Mucosal prelaminated flaps for physiological reconstruction of intraoral defects after tumour resection.
In order to provide vascularised mucosa for reconstruction of intraoral defects after radical tumour resection, 5 distal radial forearm flaps and 1 fibula flap were prelaminated. Prelamination was performed by fixing small, full thickness mucosa pieces onto the fascia and covering the mucosa with an alloplastic sheet as large as the future flap. The alloplastic material was a silicone sheet (n = 2), a Gore-tex sheet (n = 3) or a titanium sheet (n = 1). The mucosa and the alloplastic material were covered by the skin and subcutaneous tissue which had been elevated to expose the fascia. With the silicone and titanium sheets, the mucosa spread on the fascia and the final flaps were thin, pliable, mucus-producing and larger than the original mucosa pieces. With the Gore-tex sheets, extension of the mucosa was prevented by adhesions and the area of mucosa on the final flap was the same size as the original graft. The six prelaminated flaps were harvested after 8-10 weeks. During this time the patients had radiotherapy and chemotherapy. Preserving the skin and subcutaneous tissue reduced donor site morbidity. Six patients had intraoral defects successfully reconstructed with mucus-producing prelaminated flaps.
