Surgical Navigation Technology for Treatment of Pneumosinus Dilatans

The objective of this study is to present the use of surgical navigation in the selective removal of the anterior table of the frontal sinus in a patient with pneumosinus dilatans. A 16-year-old boy presented with progressive deformity of the forehead and left postauricular sulcus due to pneumosinus dilatans. Reconstruction of the anterior table of the frontal bone was assisted by a surgical navigation system that used data from a preoperative computed tomography scan of the head and neck to map out the boundaries of the frontal sinus. The device enabled selective resection of the anterior table without violation of the cranial cavity.

Abstract This study analyzed the outcomes of zygomatico-orbital fracture reconstruction using the real-time navigation system with intraoperative three-dimensional (3D) C-arm computed tomography (CT). Fifteen patients with zygomatico-orbital or isolated orbital/zygoma fractures were enrolled in this prospective cohort. For zygoma reduction, the displacement at five key sutures and the differences between preoperative and intraoperative CT images were compared. For orbital reconstruction, the bilateral orbital volume differences in the anterior, middle, and posterior angles over the medial transitional buttress were measured. Two patients required implant adjustment once after the intraoperative 3D C-arm assessment. On comparing the preoperative and postoperative findings for the zygoma, the average sum of displacement was 19.48 (range, 5.1–34.65) vs. ±1.96 (0–3.95) mm (P < 0.001) and the deviation index was 13.56 (10–24.35) vs. 2.44 (0.6–4.85) (P < 0.001). For the orbit, the mean preoperative to postoperative bilateral orbital volume difference was 3.93 (0.35–10.95) vs. 1.05 (0.12–3.61) mm3 (P <0.001). The mean difference in the bilateral angles at the transition buttress was significantly decreased postoperatively at the middle and posterior one-third. The surgical navigation system with the intraoperative 3D C-arm can effectively improve the accuracy of zygomatico-orbital fracture reconstruction and decrease implant adjustment times.

ABSTRACT To compare the anatomical and pathological features on computed tomography (CT) scan with intraoperative findings in cases of frontal sinus disease. This prospective study was conducted in a tertiary referral center, and a total of 30 patients who were refractory to conservative medical treatment undergoing endoscopic sinus surgery for frontal sinus disease were included in the study. Preoperative CT scans were done with axial and coronal cuts with a sagittal reconstruction to obtain a better idea about the frontal recess anatomy. The areas that were studied preoperatively on CT scan were frontal sinus pathology, pattern of sinus involvement, superior attachment of uncinate process, frontal sinus drainage pathway, agger nasi cell, frontal cell, frontal bullar cell, and supraorbital ethmoidal cell. A good correlation was obtained between the CT findings and intraoperative findings. How to cite this article Chakraborty S, Verma D, Lade H, Malik NUD.
