Abstract

Objective A novel local contralateral superiorly based mucoperiosteal nasal septal flap (CSBMNSF) for closure of a cerebrospinal fluid (CSF) leak from the middle anterior base of the skull is described. Materials and Methods A retrospective review of patients having endoscopic sinus surgery (ESS) with a CSF leak between 2000 and 2009 was performed. The surgical technique is described. Two vertical parallel incisions are performed anteriorly and posteriorly in the contralateral septal mucosa, joined inferiorly by a horizontal incision. Elevation of the flap is completed, leaving it pedicled superiorly. A window is created at the highest aspect of the nasal septum to allow transfer of the flap to the affected side. Results Four patients with a CSF leak post-ESS for excision of a congenital meningocele, tumor removal, and chronic sinusitis are described. All were treated successfully using a CSBMNSF. Conclusion A novel, easy-to-handle local flap for closure of defects in the anterior middle skull base is described. The use of this flap offers less morbidity and less bulkiness compared with other local or regional flaps.
