Purpose: To investigate the applicability of piezosurgery for cervical ventral slot (CVS), comparing it with the conventional technique of using high-speed burs for bone wear.
Methods: Thirty rabbits (Oryctolagus cuniculus) were divided into two treatment groups (T1 and T2) corresponding to CVS between C3-C4. In T1, the surgery was performed with piezoelectric apparatus, and in T2 with high-speed burs. The evaluated parameters were: duration of each stage of surgery, temperature variations during CVS, visibility of the surgical field, intra and postoperative complications, and anesthetic monitoring. At 14, 28, and 56 postoperative days, five animals from each treatment group were submitted for histopathological study of the surgical site.
Results: Compared with T2, T1 had more precise bone cut, and better visibility of the operative field, although it required longer total surgical time (p = 0.02) and triggered a greater number of intraoperative complications (p < 0.01), microscopic lesions in the spinal cord (p < 0.05), and transient neurological deficits in the postoperatively (p < 0.05).
Conclusions: It is necessary to perform surgical planning and have several tips of the piezoelectric instrument available for the safe use of the piezoelectric device in neurosurgery.

Background: The transoral transpharyngeal odontoidectomy, followed by occipitocervical fixation, have traditionally been a recognized method for ameliorating ventral compression at the craniovertebral junction (CVJ), despite its associated comorbidities. As an alternative, the endoscopic endonasal odontoid resection is a viable approach for various CVJ abnromalities that preserve the oropharynx and leads to fewer procedure-related complications(1-4). We present our case to detail the technical nuances of the procedure and its advantages over other techniques.

Introduction And Importance: Type 1 gallbladder perforation (GBP) in the free abdominal cavity causes pan-peritonitis, which is both rare and difficult to diagnose.
Case Presentation: An 80-year-old man presented to our hospital with acute left upper abdominal pain. Twenty days prior to presentation, he had been admitted for 12 days with coronavirus disease 2019 (COVID-19).

Background: Spinal meningiomas (SMs) are common benign tumors that are typically treated with surgical resection. The choice of surgical approach may vary depending on the location of dural attachment of the SM, with a posterior approach being the traditional preference. However, there is limited research available on the impact of dural attachment location on outcomes following posterior approach for SM resection.

A cervical rib is the cause of ∼5% of thoracic outlet syndromes (TOS). We report the case of a patient with arterial TOS due to the presence of a cervical rib, managed by combined thoracoscopic and supraclavicular approach. An 18-year-old female patient presented with symptoms of arterial TOS.

Background: Previous computed tomography studies have reported that the superior mesenteric artery is often located ventrally to the superior mesenteric vein; however, the precise location of the peripheral jejunal arteriovenous system is unknown. This study investigated the arteriovenous positioning of the free jejunal flaps during reconstructive surgery.
Methods: This retrospective cohort study included 78 patients who underwent free jejunal flap reconstruction between June 2021 and May 2023.
