“…In our study, these rates were 7 and 7%, respectively. Like Jang et al [ 10 ], Meyer et al [ 18 ] and Sone et al [ 19 ], we found no correlation between fistula size and postoperative BCT. Ikeda et al [ 20 ] did find a correlation between fistula size and poorer postoperative BCT.…”

The objective of the study was to evaluate postoperative hearing and disease control after cholesteatoma surgery for labyrinthine fistulas. In a retrospective cohort study, we evaluated a consecutive cohort comprising 44 patients (45 ears) with labyrinthine fistulas associated with chronic otitis media with cholesteatoma who underwent surgery between 2002 and 2015. We looked at patient characteristics, pre- and postoperative bone conduction thresholds (BCT), operative approach and findings, extent of disease and the occurrence of residual disease. All deaf ears (24%) presented preoperatively with a large fistula. Opening the membranous labyrinth resulted in significantly worse postoperative BCT (p = 0.01). Neither the present study nor a literature search revealed a significant positive effect of corticosteroids on postoperative hearing preservation. Large fistulas were correlated with poorer preoperative BCTs, but not with poorer postoperative BCTs. Opening the membranous labyrinth during surgery is correlated with poorer postoperative BCTs and can be seen as a predictive parameter. The use of corticosteroids in the perioperative management of labyrinthine fistula was not found to result in any improvement in postoperative BCTs.

“…Another complication related to cholesteatomas is the erosion of the semicircular canals, mostly the lateral canal, as it is placed nearer to the antroattical region where most cholesteatomas arise. CT-scans are able to predict these labyrinthine fistulas with a sensitivity of > 80% [5]. Several inner ear malformations, such as Michel's aplasia, common cavity deformity, cochlear aplasia or hypoplasia, semicircular canal aplasia or dysplasia, enlarged vestibular aqueduct, and Mondini dyplasia have been described.…”

Eight Items to Check on a Temporal Bone CT-Scan

Imaging data provided by computed tomography scans of the temporal bone are fundamental for both the diagnosis and treatment of diseases affecting this complex structure. Despite its importance, the expertise required to analyze this exam is seldom properly acquired as it is time-consuming and often neglected among young doctors and even otolaryngologists. Physicians may not even have a look at the scans but rely only on radiology reports. Radiologists, on the other hand, may not describe the individual scans the same way as clinicians. Lack of a standardized and didactic protocol for scrolling through the images obtained might also contribute to the difficulties reported by residents and physicians in daily practice. We present here a sequential checklist which could be employed in a systematic and organized manner, aiming to both develop and practice the know-how of this indispensable and challenging method of evaluation of the temporal bone.

Diagnostic Bedside Vestibuloocular Reflex Evaluation in the Setting of a False Negative Fistula Test in Cholesteatoma of the Middle Ear

Background. False negative fistula testing in patients with chronic suppurative otitis media is a dilemma when proceeding to surgery. It is imperative to rule out a dead labyrinth or a mass effect secondary to the cholesteatoma in an otherwise normally functioning inner ear. We present a case series of three patients in whom a bedside vestibuloocular reflex (VOR) evaluation using a head impulse test was used successfully for further evaluation prior to surgery. Results. In all three cases with a false negative fistula test we were able to further evaluate at the bedside and were not only able to register the abnormal VOR but also localize its deterioration to a particular semicircular canal eroded by the fistula. Conclusion. Vestibuloocular reflex evaluation is mandatory in patients with suspected labyrinthine fistula due to cholesteatoma of the middle ear before proceeding to surgery. We demonstrate successful use of a bedside head impulse test for further evaluation prior to surgery in patients with false negative fistula test.
