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...

Techniques and biomaterials for reconstructive middle ear surgery are continuously and steadily developing. At the same time, clinical post-surgery results are evaluated to determine success or failure of the therapy. Routine quality assessment and assurance is of growing importance in the medical field, and therefore also in middle ear surgery. The exact definition and acquisition of outcome p...

The study of the dynamics of the human tympanic membrane is important for better understanding of the hearing mechanism of the normal and reconstructed middle ear. A middle ear implant, for instance, needs to have the same transmission properties as a normal human middle ear. The transmission properties are determined by evaluating the transfer function of the middle ear, which is determined by...

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...

The surgical results of ossicular chain reconstruction using a hydroxyapatite prosthesis were evaluated in 106 ears of 101 patients who were followed up for > 5 years. Successful reconstruction was defined as: (1) postoperative air-bone gap of </= 20 db; or (2) postoperative air conduction better than 40 db; or (3) hearing gain better than 15 db. Success in hearing was obtained in 63/106 ears (...
