Recurrent vestibulopathy.

Recurrent vestibulopathy is defined as an illness of unknown cause characterized by more than a single episode of vertigo of duration characteristic of that occurring with hydrops but without auditory or clinical neurological symptoms or signs. Eighty-six patients with this condition were diagnosed in the Dizziness Unit, and data on age and sex distribution, natural history and caloric pattern are presented. On follow-up of mean duration 3.5 year, 6 cases evolved to classic Ménière's disease, and 4 to benign positional vertigo, but none developed brain disease. The prognosis regarding vertigo is generally good. We consider the term recurrent vestibulopathy a logical designation of a distinctive clinical disorder with unknown cause but with probable peripheral vestibular origin, and hope that its use would spur research into previously unrecognized causes of recurrent vertigo.

Surgical treatment of vertigo.

Endolymphatic saccotomy, vestibular neurectomy via middle fossa, labrinthectomy and translabyrinthine vestibular neurectomy have been used by the authors in 54 patients with episodic vertigo, chiefly from Ménière's disease. Over a mean follow-up period of 15 months hearing retention and vertigo control were of the same general order as in the reports of other surgeons. Our current ideas on indications for the different surgical procedures are discussed.

Delayed endolymphatic hydrops.

Eighteen patients with delayed endolymphatic hydrops are presented. This distinctive entity typically affects young adults and is characterized by episodic vertigo of Ménière's type occurring years after a sudden hearing loss. Measles or mumps were thought to have caused the hearing loss in eight patients. In the entire group of 18 patients the delay between identification of hearing loss and vertigo averaged 22.6 years. The diagnosis is aided by electronystagmography and labyrinthotomy in selected cases. Medical treatment may be effective and surgical treatment is curative.

Arnold-Chiari malformation--some otoneurological features.

Arnold-Chiari malformation was diagnosed in five patients with vertigo. Four were of anatomical type I. A case report is given of one patient who presented features of a unilateral cerebellopontine angle lesion. Downward beating vertical nystagmus was an important finding in three of the five patients. Other clinical and radiological features of the condition are discussed.

Blood glucose and insulin levels, thyroid function, and serology in Ménière's disease, recurrent vestibulopathy, and psychogenic vertigo.

Nineteen patients with unilateral Ménière's disease, 20 with psychogenic dizziness, and 20 with recurrent vestibulopathy (diagnostic criteria in text of paper) were found to have normal five hour glucose tolerance tests, serum thyroxine and effective thyroid indices, and serologic tests for syphilis. Hypothyroidism and hypoglycemia were absent in all groups. An unexplained finding of each diagnostic group was significant increase of fasting blood glucose and insulin levels, and elevated insulin:glucose ratios, compared to a control group. There appears to be no diagnostic indication for performing these chemical and serologic studies in patients with unilateral Ménière's disease, psychogenic vertigo, or recurrent vestibulopathy. Reasons are given to support the view that recurrent vestibulopathy may be a specific vestibular disturbance.

Air caloric stimulation with tympanic membrane perforation.

Warm air caloric stimulation in an ear with tympanic membrane perforation or mastoidectomy cavity often causes contralateral nystagmus. Secondary nystagmus is common. Our evidence with squirrel monkeys and patients indicates that the primary "inversion" results from endolymph cooling due to evaporative cooling due to evaporative cooling of the mucus lining the middle ear cavity, by the dry air stimulus. Disconjugate horizontal nystagmus was found in a patient with large eardrum perforation, after cold air caloric stimulation. The effect probably resulted from stimulation of the anterior or posterior vertical semicircular canal. Inverted or disconjugate caloric nystagmus after air stimulation is much more frequently due to tympanic membrane perforation, or moisture in the external ear, than to central nervous system disease.

Bilateral paroxysmal positioning nystagmus.

The term "bilateral paroxysmal positioning nystagmus" (BPPN) refers to the occurrence of paroxysmal positioning nystagmus when the patient's head is placed in both right and left head-hanging positions. BPPN was found in at least 15% of 114 patients with benign positional vertigo. Head injury, central nervous system disease or both were causative in over half of patients with the finding. In some instances, paroxysmal positional nystagmus may be found when the abnormal ear (side) is uppermost rather than directed toward the floor; this fact may have important implications if singular neurectomy is to be performed.

Computer processing of audiological and vestibular data. II. A further note.

This paper provides an addendum to an earlier paper describing the development of a computer record system for patient data. The specific problems addressed pertain to the storage and retrieval of historical information, physical signs and diagnosis. Some preliminary comparisons of audiological and vestibular test results are given for groups of patients with diagnoses of acoustic neuroma, Ménière's disease, temporal bone fracture and vestibular neuronitis.

A study of acupuncture in adult sensorineural hearing loss.

Twenty-nine adult volunteers with stable bilateral sensorineural hearing loss were treated by acupuncture. Subjects were randomly assigned to one of four experimental groups: active needling, active needling followed by sham needling, sham needling followed by active needling, and sham needling. All subjects received 30 treatments. Only one ear was treated by acupuncture. The second ear was kept for an intrasubject control. Prior to treatment a baseline of hearing was established. During the course of acupuncture, audiological assessments (pure tone thresholds and speech tests) were made after sets of five treatments. Hearing was again measured during the year following acupuncture. The results in individual subjects and statistical comparisons of active and sham groups showed that acupuncture did not produce significant shifts in hearing.

Round window fistula.

Round window fistula as a cause of sudden hearing loss was diagnosed in five people. It was associated with a sudden change in middle ear pressure in three, with heavy lifing in one, and was probably caused by a significant blast exposure in the other. The clinical features of the condition are varied, with hearing loss and tinnitus being the only constant findings in our patients. One case demonstrates, perhaps for the first time, the association of an abnormally mobile portion of the round window membrane with vertigo and nystagmus. Suggestions on identification and management of round window fistula are made.
