Introduction: Although the incidence and prevalence of chronic suppurative otitis media (CSOM) has been decreased in recent decades, but it is still a major health problem in both developing and developed countries. CSOM can cause major and life-threatening complications such as hearing loss, meningitis and cerebral abscess. Since hearing loss is the most common complication of CSOM, we aimed t...

INTRODUCTION Cholesteatoma is traditionally diagnosed by otoscopic examination and treated by surgery. The necessity for imaging in an uncomplicated case is controversial. This study was planned to investigate the usefulness of a preoperative high-resolution computed tomography (HRCT) scan in depicting the status of middle ear structures in the presence of cholesteatoma and also to compare the ...

Introduction  Chronic otitis media can cause multiple middle ear pathogeneses. The surgeon should be aware of relation between ossicular chain erosion and other destructions because of the possibility of complications. Objective  This study aimed to investigate the rates of ossicular erosion in cases of patients with and without facial nerve canal destruction, who had undergone mastoidectomy du...

In conductive hearing loss caused by otosclerosis stapes, surgery is the generally accepted treatment of choice. Since the introduction of stapes surgery in the 1950’s many different approaches have been developed. All modern procedures aim at reconstruction of a functional, mobile ossicular chain and adequate sound transfer at the stapes footplate. In the last two decennia small fenestra stape...

PURPOSE Initial study of the pig`s temporal bone anatomy in order to enable a new experimental model in ear surgery. METHODS Dissection of five temporal bones of Sus scrofa pigs obtained from UNIFESP - Surgical Skills Laboratory, removed with hole saw to avoid any injury and stored in formaldehyde 10% for better conservation. The microdissection in all five temporal bone had the following ste...

OBJECTIVE To analyze the results obtained from hydroxyapatite bone cement repair of ossicular discontinuity between the incus and stapes during surgery of retraction pockets. DESIGN Clinical study of a case series. SETTING Otolaryngology Department, Tanta University Hospitals, Tanta, Egypt. PATIENTS A total of 62 previously untreated patients (82 ears) with retraction pockets. INTERVENT...

Materials used in ossicular replacement prostheses must possess appropriate biological properties, such as biocompatibility, stability, no cytotoxicity. Due to the risk of infection (otitis media and chronic otitis media), it is desirable to use an antibacterial agent for illness prevention during the ossicular reconstruction. The goal of this work was to observe biological properties of a new ...

The use of genetically modified mice can accelerate progress in auditory research. However, the fundamental profile of mouse hearing has not been thoroughly documented. In the current study, we explored mouse middle ear transmission by measuring sound-evoked vibrations at several key points along the ossicular chain using a laser-Doppler vibrometer. Observations were made through an opening in ...

OBJECTIVE To explore the association between chronic suppurative otitis media and sensorineural hearing loss. METHOD The files of 147 patients with unilateral chronic suppurative media were reviewed in a retrospective study. Differences between diseased and control ear bone conduction thresholds were analysed by the paired student's t-test over the four frequencies (0.5 kHz, 1.0 kHz, 2.0 kHz,...
