Background and Objective : Laryngeal microscopic surgery (LMS) is popular method to treat for vocal polyp. There is not always the improvement of the voice after operation. Many methods have been developed for better outcome of the surgery. The purpose of this study is to investigate the effect of the triamcinolone injection at vocal cord during LMS. Materials and Methods : The medical records of 28 patients, received LMS under diagnosis of vocal polyp, were retrospectively reviewed. The patients were divided into two groups depending on whether triamcinolone injected or not (case group : Triamcinolone-injected group, control group : Triamcinolone-not injected group). The quality of voice was evaluated by GRBAS scale, fundamental frequency (Fo), jitter, shimmer and NHR (Noise to harmonic ratio) at previous operation, 4 weeks after operation, 8 weeks after operation. Each voice analysis factor was compared between case group and control group by Independent t-test. Results : The mean differences of each voice analysis factor. The mean difference of Jitter, Shimmer, NHR in case group were lower than in control group, and mean difference of GRBAS scale in case group were higher than in control group. These differences were not significant (p>0.05). Conclusion : Though there was a tendency of better voice outcome in patients of triamcinolone-injection, it may not be concluded that the triamcinolone injection is helpful for better voice outcome in surgery of vocal polyp due to statistical insignificance.

Patients with tracheoesophageal fistula show signs of aspiration, possibly leading to pneumonia, which could be fatal to bed-ridden patients. Tracheoesophageal fistula occurs as a complication of intubation, tracheostomy tube insertion and nasogastric tube insertion. Possible etiology is pressure and ischemic necrosis given by tracheostomy tube and nasogastric tube to trachea and esophagus; or in some cases, larynx and hypopharynx. Meanwhile, for repair of tracheoesophageal fistula, transcervical approach can be considered but takes relatively long operation time and is not appropriate for patients with underlying diseases. We report a case of tracheoesophageal fistula complicated several years after tracheostomy tube and nasogastric tube insertion who came to medical attention with signs of aspiration. Authors successfully performed repair of the fistula under laryngeal microsurgery approach without skin incision and dissection, and thereby report the experience with review of literature.

Background and Objectives : Vocal polyps are caused by inflammation induced by stress or irritation. Many patients with vocal polyps complain voice discomfort. For vocal polyps, surgery such as laryngeal microsurgery has been the mainstay of management. We analyzed the clinical features of vocal polyps, and how the size and location of vocal polyps affect the outcomes of surgery. Methods : We retrospectively reviewed 42 patients from March 2014 to December 2015, who were diagnosed as unilateral single vocal polyp. When we operated on a vocal polyp with laryngeal microscopy, we measured their size and location. The quality of voice was evaluated by GRABS scale, jitter, shimmer, NHR (noise to harmonic ratio), MPT (maximum phonation time), and VHI (voice handicap index) before operation and 4 weeks after operation. Results : When we divided the patients into large-sized vocal polyp group (the longest length >3 mm) and small-sized vocal polyp group (the longest length ${\leq}3mm$), all parameter differences tend to be greater at large sized vocal polyp. However, these differences were not statistically significant (p>0.05). When we divided into two groups depending on the volume of vocal polyp, no distinct tendency was found. When we compared the location (anterior, mid and posterior) of vocal polyp with the improvement of voice quality, more change was found at mid portion vocal polyp, except the difference of VHI. However, these differences were also not statistically significant (p>0.05). Conclusion : All parameter differences tend to be greater at large vocal polyp and polyp of the mid location.

Foregut cystic developmental malformations are rare developmental anomalies. It is important to diagnose the diseases and manage them properly because these cysts may generate feeding or respiratory difficulties depending on the size and location of the lesions. A newborn was referred for a congenital cervical swelling to our clinic on the second day of his life. Neck SONO and MRI showed an about 6cm sized cystic mass at left submandibular area. Aspirations and sclerotherapies were done repeatedly due to recurred cystic mass. Under the suspicious of cystic hygroma, the mass and submandibular gland were excised. Histologically, it was a benign cyst including gastrointestinal and bronchogenic mucosa and pancreatic tissue. Foregut cyst was suggested for the final diagnosis and the patient was discharged at 9 days after the operation without a complication. He has visited our out-patient department. Although several image studies have been introduced to find out foregut cyst, it is difficult to go through differential diagnosis because of similarity of other benign tumor. Further studies for early diagnosis of cervical foregut cyst are needed for preventing possible related problems.

Malignant lesion of the trachea predominantly results from direct spread of adjacent tumors, whereas primary tracheal malignancies are rarely observed. Tracheal tumors are usually diagnosed late on account of delayed specific symptoms: dyspnea, stridor, coughing and hemoptysis. Primary tracheal tumors, although very rare, may extend into the thyroid gland and present as a thyroid mass. Surgery, followed by adjuvant radiotherapy, is the treatment of choice. A case of primary tracheal cancer with thyroid invasion is reported, and a review of the literature is presented.

Solitary fibrous tumor (SFT) is an uncommon spindle cell neoplasm that is usually presented as a pleural origin localized tumor. There are few cases, found in thyroid. Twenty six cases found in thyroid have been reported since 1993, and two of these were malignant. We report another malignant case in this study; a 55 years old man visited out-patient clinic due to palpable mass of anterior neck, and pathologically diagnosed as malignant SFT of thyroid after surgical resection. In this study, we focus on the clinical features of this uncommon disease along with other literature reviews.
