The purpose of this study was to evaluate the change in mucosal inflammation of the inferior turbinate and nasal structure of the parients with cleft lip and palate after secondary alveolar bone grafting by comparing the findings with those before treatment. The subjects were 13 patients with cleft lip and palate who underwent secondary alveolar bone grafting. Before and 5-6 months after the surgery, biopsy of the inferior turbinate of the operated side was performed and examined microscopically. The nasal cavity on the same side was also examined by nasoendoscopy. The results were as follows: 1) There was no relationship between the size of the oronasal fistula and the degree of mucosal inflammation of the inferior turbinate. 2) There was no relationship between the cleft type and the degree of mucosal inflammation of the inferior turbinate. 3) There was a correlation between the degree of mucosal inflammation of the inferior turbinate and the frequency of reducing the inferior turbinate. 4) The degree of inflammation of the inferior turbina te tended to reduce after bone grafting. 5) The nasoendoscopic findings revealed no abnormal nasal structure after bone gra fting. These results suggested that the nasal structure and inflammation of nasal mucosa improved by secondary alveolar bone grafting, and reducing inferior turbinate performed simultaneous with alveolar bone grafting has no adverse effect on nasal mucosa and structure.
