Peripheral Facial Palsy (peripheral + facial_palsy)
Selected AbstractsPrimary Ewing sarcoma of the petrous temporal bone: An exceptional cause of facial palsy and deafness in a nurslingHEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 10 2006Jens Pfeiffer MD Abstract Background. Primary Ewing sarcoma affecting the skull base in general and the petrous bone in particular is extremely rare with only 4 reports of Ewing sarcoma arising in the petrous temporal bone in the international medical literature. Methods. The authors report for the first time a case of a primary Ewing sarcoma of the petrous temporal bone in a 5-month-old nursling, which became apparent with a complete peripheral facial palsy and ipsilateral surdity. Results. The neoformation was treated by systemic chemotherapy and radiation of the tumor region. The diagnostic steps, therapy, and development of the child are described in detail; the literature concerning Ewing sarcoma originating from the skull in general and from the petrous temporal bone in particular is reviewed. Conclusions. The highlights of this case are an extremely uncommon location, an unusual age of presentation, as well as a unique set of symptoms. © 2006 Wiley Periodicals, Inc. Head Neck, 2006 [source] Movement disorders in patients with peripheral facial palsy,MOVEMENT DISORDERS, Issue 12 2003Josep Valls-Solé MD Abstract Acute unilateral facial paralysis is usually a benign neurological condition that resolves in a few weeks. However, it can also be the source of a transient or long-lasting severe motor dysfunction, featuring disorders of automatic and voluntary movement. This review is organized according to the two most easily recognizable phases in the evolution of facial paralysis: (1) Just after presentation of facial palsy, patients may exhibit an increase in their spontaneous blinking rate as well as a sustained low-level contraction of the muscles of the nonparalyzed side, occasionally leading to blepharospasm-like muscle activity. This finding may be due to an increase in the excitability of facial motoneurons and brainstem interneurons mediating trigeminofacial reflexes. (2) If axonal damage has occurred, axonal regeneration beginning at approximately 3 months after the lesion leads inevitably to clinically evident or subclinical hyperactivity of the previously paralyzed hemifacial muscles. The full-blown postparalytic facial syndrome consists of synkinesis, myokymia, and unwanted hemifacial mass contractions accompanying normal facial movements. The syndrome has probably multiple pathophysiological mechanisms, including abnormal axonal branching after aberrant axonal regeneration and enhanced facial motoneuronal excitability. Although the syndrome is relieved with local injections of botulinum toxin, fear of such uncomfortable contractions may lead the patients to avoid certain facial movements, with the implications that this behavior might have on their emotional expressions. © 2003 Movement Disorder Society [source] Electrodiagnostic studies of the facial nerve in peripheral facial palsy and hemifacial spasm,MUSCLE AND NERVE, Issue 1 2007Josep Valls-Solé MD Abstract Electrodiagnostic (EDX) assessment is one of the most important aspects in the evaluation of the two most common disorders of the facial nerve: facial palsy and hemifacial spasm. Facial palsy is usually an acute disorder that resolves in a few weeks but, in a number of cases, leads to a postparalytic facial syndrome featuring muscle synkinesis, myokymia, and involuntary mass contractions of muscles on the affected side. Hemifacial spasm is usually a chronic disorder characterized by paroxysms of involuntary, clonic, and synchronous twitching of all facial muscles on the affected side. EDX studies provide information on lesion location and severity, pathophysiology underlying the two disorders, and differential diagnosis between syndromes presenting with abnormal facial muscle activity. This monograph is intended to describe the most relevant EDX findings in the two disorders and the most appropriate timing for the examinations in order to provide useful information for prognosis and therapeutic decision-making.
