21/45. A parotid fistula and sialocele complicating temporomandibular joint surgery. A case of a persistent parotid fistula and sialocele following temporomandibular joint surgery is described. This rarely reported complication is postulated to result from pre-existing bucco-masseteric obstruction of parotid outflow causing raised intraductal pressure in the patient. Following unsuccessful conservative management, the patient was cured by a 5-day course of restricted oral intake and propantheline bromide. ( info) |
22/45. Parotid fistula after the use of external pin fixation: report of case. A case of parotid gland fistula after the use of external pin fixation has been described. Therapy for this condition has been discussed, with the suggestion of minimal treatment for this temporary condition. ( info) |
23/45. Absolute indications for salivary gland scintigraphy with 99mTc-pertechnetate. In recent years salivary gland scintigraphy has gained widespread acceptance as a useful means for evaluating salivary gland disorders. An absolute indication for this procedure exists when the ductal orifice of one or several major salivary glands cannot be found or cannot be cannulated. Clinical conditions in which this problem occurs include technical failure to probe and cannulate the duct, developmental anomalies, obstructive disorders, traumatic lesions and fistulae and the need of postsurgical information after glandular excision or after ligation or repositioning of a major excretory duct. The clinical value of scintigraphy in these conditions is demonstrated by means of case presentations. ( info) |
24/45. External fistula of the main parotid duct; the alternative procedure. The authors present an alternative procedure for the treatment of an external fistula of the main parotid duct. Implantation of the orifice of the duct with a flocculus of the skin into the oral cavity was performed with a good result. ( info) |
25/45. Congenital parotid gland fistula. A rare case of congenital parotid gland fistula is reported. A 4-year-old boy presented with a fistula opening at the facial surface of the skin posterior to the left commissure of the lips. This fistula originated from an accessory parotid gland with a duct entirely distinct from the original Stensen's duct. Because of the salivary outflow from the fistula opening, the opening was translocated to the oral cavity using Delore's method. ( info) |
26/45. Facial cutaneous fistula due to a foreign body in Wharton's duct. An extremely rare case of a cutaneous fistula of the submandibular salivary gland is presented. The etiology of the fistula was a foreign body in Wharton's duct. We describe the clinical course, management and histo-pathological findings. ( info) |
27/45. Congenital cervical salivary fistula. A study of 35 lesions diagnosed as branchial cleft sinuses or fistulas identified a homogeneous subgroup characterized by ectopic salivary tissue, draining serous or mucoid fluid through a short sinus tract to the base of the neck anteriorly. These lesions should more properly be called congenital cervical salivary fistulas, since they may not arise from the branchial apparatus but rather from the embryonic placodal duct. ( info) |
28/45. Wound amylase levels as an early indicator of orocutaneous fistulae. The formation of an orocutaneous fistula following ablative head and neck surgery is a common complication. Early fistula detection could permit prompt management, hopefully preventing further wound breakdowns. Amylase is quantitatively the most prominent enzyme in saliva. This study prospectively evaluated whether the amylase content of wound drainage could predict the formation of an orocutaneous fistula earlier than clinically evident. patients undergoing procedures that required postoperative wound drainage represented the study population. Baseline serum and salivary amylase determinations were obtained. The drainage was assayed for amylase content twice daily. Wound amylase values were then correlated with the patient's clinical course. Results showed wound amylase had a downward trend in uncomplicated postoperative courses. An upward trend of wound amylase was correlated with early fistulization. No pattern was identified in patients with delayed fistulae. ( info) |
29/45. A persistent parotid fistula following the extraction of mandibular teeth. A case of a persistent parotid fistula in a middle-aged patient following dental extractions is described. The management is outlined, possible conservative and surgical options are discussed, and the literature is reviewed. ( info) |
30/45. 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. ( info) |
