Teflon injection for vocal cord paralysis after intracranial operation.

Vocal cord paralysis may follow intracranial operation if the vagus nerve is damaged intraoperatively. If the resulting laryngeal incompetence is severe, hoarseness, dysphagia, and aspiration may develop. This is often followed by a pneumonitis requiring chronic gastric tube feeding. Teflon vocal cord injection has been shown to restore the sphincteric action of the larynx and enable patients to phonate and swallow properly again. Nine patients underwent this procedure for chronic aspiration and hoarseness. All had vagus injury attributable to antecedent intracranial operation, and all experienced relief of their symptoms with only minor complications. Teflon vocal cord injection is advocated as a safe, effective means of managing patients with aspiration and dysphagia secondary to vagus nerve injury.

Trans-septal sphenoidotomy approach for cystic lesions of the clivus.

Destructive lesions of the clivus produce symptoms related to adjacent anatomic structures. Radiographic evaluation of a patient presenting with cranial neuropathies revealed a cystic lesion of the clivus, and surgical and histologic findings established a diagnosis consistent with a mucocele. There have been no previous reports in the literature describing a primary mucocele of the clivus. Appropriate treatment for these fluid-filled structures is marsupialization or exteriorization into the sphenoid sinus. A trans-septal sphenoidal approach was used in this case and is advocated as an effective means of managing cystic lesions in this area.

Evaluation of the frontonasal duct in frontal sinus fractures.

Successful management of frontal sinus fractures depends on correct identification of structural pathology, which may lead to inflammatory complications. Obstruction of the frontonasal duct is a significant factor predisposing to such complications and its evaluation is thus critical in the management of these fractures. Specific radiographic CT criteria and an intraoperative dye irrigation test are presented to determine the likelihood of frontonasal duct injury. Eighteen cases of frontal sinus fractures are reviewed, which have been treated based on these principles. A scheme is presented outlining the management of frontal sinus trauma using these methods.
