Neurophysiological monitoring of cranial motor nerves has proved to be of value in cerebellopontine and skull base surgery. Unfortunately, facial nerve monitoring has been used infrequently for routine parotid gland surgery because suspicion of expense, possible unreliability and the requirement for extra personnel. This study presents clinical experience at the University of Erlangen with facial nerve monitoring during parotid gland surgery done by residents. Advantages are also emphasized for the experienced ENT-surgeon for use during revision parotidectomy. In 35 consecutive patients with benign parotid gland tumors intraoperative monitoring of the facial nerve was done using two different two-channel electromyography units. Bipolar coaxial electrical stimulation was superior to the monopolar stimulation mode. The average operative time and postoperative functional results were compared with those of a control group consisting of 24 patients without monitoring. Findings demonstrated a reduction is operative time and better functional outcome in the patient group with monitoring. Additionally four patients had to undergo total revision parotidectomy because of recurrent benign tumors, while one patient suffered from chronic parotitis due to sialolithiasis and required complete parotidectomy for relief of symptoms. No patient developed permanent facial paresis and nerve monitoring proved to be very helpful for identification and protection of the facial nerve in scar tissue.

This is a case report of the 2nd oldest patient reported in the literature with transverse myelitis after mumps, and the 1st with magnetic resonance imaging (MRI) correlation. He is a 38-year-old Chinese man presenting with bilateral lower limb weakness and numbness, and urinary retention starting 3 weeks after an attack of mumps parotitis. Clinically, there was mild lower limb paresis, absent plantar responses and reduced pain sensation below the umbilicus. MRI revealed cord swelling and increased T2 signal from T7 to T11. Cerebrospinal fluid showed 23 cells/mm3 and 55 mg protein/dl. He received a 5-day course of intravenous methylprednisolone 0.5 g/d. The sensory and motor deficits improved over 2 weeks; urinary symptoms improved over the next year. Transverse myelitis following mumps is recognizable clinically and radiologically, and potentially responsive to methylprednisolone.

Nonmalignant parotid masses in children can have protean etiologies ranging from infective parotitis to a benign neoplastic, vascular, or congenital origin. We review the 10-year experience of a tertiary care pediatric centre with respect to the surgical management of nonmalignant parotid masses. In total, 15 patients with nonmalignant masses of the parotid gland region underwent surgery. Five children were diagnosed with lymphoepithelial cyst or first branchial cleft cyst. Three children were diagnosed with parotid abscess, one of whom had atypical mycobacteria. Other diagnoses included lymphangioma (three cases), chronic inflammation (two cases), and epidermoid cyst (one case). One patient who presented with a parotid cyst was diagnosed postoperatively with plexiform neurofibroma of the facial nerve. She was the only patient with postoperative facial nerve paresis, affecting the orbital branch. Presentation and postoperative complications of these surgically managed nonmalignant parotid masses are reviewed. The history and physical examination are of the utmost importance in predicting the diagnosis, although ultrasonography and computed tomography can be useful. Fine-needle aspiration cytology was not well tolerated by children and appears of little use as the accurate diagnosis was provided by the surgical pathology specimen.
