Abstract Objectives: It is well established that tonsillar squamous cell carcinomas have a high probability of disseminating to the neck. An ipsilateral neck treatment mandatory during initial stages II IV carcinomas. However, as yet, no consensus exists whether perform elective contralateral management. Materials and Methods: A retrospective analysis 43 N0‐3 cancer patients with clinically negative necks from 1992 2002 was performed. All had dissection. Surgical followed by postoperative...
Abstract Objectives/Hypothesis: Treatment and management of tracheal defects remain challenging in head neck surgery. Various reconstruction techniques have been used, with no consensus on the best approach. The purpose this study was to explore a novel strategy fabricate tissue‐engineered trachea by using fibrin/hyaluronic acid (HA) composite gel evaluate feasibility creating cartilage. Study Design: A preliminary animal experiment. Methods: Chondrocytes from rabbit cartilage were expanded...
Purpose Radiation-induced oral mucositis limits the delivery of high-dose radiation to head and neck cancer. This study investigated effectiveness epicatechin (EC), a component green tea extracts, on radiation-induced in vitro vivo. Experimental Design The effect EC cytotoxicity was analyzed human keratinocyte line HaCaT. apoptosis, change mitochondrial membrane potential (MMP), reactive oxygen species (ROS) generation changes signaling pathway were investigated. In vivo therapeutic effects...
Particle image velocimetry (PIV) permits investigation of the distribution and velocity airflow in nasal cavity. During breathing, main laminar flow stream passes through middle meatus turbulent can be detected under physiologic conditions.Physical models or casts cavity have been utilized several studies an effort to understand its aerodynamics. PIV is a new technique for measuring aerodynamic properties tubular structures. In this article we evaluate characteristics during breathing normal...
Abstract Background The gene encoding fibroblast growth factor receptor 1 ( FGFR1 ) is emerging as a therapeutic and prognostic biomarker in various cancer types, including head neck squamous cell carcinoma (SCC). Here, we investigated the clinicopathologic implication of amplification protein overexpression hypopharyngeal laryngeal SCC. Methods Fluorescence situ hybridization immunohistochemistry were performed to determine 209 surgically resected cases. Results observed 8 (8/66, 12.1%; 6...
Benign neck masses are usually found in younger patients, who more likely to be concerned about postoperative scars. Until recently, a direct approach through transcervical incision along the mass has been accepted as standard surgical procedure for benign mass. However, this conventional leaves visible scar on neck, regardless of size incision. We assumed that an endoscopic gasless axillo-breast (A-B) might good alternative method excision masses. The aim study was determine safety and...
To evaluate the oncologic and functional results of larynx-preserving partial pharyngectomy (LPP) via lateral pharyngotomy approach as a primary treatment for small (T1 or T2) hypopharyngeal squamous cell carcinoma (HPSCC).We performed retrospective review 23 patients who underwent LPP through HPSCC at our department between January 1991 June 2007. Fourteen (61%) had adjuvant postoperative radiotherapy.The 2-years 5-years disease specific survival rate was 77% 61%, respectively. Nine (39%)...
Conclusion. The overall duration and reciprocity of the nasal cycle were not changed after allergen provocation. immediate response was 38 min, but amplitude increased significantly provocation.Objective. Nasal airflow is asymmetrical subjected to spontaneous reciprocal changes which are referred as cycle. Limited information available on how this affected by allergens. purpose study evaluate effects provocation cycle.Materials methods. This performed 25 patients with allergic rhinitis...
BACKGROUND: Several studies on seasonal variation in benign paroxysmal positional vertigo (BPPV) have been reported. However, the association between season and BPPV remains controversial; thus, further study is required. OBJECTIVE: We analyzed patients with to evaluate monthly variations. METHODS: Patients seen 2013 2017 were retrospectively enrolled this study. Differences among months seasons of visits analyzed. divided into two groups according age (65 years or older younger than 65...

Olfactory dysfunction, a reduced or complete loss of the ability to smell, is gaining attention because its substantial impact on an individual's quality life and possibility that it important sign underlying disease. However, olfactory dysfunction underdiagnosed in general population due diagnostic difficulty unpredictable prognosis. This study aimed evaluate prevalence clinically diagnosed South Korea by using well-organized, nationwide, population-based cohort data, associations between...
Hereditary angioneurotic edema (HAE) is an autosomal dominant disease resulting from a deficiency of functional C1-esterase inhibitor. If not recognized promptly and treated properly the can result in fatal outcome as it causes laryngeal edema, which lead to life-threatening acute upper airway obstruction. We present case 37-year-old female with HAE larynx, who was diagnosed early properly, together review literature.

Schwannoma, also known as a neurilemmomas or neurinomas, is benign peripheral nerve sheath tumors arising from the Schwann cells. About 25~45 % of all schwannomas are found in head and neck region, majority parapharyngeal space. Schwannoma larynx very rare with an incidence 0.1~1.5% laryngeal tumors. Recently, we experienced case pedunculated schwannoma left aryepiglottic fold 80-year-old patient. The tumor was completely excised under direct laryngoscopy use CO2 laser subsequently confirmed...
