Free Mucosal Graft for Reconstruction after Nonfunctional Pituitary Adenoma Surgery.

Background: In the search for an effective closure without nasosinusal morbidity, we have studied the efficacy of free mucosal graft as a reconstructive technique of the sellar floor after the resection of nonfunctioning pituitary adenomas (NFPA).

Methods: In 100 endonasal endoscopic surgeries, we analyzed the personal history, radiological and intraoperative aspects that could have an impact on the risk of postoperative cerebrospinal fluid (CSF) leak. They were divided into three groups: no mucosa flap/graft, mucosal free graft, and nasoseptal pedicled flap.

A new entity in the differential diagnosis of geniculate ganglion tumours: fibrous connective tissue lesion of the facial nerve.

Differential diagnosis of geniculate ganglion tumours includes chiefly schwannomas, haemangiomas and meningiomas. We report the case of a patient whose clinical and imaging findings mimicked the presentation of a facial nerve schwannoma.Pathological studies revealed a lesion with nerve bundles unstructured by intense collagenisation.
