As 42-year-old woman complaining of swelling in the left parotid gland region for past two years, was admitted in our department for surgery in June 1979. By bimanual palpation, we suspected a left parotid gland tumor which extended into the parapharyngeal space. This diagnosis was confirmed by the aids of sialography and CT scanning. As surgical procedure, we chose an external approach and could remove a "Dumb-bell type" mixed tumor without injuries of the facial nerve and palatal mucosa. From the experiences of this case and other two cases treated before in our department, discussions were made on the diagnosis and surgical treatment for this sort of tumor of the parotid gland.Clinical and surgical findings of a 42-year-old woman, who complained of swelling of the parotid gland region of the left side and showed a dumb-bell type of the mixed tumor, were discussed with the emphasis on the following points:(1) For the detection of a dumb-bell type of the parotid gland tumor, bimanual palpation of the tumor is useful. Furthermore, CT scanning is also useful for the detection not only of the tumor of this type but also of its extending to the parapharyngeal space.(2) Among various surgical methods of a dumb-bell type of the tumor, external approach seems most suitable, since injuries of the vessels of the parotid gland, palatanal mucosa and facial nerves can be avoided when this approach is adopted.
