Functional outcomes of soft palate free flap reconstruction following oropharyngeal cancer surgery

IntroductionThe objective of this study was to assess the impact of surgical resection and free flap reconstruction of soft palate cancer on speech, swallowing and quality of life, and to identify the factors influencing functional outcomes and quality of life.Material and methodsPatients treated with surgical resection of squamous cell carcinoma and free-flap reconstruction of the soft palate were reviewed at least 12 months after surgery. Speech was assessed using the Hirose intelligibility scoring system, nasalance scoring, GRBAS scoring and the Voice Handicap Index 30 (VHI30) questionnaire. Swallowing was assessed by fiberoptic endoscopy and the Deglutition Handicap Index (DHI). Quality of life was assessed using EORTC QLQ-C30 and QLQ-H&N35 questionnaires.Results29 patients were included. Speech outcomes were satisfactory, demonstrating normal or slightly below normal speech intelligibility in 75.9% of the patients, moderate or no rhinolalia in 72.4% of the patients and mean overall VHI30 scores indicative of slight or no handicap in 86.2% of the patients. Swallowing outcomes were satisfactory, with mean overall DHI scores indicative of slight or no handicap in 82.8% of the patients. Patient quality of life was preserved as demonstrated by mean quality of life and functioning scales scores all superior to 80%.ConclusionThe sequelae arising from surgical resection and free-flap reconstruction of soft palate cancer are tolerable, involving slight handicap in terms of speech and swallowing and relatively little impact on quality of life.     

Voice outcome indicators for unilateral vocal fold paralysis surgery: A survey among surgeons

IntroductionStandardization of voice outcomes indicators (VOIs) is an important issue when it comes to evaluating and comparing surgical treatments for Unilateral Vocal Fold Paralysis (UVFP). In a recent review, 11 VOIs were found to represent 80% of the VOIs cited in the literature. A survey was launched among the European laryngologists to acquire surgeons’ opinions on the above mentioned preselected VOIs.Material and methodThe electronic survey took place between November and December 2016. Three general questions were asked about surgeon's practice setting(s) and experience. The eleven next questions concerned (a) surgeon's VOIs preference and (b) their estimates of post-operative target values, they would consider being satisfactory.ResultsThe response rate was 16% (50 surveys). The majority of responders worked in tertiary hospitals (50%), had 15 years of experience with UVFP and performed on average 20 UVFP related procedures a year. The VOIs that were favored by the responding surgeons were, in decreasing order of importance, Voice handicap Index (VHI-30), Maximum Phonation Time (MPT), GRBAS-I, Mean Airflow Rate (MeAF), Jitter and Shimmer. There was an excellent consensus on post-operative VOI target values between survey's results and the literature data, except for three VOIs that showed somewhat divergent tendencies (absolute VHI-30, Jitter and Shimmer).ConclusionsThree VOIs are favored by surgeons: VHI-30, MPT and GRBAS-I. Jitter and Shimmer, although very frequently reported and statistically valid in the literature, come last concerning surgeon's choice as VOI for UVFP treatment assessment.     

基于MRI动态图像观察吞咽时器官动度对头颈部肿瘤调强放疗靶区影响

目的 利用MRI技术连续采集头颈部肿瘤患者吞咽时图像,观察并测量软腭、舌、喉的运动规律及最大活动度。方法 随机选取2018年7月-10月在中国医学科学院肿瘤医院接受调强放疗的原发头颈部恶性肿瘤20例患者,其中男17例、女3例,中位年龄58.5岁(28~78岁)。20例患者中鼻咽癌7例,口腔癌3例,口咽癌5例,下咽癌3例,鼻腔鼻旁窦2例。根据AJCC第八版分期Ⅰ-Ⅱ期患者2例,Ⅲ期8例,Ⅳ期10例。结果 吞咽时软腭向上移动移动距离为(1.06±0.31) cm且服从正态分布,向后移动距离为(0.83±0.24) cm且近似正态分布。舌体向后移动距离为(0.77±0.22) cm,且服从正态分布。含压舌板行图像采集患者舌上移位移为0,无压舌板患者舌体中位上移距离为1.23 cm (0.59~1.41 cm)。喉向上移动距离为(1.14±0.22) cm且服从正态分布,向前移动的中位距离为0.4 cm (0.27~0.90 cm)。结论 吞咽运动有可能发生于头颈部肿瘤患者放疗过程中,并引起大体肿瘤体积(GTV)及周围正常组织移动;因此在制定放疗计划时应注意GTV至PGTV的个体化外放距离,以保证肿瘤处方剂量。     

Dysphagia in patients with moderate and severe obstructive sleep apnea

IntroductionThere is evidence that trauma caused by snoring in the pharynx could result in dysphagia in patients with obstructive sleep apnea, but the literature is still scarce to define the factors associated with the presence of dysphagia in these patients.ObjectivesTo analyze the occurrence of dysphagia and its clinical and polysomnographic features in patients with moderate and severe obstructive sleep apnea, in addition to verifying the impact of dysphagia on the quality of life of these patients.MethodsSeventy patients with moderate or severe apnea (apnea and hypopnea index – AHI > 15/hour) were selected. The patients underwent a sleep questionnaire, a quality of life in dysphagia questionnaire and a fiberoptic endoscopic evaluation of swallowing.ResultsA total of 70 patients were included in the study, of which 49 were men (70 %), with a mean age of 48.9 years. The fiberoptic endoscopic evaluation of swallowing was altered in 27.3 % and the most frequent alteration was the premature oral leakage with fluid. Comparing the groups with and without dysphagia, the female gender was the only clinical parameter that showed a trend of statistical significance in the group with dysphagia (p = 0.069). There was no statistical difference regarding the polysomnographic features and in the global quality of life score in dysphagia in the comparison between the groups.ConclusionsThe presence of dysphagia in patients with moderate to severe apnea is frequent and subclinical, reinforcing the need to investigate this symptom in this group of patients. However, the presence of dysphagia did not result in worsening in patients' quality of life, suggesting that, although frequent, its effect is mild. There was no relevance regarding the association of clinical and polysomnographic parameters with the presence of dysphagia.     

Influence of decrease in the muscle activity during mastication on occurrence of the Stage II transport

Purpose

The purpose of this study was to examine the hypothesis that in the process from food ingestion to swallowing, intentional decrease in the muscle activity during mastication would affect the number of chewing strokes, and thus the occurrence of Stage II transport (St2Tr) or the number of swallowing.

Beyond Efficacy and Effectiveness: Conducting Economic Analyses During Clinical Trials

Few studies have examined cost issues in the field of dysphagia. This study presents cost data collected during a clinical trial in speech–language pathology, demonstrating the types of cost analyses that can be conducted and highlighting obstacles and issues facing investigators who seek to conduct economic analyses in this arena. Seventy-nine patients were enrolled in the clinical trial to assess the impact of a swallowing intervention on swallowing and speech function. The patients were at least one year past treatment for head and neck cancer. No significant intervention differences were detected in these outcomes. A companion economic analysis was conducted in 37 of these patients using patient diaries and followup with identified health care providers. Analyses indicated that (1) the intervention did not significantly reduce health care expenditures; (2) indirect costs and costs of hospitalizations are both important factors to consider during a trial; and (3) health care costs of this population are high relative to the rest of the U.S. population. Attrition from the overall study population can pose a serious threat to the viability of an economic study. The article concludes with a discussion of how these issues can be addressed in future studies.This research was supported by NIH/NCI P01 CA40007 and NIDCD U01 DC03206.     

Prevalence of swallowing complaints and clinical findings among 50–79-year-old men and women in an urban population

To determine the prevalence of swallowing and esophageal complaints in the general population, 300 men and 300 women were asked to answer a mailed questionnaire. The participation rate was 92.5%. Complaints were reported by 35%. The most common complaints were symptoms associated with gastroesophageal reflux (GER) and globus sensation, both with a rate of occurrence of 20%. Obstruction of the bolus reported by 3% was the individual symptom that most frequently brought patients to the doctor. To validate the questionnaire and to study possible organic causes behind these symptoms, 46 persons with symptoms were invited to undergo further examination. Cineradiography of the pharynx revealed that 7 of 14 patients with symptoms of GER had abnormalities in the esophagus. Eleven of 55 patients with GER symptoms at least once a week underwent endoscopy. One case of erosive esophagitis and one case of gastric ulcer were diagnosed. Four of nine patients with obstructive symptoms had defective closure of the laryngeal vestibule shown by cineradiography. Endoscopy in four patients with obstructive symptoms revealed benign findings. Thus, an epidemiologic study of patients with swallowing symptoms documented a low incidence of serious organic disease.
