Cholesteatoma*

Objective: To determine the stage of middle ear cholesteatoma of patients who underwent middle ear surgery at the Southern Philippines Medical Center from January to December 2019, based on European Academy of Otology and Neurotology / Japan Otological Society (EAONO/JOS) system. Methods: Design: Case Series. Setting: Tertiary Government Hospital. Participants: A total of 42 charts were included in the study. Results: Of the 42 cases evaluated, congenital cholesteatoma was seen in 4 while acquired cholesteatoma was noted in 38, (further subdivided into 34 retraction pocket cholesteatoma and 4 non-retraction pocket/traumatic cholesteatoma). A majority (57%) had Stage II cholesteatoma (mass occupying at least two sub-sites in the middle ear) at the time of surgery. Eight (19%) had stage I cholesteatoma (confined to one sub-site), five (12%) had stage III cholesteatoma evidenced by extracranial complications such as subperiosteal abscess and erosion of the semi[1]circular canals. Stage IV cholesteatoma was seen in 5 (12%) presenting with intracranial abscess. Canal wall down mastoidectomy was the most common surgical approach performed. The sinus tympani (S2 ) was the most commonly involved difficult to access site across all classifications of middle ear cholesteatoma (60%). Conclusion Our study provided an initial profile of the stages and severity of middle ear cholesteatoma in our institution based on actual surgical approaches. Such a profile can be the nidus for a database that can help us to understand disease prevalence and compare local surgical practices with those in the international community.

Literature has reported the existence of cholesteatoma in chronic suppurative otitis media with tuberculosis. This report demonstrates that a cholesteatoma can be associated with an acute otitis media with tuberculosis. The importance of a high index of suspicion for tuberculous otitis media and its consequent meticulous management including diagnostic tests, medical and surgical procedures and monitoring are discussed.

Objective:To describe the radiologic dimensions of the Eustachian tube (pre-tympanic diameter, tubo-tympanic angle, and Eustachian tube angle) among normal ears, ears with chronic otitis media (COM) with and without cholesteatoma, in a sample of Filipino adults with COM; and to compare the dimensions of the three variables.

Methods:
Design:Retrospective Review of Records
Setting:Tertiary Government Training Hospital
Participants:The study included 69 CT scans of adults with COM, with images of 23 ears for each variable (normal ears, COM with and without cholesteatoma formation).

Results:In normal ears, the average pre-tympanic diameter was 3.976 ± 0.78 mm, the average tubo-tympanic angle was 41.529 ± 5.85 degrees, and the average Eustachian tube Angle (Reid Plane) was 27.077 ± 4.62 degrees. In patients with COM without cholesteatoma, the mean pre tympanic diameter was 4.002 ± 1.13 mm, the mean tubo-tympanic angle was 141.994 ± 6.30 degrees, and the mean measurement of the Reid plane was 24.649 ± 3.10 degrees. In ears with COM with cholesteatoma, the mean pre-tympanic diameter was 4.1993 ± 0.50mm, the mean tubo-tympanic angle was 138.789 ± 7.13 degrees, and the mean Reid plane was 26.483 ± 3.86 degrees. P-values for the pre-tympanic diameter, tubo-tympanic angle, and ET angle were .617, .198, and .098 respectively, indicating that there were no statistically significant differences in the ET dimensions of the ears with COM with cholesteatoma, without cholesteatoma and normal ears.

Conclusion:In our investigation, we found no statistically significant differences in Eustachian tube dimensions among individuals with normal ears and COM with or without cholesteatoma. This suggests that the Eustachian tube dimensions may not serve as a primary etiological factor for COM among our patients.

Introduction: Cholesteatoma is an aggressive disease and its management poses a greater challenge in children than in adults. This study reviews the experience of Universiti Kebangsaan Malaysia Medical Centre in the clinical presentation and management outcome of acquired cholesteatoma in paediatrics that required surgical interventions. Materials and Methods: A retrospective review of case records of patients below 18 years old who underwent surgery from 1999 to 2010. Results: A total of 46 patients presented with 53 cases of cholesteatoma in which seven patients had bilateral disease. The age of presentation ranged from four to 18 years old with a mean age of 12 years. Male and female patients were 65% and 35% respectively. Otorrhoea or previous history of otorrhoea on presentation was found in 94% and 96% of them had hearing impairment. Cerebellopontine angle abscess, sigmoid sinus thrombosis and mastoiditis were among the complications. Tympanic membrane was retracted in 64% while 47% having had attic retraction and 53% had total atelectasis. A majority (85%) underwent canal wall down surgery with or without tympanoplasty. Post-operatively, 71% had improvement or preserved hearing level. The duration of follow up ranged from one month to 13 years and a quarter had recurrent disease and underwent revision surgeries. Conclusion: Majority of the cholesteatoma patients suffered from hearing loss and otorrhoea. Tympanic membrane retraction remained the most common clinical finding. Hence, children with persistent otorrhoea after adequate treatment may represent cholesteatoma. Surgical options of canal wall up and canal wall down procedures have equal risk of recurrence.

Cholesteatoma is a serious disease of the ear. It is defined as a benign skin lesion that grows in the middle ear cleft. The most commonly affected sites are the middle ear cavity and mastoid bone. It can also develop in the petrous apex. It can manifest with a wide range of symptoms ranging from persistent ear discharge to hearing loss. The treatment is almost always surgical excision. We report a rare case of middle ear cholesteatoma that presented as an aural polyp arising from the posterior wall of the external auditory canal.

Several theories have been advanced to explain the formation of primary acquired or attic refraction Cholesteatomas including invagination of the pars flaccida, basal cell hyperplasia, otitis media with effusion, and perforation of the pars flaccida membrane with epithelial ingrowth. The study suggests it is the VA to be the cause of the otitis media with effusion and the attic Cholesteatomas.

A 14-year old female with Down syndrome presented with a 3-year history of recurrent purulent left otorrhea. The discharge had become more frequently blood-tinged. Otologic examination revealed a stenotic ear canal with polypoid granulation obstructing the view of the tympanic membrane. High resolution computerized tomographic (HRCT) imaging of the temporal bone was performed to assess the status of the middle ear and mastoid. Particular attention was given to assess for bony erosion associated with cholesteatoma formation.
