1/57. Pneumoparotid due to spirometry.

    Pneumoparotid has been described in patients who generate increased intraoral pressures when playing wind instruments, while coughing, and when undergoing dental work. Some patients have intentionally created pneumoparotid to avoid duties at school or in the military, or to gain attention. We describe a patient who developed pneumoparotid during pulmonary function testing. The diagnosis of pneumoparotid depends on a suggestive clinical situation and glandular swelling with or without crepitus. observation of aerated saliva per Stensen's duct or air in the parotid duct and/or gland by any imaging study is diagnostic if infection with a gas-forming organism can be reasonably excluded. No specific treatment is required, other than the avoidance of predisposing activities.

2/57. The role of computerized tomography in the diagnosis and therapy of parotid stones: a case report.

    BACKGROUND: Small, semi-calcified parotid stones are difficult to diagnose as imaging can be extremely difficult. Understanding how to diagnose parotid stones is important to dentists, however, because people with this condition develop parotid swellings and may seek routine dental care. CASE DESCRIPTION: The authors describe a classic case of parotid sialadenitis secondary to a small lucent stone in Stensen's duct. They discovered the stone only because of the keen sensitivity of computerized tomography, or CT, to minimal amounts of calcific salts. The CT scan's ability to accurately locate the stone and its position within 1 centimeter of the orifice facilitated a successful intraoral surgical approach. CLINICAL IMPLICATIONS: CT can be a significant aid in early diagnosis and therapy of patients with parotid stones, who eventually develop sialadenitis. With early intervention, further gland degeneration and parotidectomy will be prevented.

3/57. MR sialographic evaluation of sialectasia of Stensen's duct: comparison with X-ray sialography and ultrasonography.

    We describe a patient with unilateral sialectasia of Stensen's duct. X-ray sialography, MR sialography, and ultrasonography showed multiple stenoses and rosary dilatation of Stensen's duct during stimulation of the parotid gland. Before stimulation, Stensen's duct showed focal dilatation as indicated by MR sialography and ultrasonography. The patient also had ipsilateral masseter hypertrophy (BMH), which may be a cause of sialectasia.

4/57. rhinosporidiosis of the parotid duct cyst: cytomorphological diagnosis of an unusual extranasal presentation.

    This cytology report highlights a case of rhinosporidiosis of the parotid duct cyst not associated with nasal manifestations. In an endemic area, one should be familiar with its morphologic features in fine-needle aspiration cytology even on scanty material, for it could be one of the investigations in the initial workup of a case.

5/57. shock wave lithotripsy of a parotid duct calculus.

    Extracorporeal shock wave lithotripsy, a relatively new non-invasive method of treating salivary gland calculi, is rarely used in UK hospitals. We present a case of parotid duct calculus treated successfully by lithotripsy in a United Kingdom (UK) district General Hospital.

6/57. Treatment of parotid ductal stenosis and concomitant resolution of autonomic symptomatology.

    Salivary retention and recurrent sialadenitis as a result of ductal stenosis is an uncommon condition that presents difficult management problems. Ductal dilation with small angioplasty balloons is recognized to be of low morbidity and can eliminate the possible need for surgical intervention. This case report is interesting in that the successful treatment of parotid duct stenosis was accompanied by the resolution of a spectrum of autonomic symptoms that had seriously compromised the patient's quality of life.

7/57. Combined approach to impacted parotid stones.

    PURPOSE: This article describes the use of combined endoscopic and ultrasound approach to locate and to extract impacted parotid stones, which cannot be retrieved by intraoral approach alone. patients AND methods: A total of 12 parotid glands from 7 women and 5 men (age range, 35 to 62 years) with parotid sialoliths were treated with the combined method. Eleven of 12 of the procedures were performed under local anesthesia in an outpatient clinic. The identification of the calculi was done in 5 patients with 1.3-mm sialoendoscope (Nahlieli Sialoendoscope; Karl Storz, Tuttlingen, germany) in 6 patients with the aid of high-resolution ultrasound, and in 1 patient the location was combined endoscopy and ultrasound. The removal of the calculi was performed extraorally via minimal incision. The indications for the combined approach were 1) calculus in the posterior third of the Stensen's duct with too narrow duct anterior to it, 2) obstruction of the posterior or middle third of the Stensen's ducts leading to the calculus, 3) large (>5-mm) stones in the middle or posterior part of the duct that cannot be dilated for intraductal removal, and 4) intraparenchymal stones. RESULTS: Of the 12 patients, 9 had complete removal (75%); in 1 case with 3 sialoliths, we removed 2 and the gland remained asymptomatic. In 7 cases, the glands returned to function, 3 glands became atrophic with no function, but the gland remained asymptomatic. The aesthetic results were satisfactory in all cases, no major complications were noted. CONCLUSIONS: Combined endoscopic ultrasound approach is another minimal invasive technique for identification and removal of impacted parotid sialolithiasis.

8/57. hiv parotid gland lymphoepithelial cysts. review and case reports.

    Lymphoepithelial cysts of the parotid gland are frequently associated with cervical lymphadenopathy. These unique cysts have recently been recognized as another manifestation of hiv disease. Proliferation of lymphocytes and salivary gland tissue contained within intra-parotid lymph nodes is observed. The lymphoepithelial cyst is the end product. Ultrasound imaging serves as an excellent technique to demonstrate the existence of these cysts.

9/57. Bilateral parotid voluminous masses: a case report.

    The case of a 75-year-old woman with voluminous bilateral symmetrical masses of the parotid glands is reported, and the literature relevant to the differential diagnosis in bilateral neoplastic and nonneoplastic parotid masses is reviewed. The presurgical workup was based on clinical evaluations, nuclear magnetic resonance imaging findings, and cytologic examination to obtain the differential diagnosis. Benign or malignant tumors were excluded. Surgery was performed for esthetic reasons and in consideration of progressive enlargement of lesions. Histopathologic examination of resected masses revealed benign lymphoepithelial cysts with polyclonal infiltration of lymphoid cells. Serological testing for tuberculosis, cytomegalovirus, human immunodeficiency virus, and Epstein-Barr virus (EBV) and testing using the in situ hybridization technique for the presence of cytomegalovirus and EBV were negative for productive infection or viral replication. A diagnosis of retention cysts was suspected on the basis of presurgical evaluation, histopathological examination, and serologic analysis. In this case, bilateral obstruction of the parotid ducts by a mobile denture probably played the main role in the pathogenesis and development of bilateral parotid retention cysts, because any other specific cause for the pathogenesis was not found with diagnostic tools.

10/57. Diagnosing bulimia nervosa with parotid gland swelling.

    BACKGROUND: The authors describe bulimia nervosa, or BN, and its effect on the parotid gland. The associated asymptomatic bilaterally enlarged parotid glands often present a diagnostic dilemma. CASE DESCRIPTION: The authors present a case of a 22-year-old woman with BN who had bilateral parotid gland swelling, serum electrolyte alteration and no dental stigmata. Her principal concern was the associated cosmetic deformity. CLINICAL IMPLICATIONS: Because patients with BN who have parotid gland swelling usually are secretive about their purging, the diagnosis may be confirmed by conducting a clinical examination and a serum electrolyte study. Prompt diagnosis can avoid serious medical complications.
