Cholesteatomas that occur under an intact tympanic membrane in the absence of prior surgical procedures or perforation are defined as congenital cholesteatomas. These entities are rarely seen, because they do not cause any major symptoms unless they touch the ossicular chain. Likewise, isolated congenital ossicular anomalies that occur independently of external ear anomalies and craniofacial dysplasia are also rarely seen. Here, we report a patient who presented with congenital cholesteatoma associated with anomalies of the ossicular chain and discuss its pathogenesis.

This study aimed to investigate the efficacy of inverted door flap (IDF) combined with transcanal approach to the tympanic antrum (TCAA) technique under the endoscope for treatment of middle ear cholesteatoma. Outcomes of patients treated with combined techniques at the First People's Hospital of Foshan City between March 2021 and March 2023 were evaluated. A total of 31 patients (33 ears, 16 males and 15 females) aged (42.

Temporal bone CT is an essential technique for diagnosing ossicular chain trauma, and the location of standard observation planes (SOP) is the foundation of imaging diagnosis. The ossicular chain is small in volume, and there are about 11 standard observation planes for ossicular chain diagnosis, so it is a professional and time-consuming task to label SOPs accurately. An automatic annotation method of SOP is proposed.

BACKGROUND The Carhart effect consists of a reduction in bone conduction thresholds associated with conductive hearing loss. The aim of this study was to evaluate the role of the Carhart effect in predicting outcomes from surgery in 3 age groups. MATERIAL AND METHODS This study included 532 patients with conductive hearing loss due to otosclerosis, otitis media with effusion, and chronic otitis media who underwent surgery between 2010 and 2020.

Introduction: The tympanic cavity contains three tiny bones, the malleus, incus, and stapes, which have a fundamental role in the transmission of sound. Recent research emphasizes the use of CBCT for the anatomic study of the temporal bone. The information about middle ear anatomy on CBCT scans is meager; hence, this retrospective study was conducted to identify and determine the various morphometrical parameters of the malleus using CBCT which can be helpful during reconstructive procedures for the otologic surgeon.

Objective: The primary aim of this study was to investigate the accuracy of a semi-automatic algorithm in assessing the feasibility and complexity of endoscopic stapes surgery preoperatively.
Methods: A semi-automatic algorithm was developed to simulate endoscopic stapes surgery in 3D. To test the accuracy of the algorithm, five fresh-frozen cadaveric heads (ten ears) were used.
