The approaches for treating brainstem CMs are retrosigmoid, far lateral, midline suboccipital with or without telovelar, orbitozygomatic, and supracerebellar-infratentorial. Pontine and medullary CMs are approached via retrosigmoid, far lateral, and suboccipital craniotomies, with or without the telovelar approach.  Materials and Methods: The telovelar approach is the standard approach used for pontine brain-stem CMs. Patients with brainstem CMs treated using the telovelar approach were enrolled from three institutions.  Results: All three patients had no further neurological deficits after surgery.  Conclusions: The surgical results suggest that the telovelar approach for pons and pontomedul-lary junction brainstem CMs is safe and effective.","PeriodicalId":49515,"journal":{"name":"Skull Base-An Interdisciplinary Approach","volume":"158 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135929076","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many studies have been introducing surgical methods to prevent CSF leakage. Technique applying dural substitutes are being studied for its efficacy for preventing CSF leakage. We introduce four layer onlay stacking repair (FLOSR), effective dural closing technique for preventing CSF leak-age, while avoiding application of foreign material intradural space. Materials and Methods: Retrospective analysis of patients undergone microvascular decompres-sion (MVD) surgery for hemifacial spasm (HFS) and trigeminal neuralgia (TN) by a single surgeon in single center between September 2020 and September 2022 was done. MVD was done by retro-mastoid suboccipital approach. Number of patients who had CSF leakage, symptoms occurred by CSF leakage and treatment done for the patients were collected. Results: In this study, 355 patients underwent MVD for HFS and TN and 4 were excluded. Three patients of selected 351 patients who underwent MVD for HFS were suspected for CSF leakage which counts for approximately 0.9% of patients. All patients suspected for CSF leakage underwent MVD for HFS (3 of 3, 100%). Continuous lumbar drainage of 180-240 cc per day for 5 days was done and every patient had symptom improvement. Conclusions: FLOSR provided an effective method intra-operatively in preventing and lowering risk of severe CSF leakage after craniotomy by RMSOC (retromastoid suboccipital craniotomy) ap-proach without the risk of placing foreign materials inside dura.","PeriodicalId":49515,"journal":{"name":"Skull Base-An Interdisciplinary Approach","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135929077","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We intend to discuss strategies that may improve clinical outcomes in the surgical treatment of vestibular schwan-noma in low-volume medical centers and the correlation between the case volume of medical center and clinical outcomes. Materials and Methods: From January 2018 to December 2022, 13 patients (5 males and 8 fe-males; median age, 66 years) underwent surgery for vestibular schwannoma. The surgeries were performed by a single surgeon who initiated the clinical practice. The median length of tumors was 35 mm (range, 13-55 mm). Results: Among 13 patients, 10 patients (76.9%) underwent retromastoid suboccipital craniotomy, 3 patients (23.1%) underwent translabyrinthine approach, 4 patients (30.8%) underwent subtotal resection, 6 patients (46.2%) underwent near-total resection, and 3 patients (23.1%) underwent gross total resection. The facial nerve preservation rate was 84.6% (n = 11). Hearing preservation rate was 30.7% (n = 4). Conclusions: The surgical outcomes of vestibular schwannoma are not directly influenced by the volume of the medical institution. Instead, they are dependent on factors such as proper surgical planning, appropriate selection of surgical approaches and using intraoperative monitoring.","PeriodicalId":49515,"journal":{"name":"Skull Base-An Interdisciplinary Approach","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135929986","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several therapeutic strategies have been performed depending on tumor characteristics and the surgeon’s experience during the last decades, but it is still difficult to achieve the gross total resection with good clinical outcome. Here, we present our clinical experience with giant pituitary adenomas (PAs) focusing on factors related to surgical outcome. Materials and Methods: A total of 26 patients with giant PAs were collected. All clinical data, including preoperative symptom, visual and hormonal function, operation record, and radiologic imaging, were reviewed. Statistical analysis was used to identify the factors related with the extent of resection. Results: The median age of patients was 53 years, and all patients showed impaired vision. Endo-scopic transsphenoidal surgery, staged operation, and open craniotomy were performed in 19, 5, and 2 patients, respectively. Fifteen patients received gross total resection, 14 patients received subtotal resection and 1 patient received partial resection. Postoperatively, visual function was improved in 14 patients, not changed in 6, and deteriorated in 4. Gross total resection was significantly related with the tumor size (45 mm), Knosp grade, ICA (internal carotid artery) encasement, and middle cranial fossa extension in the statistical analysis. Conclusions: Despite of the limited experience for giant PAs, it still hard to achieve the gross total resection and good clinical outcome. We recommend identifying the tumor characteristics that make it difficult to complete total resection before surgery and consider other strategies, such as staged op-eration or adjuvant radiotherapy.","PeriodicalId":49515,"journal":{"name":"Skull Base-An Interdisciplinary Approach","volume":"194 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135928926","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to compare olfactory function in regard of partial resection status of middle turbinate (MT) and analyze the amount of resection in images. Materials and Methods: This study retrospectively reviewed 46 patients who had undergone endoscopic TSA due to pituitary adenoma or Rathke’s cleft cyst from 2015 to 2019. MT preserva-tion (MTP) group was defined as the group of patients whose MTs were preserved. MT resection (MTR) group was defined as the group of patients whose MTs were partially resected unilaterally or bilaterally. Olfactory function was compared with pre- and postoperative 3-month Korean version of sniffing sticks test-II which was composed of threshold, discrimination, identification (TDI) scores each making 16 with correct answers. Pre- and postoperative images including paranasal computed tomography and sellar magnetic resonance imaging were analyzed using Picture Archiving and Communication System. Results: There were 41 pituitary adenomas and 5 Rathke’s cleft cysts. Male patients were 39.1% (n = 18) and mean age was 42.6. About 1/3 (31%) of MT was resected in MTR group (n = 13), which had the effect of increasing the cross-sectional area of the nasal cavity by 19%. Post-septectomy area was 6% of total septum. Preoperative TDI score was 27.34 and postoperative TDI score was 25.42. There were no significant differences of olfactory score in total, MTR and MTP groups 3 months after endoscopic TSA. Conclusions: Resection of lower third of MT may produce low morbidity in respect of olfactory function after endoscopic TSA.","PeriodicalId":49515,"journal":{"name":"Skull Base-An Interdisciplinary Approach","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135929068","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
