The human adult parotid duct is the longest of all major salivary gland ducts, approximately 6-8 cm in length. Its unique structure extends over the masseter muscle, penetrates through the buccinator muscle and opens into the oral cavity. Salivary secretion is under basic control of the sympathetic and parasympathetic divisions of the autonomic nervous system. Scarce reporting on the parotid du...

Parotid swelling is a common presentation in ENT clinic. Most of the cases involve pathology of the gland. There are not many reported cases about parotid duct pathology. We describe a case of a large parotid duct mucocele with a calculus. Excision of the mucocele and superficial parotidectomy was performed. The post-operative recovery was uneventful.

PURPOSE To revisit and reintroduce sialography as an important tool for the assessment and diagnosis of salivary gland obstruction. PATIENTS AND METHODS A sample of 30 consecutive patients undergoing sialography was selected. Parotid sialography was performed in 22 patients (12 females and 10 males). The patients undergoing parotid sialography presented with bilateral or unilateral enlargemen...

OBJECTIVES To define (1) at-risk structures during the orthodromic temporalis tendon transfer and (2) achievable tendon length without temporal releasing incisions or perioral lengthening materials. METHODS Ten fresh cadavers provided 20 hemifaces for dissection. Measurements and photographic documentation were used to examine the parotid duct, masseteric artery, inferior alveolar nerve, inte...

The present study was aimed to elucidate gross, histomorphological and histochemical status in parotid salivary gland of buffalo during neonatal life. The study was carried out on parotid salivary gland of eighteen buffalo neonates. These neonates were categorized into three groups based on their age, viz., Group-1: <1 month; Group-2: between1-2 months and Group-3: between 2-3 months. Macroscop...

Congenital absence or rudiment major salivary glands, especially of the parotid glands, are a rare entity. Aplasia of parotid glands has been described alone or in association with abnormalities of other salivary glands, first branchial arch developmental disturbances and other congenital anomalies such as lacrimoauriculodentodigital syndrome, mandibulofacial dysostosis and ectodermal dysplasia...

PURPOSE To investigate the feasibility of parotid duct transposition after tympanic neurectomy to treat severe keratoconjunctivitis sicca (KCS) in rabbits. METHODS Thirty rabbits were divided into three groups in experiment 1. One eye was operated on, and the contralateral eye served as the control. In the KCS group, the lacrimal gland, harderian gland, and nictitating membrane were removed. ...

A 3-year-old French bulldog presented for evaluation of recurrent swelling and a fistula on the right cheek after a dog fight. A large volume of serous fluids was identified on the wound immediately after atropine drops. A diagnosis of parotid salivary duct rupture secondary to trauma was made. On surgical exploration, the thickened proximal segment of the severed duct was identified and circum...

The antibody response of Macaca fascicularis in parotid saliva and serum to local immunization by two routes with Streptococcus mutans was studied and compared over 1 year. Antibodies were titrated and classified by indirect immunofluorescent staining using specific antiglobulin conjugates. Antiglucosyltransferase activity was assayed by an enzyme inhibition test. Animals were immunized first b...

Duct-associated lymphoid tissue (DALT) of the main excretory duct in the monkey parotid gland was first demonstrated by light microscopy and by transmission and scanning electron microscopy. The DALT included a follicular area, a parafollicular area and a specialized overlying epithelium with distinct fine-structural elements. There was usually a solitary lymphoid follicle located in the subepi...
