RESUMO
Tonsillectomy is one of the most frequent surgical procedures performed by ENT surgeons. The high-definition 3D exoscope showed to be a promising tool to substitute the operating microscope in performing microsurgical procedures. However, transoral surgery might represent an innovative application of this visualization and magnification tool. In this video, a bilateral tonsillectomy was performed entirely under exoscopic visualization by an ENT resident. The high-definition 3D exoscope allowed to conduct the procedure with higher precision, with potential benefits in terms of complications and postoperative pain. Moreover, the use of the exoscope demonstrated important benefit from the educational perspective, allowing the senior surgeon to continuously monitor the resident without interruptions and position changes. The exoscopic-assisted tonsillectomy is a valuable alternative to conventional transoral procedures, and the superiority of this technique should be further investigated in cohort studies.

BACKGROUND: The high-definition 3D exoscope is an innovative and promising tool that was recently introduced in the clinical practice. It may be used during open surgical procedures to enhance the ability to perform precise dissection of fine structures. We describe our preliminary experience with the 3D exoscope in thyroid surgery, discussing potential advantages of this system. METHODS: A high-definition 3D exoscope (3D VITOM®) mounted on the VERSACRANETM holding system (Karl Storz, Tuttlingen, Germany) was used to perform open thyroid surgery. RESULTS: The 3D exoscope was used in three patients without significant intra-operative delay or complications. Both thyroidectomy and central compartment dissection were performed. The 3D exoscope allows to perform precise dissection in the identification and preservation of the recurrent laryngeal nerve and the parathyroid glands. CONCLUSIONS: 3D exoscope-assisted thyroid surgery seems to be feasible and safe. Further studies should be encouraged to analyze potential clinical benefit in the post-operative period.

Laryngomalacia is the most frequent congenital laryngeal anomaly. Surgery is possible by means of cold knife, carbon dioxide (CO2 ) laser, microdebrider and coblation, traditionally under microscopic view. We here describe the use of the 3D-4K exoscope assisted CO2 laser supraglottoplasty in tubeless general anesthesia in spontaneous breathing in a 5 month-old patient with severe laryngomalacia. Laryngoscope, 134:1359-1362, 2024.

Objective: The development of surgical microscope-associated cameras has given rise to a new operating style embodied by hybrid microsurgical and exoscopic operative systems. These platforms utilize specialized camera systems to visualize cranial neuroanatomy at various depths. Our study aims to understand how different camera settings in a novel hybrid exoscope system influence image quality in the context of neurosurgical procedures. Methods: We built an image database using captured cadaveric dissection images obtained with a prototype version of a hybrid (microsurgical/exoscopic) operative platform. We performed comprehensive 4K-resolution image capture using 76 camera settings across three magnification levels and two working distances. Computer algorithms such as structural similarity (SSIM) and mean squared error (MSE) were used to measure image distortion across different camera settings. We utilized a Laplacian filter to compute the overall sharpness of the acquired images. Additionally, a monocular depth estimation deep learning model was used to examine the image's capability to visualize the depth of deeper structures accurately. Results: A total of 1,368 high-resolution pictures were captured. The SSIM index ranged from 0.63 to 0.85. The MSE was nearly zero for all image batches. It was determined that the exoscope could accurately detect both the sharpness and depth based on the Laplacian filter and depth maps, respectively. Our findings demonstrate that users can utilize the full range of camera settings available on the exoscope, including adjustments to aperture, color saturation, contrast, sharpness, and brilliance, without introducing significant image distortions relative to the standard mode. Conclusion: The evolution of the camera incorporated into a surgical microscope enables exoscopic visualization during cranial base surgery. Our result should encourage surgeons to take full advantage of the exoscope's extensive range of camera settings to match their personal preferences or specific clinical requirements of the surgical scenario. This places the exoscope as an invaluable asset in contemporary surgical practice, merging high-definition imaging with ergonomic design and adaptable operability.
RESUMO
Introduction: The increasing population of survivors of head and neck carcinomas is becoming more conspicuous. Consequently, the pivotal role of quality of life, particularly elucidated through the assessment of dysphagia and dysphonia, is progressively influencing the decision-making process. The current study aims to assess whether VITOM 3D could offer a comparable post-treatment quality of life to traditional approaches for patients with laryngeal cancer and oro-hypopharyngeal cancer. Methods: A case series of laryngeal cancer and oro-hypopharyngeal cancer patients treated either with an exoscopic-assisted surgical setup and with conventional treatments (transoral microsurgery and radio-chemotherapy) at the Otolaryngology Unit of IRCCS San Martino Hospital, Genoa, is presented. The post-treatment quality of life of the two cohorts were compared through the administration of the University of Washington Quality of Life Questionnaire, Voiceik Handicap Index-10, M.D. Anderson Dysphagia Inventory were administrated to both cohorts of patients. Results: In the laryngeal cancer group, a total of 79 patients were included. Of these, 50.1% underwent transoral exoscope-assisted surgery, while 49.9% underwent primary transoral microscopic-assisted surgical approach. No significant differences were observed in terms of the University of Washington Quality of Life Questionnaire and Voice Handicap Index-10 between the two subgroups. Conversely, in the oro-hypopharyngeal cancer group, 43 patients were included. Of these, 37.2% underwent primary transoral exoscope-assisted surgery, while 62.8% received (chemo)radiotherapy. No notable differences were reported in terms of the University of Washington Quality of Life Questionnaire and M.D. Anderson Dysphagia Inventory between the transoral exoscope-assisted surgery and (chemo)radiotherapy subgroups. Conclusions: Assessments of quality of life, conducted through the University of Washington Quality of Life Questionnaire questionnaire, dysphonia evaluations using the Voice Handicap Index-10, and dysphagia assessments employing the M.D. Anderson Dysphagia Inventory questionnaire, demonstrate analogous outcomes between conventional treatment modalities and transoral interventions utilizing the 3D exoscope.
RESUMO
This PRISMA-compliant systematic review aimed to investigate the use of and the most common procedures performed with the novel 3D 4K exoscope in surgical pediatric head and neck settings. METHODS: Search criteria were applied to PubMed, EMBASE and the Cochrane Review databases and included all studies published up to January 2023 reporting 3D 4K exoscope-assisted surgeries in pediatric patients. After the removal of duplicates, selection of abstracts and full-text articles, and quality assessment, we reviewed eligible articles for number of patients treated, age, surgical procedures, and outcomes. RESULTS: Among 54 potentially relevant records, 5 studies were considered eligible and included in this systematic review, with reported treatment data for 182 patients. The surgical procedures belong to the otologic field (121 cases), head and neck surgery (25 cases) and transoral surgery (36 cases). Exoscopy allowed high quality visualization of anatomical structures during cochlear implantation and during reconstruction in head and neck surgery; moreover, it improved the surgical view of surgeons, spectators and ENT students. CONCLUSIONS: The use of 3D 4K exoscopy has shown promising potential as a valuable tool in pediatric ORL-head and neck surgery; nevertheless, further validation of these encouraging outcomes is necessary through larger-scale studies specifically focused on pediatric patients.
RESUMO
OBJECTIVE: The recent introduction of 3D exoscopic surgery has engendered interesting technical improvements in head and neck surgery. The main goal of this study was to describe the application of 3D exoscopic technology on a wide range of pathologies of the neck, benign and malignant, through a minimally invasive retroauricular approach. METHODS: In the period January-December, 2019, 40 consecutive patients underwent neck surgery with a retroauricular approach, enhanced by using a 3D exoscope at the Head and Neck Oncological Unit of Candiolo Cancer Institute. RESULTS: Data regarding time to drain removal, length of hospitalisation, degree of pain experienced, need for opioid drugs during hospitalisation and after discharge, and intra-operative and post-operative complications were collected. All patients were followed for a minimum of 90 days with possible complications evaluated at each post-operative visit. Post-operative outcomes were evaluated at 3 months after surgery. CONCLUSIONS: The current study indicates that VITOM-3D-assisted retroauricular neck surgery (RANS-3D) may be an interesting approach for neck surgery. The hybrid execution of neck dissection under direct and exoscopic vision represents a valid alternative to video-assisted endoscopic- and robot-assisted techniques.

Over the past three decades, the incidence of oropharyngeal squamous cell carcinoma has increased, primarily related to the spread of human papillomavirus. Treatment has always been preferentially unimodal (surgery or radiotherapy) for early stage disease and multimodal (surgery with adjuvant therapy or concomitant chemoradiotherapy) for advanced stages. Recently, the surgical approach has gained renewed interest due to the morbidity of non-surgical treatments and also to technical innovations. We have coined the term 3Des (3D exoscope surgery) to describe the use of the 3D Vitom Exoscope System for transoral surgery of oropharyngeal cancers. During the period from June 2017 to May 2018, 10 patients with oropharyngeal cancer were treated by oropharyngeal surgery with the 3Des approach at FPO IRCCS Institute of Candiolo. The aim of the present prospective study was to evaluate the utility of 3Des for the treatment of early-stage oropharyngeal cancer. 3Des could represent a viable alternative to the operating microscope and robotic surgery thanks to its excellent ability to provide 3D visual information, depth of field, magnification, image contrast, color imaging, and low running costs. It promises great utility in the learning process, with the possibility of recording in high definition.
