AI Article Synopsis
- Computer-aided surgery (CAS) systems enhance surgical procedures by combining endoscopic visuals with preoperative imaging, but lack real-time updates on surgical changes.
- A case study of a 53-year-old male with a complex sinus condition illustrates the successful use of the xCAT intraoperative mobile CT scanner during revision endoscopic frontal sinus surgery.
- The xCAT scanner offers real-time imaging updates, aiding in precise surgical navigation and improving outcomes in complicated cases, demonstrating its potential value in endoscopic sinus surgery.
Article Abstract
Introduction: Computer-aided surgery (CAS) systems integrate endoscopic visualization with real-time localization based on preoperative imaging. One short-coming of the current systems is the lack of real-time, radiographic assessment of surgical changes. We describe the potential applications of xCAT, a new intraoperative mobile volume CT scanner and its utility in providing surgical navigation updates in the operating room.
Methods: A case report is presented describing how intraoperative CT updates were used in a complicated, revision endoscopic frontal sinus surgery.
Results: A 53-year-old male with Samter's triad and a history of multiple previous endoscopic sinus surgeries presented with recurrent, symptomatic nasal polyposis and right-sided frontal headaches. Preoperative CT scans showed a large type III frontal recess cell obstructing the frontal sinus. He underwent revision endoscopic surgery with the use of CAS and the xCAT intraoperative CT scanner. Use of the intraoperative CT scanner to update preoperative images was extremely helpful in the endoscopic dissection of the frontal recess cell and in assessing completeness of dissection along the anterior skull base.
Conclusion: The xCAT intraoperative mobile volume CT scanner shows promise in providing real-time updates to surgical navigation. This may prove to be a valuable tool in endoscopic sinus surgery, especially in complex revision and frontal sinus cases.

Objective: To investigate the incidence and etiology of maxillofacial trauma (MFT) and its association with traumatic brain injury (TBI).
Background: Anecdotal evidence suggests that there is an association between MFT and TBI and that higher incidences of TBI are associated with frontal bone and mid-facial fractures. Despite the large volume of maxillofacial facial fractures treated in the authors' unit, no study has been undertaken to establish the relationship between TBI and maxillofacial fractures.

Introduction: Unilateral sphenoid sinus opacification on computed tomography is caused by a variety of pathologies including inflammatory and infectious sinusitis, benign and malignant tumors, and encephaloceles. The purpose of this study was to report craniofacial pain locations and outcomes in inflammatory unilateral sphenoid sinusitis (USS) patients who underwent endoscopic sinus surgery (ESS).
Methods: A multi-institutional retrospective cohort study was conducted on all adult patients who had ESS for USS from 2015 to 2022.

Background: The ethmoid roof separates the ethmoid cells from the anterior cranial fossa. From the medial side, the roof of the ethmoid is connected to the lateral lamella of the ethmoid plate, which is the thinnest bone at the base of the skull and is most vulnerable to damage during endoscopic surgeries. The purpose of this study is to investigate the height of the lateral lamella in patients with hypoplasia/aplasia of the paranasal sinuses and deviation of the nasal septum using reconstructed multiplanar images by cone-beam computed tomography (CBCT).
