Laryngoscope 2024; 134:1540-1550. [PMID: 37812326 DOI: 10.1002/lary.31073] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2023] [Revised: 08/10/2023] [Accepted: 09/11/2023] [Indexed: 10/10/2023]
Abstract
OBJECTIVE To compare the outcomes of different surgical approaches to petrous apex cholesterol granulomas (PACG). DATA SOURCES PubMed, Embase, Google Scholar, Cochrane, and Web of Science. REVIEW METHODS Following the Preferred Reporting Items for Systematic Reviews and Meta-analyses-Network Meta-analyses guidelines, databases were searched from inception to November 31, 2022. Studies comparing two or more approaches were included. Reviews and population studies were excluded. The main outcome measures were the resolution of symptoms, serviceable hearing, complication, and revision rates. RESULTS The search yielded 2132 studies. After applying inclusion and exclusion criteria, 15 studies remained, consisting of 214 patients treated with lateral approaches (n = 182) or anterior endonasal approaches (n = 32). The efficacy of lateral and anterior endonasal approaches in achieving symptom resolution was comparable (73% vs. 68%, p = 0.5). Both exhibited similar rates of complications (33% vs. 37%, p = 0.3), albeit with distinct profiles. Lateral approaches were associated with higher rates of facial palsy and sensorineural hearing loss (44% vs. 18%, p = 0.03). Anterior endonasal approaches demonstrated higher rates of epistaxis and cerebrospinal fluid leak (15% vs. 1%, p = 0.001). Anterior endonasal approaches exhibited lower revision rates (OR: 0.35, 95% CI: 0.14-0.88). The placement of a stent in both approaches was associated with higher symptom resolution (OR: 5.12, 95% CI: 1.05-9.97) and lower revision rates (OR: 0.71, 95% CI: 0.33-0.92). CONCLUSIONS Anterior endonasal approaches yield lower revision rates compared to lateral approaches for PACG. Both approaches demonstrate similar effectiveness in symptom resolution and comparable rates of complications, with distinct profiles. Facial nerve and hearing status are important factors that should be addressed when selecting the approach. Stenting is beneficial. LEVEL OF EVIDENCE NA Laryngoscope, 134:1540-1550, 2024.

Abstract
BACKGROUND To treat extradural solid-cystic lesions of the ventral skull base, a pedicled nasoseptal flap (NSF) maintains patency of the marsupialized cavity and prevents restenosis and cyst recurrence. METHODS The authors provide a step-by-step description of the surgical technique valid in different lesions of the skull base, all treated via the endoscopic endonasal approach (EEA). The application is demonstrated by an operative video. CONCLUSION In selected lesions, endoscopic marsupialization using an NSF ensures drainage and ventilation of the surgical cavity. Re-epithelialization provided by a pedicled flap is a viable alternative to multilayer skull base reconstruction.

Abstract
Introduction The endoscopic endonasal transpterygoid approach (EETPA) with or without the addition of the endoscopic-assisted sublabial anterior transmaxillary approach (ESTA) has become increasingly utilized for lesions posterior to the pterygopalatine fossa (PPF), including infratemporal fossa (ITF), lateral recess of the sphenoid sinus, Meckel's cave, petrous apex, and parapharyngeal space. The main goal of this study is to develop an educational resource to learn the steps of the EETPA for trainees. Methods EETPA and ESTA were performed in 12 specimens by neurosurgery trainees, under supervision from the senior authors. One EETPA and one ESTA were performed on each specimen on opposite sides. Dissections were supplemented with representative cases. Results After a wide unilateral sphenoidotomy, ethmoidectomy, and partial medial maxillectomy, the anteromedial bone limits of the PPF were identified and drilled out. The pterygoid progress was modularly removed. By enlarging the opening of the posterior and lateral walls of the maxillary sinus through EETPA and ESTA, respectively, the neurovascular and muscular compartments of the PPF and ITF were better identified. The EETPA opens direct corridors to the PPF, medial ITF, middle cranial fossa, cavernous sinus, Meckel's cave, petrous apex, and internal carotid artery. If a more lateral exposure of the ITF is needed, the ESTA is an appropriate addition. Conclusion Despite the steep learning curve of the EETPA, granular knowledge of its surgical anatomy and basic surgical steps are vital for those advancing their learning in complex endoscopic approaches to the ventral skull base when expanding the approach laterally in the coronal plane.

Abstract
At present an exclusive endoscopic endonasal approach is sufficient in the majority of cases to treat pathologies involving the sinonasal compartment and the surrounding anatomical subsites (e.g. orbit, ventral skull base, upper parapharyngeal space, etc.) with the advantage of minimising surgical invasiveness. In this context, nasal vascularised local flaps are widely employed because they represent a more effective option for reconstruction or preservation of noble/vital structures compared to grafts. On the other hand, the surgical extension and morbidity are minimised compared to regional or free flaps. Several nasal local flaps have been described in the literature: the aim of this review is to examine their applications, characteristics, indications, success rates and morbidities. Different nasal flaps based on single or multiple pedicles have been described; the choice between them is based on different factors such as the flap’s shape and dimension, localisation of the pedicle’s origin, width of rotation angle, previous surgeries which could compromise vascularisation, and surgical experience, in addition to the position and dimension of the area which must be resurfaced.

Abstract
Background Rathke's cleft cysts (RCCs) are benign epithelial lesions arising from the Rathke's pouch remnants that fail to regress during embryogenesis. Some RCCs become symptomatic and require treatment. Cyst fenestration and drainage of its contents is the preferred procedure to treat symptomatic cases but carries a risk of recurrence. We propose the use of a novel modified nasoseptal flap technique to partially line the cyst wall to avoid recurrence. Methods This was a prospective, observational study that included all RCC patients admitted to the Department of Neurosurgery, Aster Medcity, from April 2015 to May 2018. The modified nasoseptal flap technique was performed in all patients. They underwent preoperative and postoperative ophthalmological, endocrine, endoscopic, and MRI evaluations to look for recurrence. Results Ten patients underwent the modified nasoseptal flap technique. The median follow-up was 36 months. Postoperatively, all patients were relieved from headaches. Moreover, their visual fields and pituitary functions normalized. None of the patients developed recurrence of RCC on follow-up brain MRI. On endoscopic examination, all patients had retained patency of the fenestra. The longest follow-up was 72 months. Conclusions The modified nasoseptal flap technique maintains patency and avoids recurrence of RCCs on long-term follow-up.

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
OBJECTIVES Surgical treatment of temporo-sphenoidal meningoceles involves the reduction of the meningocele, watertight closure and defect coverage with a nasoseptal flap (NSF). It can be performed contralaterally or ipsilaterally: in the latter situation, the pedicle of the flap must be dissected into the pterygopalatine fossa. The objective of this study was to evaluate the benefit of using an ipsilateral NSF in transpterygoid approaches for the management of temporo-sphenoidal meningoceles, compared to a contralateral NSF, based on a radiological study. MATERIAL AND METHODS Retrospective monocentric study of 21 cases, between 2002 and 2018. Measurement of the NSF lengths, and lengths needed to cover the defect were evaluated on the preoperative scanner. Early and later failure and complication rates were evaluated. RESULTS Seventeen cases of temporo-sphenoidal meningoceles with available CT scan were identified. The mean duration of follow up was 27.9 months [1-147]. Theoretical lengths of the ipsi and contralateral NSF were comparable: 71.4±7.8mm vs. 78.8±8mm, P=0.729. In 8 cases/18 (42%), the theoretical length of the contralateral NSF was not long enough to cover the defect beyond the V2 (mean lack of 8.87±6.6mm). In all cases, the theoretical length of the ipsilateral NSF was sufficient to cover the defect. In the case series, failure and complication rates were similar. CONCLUSION The use of an ipsilateral NSF for the transpterygoid management of temporo-sphenoidal meningoceles, although more complex, allows a better coverage of the defect, compared to the contralateral NSF, which is not long enough in 42% of cases.

Abstract
OBJECTIVES Rathke cleft cysts (RCCs) are rare, benign lesions formed from remnants of Rathke pouch during embryologic development. However, following marsupialization, maintaining tract patency remains a challenge. Several techniques for decreasing stenosis have been described, including free mucosal grafting, silastic spacing, and using steroid-eluting stents. Nasoseptal flaps (NSFs) have a reliable vascular supply and are widely utilized in skull base reconstruction. We present a novel technique to maintain patency of the marsupialized RCC cavity by lining it with an NSF to promote long-term drainage and re-epithelialization of the RCC cavity. METHODS Retrospective chart review of all patients who underwent surgery for symptomatic RCCs. These patients underwent endoscopic endonasal surgery between February 3, 2016, and June 12, 2018, with marsupialization followed by circumferential NSF lining. Primary outcomes include symptomatic control, surgical complications, and RCC cavity patency. RESULTS Seven patients underwent RCC marsupialization with no intraoperative cerebrospinal fluid leak, followed by circumferential lining of the marsupialized cavity with an NSF. In each case, no cyst re-accumulation or recurrent symptoms were noted, and the NSF lining provided long-term patency of the tract in all cases to a mean of 6.7 ± 10.1 months of follow-up, including one patient with sustained patency at 29 months follow-up. CONCLUSION Utilization of the NSF to "stent open" the RCC cavity following marsupialization is a safe and effective means to prevent restenosis. Advantages include sustained patency of RCC cavity for complete drainage and a dependable vascular supply. LEVEL OF EVIDENCE 4 Laryngoscope, 129:2258-2261, 2019.

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.

Abstract
Tumours involving the craniovertebral junction (CVJ) are challenging because of their local invasiveness and high recurrence rates, as well as their proximity to critical neurovascular structures and the difficulty of reconstructing the resulting skull base defect at this site. Several surgical techniques are currently available to access these lesions, including the far lateral, extreme lateral, direct lateral, transcervical, transoral and transnasal approaches. In this paper, application of the endoscopic endonasal approach (EEA) in the treatment of CVJ tumours is analysed. The indications, contraindications, preoperative workup, step-by-step surgical technique, skull base reconstruction options and postoperative management are described. The advantages and limitations of the EEA are also discussed. Finally, a systematic review of the literature is provided to elucidate the levels of evidence supporting the use of the EEA in this field. Employment of this approach to the CVJ has contributed to high success rates in achieving gross total resection of tumours and improvement in neurological symptoms. Intraoperative and postoperative complication rates are acceptable, with cerebrospinal fluid leakage being the major concern (with a 17-25% incidence). Moreover, in comparison with traditional approaches to the CVJ, the EEA provides lower rates of postoperative dysphagia and respiratory complications. Use of the EEA for treatment of CVJ tumours appears to be a rational alternative to the conventional transoral, transcranial and transcervical approaches in selected cases. Multidisciplinary teamwork including different specialists-such as medical and radiation oncologists, radiologists, otorhinolaryngologists and neurosurgeons-is strongly recommended for the purpose of offering the best treatment strategy for the patient.

Abstract
OBJECTIVE 1. To analyze the surgical outcomes in the management of petrous apex cholesterol granulomas (PACG) with a brief literature review.2. To evaluate the importance of wait-and-scan management option. STUDY DESIGN Retrospective review. SETTING Quaternary referral center for otology and skull base surgery. SUBJECTS AND METHODS Charts of 55 patients with at least 12 months of follow-up were analyzed for demographic, clinical, audiometric, and radiological features. Patients were divided into surgical group (SG) (n = 31) and wait-and-scan (n = 24) (WS) group. Surgical approach was chosen as per hearing status and PACG extension and relation to nearby neurovascular structures and included either drainage by transmastoid-infralabyrinthine approach (TM-IL)/transcanal-infracochlear approach (TC-IC) or resection by infratemporal fossa type B approach (ITF-B). The combination of ITF-B with trans-otic (TO) approach or TO approach solely was used in unserviceable hearing cases. Postoperative outcomes and complications were evaluated in SG. RESULTS Postoperative symptom relief was observed in 24 patients (77.4%). Diplopia and paresthesia recovered in each case and improvement in headache, dizziness, tinnitus, and hearing loss was observed in 87.1% cases. Serviceable hearing was preserved in 24 of 26 cases. Postoperative complication rate was 32.2% including incidences of profound hearing loss, facial nerve paresis, carotid artery injury and intraoperative CSF leaks. Revision surgery was required in 3 (9.6%) cases, after TM-IL approach. CONCLUSION Surgical drainage is preferable to more aggressive resection procedures, with the latter reserved for recurrent lesions or lesions with severe hearing loss/involvement of critical neurovascular structures. ITF-B approach provides adequate cyst and neurovascular control for resection, while avoiding brain retraction. An initial wait-and-scan approach can be used in most patients where symptoms and imaging justify so.

Abstract
BACKGROUND Inverted papillomas (IP) inserted in the frontal sinus and/or recess may be treated by using an endoscopic endonasal or an external approach. There are still few data available on this uncommon localization of IPs. OBJECTIVE To report our experience in the management of IP of the frontal drainage pathway, to describe a previously unreported specific complication of this surgery, and to discuss the optimal surgical strategy. METHODS A retrospective study of the patients at a tertiary care center between 2004 and 2014 who were operated on for an IP with an insertion in the frontal recess and/or the frontal sinus. Clinical charts were reviewed for demographics, clinical presentation, imaging findings, surgical treatment, and outcome. RESULTS Twenty-seven patients were included. Patients were operated on by using a purely endoscopic approach (Draf procedure; n = 14 [51.9%]) when the IP was inserted in the frontal recess and/or the frontal sinus infundibulum (with a nasoseptal-septoturbinal flap placed on the exposed bone in four patients), or by using a combined endoscopic and open approach (osteoplastic flap procedure; n = 13 [48.1%]) when the IP invaded the frontal sinus beyond the infundibulum. There were two recurrences (7.4%), with a mean follow-up of 40 months (range, 9-123 months). During follow-up, single or multiple iatrogenic frontal mucoceles were observed in 10 patients (37%), with a mean delay of 60 months (range, 27-89 months). These mucoceles occurred both after using endoscopic (n = 3) or combined (n = 7) approaches, and required a surgical treatment in eight patients. No postoperative mucocele was observed in the four patients who had had a septal flap. CONCLUSION In our experience, an approach based on the localization of the IP insertion provided acceptable results in terms of the local control rate (92.6%). However, the significant rate of postoperative mucoceles indicated that specific strategies (such as local flaps) still need to be developed to avoid this iatrogenic complication.

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.
