Esteem® Active Middle Ear Implant versus Conventional Hearing Aids: Long-Term Performance.

Introduction: The totally implantable active middle ear implant Esteem® may be considered an effective alternative to conventional hearing aids (cHAs) to manage moderate-to-severe forms of sensorineural hearing loss. This study aimed to provide long-term comparative data of Esteem performances with those achieved by cHA.

Methods: From a total of 46 subjects who received unilateral application of Esteem®, and were followed up over the years, ten underwent an audiological assessment that compared the outcomes with those achieved in the contralateral ear by a cHA, considering the initially symmetric auditory thresholds in both ears.

Case report: A second case of cerebral cavernous malformation after high-dose chemotherapy for medulloblastoma.

The development of cerebral cavernous malformations (CCMs) is a well-recognized sequela of irradiation to the brain in pediatric tumors, particularly in medulloblastoma, glioma, and acute lymphoblastic leukaemia. So far, only one case of cerebral cavernoma after chemotherapy with autologous hematopoietic stem cell transplantation (HSCT) has been described. We describe a case of a patient with medulloblastoma aged 18 months at the time of oncological diagnosis who was treated with high-dose chemotherapy followed by HSCT and who developed CCM two years later.

Simultaneous Robotic-Assisted Laser Thermal Ablation of Multiple Cortical Tubers for Drug-Resistant Epilepsy in a 17-Year-Old Patient with Tuberous Sclerosis Complex.

Magnetic resonance-guided laser interstitial thermal therapy (MRgLITT) is a new minimally invasive treatment for tuberous sclerosis complex (TSC)-associated epilepsy in children. This video describes a case of a 17-year-old girl with TSC-associated drug-resistant epilepsy treated with robotic-assisted MRgLITT. In our case, MRgLITT was safe and effective in simultaneous targeting of multiple epileptic tubers in 1 single procedure, leading to a marked decrease in seizure frequency.

Neuroimaging in Nonsyndromic Craniosynostosis: Key Concepts to Unlock Innovation.

Craniosynostoses (CRS) are caused by the premature fusion of one or more cranial sutures, with isolated nonsyndromic CRS accounting for most of the clinical manifestations. Such premature suture fusion impacts both skull and brain morphology and involves regions far beyond the immediate area of fusion. The combined use of different neuroimaging tools allows for an accurate depiction of the most prominent clinical-radiological features in nonsyndromic CRS but can also contribute to a deeper investigation of more subtle alterations in the underlying nervous tissue organization that may impact normal brain development.

Giant tumefactive mesencephalothalamic Virchow-Robin space with triventricular hydrocephalus: a case-based systematic literature review.

Background: The perivascular spaces of the brain are also known as Virchow-Robin spaces (VRSs). Dilated Virchow-Robin spaces in the brainstem are rare and mainly cause symptoms due to obstructive hydrocephalus, less frequently because of their size, mass effect, and impact on eloquent structures.

Case Illustration: We present a patient with giant tumefactive VRS with hydrocephalus and neurological symptoms who was treated with endoscopic third ventriculostomy (ETV) followed by microscopic cyst fenestration.

Biobank for craniosynostosis and faciocraniosynostosis, rare pediatric congenital craniofacial disorders: a study protocol.

Purpose: Craniosynostosis (CRS) is a rare congenital cranial malformation in which 1 or more cranial or facial sutures are fused in utero or rapidly fused in early infancy. The cranial sutures separate the skull bone plates and enable rapid growth of the skull in the first 2 years of life, in which growth is largely dictated by growth of the brain. CRS is a rare disease that occurs in 1 in 2100 to 1 in 2500 births and may be either nonsyndromic (also referred to as isolated) or syndromic.

SMAS flap for extracapsular dissection of parotid gland tumors: is it necessary?

Objective: The aim of this retrospective article is to evaluate postoperative outcomes after extracapsular dissection for small benign superficial parotid neoplasms (<3 cm) in patients who received Superficial Musculoaponeurotic System (SMAS) flap and in patients who did not receive it.

Methods: Two groups were created and statistically compared regarding Frey's syndrome and aesthetic satisfaction by data collected through the POI-8 validated questionnaire and through an aesthetic satisfaction scale ranging from 1 to 10. The difference between these two groups was the utilization of SMAS flap.

Low-grade epilepsy-associated tumors: Epilepsy outcome and antiseizure medication discontinuation after lesionectomies as first-line surgical approach in pediatric population.

Objective: This study aimed to evaluate epilepsy outcome and antiseizure medication (ASM) discontinuation after lesionectomies as first surgical approach in pediatric population diagnosed with low-grade epilepsy-associated neuroepithelial tumors (LEATs).

Methods: We conducted a retrospective study. Thirty-six consecutive patients with histological diagnoses of LEATs who underwent surgery between 2018 and 2021 at our institution were included.

Jugular foramen stenosis in external hydrocephalus in infants.

Objective: To measure the size of jugular foramina in infants affected by external hydrocephalus (EH) and in a control group, to support the hypothesis that a jugular foramen (JF) stenosis may determine dural venous sinus alterations and increased venous outflow resistance as main pathophysiological factor.

Methods: Minimum, maximum, and mean values of JF areas were measured in a series of phase-contrast magnetic resonance venous angiography (angio MRV PCA3D) performed on 81 infants affected by EH. Results were compared with a group of 54 controls.

Targeting Group 3 Medulloblastoma by the Anti-PRUNE-1 and Anti-LSD1/KDM1A Epigenetic Molecules.

Medulloblastoma (MB) is a highly malignant childhood brain tumor. Group 3 MB (Gr3 MB) is considered to have the most metastatic potential, and tailored therapies for Gr3 MB are currently lacking. Gr3 MB is driven by PRUNE-1 amplification or overexpression.

Localization of the Vertical Part of the Facial Nerve in the High-Resolution Computed Tomography During Pediatric Cochlear Implantation.

Background: This study proposed a classification of the vertical portion of the facial nerve (VPFN) location, incorporating the previous classifications regarding the posterior-to-anterior and medial-to-lateral dimensions. We also evaluated the implication of this proposed classification on the round window visibility during pediatric cochlear implantation (CI).

Methods: It was a retrospective multicenter observational cohort study.

Methods: A prospective study was held between January and June 2022.

Assessment of the ability of the radiological incudo-stapedial angle to predict the stapedotomy technique type: a prospective case-series study.

Purpose: This study aimed to propose a radiological classification of the incudo-stapedial angle by preoperative high-resolution computed tomography (HRCT) images and to highlight its importance for predicting the use of reversal-steps stapedotomy (RSS) rather than the traditional non-reversal technique.

Methods: We included 83 candidates for stapedotomy operation. Two physicians measured the radiological incudo-stapedial joint angle in the preoperative HRCT.

Fully automated measurement of intracranial CSF and brain parenchyma volumes in pediatric hydrocephalus by segmentation of clinical MRI studies.

Background: Brain parenchyma (BP) and intracranial cerebrospinal fluid (iCSF) volumes measured by fully automated segmentation of clinical brain MRI studies may be useful for the diagnosis and follow-up of pediatric hydrocephalus. However, previously published segmentation techniques either rely on dedicated sequences, not routinely used in clinical practice, or on spatial normalization, which has limited accuracy when severe brain distortions, such as in hydrocephalic patients, are present.

Purpose: We developed a fully automated method to measure BP and iCSF volumes from clinical brain MRI studies of pediatric hydrocephalus patients, exploiting the complementary information contained in T2- and T1-weighted images commonly used in clinical practice.
