The diagnosis of the ossicular condition, fixation or interruption, is often not achieved by the routine tympanometry. A new tympanometric system has been developed in order to improve the diagnostic value. This produces a sweep-frequency probe tone of 200 to 2000Hz and measures the sound pressure difference and the phase difference between the output and the input. An experimental study was pe...

Chronic suppurative otitis media, with or without cholesteatoma, may lead to erosion of the ossicles and discontinuity of the ossicular chain. In incomplete ossicular discontinuity (IOD), partial erosion of the ossicles occurs, but some sound transmission is noted throughout the ossicular chain. High-frequency conductive hearing loss (HfCHL) has been considered a hallmark of incomplete ossicula...

OBJECTIVES In this study, we aimed to evaluate the anatomical and functional results of open cavity tympanomastoidectomy due to chronic otitis media with cholesteatoma. PATIENTS AND METHODS Between January 2003 and October 2009, 166 patients who underwent open cavity tympanomastoidectomy due to chronic otitis media with cholesteatoma in our clinic were retrospectively analyzed. Seventy-two ea...

INTRODUCTION Temporal bone encephaloceles and cerebrospinal fluid (CSF) leaks are associated with an increased risk of life-threatening intracranial infection. Defects in the floor of the middle cranial fossa are attributed to prior infection, trauma, iatrogenic injury, and increased intracranial pressure. In the temporal bone, intracranial contents most commonly pass through dehiscences in the...

The standard treatment for acquired cholesteatoma involves surgical removal of the lesion and reconstruction of the tympanic membrane. In some children, these lesions can be treated more conservatively. We conducted a retrospective study of 29 ears in 24 children who had been treated for early acquired cholesteatoma with mechanical reduction and a tympanostomy tube. Outcomes measures included h...

OBJECTIVES We describe the histopathology of ossicular grafts and implants so as to provide insight into factors that may influence functional results after surgery for chronic otitis media. METHODS Histopathologic observations were made on 56 cases: 50 surgical specimens and 6 temporal bone cases in which the graft was sectioned in situ. RESULTS AND CONCLUSIONS Autogenous malleus, incus, a...

Objective Chronic otitis media most commonly causes an ossicular chain defect in incus. Different materials can be used for repair of this defect. In this study, the hydroxyapatite prosthesis, used for repair of the incus defect, was compared with the incus interposition. Methods Between 2010 and 2016, 27 female and 16 male patients who underwent ossiculoplasty due to an incus defect were stu...

We reported a rare case of ear trauma with delayed facial paralysis, ossicular chain dislocation and perilymph fistula caused by an earpick. A 36-year-old male consulted our clinic with a complaint of left otalgia, hearing loss, tinnitus and dizziness after left ear trauma with an earpick. Otoscopic examination showed perforation of the left ear-drum and pure tone audiometory demonstrated a mix...
