Journal of the Korean Dysphagia Society.2018;8(1):48-55.

OBJECTIVE: This study was conducted to identify the frequency of videofluoroscopic swallow study (VFSS) and characteristics of VFSS findings in the patients diagnosed with aspiration pneumonia. METHOD: We retrospectively reviewed the medical records of 2,885 patients who has been diagnosed with aspiration pneumonia either clinically or radiographically. Overall, 811 patients could not be examined because of medical problems. The rest of the subjects were divided into two groups according to the presence of neurologic deficit. The findings of VFSS were scored using the Penetration-Aspiration Scale (PAS) and Pharyngeal Residue Grade (PRG), and data were analyzed based on descriptive statistics, the χ² test, t-test, ANCOVA and logistic regression. RESULT: A total of 1,267 subjects (43.9%) underwent VFSS. Among patients who could be examined, 61.1% were tested. Only 26.7% of subjects without neurologic deficit underwent VFSS, while 56.5% of the subjects in the other group underwent the procedure. The PAS and PRG scores did not differ significantly between groups. About 32.7% of the findings showed silent aspiration (PAS 8), which difficult to detect by bedside screening tests. CONCLUSION: Subjects with neurologic deficit showed significantly higher test rates than the others. There were no significant differences in VFSS findings between groups. Dysphagia should be evaluated in patients with aspiration pneumonia using precise tools, such as VFSS and fiberoptic endoscopic evaluation of swallowing (FEES), regardless of presence of neurological deficit.

Ji Eun LEE ; Eun Jeong LEE

Journal of the Korean Dysphagia Society.2018;8(1):41-47.

OBJECTIVE: Currently, there are no established dietary guidelines for patients with swallowing difficulties in Korea. Therefore, this study was conducted to develop an organized set of dietary guidelines listing simple yet diverse ingredients that are safe for consumption and have high nutritional quality. METHOD: Ninety patients with swallowing and masticatory dysfunction admitted in hospitals A and B were enrolled in this study. The initial study phase encompassed a 6-month period at each site from May 2016 to June 2017. The patients fed according to the dietary guidelines developed in this study were observed. The before- and after-care variances were observed by measuring the patients' weight, and TLC as well as the levels of serum albumin and food intake. This observation was based on the classification of swallowing difficulty and masticatory dysfunction into four scales. RESULT: The before- and after-care weight measurements of the study patients revealed a shift from 48.60±10.17 to 49.32±10.23 kg, and a change in the BMI from 20.04±3.91 to 20.33±3.93. The variances were deemed statistically significant, indicating that the nutrition index of the administered diet was adequate. An analysis of the types of food intake of side dishes and snacks before- and after- dietary administration per study revealed 3.58±1.01 to 4.19±0.83 and 2.77±0.98 to 3.49±1.21, respectively. CONCLUSION: The food intake level and the weight and BMI of patients in both hospitals increased during the 1-year study period. Furthermore, increasing the dietary level from the third to the fourth tier on an institutional basis enabled a systematic configuration of dietary formulations for each stage of this disorder.

Journal of the Korean Dysphagia Society.2018;8(1):35-40.

OBJECTIVE: To evaluate the factors affecting long-term prognosis for dysphagia in tonsil cancer patients, after treatment. METHOD: This was a retrospective study of subjects who underwent a videofluoroscopic swallowing study (VFSS) following treatment for stage 3 or 4 tonsil cancer. Data including sex, age, cancer characteristics, and methods of cancer treatment were collected. To evaluate the swallowing-related outcome, we collected data including findings regarding the last VFSS, method of feeding, and history of aspiration pneumonia requiring in-patient care. We evaluated the correlation between these data and the characteristics of cancer and treatment methods. RESULT: Among 32 subjects included in this study, eight had aspiration or penetration confirmed by the last VFSS. There were no significant differences in swallowing-related factors according to the presence of aspiration or penetration in the last VFSS. Patients who underwent curative tonsillectomy retained more residues on the last VFSS than those who did not. CONCLUSION: Among subjects with tonsil cancer, history of curative tonsillectomy was correlated with more pharyngeal residue. However, other cancer- or treatment-related factors did not affect the outcome of swallowing.

Journal of the Korean Dysphagia Society.2018;8(1):30-34.

OBJECTIVE: Pharyngoesophageal stricture formation and dysphagia following total laryngectomy negatively affect quality of life and result in nutritional compromise that can be successfully managed with various techniques. This study was conducted to describe our experiences of office-based balloon dilatation by transnasal endoscopy, which can be performed by an otolaryngologist. METHOD: The present study investigated three patients who underwent transnasal endoscopy guided balloon dilatation of pharyngoesophageal stricture. The assessment was performed based on the number of procedures and recurrences, final subjective outcomes, and complications. RESULT: There were no post-procedural complications. In one patient, a scarric band was found after the procedure; therefore, steroids were injected into the stricture site. There were 2–3 balloon dilatations and the interval between dilatations was 3–6 months. All patients were able to tolerate solid diet after 2 or 3 sessions. CONCLUSION: Transnasal endoscopic balloon dilatation, which can be easily performed by an otolaryngologist in an office setting without sedation or general anesthesia, can be a useful modality for treating pharyngoesophageal stricture after total laryngectomy.

Journal of the Korean Dysphagia Society.2018;8(1):23-29.

OBJECTIVE: This study was conducted to evaluate the influence of supraglottic swallowing maneuver on swallowing kinematics using kinematic analysis of a videofluoroscopic swallowing study (VFSS). METHOD: Twenty healthy volunteers (10 in a young group ( < 40 years) and 10 in an elderly group (≥60 years)), participated in this study. After structured instruction by a skilled physician, the subjects swallowed 5 ml of diluted barium in the neutral position without any swallowing maneuvers, as well as with supraglottic swallow maneuver under digital videofluoroscopy, three times each. Kinematic analysis was conducted by digitization of video files for movements of hyolaryngeal structures, including the hyoid bone, larynx, arytenoid, and epiglottis. We measured the maximum displacements and velocities of the hyolaryngeal structures during swallowing. RESULT: The most remarkable change in supraglottic swallow was the maximum vertical displacement (mm) of the hyoid bone during swallowing in both groups (11.5±3.34–19.7±6.88 in the young group, P=0.009; 13.4±2.13–22.8±5.35 in the elderly group, P < 0.001). For velocity variables, patterns of change differed between the young and elderly groups. In the young group, the maximum vertical velocities of the larynx and arytenoid were decreased (P < 0.05), but in the elderly group, the maximum 2D velocity of hyoid bone, maximum horizontal and 2D velocity of the larynx and maximum horizontal velocity of the arytenoid were increased (P < 0.05). There were no significant differences in changes between the young and elderly groups. CONCLUSION: This study showed that supraglottic swallow could affect hyolaryngeal movements, particularly vertical hyoid movement, during swallowing. Beneficial kinematic changes in supraglottic swallow were more pronounced in the elderly group. Therefore, supraglottic swallow may contribute to swallowing improvement by enhancing hyolaryngeal movements during swallowing, in addition to laryngeal closure.

Dysphagia due to Chemical Injury or Cervical Spine Injury

Yoon Se LEE

Journal of the Korean Dysphagia Society.2018;8(1):15-22.

Caustic injury and spinal cord injury may induce pharyngeal and esophageal dysfunction, which frequently elicit dysphagia. Among the causes of dysphagia, these types of injury are related to anatomical and functional deterioration of the peripheral muscles and nerves. Various types of chemical materials cause upper aerodigestive tract burns, which induces stricture and dysphagia by scar formation. Endoscopic evaluation within 48 hours helps to predict the occurrence of stricture and dysphagia. The extent of injury or other additional complications should be assessed by plain X-ray and comupterized tomography (CT). The prevention of stricture, perforation, and dysphagia is a mainstay of treatment to reduce morbidity, and serial dilation with esophagogram and flap reconstruction should be considered in failure cases. Cervical spine injury itself causes mucosal tears or neuromuscular dysfunction, which can occur even during corrective surgery. Perforation should be evaluated by laryngoscopy, swallowing studies, plain X-ray, and CT. Both mechanical and functional obstruction that occur during the healing process can be managed by rehabilitative or surgical approaches. Dysphagia caused by chemical burns or cervical spine injury can provoke secondary complications such as aspiration pneumonia and malnutrition. Thus, adequate evaluation and management of anatomical and functional changes are required to prevent dysphagia and further complications, as well as to increase the quality of life of patients.

Therapeutic Exercises for Strengthening Suprahyoid Muscles

Ji Su PARK ; Na Kyoung HWANG ; Dong Hwan OH ; Moon Young CHANG

Journal of the Korean Dysphagia Society.2018;8(1):8-14.

Suprahyoid muscles play an important role in normal swallowing by providing muscle contractions involved in airway protection and upper esophageal sphincter opening. However, these muscles can be weakened by neurological disease or aging, which can result in pharyngeal dysphagia. Therefore, strengthening of the suprahyoid muscles is a clinically important treatment. In addition, it is important to know exactly how and which method is optimal. Many therapeutic exercise methods have been reported to strengthen the suprahyoid muscles, and new methods related to this have recently been reported. Therefore, this study will briefly summarize the representative traditional methods and the recently reported, relatively new methods for strengthening the suprahyoid muscles.

Dysphasia due to Oral Anomaly

Jun Hee HONG ; Yong Jae JOUNG ; Kang Min AHN

Journal of the Korean Dysphagia Society.2018;8(1):1-7.

Dysphasia related to oral anomaly is a common situation in oral and maxillofacial surgery. The etiology of oral anomalies causing dysphasia can be divided into congenital and acquired disease. Congenital diseases include teratoma or benign tumors and congenital defects such as cleft lip and palate. Benign tumors include cystic hygroma in the neck and hemangioma in the tongue. Certain syndromes with macroglossia and micrognathia are also related to difficulty in swallowing. The three common syndromes are Pierre-Robin syndrome, Beckwith-Widermann syndrome and ectodermal dysplasia. Taken together, these congenital diseases require a multi-discipline approach to obtain optimal results. Representative disease of acquired dysphasia is the oral cavity cancer. Cancer ablation results in tissue defect and decreased motor function. Free flap reconstruction is the choice of treatment following oral cavity caner operation; however, dysphasia after cancer operation is inevitable. In this review article, the full scopes of oral anomaly associated with dysphasia were classified and treatment was suggested.

Dysphagia as a Clinical Manifestation of Monoclonal Gammopathy of Undetermined Significance: A Case Report

Hyunjung KOO ; Geun Young PARK ; Yeonjae HAN ; Sangah JEONG ; Sun IM

Journal of the Korean Dysphagia Society.2019;9(2):93-98. doi:10.34160/jkds.2019.9.2.007

Swallowing can be affected by a variety of systemic diseases. The etiology of dysphagia in the geriatric population is usually overlooked due mainly to a presumed diagnosis of presbyphagia or difficulty in revealing the direct cause. On the other hand, dysphagia can be a meaningful clinical sign of premalignant systemic disease. A 78-year-old man, without any prior medical or family history, was admitted with the chief complaint of dysphagia with recent aspiration pneumonia. Instrumental swallowing tests revealed a severe degree of dysphagia due to decreased laryngopharyngeal sensation and weakness of the pharyngeal constrictor muscles. Extensive workup, including electromyography and laboratory tests, revealed severe sensorimotor peripheral polyneuropathy related to monoclonal gammopathy. Monoclonal gammopathy of undetermined significance (MGUS) is a premalignant precursor of multiple myeloma, which is characterized by the proliferation of monoclonal proteins. These conditions are often associated with peripheral polyneuropathy, ataxia, and sometimes even muscle weakness. Although dysphagia can occur in other systemic disorders, such as vasculitis or paraneoplastic syndrome-related malignancies, there are few reports of dysphagia related to MGUS. The patient was followed up for three years. The MGUS showed no further progression, but the patient showed no improvement, indicating a protracted clinical course and poor prognosis when dysphagia is related to MGUS.

Journal of the Korean Dysphagia Society.2019;9(2):89-92. doi:10.34160/jkds.2019.9.2.006

Dysphagia caused by a functional gastric outlet obstruction is rare and the natural course of a functional gastric outlet obstruction is unclear. This paper reports a patient with dysphagia and a functional gastric outlet obstruction after a cervical esophagogastrostomy. A 62-year-old man with a history of esophageal cancer and cervical esophagogastrostomy presented with dysphagia and discomfort during meals. A videofluoroscopic swallowing study (VFSS) with barium revealed a mild increase in the post-swallow remnants and delayed emptying of the gastric outlet, reflecting a functional gastric outlet obstruction at the diaphragm. One month later, VFSS revealed a worsened functional gastric outlet obstruction at the diaphragm. A delayed chest X-ray showed worsened delayed emptying of the gastric outlet. A cervical esophagogastrostomy for early esophageal cancer can cause functional gastric outlet obstruction, presenting as dysphagia and discomfort during meals. Physicians should be concerned about dysphagia and the functional changes in the esophagus in patients with a cervical esophagogastrostomy.
