conclusions our study shows in terms of figures that measurements of features of the temporal bone made from spiral ct scan images and those directly obtained during surgery are similar to an adequate extent. results twenty cases were included. in the three measurements performed in this study, only the first parameter (distance between the canal and the sigmoid sinus) was significantly differe...

OBJECTIVES/HYPOTHESIS To evaluate the efficacy of image-guided surgical navigation (IGSN) in otologic surgery and establish practice guidelines. STUDY DESIGN Prospective study. METHODS Between January 2003 and January 2010, all patients requiring complicated surgery for chronic otitis media, glomus jugulare, atresia, cerebrospinal fluid leak with or without encephalocele, and cholesterol gr...

An instrument has been designed to combine a suction and an elevator for use in ear surgery.

Tonsillectomy is the most common surgery performed by an ENT surgeon & it is the most risky surgery as its complications are sometime life threatening. So far not much effort has been focused in training the junior residents in tonsillectomy using the models, like temporal bone dissection for ear surgeries, whereas lot of live ENT surgical workshop are conducted other than tonsillectomy to trai...

BACKGROUND There is a clear need for a prosthesis that improves postural stability in the balance impaired. Such a device would be used as a temporary aid during recovery from ablative inner-ear surgery, a postural monitor during rehabilitation (for example, hip surgery), and as a permanent prosthesis for those elderly prone to falls. METHOD OF APPROACH Recently developed, small instruments h...

Otological microsurgery is delicate and requires high dexterity in bad ergonomic conditions. To assist surgeons in these indications, a teleoperated system, called RobOtol, is developed. This robot enhances gesture accuracy and handiness and allows exploration of new procedures for middle ear surgery. To plan new procedures that exploit the capacities given by the robot, a surgical simulator is...

Hearing loss and tinnitus are the main symptoms of otosclerosis. Little is known about the cause of tinnitus in otosclerosis and the factors influencing the effect of surgery on tinnitus. Though by surgery, we are able to inform patient about probable hearing gain and even benefit concerning bilateral hearing, it is however difficult to predict the course of tinnitus. The principle aim of stape...

A case of Serratia marcescens meningitis in a 66-year-old man is reported. The infection occurred 4 weeks after apparently successful otic surgery, and a nidus of infection in the middle ear was established at autopsy. This is the second case of S. marcescens meningitis following ear surgery reported in the English-language literature.
