1/11. Salivary duct cyst: its frequency in a certain Japanese population group (Tohoku districts), with special reference to adenomatous proliferation of the epithelial lining.It is reported in the European and American literature that salivary duct cysts constitute about 10% of all cysts of the salivary glands, although they appear to be rare in japan. Between 1975 and 1999, only 3 (0.5%) of 586 salivary gland cysts were diagnosed as salivary duct cysts at the Division of Clinical pathology, Iwate Medical University Hospital. Histologically, two cases appeared as a unilocular lesion lined by double- and multi-layered epithelium. The other case showed marked, intraluminar and intramural adenomatous proliferation of the epithelial lining, suggesting that the lesion was a benign tumor. A review of the literature yielded only two cases of tumors arising in pre-existing salivary duct cysts.- - - - - - - - - - ranking = 1keywords = salivary duct, duct (Clic here for more details about this article) |
2/11. Plunging ranula as a complication of intraoral removal of a submandibular sialolith.Mucous cysts in the submandibular region--so-called 'plunging' ranula--are relatively uncommon. We report a case of a plunging ranula that complicated excision of an intraductal sialolith of the submandibular gland.- - - - - - - - - - ranking = 0.0009040081367069keywords = duct, ductal (Clic here for more details about this article) |
3/11. Management of pediatric ranula.OBJECTIVE: Many surgical techniques to manage ranulas have been described in the literature. These techniques include excision of the cyst with or without excision of the ipsilateral sublingual gland, marsupialization, cryosurgery, and CO(2) laser excision. Few studies have described the approach toward management in pediatric patients. methods: Six patients were treated for intraoral ranulas. Two patients had spontaneous resolution of their lesions. Four patients required dissection of the submandibular duct and lingual nerve to completely excise an oral cavity ranula and an ipsilateral sublingual gland. RESULTS: There were no recurrent lesions. One patient developed a lingual nerve injury but no numbness. The 2 patients with spontaneous resolution did not develop a subsequent lesion. CONCLUSION: Optimal management of pediatric oral cavity ranulas may include observation for 5 months for spontaneous resolution. If the lesion does not resolve or recurs repeatedly, surgical treatment is recommended. Submandibular duct dissection with relocation appears to enhance exposure to the floor of mouth. The pseudocyst and entire sublingual gland should be removed. Identification of the lingual nerve is necessary to accomplish this goal.- - - - - - - - - - ranking = 0.00109766517487keywords = duct (Clic here for more details about this article) |
4/11. Congenital ranula. A report of two cases.We report 2 unusual cases of congenital ranula in male Nigerian infants. Clinical examination could not discern the orifice of the submandibular duct on the affected sides, while a lower occlusal radiograph revealed no obvious calculi. diagnosis was mainly by clinical presentation. The paper highlights possible aetiopathogenesis, clinical aspects and diagnostic features. Emphasis is laid on the need for careful evaluation of oral ranulas in order to discern their origin and provide appropriate treatment.- - - - - - - - - - ranking = 0.00054883258743498keywords = duct (Clic here for more details about this article) |
5/11. Pediatric intraoral ranulas: an analysis of nine cases.An intraoral ranula is a retention cyst arises from the sublingual gland on the floor of the mouth as a result of ductal obstruction and fluid retention. Many techniques for management of ranulas have been described in the literature. The purpose of this study was to analyze our surgically treated pediatric patients with intraoral ranulas and to discuss the results in the light of the literature. Nine pediatric patients (six females and three males) with intraoral ranulas surgically treated were analyzed retrospectively regarding their treatment methods and results. The surgical specimens were also re-examined histologically. Seven cases of superficial, protruded and smaller than 2 cm ranulas were treated with marsupialization (unroofing). Two cases who were previously operated and then recurred had bigger than 2 cm ranulas. In these two cases, marsupialization of the ranula plus removal of the sublingual gland was performed. The most common complication was intraoperative cyst rupture of the ranula, which was noted in four cases. A recurrence was observed in only one case in the 16th months of follow up period. Our findings show that marsupialization is a suitable and effective method for pediatric intraoral ranulas, whereas in recurrent cases marsupialization of the ranula combined with total excision of sublingual gland may be preferred.- - - - - - - - - - ranking = 0.0009040081367069keywords = duct, ductal (Clic here for more details about this article) |
6/11. Treatment of a ranula using an Er,Cr:YSGG laser.A ranula is an extravasational cyst arising from the sublingual gland. The "cyst" cavity does not have an epithelial lining, and because of this is notoriously difficult to eliminate. Usual treatment requires complete excision of the sublingual gland, exteriorizing the gland through establishment of a secondary ductal structure by placement of a long-term indwelling catheter, or packing, all requiring patient compliance. Unroofing alone is often followed by recurrence via resealing or closure with formation of a new roof. The accompanying scarring and damage to additional ducts may also result in recurrence. Combining unroofing with a technique that would prevent resealing of the remaining portion, scarify the base of the ranula to eliminate residual glandular acini, and be more comfortable and non-interfering with the daily activity of the patient, is an acceptable object of treatment of a ranula. The use of a water-based laser system to accomplish these goals appears to be a desirable and simple method.- - - - - - - - - - ranking = 0.0014528407241419keywords = duct, ductal (Clic here for more details about this article) |
7/11. Plunging ranula following bilateral submandibular duct transposition.Submandibular duct transposition is now a standard surgical procedure for the treatment of severe drooling. However, this is our first experience of a plunging ranula arising as a complication of the technique. In the surgical management of this complication, the single most important step is excision of the sublingual gland to prevent recurrence.- - - - - - - - - - ranking = 0.0027441629371749keywords = duct (Clic here for more details about this article) |
8/11. Plunging ranula: a report of three cases and review of the literature.Three cases of plunging ranula are reported and the literature reviewed. Extravasation of saliva from the sublingual gland due to trauma or obstruction of its ducts appears to be the most likely cause of plunging ranula. Available data suggest that the submandibular gland is usually not involved, although at the time of surgery it may be extremely difficult to exclude a submandibular origin of the cyst in the neck. communication between the oral and cervical components of the plunging ranula probably occur via a hiatus in the mylohyoid muscle. Such communication passing directly into the submandibular compartment may simulate submandibular gland involvement. Since 1910, 139 procedures in 89 patients with plunging ranula have been reported in the English literature. The recurrence rate was 70 per cent after incision and drainage of the cyst, 53 per cent after marsupialization, 85 per cent after excision of the cyst in the neck and 2 per cent after excision of the sublingual gland via the cervical or intra-oral route. This review suggests that excision of the sublingual gland with intra-oral drainage of the cervical swelling appears to be the treatment of choice for the plunging ranula.- - - - - - - - - - ranking = 0.00054883258743498keywords = duct (Clic here for more details about this article) |
9/11. sublingual gland salivary fistula and sialocele.A case of cutaneous salivary fistula and sialocele in the submental area, arising from the sublingual gland, is reported and its etiology, development, and management are discussed. The entity of plunging ranula is compared to the lesion the case presented, and the literature regarding this lesion is reviewed. The successful surgical treatment of this case supports the theory that the sublingual gland is the source of the disorder. The effect of the altered salivary function on the adjacent submandibular gland and duct presented an operative complication.- - - - - - - - - - ranking = 0.00054883258743498keywords = duct (Clic here for more details about this article) |
10/11. Cystic lymphangioma and plunging ranula treated by OK-432 therapy: a report of two cases.Among head and neck angiotumors, cystic lymphangioma occurs in infancy in most cases and it is rare in adulthood. Plunging ranula is one of the diseases which need to be distinguished from lymphangioma, though operation is the first choice therapy for both of these. In the present study, we report on 2 cases in whom we conducted intralesional injection of OK-432 for cervical lymphangioma and ranula found in 20 and 35 year-old female patients. We obtained excellent improvement. First of all, we punctured the tumors and sucked out the liquid content as much as possible, and then used OK-432 in the same volumes to those drawn out. No swelling was observed in either patient after 1 month, and cysts disappeared in CT 4 and 12 months after injection, respectively; at present, the prognosis is satisfactory, without recurrence. The intralesional injection of OK-432 is considered an effective method, as the speed of complete disappearance by this therapy is high. Cosmetically it is superb, leaving no lesions in the skin of the injection site.- - - - - - - - - - ranking = 0.00054883258743498keywords = duct (Clic here for more details about this article) |
