| parotid abscess | Rapidly progressive suppuration in the parotid gland; a complication of parotitis. (05 Mar 2000) |
|---|---|
| parotid bed | The structures which surround and contact the parotid, forming the boundaries of the parotid space: anteriorly, the ramus of the mandible flanked by the masseter and medial pterygoid muscles; medially, the pharyngeal wall, carotid sheath and structures originating from the styloid process; posteriorly, the mastoid process, sternocleidomastoid muscle, and posterior belly of the digastric muscle; superiorly, the temporomandibular joint and the tympanic bone and cartilaginous portion of the external acoustic meatus. (05 Mar 2000) |
| parotid branches | Branches to parotid gland; Nomina Anatomica lists parotid branches of 1) auriculotemporal nerve (rami parotidei nervi auriculotemporalis; 2) facial vein, rami parotidei venae facialis; 3) superficial temporal artery, ramus arteriae temporalis superficialis. Synonym: rami parotidei. (05 Mar 2000) |
| parotid duct | The duct of the parotid gland opening from the cheek into the vestibule of the mouth opposite the neck of the superior second molar tooth. Synonym: ductus parotideus, Blasius' duct, Stensen's duct, Steno's duct. (05 Mar 2000) |
| parotid fascia | The part of the investing cervical fascia that ensheaths the parotid gland and is fixed above to the zygomatic arch. Synonym: fascia parotidea, fibrous capsule of parotid gland, parotid sheath. (05 Mar 2000) |
| parotid gland | <anatomy> A salivary gland situated in front of and below the ear. (27 Sep 1997) |
| parotid gland mass | <radiology> Pleomorphic adenoma, sialocele, adenoid cystic carcinoma, adenocarcinoma, lymphoma, lymph node, abscess, metastasis (12 Dec 1998) |
| parotid notch | The space between the ramus of the mandible and the mastoid process of the temporal bone. (05 Mar 2000) |
| parotid papilla | The projection at the opening of the parotid duct into the vestibule of the mouth opposite the neck of the upper second molar tooth. Synonym: papilla parotidea. (05 Mar 2000) |
| parotid recess | A deep hollow on the side at the sides of the face flanking the posterior aspect of the ramus of the mandible with its attached muscles which is occupied by the parotid gland; it is lined with fascial laminae (the parotid sheath) derived from the investing layer of deep cervical fascia; the structures bounding the space collectively constitute the parotid bed. Surgeons operating in the area take advantage of the fact that the anteroposterior dimensions of the parotid space increase with protrusion of the mandible. Synonym: parotid recess, recessus parotideus. (05 Mar 2000) |
| parotid sheath | The part of the investing cervical fascia that ensheaths the parotid gland and is fixed above to the zygomatic arch. Synonym: fascia parotidea, fibrous capsule of parotid gland, parotid sheath. (05 Mar 2000) |

Synonym: parotid recess, recessus parotideus. (05 Mar 2000) |
| parotid veins | Branches draining part of the parotid gland and emptying into the retromandibular vein. Synonym: venae parotidea, posterior parotid veins. (05 Mar 2000) |
| retromandibular process of parotid gland | That portion of the parotid salivary gland that is located behind the mandible and occupies the space between the ramus of the mandible and the mastoid process extending as far medially as the pharyngeal wall. Synonym: processus retromandibularis glandulae parotidis, processus retromandibularis. (05 Mar 2000) |
| mouse parotid tumour virus | <virology> A papovavirus (genus Polyomavirus, family Papovaviridae) which is a DNA tumour virus with very small genome. Polyoma was isolated from mice, in which it causes no obvious disease, but when injected at high titre into baby rodents, including mice, it causes tumours of a wide variety of histological types (hence polyoma). In vitro, infected mouse cells are permissive for virus replication and thus are killed, whilst hamster cells undergo abortive infection and at a low frequency become transformed. It is capable of producing parotid tumours in mice and sarcomas in hamsters as well as tumours in other laboratory animals. Synonym: mouse parotid tumour virus. (22 Sep 2002) |
