An anterior cervical osteophyte is one of the causes of dysphagia. Surgical treatment is one of the treatment options available, and previous studies have suggested that it is an immediate and effective treatment. This paper reports a case of temporarily aggravated dysphagia after surgical treatment in a patient with anterior cervical osteophyte. A 75-year-old male complained of dysphagia for one year. A videofluoroscopic swallowing study (VFSS) revealed anterior cervical osteophytes at the C3 and C4 level, which resulted in decreased epiglottic folding and partial obstruction of the bolus passage. After he underwent osteophytectomy and anterior fixation, the post-operative VFSS showed an aggravation of dysphagia with prevertebral soft tissue edema. The major cause of dysphagia was attributed to the limitation of movement of the posterior pharyngeal wall and upper esophageal sphincter due to the increased prevertebral soft tissue thickness. In conclusion, surgery should be considered when a severe dysphagia is persistent after adequate conservative treatment in patients with dysphagia due to anterior cervical osteophytes, and patients at high risk of postoperative dysphagia might require swallowing rehabilitation.

The prevalence of people presenting with fish bone foreign body (FFB) is high in Asian countries, including Korea, and coastal areas around the world. Pointed linear-shaped FFBs are common in the oral cavity and upper esophageal sphincter, whereas large flat bones are more common FFBs in the esophagus. If the FFB is not found on endoscopy, residual foreign body sensation or embedded FFB is possible. In such cases, CT is helpful. However, in the case of totally embedded FFB, not only preoperative diagnosis but also localization during operation or surgery is important. If these are not performed, the initial incision site or operation method would be difficult to determine. For this purpose, no standard guideline has been established yet. We report a case of upper esophageal sphincter-embedded FFB diagnosed using CT rather than endoscopy. The bone was successfully localized using conventional ultrasonography during the operation and then removed surgically.

Gastroesophageal reflux disease (GERD) is a very common disease, and the prevalence in the general population has recently increased. GERD is a chronic relapsing disease associated with motility disorders of the upper gastrointestinal tract. Several factors are implicated in GERD, including hypotensive lower esophageal sphincter, frequent transient lower esophageal sphincter relaxation, esophageal hypersensitivity, reduced resistance of the esophageal mucosa against the refluxed contents, ineffective esophageal motility, abnormal bolus transport, deficits initiating secondary peristalsis, abnormal response to multiple rapid swallowing, and hiatal hernia. One or more of these mechanisms result in the reflux of stomach contents into the esophagus, delayed clearance of the refluxate, and the development of symptoms and/or complications. New techniques, such as 24-hour pH and multichannel intraluminal impedance monitoring, multichannel intraluminal impedance and esophageal manometry, high-resolution manometry, 3-dimensional high-resolution manometry, enoscopic functional luminal imaging probe, and 24-hour dynamic esophageal manometry, provide more information on esophageal motility and have clarified the pathophysiology of GERD. Proton pump inhibitors remain the preferred pharmaceutical option to treat GERD. The ideal target of GERD treatment is to restore esophageal motility and reconstruct the anti-reflux mechanism. This review focuses on current advances in esophageal motor dysfunction in patients with GERD and the influence of these developments on GERD treatment.

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.

Prolonged intubation is known to bring on postextubation dysphagia (PED) in some patients. We have noted that there were some studies to investigate specific type and pattern of PED, which showed large variety of different swallowing abnormalities as mechanisms of PED that are multifactorial. There are several options of treatment in accordance with the management of these abnormalities. A botulinum toxin (BoT) injection into the upper esophageal sphincter (UES) can improve swallowing functions for patients with this disorder, by working to help the muscle relax. In this case, the conventional treatment was not effective in patients with PED, whereas the BoT injection made a great improvement for these patients. This study suggests that the UES pathology could be the main cause of PED.

OBJECTIVE: To evaluate the characteristics of cricopharyngeal dysfunction (CPD), the frequency, and correlation with a brain lesion in patients with first-ever ischemic stroke, and to provide basic data for developing a therapeutic protocol for dysphagia management. METHODS: We retrospectively reviewed the medical records of a series of subjects post-stroke who underwent a videofluoroscopic swallowing study (VFSS) from January 2009 to December 2015. VFSS images were recorded on videotape and analyzed. CPD was defined as the retention of more than 25% of residue in the pyriform sinus after swallowing. The location of the brain lesion was assessed using magnetic resonance imaging. RESULTS: Among the 262 dysphagic patients with first-ever ischemic stroke, 15 (5.7%) showed CPD on the VFSS. Patients with an infratentorial lesion had a significantly higher proportion of CPD than those with a supratentorial lesion (p=0.003), and lateral medullary infarction was identified as the single independent predictor of CPD (multivariable analysis: odds ratio=19.417; confidence interval, 5.560–67.804; p < 0.0001). Compared to patients without CPD, those with CPD had a significantly prolonged pharyngeal transit time, lower laryngeal elevation, and a higher pharyngeal constriction ratio and functional dysphagia scale score. CONCLUSION: Overall, the results support the notion that an impaired upper esopharyngeal opening is likely related to the specific locations of brain lesions. The association of CPD with lateral medullary infarction can be explained based on the regulation of the pharyngolaryngeal motor system by the motor neurons present in the dorsal nucleus ambiguus. Overall, the results reveal the relation between CPD and the problems in the pharyngeal phase as well as the severity of dysphagia.

The known causes of dysphagia following cervical spine surgery include pre-vertebral soft tissue swelling, decreased posterior pharyngeal movement, and impaired upper esophageal sphincter opening. Some studies have suggested that dysphagia is associated with movement of the cervical vertebrae during swallowing. In the present case, a 59-year-old man with a limited cervical range of motion due to ankylosing spondylitis slipped and fell, resulting in a C7 vertebral body fracture. He underwent anterior cervical discectomy as well as C5-T1 anterior fusion and C5-T2 level postero-lateral fusion. After surgery, he showed signs and symptoms of aspiration. A video-fluoroscopic swallowing study (VFSS) revealed incomplete laryngeal elevation, cricopharyngeal dysfunction, and vallecular remnant. Aspiration was observed in the semisolid-swallowing test. The patient's dysphagia could be attributed to two main causes. First, the esophagus might have been compressed by thickened pre-vertebral soft tissue after surgery. Second, the cervical range of motion, which was already limited by ankylosing spondylitis, might have been limited further by the anterior fusion of the cervical spine. In conclusion, a preoperative evaluation, including VFSS, should be considered before cervical spinal surgery, particularly in patients with ankylosing spondylitis presenting with a limited cervical range of motion.

BACKGROUND AND OBJECTIVES: The main treatment of laryngopharyngeal reflux disease (LPRD) includes life style modification and proton pump inhibitor (PPI) medication. However, LPRD is sometimes refractory to PPI medication. The Reza band has been developed to exert external pressure on the upper esophageal sphincter thus preventing gastric acid reflux to the larynx and pharynx. The aim of this study was to evaluate safety and efficacy of using the Reza band in patients with LPRD. SUBJECTS AND METHOD: We prospectively enrolled 16 LPRD patients who were refractory to PPI medication and who had agreed to wear the Reza band. Patients were treated with the Reza band and PPI medication simultaneously or only the Reza band. We studied complications related to the Reza band, analyzed Reflux Symptom Index (RSI) and Reflux Finding Score (RFS) before and after the application of the band up to 12 weeks. RESULTS: The Reza band was endured by 15 patients except one patient. One patient (6.25%) ceased wearing the band due to pain and discomfort in the neck. No major complications occurred, except one patient who reported mild neck discomfort when the band was applied. The mean value of RSI before the application of the Reza band was 12.31±6.43, which significantly improved at 8 weeks and 12 weeks (9.17±5.08, p=0.005 and 8.20±5.59, p=0.007, respectively) post-treatment. The mean value of RFS before the application of the Reza band was 13.50±2.97, which significantly improved at 2, 4, 8, and 12 weeks (p < 0.05) post-treatment. CONCLUSION: We conclude that the Reza band is safe and effective for the treatment of LPRD in properly selected patients.

The objective of this preliminary study is to investigate the effects of various head turn in hemiplegic stroke patients with pharyngeal dysphagia. Twenty hemiplegic stroke patients with dysphagia participated in this study. A patient with dysphagia from an upper esophageal sphincter disorder was excluded. All participants underwent a videofluoroscopic swallow study (VFSS) with a 3 mL liquid diet, and their heads were randomly turned to a neutral position, toward the weaker side, toward the stronger side, or to a chin tuck posture. To assess patient swallowing function with VFSS, the videofluoroscopic dysphagia scale (VDS) and penetration-aspiration scale (PAS) were conducted by a physiatrist blinded to the participant's characteristics. No significant improvements in the VDS and PAS were observed in patients with heads rotated toward the weaker or stronger side when compared with heads in the neutral position. However, there was a significant improvement in the VDS for heads in the chin tuck position when compared with those in the neutral position (p < 0.05). These preliminary results revealed that the head turn practice without VFSS, as a compensatory strategy, could not improve dysphagia in hemiplegic stroke patients. Therefore, compensatory postures might be re-considered with in hemiplegic stroke patients with pharyngeal dysphagia.

BACKGROUND/AIMS: We attempted to examine the relationship between abnormal findings on high-resolution manometry (HRM) and videofluoroscopic swallowing study (VFSS) of the pharynx and upper esophageal sphincter (UES), and to identify the risk factors for aspiration. METHODS: We performed VFSS and HRM on the same day in 36 ischemic stroke patients (mean age, 67.5 years) with dysphagia. Pressure (basal, median intra bolus, and nadir), relaxation time interval of the UES, and mesopharyngeal and hypopharyngeal contractility (as a contractile integral) were examined using HRM. The parameters of VFSS were vallecular residue, pyriform sinus residue, vallecular overflow, penetration, and aspiration. The association between the parameters of VFSS and HRM was analyzed by the Student's t test. RESULTS: Three (8.3%) and 4 (11.1%) stroke patients with dysphagia had pyriform sinus residue and vallecular sinus residue, respectively, and 5 (13.8%) patients showed aspiration. Mesopharyngeal and hypopharyngeal contractile integrals in patients with residue in the pyriform sinus were significantly lower than those in patients without residue in the pyriform sinus (P < 0.05). Relaxation time intervals in patients with aspiration were significantly shorter than those in patients without aspiration (P < 0.05), and multivariate regression analysis revealed a shorter relaxation time interval as the main risk factor for aspiration (OR, 0.03; 95% CI, 0.01–0.65; P < 0.05). CONCLUSIONS: Manometric measurements of the pharynx and UES were well correlated with abnormal findings in the VFSS, and a shorter relaxation time interval of the UES during deglutition is an important parameter for the development of aspiration.
