Abstract
OBJECTIVE To evaluate whether a combined translabyrinthine-transsphenoidal approach can be used to achieve adequate surgical resection of an extensive petrous bone cholesteatoma and create a debris drainage route for the residual cholesteatoma that is maintained long-term. PATIENT A 71-year-old man with residual petrous temporal bone cholesteatoma that had spread extensively to the internal carotid artery and posterior cranial fossa. INTERVENTION Surgical resection of the cholesteatoma via a translabyrinthine approach and creation of a debris drainage route into the nasopharynx via a transsphenoidal approach. MAIN OUTCOME MEASURES Control of unresectable petrous temporal bone cholesteatoma and occurrence of cholesteatoma- or surgery-related complications. RESULTS Although complete removal of the cholesteatoma was attempted via a translabyrinthine approach, this was not possible because the epithelium of the cholesteatoma was strongly attached to the internal carotid artery and posterior cranial fossa. A debris drainage route leading to the nasopharynx was created by drilling the clivus on the side of the lesion via a transsphenoidal approach. The patient has had no complications since surgery. The drainage route remains open, and the cholesteatoma has been controlled for 57 months. CONCLUSIONS A markedly advanced petrous temporal bone cholesteatoma can be managed safety and reliably by combining a translabyrinthine approach with a transsphenoidal approach. Creation of a debris drainage route into the nasopharynx can prevent isolation of the cholesteatoma and mastoid cavity problems after surgery. This one-stage surgery may be a suitable method for keeping cholesteatoma under control in patients with unresectable petrous bone cholesteatoma.

Abstract
BACKGROUND Endoscopic skull-base surgery (ESBS) is employed in the management of diverse skull-base pathologies. Paralleling the increased utilization of ESBS, the literature in this field has expanded rapidly. However, the rarity of these diseases, the inherent challenges of surgical studies, and the continued learning curve in ESBS have resulted in significant variability in the quality of the literature. To consolidate and critically appraise the available literature, experts in skull-base surgery have produced the International Consensus Statement on Endoscopic Skull-Base Surgery (ICAR:ESBS). METHODS Using previously described methodology, topics spanning the breadth of ESBS were identified and assigned a literature review, evidence-based review or evidence-based review with recommendations format. Subsequently, each topic was written and then reviewed by skull-base surgeons in both neurosurgery and otolaryngology. Following this iterative review process, the ICAR:ESBS document was synthesized and reviewed by all authors for consensus. RESULTS The ICAR:ESBS document addresses the role of ESBS in primary cerebrospinal fluid (CSF) rhinorrhea, intradural tumors, benign skull-base and orbital pathology, sinonasal malignancies, and clival lesions. Additionally, specific challenges in ESBS including endoscopic reconstruction and complication management were evaluated. CONCLUSION A critical review of the literature in ESBS demonstrates at least the equivalency of ESBS with alternative approaches in pathologies such as CSF rhinorrhea and pituitary adenoma as well as improved reconstructive techniques in reducing CSF leaks. Evidence-based recommendations are limited in other pathologies and these significant knowledge gaps call upon the skull-base community to embrace these opportunities and collaboratively address these shortcomings.

Abstract
Petrous apex cholesterol granulomas (PACG) are rare disorders that can lead to patient morbidity and must, occasionally, be drained by either endoscopic endonasal (EN) or open procedures (OP). The objective of our study was to complete a review of the literature to compare the EN and OP approaches on multiple levels, notably on safety and effectiveness. Ovid MEDLINE and Embase were used to perform a thorough literature review of all cases of PACG treated by either EN or OP dating from January 1948 to August 2017. In total, 49 articles were selected including 23 for EN (n=76) and 26 for OP (n=210). Differences were found in the incidence of preoperative hearing loss (HL) (EN 18.4%, OP 57.3%; p<0.001), headache (EN 48.7%, OP 31.2%; p=0.007), and disequilibrium (EN: 14.5%, OP 26.1%; p=0.04). Differences in lesion proximity to the sphenoid sinus (EN 23.6%, OP: 1.0%; p<0.001), clivus (EN 11.8%, OP 4.7%; p=0.03), otic capsule (EN 0.0%, OP 5.2%; p=0.03), internal auditory canal (EN 2.6%, OP 10.9%; p=0.01), and internal carotid artery (ICA) (EN 9.2%, OP 2.8%; p=0.02) were found on preoperative imaging. The EN procedure had better hearing improvement rates (EN 85.7%, OP 23.4%; p<0.001), lower complication rates (EN 7.9%, OP 17.6%; p=0.04), shorter median follow-up (EN:13.5 months, OP:37.2 months; p<0.001), and shorter time to recurrence (EN 3 months, OP 22.6 months; p=0.002) than the known OP. No differences were found in age, preoperative size, recurrence rate, operative time, stent placement, or improvement of other symptoms. Endoscopic nasal approaches, when feasible, should be favored to open procedures for PACG drainage given their better hearing improvement and less complication rates.

Abstract
Objective This study describes the safety and efficacy of mometasone furoate eluting stents in the management of petrous apex cholesterol granuloma approached through an endonasal endoscopic route and assesses the restenosis rate. Methods Consecutive patients undergoing endoscopic endonasal marsupialization of a petrous apex cholesterol granuloma at a tertiary referral center who had a mometasone furoate eluting stent placed intraoperatively were reviewed in a retrospective fashion. Postoperative endoscopy was used to determine success of surgery and stenting. Results Five patients were included in the study, three were primary cases and two patients had revision surgeries performed. The steroid eluting stent was placed successfully and safely in all patients with no dural or vascular injuries. The average follow-up duration was 10.6 months. There was no restenosis in three patients and one patient had an immediate restenosis that was debrided in clinic (revision case). This was patent at the 16 months follow-up. One patient also developed stenosis, 4 months after surgery due to sphenoid sinusitis. Conclusion Mometasone furoate eluting stents are safe and effective in the primary management of petrous apex cholesterol granuloma. Further studies are needed to assess their efficacy in revision cases and for long term results.

Abstract
PURPOSE OF REVIEW Lesions of the petrous apex of the temporal bone can be challenging to access and approaches laterally through the mastoid as well as medially through an endonasal approach are utilized to access this region while preserving function of adjacent structures. Cholesterol granulomas of the petrous apex requiring surgery are marsupialized to prevent expansion of the inflamed cyst and relieve associated clinical symptoms. The endonasal approach to the petrous apex has in the past been limited to lesions medial to the internal carotid artery. RECENT FINDINGS Endoscopic approaches have been developed to expand the range of petrous apex lesions that are accessible endonasally. These endonasal corridors include a nasopharyngeal/transclival corridor, lateralization of the internal carotid artery to create an expanded medial window, a pterygopalatine infrapetrosal approach, and a contralateral maxillary approach, which allow improved access to the inferior and lateral petrous apex. Nasoseptal flaps may reduce the risk of postoperative stenosis of the drainage tract. SUMMARY Endoscopic endonasal approaches can be used safely to address both medial and lateral/inferior petrous apex lesions. Morbidity of these procedures is low and use of a nasoseptal flap may limit restenosis of the drainage pathway.

Endoscopic transsphenoidal surgery using pedicle vascularized nasoseptal flap for cholesterol granuloma in petrous apex: A technical note. Neurol Neurochir Pol 2016; 50:504-510.

Abstract
BACKGROUND Compared with surgical resection, endoscopic transsphenoidal surgery (TSS) for cholesterol granuloma (CG) in the petrous apex (PA) is associated with local recurrence due to obstruction of the drainage route. We present a detailed procedure of an endoscopic TSS using pedicle vascularized nasoseptal flap (PVNF). METHODS A 40-year-old woman with a history of repeated surgery for left tympanitis was referred to our institution. Neurological examination revealed severe hearing loss in the left ear. Radiologic examination presented a round mass in the left PA and significant fluid collection in the mastoid air cells of the left temporal bone. CG was strongly suspected, and endoscopic TSS using PVNF was performed. Prior to endoscopic drainage, a PVNF was harvested from the mucosa of the ipsilateral nasal septum, with an attempt to preserve the sphenopalatine artery in the flap. Following this, puncture and adequate irrigation of the lesion was performed by endoscopic TSS, with neuro-navigation system assistance; the apex of PVNF was then placed into the lesion to prevent the obstruction of the drainage route. An absorbable polyglycolic acid sheet and fibrin glue were applied on the flap to prevent spontaneous deviation from the lesion. RESULTS The patient was discharged without any further neurological complications. Eight-month postoperative computed tomography images showed no recurrence; the drainage route was patent and the fluid collection in the left mastoid air cells was resolved. Moreover, hearing loss was improved. CONCLUSIONS Endoscopic TSS using PVNF may be one of available surgical options for PACG.

Abstract
Conclusion The sigmoid-incision (S-I) rescue flap technique has the advantage of both reduced-invasiveness and providing a sufficient surgical corridor for endoscopic endonasal skull base surgery (EESBS). Objective Skull base reconstruction with nasoseptal flap (NSF) is critically important in managing post-operative cerebrospinal fluid (CSF) leakage after tumor removal by EESBS. The NSF needs to be elevated before sphenoidotomy and posterior septectomy to preserve the pedicle. However, most extradural surgery without CSF leakage does not require NSF and, therefore, NSF preparation is often futile. As a result, a rescue flap technique to overcome this problem has been developed, whereby a new S-I rescue flap method is used that enables wide exposure of the sphenoidal rostrum and smooth manipulation of surgical instruments to preserve the NSF pedicle. Materials and methods Starting in April 2014, 19 cases underwent EESBS with S-I rescue flap. Results All patients underwent tumor resection under an adequate operative field with smooth manipulation of surgical instruments. Two complications were experienced. One patient had CSF leak after removal of the nasal packing, but the leakage was successfully closed by conventional NSF. Another patient had epistaxis from the septal wall, but this was controlled by electrocautery.
