AbstractDrooling involves great practical problems in the care of patients with cerebral paralysis and mental deficiency. Different types of medical and surgical treatments have been used. In 17 disabled patients chorda tympani has been cut bilaterally in order to reduce the production of saliva, especially from the submandibular and sublingual glands. The loss of taste on the anterior part of the tongue seems to contribute to the reduction of salivation. Fifteen patients have been observed postoperatively during two to four years. Five patients have been cured, two are considerably improved and seven partially improved. The effect of nerve section was illustrated by Tcm99 scintigraphy in two additional cases before operation and six months postoperatively. No complications were observed.

摘要:

AbstractA retrospective study of 11 children with fibrosarcoma of the head and neck is presented. Six of these tumors are well differentiated, and three are poorly differentiated. Nine patients were followed for over six years and are available for treatment evaluation. The results of treatment indicate that patients with superficially located, well differentiated tumors occurring at sites where wide surgical margins can be obtained have the most favorable prognosis.

摘要:

AbstractA case of bilaterally symmetrical genetic aplasia conforming to Mondini type of congenital deformity in a 12‐day‐old child is presented with the help of temporal bone sections. Cochlear changes include a stunted modiolus, deficient interscalar septum between the middle and upper coils forming a scala communis cochleae, a degenerated organ of Corti and reduced spiral ganglion cells and dendrites. The vestibule is malformed, with membranous labyrinth being deficient. The utricle and semicircular canals are absent. There is no oval window or stapedial footplate, and the facial nerve is hypoplastic. An interesting feature is the unusual association of bilateral bony choanal atresia, atrial septal defect, cleft lip, absence of olfactory bulbs in the brain, and congenital ophthalmic anomal

摘要:

AbstractAn inexpensive and practical method for delivering air into the aural canal at a selected stable temperature is described. A water‐air heat exchanger utilizing the external circulation of a constant‐temperature water bath brings the temperature of the air stream to a chosen value. Measurements indicate stable air outflow temperatures are maintained when proper nozzle design and air flow rates are employed. The apparatus is easy to construct and has proven convenient and effective when used in the clinical vestibular laborat

摘要:

AbstractThe ampullar endolymphatic potential (AEP) was studied in the guinea pig during ischemia and asphyxia and following systemic application of ethacrynic acid. In addition the specialized and nonspecialized portions of the ampullar wall were analyzed for ATP and P‐creatine at different conditions of metabolic interference. Under control conditions the AEP amounted to + 4.6 ± 1.2 mV. In both types of hypoxia the decline of the AEP proceeded on a much slower time scale than that of the cochlear endolymphatic potential (CEP), and the maximum negativity reached was considerably less. Quantitative analysis of both types of ampullar wall tissue indicated a much slower decline in hypoxia of ATP levels than in the stria vascularis. Changes in P‐creatine levels were considerably more rapid. The AEP became reduced and changed polarity also by intoxication with ethacrynic acid (EA), but higher dosages (above 70 mg/kg) were necessary than for effects upon the CEP and much longer time periods were required for attainment of maximum negativity. The maximum negativity of the AEP was significantly greater at a dosage of 100 mg/kg of EA than during ischemia. At the point of maximum depression of the AEP P‐creatine levels in both types of ampullar tissue were unchanged, but ATP levels were significantly reduced in the specialized portions of ampulla

摘要:

AbstractA modified instrument for crimping the stapes prosthesis is described. This instrument allows direct visualization of the prosthesis during the crimping maneuver lessening the possibility of damage to the incus or to the wire prosthesis.
