手術治療を行った副鼻腔の線維性骨異形成症・骨腫症例の臨床的検討

抄録

The postoperative courses of seven patients with fibrous dysplasia and four patients with osteoma in the paranasal sinuses were observed clinically. The period of the observation was from 1.5 years to 10 years. The subjective symptoms had been improved in all cases. The postoperative enlargements or recurrences of tumor in each case except for two cases of fibrous dysplasia were evaluated by X-ray findings of the paranasal sinuses. The enlargements of the tumor were found in four cases of fibrous dysplasia who had been operated on before 18 years old. Although the rests of tumor at the operation were found in a 34-year-old case of fibrous dysplasia and 23, 29, 58-year-old cases of osteoma, the postoperative enlargements of tumor were not found in these cases. The recurrence of tumor was not found in a 49-year-old case whose osteoma had been removed completely.
The operation of fibrous dysplasia in the paranasal sinuses should be performed by taking age of the patient into account. When the patients with fibrous dysplasia and osteoma are operated, especially before adolescence, the postoperative course should be observed carefully and for along time.
