RESUMO
PURPOSE: To discuss the different swallowing improvement surgeries that address one or more dysfunctional pharyngolaryngeal structures causing dysphagia. These surgeries reduce the risk of aspiration without sacrificing vocal function. METHODS: We searched the PubMed database and used Google Scholar search engine to find studies discussing the different swallowing improvement surgeries. A manual search of references in selected articles and reviews was done as well. No chronologic limitation was set for the studies; however, only articles written in English and Japanese were considered. Due to the nature of this article, no particular inclusion or exclusion criteria were set when searching for studies to be used as references; however, all relevant studies were reviewed and agreed upon by the authors for inclusion in this review article. RESULTS/DISCUSSION: Surgeries to improve swallowing function can be categorized into those that reinforce nasopharyngeal closure or pharyngeal contraction, improve laryngeal elevation or pharyngoesophageal segment opening, and those that improve vocal fold closure to protect the airway during swallowing. They are an effective alternative treatment that may significantly improve these patients' quality of life. Swallowing rehabilitation with the altered pharyngolaryngeal structures is required post-operatively to significantly improve patients' dysphagia. CONCLUSIONS: Surgeries to improve swallowing function address specific dysfunctional sites involved in the swallowing mechanism. Choosing the most appropriate surgery for each patient requires knowledge of the pathophysiology for their dysphagia and detailed pre-operative work-up.

BACKGROUND/PURPOSE: Locally advanced tongue or tongue base cancer is recommended to be treated by radical resection that is usually detrimental to physiological functions. This study reports the efficacy and treatment outcome of the patients who had received total glossectomy and laryngeal suspension without lip-split mandibulotomy and free flap reconstruction to preserve laryngopharyngeal function. METHODS: From 2010 to 2018, 37 consecutive patients who had received the surgery were retrospectively recruited. RESULTS: The overall five-year survival is 72%. The postoperative dependent rate of feeding tube and tracheostomy largely decreases within 1-year follow-up. Treated by this surgical method, these patients are free from facial disfiguration, donor site morbidity, and destructive mastication and occlusion. It is also feasible to perform this surgical technique in the recurrent cases previously treated by chemoradiation. CONCLUSION: Total glossectomy with laryngeal suspension can be successfully applied to locally advanced tongue or tongue base cancer, and benefits the patients with improved survival and preserved physiological function. Especially surgeons for free flap reconstruction are understaffed at some regional or district hospitals.

PURPOSE: In this article, a simple, new laryngeal suspension procedure is described. The effect of hyoid bone suspension by suturing the digastric muscle to the periosteum of the mandible is analyzed. MATERIALS AND METHODS: To elucidate the effect of hyoid bone suspension, CT scans of 26 patients who underwent ipsilateral neck dissection with primary resection of tongue cancer were retrospectively reviewed, and the distance between the hyoid bone and the mandible was measured on the operated and unoperated sides of the neck. A total of 14 patients who underwent suturing of the digastric muscle to the mandible (digastric muscle-sutured group) and the 12 patients who did not (control group) were compared. RESULTS: In the digastric muscle-sutured group, the average distance between the hyoid bone and the mandible was significantly smaller on the operated side (17.8⯱â¯0.57â¯mm) than on the unoperated side (19.8⯱â¯0.93â¯mm; pâ¯<â¯0.05). In the control group, there was no significant difference between the operated side (21.0⯱â¯1.42â¯mm) and the unoperated side (19.7⯱â¯1.39â¯mm). The difference in the distance between the operated and unoperated sides was significantly larger in the digastric muscle-sutured group (1.97⯱â¯0.79â¯mm) than in the control group (-1.32⯱â¯0.61; pâ¯<â¯0.05). CONCLUSIONS: It was shown for the first time that suturing of the digastric muscle to the periosteum of the mandible in neck dissection with primary resection of tongue cancer resulted in hyoid bone suspension. This simple procedure can be useful for laryngeal suspension.

Supracricoid hemilaryngopharyngectomy (SCHLP) is a laryngeal preservation surgery for hypopharyngeal carcinoma confined to the pyriform sinus or laryngeal carcinoma with arytenoid infiltration. Postoperative dysphagia is inevitable, but both voice and swallowing functions can be preserved. Here, we present a case of severe dysphagia secondary to unexpected postoperative tissue loss and scarring. A 67-year-old man underwent left SCHLP for hypopharyngeal cancer, and on the third postoperative day, he developed necrotizing fasciitis of the left neck. He was unable to swallow and was transferred to a rehabilitation hospital 90 days after the surgery. Six months after surgery, the patient had significant glottic insufficiency due to laryngeal deformity, constant massive salivary aspiration, and difficulty releasing the cuffed cannula. Severe dysphagia due to glottic insufficiency and laryngeal elevation insufficiency due to scar formation were considered, and laryngoplasty and laryngeal suspension surgery using costal cartilage were performed on the 221st postoperative day. After the reoperation, he was able to wear a speech valve and could speak and spit out, although his glottis was still closed. On the 70th day after the reoperation, he was able to consume three meals of an oral dysphagia diet and was discharged home.

INTRODUCTION: Sarcopenic dysphasia is a relatively new disease concept describing impairments in swallowing resulting from a generalized loss of skeletal muscle mass. PRESENTATION OF CASE: In this case report, we describe the clinical history and presentation of a 76-year-old man who developed mild sarcopenic dysphasia following a period of physical inactivity after spinal stenosis surgery, which resulted in a loss of 10 kg of body weight in the 10-month period after surgery. The patient's dysphasia was managed with laryngeal suspension, performed via a minimally invasive thyromandibulopexy, in combination with rehabilitation and nutritional support. After a brief period of postoperative rehabilitation, the patient was able to eat soft meals on postoperative day 14, and a regular meal on postoperative day 18, without aspiration. We include a brief description of our surgical technique in the case report. DISCUSSION: Laryngeal suspension compensated for a decreased functional capacity of the swallowing muscles, with postoperative rehabilitation improving the strength of the swallowing muscles. Fixation of the thyroid cartilage to the mandible compensated for insufficient opening of the esophageal orifice, decreasing the pyriform sinus residue. Drawing of the thyroid cartilage in an anterosuperior position improved the anterosuperior position of the epiglottis, shortening the distance between the epiglottis and the base of the tongue, which narrowed the vallecula space and decreased vallecular residue. CONCLUSION: Based on our experience, laryngeal suspension, via minimally invasive thyromandibulopexy, could be considered to improve the outcomes of sarcopenic dysphagia, with an earlier return to eating normal meals.
RESUMO
OBJECTIVE: The purpose of this prospective study was to identify preoperative predictors of unstable exposure of vocal folds with focus on the anterior commissure (AC) prior to Laryngeal Microscopic Surgery. METHODS AND MATERIALS: Patients were classified into four groups based on the degree of AC exposure during Laryngeal Microscopic Surgery, and for the analysis, these groups were subdivided into unstable exposure and stable exposure subgroups depending on whether external manipulation was required to achieve AC exposure. Correlation of the degree of AC exposure with demographics, physical measurements, and anatomical measurements taken using landmarks in simple radiograph were evaluated. Receiver operating characteristic curve analysis was used to determine optimal cutoff values to predict unstable AC exposure. RESULTS: Fifty-nine patients were included in the analyses. Thyroid-mandible angle (TMA) in the extended position, thyroid-mental distance (TMD) ratio, and TMA difference in the neutral and extended positions were significantly correlated with the degree of AC exposure. However, only a TMD ratio of <1.25 reliably predicted unstable AC exposure. CONCLUSIONS: TMD ratio of <1.25 reliably predicted unstable AC exposure. If there is no increase of the distance between the thyroid notch and the mental prominence (TMD) more than 25% on neck extension, the probability of getting stable exposure of the anterior commissure is low.

OBJECTIVES: Surgical procedure is considered in patients with severe dysphagia when conservative treatment fails. This study aimed to evaluate laryngeal suspension (LS) and upper esophageal sphincter (UES) myotomy for treating severe dysphagia due to brain disease. METHODS: Fourteen patients underwent LS and UES myotomy, with a median follow-up of 5 years and 6 months when conservative treatment failed. The penetration-aspiration scale (PAS), the Dysphagia Severity Scale (DSS), the Eating Status Scale (ESS), and diet contents were evaluated just before surgery, at discharge, and at the last follow-up. RESULTS: Preoperative intake was tube feeding in all patients. The patients learned the extended head and flexed neck posture to open the esophageal inlet. PAS, DSS and ESS scores, and diet contents were significantly improved at discharge compared with before surgery, and were maintained until the last follow-up. Eight patients had pneumonia during their hospital stay, and five had pneumonia between discharge and at the last follow-up. Age was significantly, negatively correlated with DSS and ESS at the last follow-up. CONCLUSION: Although LS and UES myotomy require a long inpatient rehabilitation and the risk of pneumonia after surgery is high, the outcome is favorable and the effects last for a long time.

OBJECTIVES/HYPOTHESIS: To evaluate the efficacy of various techniques of laryngohyoid suspension in the elimination of aspiration utilizing a cadaveric ovine model of profound oropharyngeal dysphagia. STUDY DESIGN: Animal study. METHODS: The head and neck of a Dorper cross ewe was placed in the lateral fluoroscopic view. Five conditions were tested: baseline, thyroid cartilage to hyoid approximation (THA), thyroid cartilage to hyoid to mandible (laryngohyoid) suspension (LHS), LHS with cricopharyngeus muscle myotomy (LHS-CPM), and cricopharyngeus muscle myotomy (CPM) alone. Five 20-mL trials of barium sulfate were delivered into the oropharynx under fluoroscopy for each condition. Outcome measures included the penetration aspiration scale (PAS) and the National Institutes of Health (NIH) Swallow Safety Scale (NIH-SSS). RESULTS: Median baseline PAS and NIH-SSS scores were 8 and 6, respectively, indicating severe impairment. THA scores were not improved from baseline. LHS alone reduced the PAS to 1 (P = .025) and NIH-SSS to 2 (P = .025) from baseline. LHS-CPM reduced the PAS to 1 (P = .025) and NIH-SSS to 0 (P = .025) from baseline. CPM alone did not improve scores. LHS-CPM displayed improved NIH-SSS over LHS alone (P = .003). CONCLUSIONS: This cadaveric model represents end-stage profound oropharyngeal dysphagia such as what could result from severe neurological insult. CPM alone failed to improve fluoroscopic outcomes in this model. Thyrohyoid approximation also failed to improve outcomes. LHS significantly improved both PAS and NIH-SSS. The addition of CPM to LHS resulted in improvement over suspension alone. LEVEL OF EVIDENCE: NA. Laryngoscope, 127:E422-E427, 2017.
