Intratympanic membrane cholesteatoma after traumatic tympanic membrane perforation: a case report

Journal of Medical Case Reports, 2023
Background Intratympanic membrane cholesteatoma presents as an asymptomatic, white, round mass on the tympanic membrane, and is usually detected incidentally in children.

Defining the Terminology for Acute Ear Discharge in Children: Systematic Review and Expert Consensus Using the Nominal Group Technique

Clinical Otolaryngology, Volume 50, Issue 6, Page 951-960, November 2025.
ABSTRACT Background Acute otitis media (AOM) is one of the most frequent paediatric infections. In approximately 15% of children with AOM, the tympanic membrane perforates, leading to ear discharge. This subset of children is usually more unwell and may need different treatment than those without a perforation.

Extensive Tympanic Membrane Cholesteatoma with Marginal Perforation: An Unusual Case

Case Reports in Otolaryngology, 2013
The migration of squamous epithelium of external ear through a tympanic membrane perforation into the middle ear forms a cholesteatoma. But it is extremely a rare condition to observe extensive cholesteatoma on the medial surface of tympanic membrane ...

Stem cells in middle ear cholesteatoma contribute to its pathogenesis

Scientific Reports, 2018
Cholesteatoma is a potentially life-threatening middle ear lesion due to the formation of an inflamed ectopic mass of keratinizing squamous epithelium.

Spontaneous external auditory canal cholesteatoma in a young male: Imaging findings and differential diagnoses

Indian Journal of Radiology and Imaging, 2016
A cholesteatoma is a non-neoplastic lesion of the petrous temporal bone commonly described as “skin in the wrong place.” It typically arises within the middle ear cavity, may drain externally via tympanic membrane (mural type), or may originate in the ...

Microarray Analysis of Differentially-expressed MicroRNAs in Acquired Middle Ear Cholesteatoma

International Journal of Medical Sciences, 2018
Objectives: To analyze the miRNAs expression profiling between acquired middle ear cholesteatoma and normal skin, and to identify several novel miRNAs which may be involved in the etiopathogenesis of middle ear cholesteatoma.

Pediatric Hairy Polyp of the Naso‐Oropharynx: A Case Report and Systematic Literature Review

Laryngoscope Investigative Otolaryngology, Volume 10, Issue 5, October 2025.
ABSTRACT Introduction Hairy polyps (HPs), also known as bigerminal choristoma, are rare tumors most often occurring within the nasopharynx and oropharynx, linked to the development of the first and second pharyngeal arches. Commonly, HPs present in female neonates and are left‐sided.

Non-echoplanar diffusion weighted imaging in the detection of post-operative middle ear cholesteatoma: navigating beyond the pitfalls to find the pearl

Insights into Imaging, 2016
Non-echoplanar diffusion weighted magnetic resonance imaging (DWI) has established itself as the modality of choice in detecting and localising post-operative middle ear cleft cholesteatoma.

Unmasking Rarity: An Atypical Presentation of Lemierre's Syndrome

Clinical Case Reports, Volume 13, Issue 9, September 2025.
ABSTRACT Lemierre's syndrome (LS), otherwise known as postanginal sepsis, is a frequently overlooked condition characterized by septic thrombophlebitis of the internal jugular vein (IJV), usually caused by oropharyngeal infection. However, ear space (otogenic) infections are one of the atypical causes of LS and have been rarely reported.
