Objectives: In tympanoplasty operations if perforation is related with malleus handle, malleus handle is desepithelised. We planned this research to investigate whether the epithelial remnants remain as a result of this desepithelisation or not.
Methods: The 35 patients who were performed tympanoplasty operation were divided into two groups. In the first group which included 13 patients the tip portion of manubrium mallei were cut off without desepithelisation. In the second group which included 22 patients the tip portions of manubrium mallei were cut off after the meticulous desepithelisation. The presence of squamous epithelium was examined histopathologically on the specimens.
Results: Squamous epithelium was observed in 9 of the 13 non-desepithelised specimens and in 6 of 22 desepithelised specimens.
Conclusion: In tympanoplasty operations despite careful desepithelisation, squamous epithelial remnants may remain on the malleus handle. So the tip of manubrium mallei could be resected to prevent the future development of cholesteatoma.

Background: The ossicula auditus is the structure that transmits vibrations from the tympanic cavity to the auris interna. This assembly is formed by three ossicles: the malleus, incus and stapes. In addition, the bone that exists as os lenticulare in humans exists as processus lenticulare in most mammals.

It is important to know the morphometry of the auditory ossicles for middle ear surgical applications. The present study aims to investigate the morphometric measurements of sheep auditory ossicles and the relationship between these ossicles. In this study, 100 malleus, incus and stapes of 50 Akkaraman sheep were examined using at trinocular stereo microscope and a total of 19 morphometric measurements were taken.

Objectives: Establish normal reference values for the human malleus during the second and third trimesters of pregnancy, and describe its growth dynamics and ossification process.
Methods: Thirty spontaneously aborted human fetuses, 12-36 weeks of age, were examined. Temporal bones were obtained en bloc and processed using the skeletal clearing and staining technique.

Background: The present study aimed to investigate the visibility of small ossicle parts/landmarks on high-resolution computed tomography (HRCT)/3D reconstruction (3D) to investigate what improvements in scanning resolution are needed before accurate 3D printing of patient-specific ossicles is possible.
Methods: A total of 24 patients with sudden deafness sought consultation at the Department of Otorhinolaryngology Head and Neck Surgery at the Sixth Medical Center of People's Liberation Army General Hospital between October 2013 and June 2014 were enrolled in the study. All participants underwent a 256-slice spiral HRCT temporal bone axial scan, yielding a Digital Imaging and Communications in Medicine documents series.
