Facial nerve tumors are a very uncommon neoplasm. They may originate from any segment of the VIIth nerve, from the cerebellopontine angle to the peripheral branch in the parotid gland. Because of lack of specific clinical symptoms, diagnosis may be difficult. Small facial tumors may also remain asymptomatic and only be discovered incidentally. Reports of tumor excision in which the nerve is lef...

Facial nerve schwannomas (FNS) are encapsulated benign tumors arising from Schwann cells of seventh cranial nerve. Most of the facial nerve schwannomas are localized in intratemporal region; only 9% of cases involve a portion of the extratemporal segment. Preoperative diagnosis is often unclear; diagnosis is often made intraoperatively. Management of intraparotid FNS is troublesome because of t...

Electrophysiological studies of a patient with cephalic tetanus, manifested by trismus and unilateral facial palsy, revealed that the trismus resulted from strictly unilateral masseter spasm which stopped during sleep, a normal silent period in the involved masseter muscles, initially prolonged distal latency of the paretic orbicularis muscles, and abnormal continuous muscle activity in the par...

(1) The application of the Nissl method to the study of the motor cells of the spinal cord, and the nerve cells of the dorsal root ganglia in typhoid fever, shows that these cells regularly suffer pathological changes in the course of the infection. (2) The alterations in the motor cells are more constant and of a severer grade than are those in the cells of the sensory ganglia. The more charac...

UNLABELLED This study provides morphometric data on radiation-induced alterations of the facial nerve in female Wistar rats. The facial nerves were explanted 3 to 4 or 7 to 9 months after completion of a fractionated external irradiation of the left side of the neck (5 days per week, 6 weeks, total: 60 Gray). Both facial nerves were investigated in order to identify possible effects of scattere...

OBJECTIVES To study the correlation between Sunnybrook and House-Brackmann facial grading systems at different time points during the course of peripheral facial palsy. STUDY DESIGN Prospective multicenter trial. SETTING Seventeen otorhinolaryngological centers. SUBJECTS AND METHODS Data are part of the Scandinavian Bell's palsy study. The facial function of 1920 patients with peripheral ...

OBJECTIVES To investigate the effects of injection of botulinum toxin type A (BTX A) into the orbicularis oculi muscle and lacrimal gland in patients with aberrant regeneration after facial palsy (facial synkinesias and hyperlacrimation). METHODS The effect of the toxin injection (on average 75 mouse units of BTX A) into the orbicularis oculi muscle on facial synkinesias was assessed on a fiv...

BACKGROUND Facial pain occurring after traumatic injury of the facial branches of the trigeminal nerve is a medical condition that is often very difficult to treat. Patients are quite disabled by their symptoms and most therapies are ineffective in relieving this pain. Peripheral nerve stimulation has been used as a treatment to provide pain relief for this type of intractable atypical facial p...

Introduction Localized Scleroderma (LS) has been associated with central and peripheral nervous system involvement. Facial palsy, extra-ocular movement disorders, trigeminal neuralgia and hemi-masticatory spams are described as primary neurologic involvement. Romberg hypothesized that sympathetic regulation has pathogenic relevance in facial hemiatrophy, which was reproduced experimentally by s...

Bell's Palsy is the sudden onset of unilateral temporary paralysis of facial muscles resulting from seventh cranial nerve dysfunction. Presented here is a two-year old female patient with right peripheral facial palsy following hepatitis B vaccination. Readers' attention is drawn to an uncommon cause of Bell's Palsy, as a rare complication of hepatitis B vaccination.
