Background and Objectives Sialendoscopy is useful for the diagnosis treatment of obstructive salivary gland diseases, but not yet universally employed because it requires dedicate, expensive, fragile endoscopic equipment; moreover, surgical technique also delicate. Here, we describe our initial experience sialendoscopy, as well learning curve, precautions, drawbacks that beginners must overcome...

BACKGROUND Leiomyosarcoma is a rare malignant mesenchymal tumor that represents 5-7 % of all soft tissue sarcomas. The occurrence of this tumor in the salivary glands is exceptional. Only five cases are reported in the submandibular gland. CASE PRESENTATION A 65-year-old white Moroccan woman presented with a history of progressive right submandibular swelling which had grown over a period of ...

PURPOSE We aimed to assess the problem solving capability of magnetic resonance sialography (MR sialography), a noninvasive method for imaging submandibular gland ducts and determining duct-related pathologies, by comparing diseased and healthy cases. MATERIALS AND METHODS We conducted radiological assessment on a total of 60 submandibular glands (mean age 44.7) in 20 cases and 10 volunteers....

To clarify the mechanisms underlying the submandibular gland atrophies associated with ptyalolithiasis, morphological changes were examined in the rat submandibular gland following either surgical intervention of the duct or functional blockade at substance P receptors (SPRs). Progressive acinar atrophy was observed after duct ligation or avulsion of periductal tissues. This suggested that dama...

Ectopic thyroid tissue is seen rarely. It is often seen in cervical midline, and rarely in other areas such as submandibular area. Diagnosis is made histopathologically by fine needle biopsy after the elimination of malignancy. In the treatment of ectopic thyroid tissue, surgical excision is mostly applied. According to our knowledge, there is no exophytic thyroid tissue reported in the literat...

PURPOSE Cadmium toxicity in the exposure of the general, professional and cigarette smoking populations has been well known. From the dental point of view, it is important to find out whether and how separate and joint exposures to cadmium and zinc affect the structure and function of the submandibular gland, which is the major saliva-releasing gland. Cadmium, a particularly active xenobiotic, ...

We examined morphological differences between the sublingual and submandibular glands with special reference to their innervation. The sublingual gland contained abundant periodic acid Schiff-positive mucous acini: some lobules were composed of purely mucous acini, while others were purely serous or mixed. However, in the submandibular gland, the area of mucous acini was very limited. Notably, ...

OBJECTIVE To compare the accuracy of ultrasound (US)-guided and non-US-guided botulinum toxin (BTX) injection into the salivary glands (parotid and submandibular glands) of cadavers. METHODS Two rehabilitation physician injected dye into three sites in the salivary glands (two sites in the parotid gland and one site in the submandibular gland) on one side of each cadaver (one was injected on ...

This study was carried out to evaluate the effect of administration of aspartame in two doses (40mg/kg and 80mg/kg body weight) on the submandibular salivary glands of male albino rats. Ninety adult male rats weighing (200-250g) were used in this study. Animals in each group were caged in separate cages in the animal house at the Faculty of Dentistry, Minia University. Pure aspartame (APM) powd...

Ectopic thyroid gland is a rare phenomenon that appears most frequently in the cervical midline and very rarely in other sites such as the submandibular region. This article reports a painless, non-tender and firm thyroid tissue mass in the right submandibular region of a 29-year-old female patient. Physicians should consider ectopic thyroid tissue as a differential diagnosis of submandibular s...
