Abstract:

According to the morphologic observation of parotid glands of 88 cadevers of adults.It's obvious that:①The parotid gland is of different shapes and sizes,including irregular triangularshape,irregular quadrilateral-shape,strawberry-shape,wing-shape and hoof-shape.②The parotid gland has many processes,such as duct process,temporal process,inferior process,processus mastoideus, pterygo-mandibular process, parapharyngeal process and tympano-mandibular process.The amount of processes and the degree of development are related to the shape of parotid gland.③The original site,length and superficial projection of parotid duct are related to the shape of parotid gland.The horizontal line from the lower brim of auricular lobule to the line which goes from mandibular angle to the peak point of zigomatic can be regarded as the superficial projection of parotid duct.④The accessory parotid gland occurs separately.Its duct joins in the parotid duct by acute angle.

Key words: morphology of parotid gland, parotid duct, accessory parotid gland, process of porotid gland
