Objective: To assess the high-resolution CT scan in depicting the middle ear structures.
Method: The surgical findings of 51 ears operated on were retrospectively compared with the CT findings. The followings were analysed: diagnostic features of chronic otitis media (COM) on CT status of the middle ear structures (ossicles, facial nerve canal, semicircular canals and tegmen tympani), and anatomical variations.
Result: The radio-surgical agreement was excellent for the malleus (kappa statistics, k = 0.840) and tegmen (0.788), good for the incus (0.700) and semicircular canals (0.56), but poor for the stapes (0.366) and facial nerve dehiscence (0.310). Potential surgical hazards detected by the scans included: Low lying dura, high jugular bulb, anterior lying sigmoid sinus, facial nerve dehiscence and other situations brought about by the destructive nature of the lesion.
Conclusion: There is a good radio-surgical correlation in COM for most middle ear structures except for the integrity of the facial canal and stapes. The scan alerts the surgeon the potential surgical dangers and complications of disease. High-resolution CT scan should be a routine examination prior to middle ear and mastoid surgery.

Introduction: Glomus tympanicum is a benign tumor classified under the group glomus tumors, and is also known as paragangliomas.
Case Presentation: A 52 years old woman presented with unilateral pulsatile tinnitus and hearing loss. She had a visible reddish mass behind the eardrum; Temporal bone CT scans suggested middle ear mass secondary to Glomus Tympanicum tumors.

Unlabelled: Increasing planting density is one of the most important strategies for generating higher maize yields. Moderate leaf rolling decreases mutual shading of leaves and increases the photosynthesis of the population and hence increases the tolerance for high-density planting. Few genes that control leaf rolling in maize have been identified, however, and their applicability for breeding programs remains unclear.

Objectives: Chronic otitis media (COM) is a prevalent condition affecting auditory function. Ossiculoplasty is a known treatment strategy, but its effectiveness concerning the presence of cholesteatoma has not been extensively studied.
Methods: We conducted a multicentre study involving 153 patients diagnosed with COM without cholesteatoma (ncCOM) and with cholesteatoma (cCOM).

Objectives: This research aims to validate the digits-in-noise (DIN) test for the Italian language and develop a version capable of independently assessing both ears while maintaining acceptable administration times.
Methods: Individual digits from 0 to 9 in Italian were recorded and adjusted to equalise recognition probabilities. An iOS application (APP) was developed for the independent ear test using triplets in noise.

Objective: This study aimed to assess the feasibility of the deep learning in generating T2 weighted (T2W) images from diffusion-weighted imaging b0 images.
Materials And Methods: This retrospective study included 53 patients who underwent head magnetic resonance imaging between September 1 and September 4, 2023. Each b0 image was matched with a corresponding T2-weighted image.
