Ultrasound analysis of the upper esophageal sphincter during swallowing in the healthy subject.

OBJECTIVES: The purpose of this study was to develop a methodology and standard settings for ultrasound study of the upper esophageal sphincter (UES) during swallowing. MATERIAL AND METHODS: This was a prospective study of 25 healthy volunteers (15 women and 10 men) aged 20 to 56 years. Neck ultrasonography was performed as each volunteer swallowed 10 mL of water three times. The parameters studied were: diameter of the closed UES; diameter of the open UES; anterior and lateral displacement (measured in cm) of the UES as the water bolus flowed through it; duration of UES opening; and average duration of UES displacement (measured in ms). Student's t tests for paired and unpaired samples were applied for the statistical analysis. RESULTS: The mean diameter of the closed UES was 0.78 ± 0.13 cm, while the mean duration of opening was 415 ± 57.66 ms and the mean duration of displacement was 937 ± 120.98 ms. Maximum anterior and lateral displacement of the UES was 0.42 ± 0.12 cm and 0.35 ± 0.18 cm, respectively. There was a significant difference between men and women for lateral displacement of the UES (P=0.04). CONCLUSION: This study established standards for ultrasound study of the UES during swallowing, using a non-invasive readily accessible method that may be useful for assessing swallowing disorders involving the UES (Zenker's diverticulum, fibrosis, stricture).

[Post intubation collected septic cricoarytenoid arthritis: case report]. / Arthrite infectieuse collectée de l'articulation crico-aryténoïdienne secondaire a une intubation: cas clinique.

We report a rare case of post intubation cricoarytenoid arthritis. A 18-year-old man admitted to emergency was easely intubated for 14 days for a non neck injury. Sixty-six days after intubation, he consulted for severe odynophagia with dyspnoea. Nasofibroscopic examination revealed a right arytenoid granuloma with oedema and inflammation, and bilateral arytenoid immobility. There was evidence on the CT scan of cricoarytenoid arthritis with fluid accumulation. Antibiotic treatment and two punctures for drainage allowed healing. There were cricoid and arytenoid calcifications. The patient recovered total and stable laryngeal mobility and function. This case is unusual, with features unlike those previously reported: intubation being the probable cause, the unusual clinical presentation with painless cricoid palpation, and the contrast between imaging findings during follow-up and the evolution under treatment. Indeed, there was an apparent discrepancy between the favourable clinical course and the CT-images revealing calcifications.

[Persistent dysphonia showing a laryngeal foreign body in a child]. / Dysphonie persistante révélant un corps étranger laryngé

INTRODUCTION: Inhalation of a laryngotracheobronchial foreign body is a common pediatric emergency situation. It is a source of morbidity and even mortality, especially among children under 3 years of age. CASE REPORT: A 14-month-old child presented suddenly combining bitonal dysphonia and dyspnea. Given the persistence of symptoms after 1.5 months and the normality of examinations requested by his doctor (pH, cervical ultrasonography, cervical and thoracic radiography), an ENT opinion was sought. An aerodigestive tract endoscopy was carried out in the emergency setting, finding a glottic foreign body associated with subglottic granulomas. The foreign body extraction led to the immediate disappearance of dyspnea. Dysphonia gradually improved under Budesonide aerosols. CONCLUSION: The lack of penetration syndrome in the interrogation and non specific symptoms may lead to an important diagnosis and treatment delay with dramatic consequences in case of airway foreign body. Endoscopy under general anesthesia must be practiced if there is any doubt for a thorough examination of the airways.

[Childhood septic temporomandibular arthritis]. / Arthrite septique temporomandibulaire de l'enfant.

OBJECTIVE: To report a clinical case of acute otitis media in a child, complicated by septic temporomandibular arthritis and to present a review of the literature. PATIENT AND METHODS: We report a case of a 7-year-old boy who presented an altered general condition, major hyperthermia, associated with a left temporozygomatic mass in a context of recurrent bilateral acute otitis media lasting for 2 months. Emergency computed tomodensitometry (CT scan) showed left temporomandibular joint arthritis. Treatment consisted of a parenteral double antibiotic therapy and prevention of temporomandibula (TM) ankylosis. RESULTS: After 20 months of follow-up, the child showed a normal ORL examination with no maxillofacial sequelae. CONCLUSION: All temporozygomatic masses presenting in a septic context should suggest the diagnosis of TM arthritis; computed tomodensitometry should be done immediately.
