![]() Tumors involved the skull base in 125 cases. RESULTS: 197 patients (66%) underwent surgery for supratentorial tumors, the remaining 103 (34%) for infratentorial ones. Preoperative and postoperative imaging, clinical notes and intraoperative details were collected. METHODS: We analyzed a series of 300 patients (range 1-81 years, SD☑5.2) that underwent elective cranial surgery for brain tumors, in which the craniotomy was performed using a piezoelectric device. We evaluated safety and feasibility of craniotomies using an ultrasonic device that allows the selective cut of mineralized structures, avoiding damages to the vascular, dural and parenchymal structures. OBJECTIVE: Piezoelectric surgery represents an innovative technique to perform safe and effective osteotomies, alternative to traditional bony tissue management using rotating or perforating instruments. KEYWORDS: Graves’ orbitopathy Orbital decompression diplopia piezosurgery proptosis reduction ![]() No serious adverse events were recorded in both groups.ĬONCLUSION: The application of piezosurgery in orbital decompression is more suitable than an oscillation saw due to superior cutting properties such as less damage to surrounding soft tissue or a thinner cutting grove. Duration of the surgery did not differ between the groups. Intraoperative handling of the piezosurgery device was judged superior to the oscillating saw, due to soft tissue conservation and favourable cutting properties. Proptosis reduction was 4.6 mm in the saw group (p < 0.01) and 5.3 mm in the piezo group (p < 0.01). RESULTS: We observed no significant differences in the surgical outcome between the two groups. Peri- and postoperative complications, reduction of proptosis, new onset of diplopia and improvement of visual acuity in cases of pre-operative optic nerve compression were analyzed. An oscillating saw was used in 165 cases (saw group) and piezosurgery in 153 cases (piezo group). METHODS: In a retrospective study, we analyzed balanced orbital decompressions performed on 174 patients (318 cases) with GO. This study aims to compare piezosurgery to an oscillating saw used to resect bone from the lateral orbital wall. INTRODUCTION: Different minimally invasive surgical approaches to the orbit allow individualized bone resection to reduce proptosis and decompress the optic nerve in patients with Graves' orbitopathy (GO).

The limit of operation times can be overcome by a learning curve in neurosurgery and PSP.Ĭopyright © 2019. The operative times were significantly shorter in group B (13 vs 23 minutes), though the newer PS plus (PSP) was demonstrated to significantly shorten these times compared with the traditional PS (3.5 vs 6.5 minutes for orbitotomy, 7.5 vs 9.5 minutes for hemi-craniotomy).ĬONCLUSIONS: PS is a safe and effective tool that can be specifically recommended for bone splitting and graft, laminotomy and craniotomy in cosmetically eloquent areas. PS also reduced the risk of dural tears (1 vs 7 cases in group A and B, respectively) and blood transfusion (52% vs 55.5%) but without statistical significance. A statistically significant difference in favor of group A was found about EBS (105 vs 113 ml) and late outcome (Sloan's class A 98.5% vs 91.5%). RESULTS:172 children were enrolled, 90 belonging to group A and 82 to group B. ![]() A review of the pertinent literature has been included. The following variables were analyzed: dural tears, estimated blood loss (EBS) and need of transfusion, cosmetic outcome (Sloan's score), operative times. METHODS: All consecutive craniotomies and laminotomies, performed with PS (group A) or conventional osteotomes (group B) in the 2014-2017 period, have been reviewed. The present study assesses PS in the pediatric population considering outcome and complications also in cranial and spinal procedures. In pediatric neurosurgery, the experience is limited to craniosynostosis surgery. īACKGROUND: Piezosurgery (PS) gained an increasing diffusion in neurosurgery.
