Transoral robotic-assisted tongue base resection in pediatric obstructive sleep apnea syndrome: case presentation, clinical and technical consideration

Clinical application of robots in dentistry: A scoping review

PURPOSE

The surge in digitalization and artificial intelligence has led to the wide application of robots in various fields, but their application in dentistry started relatively late. This scoping review aimed to comprehensively explore and map the current status of the clinical application of robots in dentistry.

STUDY SELECTION

An iterative approach was used to gather as much evidence as possible from four online databases, including PubMed, the China National Knowledge Infrastructure, the Japan Science and Technology Information Aggregator, Electronic, and the Institute of Electrical and Electronics Engineers, from January 1980 to December 2022.

RESULTS

A total of 113 eligible articles were selected from the search results, and it was found that most of the robots were developed and applied in the United States (n = 56; 50%). Robots were clinically applied in oral and maxillofacial surgery, oral implantology, prosthodontics, orthodontics, endodontics, and oral medicine. The development of robots in oral and maxillofacial surgery and oral implantology is relatively fast and comprehensive. About 51% (n = 58) of the systems had reached clinical application, while 49% (n = 55) were at the pre-clinical stage. Most of these are hard robots (90%; n = 103), and their invention and development were mainly focused on university research groups with long research periods and diverse components.

CONCLUSIONS

There are still limitations and gaps between research and application in dental robots. While robotics is threatening to replace clinical decision-making, combining it with dentistry to gain maximum benefit remains a challenge for the future.

Experience in Transoral Robotic Surgery in Pediatric Subjects: A Systematic Literature Review

Pediatric transoral robotic surgery (TORS) has improved from 2007 to 2020, widening its indications and feasibility. This article aims to systematically analyze the procedures performed from the first use until the current year, observing their evolution over time. A systematic literature review was performed using PubMed, Scopus, Web of Science, and Cochrane databases between March 1, 2000, and April 1, 2020. We selected studies that were written only in English and were performed in live human subjects. About 16 studies were found with a total of 73 subjects treated, among them 41 were men and 32 were women with an average age of 6.8 ± 4.99 years. There have been four (5.47%) conversions. Both functional and benign-malignant diseases have been treated in the series. Eleven (15.06%) pre-operative tracheostomy and zero post-operative tracheostomy were performed. The bleeding data was only reported in 9 studies and was <50 ml. Only one (1.36%) intra-operative complication and 10 (12.32%) postoperative complications were reported. We consider the TORS procedures in pediatric subjects safe, feasible and with good surgical outcomes up to the laryngeal region.

Robotics in Pediatric Otolaryngology-Head and Neck Surgery and Advanced Surgical Planning

Robotic surgery has been shown to be feasible and successful in several areas of pediatric head and neck surgery. However, adoption has been limited. Robotic surgery may be better integrated into practice with advanced preoperative surgical planning and the design of new robotic platforms with instrumentation specific for the application. With continued investigations, computer-aided surgical planning techniques including three-dimensional printing, virtual reality, multiobjective cost function for optimization of approach, mirror image overlay, and flexible robotic instruments may demonstrate value and utility over current practice.

Assessment of obstructive sleep apnoea (OSA) in children: an update

OSA is a condition characterised by episodes of complete or partial obstruction of the upper airway, associated with blood-gas changes and atypical sleep patterns. Early diagnosis of OSA may reduce the occurrence of systemic complications over time, although the diagnosis of OSA is, unfortunately, often late. The aim of the work is to review the current concepts in evaluation of paediatric obstructive sleep apnoea (OSA), with an updated revision of the literature considering risk factors, clinical manifestations, and basic and advanced assessment in the paediatric population. For this narrative review, PubMed, Embase and Cinahl databases were searched for the last 10 years, according to PRISMA criteria/guidelines. Assessment of paediatric OSA remains challenging and paediatric patients should always be carefully evaluated; polysomnography is the gold standard for diagnosis of paediatric OSA.

Alternative Applications of Trans-Oral Robotic Surgery (TORS): A Systematic Review

Background: The role of robotic surgery in the field of oncology has been widely described, in particular for the tumours of the oropharynx and larynx, but its efficacy for benign pathology is inconsistent. Methods: An exhaustive review of the English literature on trans-oral robotic surgery (TORS) for benign conditions was performed using PubMed electronic database. Results: The research was performed in March 2019 and yielded more than eight hundred articles, with 103 meeting the inclusion criteria and considered in the present study. Conclusions: The application of TORS for the treatment of obstructive sleep apnoea syndrome seems to be particularly well documented. Additionally, there exists a special interest in its use where high precision in limited anatomic space is required. There are still different structural and economic limitations for the application of TORS, however, the progressive technologic innovations and the increasing adoption of robotic surgery seem to encourage the uptake of this technique.

Treatment of tongue base masses in children by transoral robotic surgery

The feasibility and effectiveness of transoral robotic surgery (TORS) in children with tongue base masses (TBMs) were evaluated. Eight pediatric patients who were treated with TORS for TBMs between January 2010 and January 2016 at a tertiary hospital included in the study. All pathologies were congenital lesions: four were lingual thyroglossal ductus cysts (LTGDCs), one was a minor salivary gland tumor, one was a vallecular cyst, one was a bronchogenic cyst, and one was an ectopic thyroid tissue. TORS was performed successfully in all cases. The mean robotic set-up and exposure time was 13.0 ± 2.1 min (range 10-16 min) and the mean robotic surgery time was 8.8 ± 6.9 min (range 4-25 min). Estimated blood loss was lower than 5 ml for one patient and lower than 50 ml for another one. The remaining patients' estimated blood loss was lower than 10 ml. No patient required tracheostomy intra- or post-operatively. Only one minor complication occurred on day 10 after surgery (minor bleeding), which was resolved without intervention. No major complications or recurrence were observed. Better visualization and small, flexible arms allow surgeons to treat TBM faster and easily using TORS. This leads to decreased morbidity compared to open and transoral endoscopic/microscopic surgical methods. In the future, we believe that TORS may become the gold standard method for the treatment of pediatric TBM with continued development of robotic technology.
