Pneumoparotitis (also termed pneumosialadenitis [1] wind parotitis, [1] surgical mumps, [2] or anaesthesia mumps), [2] is a rare cause of parotid gland swelling which occurs when air is forced through the parotid (Stensen) duct resulting in inflation of the duct.
Acute bacterial parotitis: is most often caused by a bacterial infection of Staphylococcus aureus but may be caused by any commensal bacteria. [2] Parotitis presents as swelling at the angle of the jaw. Bacterial parotitis presents as a unilateral swelling, where the gland is swollen and tender and usually produces pus at the Stensen's duct.
Treatment may include the following: Surgery Complete surgical resection, with adequate free margins, is currently the mainstay treatment for salivary gland tumours. However elective treatment of the N0 neck region remains a controversial topic; Radiotherapy [4] If a salivary gland tumour is cancerous, Radiation Therapy may be necessary
The parapharyngeal space (also termed the lateral pharyngeal space), is a potential space in the head and the neck. It has clinical importance in otolaryngology due to parapharyngeal space tumours and parapharyngeal abscess developing in this area. It is also a key anatomic landmark for localizing disease processes in the surrounding spaces of ...
Neoplastic lesions of the parotid salivary gland can either be benign or malignant. Within the parotid gland, nearly 80% of tumours are benign. [17] Benign lesions tend to be painless, asymptomatic and slow-growing. The most common salivary gland neoplasms in children are hemangiomas, lymphatic malformations, and pleomorphic adenomas. [13]
Sialadenitis can be further classed as acute or chronic. Acute sialadenitis is an acute inflammation of a salivary gland which may present itself as a red, painful swelling that is tender to touch. Chronic sialadenitis is typically less painful but presents as recurrent swellings, usually after meals, without redness. [1]
Salivary gland dysfunction affects the flow, amount, or quality of saliva produced. A reduced salivation is termed hyposalivation . Hyposalivation often results in a dry mouth condition called xerostomia , and this can cause tooth decay due to the loss of the protective properties of saliva.
Pleomorphic adenomas may recur after a very long time from primary surgery, on average over 7–10 years and up to 24 years. [10] [11] Survival rates due to malignancy depends on the patient and extent of disease. [4] A 10-year survival ranges from 32-83%. [4] Of all cancers, salivary gland tumors account for only 1%. [4]
