“…Senn et al [7] reported in their study that hearing preservation was feasible [7]. Kim et al [8] reported in their study that preserving the hearing level was possible in supralabyrinthine type with appropriate surgery. It is possible to have control on cholesteatoma extending from medial side of superior semicircular canal to internal acoustic canal and geniculate ganglion by middle fossa and trans mastoid approach together, so we had this operation in one patient mentioned above.…”

Introduction: Petrous bone cholesteatoma Petrous bone cholesteatoma (PBC) is defined as cholesteatoma extending medial to otic capsule. Because of its relations with vital structures, surgical management is generally difficult. Objective: In this study, we aim to share our clinical experiences about surgical approaches, managements and follow up results in petrous bone cholesteatoma.Methods: A retrospective clinical study was conducted on patients who had been diagnosed as PBC between 2003 and 2012 years. Sanna classification was used for the pathology extending. A total of 13 patients with 14 ears were evaluated about symptoms, clinical and radiological findings, surgical techniques, complications and follow up results. Results:The mean age of patients was 33,3 years ranging from 18 to 52 years. Hearing loss was the most common symptom (92 %). Five patients had facial paralysis preoperatively. Massive type was the most common type. Different surgical techniques were carried out for each pathological type. Mean follow up time was 34,3 months. Recurrence was identified in one patient twice within two years and revision surgical procedures were performed. Conclusion:Extent of the PBC should be well defined in preoperative imaging and type of surgical approach should be planned before with an appropriate classification. Regular follow up is mandatory for patients with MRI every year.

The petrous apex is a pyramid-shaped structure that is formed by the medial portions of the temporal bone. It is obliquely positioned within the skull base, with its apex pointing anteromedially and its base located posterolaterally. The petrous apex is bounded by the inner ear structures laterally, the petro-occipital fissure medially, the petrosphenoidal fissure and ICA anteriorly, and the posterior cranial fossa behind. Given its location, the petrous apex is susceptible to multiple pathologic processes which may be Inflammatory, developmental, vascular, benign and malignant lesions. We present a rare case of a 39 year old Male who presented wit unilateral facial nerve palsy and sensoneural hearing loss and was then diagnosed as petrous apex Cholesteatoma. Patient was treated surgically by Transchoclear trasnlabrynth technique.

“…PBCs have been shown to be locally aggressive by involving the petrous bone and the areas surrounding it like the clivus, nasopharynx, sphenoid sinus, and infratemporal fossa and even extending intradurally [Lin et al, 2009;Pandya et al, 2010;Rijuneeta et al, 2008;Sanna et al, 1993]. Also, the close proximity of the disease to the labyrinth and the facial nerve (FN) puts to risk both hearing and FN function, which is reflected in the high incidence of FN palsy (34.6-100%) seen in the important series reported in the literature [Kim et al, 2014;Magliulo, 2007;Moffat et al, 2008;Sanna et al, 2011;Yanagihara et al, 1992]. The classification proposed by Sanna et al [Pandya et al, 2010;Sanna et al, 1993Sanna et al, , 2011, which is now widely accepted, divides PBCs into five groups based on the relationship of the disease to the labyrinthine block.…”

Objective: To review the classification and management of petrous bone cholesteatomas (PBCs) at our center and the outcomes of facial nerve (FN) management in these lesions. Methods: This was a retrospective study. The setting was a quaternary referral center for skull base pathology in Italy. A total of 200 patients with 201 PBCs were included in the study. All patients diagnosed radiologically with PBCs were classified according to the Sanna classification. All patients were surgically treated and followed up with radiology. The main outcome measures - classification of PBCs, the surgical approach used, disease control, and FN outcomes - were analyzed. Results: Supralabyrinthine PBCs were the most common type with 92 cases (45.8%) followed by the massive PBCs with 72 cases (35.8%). Preservation of preoperative FN function was highest in the infralabyrinthine (72.2%) and infralabyrinthine-apical (73.3%) types. The transotic approach was used in 66 cases (32.8%) in this series. The modified transcochlear approach type A was applied in 55 cases (27.3%). Active management of the nerve (rerouting, anastomosis, or grafting) was required in 53 cases (26.4%). Postoperatively, of the 116 cases with FN House-Brackmann grade I and II, 107 cases (92.2%) retained the same grade or improved. Recurrence was seen in 7 cases (3.5%). The mean duration of follow-up was 6.3 years. Conclusions: Radical disease clearance must take precedence over hearing and FN preservation in PBCs. Active FN management, including rerouting, end-to-end anastomosis, and cable nerve grafting, routinely come to play in the surgical management of PBCs, and the postoperative FN results after such interventions can be satisfactory in most cases.
