The Use of Tactile Sensors in Oral and Maxillofacial Surgery: An Overview

Abstract

Background: This overview aimed to characterize the type, development, and use of haptic technologies for maxillofacial surgical purposes. The work aim is to summarize and evaluate current advantages, drawbacks, and design choices of presented technologies for each field of application in order to address and promote future research as well as to provide a global view of the issue. Methods: Relevant manuscripts were searched electronically through Scopus, MEDLINE/PubMed, and Cochrane Library databases until 1 November 2022. Results: After analyzing the available literature, 31 articles regarding tactile sensors and interfaces, sensorized tools, haptic technologies, and integrated platforms in oral and maxillofacial surgery have been included. Moreover, a quality rating is provided for each article following appropriate evaluation metrics. Discussion: Many efforts have been made to overcome the technological limits of computed assistant diagnosis, surgery, and teaching. Nonetheless, a research gap is evident between dental/maxillofacial surgery and other specialties such as endovascular, laparoscopic, and microsurgery; especially for what concerns electrical and optical-based sensors for instrumented tools and sensorized tools for contact forces detection. The application of existing technologies is mainly focused on digital simulation purposes, and the integration into Computer Assisted Surgery (CAS) is far from being widely actuated. Virtual reality, increasingly adopted in various fields of surgery (e.g., sino-nasal, traumatology, implantology) showed interesting results and has the potential to revolutionize teaching and learning. A major concern regarding the actual state of the art is the absence of randomized control trials and the prevalence of case reports, retrospective cohorts, and experimental studies. Nonetheless, as the research is fast growing, we can expect to see many developments be incorporated into maxillofacial surgery practice, after adequate evaluation by the scientific community.

Impact of the COVID-19 Pandemic on the Diagnosis and Management of Non-Melanoma Skin Cancer in the Head and Neck Region: A Retrospective Cohort Study

“…The COVID-19 has underscored the critical need for resilient healthcare strategies, highlighting the necessity for flexible, robust approaches in oncological surgery to ensure sustained high-quality care amidst future healthcare challenges [38]. Our results will inform strategies to maintain the level of care in the face of potential future healthcare disruptions [39].…”

Intelligent Healthcare Platform for Diagnosis of Scalp and Hair Disorders

“…AI technologies have been extensively applied in medical fields including diagnosis, treatment, surgery, screening, and epidemiology analysis due to their effectiveness and usefulness [14,[30][31][32][33][34][35][36][37]. However, they have some potential concerns in clinical practice.…”

The Role of Large Language Models (LLMs) in Providing Triage for Maxillofacial Trauma Cases: A Preliminary Study

“…The deployment of these models raises some concerns regarding potential biases in algorithmic decision making, adherence to medical regulatory frameworks, risk of hallucination, and privacy issues [23][24][25][26]. As a result, an empirical validation of their outputs still remains mandatory at this time [27]. The integration of LLMs into established healthcare infrastructures and their reliance on comprehensive high-quality datasets are non-trivial challenges that necessitate prompt and careful consideration [2].…”
