Sialolithiasis is one of the most common pathologies of the submandibular gland; sialoliths account for about 80 percent of all salivary duct calculi.The majority of sialolith occurs in the submandibular gland or its duct and is common cause of acute and chronic infection. Salivary stones larger than 15 mm are classified as giant sialoliths. They are uncommon in the practice of otolaryngology, ...

BACKGROUND AND PURPOSE Although radiation induced damage to the salivary gland is a known complication of radioactive iodine ((131)I) therapy for thyroid carcinoma, prediction of the severity and reversibility of sialoadenitis is difficult. Our aim was to correlate the extent of salivary dysfunction assessed by salivary gland scintigraphy with changes in the volume and attenuation of salivary g...

Long-term submandibular duct obstruction is thought to cause irreversible atrophy and dysfunction of the submandibular gland. As an atrophic gland may be induced clinically by chronic or recurrent infection, it is generally removed surgically. However, the regenerative capacity of atrophic submandibular glands after long-term obstruction is not completely understood. We studied the regenerative...

A 45-year-old female was referred to the Department of Oral and Maxillofacial Surgery with the complaint of pain in the right submandibular region and a dry mouth, which had started one week previously. A clinical examination revealed a swelling and tenderness in the right submandibular region. Panoramic radiography and computed tomography identified a sialolith in the submandibular gland. Surg...

OBJECTIVES brain-derived neurotrophic factor (BDNF), which is produced in rat submandibular gland, is one of the most abundant neurotrophins in the central nervous system. It is generally accepted that occlusal disharmony causes stress. The purpose of the present study was to investigate whether occlusal disharmony-induced chronic stress affects BDNF levels and morphology in rat submandibular g...

Transient receptor potential vanilloid subtype 4 (TRPV4) is a ligand-gated nonselective cation channel that participates in the transduction of mechanical and osmotic stimuli in different tissues. TRPV4 is activated by endogenous arachidonic acid metabolites, 4α-phorbol-12,13 didecanoate, GSK1016790A, moderate heat, and mechanical stress. TRPV4 is expressed in the salivary glands, but its expre...

Hyposecretion occurs in most patients early after submandibular gland autotransplantation for severe keratoconjunctivitis sicca. Endogenous transient receptor potential vanilloid subtype 1 (TRPV1) has been recently demonstrated in rabbit submandibular glands, and activation of TRPV1 by capsaicin increases secretion in isolated glands, but the TRPV1-mediated secretory mechanism remains to be elu...

OBJECTIVE This study presents a clinicopathologic review of cases of submandibular salivary gland tumours at the Lagos University Teaching Hospital, Nigeria, over a period of 17 years. METHODS The records of all patients with histological diagnosis of submandibular salivary gland tumours at the Lagos University Teaching Hospital over a period of 17 years (January 1990 to December 2006) were r...
