“…Bess et al (1), who described 3 such patients, stated that H. House and C. Shea had observed at least 90 similar patients in their clinical practices. Schuknecht (4) speculated that the incidence of such "otologic mysteries" may be 1 in 3,000 procedures.…”

“…Bess et al found pathologic third windows to be a potential cause of conductive hearing loss in 20% of patients who failed to obtain hearing gain after exploratory tympanotomy and ossiculoplasty. 13 Of the congenital middle ear abnormalities observed, congenital stapes agenesis was seen in 1 patient and it was first reported by Mcaskile et al in two patients who had conductive hearing loss. 14 Another middle ear abnormality encountered was a high jugular bulb which can be present in 10%-15% of individuals and can be dehiscent in 0.5%-1.7% which can also be the cause of hearing loss.…”

The diagnosis is suspected clinically based on microscopic otoscopy, audiometry, and tympanometry. Thin-section computed tomography of the temporal bone helps to confirm the diagnosis. This case report aimed to promote the importance of tympanometry screening as a diagnostic tool for middle ear pathology. A case of 27-year-old patient came to ENT-OPD at Al-Ameen Medical College and Hospital, Vijayapur with the complaint of decreased hearing since 2 years. The history of intermittant tinnitus and swimming habit with head bath regularly were found in the patient. Also, there were no significant family history of hearing loss, ear discharge, and ear pain. This case report concluded that the continuous head bath may leads to middle ear pathologies like otosclerosis and give importance to tympanometry test for early clinical diagnosis and suggesting for avoiding swimming, and also use of ear plugs as necessary during head bath.

“…This condition of incudal pseudocontinuity produced by the intact periosteum creates a surgical and radiological diagnostic trap [18]. In this situation (as in cases 3,6,8,10), one possible procedure to detect the obscure lesion is proposed in this study.…”

Virtual endoscopy (VE) is a recently developed technique to provide a realistic surface rendering of various organs, which can be applied to the use of three-dimensional (3D) studies of several lesions. However, its advantages in otological disease have not been well investigated. In this study, we evaluated the application of VE in patients with ossicular chain anomalies. Virtual middle ear endoscopy was a time-saving method, however, we needed the appropriate technical procedures of algorithm and reconstruction spacing to generate accurate 3D images of ossicles. We obtained virtual surgical views of middle ear structures and related anomalies, and confirmed by intraoperative findings that these images were mostly compatible with the actual lesions of ossicles. VE allowed an identification of the anatomy of the ossicles and adjacent structures simultaneously. The elements of the stapedial crura were clearly visualized with VE images in 93.3% of normal ears. Pathological ossicular chain findings such as malleus or incus fixation, dislocation and disruption, except footplate fixation were investigated successfully. One possible procedure, using alterable CT value in the obtained VE images on the monitor, is proposed for further detection of fine lesions of the ossicles. These observations suggest that virtual middle ear simulations accurately represent major intraoperative findings. This technique may have an important role in preoperative planning, surgical training, and/or postoperative evaluation in otology.
