A case of osteoma with cholesteatoma of the external auditory canal and cerebellar abscess

A case of external auditory canal osteoma complicated with cholesteatoma, mastoiditis, labyrinthitis and internal auditory canal pachymeningitis

The association between external auditory canal osteoma and external auditory canal cholesteatoma is rare, with only a few reports in the current literature. Intracranial complications are very rare in the external auditory canal cholesteatoma, especially with direct propagation through the internal auditory canal. A case of 27-year-old male presenting with external auditory canal osteoma with secondary external auditory canal cholesteatoma is described. Progression of the disease created in turn a mastoiditis, labyrinthitis and pachymeningitis confined to the internal auditory canal. The patient was treated by a subtotal petrosectomy, without entering the internal auditory canal. A control MRI after 3 months showed reduction of the internal auditory canal enhancement.

Osteomas of Temporal Bone: A Retrospective Study

Osteomas of temporal bone are rare, slow growing benign tumours and they are reported in all parts of temporal bone. This study is a retrospective study of the clinical presentation, management and complications of temporal bone osteoma done from January 1999 through January 2017. The study population is thirteen patients, all who has been radiologically and histopathologically proven to be a case of osteoma. Total number of patients were 13 of which 7 were females and rest 6 were male. Presenting complaints included swelling behind the ear (6 cases), reduced hearing in 4 cases, 2 cases had ear discharge, 3 of them were asymptomatic in whom it was diagnosed accidently. The duration of symptoms ranged from 1 month to 10 years. Of total 13 patients 7 had external auditory canal involvement and 4 cases had mastoid region. Two patients were managed conservatively, one refused surgery and rest ten cases underwent excision. The specimen was sent for histopathological examination and diagnosis of osteoma was confirmed. The decision regarding whether to operate or not depends on each case depending on its size, symptoms and more importantly the complications. Excision of osteoma remains the treatment of choice.

Peripheral osteoma of the hard palate

Peripheral osteomas of the hard palate are relatively rare. Two cases of osteoma of the hard palate are reported, along with a review of the literature.

Osteoma with cholesteatoma of the external auditory canal: neck manifestation of this rare association†

Osteoma and cholesteatoma of the external auditory canal is a rare clinical finding, presenting specific challenges in patients suffering from this dual pathology of the ear. We report on a unique complication of this association in a patient suffering with recurrent neck abscesses. Neck disease secondary to cholesteatoma has become nearly extinct with better clinical imaging and sensible antibiotic usage.

Characteristics of osteoma of the temporal bone in young adolescents

The author conducted a retrospective review of the clinical presentation, management, and complications of temporal bone osteoma in young adolescents. The study population was made up of 9 patients-5 girls and 4 boys, aged 12 to 15 years at presentation (mean: 13.7)-who had been seen for radiologically and histopathologically proven temporal bone osteoma at the author's institution over a 9-year period. Of this group, 5 patients had extracanalicular osteoma (3 in the mastoid portion of the temporal bone, 1 in the squamous portion, and 1 in the mastoid antrum) and 4 patients had osteoma of the external auditory canal. Six of the 9 patients underwent surgical treatment; of the remainder, 1 refused surgery and 2 were managed conservatively with ongoing observation. All patients were followed for a minimum of 1 year, and no recurrences and no complications were observed during that time.

Therapeutic approaches to complicated cholesteatoma of the external auditory canal: a case of associated facial paresis

Spontaneous cholesteatoma of the external auditory canal (EAC) is an uncommon condition that is difficult to diagnose. In a patient with such a possibility, serious clinical investigation along with radiologic and histologic exploration should be performed early on because a delay in treatment can lead to severe complications. Given the rarity of EAC cholesteatoma, no therapeutic consensus has emerged. The type of management depends on the extensiveness of invasion and bone erosion and the status of the neighboring structures. The primary therapeutic objectives are to eradicate the cholesteatoma and then to fill in the residual cavity, which in our opinion can be best accomplished with a muscle flap and EAC reconstruction. Postoperative follow-up should be carried out to look for infections, stenosis, and recurrence. We report a new case of spontaneous EAC cholesteatoma, and we review its diagnostic and therapeutic challenges.
