[Nasal endoscopic surgical treatment for chondrosarcoma of paranasal sinus and the skull base].

OBJECTIVE

To discuss the clinical characteristics and treatments for chondrosarcoma of paranasal sinus and the skull base.

METHODS

The clinical characteristics of chondrosarcoma of paranasal sinus and skull base in 7 patients underwent endoscopic surgeries between 2001 and 2008 were analyzed. Of the patients, 4 men and 3 women. The patients' age ranged from 18 to 47 years, with a median of 31 years.

CLINICAL SYMPTOMS

stuffy, nose bleeding, runny, headache, diplopia, eye outreach limited, blurred vision and even blindness. Surgery methods: under nasal endoscopy, after the attachment sites of the tumors to normal tissues were confirmed, the tumors were peeled off along the clear boundary between the tumors and normal tissues, and the potential residual tumor tissues on bones were cleared by a drill.

RESULTS

The patients were followed up postoperatively for 24 to 108 months, with a median of 36 months. Five of 7 patients were no recurrence, 2 were alive with tumor.

CONCLUSIONS

Chondrosarcoma of paranasal sinus and skull base can be treated by nasal endoscopic surgery, with good clinical outcome.
