What´s new in PubMed this week


Zhao Z, Zhang Y, Lin L, Huang W, Xiao C, Liu J, Chai G. Intelligent electromagnetic navigation system for robot-assisted intraoral osteotomy in mandibular tumor resection: a model experiment. Front Immunol. 2024 Jul 25;15:1436276. doi: 10.3389/fimmu.2024.1436276. PMID: 39119338; PMCID: PMC11306084.

Free in PubMed Central. A preclinical study on a robotic arm prototype built for navigation guided osteotomy. The study was performed on printed 3D models simulating a transoral resection. It is feasible. Authors postulate that it may enhance the precision of clinical surgery.

Chinese again.


Wang L, Zhong Q, Yang F, Hou L, Ma H, Feng L, He S, Yang Y, Fang J, Wang R. Evaluation of different methods of transoral minimally invasive surgery for supraglottic laryngeal carcinoma. Cancer Rep (Hoboken). 2024 Aug;7(8):e2077. doi: 10.1002/cnr2.2077. PMID: 39118227.

I cannot find the contributions of this study.


Akbar MD, Taufique AK, Kamran DA, Harris AR, Lyons J. Assessment of Transoral Robotic Surgery (TORS) Content on YouTube. Cureus. 2024 Jul 4;16(7):e63857. doi: 10.7759/cureus.63857. PMID: 39099932; PMCID: PMC11297799.

According to the present study, there is a quantifiable lack of material regarding patient experience with TORS on YouTube”.


Troise S, Arena A, Barone S, Raccampo L, Salzano G, Abbate V, Bonavolontà P, Romano A, Sembronio S, Robiony M, Califano L, Dell’Aversana Orabona G. Transoral robotic surgery in maxillofacial surgery: Systematic review of literature on current situation and future perspectives. Curr Probl Surg. 2024 Aug;61(8):101504. doi: 10.1016/j.cpsurg.2024.101504. Epub 2024 May 18. PMID: 39098337.

This is a free article.

This an absurd point of view. Is does not exist such a thing as “transoral robotic surgery in maxilofacial sugery”. Just look a the search strategy: “transoral robotic surgery” OR “TORS” AND “maxillofacial surgery” OR “face” OR “orofacial”. And look at the results: “Given the small number of articles, derived using these keywords, also a search using the mesh terms “transoral robotic surgery” AND “Head and Neck” was performed”.

Absurd point of view, absurd results. The paper is discussing TORS. That it, is discussing a part of the application of robotic surgery in Head&Neck Surgery, which is the transoral approach. Therefore excluding remote access techniques, but also the transoral/transvestibular approach

TransOral Robotic Surgery (TORS) is a set of surgical techniques designed introducing “at least three” robotic telemanipulated arms through the mouth. Weinstein and O´Malley set the technique, named it, made the preclinical investigations and led the first clinical trial. From year 2004 to 2007 they described the basic techniques on the oropharynx (radical tonsillectomy and base of the tongue resection) and the larynx (supraglottic laryngectomy), and also introduced the transoral approach to the anterior cranial base. TORS was next used for oral disesases (including transoral approach to the submandibular gland), and of course to access the parapharyngeal space (including Eagle´s syndrome) and retropharyngeal space (see bellow) . Also the transoral approach to the thyroid gland was converted into transoral / transvestibular. and popularized.

TORS for Eagle´s syndrome

So, what is the paper about?

Again, a misunderstanding. Check this letter co-written with Greg Weinstein: Adjusting the focus of transoral robotic surgery. This was 2015, almost ten years ago.

Another way to underline the absurdity. Take the next meeting of the APTS. Do you imagine we were talking about “General Surgery Robotic Thyroidectomy” and “Otolaryngology-Head&Neck Surgery Robotic Thyroidectomy” to name the same thing? We are surgeons pushing forward together, learning from each other.

“The transcervical approach was the most utilized to resect the tumors, although in recent years trans-oral robotic surgery (TORS) has also been used”
