Observations on so-called idiopathic vocal cord paralysis.

A series of 238 patients with laryngeal paralysis seen during a six-year period (1976-1982) were studied with serial 16-mm motion picture filmstrips. There were 39 cases in which no etiological disease process could be found responsible for the paralysis; these were called "idiopathic." In all 39 cases, both the superior and recurrent laryngeal nerves were paralyzed indicating that the lesion involved the central (nuclear) lower motor neurons of the dorsal and ventral nucleus ambiguus. The high incidence of upper respiratory infections suggests a viral etiology in many cases. The ability to separate a pure recurrent from a combined superior and recurrent laryngeal paralysis on morphological indirect endoscopic appearance has significant diagnostic and therapeutic implications.

Contact ulcers and granulomas of the larynx: new insights into their etiology as a basis for more rational treatment.

Repeated analysis of cinephotographic and cinefluorographic studies, correlated with clinical observations, has helped elucidate the causes of contact ulcers. Habitual throat clearing, excessive glottic attack in initiation of speech, and, most important, acid regurgitation secondary to hiatal hernia are the causal factors of contact ulcers. Contact granulomas produced by intubation trauma and other granulomas are compared and discussed. The successful treatment of contact ulcers and granulomas is dependent on elimination of vocal abuse, cessation of throat clearing, and control of the factors that cause the irritation and throat clearing.

Photographic studies of the larynx in central laryngeal paresis and paralysis.

Characteristic patterns of laryngeal dysfunction due to central neurologic disease are documented by 16 mm ciné photography. Representative patients are used to describe typical patterns of abnormal laryngeal function which occur in upper motor neuron, extrapyramidal, cerebellar, nuclear and mixed foci of lesions. The pitfall of brief indirect laryngoscopy without visual documentation is emphasized as a factor in misdiagnosis of patients with laryngeal disease of central origin. The value of more careful evaluation of similar patients is emphasized in relation to better understanding of laryngeal function and improved patient care.

Improving radiology in surgery.

The time has come to reevaluate the use of films of substandard quality obtained from outdated radiography equipment. The authors recommend that surgical subspecialists, orthopedic surgeons, emergency room physicians, gastroenterologists, or whoever employs radiology in the operating room ensure that technological progress in radiology be transferred to the surgical area. The mobile C-arm image amplifier with television fluoroscopy and single-image storage device should be considered for orthopedic surgery and ER rooms. More sophisticated equipment is required for operative cholangiography and operative angiography.

Superior laryngeal nerve paralysis an often overlooked entity.

The anatomy and physiology of the larynx are discussed. The larynx is a dynamic structure, and motion pictures are helping to document and to clarify its dynamic behavior in the presence of diseases such as paresis and paralysis. The recognizable distinguishing features of unilateral and bilateral superior nerve paralysis are discussed in detail. These lesions often have gone unrecognized in the past and the patients mistakenly have been referred to the speech therapist with an incorrect diagnosis of "functional voice disorder."

Laryngeal involvement by systemic lupus erythematosus.

Indirect laryngeal photography with the rod laryngeal telescope provided an excellent method of documenting evolution of the laryngeal pathology in two cases of systemic lupus erythematosus. This disease may have mucosal or serosal manifestations in the larynx. Currently, management of mucosal disease includes acute and long-term corticosteroid therapy, and should the airway become compromised by edema or scarring, then tracheostomy and specific laryngeal reconstruction during a quiescent period in the disease is required. The course of serosal involvement, notably cricoarytenoid arthritis, may be followed by observing vocal cord motion sequentially and assessing the degree of throat pain. Oral corticosteroids in maintenance dosages is the accepted modality of treatment, with dosage being boosted for exacerbations.
