A rare case of second branchial fistula with heterotopic salivary gland tissue in the lower neck is described. The patient was a 12-year-old girl with a fistula which appeared to be clinically a second branchial cleft anomaly. It was removed from her neck. Histological examination revealed that the lesion was a branchial cleft fistula with elements of salivary gland tissue.
Expanding Silastic foam was used to close and dress a large orocutaneous salivary fistula secondary to a massive local recurrence of squamous cell carcinoma. The technique is simple, rapid, and effective. The patient found the dressing superior in every way to the traditional absorbent dressings previously supplied. We recommend this technique for the closure of large defects in the head and neck.

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.
Sialography is of value for showing opaque or nonopaque stones in the maxillary glands. Possible complications (inflammation, abscess and fistula) can also be shown. Acute and chronic inflammation and sialadenoses show typical pictures. The diagnosis of tumors is less certain, genignity or malignity cannot be determined.
Heterotopic islands of salivary-gland tissue are rare and have been described in a number of sites in the head and neck. We describe a patient with salivary-gland fistulas in the lower third of the neck, without evidence of any other congenital abnormalities. The appearance of sinuses in association with heterotopic salivary-gland tissue suggests that its embryologic origin may be from the branchial clefts. Surgical treatment is recommended.
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.
The vast field encompassed by the non-tumorous diseases of the salivary glands poses difficult problems for their diagnosis and therapy. In order to facilitate comprehension of the pathological processes and the therapeutical possibilities for their treatment, physiological and biochemical aspects of salivary gland function are presented in the introduction. There are also mentioned in detail most of the diagnostic methods clinically applied today and stress is laid on their respective diagnostic values. In contrast to the opinion of many authors, exploratory excision and puncture are shown to be very important diagnostic tools in salivary gland pathology. The specific application of these methods is often the only means for a reliable diagnosis. The classification of the diseases follows Seifert's (1971) proposal. The chronic diseases of the salivary glands are specifically mentioned with the chronic recurrent and the chronic myoepithelial sialoadenitis taking first place. The sialoses are presented in a larger chapter. An attempt was made to correlate clinical and experimental results, to establish working hypotheses concerning the development of sialoses, to suggest therapeutical possibilities and, last not least, to give an idea of the many clinical and patho-anatomical difficulties to be overcome for a satisfactory understanding of such pathological processes. Finally, various forms of salivary gland fistulas and their treatment are mentioned. The long list of references merely gives an approximation of the abundance of publications dealing with the problems of this field.
The majority of extraoral facial fistulas are of odontogenic origin. Although the differential diagnosis of draining lesions should include various types of skin infection, infected tumour, specific infections, failed wound healing, foreign body, salivary gland fistula, sebaceous cysts and developmental cysts and fistulas. This report documents a group of patients with extraoral draining skin lesions and illustrates that their diagnosis is very important because clinically they can resemble many pathologic entities. One hundred and twenty-eight cases of extraoral fistulas are presented in this paper. This study aims to analyse a number of fistula cases so as to give a clear idea about relative frequency of etiology and to attract to some cases of non odontogenic etiology.

Observations were made in sheep, before and after fresh food was given during teasing with food and after rumination, on the flow of parotid saliva and its protein Mg2+, K+, Na+ and Cl- concentrations. The animals studied had either a cannulated or fistulated parotid salivary duct. Parotid salivary flow, protein, Mg2+, K+ and Cl- increased markedly following feeding. The increases in protein and Mg2+, but not in flow, were largely blocked by the i.v. administration of propranolol (1 mg . kg-1). Whereas the actual ingestion of food was associated with large increases in protein (up to 42.5 times, to as high as 1760 micrograms . ml-1 of saliva), teasing with food caused relatively minor increases in parotid saliva. There were slight, if any, changes in protein concentration during the increased parotid salivary flows of rumination, whether chewing was on the same side or contralateral to the cannulated parotid salivary duct. It is concluded that a beta-adrenergic mechanism previously demonstrated in acute experiments contributes to increases in the secretion of protein of the parotid saliva when sheep eat. There was a close correlation between the concentrations of protein and of Mg2+ but not of the other electrolytes studied.
The purpose of this study was to review retrospectively the outcomes for 157 patients treated for maxillofacial fractures between 1994 and 1999 at one military hospital in Turkey. Significant data were collected according to age, gender, time of injury, type of facial injuries, cause of injury, treatment methods, and postinjury and postoperative complications. Fractures resulting from gunshot wounds were excluded in this study. Fractures were examined in two groups according to the type of fracture, i.e., isolated or combined. Methods of fixation with closed or open reduction were used to treat the fractures. Fixation was performed with miniplates, compression plates, microplates, reconstruction plates, and wires for open reduction, and stabilization was performed with arch bars for closed reduction. Complications were recorded in two groups, i.e., postinjury and postoperative complications. There were 151 male patients (96.18%) and 6 female patients (3.82%). The patients ranged in age from 15 to 62 years (mean, 22.8 years). In our study, it was determined that the most significant causes of maxillofacial fractures were traffic accidents (69 cases, 43.95%) and fighting (42 cases, 26.75%). Most fractures were in the mandible (161 fractures). It was observed that most of the mandibular fractures were in the body (49 fractures, 30.43%) and condylar (42 fractures, 26.09%) regions. Of the 223 maxillofacial fractures, 63.68% (142 fractures) were treated with closed reduction and 36.32% (81 fractures) were treated with open reduction. Postinjury complications included infections (local infection or osteomyelitis), nerve injuries (alveolaris inferior, facial, lingual, and infraorbital nerves), and a salivary gland fistula, and postoperative complications included infection, facial asymmetry, and malocclusion.

A patient is described, treated at the clinic for a disease, being a casuistic rarity. A child of 6 is concerned with a congenital skin fistula in the region of the neck, arising from the sublingual salivary gland. The treatment covers the radical extirpation of the gland with excision of the fistula duct. After an uneventful postoperative period, complete healing was attained.
