The Role of the Modified Barium Swallow Study and Esophagram in Patients with Globus Sensation.

Globus sensation (GS) is a common benign finding that is often associated with frequent throat clearing and is commonly a result of laryngopharyngeal reflux. The primary objective of this investigation was to examine the role of the modified barium swallow study (MBSS) with esophagram in the diagnosis and management patients who present with chief complaints of a GS. We hypothesize that these radiographic swallow studies do not add clinically significant information in the investigation of this common complaint. Retrospective chart review of patients with chief complaints of GS between 2000 and 2009 who underwent both MBSS and esophagram was conducted. Of the 380 patients who underwent MBSS, only 68 patients were eligible for this study. Over 70 % of patients were on reflux medicines, 81 % of the MBSS studies were normal, 62 % of the esophagram results were normal, 18 % of patients had a hiatal hernia, and 10 % exhibited signs of reflux. Esophagoscopy was performed in 45 % of patients, of which 35 % were normal. One patient initially had a normal esophagogastroduodenoscopy and then was subsequently diagnosed with gastric CA. Fifty-nine percent of patients underwent CT Neck with IV contrast, of which 67 % had minor findings. Positive findings are often benign and can be treated with reflux medications. Esophagoscopy was often normal and most sensitive only for hiatal hernia. No hypopharyngeal cancer was noted. Therefore, MBSS and esophagram for patients with GS are most often negative and fail to add significant diagnostic information.

Influence of consonant voicing characteristics on sentence production in abductor versus adductor spasmodic dysphonia.

OBJECTIVES/HYPOTHESIS: This study evaluated the hypotheses that sentence production by speakers with adductor (AD) and abductor (AB) spasmodic dysphonia (SD) may be differentially influenced by consonant voicing and manner features, in comparison with healthy, matched, nondysphonic controls. STUDY DESIGN: This was a prospective, single blind study, using a between-groups, repeated measures design for the independent variables of perceived voice quality and sentence duration. METHODS: Sixteen subjects with ADSD and 10 subjects with ABSD, as well as 26 matched healthy controls produced four short, simple sentences that were systematically loaded with voiced or voiceless consonants of either obstruant or continuant manner categories. Experienced voice clinicians, who were "blind" as to speakers' group affixations, used visual analog scaling to judge the overall voice quality of each sentence. Acoustic sentence durations were also measured. RESULTS: Speakers with ABSD or ADSD demonstrated significantly poorer than normal voice quality on all sentences. Speakers with ABSD exhibited longer than normal duration for voiceless consonant sentences. Speakers with ADSD had poorer voice quality for voiced than for voiceless consonant sentences. Speakers with ABSD had longer durations for voiceless than for voiced consonant sentences. CONCLUSIONS: The two subtypes of SD exhibit differential performance on the basis of consonant voicing in short, simple sentences; however, each subgroup manifested voicing-related differences on a different variable (voice quality vs sentence duration). Findings suggest different underlying pathophysiological mechanisms for ABSD and ADSD. Findings also support inclusion of short, simple sentences containing voiced or voiceless consonants as part of the diagnostic protocol for SD, with measurement of sentence duration in addition to judments of voice quality severity.

Conservative management of iatrogenic esophageal perforation in head and neck cancer patients with esophageal stricture.

OBJECTIVE: Evaluate the efficacy of conservative management of iatrogenic esophageal perforation following dilatation of a stricture secondary to the treatment of head and neck cancer. STUDY DESIGN: Case series with chart review. SUBJECTS AND METHODS: Retrospective chart review of 24 patients with esophageal perforation treated at the Detroit Medical Center from 1999 to 2008. Of these, eight head and neck cancer patients had esophageal stricture and underwent dilatation with subsequent esophageal perforation. RESULTS: Six patients were managed conservatively; two were managed surgically. All eight patients had radiation, six had chemotherapy, and five had surgery as part of their oncologic treatment. Stricture site was at the cricopharyngeus or neopharynx. Perforation size was estimated at 3 to 7 mm in conservative patients and approximately 10 mm in surgical patients. All patients survived to be discharged from the hospital and diet was tube feeds. CONCLUSION: In head and neck cancer patients with post-treatment esophageal stricture, iatrogenic cervical esophageal perforations can often be safely managed conservatively. The criteria are: prompt diagnosis within one hour, small perforation (3-7 mm), penetrating type of perforation with circumferential mucosal contact, proximal or cervical esophageal location, and stabilization and improvement of clinical signs and symptoms for 24 hours after initial ICU management.

Effects of sequential Dermatophagoides pteronyssinus antigen stimulation on anatomy and physiology of the larynx.

The goal of this investigation was to study the effects of sequential dust mite antigen stimulation on the appearance and function of the larynx. To that end, we designed a randomized, placebo-controlled, double-blind, prospective analysis of adults who had tested positive for perennial dust mite allergy. The larynx of patients who received the active antigen was challenged directly with a low (1:100) and a high (1:40) concentration of the dust mite allergen via an oral nebulizer. Voice laboratory assessment tools included voice and allergy questionnaires, videostroboscopic examination of the larynx, acoustic and speech aerodynamic analyses, and digital audio voice recordings. The study was prematurely terminated after 2 patients had been treated with the highest concentration of the antigenic suspension because of adverse effects, including chest tightness, coughing, and voice difficulties. Both of these patients had demonstrated viscous endolaryngeal secretions and vocal fold edema on videostroboscopy. No reactions were noted at the lower concentration of antigen exposure or in 1 control patient who completed the study. We believe that our findings, as preliminary as they are, may serve as an initial template for the differential diagnosis and treatment of other patients with inhalant allergies who present with chief complaints suggestive of allergic laryngitis.

Baseline laryngeal effects among individuals with dust mite allergy.

OBJECTIVE: To examine baseline effects of perennial allergy on laryngeal appearance, laryngeal function, and perceived vocal handicap among individuals without current allergy or voice symptoms. DATA SOURCES: This pilot study included 47 adults: 21 with positive and 26 with negative skin test responses for the dust mite, Dermatophagoides pteronyssinus. METHODS: Subjects were tested for sensitivity to dust mite antigen by prick testing. Laryngeal appearance and function were studied with laryngovideostroboscopy, acoustic and speech aerodynamic analysis, and voice sampling. These parameters were blindly analyzed by three trained examiners. Subjects also completed the Voice Handicap Index (VHI) as a measure of vocal handicap. RESULTS: Subjects allergic to dust mites perceived significantly greater vocal handicap on the VHI than did nonallergic subjects. No significant differences were noted between groups in laryngeal appearance or function. CONCLUSION: These pilot data suggest that, at baseline, allergic individuals perceive greater vocal handicap than their nonallergic counterparts (P = 0.04), even in the absence of current allergy symptoms or observable physical or functional abnormalities. These preliminary observations can serve as an impetus for further research into this important area, including the potential interrelationship between acid reflux disease and allergic laryngeal inflammation.

Cymetra injection for unilateral vocal fold paralysis.

Cymetra has shown excellent tissue biocompatibility, a low rate of resorption, and no tissue reactivity when injected for treatment of facial wrinkling. On the basis of these findings, we hypothesize that injection of Cymetra into the thyroarytenoid muscle for treatment of glottal incompetence may demonstrate similar findings and lead to long-term improvement in voice quality and glottal gap closure. Ten patients with breathy dysphonia caused by unilateral vocal fold paralysis underwent transoral injection of Cymetra into the thyroarytenoid muscle. Each subject underwent preoperative and postoperative acoustic analysis, aerodynamic measures, taped voice sampling, and videostroboscopy. Significant improvements were identified in maximum phonation time, relative glottal area, and subjective judgment of glottal competency. These results were not maintained at the 3-month study interval. No significant change in quantitative or subjective voice quality was noted for the study group during the investigation. Resorption of Cymetra may play a significant role in contributing to these findings.

Laryngeal effects of antigen stimulation challenge with perennial allergen Dermatophagoides pteronyssinus.

OBJECTIVE: We conducted a pilot study to assess the effects of antigen stimulation on the appearance and function of the larynx. STUDY DESIGN AND SUBJECTS: The prospective, double-blind, randomized study included 9 adult patients with a skin-prick test positive for Dermatophagoides pteronyssinus. MAIN OUTCOME MEASURES: Subjects were blindly challenged via nebulizer with either an active antigenic suspension or placebo. Baseline and 30-minute evaluations of the larynx were performed. Assessments included subjective voice and videostroboscopic assessments, acoustic analysis of voice, speech aerodynamic testing, and allergy and voice handicap questionnaires. RESULTS: Although both inflammation and increased mucus were noted, there were no significant differences between the antigen- and placebo-exposed subjects on any of the measures obtained. CONCLUSIONS: Our preliminary investigation was not successful in demonstrating a direct causal relationship between antigen exposure and physical or functional changes in the larynx. Future studies will involve modifications to our current methodology, including increasing the concentration of antigen, prolonging the exposure time, and observing for late phase responses.

Fiberoptic examination of the pharyngoesophageal segment in tracheoesophageal speakers.

OBJECTIVE: To describe a novel use of flexible fiberoptic endoscopy to examine the pharyngoesophageal segment, upper esophagus, and distal end of the tracheoesophageal prosthesis in patients who have undergone a total laryngectomy and a tracheoesophageal puncture. METHODS: Five patients with poor-quality or no tracheoesophageal voice were evaluated by a speech pathologist and an otolaryngologist. A flexible endoscope interfaced with a video monitoring device was introduced transnasally and passed through the pharyngoesophageal segment. Examination of the anatomical relationship between the prosthesis and the esophageal mucosa was conducted while the subjects attempted to phonate. Treatments were then initiated based on the endoscopic findings. CONCLUSION: Flexible endoscopy is a safe, cost-effective, diagnostic tool for evaluating laryngectomees suffering from poor-quality tracheoesophageal voice.
