Importance: Tympanic membrane retraction (TMR) is a relatively common otological finding. However, no consensus on its management exists. We are looking especially for a treatment strategy in the military population who are unable to attend frequent follow-up visits, and who experience relatively more barotrauma at great heights and depths and easily suffer from otitis externa from less hygienic circumstances.
Objective: To assess and summarize the available evidence for the effectiveness of surgical interventions and watchful waiting policy in patients with a tympanic membrane retraction.
Evidence Review: The protocol for this systematic review was published at Prospero (207859). PubMed, Embase, and the Cochrane Database of Systematic Reviews were systematically searched from inception up to September 2020 for published and unpublished studies. We included randomized trials and observational studies that investigated surgical interventions (tympanoplasty, ventilation tube insertion) and wait-and-see policy. The primary outcomes of this study were clinical remission of the tympanic membrane retraction, tympanic membrane perforations and cholesteatoma development.
Findings: In total, 27 studies were included, consisting of 1566 patients with TMRs. We included data from 2 randomized controlled trials (76 patients) and 25 observational studies (1490 patients). Seven studies (329 patients) investigated excision of the TMR with and without ventilation tube placement, 3 studies (207 patients) investigated the wait-and-see policy and 17 studies (1030 patients) investigated tympanoplasty for the treatment of TMRs.
Conclusions And Relevance: This study provides all the studies that have been published on the surgical management and wait-and-policy for tympanic membrane retractions. No high level of evidence comparative studies has been performed. The evidence for the management of tympanic membrane retractions is heterogenous and depends on many factors such as the patient population, location and severity of the TMR and presence of other ear pathologies (e.g., perforation, risk of cholesteatoma and serous otitis media).

Acute necrotizing otitis media is a severe middle ear infection which causes necrosis of the tympanic cavity. A 54-year-old female was presented who suffered from diabetes mellitus and end-stage renal disease presenting with severe otalgia, initially thought to be necrotizing otitis externa. She rapidly progressed to total necrosis of the tympanic membrane.

An animal's body mass is said to be indirectly related to its rate of heat loss; that is, smaller animals with higher surface area to volume tend to lose heat faster than larger animals. Thus, thermoregulation should be related to body size, however, generalizable patterns are still unclear. Domestic dogs are a diverse species of endothermic mammals, including a 44-fold difference in body size.

Background: Myringoplasty is one of the treatments used for perforated tympanic membrane.
Aim/objective: We aimed to evaluate the long-term anatomical and functional outcomes of patients who underwent endoscopic inlay butterfly cartilage myringoplasty.
Material And Methods: We retrospectively analyzed 74 patients who had undergone endoscopic butterfly cartilage myringoplasty were followed for at least five years.

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.

Background: Although Cochlear implantation (CI) is effective in restoring hearing for children with severe-to-profound sensorineural hearing loss, it may influence the middle ear mechanics, potentially causing an air-bone gap and altering middle ear stiffness, which is not detected by traditional 226 Hz tympanometry.
Aims/objectives: To investigate the effect of mastoidectomy posterior tympanotomy (MPTA) on wideband absorbance (WBA) in children with CI.
Materials And Methods: The study included 20 normal-hearing children (normal group) and 10 children with CIs who underwent MPTA (CI-MPTA group), aged 3-10 years.
