Background: Schwannomas, benign tumors arising from neurolemmocytes, are the most common type of peripheral nerve tumors. Extracranial schwannomas are most often found in the parapharyngeal space, commonly involving the vagus nerve to cervical sympathetic trunk. Vagal schwannomas present several unique clinical and therapeutic challenges. Methods: A comprehensive literature review was conducted on 197 articles reporting 235 cases of cervical vagal schwannomas. Presenting symptoms, treatment approach, and postoperative outcomes were recorded and analyzed. Results: Vagal schwannomas commonly present as asymptomatic neck masses. When they become symptomatic, surgical resection is the standard of care. Gross total resection is associated with higher postoperative morbidity compared to subtotal resection. Initial reports using intraoperative nerve monitoring have shown improved nerve preservation. Recurrence rates are low. Conclusion: The combination of intermittent nerve mapping with novel continuous vagal nerve monitoring techniques may reduce postoperative morbidity and could represent the future standard of care for vagal schwannoma treatment.

Objectives/Hypothesis: The primary objective of this study was to assess the safety of parathyroidectomy during pregnancy as treatment for hyperparathyroidism (HPTH) in comparison to nonsurgical management plans. Secondary outcomes involved analyzing the safety of surgery in the third trimester and the benefit of operating on asymptomatic pregnant patients.Study Design: Systematic review. Methods: PRISMA-guided systematic review of all cases of primary hyperparathyroidism during pregnancy published in peer-reviewed English journals on PubMed/MEDLINE, EMBASE, and SCOPUS from 1980 to 2020.Results: A total of 75 manuscripts were included in this review describing 382 cases of gestational hyperparathyroidism. The median maternal age was 31 years. Overall, 108 cases (28.3%) underwent parathyroidectomy during pregnancy while 274 cases (71.7%) were treated nonsurgically. The majority of surgeries took place during the second trimester (67.6%). Complications and/or deaths were less likely to occur after surgery in the second trimester (4.48%) as compared to surgery in the third trimester (21.1%). Nine surgically treated cases resulted in infant complications and/or death; however, none of these nine cases had any surgical complications. Despite these complications, the overall infant complication rate for patients who underwent surgical treatment remained lower than that of patients treated with conservative therapy (9.1% vs. 38.9%).Conclusions: This review suggests that for all pregnant patients with diagnosed HPTH, parathyroidectomy should be considered regardless of symptomatology. Our data suggest that parathyroidectomy is associated with fewer risks than more conservative treatments and results in better fetal outcomes. Surgery during the third trimester is feasible and surgery should be considered in both symptomatic and asymptomatic patients.
model reduces the prevalence of falls and injuries and improves secondary outcome measurements.The number of reported fractures decreased from before to after the intervention. This could be a result of numerous contributing factors, including medication, environmental awareness, and improvement in physical fitness. Examining adherence to medication recommendations in particular, showed that 15 individuals were identified for prescription of medication to treat osteoporosis. Sixty-seven percent fully complied with this recommendation. Individuals with osteoporosis have a greater risk and prevalence of falls resulting in fractures than those without. 8 The results of this study provide additional evidence that a multidisciplinary falls clinic was effective in reducing the number of falls, the number and severity of injuries, and the amount of medical attention needed. This study also demonstrated that reducing the number of falls is achievable with less geriatrician input than past intervention programs. Future studies using this protocol should consider having the specialist on the team follow up or stress the importance of adherence to the recommendations.
Background
Vagal schwannomas are rare, benign tumors of the head and neck. Nerve damage during surgical resection is associated with significant morbidity. A new technique of continuous intraoperative nerve monitoring (IONM) that allows for real‐time intraoperative feedback has recently been used for thyroid and cervical spine surgeries but has not previously been used in vagal schwannoma surgery.
Methods
Case series of three patients who underwent vagal schwannoma excision utilizing this novel IONM technique. The recurrent laryngeal and vagus nerves were monitored via the laryngeal adductor reflex (LAR) using an electromyographic endotracheal tube.
Results
Three patients with suspected vagal schwannomas were treated surgically using the intracapsular enucleation approach with a combination of intermittent IONM and continuous IONM of the LAR.
Conclusion
This combination of continuous and intermittent IONM can be used to preserve vagal laryngeal innervation and function and may represent the future standard of care for vagal schwannoma excision.
