Background and Objectives : To determine the changes of reflux symptoms and laryngoscopic findings of patients with laryngopharyngeal reflux (LPR) on the duration of proton pump inhibitor medication. Materials and Methods : From Feb 2003 to Nov 2004, 58 patients who were diagnosed with LPR by 24-hour double-probe pH monitoring were enrolled. All patients were treated with proton pump inhibitor and followed up for 8 weeks at least. The response of symptoms and laryngoscopic findings of patients were assessed with reflux symptom index (RSI) and reflux finding score (RFS) before treatment and 2, 4, 8, 12, 16, 20 weeks after treatment. Results : The symptoms of patients with LPR were improved significantly at 2, 4, 8 weeks of treatment. The laryngoscopic findings of patients with LPR were improved significantly at 4 and 12 weeks of treatment. There was no correlation between improvement of reflux symptoms and laryngoscopic findings. Conclusions : The laryngoscopic findings of LPR patients were improved more slowly than reflux symptoms. Based on our results, anti-reflux therapy might be continued at least for 3 months until the improvement of laryngoscopic findings.

Benign symmetric lipomatosis was initially described in 1846 by Sir Benjamin Brodie. In 1888, Otto Madelung presented 33 cases of benign symmetric lipomatosis and described the classic“horse collar”cervical distribution of the lipomatous tissue. Launois and Bensaude described benign symmetric lipomatosis as a distint syndrome characterized by a diffuse, symmetric, fatty accumulation in the cervical region. This disease is rare condition affecting mostly middle aged alcoholic men and associated with many systemic diseases such as diabetes mellitus, hyperuricemia, renal tubular acidosis, liver enzyme abnormality etc. The condition does not spontaneously involute and surgical excision is the only proven method of treatment, and recurrence is frequent. We experienced six patients of benign symmetric lipomatosis who underwent surgical excision via collar incision which afford wide exposure of the entire cervical area. We report them with the review of literature.

Organ preservation surgery and minimally invasive surgery have been developed during the past 20 years with major focus on transoral laser surgery, endoscopic surgery, and robotic surgery. Two major robotic surgeries in head and neck area are transoral robotic surgery (TORS) and robotic thyroidectomy. Transoral robotic surgery is a safe and efficacious method of surgical treatment of oropharyngeal. hypopharyngeal and laryngeal neoplasm. Advantages of the technique include adequate ability to visualize and manipulate lesions with two hands. TORS can provide magnified three dimensional views and overcome the limitation resulting from the "line of sight" which hinders transoral laser procedure. The swallowing function following transoral robotic surgery show superior and patients were able to retain or rapidly regain swallowing function in the majority of cases. Recently, robotic thyroidectomy has also been developed to overcome the [imitation of endoscopic thyroidectomy. Robotic thyroidectomy by a gasless unilateral axillo-breast or axillary approach using a da Vinci S Surgical Robot is a feasible and cosmetically excellent procedure. It can be a promising alternative to endoscopic thyroidectomy or conventional open thyroidectomy.

The medical records of 87 patients with thyroid nodule treated from May 1992 to February 1996 were retrospectively reviewed to assess complication with age, sex, pathologic classification, location of lesions, and surgical procedures. The overall rate of complication were observed 10(11.5%) in thyroid surgery. The most common complication was transient hypoparathyroidism, which occurred in 6(6.9%) of 87 patients. The 2(2.3%) patients experienced Permanent hypoparathyroidism and each 1(1.1%) patient was reported in transient recurrent laryngeal nerve paralysis and hematoma.. Well-performed thyroid surgery usually produces few complications. More extensive resections, involving bilateral thyroidectomy are associated with a higher incidence of postoperative morbidity, in particular vocal cord paralysis and hypoparathyroidism, than procedures that consist essentially of unilateral thyroidectomy. Our experience suggests that the postoperative complication relates primarily to the surgical procedure. The low incidence of permanent complications in thyroid surgery suggests the feasibility of total thyroidectomy as the operation of choice when thyroid nodules were malignant and surgeons are familiar with the technique and indications.

Robotic thyroidectomy has been developed to minimize neck scarring, and several authors have described its feasibility and safety, and have reported surgical outcomes comparable with conventional open thyroidectomy. The da Vinci surgical system robot provides a three-dimensional $10-12{\times}$magnified view of the surgical area. It also provides hand-tremor filtration, fine motion scaling, and precise and multi-articulated hand-like motions. Recently, robotic technology has also been applied to lateral compartment neck dissection in thyroid cancer. We have developed a new novel selective neck dissection procedure by a gasless unilateral axillo-breast (GUAB) approach with a da Vinci Surgical System for well-differentiated thyroid carcinoma to avoid a long visible neck scar. Based on our early experience, robotic selective neck dissection by GUAB approach is a safe, feasible and cosmetically excellent procedure. It can be an alternative to conventional open surgery in the highly selected patients with well-differentiated thyroid carcinoma. The oncologic safety of robotic selective neck dissection should be verified with long-term follow-up data.

Management of laryngotracheal stenosis remains one of the most challenging problems facing the otolaryngologist. The key to success is to obtain adequate rigid circular support with normal mucosal lining. Four Patients with laryngotracheal stenosis were surgically treated in our institution in 2000. All the patients were male adults. The cause of stenosis were longterm or repeated endotracheal intubation and tracheostomy in our patients. All patients were successfully decannulated following segmental resection of the stenotic portion including the anterior arch of the cricoid cartilage and end-to-end anastomosis after suprahyoid laryngeal release. The time between treatment and decannulation was just one day in three patients. These results suggest the Possibility of early decannulation even if the cricoid cartilage was partially resected. It is better to prevent laryngotracheal stenosis rather than to treat it once it has occurred.

Liposarcoma is the second most common soft tissue sarcoma in adult. The incidence of liposarcoma in the head and neck area is very uncommon. Liposarcoma of the neck usually express non-tender palpable mass. The main treatment of cervical liposarcoma is surgical excision and adjuvant radiation therapy. Herein, we report a case of cervical liposarcoma with the review of literature.

Background and Objectives: Angiogenesis is the process of new blood vessel development from preexisting vessel. Angiogenenesis has been considered to be essential for the growth and expansion of a solid tumor. Vascular endothelial growth factor (VEGF), known as one of the most important vascular permeability factors, induces proliferation of endothelial cells, stiumulates angiogenesis, and increases vascular permeability. Several recents reports have documented that VEGF overexpression is associated with poor clinical outcomes in many maligmancies. The aims of this study were to determine whether microvessel density and VEGF expression are related to clinicopathologic factors such as age, sex, tumor size, tumor stage, and prognostic factors and to evaluate the relationship between VEGF expression and angiogenesis in benign and malignant thyroid tumors. Materials and Methods: The subjects were 65 patients (27 with papillary carcinoma, 27 with adenomatous hyperplasia, 11 with follicular adenoma) who underwent thyroidectomy from 1995 to 2001. Imuunohistochemistry was used to detect VEGF expression and microvessel density (MVD) in paraffin-embedded thryoid tumor specimens. Results: The intensity of the VEGF expression did not show stastically difference between benign and malignant thyroid tumors. There was no apparent correlation between VEGF expression and age, tumor size, T stage or scores of the AGES, AMES and MACIS systems. The neo-microvessel density was higher in the maligant tumor than the benign tumors. Also, higher neo-microvessel density was associated with metastases of the lymph nodes and scores of the AMES and AGES systems. Conclusion: Our results suggest that neo-microvessel vessel density may be a significant prognostic factor in the thyroid papillary carcinoma. But the VEGF expression does not appear to be an significant independent prognostic factor for thyroid papillary carcinoma.

Background and Objectives: Papillary thyroid microcarcinoma (PTMC) is defined as a papillary thyroid carcinoma measuring less than 10 mm along the greatest dimension. In general, prognosis of the papillary thyroid carcinoma is very favorable, but some PTMC frequently invade the surrounding soft tissue and metastasize to cervical lymph nodes. Optimal therapeutic plan was not established and the treatment strategy of the PTMC has become a subject of debate. Here, we reviewed our experiences and evaluated the characteristics of PTMC that could help in the treatment of PTMC. Materials and Methods: From January 2000 to December 2006, 354 patients who underwent surgery for papillary thyroid carcinoma were enrolled in this study. Among these patients, 142 patients with PTMC were evaluated. We subdivided the PTMC by size and compared the clinical characteristics in PTMC less than 5 mm and over than 5 mm. And we also compared the clinical characteristics of PTMC with thyroid papillary cancer over than 10 mm. Results: The mean age of patients at diagnosis was 48.3 years and the female to male ratio was 3.58. PTMC presented with signs of aggressiveness including multifocal disease (19.0%), cervical lymph node metastasis (17.4%), extrathyroid extension (20.4%) and invasion into the adjacent structure including the strap muscle, trachea and recurrent laryngeal nerve (14.0%). The PTMC, more than 5 mm in size, showed a more aggressive feature than PTMC less than 5 mm, especially in lymph node metastasis and extrathyroidal extension. Conclusion: PTMC showed the signs of aggressiveness with increasing tumor size. These findings suggest that PTMC more than 5 mm needs more extensive treatment than those less than 5 mm.
