[Role of carbon nanoparticles in patients with thyroid carcinoma undergoing total thyroidectomy plus bilateral central neck dissection].

Objective: To evaluate the role of carbon nanoparticles for dissecting lymph nodes and preserving parathyroid glands in patients with thyroid carcinoma undergoing total thyroidectomy plus bilateral central neck dissection.

Methods: A total of 86 patients with thyroid carcinoma undergoing primarily total thyroidectomy plus bilateral central neck dissection were randomly divided into trial and control groups. Carbon nanoparticles were injected into thyroid gland of trial group.

[The role of medical imaging plus carbon nanoparticles to manage the cervical lymph nodes in patients with thyroid carcinoma].

Objective: The purpose of this study was to discuss the role of the combination of carbon nanoparticles and medical imaging to manage the cervical lymph nodes in patients with thyroid carcinoma.

Method: Eighty one patients with thyroid carcinoma that primary treated were divided into two groups: trial group and control group. Carbon nanoparticles were injected into the thyroid gland of trial group patients.

[The combination of ultrasound and CT evaluate lymph node metastasis of thyroid papillary carcinoma in different compartments].

Objective: To evaluate the role of the combination of ultrasound and enhanced CT in analyzing lymph node metastasis in thyroid papillary carcinoma (PTC) patients by compartment.

Method: Clinical data of 115 cases (141 sides) with PTC were collected. All had undergone ultrasound in neck and enhanced CT both in neck and in mediastinum before surgery.

[Progress in the treatment for thyroid microcarcinoma].

Thyroid microcarcinoma(TMC) refers to the diameter less than 1cm in thyroid cancer. In recent years, with high frequency ultrasound and pathology diagnosis technology development and improvement, the incidence of TMC increased dramatically. However, there are a lot of controversy about its complication, treatment methods and value of treatment both in domestic and abroad.

[Diagnosis and surgical management of Hashimoto's disease coexistent with thyroid carcinoma].

Objective: To study clinical assessment and management of the Hashimoto's disease coexistent with thyroid carcinoma.

Methods: A retrospective analysis in 182 cases of Hashimoto's disease treated from 1982 to 1998 were undertaken. The preoperation assessment, surgical management and the complication after operation had been studied.

[Phonation reconstruction and function assessment after total and near-total laryngectomy].

Background & Objective: Total laryngectomy is a common surgery pattern for treating laryngeal and hypopharyngeal cancer, but patients will lost phonation function after operation. This study was to retrospectively analyze usage of modified Amatsu, and modified Pearson operation in treating laryngeal and hypopharyngeal cancers, and to analyze phonation function by subjective and objective assessment.

Methods: Clinical data of 69 patients with laryngeal or hypopharyngeal cancer treated by total or near-total laryngectomy (modified Amatsu or modified Pearson operation) in our department from 1996 to 2003 were retrospectively analyzed.

[Surgical treatment of thyroid carcinoma with the upper mediastinal invasion].

Objective: To study the surgical management of the thyroid carcinoma with the upper mediastinal invasion.

Methods: Among the 560 thyroid carcinoma cases receiving surgery from 1988 to 1999, there were 10 cases of the upper mediastinal, the 10 cases were retrospectively analyzed for their preoperative diagnosis, surgical methods and postoperative complications.

Results: The upper mediastinal invasion rate of the 560 cases was 1.

[Surgical treatment of advanced thyroid carcinoma with aero-digestive invasion].

Objective: To study the surgical management of the advanced thyroid carcinoma with aero-digestive invasion.

Methods: To analyze 18 cases of advanced thyroid carcinoma which had aerodigestive invasion retrospectively, the patients were treated from 1988 to 1998.

Results: The rate of aerodigestive invasion occur was 3.

[Combined treatment for advanced laryngeal carcinoma].

Objective: To assess the efficacy of the combined therapy for advanced laryngeal carcinoma.

Methods: 204 cases of advanced laryngeal carcinoma were treated in this department from 1984 to 1997. Patients were treated by surgery alone or combined therapy including of surgery, radiotherapy and chemotherapy.

[Application of frontal-lateral laryngectomy in laryngeal cancer treatment].

Objective: Thirty-eight patients of laryngeal cancer were treated by extended frontal-lateral laryngectomy and the results were evaluated.

Methods: Thirty-eight patients with laryngeal cancer were treated by frontal-lateral laryngectomy and the laryngeal defects were reconstructed by epiglottic flap, bi-pedicle and bi-muscle flap and epiglottic flap plus bi-pedicle and bi-muscle flap from February 1988 to February 2000. There were 29 males and 9 females, ranging in age from 32 to 72 years old.
