The intrinsic muscles of the larynx were exposed in each of 54 normal larynges derived from the autopsy series of a general hospital and submitted to microscopic examination. Muscle fibre alterations were found in all the posterior cricocarytenoid muscles in patients from 13 years of age on wards. In about half of the patients these changes included(More)

Gairn's method for nerve endings was used to study the mucous membrane of the nasopharynx. A simple type of end bulb was found in the fossa of Rosenmüller. The end bulbs were especially abundant near the tubal orifice. They are probably part of a pressure sensor mechanism having a direct reflex control on Eustachian tube musculature for the equalisation of(More)
In five patients with multiple system atrophy, electromyographic studies using a new surface electrode technique, showed unequivocal evidence of denervation of the posterior crico-arytenoid muscle, and in three of them, of the interarytenoid muscle or crico-pharyngeal sphincter. By comparison, only minor electromyographic abnormalities were found in(More)
A case of acute orbital cellulitis in an adolescent girl is reported and compared with ten cases treated in the same hospital in recent years. The clinical features and stages of orbital cellulitis and its differentiation from cavernous sinus thrombophlebitis is discussed. Although these complications are nowadays rare with modern chemotherapy and(More)
A new method of surface electromyography (EMG) is presented, for sampling the posterior crico-arytenoid, interarytenoid and crico-pharyngeal sphincter. The results obtained in normal volunteers are discussed and the indications for laryngeal electromyography (LEMG) outlined. It has the advantage of being non-invasive and safe, and can be done as an(More)
A case of congenital labyrintho-tympanic fistula is reported. The possible anatomical pathways and main clinical characteristics are discussed together with a review of the literature. Special emphasis is made for early recognition in children, of this entity without invasive forms of investigation, and the proper surgical approach via tympanotomy is(More)
A new method of surface 'integrated' electromyography is described for use in ENT practice. It is particularly suitable for the relatively delicate muscles of the mouth and throat. A special bipolar surface electrode has been designed to sample the interarytenoid, posterior crico-arytenoid and crico-pharyngeal sphincter. Very important EMG abnormalities(More)
1. A surface electrode was used to record electromyographic activity of the posterior cricoarytenoid muscle during breathing in normal subjects and patients with airflow obstruction. 2. Phasic activity of the posterior cricoarytenoid muscle was demonstrated. This was present on inspiration and absent on expiration. 3. Phasic inspiratory activity in normal(More)
