1/4. Simultaneous vocal fold and tongue paresis secondary to Epstein-Barr virus infection.dysphonia is a common presenting symptom in cases referred for otolaryngologic evaluation. Similarly, primary care physicians frequently see adolescents or young adults with symptomatic Epstein-Barr virus infection. Some of the patients with active Epstein-Barr virus infection who have severe clinical manifestations of infectious mononucleosis will be referred for otolaryngologic evaluation. Voice abnormalities in these patients, though, are usually limited to altered resonance due to pharyngeal crowding by hyperplastic lymphoid tissue. We describe a patient with infectious mononucleosis who was referred for evaluation of dysphonia and was diagnosed with unilateral tongue and vocal fold paresis. We also discuss the patient's clinical course and review the related literature. Although uncommon, cranial nerve palsies must be considered in the patient with Epstein-Barr virus infection who presents with voice or speech disturbance.

2/4. Vocal tremor reduction with deep brain stimulation: a preliminary report.Vocal tremor has been a challenging problem for patients and their physicians. In some cases, it has been possible to lesson the symptom's tremor through medications and/or voice therapy. However, in most cases no good treatment has been available. Chronic stimulation of the thalamus has been successful in controlling tremors of the upper limb and other portions of the body. Our preliminary experience suggests that it may also be helpful in controlling vocal tremor.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
3/4. Complications of collagen injection of the vocal fold: report of several unusual cases and review of the literature.Injection laryngoplasty is one of the most frequently performed procedures in patients with voice complaints. Various biomaterials have been used to medialize vocal folds or to treat symptoms of vocal fold scar. The ideal biomaterial would be easily injected through a fine-gauge needle, well tolerated, and long lasting. Injectable collagen preparations fulfill at least two of these criteria, and collagen has been used widely for vocal fold injections. MATERIALS AND methods: We present a retrospective review of two unusual complications of collagen injection and a review of the relevant literature on the complications of medical use of collagen compounds. RESULTS: Two patients in whom collagen was injected formed firm submucosal deposits that interrupted the normal mucosal wave and produced significant dysphonia. Surgical removal of these deposits restored the mucosal wave and improved voice quality. Management of this unusual complication of human collagen injection in the vocal fold has not been reported previously. Other complications of collagen injection include hypersensitivity reactions to bovine collagen, local abscess formation at injection sites, and possibly induction of collagen vascular disease in some patients. CONCLUSIONS: Although collagen injections of the vocal fold rarely result in complications, physicians using collagen must be familiar with the types of complications that can occur. Proper diagnosis and prompt management of complications can result in good outcomes.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
4/4. Semi-automated voice evaluation.This report describes a voice evaluation procedure that in some way parallels the audiologic tests used for hearing and has multiple uses both clinically and in research. It uses a simultaneous eight-channel input, is not difficult to use, requiring between 12 and 25 minutes to administer, and provides the physician with a printout in standardized form before the patient leaves the room. This three-page report includes 15 abstracted or calculated values, normal ranges by sex for each value, notes that draw attention to deviations from the normal, a summary profile, a graphic representation of the evaluation, and raw data waveforms.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
