“…The pathogenesis of facial nerve paralysis within the substance of the parotid gland has been discussed in many reports. 19,20 Kinking or stretching of the nerve, direct pressure on the nerve, or neurotoxic degeneration by local toxic factors from infection are seen as the most important contributors to neuronal dysfunction.…”

Necrotizing fasciitis (NF) is a very aggressive infection with associated high mortality. Risk factors of acquiring this infection may include diabetes mellitus, surgery, trauma, and infection. This infection necessitates prompt recognition and aggressive management in order to avoid its unfavourable outcomes. Associated nerve paralysis may indicate the involvement of deeper tissue. The present report highlights a case of cervical NF that was complicated by facial nerve paralysis, a feature that has rarely been reported.

“…The tenacity of the extratemporal portion of the nerve to withstand significant compression is borne out in a review of the literature describing benign tumors of the parotid gland that caused facial dysfunction. Twenty‐four cases reported in the literature were analyzed 60‐79 . Six patients had tumorous extension into the stylomastoid foramen, where the compressive effects can easily explain the onset of facial palsy.…”

Although the expansion properties of peripheral nerves have been a matter of considerable study in recent years, investigations of the plasticity of cranial nerves, including the facial nerve, have been lacking. Clinicians, however, have long recognized the tenacity of facial nerve function in patients with slow-growing benign tumors that enormously distort the nerve. An experimental study was designed to assess whether tissue expansion techniques can be applied to the extracranial portion of the facial nerves of cats. In eight cats the frontozygomatic branch of the facial nerve was expanded by stages in seven sessions over a period of 40 days. The length of the nerve increased an average of 95% without significantly impairing nerve function. Pressure changes in the expander averaged 75 mm Hg during each stage of expansion. Electroneurography was performed after each injection of the expander. Statistical analysis of these data did not show consistent evidence of demyelination or denervation, and all but one cat exhibited a normal blink reflex and had normal electromyographic findings at the end of the experiment. Histologic examination of the expanded nerves, however, did show inflammatory changes, intraneural edema, and occasional demyelination.

This paper presents a retrospective study carried out on a sample of 100 patients affected by pleomorphic adenoma of the parotid gland and treated at the Department of Maxillofacial Surgery at the University of Rome "La Sapienza" between January 1, 1989 and December 31, 1997. For the diagnosis of this neoformation, cytological tests were performed on material taken from the neoformation using fine needle aspiration and ultrasound scan. In some selected cases, a CT examination of the head and neck with medium contrast or Nuclear Magnetic Resonance (NMR) was carried out. This study sets out to examine the most suitable treatment to be followed for the removal of the pleomorphic adenoma of the parotid gland. In 56 cases the patients underwent a superficial, conservative parotidectomy. Forty one patients had a total parotidectomy with the facial nerve left intact and one patient had a total parotidectomy where the marginal mandibular nerve of the facial nerve was damaged. The remaining two patients involved in the study were suffering from a recurrent pleomorphic adenoma and in these two cases a total parotidectomy was performed where the facial nerve was killed. The removal of the cranial nerve VII in these patients proved necessary because the nerve fibers had adhered to the surrounding scar tissue of the tumor, either after previous surgery or due to repeated chronic phlogosis of the gland.
