We investigated how a new type of synthetic porous hydroxyapatite ceramic (HAP-TCP) acts when it is implanted in growing membranous bone. Seventy-six New Zealand White infant male rabbits (4-week-olds) were used. Rabbits received HAP-TCP block or silicone block implantation in their right nasal bone. The left nasal bone was used for a sham. Serial or cross-sectional examinations by morphometry,...

In a prospective survey, 200 cases of operated chronic dacryocystitis were divided into three groups according to the kind of operation, and the respective results are as follows: Group I includes 100 cases in whom the lacrimal bone was removed (8mm x 8mm) and a 6mm diameter catheter was used (as a duct between the lacrimal sac and nasal cavity). The recurrence rate within one year was 24 ...
