2bN0 disease versus T2aN0 treated with RT alone (p = .03) was significantly associated with inferior local control. CONCLUSION: Patients with glottic cancer with impaired vocal cord mobility (T2b) have a high rate of local failure with RT alone. The addition of concurrent chemotherapy should be considered for patients highly motivated toward larynx preservation and willing to accept the potential toxicity. © 2016 Wiley Periodicals, Inc.

Vocal fold mobility as the main prognostic factor of treatment outcomes and survival in stage II squamous cell carcinomas of the glottic larynx.

OBJECTIVE: This study aimed to assess the influence of supra- and subglottic extensions and vocal fold mobility on outcome in a large monocentric cohort of 148 patients treated for tumour-node-metastasis stage T2N0 glottic carcinomas. METHODS: In all, 107 glottic carcinoma patients had normal vocal fold mobility (T2aN0), and 41 had impaired vocal fold mobility (T2bN0). Treatment decisions were made by a multidisciplinary team. RESULTS: Vocal fold mobility was associated with overall survival, disease-free survival, local control, larynx preservation and laryngectomy-free survival. For patients with T2a lesions, local control, laryngectomy-free survival and disease-free survival improved after surgery but overall survival did not. For patients with T2b lesions, local control, laryngectomy-free survival, disease-free survival and overall survival were all higher after surgery than after radiotherapy. CONCLUSION: This study highlights for the first time the importance of vocal fold mobility in treatment outcomes and is the first to assess its influence on survival. Updated tumour-node-metastasis classifications should consider the distinction between T2a and T2b lesions.

Parálisis de cuerda vocal izquierda como complicación de la cirugía del ductus arterioso persistente / Left vocal cord paralysis after patent ductus arteriosus surgery

INTRODUCCIÓN: El ductus arterioso persistente (DAP) es frecuente en prematuros. Su cierre quirúrgico puede causar parálisis de cuerda vocal izquierda (PCVI) por lesión del recurrente. MATERIAL Y MÉTODOS: Estudio retrospectivo de prematuros con DAP de nuestro centro entre 1999-2013. Revisamos sus características y complicaciones de tratamiento. En los pacientes intervenidos se realizó una encuesta sobre síntomas relacionados con PCVI y se ofertó realizar una laringoscopia. RESULTADOS: Revisamos 88 pacientes diagnosticados de DAP en el período de estudio. Doce (13,64%) precisaron cirugía, los de menor edad gestacional y peso al nacer, teniendo mayor necesidad de ventilación mecánica e incidencia de parálisis diafragmática, displasia broncopulmonar y hemorragia intraventricular. El 33,3% (3/9) de los pacientes intervenidos tuvieron PCVI, presentando disfonía todos ellos (100 vs 16,7%, p = 0,05). DISCUSIÓN: La PCVI es una complicación frecuente de la cirugía del DAP. Serían necesarios más estudios que aclaren sus factores de riesgo y consecuencias a corto y largo plazo

INTRODUCTION: Patent ductus arteriosus (PDA) is a common problem in preterm newborns. Left vocal cord paralysis (LVCP) can complicate surgical closure if the recurrent nerve is damaged. MATERIALS AND METHODS: A retrospective case series study was conducted on preterm babies diagnosed with PDA in our unit from 1999 to 2013. Their clinical features and treatment complications were reviewed. In those patients that received surgical treatment a telephone uestionnaire on the symptoms of LVCP symptoms was completed, and laryncoscopy examination offered. RESULTS: A total of 88 subjects diagnosed with PDA were found, of whom 13.64% (12/88) needed surgery. These patients had a lower gestational age and birth weight. They required mechanical ventilation more frequently, and they had more complications such as, diaphragmatic paralysis, bronchopulmonary dysplasia and intraventricular hemorrhage. One third (3/9) of the surgically treated patients had LVCP, and all of them had dysphonia (100% vs. 16.7%, p = .05). DISCUSSION: LVCP is a common complication of PDA surgery. Further studies are needed to determine its risk factors and its short and long-term consequences

Should an involved but functioning recurrent laryngeal nerve be shaved or resected in a locally advanced papillary thyroid carcinoma?

BACKGROUND: The issue of whether an involved but functioning recurrent laryngeal nerve (RLN) should be shaved or resected in locally advanced papillary thyroid carcinoma (PTC) remains controversial. Our study aimed to compare the early and late outcomes between those who underwent shaving and those who underwent resection and also to identify independent prognostic factors in this subset of patients. METHODS: Of the 77 patients with 1 RLN involved by PTC, 39 (50.6%) underwent RLN preservation (group I) while 38 (49.4%) underwent RLN resection (group II). Early and late vocal cord function (as assessed by flexible laryngoscopy) and disease status were compared between the 2 groups. A multivariate Cox proportional hazards model was carried out to identify independent factors. RESULTS: Baseline characteristics were comparable between the 2 groups. Although temporary vocal cord palsy rate was similar between the 2 groups (p=0.532), 5 patients in group II (13.2%) suffered temporary bilateral vocal cord palsies with 1 requiring a tracheostomy lasting for 1 month. After a median follow-up of 113.8 months, 1 patient from each group developed new onset vocal cord palsy. Presence of distant metastases (hazard ratio [HR]=5.892, 95% CI=1.971-17.604, p=0.001) and incomplete surgical resection in non-RLN concomitant sites (HR=2.491, 95% CI=1.181-5.476, p=0.024) were the 2 independent predictors for a poor cancer-specific survival. CONCLUSIONS: Our data suggested that shaving could preserve the normal functionality in most of the involved RLNs (>90%) in the short to medium term. In the presence of distant metastases or incomplete resection in other non-RLN concomitant sites, the argument for shaving over resection appears even stronger.

Single-center experience of outcomes of tracheostomy in children with congenital heart disease.

OBJECTIVE: A subset of children with repaired congenital heart disease (CHD) may require tracheostomy for ongoing ventilatory support. Data on outcomes of children with CHD and tracheostomy are scarce. Our objectives were to describe indications for tracheostomy and outcomes, including readmission data in this population. METHODS: This is a retrospective chart review of children (<18 years old) with CHD who underwent tracheostomy at a single center over a 12-year period. Exclusion criteria were prematurity with isolated patent ductus arteriosus ligation. Outcomes until discharge and data on all readmissions after the initial discharge were reviewed. RESULTS: A total of 21 subjects with CHD underwent tracheostomy at a median (range) age of 4 (1-84) months and mean (standard deviation) weight of 7.2 (5.9) kg. The most common indication for tracheostomy was tracheomalacia with ventilator-dependent respiratory failure (14/21 subjects), followed by subglottic stenosis (5) and vocal cord palsy (2). Genetic syndromes were present in 13 (62%) subjects. The mean (standard deviation) post-tracheostomy length of stay was 55 (35) days. All subjects survived to discharge; 17 (81%) required home ventilation. A total of 11 (52%) subjects died during follow-up, all of whom were mechanically ventilated while three (14%) children underwent successful decannulation. The mean number of nonelective readmissions decreased from 2.4/patient-year in the first year to 1.4/patient-year in the second year, respectively. The commonest reasons for readmission were respiratory deterioration, infections, and mechanical tracheostomy-related problems. CONCLUSIONS: The majority of children with CHD who underwent tracheostomy did so for ventilator dependence and tracheomalacia and had coexisting genetic syndromes. About half the cohort died; among survivors, readmissions were common but decreased after the first year. These results underscore the ongoing mortality and morbidity risks faced by this vulnerable population.

Vocal cord paralysis after aortic surgery.

OBJECTIVE: The purpose of this study was to investigate variables associated with vocal cord paralysis during complex aortic procedures. DESIGN: A retrospective review. SETTING: A tertiary care center. PARTICIPANTS: Four hundred ninety-eight patients who underwent aortic surgery between 2002 and 2007. METHODS: Two groups were studied. Group A patients had procedures only involving their aortic root and/or ascending aorta. Group B patients had procedures only involving their aortic arch and/or descending aorta. RESULTS: The incidence of vocal cord paralysis was higher (7.26% v 0.8%) in group B patients (p < 0.0001). Increasing the duration of cardiopulmonary bypass time was associated with an increased risk of vocal cord paralysis and death in both groups A and B (p = 0.0002 and 0.002, respectively). Additionally, within group B, descending aneurysms emerged as an independent risk factor associated with vocal cord paralysis (p = 0.03). Length of stay was statistically significantly longer among group A patients who suffered vocal cord paralysis (p = 0.017) and trended toward significance in group B patients who suffered vocal cord paralysis (p = 0.059). The association between tracheostomy and vocal cord paralysis among group A patients reached statistical significance (p = 0.007) and trended toward significance in group B patients (p = 0.057). CONCLUSIONS: Increasing duration of cardiopulmonary bypass time was associated with a higher risk of vocal cord paralysis in patients undergoing aortic surgery. Additionally, within group B patients, descending aortic aneurysm was an independent risk factor associated with vocal cord paralysis. Most importantly, vocal cord paralysis appeared to have an association between an increased length of stay and tracheostomy among a select group of patients undergoing aortic surgery.

Early complications after pneumonectomy: retrospective study of 168 patients.

The purpose of this study was to assess the mortality and risk factors of complications after pneumonectomy for lung cancer. Between 1996 and 2001, we reviewed and analysed the demographic, clinical, functional, and surgical variables of 168 patients to identify risk factors of postoperative complications by univariate and multivariate analyses with Medlog software system. The mean age was 60+/-10 years, overall mortality and morbidity rates were 4.17% and 41.6%, respectively. All frequencies of respiratory complications were 1.2% for acute respiratory failure, 10.1% for pneumonia, 2.4% for acute pulmonary oedema, 4.17% for bronchopleural fistula, 2.4% for thoracic empyema and 18.5% for left recurrent nerve injuries. Postoperative arrhythmias developed in 46% of our patients. The risk factors for cardiopulmonary morbidity and mortality with univariate analysis were advanced age (P<0.01), preoperative poor performance status (P<0.015), and chronic artery disease (P<0.008). Factors adversely affecting morbidity with multivariate analysis included age (P=0.0001), associated cardiovascular disease (P=0.001), and altered forced expiratory volume in 1 s (P=0.0005). Complications after pneumonectomy are associated with high mortality. Careful attention must be paid to patients with advanced age and heart disease. Chest physiotherapy is paramount to have uneventful outcomes.

Airway management in anaplastic thyroid carcinoma.

OBJECTIVES/HYPOTHESIS: In patients who present with advanced anaplastic thyroid cancer, airway management is difficult because of bilateral vocal cord paralysis or tracheal invasion by the tumor. Airway management can be extremely complex in these patients. STUDY DESIGN: This is the author's 25 year experience with 30 patients who presented with anaplastic thyroid cancer and acute airway problems. METHODS: The patients' airway issues developed soon after presentation or a few months after treatment. Ten patients presented with initial symptoms of acute airway distress. All of these patients were treated with tracheostomy or cricothyrotomy. RESULTS: The 10 patients who presented with initial symptoms of acute airway distress died within 4 months. Eight of the remaining 20 patients developed bilateral vocal cord paralysis. Airway management for these patients depended on the extent of distant disease and the family's understanding of the advanced nature of the disease and the palliative efforts. The remaining patients had a palliative and supportive approach. CONCLUSIONS: Airway management was the most critical issue in patients who presented with anaplastic thyroid cancer and initial airway distress. Cricothyrotomy was helpful in avoiding acute airway catastrophe. It is important to distinguish between poorly differentiated and anaplastic thyroid cancer and lymphoma for appropriate airway management.

Thyroplasty type I with Montgomery implant among native French language speakers with unilateral laryngeal nerve paralysis.

OBJECTIVE: To document the long-term results achieved with the Montgomery implant in 96 French speakers with a unilateral laryngeal nerve paralysis (ULNP). STUDY DESIGN: Retrospective series, inception cohort of 96 patients. METHODS: Data regarding morbidity and functional results were obtained at regular visits to our clinic. All patients were followed for a minimum of 6 months or until death. Forty-two patients had a minimum of 12 months of follow-up. Early in the study, 36 patients were prospectively recorded under similar conditions before placement of the Montgomery implant and at 1, 3, 6, and 12 months postoperatively. RESULTS: None of the 96 patients died in the immediate postoperative period. The perioperative course was unremarkable in 94.8% of cases. Perioperative problems included failure to obtain a satisfactory phonatory result in three patients, difficulty to stabilize the implant posteriorly in one patient, and fracture of the inferior rim of the thyroid cartilage window in another patient. The primary immediate postoperative problem (within the first postoperative month) was laryngeal dyspnea, noted in four patients. According to the patient's subjective assessment, speech and voice was always improved in the immediate postoperative period. However, three patients had secondary degradation of speech and voice. Revision surgery under local anesthesia resulted in a 97.9% ultimate speech and voice success rate. According to the patient's subjective assessment, adequate swallowing in the immediate postoperative period was achieved in 94.2% of cases that had swallowing problems preoperatively. A significant statistical increase in the duration parameters (phonation time, phrase grouping, speech rate) together with a statistical significant decrease in both the jitter and shimmer values was noted when comparing the preoperative and the postoperative values at 1 month. Analysis of the evolution of the speech and voice parameters at 1, 3, 6, and 12 months postoperatively showed a significant decrease in the fundamental frequency and noise-to-harmonic ratio values but did not demonstrate any significant differences for the other speech and voice parameters. CONCLUSIONS: From the reported data, we conclude that the type I thyroplasty with Montgomery implant insertion is a safe and reproducible method to treat ULNP. Furthermore, this system achieves very good and stable phonatory results. Finally, the use of this technique and implant system appears safe in patients from various cultures with ULNP from a variety of causes and severe comorbidity. Over the past decade at our department, this procedure progressively replaced the use of the intracordal injection of autologous fat injection that was initially advocated in patients with ULNP.

Palliative surgery for neoplastic unilateral vocal cord paralysis.

BACKGROUND: Locally advanced, recurrent or metastatic neoplasms are the commonest causes of unilateral vocal cord paralysis (UVCP). The aim of the present study was to evaluate both survival and results of treatment of vocal cord medialization procedures in this group of patients. METHODS: Fifty-seven patients (36 male, 21 female) with UVCP considered to be due to advanced malignancy who underwent medialization (Teflon injection or type I thyroplasty) between January 1994 and July 2000 were retrospectively reviewed. RESULTS: The malignancy responsible for UVCP was non-small-cell lung carcinoma (NSCLC) in 43 patients, small-cell lung carcinoma (SCLC) in four patients, thyroid carcinoma in three patients and metastatic lower cervical lymph nodes in seven patients. All patients complained of dysphonia and 29 patients had symptoms of aspiration. Teflon injection was performed in 44 patients and thyroplasty in 13. Improvement in voice occurred in 51 patients (89%) and resolution of aspiration in 28 patients (97%) after 2 months. The median time from onset of symptoms of UVCP to death in NSCLC was 170 days; SCLC, 69 days; thyroid carcinoma, 783 days; and metastatic lower cervical lymph nodes, 304 days. CONCLUSION: Surgical treatment of neoplastic UVCP provides satisfactory palliation of symptoms, and management decisions should be based on patient survival expectations.

Vocal cord dysfunction after left lung resection for cancer.

OBJECTIVES: To evaluate the prevalence, the impact-related postoperative complications and the risk factors of vocal cord dysfunction (VCD) after left lung resection for cancer. METHODS: From February 1996 to April 1999, a review of prospectively gathered data was performed on 99 consecutive patients who underwent a pneumonectomy (n=50) or a lobectomy (n=49) with a mediastinal lymph node dissection. A fiber optic laryngeal examination was performed preoperatively for all patients and within the first week postoperatively in patients with symptom(s) or sign(s) of VCD or respiratory complications. RESULTS: Thirty-one patients (31%) had a postoperative VCD (group VCD) and 68 (68%) did not (group non-VCD). Mortality rate was 19% in group VCD and 9% in group non-VCD (P=0.13). Group VCD patients developed more pulmonary complications (P=0.014) and cardiac complications (P<0.001) compared to group non-VCD patients. A higher rate of reintubation (P=0.005), pneumonia (P=0.06), arrhythmia (P=0.002), cardiac failure (P<0.001) was noticeable in group VCD and may account for the higher rate of complications in this group. Using multivariate analysis, preoperative radiotherapy (P=0.001) and pneumonectomy (P=0.008) were predictive of postoperative VCD. Hospital stay was 22+/-16 days in group VCD and 13+/-9 days in group non-VCD (P<0.002). CONCLUSION: VCD is a frequent event that can lead to dramatic pulmonary complications. We would recommend to track it and to treat it as early as possible.

[Prognostic factors in highly malignant thyroid tumors]. / Prognostische Faktoren bei hochmalignen Schilddrüsentumoren.

Patients diagnosed as suffering from highly malignant thyroid tumours die within a few months due to rapid tumour progression. Survival depends on some valuable prognostic factors, namely tumour size, lymph node involvement, metastatic status, fast tumour growth and preoperative N. recurrens paresis. Life expectation and life quality are dependent on the feasibility of radical surgical treatment. It is necessary to remove the whole tumour to improve the survival rate and to reduce the incidence of local recurrence. Some highly malignant thyroid tumours show a high chemosensitivity.
