A man aged 42 years came to our clinic with anterior swelling in the middle of the neck. He had a large hemangioma of the tongue which was treated by both radiotherapy and surgery fifteen years ago. Some yellowish fluid was obtained on puncture and 38% Lipiodol was injected. X-ray examination demonstrated that the cyst extended to the posterior surface of the hyoid bone. According to Sistrunk's method, the cyst was completely extirpated with partial resection of the hyoid bone. Pathological examination was compatible with median cervical cyst. The cyst wall was chiefly lined with ciliated epithelium. The thyroglossal duct is either situated 1. in front of the hypid bone, 2. through the hyoid bone, or 3. behind the hyoid bone. For the purpose of prevention of recurrence, partial resection of the hyoid bone is necessary. The authors concluded that Sistrunk's method is most preferable.
The close co-operation of rhinologists and dentists is needed for the diagnosis of dental sinusitis. To evaluate the pathological condition, rhinologists are required to have a basic knowledge of odontology. We described the value of the intraoral roentgenograms in the diagnosis of dental sinusitis. Intraoral roentgenograms are most important in understanding the changes in teeth and surrounding structures in patients with dental sinusitis. The changes of teeth, supporting structures and floor of maxillary sinus could be classified as follows: 1. Standard type 2. Lower type 3. Lower type of apex area 4. Lower type of interradicular area 5. Indistinct type 6. Absorption type.
Isoproterenol has a potent dilating effect on the peripheral blood vessels. A total of 45 patient with vertigo were treated by three different methods with isoproterenol; in the first group by a combination of isoproterenol hydrochloride (10mg) and pronase 3.75mg (KIP-01); in the second group, isoproterenol hydrochloride only (10mg) (KIP-02) and in the third group by pronase (3.75 mg) (KIP-03). Improvement of subjective symptoms was seen in 86.7% in the first group, 66.7% in the second group and 53.3% in the third group. Objective improvement of the findings was seen in 73.3% in the first group, 66.7% in the second group and 20.0% in the third group. The results were tested statistically by x2 test, which showed no significant difference in alleviation of subjective symptoms but significant difference was demonstrated between the first group and the third group (1%), between the second group and the third group (5%) while no significant difference was seen between the first group and the second group. The results indicate that isoproterenol has beneficial effect on the control of vertigo.
