The Stafne defect is thought to be a normal anatomical variant, as the depression is created by ectopic salivary gland tissue associated with the submandibular gland and does not represent a pathologic lesion as such. This cavity is commonly observed on panoramic radiograph.
However, salivary tumors show a great deal of morphological diversity, as well as variations in the nature of the lesion (malignant vs. benign): approximately 20% to 25% of parotid tumors, 35% to 40% of submandibular tumors, and more than 90% of sublingual gland tumors are malignant. [8]
Benign tumour of the submandibular gland, also known as pleomorphic adenoma, presented as a painless neck mass in a 40-year-old man. At the left of the image is the white tumour with its characteristic cartilaginous cut surface. To the right is the normally lobated submandibular salivary gland. Warthin's tumor; Myoepithelioma; Basal cell ...
Swelling in the submandibular area in a person with Ludwig's angina. Specialty: Otorhinolaryngology, oral and maxillofacial surgery Symptoms: Fever, pain, a raised tongue, trouble swallowing, neck swelling [1] Complications: Airway compromise [1] Usual onset: Rapid [1] Risk factors: Dental infection [1] Diagnostic method: Based on symptoms and ...
About 85% of stones occur in the submandibular gland, [3] and 5–10% occur in the parotid gland. [2] In about 0–5% of cases, the sublingual gland or a minor salivary gland is affected. [ 2 ] When minor glands are rarely involved, caliculi are more likely in the minor glands of the buccal mucosa and the maxillary labial mucosa. [ 4 ]
Adenoid cystic carcinoma is a rare type of cancer that can exist in many different body sites. This tumor most often occurs in the salivary glands, but it can also be found in many anatomic sites, including the breast, [1] [2] lacrimal gland, lung, brain, Bartholin gland, trachea, and the paranasal sinuses.
A study done on the epidemiology of sialadenitis in the United States of America found that acute suppurative parotitis is responsible for 0.01–0.02% of hospital admissions, with the submandibular gland accounting for 10% of cases of sialadenitis in the major salivary glands in this population. [1]
Based on a meta-analysis, the prevalence of pSS worldwide is estimated to 0.06%, with 90% of the patients being female. [26] In secondary Sjögren syndrome (sSS), individuals have a dry mouth, dry eyes and a connective tissue disorder such as rheumatoid arthritis (prevalence 7% in the UK), systemic lupus erythematosus (prevalence 6.5%–19% ...
