Introduction: nose is the central point of the face and vulnerable to the occurence of non-melanoma skin cancer (NMSC), impacting on appearance. The paramedian forehead flap (PMFF) is considered the best option to treat extensive nasal defects. The objective of this study is to present the experience on PMFF for nasal reconstruction in the treatment of NMSC of a cancer referral center.

Objective: MISIAN (Minimally Invasive Surgery for Treatment of Unruptured Intracranial Aneurysms) is a prospective randomized single-center clinical trial with long-term follow-up comparing different MIS techniques with standard open surgery for treatment of UIAs.
Introduction: Nonmelanoma skin cancer (NMSC) is responsible for high morbidity and mortality, resulting in a high cost to the health system. The nose is the leading region affected by this type of tumor and may need reconstruction by tissue transfer. The paramedian forehead flap (PFF) is one of the main options used, and the factors that influence the result should be studied.

- This study focuses on evaluating complications from supercharged cervical anastomosis during esophagectomy, particularly its impact on anastomotic perfusion and leakage rates.
- In the study of 80 patients, those who received supercharged anastomosis showed no anastomotic leakage compared to 10.5% in the conventional group, although this finding was not statistically significant.
- Improved blood supply to the anastomosis was confirmed with a 26.5% to 34.6% enhancement in perfusion, suggesting that supercharged techniques may better reduce complications post-surgery.
Objective: Advances in video and fiber optics since the 1990s have led to the development of several commercially available high-definition neuroendoscopes. This technological improvement, however, has been surpassed by the smartphone revolution. With the increasing integration of smartphone technology into medical care, the introduction of these high-quality computerized communication devices with built-in digital cameras offers new possibilities in neuroendoscopy.

Background: Although anterior temporal lobectomy may be a definitive surgical treatment for epileptic patients with mesial temporal sclerosis, it often results in verbal, visual, and cognitive dysfunction. Studies have consistently reported the advantages of selective procedures compared with a standard anterior temporal lobectomy, mainly in terms of neuropsychological outcomes.
Objective: To describe a new technique to perform a selective amygdalohippocampectomy (SAH) through a transpalpebral approach with endoscopic assistance.
Background: Although recent technological advances have led to successful endovascular treatment, middle cerebral artery (MCA) aneurysms are still prone to surgery. Because minimally invasive options are limited and possess several functional and cosmetic drawbacks, a transpalpebral approach is proposed as a new alternative.
Objectives: To describe and assess surgical results of the minimally invasive transpalpebral approach in patients with MCA aneurysms.
