[Intraoral application of vacuum-assisted closure in the treatment of an extended mandibular keratocyst]. / Intraorale Vakuumtherapie zur Behandlung einer ausgedehnten Zyste des Unterkieferknochens.

ABSTRACT

In extended cysts of the jaw bone particular demands are made in terms of wound closure, especially if an intraoral surgical approach is chosen. A tight closure is even more important if the bony defect has been filled with an alloplastic material or autologous cancellous bone. In our case a keratocyst of the left mandibular angle and ascending ramus was treated. After enucleation of the cyst and grafting with autologous cancellous bone the graft was lost following a wound breakdown. Subsequently a system was developed to apply intraoral V.A.C.-therapy. This led to a safe separation of the cystic defect and the oral cavity and a conditioning of the wound ground. A grafting with an alloplastic material was carried out successfully. With this method the length of treatment could be reduced by several months compared to a conventional therapy with an obturator.
