Objective: To investigate the temporal bone with a malformed stapes in VACTERLS association.
Study Design: The study design was a case report, histopathology of the temporal bone, and three-dimensional reconstruction of the ossicles and cochlea.
Setting: The study was carried out in the Temporal Bone Bank at Charles University, Hradec Králové, on a case from Temporal Bone Foundation, Boston.
Patient: A 1540-g, 41-cm female neonate with VACTERLS association, histopathology of the temporal bone, and three-dimensional reconstruction of the middle ear ossicles and cochlea.
Results: The posterior part of the footplate was missing, and the posterior crura of the stapes was not connected to the footplate but found freely suspended in the sinus tympani.
Conclusion: Computer-assisted three-dimensional reconstruction was performed from histologic sections of the temporal bone removed from a case of VACTERLS association. The reconstruction included structures such as the bony labyrinth and the middle ear ossicles. The abnormality observed in the reconstruction included the mislocation of the stapes and a shortened footplate.

In otolaryngology, training often involves simulation in animal specimens, human cadavers, and artificial models to facilitate learning surgical procedures, reducing the time needed to acquire essential skills. Simulated training has become integral to medical education, particularly in microsurgical techniques, such as microlaryngeal surgery. These procedures, also known as phonomicrosurgery, are performed on the vocal folds using microscopic visualization and precision instruments with long shafts and millimetric tips.

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: Segmentation of the cochlea in temporal bone computed tomography (CT) is the basis for image-guided otologic surgery. Manual segmentation is time-consuming and laborious.
Purpose: To assess the utility of deep learning analysis in automatic segmentation of the cochleae in temporal bone CT to differentiate abnormal images from normal images.

Objective: This study aims to analyze anatomical parameters of the transmission route of sigmoid sinus tinnitus (SST) to explore its mechanism and speculate on possible responsible anatomical abnormalities.
Methods: Clinical data were retrospectively collected from SST and sigmoid sinus wall dehiscence (SSWD) patients suggested by temporal bone high resolution computed tomography (HRCT), with and without tinnitus, at the First Affiliated Hospital of Chongqing Medical University from January 2015 to August 2022. Patients were divided into SSWD tinnitus ( = 61), and non-tinnitus ( = 60) groups based on HRCT features.

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.
