Tissucol in closure of oroantral communication. A pilot study.

Complete closure of oroantral communication was achieved in 16 out of 17 patients using a single application of Tissucol. The wound healing was uneventful. The need of inserting the sealant mixture above the floor of the antrum in order to protect the clot from air flow was pointed out. Tissucol was safely applied even in cases with severely damaged buccal or palatal mucosa or after a failure of the buccal sliding flap technique.
