1/3. Salivary duct carcinoma of the parotid gland: a case report.The authors report a case of a salivary duct carcinoma (SDC) of the parotid gland revealed by a facial palsy. The clinical and pathological features of this highly malignant neoplasm are described. The aggressive nature of this form demands a combined chemo-radio-surgical treatment; only early recognition and treatment are likely to result in a favourable outcome.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
2/3. facial paralysis caused by malignant skull base neoplasms.OBJECT: bell palsy remains the most common cause of facial paralysis. Unfortunately, this term is often erroneously applied to all cases of facial paralysis. methods: The authors performed a retrospective review of data obtained in 11 patients who were treated at a university-based referral practice between July 1988 and September 2001 and who presented with acute facial nerve paralysis mimicking bell palsy. All patients were subsequently found to harbor an occult skull base neoplasm. A delay in diagnosis was demonstrated in all cases. Seven patients died of their disease, and four patients are currently free of disease. CONCLUSIONS: Although bell palsy remains the most common cause of peripheral facial nerve paralysis, patients in whom neoplasms invade of the facial nerve may present with acute paralysis mimicking bell palsy that fails to resolve. Delays in diagnosis and treatment in such cases may result in increased rates of mortality and morbidity.- - - - - - - - - - ranking = 6keywords = neoplasm (Clic here for more details about this article) |
3/3. Delayed presentation of traumatic facial nerve (CN VII) paralysis.facial nerve paralysis (Cranial Nerve VII, CN VII) can be a disfiguring disorder with profound impact upon the patient. The etiology of facial nerve paralysis may be congenital, iatrogenic, or result from neoplasm, infection, trauma, or toxic exposure. In the emergency department, the most common cause of unilateral facial paralysis is Bell's palsy, also known as idiopathic facial paralysis (IFP). We report a case of delayed presentation of unilateral facial nerve paralysis 3 days after sustaining a traumatic head injury. Re-evaluation and imaging of this patient revealed a full facial paralysis and temporal bone fracture extending into the facial canal. Because cranial nerve injuries occur in approximately 5-10% of head-injured patients, a good history and physical examination is important to differentiate IFP from another etiology. Newer generation high-resolution computed tomography (CT) scans are commonly demonstrating these fractures. An understanding of this complication, appropriate patient follow-up, and early involvement of the Otolaryngologist is important in management of these patients. The mechanism as well as the timing of facial nerve paralysis will determine the proper evaluation, consultation, and management for the patient. patients with total or immediate paralysis as well as those with poorly prognostic audiogram results are good candidates for surgical repair.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
