BACKGROUND Children undergoing magnetic resonance imaging (MRI) under sedation are at risk of hypo- or hyperthermia. The effect of brain MRI at differing magnetic field strengths on body core temperature in sedated infants and young children has not been reported previously. METHODS Two groups of 38 infants and children (aged 1 month to 6 yr 5 months) underwent brain MRI for different indicat...

OBJECTIVE To describe a relatively unknown clinical entity - inflammatory cast of the tympanic membrane after acute otitis media - and its simple out-patient treatment. STUDY DESIGN Retrospective review of case series. SETTING Subspecialty practice at a tertiary hospital. PATIENTS Seven patients diagnosed previously with acute otitis media with perforation or otitis externa, and with pers...

Vibration of tympanic membranes of the middle ear model with TORP and flat membrane made of gum were studied by means of holographic interferometry. Results were as follows. 1) As the tension of the gum became high, the amplitude decreased in low frequency. The segmental vibration was observed in low frequency as the tension became low. 2) The difference between 0.03mm and 0.06mm was not signif...

In terrestrial mammals, hearing starts with the perception of acoustic pressure by the tympanic membrane. Vibrations in this membrane are then transduced into the inner ear by the ossicle chain of the middle ear, composed of the malleus, incus and stapes. The proper connection of the ossicle chain with the tympanic membrane, provided by the insertion of the manubrium of the malleus into the ear...

Objective. The aim of this study is to evaluate the results of inlay butterfly tympanoplasty technique in large central tympanic membrane perforations. Methods. The files of the patients who underwent inlay butterfly cartilage tympanoplasty for large central tympanic membrane perforations were reviewed. Patients were followed with otoscopy and audiometry. Preoperative and postoperative pure-ton...

OBJECTIVES To examine the favorable effects of vitamin E on tympanic membrane perforations induced mechanically in guinea pigs. STUDY DESIGN Bilateral tympanic membrane perforations of 1.8 mm were induced in 40 guinea pigs. The animals were randomly divided into two groups equal in number. One group remained untreated, while the other was administered vitamin E (100 mg/kg/day) through intramu...
