摘要:

Four cases of tympanic membrane cholesteatoma are presented and the characteristics of this lesion are discussed. Failure to recognize and remove all the squamous epithelium medial to the tympanic membrane at the time of grafting eventually will result in graft breakdown due to continued production and desquamation of squamous epithelium into the middle ear.

摘要:

Defects of the dura mater, which are a source of cerebral spinal fluid leakage, may be produced by trauma and otologic and neurosurgical operations. Proplast was evaluated as a graft material to close dural defects in three animal models (cats). For comparison, temporalis fascia was similarly evaluated in an additional three cats. Microsurgical techniques were utilized to close the defects, and both materials successfully prevented cerebral spinal fluid leakage. Proplast, however, was judged superior when studied microscopically at three months. There was ingrowth of living dura into the Proplast and no evidence of inflammatory reaction.

摘要:

This article is based on a study of 178 patients with the diagnosis of temporomandibular joint (TMj) syndrome and a review of the literature, including diagnosis, symptoms, and treatment. Patients were treated by means of physical therapy, with relief of muscle and joint symptoms in 64 percent of the patients and a recurrence rate of 20 percent. Ear symptoms were relieved in 54 percent of the patients with a 32 percent recurrence rate. X-ray findings are also reviewed.

摘要:

The clinicopathologic findings in the temporal bone of a patient with a highly malignant metastasizing glomus jugulare tumor are reported. The patient exhibited all the symptoms of primary malignant tumors of the ear, including facial paralysis, otorrhea, pain, hearing loss, tinnitus, dizziness, and vertigo. He was treated with cobalt irradiation followed by radium implant in the ear canal for a residual tumor; then a left-sided radical mastoidectomy was performed.

摘要:

A protocol was designed to evaluate babies in neonatal intensive care units by means of the auditory brain stem response (ABR) audiometric technique during their hospitalization. This article presents the results obtained from 200 babies. Twenty-three infants failed the ABR test. Fifteen babies were followed. Ten of these infants had significant sensorineural hearing loss. Three had unilateral involvement and seven had bilateral impairment. The seven bilaterally affected infants were fitted with appropriate hearing aid amplification and enrolled in audiologic habilitation programs. Continued follow-up of these babies has confirmed the hearing loss diagnosis. These data estimate that 5 percent of babies in neonatal intensive care units have some degree of hearing loss. The findings encourage the use of the ABR technique as a means of identifying hearing loss in the neonatal intensive care unit population.

摘要:

Orofacial dyskinesia (Meige's syndrome) is a rare clinical entity. This disorder was first described in 1910 by Henry Meige as “spasm facial median,” a disabling spasm of the facial musculature which had frequently been misdiagnosed and inappropriately treated. This report concerns a patient who presented with tonic hemifacial spasm twenty-two years after contracting Bell's palsy. The condition was initially thought to be secondary to faulty regeneration of the facial nerve until Meige's syndrome became fully manifested over a period of two years. The diagnostic characteristics as well as the forms of treatment for this unusual disorder are presented.

摘要:

Extensive research into the inmost mechanism of otospongiotic disease and an extended study of otosclerotic patients' ancestry have led the authors to a plan for prevention of this disease, which appears to be a genetic deafness with autosomal dominant inheritance and about 40 percent penetrance of genes.Progress in impedance audiometry has permitted early detection of stapedial fixation by means of systematic audiometric investigations, particularly the elicitation of stapedius reflex showing a very special pattern called the “on-off effect,”The evidence supporting an enzymatic origin of the sensorineural component of hearing loss in otosclerotic families has led us to treat otospongiotic children with very low doses of sodium fluoride, with no risk of stunting growth.We have been applying this procedure for four years to the families of stapedectomized otosclerotic patients. We believe it would be advisable to extend this type of prevention to schoolchildren by means of systematic audiometric investigations, including the elicitation of stapedius reflex to detect a possible on-off effect.We also studied sodium fluoride therapy, which derives from the enzymatic origin of the otospongiotic disease. This treatment, based on enzymogenesis inhibitors, should be given to young otospongiotic/otosclerotic patients detected by systematic audiometric investigations. Sodium fluoride could even be prescribed for otospongiotic mothers to prevent disease in their newborn children, exactly as in dental prevention.Otospongiotic/otosclerotic disease can be easily controlled by medical treatment, combined with surgery if needed. This treatment is effective thanks to early detection.

摘要:

This is a review of the English literature relative to acoustic tumors from 1979 through 1982. I have selected what I consider the most important articles. Many other significant papers are not discussed.The material is presented in ten categories: diagnosis, histopathology, surgical approaches, facial nerve preservation and repair, von Recklinghausen's disease and bilateral tumors, nonacoustic cerebellopontine angle tumors, instrumentation, basic research, complications of surgery, and miscellaneous topics.In each section the articles are briefly reviewed, and sometimes a personal point of view is presented.

摘要:

This is a case report describing a large asymptomatic residual cholesteatoma in the middle fossa of a patient who had had a classic modified radical mastoidectomy twenty-six years previously.
