A live porcine model for surgical training in tracheostomy, neck dissection, and total laryngectomy.

OBJECTIVES: Head and neck surgery is associated with a steep learning curve, creating a need for effective training methods. Live animal models can be useful in acquiring the required skills and techniques to perform tracheostomy, neck dissection, and laryngectomy. The aim of this study is to assess the feasibility and usefulness of a porcine model to teach tracheostomy, neck dissection, and laryngectomy, describing the similarities between a swine head and neck surgical model and the human cervical area. METHODS: Twelve surgical training sessions were held with the use of a live porcine model maintained under general anaesthesia; a total of 39 procedures were performed. In each session, one otolaryngology resident per year performed a procedure to acquire the targeted competencies for their respective year of training. Each procedure was time recorded and evaluated based on a modified Objective Structured Assessment of Technical Skills. Linear regression was used to analyse the data and express the results as percentages. RESULTS: Training exercises were performed in shorter times over the study period. A 9% reduction in the time spent was observed. There was a global improvement in the evaluation made by OSATS score of 6% in the first period (2018-2019) and 58% in the second period (2019-2020). CONCLUSION: The porcine model was both manageable and helpful in providing training despite slight anatomical differences between human beings and pigs. However, more studies are necessary to guarantee that the competencies acquired with this type of training are transferable to real-life interventions. LEVEL OF EVIDENCE: Level 5.

Impact of Otolaryngology theses in their authors' scientific production.

INTRODUCTION AND OBJECTIVES: The writing of a thesis has 2 main objectives: the appropriate training to be a good researcher and the publication of the first original research work. This study attempted to check this statement applied to theses in Otolaryngology by analysing the variation in the authors' publications. MATERIAL AND METHODS: We used the database TESEO to obtain the data relative to Otolaryngology theses in Spain published between 1993 and 2003. We found the publications of each author by using de programme "Publish or Perish" and we analysed the variations in their work in 3 periods (prior to, around and after thesis publication). RESULTS: The publications, the citations and the parameters analysed all increased in the second and third periods (around and after) with regard to the first period. However, there were no significant differences in some of them in the first 2 periods. CONCLUSIONS: The elaboration of a thesis in Otolaryngology increased the scientific production of its author. Almost a third of the authors did not publish any work. There was a significant increase in all the parameters studied and the bibliometric indices between the period before thesis publication and the around and after thesis periods.

[Surgical complications in salvage surgery of patients with head and neck carcinomas treated with concomitant chemoradiotherapy (CCR)]. / Complicaciones quirúrgicas en la cirugía de rescate de pacientes con carcinomas de cabeza y cuello tratados con quimioterapia y radioterapia concomitantes.

INTRODUCTION: One way of treating head and neck carcinomas is using concomitant chemoradiotherapy (CCR). In this study we will try to evaluate the incidence of complications in rescue surgery after CCR. MATERIAL AND METHOD: We have studied data from 103 patients diagnosed as having stage III or IV squamous head and neck carcinoma between 1997 and 2005. They were treated following two different CCR protocols. RESULTS: Of the 103 patients, 26 (25 %) required rescue surgery. Eight patients in this group (30.76 % of those operated on) presented complications. The average stay in our department was 52.8 days (7-197 days). CONCLUSIONS: Patients treated with CCR who have needed rescue surgery apparently have a higher rate of complications and a longer stay than those treated with surgery alone.
