AbstractSixteen patients with sudden deafness (SD), diagnosed on the basis of a battery of audiometric tests, but with no other medical or surgical pathology requiring drug treatment, underwent monitoring of their hemorheological profiles to see whether disturbances in the microcirculation could be linked to SD. Plasma viscosity, the filterabilities, (using a low‐shear positive pressure system) through 5‐μm‐diam‐eter pore Nuclepore filters, of whole blood and red and unfractionated white cells were monitored in 16 SD patients and 32 controls matched for age, sex and socioeconomic status. Whole blood filterability and the filterability of the red blood cells were significantly impaired in the SD patients, which suggests that alterations in the microcirculation are linked, in some way, to sudden

摘要:

AbstractThe electromyographic and contractile properties of the laryngeal muscles upon stimulation of the laryngeal nerve have been described before. In the present investigation, we used electrical and magnetic stimulation to activate the vocalis muscle in dogs. Stimulation of the vagus nerve at the brain stem exit point resulted in evoked vocalis compound muscle action potential identical in onset latency and configuration to that obtained by the transcranial single‐shock magnetic stimulation at high intensity (>80%). Electrical stimulation of the laryngeal representation of the somatomotor cortex resulted in a contra‐lateral evoked vocalis compound muscle action potential. Central delay time for the 10th cranial nerve was calculated by subtracting the latency of the vocalis recorded by stimulation of the vagus nerve as it exited the brain stem from the latency obtained by direct cortical stimulat

摘要:

AbstractPercutaneous nerve excitability testing using the Hilger facial nerve stimulator was introduced about 25 years ago. The test is reliable, easy to use, and inexpensive; it continues to be the most frequently used method for predicting prognosis of facial nerve disorders. Between 1966 and 1974, we recorded 10,243 nerve excitability tests on 865 patients with a mean of 3.29 tests for each peripheral branch and 3.43 for the trunk. Using a multiple regression model, we determined the effect on nerve stimulation values of age, sex, race, diabetes, hypertension, partial or complete clinical paralysis, diagnosis of herpes zoster, year of testing, and eventual facial paralysis recovery profile. We discuss statistical reliability, provide a table of interpretive results, and offer “tips and traps” invaluable to the practitioner. A prospective study of 25 patients with residual facial paralysis was evaluated by two separate otolaryngologists to determine intertester reliabil

摘要:

AbstractJet irrigation is an accepted method for removal of cerumen from the external auditory canal. Even at a submaximal power setting, oral jet irrigators can generate enough force to rupture the tympanic membrane. Parameters for safe use of these irrigators have never been established.Three cases are reported in which, in addition to tympanic membrane rupture, oral jet irrigators caused ossicular disruption, round and oval window fistulae, and subluxation of the stapedial footplate. A prospective study performed on 25 fresh cadavers demonstrated a 6% incidence of tympanic membrane perforation when the power setting was one‐third full power or greater. Recommendations are made for safe use of oral jet irrigators for removal of external auditory canal cerume

摘要:

AbstractNasal inverted papilloma is a rare benign tumor occasionally associated with squamous cell carcinoma. To determine the etiological role of human papillomavirus in inverted papilloma, and to clarify the relationship between human papillomavirus and malignant transformation of this benign tumor, we retrospectively analyzed inverted papillomas from 26 patients, 7 of whom had squamous cell carcinoma.We used an immunohistochemical method and molecular pathologic techniques, or dot‐blot hybridization of DNA extracted from paraffin‐embedded tissues, in situ hybridization, and polymerase chain reaction. Human papillomavirus was detected in 5 of 26 patients (19%), 3 patients with human papillomavirus 11 and 2 patients with human papillomavirus 16. The latter 2 patients had inverted papillomas associated with squamous cell carcinoma. We speculate that human papillomavirus may be related to the malignant transformation of inverted papillo

摘要:

AbstractParotidectomy may be associated with a significant depression in the retromandibular region and a significant incidence of gustatory sweating (Frey's syndrome). Superiorly and inferiorly based sternocleidomastoid flaps and posterior plication of the superficial musculoaponeurotic system were evaluated for their ability to ameliorate both consequences. Sixteen patients with sternocleidomastoid flaps and 16 patients with superficial musculoaponeurotic system plication were compared to a control group of 104 patients. The incidence of Frey's syndrome was 47.1% in the control group, 12.5% (P= 0.025) in the sternocleidomastoid flap group, and 0% (P= 0.005) in the superficial musculoaponeurotic system plication group. The surgical techniques are described. The prevalence of Frey's syndrome is discussed with respect to age, sex, radiation therapy, and the type of parotidectomy performed. The indications and contraindications of the three surgical techniques are described.
