What is Trip?
Trip is a clinical search engine designed to allow users to quickly and easily find and use high-quality research evidence to support their practice and/or care.
Trip has been online since 1997 and in that time has developed into the internet’s premier source of evidence-based content. Our motto is ‘Find evidence fast’ and this is something we aim to deliver for every single search.
As well as research evidence we also allow clinicians to search across other content types including images, videos, patient information leaflets, educational courses and news.

CholesteatomaCholesteatoma - NICE CKS Share Cholesteatoma: Summary A cholesteatoma is an abnormal sac of keratinizing squamous epithelium and accumulation of keratin within the middle ear or mastoid air cell spaces which can become infected and also erode neighbouring structures. A general practitioner with a list size of 2,500 patients would expect to see, on average, one new case of cholesteatoma every 4–5 years. Cholesteatoma may be asymptomatic in its early stages. Cholesteatoma most (...) commonly presents with a persistent or recurrent discharge from the ear that is often foul smelling. An associated conductive hearing loss may also occur. Rarely with progression of the disease, vertigo, sensorineural hearing loss, facial nerve palsy, meningitis, or intracranial abscess may develop. The diagnosis requires clear visualisation of the tympanic membrane. If the tympanic membrane can be seen, a cholesteatoma should be suspected if there is: Evidence of ear discharge. Presence of a deep

Although benign, it may enlarge and invade adjacent bone. Often presents with a malodorous ear discharge with associated hearing loss. Diagnosis is clinical (...) based on history and otoscopic findings. CT scan provides lesion definition and extent. Treatment is surgical removal. Adjunctive topical antimicrobial treatment may help reduce acute symptoms preoperatively. Complications include recurrence, meningitis, facial palsy, and a labyrinthine fistula. Definition Cholesteatoma is defined as the presence of keratinising squamous epithelium within the middle ear, or in other pneumatised areas of the temporal bone. Fisch U, May JS, Linder T.

Outpatient management of cholesteatoma with canal wall reconstruction tympanomastoidectomy The postoperative wound infection rate for canal wall reconstruction (CWR) tympanomastoidectomy with mastoid obliteration in the treatment of chronic otitis media with cholesteatoma has been reported to be 3.6%. Postoperative administration of 24-48 hours of intravenous antibiotics has been recommended. We aim to determine the infection rate of CWR with postoperative outpatient oral
Endoscopic transcanal modified canal-wall-down mastoidectomy for cholesteatoma Attic cholesteatoma with antral extension in tight sclerotic mastoid cavities is a common presentation that creates difficult decision-making intraoperatively. Drilling through a sclerotic and small mastoid cavity, keeping the canal wall intactis often difficult and increases the risk of serious injury. Consequently, a canal-wall-down mastoidectomy is often performed. The endoscopic transcanal modified canal-wall (...) -down mastoidectomy approach allows the benefits of an open cavity for cholesteatoma resection and the benefits of a closed cavity for better long-term care and a more normal ear canal and middle ear reconstruction.
Congenital cholesteatoma: Different clinical presentation in two cases Congenital cholesteatoma (CC) of the middle ear is a rare entity that may be undiagnosed for years. The lesion can grow undetected until it produces symptoms such as reduced hearing or otalgia.Case report.We report two cases of young ladies with CC who presented with different otological symptoms. The first case complained of recurrent unilateral ear pain while the second case presented with unilateral reduced hearing
Giant Petrous Bone Cholesteatoma: Combined Microscopic Surgery and an Adjuvant Endoscopic Approach Petrous bone cholesteatomas (PBCs) are epidermoid cysts, which have developed in the petrous portion of the temporal bone and may be congenital or acquired. Cholesteatomas arising in this region have a tendency to invade bone and functional structures and the middle and posterior fossae reaching an extensive size. Traditionally, surgery of a giant PBC contemplates lateral transtemporal or middle (...) fossa microscopic surgery; however, in recent years, endoscopic surgical techniques (primary or complementary endoscopic approach) are starting to receive a greater consensus for middle ear and mastoid surgeries. We report the rare case of an 83-year-old Caucasian male affected by a giant cholesteatoma that eroded the labyrinth and the posterior fossa dura and extended to the infralabyrinthine region, going beyond the theca and reaching the first cervical vertebra. The giant cholesteatoma

Otoscopy therefore represents the most reliable and sensitive means of diagnosing a cholesteatoma. In pathological terms cholesteatoma is simply benign keratinising squamous epithelium that forms a cyst within the middle ear or mastoid
