The most important literature data concerning retraction pockets (RP) of the tympanic membrane and their currently accepted classification are presented. The objective of the present work was to develop criteria for the objective estimation of the dynamic state of the tympanic retraction pockets in children presenting with non-perforating forms of otitis media. A total of 138 children suffering from exudative otitis media were available for observation; retraction pockets were found in the majority of these patients. Otomicroscopic characteristics of various RP species are described. A diagnostic approach to the observation of the dynamic state of the tympanic retraction pockets is proposed. The presence of the retraction pockets of the tympanic membrane is considered to be a risk factor of the development of cholesteatoma and chronic purulent pathology of the middle ear in the children. Deep retraction pockets without a controllable bottom and attic cholesteatomas were identified in 16 (11.6%) and 6 (4.3%) of the examined children respectively. They were treated by means of sparing otosurgery.

Objective: This study aimed to assess the efficacy of a novel modified asymmetric chondro-perichondrial island graft in tympanoplasty. The design features a longer anterior segment compared to the posterior segment, addressing limitations of symmetrical grafts. We investigated the impact of this modified graft on hearing improvement and graft success rates in patients undergoing tympanoplasty surgery.

Article Synopsis
- Twiddler's syndrome is a rare condition associated with cardiac pacemakers, characterized by the twisting and retraction of the device lead within the implantation site.
- A 54-year-old woman was admitted to the emergency department due to chest pain and involuntary muscle contractions in her left side.
- A cardiology specialist confirmed the diagnosis of Twiddler's syndrome after evaluating the patient's symptoms.
Heterologous Materials Are Really Better than Autologous in Tympanoplasty Mastoid Obliteration? A Systematic Review with Meta-Analysis.

Article Synopsis
- - The study reviews literature from the past decade on mastoid obliteration in adults, comparing outcomes of autologous (patient's own tissue) vs. heterologous (donor tissue) grafts, using data from various medical databases.
- - A total of 37 studies were included, focusing on long-term results (over 12 months), highlighting that neither technique is definitively better, but both have unique benefits in cholesteatoma surgery.
- - The findings reveal that while heterologous grafts generally show lower rates of recurrent cholesteatoma, they have higher rates of complications like otorrhea and tympanic membrane perforations, illustrating a trade-off between the two graft types.

The present study aimed to evaluate the pneumatization status of the mastoid air cells in general with the depth and status of mastoid antrum in particular, in patients of chronic otitis media (COM). This is an observational cross-sectional study in sample size of 60 participants with large, subtotal perforation and posterosuperior retraction pocket (PSRP). Mean age with large central and subtotal perforation combined was 35.

Endoscopic middle ear surgery can be utilized to visualize and excise retraction pockets without the need for extensive bone work and removal of lateral bone. To evaluate the role of endoscope in the management of squamosal type of chronic otitis media. A total of 25 adults subjects (male = 12, female = 13) in the age group of 18-55 years suffering with chronic otitis media were operated by transcanal endoscopic approach.
