Current therapeutic options for low-risk papillary thyroid carcinoma: Scoping evidence review.

Most cases of thyroid carcinoma are classified as low risk. These lesions have been treated with open surgery, remote access thyroidectomy, active surveillance, and percutaneous ablation. However, there is lack of consensus and clear indications for a specific treatment selection. The objective of this study is to review the literature regarding the indications for management selection for low-risk carcinomas. Systematic review exploring inclusion and exclusion criteria used to select patients with low-risk carcinomas for treatment approaches. The search found 69 studies. The inclusion criteria most reported were nodule diameter and histopathological confirmation of the tumor type. The most common exclusions were lymph node metastasis and extra-thyroidal extension. There was significant heterogeneity among inclusion and exclusion criteria according to the analyzed therapeutic approach. Alternative therapeutic approaches in low-risk carcinomas can be cautiously considered. Open thyroidectomy remains the standard treatment against which all other approaches must be compared.

Preoperative predictors of difficult oropharyngeal exposure for transoral robotic surgery: The Pharyngoscore.

BACKGROUND: Insufficient exposure may require termination of procedure in transoral robotic surgery (TORS). The aim of study was to develop a "Pharyngoscore" to quantify the risk of difficult oropharyngeal exposure (DOE) before TORS. METHODS: Three-hundred six patients undergoing any surgical procedure at one Academic Hospital were prospectively enrolled. Oropharynx was exposed with Feyh-Kastenbauer retractor. Exposure was evaluated by direct and endoscopic visualization of the four oropharyngeal subsites. Preoperative clinical/anthropometric parameters were studied in good oropharyngeal exposure and DOE groups. Logistic regression was performed to explore association between clinical/anthropometric parameters and DOE. Statistically significant parameters at multivariate analysis were incorporated into a nomogram. RESULTS: Sixty-five (21.2%) subjects were characterized by DOE. Variables associated with DOE at univariate analysis were male (p = 0.031), modified Mallampati Class (MMC) ≥ III (p < 0.001), smaller interincisor gap (p < 0.001), and larger neck circumference (p = 0.006). MMC, interincisor gap, and neck circumference were significant at multivariate analysis and were presented with a nomogram for creating the Pharyngoscore. CONCLUSIONS: The Pharyngoscore is a promising tool for calculating DOE probability before TORS.

Anatomy, technique, and results of robotic retroauricular approach to neck dissection.

In the attempt to improve the cosmetic and functional outcomes in head and neck surgeries, robotic or video-assisted neck dissection using remote access has gained ground in recent years. Retroauricular approach emerged as the most versatile option, allowing proper dissection at all neck levels. In this technique, after retroauricular incision, a skin flap is elevated and a self-retaining retractor is placed, creating working space for the robotic, or endoscopic neck dissection. Numerous published series have shown the safety and favorable outcomes of retroauricular robotic neck dissections, without any major complications or surgery-related deaths. The only consistently reported disadvantage is a longer operative time. Our group has an experience of 190 retroauricular neck dissections performed over the last 5 years, without any major setbacks. The oncologic and safety outcomes have been comparable to the conventional technique, with clearly superior aesthetic results. In the process of expansion of Robotic Surgery in Brazil, our center is currently providing training and proctoring to capacitate other head and neck surgeons, and enable other centers to offer this surgical modality.
