Abstract
Purpose Magnification with accurate optic reproduction of the surgical field is essential in otology surgery, but current technologies are subject to specific disadvantages. This study aims to evaluate a novel 3D digital stereo viewer, the Deep Reality Viewer (DRV), in otology surgery, in comparison to both a 2D monitor and the gold standard of microscopy. Methods In this prospective clinical research study, ENT consultants and trainees evaluated visual and practical applications of the DRV. In visual assessment, participants (n = 11) viewed pre-recorded in vivo mastoid exploration displayed on a 2D monitor and the DRV screen. In practical assessment, participants (n = 9) performed otology surgical tasks on a cadaveric human head using both the microscope and DRV. Face, task-specific (TSV) and global content (GCV) outcomes were assessed using 5-point Likert scale questionnaires. Construct validity was assessed separately. Results The DRV achieved the pre-determined validation threshold of 4 for all validation parameters in both visual and practical assessment. The DRV significantly outperformed the 2D monitor in fourteen of 16 parameters. In comparison to microscopy, there was no significant difference in 13 of 16 parameters, with the DRV significantly outperforming in the remaining 3: defining anatomy (GCV), assessing middle ear anatomy (TSV) and overall TSV. Construct validity was not demonstrated for either technology. Conclusion The DRV achieved the validation threshold for all parameters, and outperformed the 2D monitor and microscopy in several parameters. This validates the DRV for performing otological procedures, and suggests that it would be a useful alternative to the gold standard of microscopy in otology surgery. Level of evidence N/A.

Abstract
AbstractBackgroundThree-dimensional endoscopes provide a stereoscopic view of the operating field, facilitating depth perception compared to two-dimensional systems, but are not yet widely accepted. Existing research addresses performance and preference, but there are no studies that quantify anatomical orientation in endoscopic ear surgery.MethodsParticipants (n = 70) were randomised in starting with either the two-dimensional or three-dimensional endoscope system to perform one of two tasks: anatomical orientation using a labelled three-dimensional printed silicone model of the middle ear, or simulated endoscopic skills. Scores and time to task completion were recorded, as well as self-reported difficulty, confidence and preference.ResultsNovice surgeons scored significantly higher in a test of anatomical orientation using three-dimensional compared to two-dimensional endoscopy (p < 0.001), with no significant difference in the speed of simulated endoscopic skills task completion. For both tasks, there was lower self-reported difficulty and increased confidence when using the three-dimensional endoscope. Participants preferred three-dimensional over two-dimensional endoscopy for both tasks.ConclusionThe findings demonstrate the superiority of three-dimensional endoscopy in anatomical orientation, specific to endoscopic ear surgery, with statistically indistinguishable performance in a skills task using a simulated trainer.

Front Oncol 2019; 9:1226. [PMID: 31824838 PMCID: PMC6883371 DOI: 10.3389/fonc.2019.01226] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2019] [Accepted: 10/28/2019] [Indexed: 11/13/2022] Open
Abstract
Background: Papillary thyroid carcinoma (PTC) is the most prevalent cancer type in the endocrine system. Metastases to parapharyngeal lymph nodes (PPLNs) are rare. Herein, we reported a case series of PTC patients with PPLN metastases operated on by using the minimally invasive video-assisted (MIVA) technique to evaluate the safety and effectiveness of this technique. Method: In this single-institutional study, six consecutive PTC patients with PPLN metastases between January 2012 and July 2018 were enrolled. All PPLNs were managed by the MIVA technique. Result: Six patients (three women and three men) who underwent surgery were enrolled in the current study. The median age of patients was 40.5 years (39-66). Five patients (83.3%) were diagnosed with primary PTC with PPLN metastases, and one patient had PTC recurrence in the PPLNs 17 years after her first PTC surgery. Surgical treatment was successful in all patients, and the median operative time and bleeding volume were 185 (100-280) min and 85 (30-120) ml, respectively. None of the patients experienced post-operative complications except for one patient who experienced dysphagia, which resolved within 3 months. During a median follow-up of 15 months (10-31), none of the patients exhibited recurrence or persistent disease. Conclusion: The MIVA transcervical approach was technically feasible and reliable, with less invasiveness for PTC patients with PPLN metastases. Future studies are needed to accumulate more experience, investigate the indications of the technique, and determine the long-term oncological safety.

[PMID: 31388194 PMCID: PMC6966778 DOI: 10.14639/0392-100x-2282] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2018] [Accepted: 09/25/2018] [Indexed: 12/21/2022]
Abstract
The aim of this paper is to describe the intra-operative findings and surgical results of the first application of 3D high-definition (HD) endoscopic support to the trans-oral surgical treatment of five patients with deep hilo-parenchymal sub-mandibular stones who underwent clinical and ultrasonographic (US) follow-up examinations at one month after the procedure. Five patients undergoing 2D-HD video-assisted transoral surgery for the same condition were used as controls. The results were classified as successful (US - demonstrated complete clearance) or unsuccessful (US - demonstrated total or partial persistence). Visual analogue scales (VAS) were used post-surgically to evaluate the sharpness and brightness of the 2D and 3D images on the screen and stereoscopic depth perception (SDP) of the 3D-HD endoscope. Successful stone removal and significant subjective improvement (lack of obstructive symptoms) was obtained in all but one of the patients in the 3D group, in whom the one-month US evaluation revealed a residual 3 mm asymptomatic hilo-parenchymal stone that was successfully treated by sialendoscopy-assisted intra-corporeal laser lithotripsy. Wharton’s duct and the lingual nerve were identified and preserved in all cases. The mean 3D-HD VAS results were brightness 7 (range 6-8), sharpness 7.8 (range 7-9) and SDP 8.2 (range 8-9); the mean 2D-HD results were brightness 7.8 (range 7-9) and sharpness 7 (range 7-8). Our findings confirm the safety and efficacy of conservative transoral surgical treatment of hilo-parenchymal sub-mandibular stones. From a surgeon’s perspective, 3D-HD guided exploration of the oral floor seems to provide a better view of Wharton’s duct and the lingual nerve, especially near the sub-mandibular parenchyma. The 3D-HD video-assisted transoral removal of deep hilo-parenchymal sub-mandibular stones can therefore be considered a useful new means of preserving the function of an obstructed salivary gland.
