Path Tracing vs. Volume Rendering Technique in Post-Surgical Assessment of Bone Flap in Oncologic Head and Neck Reconstructive Surgery: A Preliminary Study

This study aims to compare a relatively novel three-dimensional rendering called Path Tracing (PT) to the Volume Rendering technique (VR) in the post-surgical assessment of head and neck oncologic surgery followed by bone flap reconstruction. This retrospective study included 39 oncologic patients who underwent head and neck surgery with free bone flap reconstructions. All exams were acquired using a 64 Multi-Detector CT (MDCT). PT and VR images were created on a dedicated workstation. Five readers, with different expertise in bone flap reconstructive surgery, independently reviewed the images (two radiologists, one head and neck surgeon and two otorhinolaryngologists, respectively). Every observer evaluated the images according to a 5-point Likert scale. The parameters assessed were image quality, anatomical accuracy, bone flap evaluation, and metal artefact. Mean and median values for all the parameters across the observer were calculated. The scores of both reconstruction methods were compared using a Wilcoxon matched-pairs signed rank test. Inter-reader agreement was calculated using Spearman’s rank correlation coefficient. PT was considered significantly superior to VR 3D reconstructions by all readers (p < 0.05). Inter-reader agreement was moderate to strong across four out of five readers. The agreement was stronger with PT images compared to VR images. In conclusion, PT reconstructions are significantly better than VR ones. Although they did not modify patient outcomes, they may improve the post-surgical evaluation of bone-free flap reconstructions following major head and neck surgery.

Introduction: The closed reduction of a displaced nasal fracture is a preferred method in oral and maxillofacial surgery. This prospective study was conducted to evaluate the treatment outcome following closed reduction of nasal bone fractures. Materials and methods: A total of 20 patients with nasal bone fracture who underwent closed reduction were included in the study. The cases were operated under local or general anesthesia. The outcome of treatment was evaluated pre-and postoperatively through systematic follow-ups. Clinical assessment was done to evaluate functional (airway patency, nasal obstruction, crepitus) as well as esthetic parameters (facial symmetry, swelling, and nasal deviation). Functional and esthetic satisfaction of patients was assessed using visual analog scale (VAS) pre-and post-operatively. Results: It was observed that there was significant improvement in both functional and esthetic parameters following closed reduction of nasal fractures. Conclusion: The present study suggested that closed reduction of nasal bone fracture is very effective in the management of nasal bone fractures. However, further studies with larger sample size in different clinical situations should be considered to confirm the efficacy of the same. Clinical significance: Closed reduction can be a viable and more conservative alternative in management of nasal fractures.

“…e computed tomography (CT) postprocessing imaging technique is one of the several computer-assisted technologies that have been widely used in surgical procedures and in preoperative planning or postoperative assessment [8][9][10]. Virtual reality (VR) represents a contemporary standard three-dimensional (3D) image postprocessing technique, and it is mainly used to visualize complex anatomical information and clear spatial relationships between and among different tissues [11,12]. erefore, during surgery, it can facilitate recognition of the optic canal and internal carotid.…”

The endoscopic transethmoidal approach is favored for the lack of external scars, a wide field of view, and rapid recovery time. But the effect of iatrogenic trauma should not be ignored due to the removal of the uncinate process and anterior and posterior ethmoidal sinus. Anatomically, the optic nerve is close to the sphenoid sinus and Onodi cell. In order to preserve the uncinate process and ethmoidal sinus, we perform endoscopic transsphenoidal optic canal decompression (ETOCD), which is less invasive. However, the anatomy of sphenoid sinus is quite variable, and the anatomical landmarks are rare. Therefore, identifying the position of optic canal is particularly important during surgery. To solve this, we use a postprocessing technique to identify the position of the optic nerve and internal carotid artery on the sphenoid sinus wall. Our results find that VA in 13 patients improved, with a total improve rate of 59.1%. No serious complications were found. We also found that the length of optic canal is different and the medial wall of the optic canal was the longest (p<0.05). The middle section of the optic canal is the narrowest, which was significantly different from cranial mouth and orbital mouth (p<0.05). We assumed that decompression may not require removal of all medial wall. If we remove the length of the shortest wall on the medial wall of the optic canal, the compression may be relieved. Thus, ETOCD was a feasible, safe, effective, and less-invasive approach for patients with TON. The CT postprocessing imaging facilitated recognition of the optic canal during surgery. The decompression length of the medial wall may not need to be completely removed, especially near the cranial mouth.
