Systematic review of anterior congenital cephaloceles: open vs endoscopic repair

Pediatric Congenital Anterior Skull Base Encephaloceles and Surgical Management: A Comparative Review of 22 Patients Treated With Transnasally, Transcranially, or Combined Approach With a Review of the Literature

BACKGROUND AND OBJECTIVES

Anterior basal encephaloceles are considered a rare entity and are often associated with midline cerebral abnormalities. Those with a large skull base defect and herniation of brain parenchyma in the neonate or young infant present unique challenges for surgical management.

METHODS

We analyzed the neurosurgical administrative and operative databases between 1986 and 2022 to determine clinical presentation, operative approach, and outcome of basal encephaloceles.

RESULTS

Over the 36-year period, 27 pediatric anterior basal encephaloceles were managed, of which 22 had full documentation and images allowing comprehensive review. Mean age at presentation was 5 years (SD 4.94). The majority were transethmoidal encephaloceles (59%), followed by the transsphenoidal-sphenoethmoidal type (32%). Overall, 91% were managed surgically by a transcranial, endoscopic, or combined approach. Four children required subsequent procedures, predominantly for persistent cerebrospinal fluid leak. No significant differences in proportion of patients requiring interval/revision surgery after initial conservative, endoscopic endonasal, or transcranial surgery was identified. Neither age at surgery nor size of the defect on computed tomography scan was associated with the need for revision surgery. Size of cranial defect was significantly smaller in the endoscopic group (P = .01). There was a historic tendency for younger children with larger defects to have a transcranial approach. With the addition of endoscopic skull base expertise, smaller defects in older children were more recently treated endoscopically.

CONCLUSION

Basal encephaloceles are rare and complex lesions and are optimally managed within a skull base multidisciplinary team able to provide multiple approaches. Large skull base defects with brain parenchymal involvement often require a transcranial or combined transcranial-endoscopic approach.

International Consensus Statement on Allergy and Rhinology: Sinonasal Tumors

BACKGROUND

Sinonasal neoplasms, whether benign and malignant, pose a significant challenge to clinicians and represent a model area for multidisciplinary collaboration in order to optimize patient care. The International Consensus Statement on Allergy and Rhinology: Sinonasal Tumors (ICSNT) aims to summarize the best available evidence and presents 48 thematic and histopathology-based topics spanning the field.

METHODS

In accordance with prior International Consensus Statement on Allergy and Rhinology documents, ICSNT assigned each topic as an Evidence-Based Review with Recommendations, Evidence-Based Review, and Literature Review based on the level of evidence. An international group of multidisciplinary author teams were assembled for the topic reviews using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses format, and completed sections underwent a thorough and iterative consensus-building process. The final document underwent rigorous synthesis and review prior to publication.

RESULTS

The ICSNT document consists of four major sections: general principles, benign neoplasms and lesions, malignant neoplasms, and quality of life and surveillance. It covers 48 conceptual and/or histopathology-based topics relevant to sinonasal neoplasms and masses. Topics with a high level of evidence provided specific recommendations, while other areas summarized the current state of evidence. A final section highlights research opportunities and future directions, contributing to advancing knowledge and community intervention.

CONCLUSION

As an embodiment of the multidisciplinary and collaborative model of care in sinonasal neoplasms and masses, ICSNT was designed as a comprehensive, international, and multidisciplinary collaborative endeavor. Its primary objective is to summarize the existing evidence in the field of sinonasal neoplasms and masses.

A Retrospective Study of Recurrent Bacterial Meningitis in Children: Etiology, Clinical Course, and Treatment

Objectives

Recurrent bacterial meningitis (RBM) is a rare but life-threatening disease. This study aims to analyze the clinical features, potential causes, and therapeutic outcomes of RBM in children.

Methods

This article retrospectively reviews the clinical characteristics, etiologies, and treatments in children with RBM hospitalized in Hebei children's hospital from 2012 to 2020.

Results

A total of 10 children with RBM, five males and five females, were included in this study. The age of RBM in children spans from the neonatal stage to the childhood stage. The underlying illnesses were identified and classified as cerebrospinal fluid rhinorrhea (1 case), humoral immunodeficiency with Mondini dysplasia (1 case), common cavity deformity with cerebrospinal fluid ear leakage (1 case), Mondini malformations (2 cases), incomplete cochlear separation type I with a vestibular enlargement (2 cases), local inflammation of the sphenoid bone caused by cellulitis (1 case), congenital skull base defects (1 case), and congenital dermal sinus with intraspinal abscess (1 case). 6 patients chose targeted therapy for potential reasons.

Conclusions

Congenital abnormalities or acquired injuries lead to intracranial communication with the outside world, which can quickly become a portal for bacterial invasion of the central nervous system, resulting in repeated infections.
