Abstract
Meningoencephalocele is a rare congenital midline defect of cranial bone fusion characterized by herniation of the brain and meninges through the skull. In addition to the challenges of managing a major neurosurgical procedure in a pediatric patient, airway management in this group of patients requires advanced skills, and a difficult airway should be anticipated from the start. Since awake intubation is not an option in most pediatric cases with airway anatomy abnormalities and maintaining an adequate seal with a pediatric face mask is often impossible, airway management in patients with these lesions is highly challenging. We present the case of a 12-month-old girl with a postnatal diagnosis of frontoethmoidal meningoencephalocele who underwent craniotomy, followed by encephalocele resection, subsequent frontal cranioplasty, and reconstruction of the nasal bone defect. We discuss the timely adaptation of an adult face mask (size five) rotated 180º over the patient's entire face to perform adequate preoxygenation and spontaneous ventilation assistance with hand-bag ventilation after the inhalational induction of general anesthesia. After obtaining adequate depth of anesthesia, an initial video laryngoscopy with pediatric Medan® was performed. The epiglottis and vocal cords were identified, and rocuronium was administered. After complete muscle relaxation, another video laryngoscopy was performed and orotracheal intubation was successful on the first attempt. As an alternative airway, we planned orotracheal intubation using a pediatric fiberoptic bronchoscope with the aid of a laryngeal mask airway if required. As a rescue measure, we also ensured that an otolaryngologist was present in the operating room if a tracheostomy was deemed necessary. We aim to raise awareness of the importance of safe practices in anesthesia, reinforce preventive measures during careful airway examination, and plan approach strategies.

Pediatr Neurosurg 2023; 58:410-419. [PMID: 37751730 DOI: 10.1159/000534140] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/25/2023] [Accepted: 09/11/2023] [Indexed: 09/28/2023]
Abstract
INTRODUCTION The aim of the study was to investigate and identify the predictors associated with the incidence of seizures in patients with encephalocele (EC). METHODS A retrospective analysis was undertaken of patients treated for EC at a tertiary medical center in Tehran between 2010 and 2021. Data including age at presentation, gender, location, size, and content of EC, ventriculomegaly, hydrocephalus, associated anomalies, and neurodevelopmental delay (NDD) were evaluated for their prognostic value. In addition, univariate and multivariate analyses were performed to identify the correlation between independent predictors and seizure incidence. RESULTS One hundred and two cases of EC were identified. Seventy-one ECs (69.6%) were posterior ECs, while 31 (30.4%) were anterior. Neural tissue was found in 43 (42.2%) of the ECs. Thirty-three patients (32.4%) had ventriculomegaly, of which 90.9% underwent shunt placement for progressive or symptomatic hydrocephalus. Seizure was found in 26 (25.5%) patients. On univariate analysis, presence of other anomalies, postoperative infections, and NDD were associated with seizures (p < 0.05). When the anomalies were categorized into intracranial and extracranial groups in univariate analysis, none was associated with statistically significant increase in seizure (p values of 0.09 and 0.61, respectively). Although according to multivariate analysis, only the association between other associated anomalies and seizure was near significant (OR: 2.0, 95% CI: 0.95-4.2, p = 0.049). Children with NDD and postoperative infection were, respectively, 3.04 and 1.3 times more at risk to experience seizures compared to other patients. CONCLUSION We found a rate of 25.5% risk of seizure in patients with EC. This study could not find any significant predictors of seizure in children with EC. However, pediatric patients with postoperative infections including sepsis, wound infection, and NDD require more consideration to reduce the risk of seizure.

The extracranial versus intracranial approach In frontoethmoidal encephalocele corrective surgery: a meta-analysis. Neurosurg Rev 2021; 45:125-137. [PMID: 34120254 DOI: 10.1007/s10143-021-01582-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2021] [Revised: 05/01/2021] [Accepted: 06/07/2021] [Indexed: 10/21/2022]
Abstract
The debate between the extracranial and the intracranial approach for frontoethmoidal (FEE) encephalocele corrective surgery was not summarized yet. The extracranial approach is traditionally believed being inferior to the intracranial approach, but convincing evidence was missing. To provide robust evidence, we conducted a meta-analysis on the incidence of cerebrospinal fluid (CSF) leakage, its progression to infection, the reoperation to treat the leakage, and the recurrence rate between the two techniques. We performed a meta-proportion pooled analysis and meta-analysis on eligible literature following the recommendation of PRISMA guidelines. The outcome of interest was the incidence of CSF leakage, the CSF leakage that progressed into an infection, the reoperation rate to treat the leakage, and the recurrence rate. We included 28 studies comprising 1793 patients in the pooled prevalence calculations. Of the 28 studies, nine studies describing 730 patients were eligible for meta-analysis. The prevalence of CSF leakage was 8% (95% CI, 0.04-0.12) in the intracranial approach and 10% (95% CI, 0.01-0.23) in the extracranial approach The subgroup analysis of the intracranial approach showed higher CSF leakage prevalence in the frontal craniotomy approach (9%; 95% CI, 0.03-0.16) than the subfrontal osteotomy (6%; 95% CI, 0.03-0.12). Meta-analysis study revealed a significantly higher risk of CSF leakage (OR 2.82; 95% CI, 1.03-7.72), a higher reoperation rate (OR 5.38; 95% CI: 1.13 - 25.76), and the recurrence rate (RR 4.63; 95% CI, 1.51-14.20) for the extracranial approach. The event of infected CSF leakage (OR 3.69; 95% CI, 0.52-26.37) was higher in the extracranial than intracranial approach without any statistical significance. The extracranial approach was associated with a higher risk of CSF leakage, reoperation rate to treat the CSF leakage, and the recurrence rates. The infected CSF leakage between the extracranial and intracranial approaches showed no significant difference.

Abstract
INTRODUCTION Surgical correction of frontoethmoidal meningoencephalocele, although rare, is still challenging to neurosurgeons and plastic reconstructive surgeons. It is fundamental to establish reliable and safe surgical techniques. The twenty-first century has brought great advances in medical technology, and the 3D models can mimic the correct tridimensional anatomical relation of a tissue organ or body part. They allow both tactile and spatial understanding of the lesion and organ involved. The 3D printing technology allows the preparation for specific surgery ahead of time, planning the surgical approach and developing plans to deal with uncommon and high-risk intraoperative scenarios. CASE PRESENTATION The present report describes a case of frontoethmoidal encephalocele, (nasofrontal subtype) of a 19-month-old girl, whose surgical correction was planned using 3D printing modeling. CONCLUSION The 3D model allowed a detailed discussion of the aspects of the surgical approach by having tissues of different consistencies and resistances, and also predicting with millimetric precision the bilateral orbitotomy measurements. Moreover, it was a fundamental and valuable factor in the multidisciplinary preoperative discussion. This approach allowed reducing the time of surgery, accurately planning the location of the osteotomies and precontouring the osteosynthesis material. 3D models can be very helpful tools in planning complex craniofacial operative procedures.

Abstract
OBJECTIVE Although rare, frontoethmoidal meningoencephaloceles continue to pose a challenge to neurosurgeons and plastic reconstructive surgeons. Especially when faced with limited infrastructure and resources, establishing reliable and safe surgical techniques is of paramount importance. The authors present a case series in order to evaluate a previously proposed concise approach for meningoencephalocele repair, with a focus on sustainability of internationally driven surgical efforts. METHODS Between 2001 and 2016, a total of 246 patients with frontoethmoidal meningoencephaloceles were treated using a 1-stage extracranial approach by a single surgeon in the Department of Neurosurgery of the Yangon General Hospital in Yangon, Myanmar, initially assisted by European surgeons. Outcomes and complications were evaluated. RESULTS A total of 246 patients (138 male and 108 female) were treated. Their ages ranged from 75 days to 32 years (median 8 years). The duration of follow-up ranged between 4 weeks and 16 years (median 4 months). Eighteen patients (7.3%) showed signs of increased intracranial pressure postoperatively, and early CSF rhinorrhea was observed in 27 patients (11%), with 5 (2%) of them requiring operative dural repair. In 8 patients, a decompressive lumbar puncture was performed. There were 8 postoperative deaths (3.3%) due to meningitis. In 15 patients (6.1%), recurrent herniation of brain tissue was observed; this herniation led to blindness in 1 case. The remaining patients all showed good to very good aesthetic and functional results. CONCLUSIONS A minimally invasive, purely extracranial approach to frontoethmoidal meningoencephalocele repair may serve well, especially in middle- and low-income countries. This case series points out how the frequently critiqued lack of sustainability in the field of humanitarian surgical missions, as well as the often-cited missing aftercare and dependence on foreign supporters, can be circumvented by meticulous training of local surgeons.

Abstract
BACKGROUND Frontoethmoidal encephalocele is a congenital abnormality of the anterior skull base involving herniation of cranial contents through a midline skull defect. Patency of the foramen cecum, along with other multifactorial variables, contributes to the development of frontoethmoidal encephaloceles. Because of limited resources, financial constraints, and lack of surgical expertise, repair of frontoethmoidal encephaloceles is limited in developing countries. METHODS Between 2008 and 2013 an interdisciplinary team composed of neurosurgeons, craniofacial surgeons, otolaryngologists, plastic surgeons, and nursing personnel, conducted surgical mission trips to Davao City in Mindanao, Philippines. All patients underwent a combined extracranial/intracranial surgical approach, performed in tandem by a neurosurgeon and a craniofacial surgeon, to detach and remove the encephalocele. This procedure was followed by reconstruction of the craniofacial defects. RESULTS A total of 30 cases of frontoethmoidal encephalocele were repaired between 2008 and 2013 (20 male; 10 female). The average age at operation was 8.7 years, with 7 patients older than 17 years. Of the 3 subtypes, the following breakdown was observed in patients: 18 nasoethmoidal; 9 nasofrontal; and 3 naso-orbital. Several patients showed concurrent including enlarged ventricles, arachnoid cysts (both unilateral and bilateral), and gliotic changes, as well as orbit and bulbus oculi (globe) deformities. There were no operative-associated mortalities or neurologic deficits, infections, or hydrocephalus on follow-up during subsequent trips. CONCLUSIONS Despite the limitations of performing advanced surgery in a developing country, the combined interdisciplinary surgical approach has offered effective treatment to improve physical appearance and psychological well-being in afflicted patients.

Abstract
OBJECTIVE Sinonasal meningoencephalocele is a rare defect, with varying etiologies and treatment strategies. Here we present the largest published series from a single institution of patients with endoscopic repair. The primary goal is to examine rates of success with consideration to accompanying patient demographic data. The secondary goal is to report the results stratified by defect and reconstruction type. DESIGN Retrospective consecutive case series. SETTING Tertiary care academic center. SUBJECTS AND METHODS Consecutive patients with CPT codes for skull base meningoencephalocele repair between May 2000 and March 2013 were reviewed. Patients who specifically had sinonasal defects were included. RESULTS During the study period, 149 cases of sinonasal meningoencephaloceles were managed in 133 patients. Mean follow-up was 21.3 months (range, 0-116). There was a success rate of 88% for initial repair, with mean recurrence time of 8.3 months (range, 0-38), and a success rate of 93.8% for initial recurrence surgery, with 99.3% of ultimate successful repair. All cases were repaired endoscopically. Recurrence rate was not significantly related to location of defect (P = .682), size of defect (P = .434), particular reconstruction technique (P = .163), or etiology (trauma, P = .070). Overall complication rate was 11.3%. CONCLUSION Endoscopic sinonasal meningoencephalocele repair has excellent long-term results and may be considered as a primary approach. Surgeon comfort with a particular technique should be the most important factor used to guide choice of reconstruction.

Abstract
INTRODUCTION Encephaloceles are considered by most to be a type of neural tube defect characterized by a herniation of the brain and meninges through structural weaknesses in the bony structures of the skull. DISCUSSION Many different types of encephaloceles have been classified according to the location of the bony defect. Basal and frontoethmoidal encephaloceles constitute a nasal subclass of encephaloceles, which are herniations from the skull base and ethmoid bone, respectively. Basal encephaloceles are usually occult and can herniate into nasal structures causing obstruction. Frontoethmoidal encephaloceles usually present as a protrusion that is visible at birth and enlarges during crying. Both of these entities are rare with an incidence ranging from 1 in 5,000 to 1 in 40,000 live births around the world with the majority of cases localized in Southeast Asia. CONCLUSION Although cases have been recorded since the sixteenth century, there is still a scarcity of knowledge on the exact causes and factors associated with the development of the disease. Many studies have determined these to be caused by a combination of genetic and environmental factors. Most cases are non-life-threatening and the preferred method of treatment is surgical removal after diagnosis is confirmed with computerized tomography or magnetic resonance imaging. Prognosis is generally positive, especially in the subset of patients with frontoethmoidal encephaloceles.
