“…The incidence of CC is estimated to be between 4 and 24% of all cholesteatomas in children, but presentations in adults are common and should not be overlooked [3,6,[11][12][13][14]. Although small middle ear lesions are sometimes set apart from petrous bone cholesteatomas, they should be taken as seriously as they grow and will eventually cause much damage [9,12,14,15].…”

“…Although the middle ear is the most typical localization, many sites can be involved including the mastoid process, the petrous bone, the external auditory canal, as well as intracranially. It represents 4-9% of all petrous pyramid lesions [3][4][5][6][7][8]. …”

Background: Congenital cholesteatomas (CC) arise from epithelial remnants around the petrous bone. They enlarge gradually causing progressive destruction and functional damage to the ear and surrounding structures. Because of their insidious course, most patients are misdiagnosed and present late with complications. Methods: This is a retrospective study of 41 cases diagnosed as CC and followed up for 2 years. All patients underwent full audiological evaluation and a radiological study (CT, MRI). Results: The male:female ratio was 2.3: 1, and the mean age was 30.89 years. The mean delay before presentation was 13 months. The commonest presentations in order of frequency were: discharge (60.9%), hearing loss (51.2%), facial paralysis (31.7%) and intracranial complications (31.7%). Forty patients were treated surgically by a variety of approaches depending on the extensions and functional status. The facial nerve was decompressed in 9 cases and cable grafted in 4. Two cases underwent VII-XII anastomosis later on. Conclusion: CC present with a myriad of clinical manifestations and should be suspected in all patients with unexplained otological signs and symptoms. They must be completely excised and the functional status of the ear rehabilitated either immediately or later. Follow-up must be indefinite as they have a high recurrence rate.

“…Exteriorization is favour in an only hearing ear and second choice of option when eradication is not possible. Otherwise, obliteration is applied in profuse cerebrospinal fluid leakage, large dural and carotid exposure, complete facial paralysis and profuse hearing loss [15,16].…”

The aim of this study is to present the clinical symptoms, complications and treatments of the petrous apex cholesteatoma and is to describe the current role of oto-endoscopy. This was a retrospective non-randomized study of 14 petrous apex cholesteatoma surgeries performed between 1994 and 2012. Petrosectomy was performed according to the location of the cholesteatoma, hearing level of the patients and facial nerve function. Oto-endoscopy was used in the petrous apex and the cerebellopontine angle for residual cholesteatoma. 14 patients, seven were men and seven women were included in this study between 1994-2012. The most common symptom was hearing loss (85.7 %) and tinnitus (50 %) at the presentation. During the surgeries, it was observed that cholesteatoma involved most frequently facial nerve, dura and labyrinthines. Labyrinthectomy, middle cranial fossa approach and petromastoidectomy was performed to these patients. Four of six patients operated without the endoscope assistance between 1994-2006 had recurrences after the operation. These patients were re-operated and in the follow up, there was no recurrence. In the endoscopy assisted surgery, there was no recurrence observed (significance level p = 0.014). The most common complication after the surgery was hearing loss (42.8 %) but it was not significant after surgery (p [ 0.05). The petrous apex and mastoid cavity was obliterated with fat tissue in eight patients while six patients were exteriorized to follow the recurrence and it was insignificant in recurrences (p [ 0.05) Conclusion: Endoscope-assisted surgery allows to remove residual the cholesteatoma around the carotid artery, dura and facial nerve in the petrous apex resulting in less invasive surgery and less recurrence in blind spots.

“…Two traditional techniques have been described in the literatures. Coker et al (1986) has done this technique for lateral approach to skull base through temporal bone. He has suggested Subtotal petrosectomy with tympanomastoid obliteration with blind sac closure provides a relatively safe and secure closure of the surgical defect in the temporal bone and eliminates the problems associated with an open mastoid cavity [18].…”

Brain herniation into the middle ear and mastoid is rare but is a described complication of chronic ear disease. The diagnosis is mainly clinical and requires a high index of suspicion. This can be confi rmed by imaging studies. Different surgical modalities have been described in managing this condition. We present a case managed by combined trans-mastoid mini-craniotomy approach and blind sac closure.
