  • Ultrasound measurement of anterior neck soft tissue thickness and its correlation with obstructive sleep apnea
    European Respiratory Journal, 2014
    Co-Authors: Rene Franco-elizondo, Shweta Gupta, Jorge Mora, Ganesan Murali, Arshad A. Wani
    Abstract:

    Background : Excessive fat tissue deposition anterolaterally to the upper airway has been identified as a contributing factor to the development of OSA. 1 Objective : To explore the relationship of soft tissue thickness of the anterior neck, measured by ultrasonound, with the presence and severity of OSA. Study and Methods : Cross-Sectional Study. Ultrasound measurements of anterior neck thickness at the vocal cords(VC), Thyroid Isthmus(TI) and suprasternal notch(SN) were assessed in 106 patients in both supine and sitting positions. BMI, Neck circumference (NC) and Modified Mallampati score (MM) were obtained. All patients underwent a one-night polysomnogram where presence and severity of OSA were determined. Results : Ultrasound measurements of the anterior neck thickness at all levels were found to be positively correlated with AHI both in supine and sitting positions(table 1). In a multivariate linear regression analysis, anterior neck thickness at the level of the TI measured during supine(22.85 +/-9.41, 95% CI 4.18-41.51; p=0.017) and sitting (18.81 +/-8.29, 95% CI 2.36-35.26; p=0.025) positions remained positively and significantly correlated with AHI after correcting for age, BMI, NC, MM and gender. Conclusions : In our study group, ultrasound measurement of anterior soft tissue thickness at the level of the Thyroid Isthmus appears to be positively correlated with AHI. References : 1.

  • ultrasound findings of papillary Thyroid carcinoma originating in the Isthmus comparison with lobe originating papillary Thyroid carcinoma
    American Journal of Roentgenology, 2014
    Co-Authors: Soo Yeon Hahn, Bookyung Han, Jung Hee Shin
    Abstract:

    OBJECTIVE. The goal of this study was to analyze the differences in ultrasound characteristics of papillary Thyroid carcinoma (PTC) originating in the Thyroid Isthmus versus that originating from the lobes. MATERIALS AND METHODS. From a retrospective review of our institution's database of records dated between January 2007 and December 2008, we identified 48 patients with classic PTCs located in the Isthmus. All the patients had undergone preoperative ultrasound imaging, total Thyroidectomy with bilateral central lymph node dissection, and postoperative follow-up for at least 2 years. As a control group, 96 patients with classic PTCs located in the lobe who had undergone total Thyroidectomy with bilateral central lymph node dissection during the same period were randomly matched to the study patients for age, sex, and tumor size. RESULTS. According to the clinicopathologic analyses, the incidence of extraThyroidal extension was higher in the patients with a tumor originating in the Isthmus than in the co...

  • Papillary Thyroid carcinoma of the Isthmus: Total Thyroidectomy or Isthmusectomy?
    American journal of surgery, 2017
    Co-Authors: Ioannis Vasileiadis, Georgios Boutzios, Maria Karalaki, Evangelos P. Misiakos, Theodore Karatzas
    Abstract:

    Abstract Background Papillary Thyroid carcinoma (PTC) is the most common histological type of differentiated Thyroid malignancy. Although the majority of PTC is located in the Thyroid lobes, a small minority arise from the Thyroid Isthmus. The reported incidence of PTC arising in the Thyroid Isthmus ranges from 1% to 9.2%, probably reflecting variation in the study populations. Purpose This review aimed to analyze the data about the optimal management of PTC arising in the Isthmus. Data sources We performed a systematic review of PubMed, MEDLINE, EMBASE, Scopus, and Cochrane Central Register of Controlled Trials to identify eligible studies analyzing surgical management strategies and published outcomes of isthmic PTC. Results Most reports support that papillary Thyroid carcinomas originating in the Isthmus are more likely to have multiple foci, invasion of Thyroid capsule and adjacent tissues with increased rate of central node involvement, compared to carcinomas located in other parts of the Thyroid. Conclusions The extent of the surgical resection, the role of prophylactic central neck dissection and the extent of central neck dissection in surgery for isthmic PTC remain highly controversial. However, total Thyroidectomy and central node dissection may be an appropriate treatment for these patients.

  • Papillary Carcinoma Located in the Thyroid Isthmus
    World Journal of Surgery, 2009
    Co-Authors: Yong Sang Lee, Jong Ju Jeong, Kee-hyun Nam, Woong Youn Chung, Hang-seok Chang, Cheong Soo Park
    Abstract:

    Background The purpose of the present study was to evaluate the clinicopathologic characteristics and short-term outcomes of papillary Thyroid carcinomas (PTC) located in the Isthmus compared to tumors located in other Thyroid regions, and to use those findings to establish a surgical strategy for treating these tumors. Patients and methods Thyroidectomy was performed in 1,973 Thyroid cancer patients in our hospital between January 2006 and December 2007. The patients were analyzed in two groups; group I, patients with tumors located in the Isthmus ( n = 181) and group II, patients with tumors located in other Thyroid regions ( n = 1,792). The clinicopathologic characteristics and short-term outcomes were compared between the two groups. Results The study groups were similar in terms of age and gender ratio. For groups I and II, respectively, the mean primary tumor size was 1.02 cm and 1.13 cm ( p = 0.017), capsular invasion frequency was 70.2 and 60.8% ( p = 0.008), and multifocality frequency was 48.6 and 39.8% ( p = 0.006). In addition, central node involvement was 40.3 and 42.1% ( p = 0.350), and lateral node involvement was 9.4 and 18.2% ( p = 0.001). At the time of postoperative iodine-131 remnant ablation, 34.3% of group I patients and 38.0% of group II patients showed undetectable serum thyroglobulin concentrations. There were no significant differences in surgical complications between the two groups. Conclusions Papillary Thyroid carcinomas located in the Isthmus was more likely to be associated with multiple foci in bilateral lobes and higher rates of capsular invasions than tumors in other Thyroid regions. These findings indicate that total Thyroidectomy is an appropriate initial surgical procedure for the isthmic PTC.
