1/16. Salivary calculus: an insight into its pathogenesis--a case report of parotid sialolith in a 9 year old child.The occurrence of sialolithiasis in children is uncommon, while parotid sialoliths are rare. A case of parotid sialolith in a 9 year old child is reported.- - - - - - - - - - ranking = 1keywords = calculus (Clic here for more details about this article) |
2/16. Submandibular sialolithiasis: a case report.Sialolithiasis, salivary gland calculus, is a relatively uncommon condition, which may present as a painful, recurrent swelling of the affected salivary gland or duct. It can also be associated with a bacterial infection, as a result of the physical obstruction of salivary flow. This report describes the treatment of a patient with an unusually large sialolith in the submandibular duct. The patient presented with an apparent dento-alveolar abscess.- - - - - - - - - - ranking = 0.25keywords = calculus (Clic here for more details about this article) |
3/16. 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.- - - - - - - - - - ranking = 0.5keywords = calculus (Clic here for more details about this article) |
4/16. Parotid sialolithiasis in Stensen's duct.Salivary duct lithiasis is a condition characterized by the obstruction of a salivary gland or its excretory duct due to the formation of calcareous concretions or sialoliths resulting in salivary ectasia and even provoking the subsequent dilation of the salivary gland. Sialolithiasis accounts for 30% of salivary diseases and most commonly involves the submaxillary gland (83 to 94%) and less frequently the parotid (4 to 10%) and sublingual glands (1 to 7%). The present study reports the case of a 45-year-old male patient complaining of bad breath and foul-tasting mouth at meal times and presenting with a salivary calculus in left Stensen's duct. Once the patient was diagnosed, the sialolith was surgically removed using local anesthesia. In this paper we have also updated a series of concepts related to the etiology, diagnosis and treatment of sialolithiasis.- - - - - - - - - - ranking = 2.2163301127914keywords = salivary calculus, calculus (Clic here for more details about this article) |

6/16. Giant salivary calculi: an orocervical fistula caused by a submandibular gland calculus.Large calculi of the salivary glands are rare. They may go undetected for many years. The authors report three cases of giant submandibular gland calculi. In one patient, the calculus was an incidental finding. In all patients, the mass was in the substance of the gland; in one, the configuration of the mass was unusual and it had eroded through the floor of the buccal cavity forming an orocervical fistula (the first such report) and in another the mass occupied a small portion of Wharton's duct. The histopathologic findings in all three cases were of nonspecific chronic inflammation. All the patients made a smooth recovery and had no complaints at follow-up.- - - - - - - - - - ranking = 1.25keywords = calculus (Clic here for more details about this article) |
7/16. Recurrent calculus formation following removal of the submandibular salivary gland.Three cases are presented in which calculi appear to have reformed in the submandibular duct many years after the total removal of the submandibular gland. The basis for this is presumed to be the existence of communications between the sublingual glandular complex and the remaining submandibular duct.- - - - - - - - - - ranking = 1keywords = calculus (Clic here for more details about this article) |
8/16. Sialolithiasis of a Blandin's gland duct.A case of sialolithiasis in a Blandin's gland duct is reported. Although minor salivary glands calculi are not uncommon, Blandin's glands are rare sites of occurrence. In this case, a calculus without decalcification is reported. Not only clinico-pathological features but also electron probe micro analyzer plus energy dispersive X-ray spectroscopy studies are presented. These studies reveal that phosphorus is contained in only the basophilic part of the calculus and sulphur in both the basophilic and the eosinophilic parts.- - - - - - - - - - ranking = 0.5keywords = calculus (Clic here for more details about this article) |

10/16. The gigantiform salivary calculus.The size of salivary calculi may range from small particles to large concrements of several centimetres. One case of a gigantiform salivary calculus located in the Wharton duct of a 48-year-old man is presented. After surgical removal of the 3.6 cm long concrement, it was split into 4 parts. The different parts were used for routine histological studies, production of microradiographs of ground sections and for scanning electron microscopy. Decalcified sections disclosed a specimen made of a homogeneous central nucleus and a peripheral lamellation. The same morphological picture was seen on the microradiographs, where the nucleus showed dense mineralization, and the peripheral part alternating rings of high and low mineral content. Microorganisms, mostly thread-like organisms, were found throughout the entire calculus in specially stained sections. Scanning electron microscopy confirmed the histologic and microradiographic findings. The presence of microorganisms also in the nucleus of the calculus seems to be one important aetiological factor favouring the formation of this gigantiform concrement.- - - - - - - - - - ranking = 11.581650563957keywords = salivary calculus, calculus (Clic here for more details about this article) |
