BACKGROUND
Vertigo during suction-cleaning of open mastoid cavities is caused by cold stimulation of the vestibular organ. In clinical and model-experimental measurements we tried to estimate the physical background and the dimension of this temperature drop.
METHODS
Using different techniques like
BACKGROUND
The diagnosis of perilymphatic fistula (PLF) is often difficult, and therefore the condition can be overlooked. Tympanoscopy presents an alternative procedure for visualising the middle ear anatomy, and it may help to diagnose PLF.
OBJECTIVE
The aim of this study was to evaluate the use
The association of vertigo and diseases of the middle ear is not uncommon. It occurs especially during the course of chronic or acute otitis but can also occur as a sequela. Vestibular involvement is due to several pathophysiological mechanisms that influence the choice of treatment. The same is
Suction toilet of mastoid cavities leads to unpleasant vertigo in many patients. We have shown that suction causes cooling within the cavity, in a series of 20 patients. This is of the same order of magnitude as a cold air caloric, showing the temperature drop to be an important factor. The relevant
By means of special probes, air temperatures were determined in external auditory meatus and in "radical" mastoid cavities. Under normal conditions, there was no difference between the two groups, the temperature next to the drum head being in the same range as the body temperature. Exposure to
The authors have found no studies and little guidance in the literature on the advisability of people swimming with a modified radical mastoid cavity. Two groups of such outpatients were therefore followed up at 2-monthly intervals for 6 months. One group of 56 patients swam (81% without ear
A case of severe vertigo, following multiple operations for chronic suppurative otitis media is described. Sensitive nystagmus-producing spots in the mastoid cavity were treated by cryosurgery. Despite the absence of histological evidence of sensory epithelium or nerve endings, a good result was
Vertigo induced by aural suction was abolished by maintaining a constant temperature in the mastoid cavity during the procedure. This was achieved using humidified air at 38 degrees C at the wider end of the aural speculum. The cavity temperature fell by a maximum of 0.2 degrees C (average) in 24
OBJECTIVE
To analyze characteristic of air caloric testing for patients with tympanic membrane perforation and to assess the availability of this testing for the patients.
METHODS
Forty-three cases of chronic otitis media with tympanic membrane perforation and vertigo were investigated, in which
Tinnitus is an otological symptom that is encountered often, yet its treatment is difficult. If tinnitus is of cochlear origin, a reasonable assumption is that a total depression of the cochlear function will abolish cochlear tinnitus. To achieve this depression, transtympanic infusion of a local
We have observed in our own practice that numerous patients with primary symptoms of vertigo exhibit cervical segmental muscular imbalance and increased tension in the masticatory musculature. This is frequently associated with functional blockades, especially in the joints of the head and upper
The open technique in cholesteatoma surgery has, besides a higher security concerning the recurrence of disease, some disadvantages: lifelong care for the cavity, often discharging granulations, and vestibular vertigo due to the lack of labyrinthine protection. Most of the disadvantages can be
BACKGROUND
Canal wall down tympanomastoidectomy is commonly used to treat advanced chronic otitis media or cholesteatoma. The advantages of canal wall down mastoidectomy are excellent exposure for disease eradication and postoperative control of residual disease; its disadvantages include the
OBJECTIVE
To examine the efficacy and safety of mastoid cavity obliteration using highly purified beta-tricalcium phosphate (beta-TCP) after mastoidectomy in middle ear surgery.
METHODS
Thirteen patients with cholesteatoma invading the mastoid cavity or showing severe pathologic changes in the
Otitis media chronica cholesteatomatica with cerebral sigmoid sinus thrombosis is an important differential diagnosis in the evaluation of headache. We describe a 31-year-old Filipino man with chief complaints of headache, otalgia, vomiting, and vertigo, and no significant past medical history. Two
