Background: Median and paramedian craniofacial clefts are associated with hypertelorism, anterior encephalocele, positional abnormalities of the maxilla, and nasal deformity. Cleft lip and palate, eyelid coloboma, and widow's peak are frequently present.
Methods: The authors collected data from 30 patients (mean age, 5.8 years; range, 4 months to 18 years) operated between 1986 and 2017 with median or paramedian craniofacial clefts of differing degrees of severity. Malformations of the different anatomic units and their surgical treatment were assessed, as well as complication rates.
Results: All patients presented nasal malformations and either telecanthus (n = 16) or hypertelorism (n = 14). Most patients (n = 23) had anterior encephalocele. All patients underwent nasal corrections, and most of them had medial canthopexy (n = 24). Excision of encephalocele was associated with fronto-orbital remodeling. Medialization of the orbits was performed in 11 patients, mainly by box shift (n = 9). Patients from outside Switzerland (n = 23) were operated at an older age than those in the native patient group. Because of staged reconstruction, 13 patients had more than one operation. Surgical complications included three infections and one expander exposition. One patient had bone resorption of a frontal bone flap. Nasal correction needed more than one procedure in 5 patients, and medial canthopexy had to be repeated in 7 patients. Esthetic results were satisfactory, permitting social integration.
Conclusion: Median and paramedian craniofacial clefts need adapted and carefully planned corrections respecting the growth of anatomic units. The quality of the medial canthal and nasal reconstruction is to a large extent responsible for the overall result.

Feasibility of robotic posterior fossa skull base surgery.
Neurosurg Focus
December 2024
1Department of Neurosurgery, Stanford University School of Medicine, Palo Alto, California.
Objective: Despite its potential advantages, robotic surgery has yet to be applied to skull base procedures. Complex anatomy and restricted access have limited the development of robotic skull base surgery. The authors' aim was to conduct a feasibility study of robotic surgery for posterior fossa skull base lesions.

Purpose: The described evolution in prenatal and postnatal periods appears to support the hypothesis that the torcular pseudomass (TP) is probably a physiological, highly frequent and transient developmental finding. Neverthless, it remains to be determined whether TP has any relation with the final anatomy of the adjacent venous sinuses or any anatomic variants. We aimed to explore the relation of the TP with the adjacent dural venous anatomy/anatomic variants in the prenatal period, using MR angiography (2D TOF MRA).

Article Synopsis
- - Biphenotypic sinonasal sarcoma is a rare, low-grade tumor found in the sinonasal tract, known for its aggressive growth and tendency to spread to surrounding areas like the orbit and skull base.
- - A comprehensive study reviewed 31 cases, highlighting that it primarily affects middle-aged women, with surgery being the main treatment method, resulting in a gross total resection in two-thirds of the patients.
- - The endoscopic endonasal approach was the most common surgical method, with a local recurrence rate of 19.3% and a low mortality rate, indicating that effective management of the tumor primarily relies on surgery.

October 2024
Department of Neurology, State Key Laboratory of Complex Severe and Rare Diseases, Peking Union Medical College Hospital, Peking Union Medical College and Chinese Academy of Medical Sciences, Beijing, China (S. Li, L.Z., Y.Z., J.N., B.P.).
Article Synopsis
- The BAD-study was a comprehensive analysis of branch atheromatous disease (BAD)-related strokes in 476 patients across 20 hospitals in China, focusing on demographic, clinical, and therapeutic aspects.
- The study found that the majority of participants were middle-aged and male, with a higher occurrence of strokes linked to the lenticulostriate artery; 86.5% of patients had good outcomes by 90 days, despite 14.7% experiencing early neurological deterioration.
- Key predictors of poor outcomes included higher stroke severity at admission and early deterioration, while extracranial artery stenosis was associated with better outcomes.
