We performed an endoscopic mastoidectomy through a 1 cm burr hole located over the antrum. The goals were to reach predetermined landmarks and maximize the drilling of cancellous mastoid bone.

While open mastoidectomy enabled greater extents of mastoidectomy and tegmen exposure, the endoscopic approach exposed 76% of mastoid and 69.9% of the tegmen achievable by the open approach.

The long-term outcomes and benefits of the device are still being explored. Methods: A retrospective review was conducted for 11 ABI recipients at a single institution tertiary center between November 2017 to August 2022. Patients diagnosed with NF2 undergoing resection for concurrent vestibular schwannoma (VS) were included. Pre and post audiometric assessments were reviewed. Evaluation included pure-tone audiometry and speech testing. Results: Our cohort included 11 patients with a median age of 34 years old. All patients underwent a translabyrinthine approach for implant placement with concurrent VS resection. Average tumor size of VS was 2.87 cm. Pre-operatively, 8 patients had pure tone averages (PTA) with no response at 110 dB, 2 were within mild-moderate hearing loss (25-45 dB), and one patient had a PTA of profound loss (92 dB). Post-operatively, 9 (81%) patients had improvement in PTA. In total, 7 patients reported mild side effects upon ABI activation which included dizziness (n=2), tinnitus (n=1), and abdominal and lower extremity tingling sensation (n=3). Of the 7 patients with ESP scores, 5 had a score >75%, indicating the auditory ability to detect pattern perception upon auditory stimulation through the ABI alone. Conclusions: Nine of 11 patients derived benefits from ABI placement. These findings demonstrate that ABI placement during concurrent VS resection can provide a significant hearing benefit for NF2 patients.","PeriodicalId":16513,"journal":{"name":"Journal of Neurological Surgery Part B: Skull Base","volume":"19 s1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2023-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139150266","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods A systematic review of PubMed, Embase, Scopus, Web of Science and Cochrane Library databases was performed up to May 20, 2022. We included diagnostic accuracy studies that used CE-MRI for the diagnosis of PNS in patients with head and neck cancer, using histopathology from surgical specimens as the reference standard. Potential bias and applicability of the included studies was assessed using the Quality Assessment of Diagnostic Accuracy Studies 2 (QUADUS-2) tool. Pooled joint effect sizes of sensitivity and specificity were calculated by applying bivariate random-effects meta-analysis model. Results Nine studies with 259 patients were included. The pooled sensitivity and specificity of CE-MRI for detecting PNS were 89% (95% confidence interval [CI]: 73–96) and 83% (95% CI: 73–90), respectively. Stratifying by MRI strength, 1.5 T had a higher sensitivity of 97% (95% CI: 47–100) compared with 3 T, which had a sensitivity of 83% (95% CI: 72–90).

Examining which training methods are popular and effective to optimize residency learning is necessary, especially with new training adjuncts available to the modern trainee. In this study, we survey North American Skull Base Society (NASBS) members to analyze endoscopic skull base surgery education methods. \u0000 \u0000Methods: The NASBS membership was surveyed regarding endoscopic skull base surgery teaching and feedback methods using a Likert scale via an anonymized REDCAP form over four months. \u0000 \u0000Results: With a response rate of 10.1%, we found that informal teaching methods and verbal qualitative feedback were rated significantly more effective than other teaching and feedback methods (p<0.01). When comparing the opinions of otolaryngologists and neurosurgeons, otolaryngologists were less likely to believe feedback is most effective with a shared grading scale (p<0.01). Physicians with more than ten years of experience post-training felt model-based and rubric-based teaching were used more frequently (p<0.01). Respondents indicated that standardization and use of simulation, artificial intelligence, and virtual reality should be at the forefront of educational practices used in the field in the coming 5-10 years. \u0000\u0000Conclusion: Despite the current emphasis on informal training, respondents pointed to standardization and simulation as methods of endoscopic skull base surgery education that should be used more in the future.
