We compared two strategies for treating newborns with myeloschisis or myelomeningocele (open neural tube defect [oNTD]) and hydrocephalus. These strategies involved insertion of a ventriculo-peritoneal shunt (VPS) either synchronous with or sequential to surgical closure of the oNTD. We investigated shunt infection and cerebrospinal fluid (CSF) leakage rates and their effects on the duration of hospitalization for both treatments. The study involved 65 patients with hydrocephalus and open neural placodes which were covered with a thin pseudomembrane. Thirty-eight infants underwent an oNTD repair operation and shunting during the same surgical session (synchronous group [group 1]), and 27 infants underwent sequential procedures, in which shunt insertion was delayed until the thoracolumbar wound was partially healed (sequential group [group 2]). Group 1 had a mean duration of hospital stay of 15.5 days, significantly less than the average 28.8 days of group 2 (p < 0.05). No significant differences in CSF leakage and shunt infections occurred between the two groups (p > 0.05). The incidence of shunt infection due to CSF fistulas that developed postoperatively was higher for patients with CSF leakage as a result of oNTD at birth than for patients without CSF leakage (p < 0.05). Patients with oNTD are at significant risk of infections because of the thin pseudomembrane over the defect. In addition, newborn patients may also have a weakened immune system. Despite these disadvantages, VPS placement within a single session can be advantageous for the patient, family and physician, compared to multiple surgical procedures. It is also more cost-effective.

Department of Neurosurgery, Medical University of Warsaw, Banacha St. 1a, 02-097, Warsaw, Poland.

Background: In the early days of neurosurgery, extradural haemorrhages (EDHs) contributed to a high mortality rate after craniotomies. Almost a century ago, Walter Dandy reported dural tenting sutures as an effective way to prevent postoperative EDH. Over time, his technique gained in popularity and significance to finally become a neurosurgical standard. Read More

Gland Surg 2021 Mar;10(3):1010-1017

Department of Neurosurgery, Qilu Hospital of Shandong University, Jinan, China.

Background: Bioresorbable alloplastic implants have become desirable as a rigid buttress for reconstructing skull base defects. This study aimed to describe the use of a biodegradable plate (PolyMax RAPID) in skull base repair of endoscopic endonasal pituitary surgery and to investigate the clinical outcome and safety of this novel method.

Methods: Between January 2019 and January 2020, 22 patients with pituitary adenomas who underwent endoscopic skull base repair with a Polymax RAPID plate were included. Read More

Acta Neurochir Suppl 2021 ;131:329-333

Skull Base Unit, Department of Neurosurgery B, Neurological Hospital Pierre Wertheimer, University Hospital of Lyon, Lyon, France.

Introduction: Managing skull base cerebrospinal fluid (CSF) leaks is often challenging. Postoperative care, especially regarding postural restrictions and bedrest recommendations, is variable and continues to be based on empirical habits.

Methods: An electronic survey was submitted to French experts in skull base surgery to evaluate current practice of postoperative postural recommendations in patients treated for skull base CSF leaks. Read More

Bobby R. Alford Department of Otolaryngology-Head and Neck Surgery, Baylor College of Medicine, Houston, TX, USA.

Objectives: To report a recalcitrant spontaneous cerebrospinal fluid (CSF) fistula arising from multiple, anatomically-linked lateral skull base defects, and to review the available literature to determine optimal techniques for operative repair of congenital CSF fistulae.

Methods: A patient with recurrent episodes of otologic meningitis was found to have a patent tympanomeningeal fissure, also known as a Hyrtl's fissure, and internal auditory canal (IAC) diverticulum that communicated with the jugular bulb. A systematic review of the literature characterized all reports of spontaneous congenital perilabyrinthine CSF leaks, and all cases of Hyrtl's fissures. Read More
