Otitis Media4
Congenital8
  • Congenital cholesteatomas are usually middle ear epidermal cysts that are identified deep within an intact ear drum. (wikipedia.org)
  • Keratin-filled cysts that grow medial to the tympanic membrane are considered to be congenital if they fulfill the following criteria (Levenson's criteria): mass medial to the tympanic membrane normal tympanic membrane no previous history of ear discharge, perforation or ear surgery Congenital cholesteatomas occur at three important sites: the middle ear, the petrous apex, and the cerebropontinio angle. (wikipedia.org)
  • They are most often found deep to the anterior aspect of the ear drum, and a vestigial structure, the epidermoid formation, from which congenital cholesteatoma may originate, has been identified in this area. (wikipedia.org)
  • Congenital cholesteatoma form in the middle ear or in other areas of the ear. (factdr.com)
  • Additionally, we report the second case of bilateral congenital middle ear lipoma. (bvsalud.org)
  • The most common location of the masses is in the anterosuperior quadrant of the middle ear, the site of predilection for small congenital cholesteatomas. (bvsalud.org)
  • Finally, another rare type of cholesteatoma is present at birth (congenital) and is related to how the ear develops. (drmaddox.net)
  • He has specific clinical interests in congenital hearing loss, congenital ear anomalies, pediatric cochlear implantation, microtia and atresia reconstruction, and bone conduction implants. (stanford.edu)
Formation of cholesteatoma4
  • This abnormal folding or 'retraction' of the tympanic membrane arises in one of the following ways: Jackler's theory: Mucosal coupling with traction generated by interaction of migrating opposing surfaces leading to formation of cholesteatoma. (wikipedia.org)
  • Wittmaack's theory: Invagination of tympanic membrane from the attic or part of pars tensa in the form of retraction pockets lead to the formation of cholesteatoma. (wikipedia.org)
  • Squamous epithelium collects in this retraction pocket leading to the formation of cholesteatoma after a few years. (factdr.com)
  • Even after 300 years of its identification, there is still no exact pathogenesis for the formation of cholesteatoma. (healthadvicer.com)
Mastoidectomy6
Tympanoplasty4
  • Tympanoplasty in most cases is an elective procedure, meaning that it can be scheduled whenever the patient is ready to have it done. (alghareebmc.com)
  • Depending on the unique circumstances, a patient might also receive a tympanoplasty and ossicular (hearing) reconstruction. (neilsperlingmd.com)
  • Tympanoplasty is the surgical reconstruction of the eardrum and hearing apparatus. (neilsperlingmd.com)
  • Cartilage-perichondrium island graft may be preferred for reconstruction of the tympanic membrane because of its resistance to inflammation and poor feeding in revision tympanoplasty. (advancedotology.org)
Eardrum6
  • Cholesteatoma is an abnormal non-cancerous skin growth or skin cyst that develops behind the eardrum, in the middle section of the year. (factdr.com)
  • Cholesteatoma is an abnormal skin growth or skin cyst trapped behind the eardrum, or the bone behind the ear. (drmaddox.net)
  • Cholesteatomas begin as a build-up of ear wax and skin, which causes either a lump on the eardrum or an eardrum retraction pocket. (drmaddox.net)
  • A cholesteatoma can develop when skin of the ear canal passes through a hole in the eardrum and into the middle ear space. (drmaddox.net)
  • Cholesteatoma is a benign growth caused by the build-up of skin cells and protein from the ear canal behind the eardrum that may need to be removed with cholesteatoma surgery. (neilsperlingmd.com)
  • If, however, a bit of this skin penetrates the eardrum - which can occur for a number of reasons - the keratin that continues to be given off by the skin becomes trapped in the middle ear and builds-up over time, resulting in a cholesteatoma. (neilsperlingmd.com)

  • Cholesteatoma in an advanced stage breaks the ear bones and the infection is severe enough to cause damage to temporal bones on the back of the skull resulting in complications of CNS or the central nervous system. (healthadvicer.com)
  • In a few cases, such as a significant infection or a cholesteatoma, this procedure may prevent more significant damage to the ear and the surgery may need to be performed more urgently. (alghareebmc.com)
Surgery16
