NCT00422136

Brief Summary

The goal of this study is to identify the genes that contribute to susceptibility to recurrent/persistent middle ear disease. Five hundred families with at least 2 children who have undergone tympanostomy tube insertion will be enrolled. A blood sample will be obtained from the children who had tubes and any available parent (at least 1), as well as any siblings without significant histories of middle ear disease.
