The effect of vocal fold medialization (VFM) on vocal improvement in persons with unilateral vocal fold immobility (UVFI) is well established. The effect of VFM on the symptom of dysphagia is ...uncertain. The purpose of this study is to evaluate dysphagia symptoms in patients with UVFI pre- and post-VFM.
Case series with chart review.
Academic tertiary care medical center.
The charts of 44 persons with UVFI who underwent VFM between June 1, 2013, and December 31, 2014, were abstracted from a prospectively maintained database at the University of California, Davis, Voice and Swallowing Center. Patient demographics, indications, and type of surgical procedure were recorded. Self-reported swallowing impairment was assessed with the validated 10-item Eating Assessment Tool (EAT-10) before and after surgery. A paired samples t test was used to compare pre- and postmedialization EAT-10 scores.
Forty-four patients met criteria and underwent either vocal fold injection (73%) or thyroplasty (27%). Etiologies of vocal fold paralysis were iatrogenic (55%), idiopathic (29%), benign or malignant neoplastic (9%), traumatic (5%), or related to the late effects of radiation (2%). EAT-10 (mean ± SD) scores improved from 12.2 ± 11.1 to 7.7 ± 7.2 after medialization (P < .01) with a follow-up of 119 ± 65 days.
Patients with UVFI suffer from dysphagia and report significant improvement in swallowing symptoms following VFM. The symptomatic improvement appears to be durable over time.

Recurrent respiratory papillomatosis (RRP) is a rare, benign disease with no known cure. RRP is caused by infection of the upper aerodigestive tract with the human papillomavirus (HPV). Passage ...through the birth canal is thought to be the initial transmission event, but infection may occur in utero. HPV vaccines have helped to provide protection from cervical cancer; however, their role in the prevention of RRP is undetermined. Clinical presentation of initial symptoms of RRP may be subtle. RRP course varies, and current management focuses on surgical debulking of papillomatous lesions with or without concurrent adjuvant therapy.

Extraesophageal reflux disease, commonly called laryngopharyngeal reflux disease (LPRD), continues to be an entity with more questions than answers. Although the role of LPRD has been implicated in ...various pediatric diseases, it has been inadequately studied in others. LPRD is believed to contribute to failure to thrive, laryngomalacia, recurrent respiratory papillomatosis, chronic cough, hoarseness, esophagitis, and aspiration among other pathologies. Thus, LPRD should be considered as a chronic disease with a variety of presentations. High clinical suspicion along with consultation with an otolaryngologist, who can evaluate for laryngeal findings, is necessary to accurately diagnose LPRD.
Objective
Endoscopic Zenker diverticulotomy (EZD) is a primary treatment for Zenker diverticulum (ZD). During EZD, the diverticulum is not excised, and interpretation of postoperative ...videofluoroscopic swallow study (VFSS) is challenging. The purpose of this investigation was to describe normal VFSS findings status post‐successful EZD.
Methods
The charts of all patients with ZD treated at our center between October 01, 2011, and May 30, 2014, were ed. Outcome measures included recidivistic diverticulum size, Eating Assessment Tool‐10 (EAT‐10), penetration aspiration scale, pharyngeal constriction ratio (PCR), and pharyngoesophageal segment (PES) opening.
Results
Twenty patients met inclusion criteria. The mean age was 70.5 (± 13) years. Seventy percent of the patients were male. Mean EAT‐10 decreased 72.1% from 17.9 (± 8.2) to 5 (± 6.9) (P < 0.0001), and diverticulum size decreased 50.9% from 1.96 cm (± 0.68) to 0.96 cm (± 0.57) (P < 0.001). The PCR improved 33.6% from 0.17 (± 0.13) to 0.11 (± 0.11) (P < 0.001). Mean PES opening increased 61.6% from 0.53 cm (± 0.3544) to 0.86 cm (± 0.29) in lateral view and increased 40.0% from 1.00 cm (± 0.54) to 1.39 cm (± 0.46) in anteroposterior view (P < 0.001).
Conclusion
VFSS following successful EZD demonstrates an approximate 50% reduction in diverticulum size and significant improvement in PCR and PES opening. These data provide a framework for the expected fluoroscopic outcomes of successful diverticulotomy.

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.

Abstract Objective Tonsillectomy is a common procedure performed in children with the main complication being post-operative hemorrhage. It is uncertain if patients with hematological abnormalities ...face a higher risk of post-operative hemorrhage. Study design Retrospective chart review. Setting Tertiary referral hospital. Patients selected All patients with a known hematologic disorder as well as children without a hematologic abnormality undergoing tonsillectomy with or without adenoidectomy in the past two years at our institution were included in this study. Main outcome measure We sought to determine whether children with hematologic disorders are at an increased risk of post-operative hemorrhage after surgery. Results Four-hundred and sixty-two patients were identified who underwent a tonsillectomy during this time period. Fourteen patients with hematological abnormalities were identified with only one patient suffering a post-tonsillectomy hemorrhage. All patients with abnormal laboratory values prior surgery underwent medical treatment in conjunction with pediatric hematology and did not suffer a post-tonsillectomy hemorrhage. Despite a small study group, the low incidence (1/14) of post-tonsillectomy hemorrhage in patients with hematological abnormalities suggests that these patients may not be at an increased risk, especially if appropriately evaluated and treated pre-operatively. Conclusion Despite small sample size the results of our study suggest that patients with coagulation disorders may not have an increased risk of post-tonsillectomy hemorrhage when evaluated and corrected pre-operatively.

We conducted a retrospective review to identify the characteristics of cerebrospinal fluid (CSF) leak in patients who had undergone septoplasty and in selected patients who had experienced a ...spontaneous CSF leak. CSF leak is a known but infrequently reported complication of septoplasty; to the best of our knowledge, only 4 cases have been previously published in the literature. A review of our institutions database revealed 3 cases of postseptoplasty CSF leak. We reviewed all the available data to look for any commonalities among these 7 cases. In addition, we reviewed 6 cases of spontaneous CSF leak selected from our database for the same purpose. For all patients, we noted the side of the cribriform plate defect, its size and, for the postseptoplasty cases, the interval between the septoplasty and the leak repair. Overall, we found that leaks were much more common on the right side than on the left. The sizes of the leaks in the 2 postseptoplasty groups were comparable (mean: 14.0 × 6.4 mm). The interval between septoplasty and leak repair ranged from 2.5 to 20 years in our cases and from 3 days to 22 weeks in the previously published cases. All 3 of the postseptoplasty patients in our database presented with clear rhinorrhea. Two of the 3 patients had meningitis; 1 of these 2 also had pneumocephalus. Of the 6 cases of spontaneous CSF leaks, 4 occurred on the right and 2 on the left; the average size of the defect was 5.8 mm in the greatest dimension. The finding that cribriform plate defects after septoplasty were typically right-sided likely reflects the prevalence of left-sided surgical approaches. Also, the fact that the defects were larger in the postseptoplasty cases than in the spontaneous cases is likely attributable to the torque effect toward the thin skull base that occurs when the perpendicular plate is twisted during septoplasty.
Objectives/Hypothesis:
Botulinum toxin (Botox) injections into the thyroarytenoid muscles are the current standard of care for adductor spasmodic dysphonia (ADSD). Reported adverse effects include a ...period of breathiness, throat pain, and difficulty with swallowing liquids. Here we report multiple cases of bilateral abductor paralysis following Botox injections for ADSD, a complication previously unreported.
Study Design:
Retrospective case series.
Methods:
Patients that received Botox injections for spasmodic dysphonia between January 2000 and October 2009 were evaluated. Patients with ADSD were identified. The number of treatments received and adverse effects were noted. For patients with bilateral abductor paralysis, age, sex, paralytic Botox dose, prior Botox dose, and course following paralysis were noted.
Results:
From a database of 452 patients receiving Botox, 352 patients had been diagnosed with ADSD. Of these 352 patients, eight patients suffered bilateral abductor paralysis, and two suffered this complication twice. All affected patients were females over the age of 50 years. Most patients had received treatments prior to abductor paralysis and continued receiving after paralysis. Seven patients recovered after a brief period of activity restrictions, and one underwent a tracheotomy. The incidence of abductor paralysis after Botox injection for ADSD was 0.34%.
Conclusions:
Bilateral abductor paralysis is a rare complication of Botox injections for ADSD, causing difficulty with breathing upon exertion. The likely mechanism of paralysis is diffusion of Botox around the muscular process of the arytenoid to the posterior cricoarytenoid muscles. The paralysis is temporary, and watchful waiting with restriction of activity is the recommended management. Laryngoscope, 2010

Dysphagia is a common symptom affecting many patients with several different causes. The use of thin, distal-chip, video esophagoscopes allows for a thorough evaluation and management of dysphagia in ...the office. Esophagitis should be recognized on endoscopy in addition to webs, rings, and strictures. Procedures to treat the cause of dysphagia can be performed in clinic with the use of topical anesthesia. Descriptions of how to perform procedures for dysphagia, including vocal fold medialization, diagnostic esophagoscopy, and esophageal procedures for intervention are reviewed.
