Epineurial Pseudocyst of the Intratemporal Facial Nerve: A Case Series Study.

OBJECTIVES: The goal of this case series was to describe the clinical and radiological characteristics of epineurial pseudocysts of the intratemporal facial nerve (EPIFs) and to discuss the relevance in clinical practice. MATERIALS AND METHODS: A retrospective case series of 10 consecutive patients with EPIFs identified through computed tomography (CT), between 2009 and 2018. Morphological characteristics, coexisting pathology, facial nerve function, and evolution over time were analyzed. RESULTS: A unilateral EPIF was found in 5 patients (50%) and a bilateral EPIF was found in the other 5 (50%). The largest dimensions were observed in the coronal plane, with an average craniocaudal length of 6.0 mm (range, 3-9 mm). None of the patients presented with facial nerve dysfunction. Growth could not be observed in any of the patients. In 5 cases (33.3%), CT imaging showed a reduced transmastoid access to the facial recess caused by the EPIF. CONCLUSION: All EPIFs in this study were incidental findings. Facial nerve function was normal in all patients. Knowledge of EPIFs is important to perform safe cholesteatoma and cochlear implant surgery and to prevent unnecessary follow-up imaging.

A simple surgical technique for tracheoesophageal fistula closure.

Placement of a voice device in a tracheoesophageal fistula provides successful speech rehabilitation after total laryngectomy. However, in the long term, removal of the voice device and permanent closure of the fistula is sometimes necessary. This paper presents and evaluates a simple surgical technique for primary closure of tracheo-esophageal fistulae. We retrospectively review 12 laryngectomees who received this technique of primary closure from 1997 to 2000. In 58% of the patients, permanent fistula closure could be obtained. Six patients (50%) healed primarily; in one patient (8%) the residual fistula opening healed secondarily. Four patients (33%) needed a second surgical procedure, and in one patient (8%) inserting a new speech prosthesis obliterated the residual fistula. Radiotherapy seems to compromise wound healing and therefore may be considered as a contraindication. Complications such as tracheal stenosis, tissue necrosis and pneumonia, etc., did not occur.
