Objective: The purposes of this study were to determine the prevalence of abnormalities in the middle ear and mastoid cavity on the magnetic resonance imaging (MRI) in children and correlate the results with clinical data, tympanometric findings and paranasal sinus changes.
Materials And Methods: A total of 85 consecutive pediatric patients for suspected non-inflammatory intracranial pathologies were prospectively examined. MRI was conducted for the suspected intracranial pathology. All patients were also examined by an otolaryngologist for otologic pathologies. A tympanometry examination was performed in patients prior to MRI scan.
Results: In 23 (27.1%) of 85 (39 males, 46 females) children, MRI demonstrated middle ear and/or mastoid cavity abnormalities. MRI abnormalities of the middle ear and/or mastoid cavity were correlated with clinical data and tympanometric findings.
Conclusions: Incidental abnormal signal intensities in the middle ear and/or mastoid cavity are frequent in children, especially in first years of life. MRI will demonstrate incidental middle ear and mastoid cavity abnormalities seems to have clinical significance.

This study aimed to investigate the topological properties of brain functional networks in patients with tinnitus of varying durations. A total of 51 tinnitus patients (divided into recent-onset tinnitus (ROT) and persistent tinnitus (PT) groups) and 27 healthy controls (HC) were recruited. All participants underwent resting-state functional MRI and audiological assessments.

In recent years, transcanal endoscopic ear surgery (TEES) has gained widespread recognition as an excellent surgical field for blind spots such as the sinus tympani (ST) when compared to microscopic ear surgery (MES). To investigate the postoperative hearing results for pars tensa cholesteatoma and the indications for utilizing endoscopy. The medical records of 16 patients (10 men and 6 women) with pars tensa cholesteatoma, who received initial surgical treatment between 2018 and 2022, were reviewed.

Background: Recent advances in artificial intelligence have facilitated the automatic diagnosis of middle ear diseases using endoscopic tympanic membrane imaging.
Aim: We aimed to develop an automated diagnostic system for middle ear diseases by applying deep learning techniques to tympanic membrane images obtained during routine clinical practice.
Material And Methods: To augment the training dataset, we explored the use of generative adversarial networks (GANs) to produce high-quality synthetic tympanic images that were subsequently added to the training data.
Prevalence of High Frequency Noise-Induced Hearing Loss Among Medical Students Using Personalized Listening Devices.

Department of Otorhinolaryngology, Head and Neck Surgery, Bhaarath Medical College, Chennai 600073, Tamil Nadu, India.
The misuse of personalized listening devices (PLDs) resulting in noise-induced hearing loss (NIHL) has become a public health concern, especially among youths, including medical students. The occupational use of PLDs that produce high-intensity sounds amplifies the danger of cochlear deterioration and high-frequency NIHL especially when used in noisy environments. This study aims to evaluate the incidence and trends of NIHL among medical students using PLDs.
