Translabyrinthine Excision of a Transmodiolar Intralabyrinthine Schwannoma Mimicking Meniere's Disease: A Case Report.

Intralabyrinthine schwannomas (ILSs) are rare tumors involving the otic capsule. Notably, they are often misdiagnosed because their symptoms mimic those of other, more common inner ear pathologies. Diagnosis requires high-resolution contrast-enhanced magnetic resonance imaging (MRI), which reveals filling defects (using a T2-weighted MRI sequence) or focal enhancement (using a T1-weighted MRI sequence with gadolinium enhancement) in the inner ear.

An Unusual Finding During Exploratory Tympanotomy in a Case of Conductive Hearing Loss Mimicking Clinical Otosclerosis: A Case Series.

Conductive hearing loss with normal otoscopic findings has many differential diagnosis, but the diagnosis of otosclerosis is retrospective after exploratory tympanotomy. Congenital ossicular anomalies in isolation are rare and often have a delayed diagnosis, particularly if unilateral. Herein we present a rare case of stapes abnormality that was encountered as a surprise during exploratory tympanotomy in a case of conductive hearing loss mimicking clinical otosclerosis and was managed accordingly.

Use of three-dimensional printing for the osteoplastic flap approach: A viable technique.

The osteoplastic flap technique is the open and direct approach to the frontal sinus and is especially useful when disease extends laterally into the frontal sinus. One of the vital steps of surgery is delineation of the boundary of the frontal sinus. This can usually be performed either by using the classical 6-ft Caldwell view X-ray template or more recently by application of the image-guided navigation system.
