AIMS
To analyse bone
fragments from rhinostomies of patients undergoing revisional
dacryocystorhinostomy, looking for evidence of new bone formation.
METHODS
14 consecutive
patients undergoing secondary lacrimal surgery were included in this
study. In each case the existing rhinostomy was enlarged with bone
punches, care being taken to use the punches with the jaws cutting
perpendicularly to the edge of the rhinostomy, to allow accurate
orientation of the specimens. The fragments were examined
histologically for evidence of new bone formation.
RESULTS
Histological
sections showed fragments of bone with variable fibrosis at the edge of
the rhinostomy. There was evidence of only very little new bone formation.
CONCLUSION
This study
has clearly shown that, at the edge of a rhinostomy, healing is
predominantly by fibrosis and there is only very limited new bone formation.
