title: [Clinical and pathological observation of recurrent nasal polyp formation].
abstract: To investigate the mechanism of nasal polyp recurrence, 19 patients with recurrent nasal polyp were retrospectively analysed. In 4 patients, nasal polyp specimens had been sent for pathological examination more than three times, and in 6 patients, bacteria culture was performed. There were two types of recurrent nasal polyp: water-cyst type (fast recurrence) and edematous granulation type (slow recurrence). Both types were the result of inflammatory reaction, perhaps related to trauma of operation. Water-cyst formation indicated stronger inflammatory reaction. During follow-up, 10 patients were cured and 9 recurred. Preventive measures against nasal polyp recurrence were discussed.
