Laryngoscopic diagnosis of laryngeal sarcoid.

Sarcoidosis is usually a multisystem granulomatous disease, and it sometimes affects the larynx and causes symptoms of dysphonia, dyspnea, and dysphagia. Laryngeal sarcoid has a characteristic appearance at direct or indirect laryngoscopy: the supraglottic tissues are symmetrically affected with a pale, diffusely swollen appearance somewhat like that of epiglottitis. Five cases of laryngeal sarcoid are presented. Three photographs taken at direct laryngoscopy, and one at indirect laryngoscopy, document and emphasize the typical appearance of the supraglottic tissues. The appearance of this uncommon condition is sufficiently characteristic to suggest the diagnosis, which can finally be confirmed only by biopsy.

Grading facial nerve function: House-Brackmann versus Burres-Fisch methods.

Many systems for reporting results of facial function tests have been proposed, but after five International Facial Nerve Symposia, a perfect system for reporting has yet to be developed. In 1985 the American Academy of Otolaryngology-Head and Neck Surgery adopted the House-Brackmann (H-B) six-point subjective grading scale as a universal standard. This decision was based on the recommendation of the Facial Nerve Disorders Committee. The next year, 1986, Burres and Fisch proposed the Linear Measurement Index (B-F LMI) as an alternative, objective grading system. To determine the ability of each system to grade the facial function of patients with facial palsy, and the relative merits of each system, 41 patients with facial weakness and one normal patient were studied. The H-B grading system is easy to use and provides simple, concise criteria for each separate grade of facial function. The B-F LMI grading system is time-consuming and labor-intensive, and requires a complex calculation to derive a percentage value that represents facial function. The most important finding of this study was the high degree of correlation between the two systems, in spite of the fact that the H-B system is subjective and qualitative while the B-F LMI system is objective and quantitative. Until the perfect grading system is developed, the authors favor combining the H-B and B-F LMI systems as the best method available at the moment to evaluate facial function.

Non-Hodgkins lymphoma of the temporal bone.

The temporal bone may be involved by primary or secondary neoplasms. The latter are uncommon but well documented in the literature, the usual primary sites being breast, kidney, lung, stomach, larynx and prostate (Schuknecht et al., 1968). Lymphoma rarely invades the temporal bone and is usually confined to the lymphoreticular system and gastrointestinal tract. A case of non-Hodgkins lymphoma of the temporal bone is presented.

Vocal cord granulomas.

A series of 16 vocal cord granulomas in adults and children were studied; of these, seven occurred postintubation. All granulomas were removed at least once and the recurrence rate was high. On average, there were three removals, and some patients are still under observation. The recurrence rate did not seem to be related to removal by surgical excision or by laser. We postulate, contrary to conventional teaching, that vocal ulcer and vocal cord granuloma should be regarded as separate entities which occur at the same anatomical site.

Vocal nodules in children.

We reviewed 27 pediatric patients who had vocal nodules removed surgically in a 5-year period. Age of operation, duration of symptoms, indications for operation, and the results of removal are analyzed. The techniques of laryngoscopic assessment with telescopes and of microsurgical removal are described in detail. The 27 children had 53 nodules removed. Almost all had normal or improved voices as judged by the parents' answers to a written questionnaire. From the results of this series, microsurgical removal of vocal nodules in children is justified in selected patients.
