the making of ear mould for hearing aids is generally considered to be a safe process. however, there are a few reported cases of complications caused during mould making. we report the case of a man with 69 years age, where the process of making the mould for a hearing aid led to the perforation of the tympanic membrane and pouring of mould material into the middle ear, necessitating surgical ...

background: with respect to physical relations in force and pressure, we hypothesized that the prevalence of traumatic tympanic membrane perforation in patients with a patulous eustachian tube is greater than normal, because in eustachian tube patency, the internal air pressure of the middle ear will not increase after compression, subsequent to trauma. therefore the force upon the tympanic mem...

introduction: tympanoplasty is a standard procedure to repair tympanic membrane perforation. the aim of this study is to evaluate the results of tympanoplasty (hearing improvement and tympanic membrane closure rate) in patients suffering from chronic perforation of the tympanic membrane by considering the prognostic factors.  materials and methods: in a prospective study, based on the results o...

introduction: tympanoplasty is the standard and well established procedure for closure of tympanic membrane perforations .this paper compares the results of tympanoplasty in terms of hearing improvement and graft incorporation in patients with chronic perforation of the tympanic membrane between two groups with and without active drainage at the time of surgery.  materials and methods: sixty re...

UNLABELLED The most common etiologies of tympanic membrane perforation are infections and trauma. OBJECTIVE The objective of the present study was to assess the healing of traumatic tympanic membrane perforation in rats. METHODS The tympanic membrane from male Wistar rats was perforated in the anterior and posterior portions to the handle of the malleus. Five tympanic membranes were evaluat...

background: assisted reproductive techniques (art) are used with increasing frequency worldwide. the present research was conducted to determine the effects of art on hearing defects and ear abnormalities. materials and methods: n a descriptive, cross-sectional, non-randomized study, the status of hearing and ear abnormalities was assessed in 300 newborns conceived by art at royan institute, te...
