“…The subjective superiority of 3D endoscopy in EES has been widely reported by both clinical and laboratory studies and is confirmed by the subjective results of the present study . The present study showed significantly better rating of depth perception, discriminatory power and the value in performing delicate procedures using the 3D HD endoscope.…”

“…This endoscope has an interpupillary distance of 1.2 mm and a dynamic focus range of 8‐80 mm. It uses “insect eye” technology—incorporating an array of microlenses integrated into 4 mm optics—to project two separate endoscopic images onto dedicated sections of the camera chip . The images were displayed on a 24‐inch HD (1920 × 1080 pixels) stereoscopic LED flat screen that offered true stereoscopic images when passive polarising glasses were worn.…”

Objectives Endoscopic imaging techniques and endoscopic endonasal surgery (EES) expertise have evolved rapidly. Only few studies have assessed the effect of three‐dimensional (3D) endoscopy on endoscopic sinus surgery (ESS). The present study aimed to objectively and subjectively assess the additional value of 3D high‐definition (HD) endoscopy in ESS. Design A randomized crossover study of endoscopic surgery performance, using five ESS tasks of varying complexity, performed on Thiel embalmed human specimens. Setting Simulated surgical environment. Participants Thirty participants, inexperienced in ESS. Main outcome measures Performance was assessed using video imaging, surgical navigation and questionnaires. Main outcome measures were as follows: efficiency (defined by time to task completion), distance covered inside the nose, average velocity towards target, accuracy (measured by error rate), and subjective assessment of endoscope characteristics. Results During ESS tasks, both efficiency and accuracy did not differ significantly between 2D HD and 3D HD endoscopy. Subjectively, imaging characteristics of the 3D HD endoscope were rated significantly better. Conclusions ESS performance of inexperienced participants was not significantly improved by the use of 3D HD endoscopy during ESS tasks, although imaging characteristics of the 3D HD endoscope were rated significantly better. Surgical field characteristics and surgical techniques are likely to influence any additional value of 3D HD endoscopy.

Background Endoscopic skull‐base surgery (ESBS) is employed in the management of diverse skull‐base pathologies. Paralleling the increased utilization of ESBS, the literature in this field has expanded rapidly. However, the rarity of these diseases, the inherent challenges of surgical studies, and the continued learning curve in ESBS have resulted in significant variability in the quality of the literature. To consolidate and critically appraise the available literature, experts in skull‐base surgery have produced the International Consensus Statement on Endoscopic Skull‐Base Surgery (ICAR:ESBS). Methods Using previously described methodology, topics spanning the breadth of ESBS were identified and assigned a literature review, evidence‐based review or evidence‐based review with recommendations format. Subsequently, each topic was written and then reviewed by skull‐base surgeons in both neurosurgery and otolaryngology. Following this iterative review process, the ICAR:ESBS document was synthesized and reviewed by all authors for consensus. Results The ICAR:ESBS document addresses the role of ESBS in primary cerebrospinal fluid (CSF) rhinorrhea, intradural tumors, benign skull‐base and orbital pathology, sinonasal malignancies, and clival lesions. Additionally, specific challenges in ESBS including endoscopic reconstruction and complication management were evaluated. Conclusion A critical review of the literature in ESBS demonstrates at least the equivalency of ESBS with alternative approaches in pathologies such as CSF rhinorrhea and pituitary adenoma as well as improved reconstructive techniques in reducing CSF leaks. Evidence‐based recommendations are limited in other pathologies and these significant knowledge gaps call upon the skull‐base community to embrace these opportunities and collaboratively address these shortcomings.

The aim of this study is to report our preliminary experiences with regard to safety and feasibility of three-dimensional (3D) endoscopic lacrimal surgeries with a recently launched latest generation 3D endoscope. A 4-mm rigid three-dimensional (3D) endoscope (TIPCAM 1S 3D ORL, Karl Storz, Tuttlingen, Germany) was used. Fifteen patients who underwent various endoscopic lacrimal procedures by a single surgeon (MJA) were included. The procedures included probing with nasolacrimal intubation, cruciate marsupialization of intranasal cysts for congenital dacryoceles, powered endoscopic dacryocystorhinostomy, post-operative stent removal with ostium granuloma excision. The implementation, visualization, optical performance, ease of tissue handling and complications were noted. Ten surgical observers filled a questionnaire to rate their experiences. Enhanced depth perception was found to be very beneficial intraoperatively. Greater anatomical delineation facilitated improved hand-eye coordination and dexterity. Intraoperative assessment and handling of tissues and surgical manoeuvring were precise and did not require the additional spatial cues that the surgeon derives from a two-dimensional image. These benefits were more appreciated in the complex cases. The setup was easy on previous endoscopic platforms and did not consume any additional time. All the surgical procedures were completed successfully without any complications. The surgical observers unanimously noted enhanced anatomical understanding and surgical learning as compared to the routine 2D planes. Operating in 3D planes enhances depth perception, dexterity and precision. Although initial results are promising, further randomized studies with head-on comparisons between 3D and 2D would help formulate specific guidelines.

The use of a three-dimensional endoscope for different skull base tumors: results of a preliminary extended endonasal surgical series

Abstract: In our experience, the 3-D endoscope represents a critical development in visualization, thus enabling improved hand-eye coordination and depth perception, which are mandatory for the management of complex intradural neurovascular structures during tumor removal surgery.
