Pneumoparotitis is often misdiagnosed and incorrectly managed. [5] The diagnosis is based mainly on the history. [1] Crepitus may be elicited on palpation of the parotid swelling, [1] and massaging the gland may give rise to frothy saliva or air bubbles from the parotid papilla. [1]
The parotid glands are a pair of mainly serous salivary glands located below and in front of each ear canal, draining their secretions into the vestibule of the mouth through the parotid duct. [3] Each gland lies behind the mandibular ramus and in front of the mastoid process of the temporal bone .
HIV parotitis: Generalized lymphadenopathy has long been associated with HIV, but the localized enlargement of the parotid gland is less well known. [citation needed] HIV-associated salivary gland disease can involve many diseases but often presents as enlargement of the parotid gland and a dry mouth. Causes have not been specifically ...
The parotid duct is formed when several interlobular ducts, the largest ducts inside the parotid gland, join.It emerges from the parotid gland. It runs forward along the lateral side of the masseter muscle for around 7 cm. [2] In this course, the duct is surrounded by the buccal fat pad.
The submandibular duct (also Wharton's duct or historically submaxillary duct) is one of the salivary excretory ducts. It is about 5 cm long, and its wall is much thinner than that of the parotid duct. It drains saliva from each bilateral submandibular gland and sublingual gland to the sublingual caruncle in the floor of the mouth.
The great auricular nerve is a cutaneous (sensory) nerve of the head. It originates from the second and third cervical (spinal) nerves (C2-C3) of the cervical plexus.It provides sensory innervation to the skin over the parotid gland and the mastoid process, parts of the outer ear, and to the parotid gland and its fascia.
The salivary glands in many vertebrates including mammals are exocrine glands that produce saliva through a system of ducts. Humans have three paired major salivary glands (parotid, submandibular, and sublingual), as well as hundreds of minor salivary glands. [1] Salivary glands can be classified as serous, mucous, or seromucous (mixed).
The preauricular deep parotid lymph nodes (anterior auricular glands or preauricular glands), from one to three in number, lie immediately in front of the tragus. Their afferents drain multiple surfaces, most of which are lateral in origin.
