The STA is adequate for removal of CSR and ACF tumors under proper selection of patients. It provides an adequate view of anatomical structures and enables successful tumor resection through a less traumatic access.
In our recent study, the attempt to classify neurosurgical operative reports into routinely used expert-derived classes exhibited an F-score not exceeding 0.74. This study aimed to test how improving the classifier (target variable) affected the short text classification with deep learning on real-world data. We redesigned the target variable based on three strict principles when applicable: pathology, localization, and manipulation type. The deep learning significantly improved with the best result of operative report classification into 13 classes (accuracy = 0.995, F1 = 0.990). Reasonable text classification with machine learning should be a two-way process: the model performance must be ensured by the unambiguous textual representation reflected in corresponding target variables. At the same time, the validity of human-generated codification can be inspected via machine learning.
Introduction To determine safety and efficacy of the supraorbital eyebrow approach (SEA) in clipping of ruptured and unruptured aneurysms in comparison with the pterional approach (PA).Methods A total of 229 patients who underwent surgical clipping of aneurysm from 2013–2022 and met inclusion criteria were recruited in the study. Study group of 67 patients treated via the SEA and comparison group of 162 patients treated via the PA were formed. Then, study groups of 66 patients in each with equal incoming factors were analyzed using propensity score technique. Parameters of safety and efficacy were then retrospectively compared.Results Successful clipping was achieved in all cases of both groups. There were no patients in the SEA group who required conversion to the standard craniotomy. There were no procedure-related deaths in this series. No patient experienced early or late rebleeding in either group. Mean blood loss volume in the SEA group was lower than in the PA group by approximately 77.5ml (P < .001). There were favorable differences in the SEA group regarding postoperative neurological deficit (p = .016), postoperative epileptic seizures rate (p = .013) ischemic and hemorrhagic complications (p = .028 and .0009 respectively) and outcomes (p < .001). Patients’ satisfaction of cosmetic result measured by visual analogue scale were rated highly in both groups (p = .081).Conclusion For patients where SEA provides adequate exposure, the SEA provides safety and cosmetic outcomes that are not inferior to the PA.
The paper describes the results of clinical testing of an apparatus for dosed traction of brachial plexus trunks. It is shown that in the presence of a 5 cm diastasis, it is possible to connect the nerve fragments and perform neurorhaphy without tension by bringing the shoulder to the head and bring the shoulder to the physiological position two and a half months after the reconstructive surgery.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
