Chondrosarcomas are one of the major malignant neoplasms which occur at the skull base. These tumors are locally invasive. Gross total resection of chondrosarcomas is associated with longer progression-free survival rates. The patient is a 55-year-old man with a history of dysphagia, left eye dryness, hearing loss, and left-sided facial pain. Magnetic resonance imaging (MRI) showed a giant heterogeneously enhancing left-sided skull base mass within the cavernous sinus and the petrous apex with extension into the sphenoid bone, clivus, and the cerebellopontine angle, with associated displacement of the brainstem (Fig. 1). An endoscopic endonasal biopsy revealed a grade -II chondrosarcoma. The patient was then referred for surgical resection. Computed tomography (CT) scan and CT angiogram of the head and neck showed a left-sided skull base mass, partial destruction of the petrous apex, and complete or near-complete occlusion of the left internal carotid artery. Digital subtraction angiography confirmed complete occlusion of the left internal carotid artery with cortical, vertebrobasilar, and leptomeningeal collateral development. The decision was made to proceed with a left-sided transcavernous approach with possible petrous apex drilling. During surgery, minimal petrous apex drilling was necessary due to autopetrosectomy by the tumor. Endoscopy was used to assist achieving gross total resection (Fig. 2). Surgery and postoperative course were uneventful. MRI confirmed gross total resection of the tumor. The histopathology was a grade-II chondrosarcoma. The patient received proton therapy and continues to do well without recurrence at 4-year follow- up. This video demonstrates steps of the combined microsurgical skull base approaches for resection of these challenging tumors.The link to the video can be found at: https://youtu.be/WlmCP_-i57s.

Superior cerebellar artery (SCA) aneurysms are rare. The management options are not well defined. There is increasing role of endovascular treatment for all aneurysms, especially for aneurysms of the posterior circulation. However in some situations (wide base, dysmorphic features) coiling is not feasible. The surgical management of these aneurysms has its own distinct complexity and requires careful planning. The classic pterional or subtemporal approaches had its own limitation in proper visualization of the neurovascular anatomy.In this video, we describe the technical nuances of transcavernous sinus approach for microsurgical clipping SCA and A-comm aneurysms. We present the case of a 67-year-old RHF who presented with ruptured right-sided SCA aneurysm. She complained of Headache, confusion, and double vision. On physical examination, she had no focal deficits and was Hunt and Hess grade 3. A brain computed tomography (CT) scan revealed a subarachnoid hemorrhage Fisher's grade 4. A brain CT angiography (CTA) demonstrated an aneurysm at the origin of right SCA. The patient had failed attempt of endovascular coiling and she underwent microsurgical clipping.Stepwise demonstration of the approach with cadaveric anatomical dissection is illustrated. The technique presented here allows for safe clipping of the aneurysm through the cavernous sinus. The approach allows for good exposure of the aneurysm and the surrounding structures. Care is taken to visualize the perforators to avoid any devastating brain stem infarction during the clipping.The transcavernous sinus is a robust approach with good visualization of the neurovascular structures allowin g safe aneurysm clipping in this location.The link to the video can be found at: https://youtu.be/oE-HyDASiKM.

xlomafota13 shared this article with you from Inoreader

J Neurooncol. 2021 May 10. doi: 10.1007/s11060-021-03773-z. Online ahead of print.

ABSTRACT

PURPOSE: Foramen magnum meningiomas (FMMs) are a major surgical challenge, due to relevant surgical morbidity and mortality. The paper aims to review the clinical (symptomatic improvement, complication rate, length of hospital stay) and radiological outcome (completeness of resection) of microsurgical resection of FMMs, and to identify predictors of complications.

METHODS: A multi-institutional retrospective review of prospectively maintained database of FMMs included 51 patients (74.5% females) with a median tumor volume of 8.18 cm3 (range, 1.77-57.9 cm3) and median follow-up of 36 months (range, 0.30-180.0 months). Tumors were resected though suboccipital approach (58.8%) or posterior-lateral approaches (39.3%), including far-lateral, extreme lateral and transcondylar approaches.

RESULTS: Gross-total resection (GTR) was achieved in 80.4% and 98% of cases did not present tumor regrowth or recurrence. Clinical symptoms improved in 34 patients (66.7%) and worsened in 5 (9.8%). The median length of hospital stay was 5 days. Mortality was null. Postoperative complications developed in 15 patients (29.4%), with cerebrospinal fluid leak (7.8%) and lower cranial nerves deficits (7.8%) as the most frequent. Craniospinal location (p = 0.03), location anterior to the dentate ligament (DL) (p = 0.02), involvement of vertebral artery (VA) (p = 0.03) were significantly associated with complication rate. These three elements allow calculating the Foramen Magnum Meningioma Risk Score (FRMMRS), to estimate the risk of post-operative complications.

CONCLUSION: Microsurgical resection allows for high GTR rate and low rate of tumor regrowth or recurrence, despite complications in one third of the patients. The FMMRS allows classifying FMMs and estimating the risk of post-operative complications.

Skull base repair following endonasal pituitary and skull base tumour resection: a systematic review

xlomafota13 shared this article with you from Inoreader

Pituitary. 2021 May 10. doi: 10.1007/s11102-021-01145-4. Online ahead of print.

ABSTRACT

PURPOSE: Postoperative cerebrospinal fluid rhinorrhoea (CSFR) remains a frequent complication of endonasal approaches to pituitary and skull base tumours. Watertight skull base reconstruction is important in preventing CSFR. We sought to systematically review the current literature of available skull base repair techniques.

METHODS: Pubmed and Embase databases were searched for studies (2000-2020) that (a) reported on the endonasal resection of pituitary and skull base tumours, (b) focussed on skull base repair techniques and/or postoperative CSFR risk factors, and (c) included CSFR data. Roles, advantages and disadvantages of each repair method were detailed. Random-effects meta-analyses were performed where possible.

RESULTS: 193 studies were included. Repair methods were categorised based on function and anatomical level. There was absolute heterogeneity in repair methods used, with no independent studies sharing the same repair protocol. Techniques most commonly used for low CSFR risk cases were fat grafts, fascia lata grafts and synthetic grafts. For cases with higher CSFR risk, multilayer regimes were utilized with vascularized flaps, gasket sealing and lumbar drains. Lumbar drain use for high CSFR risk cases was supported by a randomised study (Oxford CEBM: Grade B recommendation), but otherwise there was limited high-level evidence. Pooled CSFR incidence by approach was 3.7% (CI 3-4.5%) for transsphenoidal, 9% (CI 7.2-11.3%) for expanded endonasal, and 5.3% (CI 3.4-7%) for studies describing both. Further meaningful meta-analyses of repair methods were not performed due to significant repair protocol heterogeneity.

CONCLUSIONS: Modern reconstructive protocols are heterogeneous and there is limited evidence to suggest the optimal repair technique after pituitary and skull base tumour resection. Further studi es are needed to guide practice.

The effect of prior radiation on the success of ventral skull base reconstruction: A systematic review and meta-analysis

xlomafota13 shared this article with you from Inoreader

Head Neck. 2021 May 11. doi: 10.1002/hed.26709. Online ahead of print.

ABSTRACT

The incidence of cerebrospinal fluid leak after ventral skull base reconstruction is a primary outcome of interest to skull base surgeons. Exposure to pre-operative radiation may put patients at an increased risk of skull base reconstructive failure. A systematic search identified studies which included patients receiving ventral skull base reconstruction in the setting of pre-operative radiation. A meta-analysis using a random effects model was conducted to estimate an odds ratio of cerebrospinal fluid (CSF) leak in patients exposed to pre-operative radiation. A meta-analysis of 13 studies demonstrated that the odds ratio of CSF leak was 1.73 (95% CI 0.98-3.05). The majority of studies (77%) used vascularized tissue grafts for reconstruction. We identified an increased incidence of CSF leak among patients undergoing ventral skull base reconstruction after prior r adiation therapy, although not of statistical significance. Skull base surgeons should exercise caution when planning reconstruction in this population.

Effects of nasal packing and transseptal suturing on swallowing after septoplasty

xlomafota13 shared this article with you from Inoreader

Eur Arch Otorhinolaryngol. 2021 May 10. doi: 10.1007/s00405-021-06854-x. Online ahead of print.

ABSTRACT

PURPOSE: This clinical trial aimed to investigate the effects of different nasal packing methods and transseptal suture technique on swallowing after septoplasty.

METHODS: This randomized prospective study consists of 180 consecutive patients with septal deviation. All the patients underwent septoplasty. All the patients were randomly assigned to three groups. In group A, transseptal sutures were used for septal stabilization. In group B, both nasal passages were packed with Merocel tampons for septal stabilization. In group C, both nasal passages were packed with Doyle silicone splints for septal stabilization. For the evaluation of swallowing, the Eating Assessment Tool (EAT-10) questionnaire and a visual analog scale (VAS) were administered to all the patients preoperatively and on the second and seventh postoperative days.

RESULTS: One hundred and twenty two of the patients (67.7%) were female and 58 of them (32.2%) were male. The mean age was 32.41 ± 12.37 years (range: 18-57 years). Both EAT-10 and VAS scores on the second postoperative day were significantly higher than the preoperative scores in all the groups (p < 0.05). The transseptal suture group had significantly lower EAT-10 and VAS scores on the second postoperative day than the Merocel packing and silicone packing groups (p < 0.05). Both EAT-10 and VAS scores on the postop 7th day significantly decreased in all groups compared to the postop second day (p < 0.05).

CONCLUSIONS: Septoplasty affects swallowing, regardless of whether a tampon is applied. Transeptal suturing has a lesser effect on swallowing than other techniques. Although silicone packing is a less invasive method, it negatively affects swallowing, similar to Merocel packing. The transseptal suture technique is more comfortable than the other techniques i n terms of swallowing function in the postoperative period.

J Oral Rehabil. 2021 May 10. doi: 10.1111/joor.13181. Online ahead of print.

ABSTRACT

BACKGROUND: Chin tuck against resistance (CTAR) exercise has been recently reported to be a new therapeutic exercise method that can help improve swallowing function in patients with dysphagia. However, due to the differences in exercise protocols, methods, and the tools used across studies of CTAR exercise, an overall systematic review of these studies is necessary.

OBJECTIVE: The present s tudy investigated the exercise protocols, methods, and tools used in various studies of CTAR exercise and summarized their findings.

METHODS: We searched for studies related to CTAR exercise using electronic databases and selected nine articles for review. The articles were categorized on the basis of four criteria: study design and quality, training protocol, outcome measures, and clinical effect.

RESULTS: Four articles reported that CTAR exercise not only helped activate the suprahyoid muscle in healthy adults, but activated the sternocleidomastoid muscle less than Shaker exercise. In addition, five articles reported that CTAR exercise was effective in improving swallowing function and oral diet stage in the pharyngeal phase, including reduction of airway aspiration in patients with dysphagia after stroke.

CONCLUSIONS: CTAR exercise more selectively activates the suprahyoid muscle and is an effective therapeutic exercise for improving swallowing function in patie nts with dysphagia. Because it is less strenuous than Shaker exercise, it requires less physical burden and effort, allowing greater compliance.
