Nineteen cases of ossicular chain separation and ossicular dislocation due to head injury were presented. These cases were operated at an early stage after the trauma. The malleus was almost always involved in ossicular chain injury, while the incus was involved in 42% of our cases. The stapes was involved in 21%. The incudo-mallear joint is always separated while the incudo-stapedial joint is ...

BACKGROUND Middle ear surgery techniques can improve hearing destroyed by disease, but results of treatment are difficult to predict. Therefore, researchers use a Laser Doppler Vibrometer to measure vibrations of human middle ear ossicles. MATERIAL/METHODS Measurements of ossicular chain vibrations are performed on fresh human temporal bone specimens using Laser Doppler Vibrometer. Vibrations...

OBJECTIVE Since 1993, titanium prostheses have been used in Europe as a biocompatible implant for ossicular reconstruction. More recently, the titanium ossicular prosthesis has become more widely available in the United States as a newer means of surgical restoration of hearing. We will review the hearing results of patients who have undergone tympano-ossiculoplasty using a titanium total ossic...

HYPOTHESIS The osseointegrative capacity of medical-grade bone cement can be used to improve fixation and prevent displacement of an ossicular prosthesis in a guinea pig model. BACKGROUND Successful ossiculoplasty requires a firm connection between the vibrating tympanic membrane and the inner ear. In patients requiring revision ossiculoplasty, half of failures are due to prosthesis displacem...

OBJECTIVE The purpose of this study was to investigate etiological, clinical, and pathological characteristics of traumatic injuries of the middle ear ossicular chain and to evaluate hearing outcome after surgery. MATERIAL AND METHODS Thirty consecutive patients (31 ears) with traumatic ossicular injuries operated on between 2004 and 2015 in two tertiary referral otologic centers were retrosp...

BACKGROUND The principal objective of ossiculoplasty is to reconstruct the sound-conducting system in the ear to the best possible degree after the elimination of pathological lesions from the middle ear. The ossicular chain is reconstructed with the use of the patient's own properly modelled ossicles and synthetic prostheses. The objective of the study was to assess the degree of hearing impro...

OBJECTIVES This study was aimed to assess the relationship between the type of temporal bone area involved and conductive hearing loss. METHODS We enrolled 97 patients who visited the otolaryngology clinics of Seoul National University Hospital or Boramae Medical Center, Seoul Metropolitan Government-Seoul National University with temporal bone fracture between January 2004 and January 2014. ...

This study was conducted to find out the frequency of ossicular chain pathology in cases of tubotympanic chronic suppurative otitis media. This was prospective study, carried out in the department of otorhinolarymgology, NIMS medical college, Jaipur from Jan 2014 to June 2015. One hundred fifty cases of chronic suppurative otitis media, who underwent surgery, were included and their intraoperat...

OBJECTIVES 1. To investigate whether systematic preservation of the intact ossicular chain in cholesteatoma surgery provides better hearing than dismantling the chain and reconstructing it. 2. To determine whether systematic preservation of the ossicular chain in cholesteatoma surgery can be performed safely. STUDY DESIGN Longitudinal parallel group study. SETTING District general hospital ...
