Epiglottic carcinoma as a cause of laryngeal penetration and aspiration

OBJECTIVE. The purpose of our investigation was to review a series of patients with epiglottic carcinoma to elucidate the clinical and videofluoroscopic findings in these individuals. CONCLUSION. Patients with epiglottic carcinoma often present with symptoms of aspiration or pharyngeal dysphagia of relatively brief duration in the absence of a preexisting neurologic disease. In this clinical setting, barium studies are useful not only for detecting the epiglottic carcinoma but also for delineating the presence and mechanism of laryngeal penetration or tracheobronchial aspiration.     

Swallowing abnormalities in multiple sclerosis: correlation between videofluoroscopy and subjective symptoms

Cartilage degenerative diseases, such as osteoarthritis, affect million of people. Magnetic resonance imaging is presently the most accurate imaging modality in evaluating the state of hyaline cartilage; however, clinical MRI does not accurately reveal early degenerative alterations in cartilage, due mainly to low spatial resolution. Magnetic resonance microscopy (MRM, or μMRI) appears exceptionally well suited to the in vitro or ex vivo study of this heterogeneous tissue, due to its high spatial resolution; however, despite this, further studies are necessary to evaluate the potential of MRM in the detection of early cartilage damage. Herein we briefly review the current applications of MRM in the study of hyaline cartilage. In particular, we review the MR appearance of hyaline cartilage on high-resolution images, the different MRM techniques used to image normal and enzymatically or chemically degraded cartilage and the potential use of contrast agents. The future directions and the relevance of MRM findings for a better understanding of cartilage physiology in health and disease are also discussed. Electronic Publication     

Complications after laryngeal surgery: videofluoroscopic evaluation of 120 patients

AIM: Videofluoroscopic assessment of the spectrum and incidence of swallowing complications after state-of-the-art laryngeal cancer surgery. MATERIALS AND METHODS: We retrospectively studied videofluoroscopic examinations of 120 patients (94 men, 26 women; mean age, 58 years) with suspected complications after laryngeal resection (partial laryngectomy, 65; total laryngectomy, 55). Swallowing function (i.e., oral bolus control, laryngeal elevation and closure, presence of pharyngeal residue, aspiration) and structural abnormalities such as strictures, fistulas and tumour recurrence were assessed by videofluoroscopy. RESULTS: Abnormalities were found in 110 patients, including strictures in nine, fistulas in six and mass lesions in 13 patients. Aspiration was found in 63 patients overall (partial laryngectomy, 61/65; total laryngectomy, 2/55), occurring before swallowing in five, during swallowing in 34, after swallowing in nine and at more than one phase in 15 patients. Pharyngeal paresis was detected in three and pharyngeal weakness in 19 patients. Pharyngo-oesophageal sphincter dysfunction was observed in 10 cases. CONCLUSION: Aspiration is a very common complication after partial laryngeal resection. It is mainly caused by incomplete laryngeal closure, sphincter dysfunction or pharyngeal pooling. Videofluoroscopy is the only radiological technique able to identify both disordered swallowing function and structural changes after laryngeal resection. Detection of these complications is crucial for appropriate further therapy.Kreuzer, S. H. (2000). Clinical Radiology55, 775-781.     

Oropharynx in patients with cerebrovascular disease: evaluation with videofluoroscopy

Forty-six patients with cerebrovascular disease underwent videofluoroscopic examination of the oropharynx to assess location and severity of swallowing dysfunction with use of boluses of various consistencies. Low- and high-viscosity barium suspensions, a barium paste, and a paste-coated cookie were used; not all patients were given all materials. Thirty-nine patients had abnormalities of both oral and pharyngeal function. Two patients had oral dysfunction only, and five had pharyngeal abnormalities only. Mild swallowing difficulties occurred in 18 patients (39%), moderate dysfunction in 23 (50%), and severe dysfunction in five (11%). Thirty-one patients had pharyngeal stasis, which was symmetric in 25 patients (81%), right-sided in three, and left-sided in three. Asymmetric stasis did not correlate to the site of cerebrovascular disease. Twenty-four episodes of aspiration occurred, half of them with the low-viscosity barium suspension. Thus, video-fluoroscopy can be used to define the location and severity of oropharyngeal abnormalities, which is critical for feeding recommendations. The abnormalities present, however, were not useful in predicting the type of cerebrovascular disease.     

Defective closure of the laryngeal vestibule: frequency of pulmonary complications

Aspiration and its potential complications, bronchopneumonia and other pulmonary diseases, were studied in 67 fully conscious and mobile patients with cineradiographically verified dysfunction of swallowing. They were compared to a group of 67 patients of similar age with normal swallowing. Bronchopneumonia was found in nine (13%) of the patients with aspiration compared to two (3%) of the patients without (p = 0.05). Chronic pulmonary disease was more frequently observed in patients with aspiration than in those without, seven (10%) and one (1.5%), respectively (p = 0.03). Even though pulmonary complications of defective closure of the laryngeal vestibule are not frequent, swallowing training for fully conscious and relatively mobile patients would seem desirable.     

Videofluoroscopy of swallowing in symptomatic patients who have undergone long-term intubation

OBJECTIVE: The aim of this study was to evaluate whether specific patterns of swallowing dysfunction occur in symptomatic patients after long-term intubation. SUBJECTS AND METHODS: Twenty-one patients (16 men, five women; mean age, 66 years) who presented with clinical signs of aspiration after long-term intubation (mean duration, 24.6 days) underwent videofluoroscopy. They were analyzed for functional abnormalities of the tongue, soft palate, epiglottis, hyoid and larynx, pharynx, and the upper esophageal sphincter. We assessed the presence or absence of aspiration, the type of aspiration (pre-, intra-, and postdeglutitive), and a spectrum of other swallowing abnormalities. RESULTS: There were 18 patients (86%) with radiologically proven aspiration. In another patient only laryngeal penetration occurred. There were 11 combinations of pre-, intra-, and postdeglutitive aspiration. Predeglutitive aspiration was predominant and present in 52% of our patients. We found functional abnormalities of the tongue in 48%, of the soft palate in 10%, of the epiglottis in 48%, of the pharynx in 71%, and of the upper esophageal sphincter in 24%. CONCLUSION: Patients who are symptomatic after undergoing long-term intubation do not develop a specific type or pattern of swallowing dysfunction or aspiration, but show a large variety of aspiration types and associated swallowing disorders. Nevertheless, videofluoroscopy has the ability to reveal complex deglutition disorders and to aid precise planning of individualized functional swallowing therapy.     

Videofluoroscopic evaluation of complications after laryngeal resection

Summary In past decades, the surgical techniques for treating laryngeal carcinoma have been vastly improved. For circumscribed tumors, voice-conserving resections are possible and for extensive neoplasms, radical laryngectomy, sometimes combined with chemoradiation, has been developed. Postoperative complications regarding swallowing function are not uncommon. Radiologic examinations, especially pharyngography and videofluoroscopy, are most often used to evaluate patients with complications after laryngeal surgery. An optimized videofluoroscopic technique for evaluation of complications is described. The radiologic appearance of early and late complications, such as fistulas, hematomas, aspiration, strictures, dysfunction of the pharyngoesophageal sphincter, tumor recurrence, and metachronous tumors is demonstrated.      

Radiographic findings and complications after surgical or endoscopic repair of Zenker's diverticulum in 16 patients

OBJECTIVE: The purpose of our study was to reassess the radiographic findings and complications associated with surgical or endoscopic repair of Zenker's diverticulum. MATERIALS AND METHODS: Sixteen patients who underwent various procedures for repair of Zenker's diverticulum (diverticulectomy and cricopharyngeal myotomy in [n = 8], diverticulopexy and cricopharyngeal myotomy [n = 4], endoscopic stapling diverticulotomy [n = 3], and cricopharyngeal myotomy alone [n = 1]) had radiographic studies with water-soluble contrast material, barium, or both during the early postoperative period (n = 7), late postoperative period (n = 4), or both (n = 5). The radiologic reports and images were reviewed to determine the postoperative findings and complications associated with surgical or endoscopic repair of Zenker's diverticulum. RESULTS: Radiographic studies revealed leaks during the early postoperative period in three (27%) of 11 patients after surgical repair of Zenker's diverticulum and in zero of three patients after endoscopic diverticulotomy. Pharyngeal dysfunction (pharyngeal paresis, decreased epiglottic tilt, laryngeal penetration, or tracheobronchial aspiration) was detected in seven (54%) of 13 patients after surgery and in one (33%) of three patients after endoscopic diverticulotomy; five of these eight patients had follow-up barium studies during the late postoperative period, and all five showed marked improvement in pharyngeal function. An extrinsic cricopharyngeal impression was detected in six (38%) of these 16 patients, a remnant diverticulum in four (25%), and mucosal beaking in three (19%). A suspended or inverted diverticulum was detected in one of the four patients who underwent surgical diverticulopexy. CONCLUSION: Radiologists should be aware of the various postoperative findings and complications associated with surgical or endoscopic repair of Zenker's diverticulum so that appropriate interventions can be taken in patients with this condition.     

Functional lesions in dysphagia due to acute stroke: discordance between abnormal findings of bedside swallowing assessment and aspiration on videofluorography

Introduction

Bedside swallowing assessments are often used to assess dysphagia. However, in some patients, aspiration pneumonia occurs without any problems on bedside swallowing assessments and some patients do not suffer aspiration pneumonia despite abnormal results of bedside swallowing assessments in acute stroke. To detect the differences of lesions related to bedside swallowing assessment abnormality and aspiration, we investigated swallowing-related functional lesions in terms of cerebral blood flow in patients with dysphagia after stroke.

Methods

The study included 50 acute stroke patients who underwent bedside swallowing assessments and videofluorography as well as single-photon emission computed tomography (CT) at approximately the same time. Bedside swallowing assessments included repetitive saliva swallowing test and modified water swallowing test as dry and wet swallowing tasks. The presence or absence of aspiration was assessed using videofluorography. We divided patients into three subgroups based on the outcomes of the bedside swallowing assessments and presence or absence of aspiration. Statistical image analysis was performed using single-photon emission CT to determine their relationship with bedside swallowing assessments and videofluorography results.

Results

Twenty-seven (54.0 %) and 28 (56.0 %) patients had abnormal repetitive saliva swallowing test and modified water swallowing test results. Videofluorography indicated aspiration in 35 (70.0 %) patients. In comparing patients with and without abnormal results on each test, the groups with abnormal repetitive saliva swallowing test, abnormal modified water swallowing test, and aspiration demonstrated lower cerebral blood flow in the left precuneus, left insula, and anterior cingulate gyrus, respectively.

Conclusions

Based on the analysis of cerebral blood flow, functional lesions differed across abnormal repetitive saliva swallowing test and abnormal modified water swallowing test findings and aspiration on videofluorography, and each test may assess different functions among the many processes involved in swallowing.     

Colonic interposition: radiographic evaluation

This report reviews the clinical and radiographic features of 40 patients who underwent visceral esophageal substitution with colon for benign or malignant lesions of the esophagus. The incidence and radiographic identification of complications are discussed. All patients were routinely examined with barium esophagrams on postoperative day 10. If an anastomotic leak was suspected clinically before this time, studies were performed using water-soluble iodinated contrast material. Follow-up barium esophagrams were obtained 1-96 months after operation (average, 60 months) in 24 patients. Eight patients (21%) demonstrated asymptomatic "jejunization" of the colonic mucosa with no attributable clinical manifestations; this finding resolved in 1-3 months, without sequelae, and has not been reported before. The spectrum of ischemic changes in the colonic segment included mucosal edema, spasm, ulceration, loss of haustration, and frank necrosis. Radiographically detectable early postoperative complications included anastomotic leak in six (three pharyngocolic, three cervical esophagocolic) and aspiration of barium into the tracheobronchial tree due to incoordinated swallowing in eight. Late postoperative complications included anastomotic narrowing (12) malfunctioning of the colon due to impaired emptying (five), recurrent aspiration pneumonia (three), small bowel obstruction (three), transhiatal herniation of small bowel through the diaphragmatic hiatus (one), and reflux into the retained bypassed esophagus (one).

Digital cineradiographic study of swallowing in patients with amyotrophic lateral sclerosis

PURPOSE: This study was performed to evaluate the usefulness of digital cineradiography in detecting swallowing disorders in dysphagic patients affected by amyotrophic lateral sclerosis (ALS) with a view to planning an adequate therapeutic approach. MATERIAL AND METHODS: From January 2005 to September 2006, 23 patients (10 men and 13 women; mean age 41.3+/-8.6 years) affected by ALS were evaluated with digital cineradiography to assess the grade of dysphagia. All patients were classified using the Hillel ALS Severity Scale (ALSSS). All examinations were performed with radiocontrolled equipment provided with a digital C-arm. RESULTS: The cineradiographic technique enabled us to differentiate patients with disorders of the oral (17/23) and/or pharyngeal (19/23) swallowing phase from those without swallowing dysfunction (4/23). In 14/23 patients, passage of contrast medium into the upper airways was observed during swallowing, whereas in 5/23 cases, aspiration of contrast medium into the lower airways was recorded. CONCLUSIONS: The videofluoroscopic swallowing study has high diagnostic capabilities in the evaluation of swallowing disorders, as it is able to identify the degree and causes of impairment. In addition, the study proved useful for planning speech therapy and for follow-up in patients with ALS.     

Videoradiographic analysis of how carbonated thin liquids and thickened liquids affect the physiology of swallowing in subjects with aspiration on thin liquids

PURPOSE: To analyze how carbonated thin liquids affected the physiology of swallowing in dysphagic patients. MATERIAL AND METHODS: 40 patients were analyzed; 36 were neurologically impaired. During a therapeutic videoradiographic swallowing examination the patients had to swallow liquids with the following consistencies three times: thin, thickened and carbonated. The liquids were given in doses of 3 x 5 ml. The swallows were analyzed regarding penetration/aspiration, pharyngeal transit time and pharyngeal retention. RESULTS: Significant difference was found regarding penetration/aspiration when comparisons were made between thin liquid and carbonated thin liquid (p<0.0001). Carbonated liquid reduced the penetration to the airways. The comparison between thin liquid and thickened liquid (p<0.0001) showed significant less penetration with thickened liquids. Pharyngeal transit time was reduced both when comparing thin liquid with thin carbonated liquid (p<0.0001) and thickened liquid (p<0.0001). Pharyngeal retention was significantly reduced (p<0.0001) with carbonated thin liquid compared to thickened liquid. The comparison of thin liquids and carbonated thin liquids showed p=0.0013, thin and thickened liquids p=0.0097. CONCLUSIONS: Carbonated liquids reduced penetration/aspiration into the airways, reduced pharyngeal retention and pharyngeal transit time became shorter. Therefore, carbonated liquids are a valuable treatment option for patients with penetration/aspiration. Thickened liquids may still be an option for patients who cannot tolerate carbonated liquids and liquids with this consistency are safer than thin liquids.     

Comparison between the radionuclide salivagram and videofluoroscopic swallowing study methods for evaluating patients with aspiration pneumonia

Objective

A videofluoroscopic swallowing study (VFSS) is generally used to assess dysphagia and aspiration, although false-negative results may be obtained. Saliva aspiration may cause false-negative VFSS findings in elderly people. A radionuclide salivagram can be useful in detecting saliva aspiration. We therefore compared these two methods for the evaluation of patients with aspiration pneumonia.

Methods

We prospectively enrolled 50 patients with aspiration pneumonia into this study. All patients underwent VFSS, and were evaluated on the Penetration-Aspiration Scale. A salivagram was performed on the day after VFSS and each patient received 1 mL Tc-99 m DTPA sublingually. Both dynamic and delayed images were obtained.

Results

Aspiration was observed in 34 % of patients by salivagram and in 42 % by VFSS. The frequency of tests that were positive for aspiration pneumonia using a combination of the two methods was 52 %. Five patients with positive aspiration findings on salivagram were negative on VFSS. The association between VFSS and salivagram findings was significant but the total agreement was 72 %. The frequency of aspiration pneumonia was significantly associated with an abnormal salivagram finding.

Conclusions

A salivagram may be a useful method for the evaluation of aspiration in elderly people, and a combination of the VFSS and salivagram methods could enable a more effective investigation of aspiration pneumonia.     

Videofluoroscopy of swallowing abnormalities in 22 symptomatic patients after cardiovascular surgery

OBJECTIVE: The aim of this study was to evaluate the types of swallowing abnormalities that occur in symptomatic patients who have undergone cardiovascular surgery. MATERIALS AND METHODS: From 1994 to 2001, 22 patients (17 males and five females; age range, 4-89 years; mean age, 64 years) who had swallowing abnormalities after cardiovascular surgery were referred for a videofluoroscopic swallowing study. Each study was analyzed for functional abnormalities of the tongue, soft palate, epiglottis, hyoid and larynx, pharynx, upper esophageal sphincter, and esophagus. Also, the performance of transesophageal echocardiography, long-term intubation, or both was noted. RESULTS: Swallowing abnormalities were present in 18 patients (81.8%) (range, one to eight functional abnormalities; mean, 3.9 functional abnormalities). The distribution of abnormalities across the functional units statistically significantly deviated (chi(2) = 14.4; df = 6; p = 0.025) from uniform distribution, with abnormalities most commonly involving the hyoid and larynx (13 patients [59.1%]) and the pharynx (10 patients [45.5%]). Aspiration was found in 13 patients (59.1%) (predeglutitive, n = 1; intradeglutitive, n = 4; postdeglutitive, n = 3; and mixed, n = 5). In the 14 patients (63.6%) who underwent transesophageal echocardiography, long-term intubation, or both, we frequently found incomplete tilting of the epiglottis, pharyngeal weakness, and postdeglutitive aspiration. CONCLUSION: Most patients with swallowing problems after cardiovascular surgery present with multiple abnormalities that most commonly affect the hyoid and larynx and the pharynx and result predominantly in intra- or postdeglutitive aspiration. The performance of transesophageal echocardiography and long-term intubation may influence the types of swallowing abnormalities.     

Barium examination of the pharynx after vertical hemilaryngectomy

Vertical hemilaryngectomy (VHL) is an effective treatment for localized true-vocal-cord carcinoma. Single- and double-contrast barium pharyngoesophagrams in 13 post-VHL patients (11 with dysphagia or suspected tumor recurrence, and two asymptomatic volunteers) were reviewed retrospectively. The two asymptomatic volunteers illustrated the normal postoperative appearance, demonstrating an unaltered pharynx, with no barium aspiration. Barium aspiration into the laryngeal vestibule or trachea was seen in 10 cases and was the only abnormal radiographic finding in four such patients. Three instances of tumor recurrence were identified. In two such cases, aspirated barium revealed a narrowed, irregular lumen of the residual laryngeal vestibule with a mass protruding into the subglottic part of the airway. The third example of recurrent malignancy was manifested by a tracheoesophageal fistula. Findings on the barium examination mimicked recurrent tumor in four cases. In one instance, a mound of granulation tissue protruding into the subglottic airway was confused with tumor recurrence. In three cases, the radiographs demonstrated apparent narrowing and mucosal irregularity of the residual laryngeal vestibule. This appearance was due to early postoperative edema or to transient deformity of the pliable residual hemilarynx during deglutition, as shown by videotaped fluoroscopy.     

Cervical osteophytes impinging on the pharynx: importance of size and concurrent disorders for development of aspiration

OBJECTIVE: This study evaluated the clinical significance of cervical osteophytes impinging on the pharynx in patients with dysphagia and the importance of concurrent disorders that may affect swallowing function. MATERIALS AND METHODS: On videofluoroscopy, anterior cervical osteophytes were found in 55 (32 men, 23 women; mean age, 69 years) of 3318 patients with dysphagia (1.7%). Coexisting diseases that affected swallowing function were found in 28 patients (stroke, n = 7; thyroidectomy, n = 7; tongue base or laryngeal cancer surgery, n = 5; other diseases, n = 9). Swallowing function was assessed with videofluoroscopy evaluating epiglottic tilting, laryngeal closure, impression of the hypopharynx, pharyngeal residue, and aspiration. RESULTS: With advancing age, the probability of aspiration (odds ratio, 1.07; p < 0.05) and of enlarging osteophytes (odds ratio, 1.26; p < 0.01) increased; the probability was higher for osteophytes at more than one vertebrae (odds ratio, 8.00; p < 0.01) and for concurrent diseases (odds ratio, 8.02; p < 0.01). Aspiration was found in 75% of patients with osteophytes larger than 10 mm and in 34% with osteophytes smaller than or equal to 10 mm. In 88% of patients with small osteophytes who aspirated, other diseases affected swallowing function. CONCLUSION: Aspiration is common in patients with dysphagia and cervical osteophytes larger than 10 mm. Aspiration is rare in patients with osteophytes smaller than or equal to 10 mm unless these patients suffer from other disorders that may affect swallowing.     

Digital cineradiographic study of swallowing in infants with neurologic disease. Our experience

PURPOSE: The study is aimed at proposing the use of digital cineradiography in the evaluation of swallowing disorders in children affected by severe neurological or developmental disability, in order to correctly identify these conditions and provide therapeutic approaches that could solve their feeding problem, improve their nutritional conditions and decrease the risk of infections. MATERIALS AND METHODS: In the period between March 2001 and July 2003, 12 children (8 males and 4 females), aged between 9 months and 13 years, (average 6.2 years), affected by severe neurological or psychomotor disorders were evaluated with digital cineradiography. This investigation was requested for recurrent pulmonary infections and/or dysphagia with weight loss. All the examinations were performed with radio-controlled equipment provided with a digital C arm. RESULTS: Using the above mentioned technique, in all 12 patients, it was possible to differentiate those with disorders of the oral and/or pharyngeal swallowing phase (9/12) from those without swallowing dysfunction (3/12). In 9/9 patients passage of contrast medium into the upper airways was observed during swallowing: in 2 of them this was limited to the laryngeal vestibule (sub-epiglottic penetration), while in 7/9 cases aspiration of contrast medium into the trachea (5/9) or into the right bronchus (1/9) or into both bronchi (1/9) was recorded. In one patient the aspiration decreased in the sequences acquired with hyperflexion of the head. In 3/9 patients we recorded the transition of contrast medium into the nasopharynx during swallowing caused by incomplete closing of the oropharyngeal isthmus by the soft palate. In 3/9 patients there was incomplete clearing of the pharynx with contrast medium deposition in glosso-epiglottic vallecules and in the pyriform sinuses; only in one case did this stagnation result in post-swallowing aspiration. More than one disorder was found in 5/9 patients, and one only in 4/9. CONCLUSIONS: On the basis of our preliminary data it is possible to conclude that the dynamic swallowing study with digital technique allows a clear-cut evaluation of the swallowing process with minimum discomfort for the patient. On the other hand, the technique exposes to the risk of ionizing radiation; however, in consideration of the important clinical and therapeutic implications and in agreement with the literature, we believe that the importance of the information provided by the technique outweighs the risks linked to radiations.     

Digital cineradiography of the pharynx and the oesophagus after total or partial laryngectomy

PURPOSE: The aim of the present study is to report our experience using digital cineradiography to assess morphological and functional disorders of the pharynx in patients with prior partial or total laryngectomy. MATERIALS AND METHODS: From March 2000 to October 2002, 21 patients (18 males and 3 females) with prior total laryngectomy (12 patients), total laryngopharyngectomy (2 patients) and partial laryngectomy (7 patients) were examined. A digital cineradiography with 12 frames/second acquisition was performed in all patients. In four patients the procedure was interrupted for massive barium aspiration, without cough (silent aspiration). In 17 patients standing in the left posterior oblique position and prone in the right posterior oblique position the oesophagus and oesophagogastric junction were also examined. The water siphon test was performed at the end of the procedure. Small boluses (10 ml) of liquid (60% w/v) and high-density (250% w/v) barium, barium paste (110% w/v), and solid meal (obtained spreading a dry biscuit with barium paste) were used. RESULTS: All patients with prior total laryngectomy and total laryngopharyngectomy showed morphological and functional disorders of the neopharynx: parapharyngeal diverticulum (2 cases), submandibular pouch (6 cases), fistulas (2 cases), lumen narrowing and post-surgical stenoses (2 cases), tumour recurrence (1 case), prominent cricopharynx (5 cases) and rhinopharyngeal reflux (4 cases). All patients with prior partial laryngectomy (7 cases) presented silent aspiration. Eleven patients had an oesophageal motility disorder, which was very serious in three of them with decrease in oesophageal clearing and barium retention in the oesophagus. Oesophagogastric junction evaluation showed hiatus hernia in six cases, two of them with associated gastro-oesophageal reflux. CONCLUSIONS: Digital cineradiography appears able to identify the organic and functional postoperative complications of patient treated with partial or total laryngectomy. A special swallowing study can suggest to the speech therapist the best compensatory mechanism for improving patient swallowing and therefore quality of life.     

Tracheobronchial foreign body aspiration in laryngectomized patient with tracheoesophageal voice prosthesis

A patient with a total laryngectomy and tracheoesophageal voice prosthesis presented with tracheobronchial aspiration of a Phillips-head screw that was swallowed inadvertently and aspirated around a loose-fitting prosthesis. A modified esophagram showed a screw in the right lung and free leakage of barium from the cervical esophagus around the prosthesis into the tracheobronchial tree. Chest radiographs and CT confirmed a screw in a right lower lobe bronchus with postobstructive pneumonia. When this complication occurs, it is important to extract the foreign body and, if necessary, to adjust or remove the prosthesis to prevent future aspiration pneumonias or foreign body aspiration.
