To introduce a new injection material for vocal fold diseases, which could be readily translated to clinical practice, we investigated the effectiveness of platelet-rich plasma (PRP) on injured in terms histological recovery.Blood samples were drawn from New Zealand White rabbits and PRP was isolated through centrifugation separation samples. Using CO2 laser, made linear wound 24 sides 12 injected each with one side normal saline (NS) other. Morphologic analyses conducted at 2, 4, weeks...
This study was conducted to identify anatomical variations of the spinal accessory nerve (SAN) in upper neck, landmark anterior and inferior border level IIb, evaluate nerve's effect on number lymph nodes (LNs) IIb.Case series with planned data collection.A total 181 neck dissections (NDs) were prospectively enrolled this study. The relation between SAN adjacent structures (internal jugular vein [IJV], sternocleidomastoid muscle [SCM], cervical plexus) LNs IIb investigated.The crossed IJV...
Numerous methods have been utilized to repair nasal septal perforation with varying degrees of success; however, no consensus has reached on nasoseptal repair. Here, the authors describe a surgical method based human dermal allograft (Surederm, Hans Biomed Corp. Korea) for perforations.Eleven patients were included in this study. The causes these perforations previous surgery, trauma, foreign body (button battery), and idiopathy. There several sites perforation: 9 central area, 1...
Sudden deafness, in most cases, has no apparent cause. In some cases viral infection, vascular occlusion, or a cochlear membrane rupture may be responsible for the sudden loss of hearing. this study, we analyzed etiology, audiologic, psychiatric, and clinical aspects psychogenic deafness through retrospective chart review. Patients included were thought to have as result causes and/or stresses.We reviewed records 277 patients who had been admitted Department Otolaryngology, Kangbuk Samsung...
To evaluate the expression of cell-cycle regulators in papillary thyroid carcinoma relation to lymph node metastatic features, and determine whether immunohistochemical staining markers can predict metastasis.Cross-sectional study prior surgical specimens.Academic tertiary referral center.We reviewed clinical records patients who had undergone surgery for cancer follicular adenoma between January 2005 May 2008 at our clinic. Among these cases, 92 patients, comprising 28 with adenoma, 32...
Injection of injured rabbit vocal folds with human adipose-derived stem cells (hADSCs) led to improved wound healing and fewer signs scarring as demonstrated by a decreased collagen content in the treated compared untreated folds. hADSCs remained viable for up 12 weeks folds.The aim this study was investigate morphologic histologic properties scarred following injection hADSCs.This randomized, controlled animal study. Twenty-four from New Zealand rabbits were using CO(2) laser injected...
Objectives To investigate the relationships between lymph node metastasis (LNM) and expression of CD31, D2-40 vascular endothelial growth factors (VEGF)-A -C in patients with papillary thyroid cancer (PTC). Methods Paraffin-embedded tissues 72 were evaluated, which included 25 nodular hyperplasia (TNH), 24 PTC without LNM, 23 LNM. Three pathologists, who blinded to patient's clinical information, assessed immunohistochemical staining results. The amount was scored as high (>25% cells...
Abstract Objectives/Hypothesis Dysphonia associated with laryngeal paralysis may be identified in the short term postoperatively or develop years after successful medialization laryngoplasty. In selected cases, collagen injection permits further of one both vocal folds by small increments to improve phonation thyroplasty. The study seeks determine whether injections result measurable improvements voice quality and function when offered select patients who have received Study Design...
The impact of serum thyroid hormone levels on cancer risk is unclear. Some studies reported that elevated thyroid-stimulating (TSH) associated with higher for incidence cancer, but other no relationship. We conducted a large cohort study in 164,596 South Korean men and women who were free at baseline underwent health examination function. A parametric proportional hazard model was used to evaluate the adjusted ratio (HR) 95% CI. During 2,277,749.78 person-years follow-up, 1280 incident...
The relationship between low muscle mass (LMM) with obesity and hearing loss has been poorly studied. We aimed to investigate the association of LMM on in general population. A total 265,792 adults who underwent a test body composition analyses were included. Pre-sarcopenia was defined as having an appendicular index <5.7 kg/m2 for women <7.0 men, ≥25 kg/m2, while pre-sarcopenic co-presence obesity. Participants divided into four groups according presence pre-sarcopenia and/or prevalence...
This study aimed to assess predictors of the response varying durations proton pump inhibitor (PPI) use and lifestyle modification treatment for laryngopharyngeal reflux disease (LPRD).Between October 2014 June 2016, a prospective, multicenter, open-label, single-cohort, intention-to-treat, observational was conducted at eight referral hospitals across Republic Korea examine early late in adult patients (age ≥19 years) with LPRD. Participants underwent standard (PPI [Esomezol] modification)...
Ectopic thyroid tissue is an uncommon embryologic aberration characterized by the presence of in a site other than its usual pre-tracheal location. Single ectopic most common variant, and base tongue frequent Dual extremely rare, only eleven cases have been reported English literature. Furthermore, adenomatous hyperplasia has never to arise from dual thyroid. There one case arising single intratracheal We report that presented as sublingual mass 37-yr-old woman. The diagnosis was made...

Currently, a variety of materials are available for the treatment glottal insufficiency. Ideal injection should be inexpensive, easily obtainable, nontoxic, and biocompatible. Plasma gel has recently been developed as an injectable, autologous material used in plastic surgery. The aim this study was to evaluate histological changes rabbit vocal folds (VFs) after plasma gel, compared with collagen (Artecoll) or hyaluronic acid (Reviderm Intra).Experimental prospective animal study.Animal...
Recently, automation in clinical test is raised as a fusion of bio and robotic technology. Particularly, becomes new application area the In this paper, we present robot platform for suitable small or medium size hospitals. The designed to minimize consumption reagents, easily integrate various testing equipments since it functionally modularized. aimed accommodating almost 70 kinds tests, which are most frequently conducted consists several major function blocks such manipulation,...
The purpose of this study was to analyze the psychological characteristics patients with vocal nodules and establish relationship between these development nodules.A tertiary medical centre.The patient group consisted 41 housewives nodules, control 35 who did not have any pathology. subjects completed questionnaires related voice disorder Symptom Checklist-90-Revision.The scores less than 1 year symptom duration (acute) more (chronic) were also compared those controls.The total differed...
Background Cepstral analysis which is obtained from Fourier transformation of spectrum has been known to be effective indicator analyze the voice disorder. To evaluate disorder, phonation sustained vowel /a/ sound or continuous speech have used but former was limited capture hoarseness properly. This study aimed compare effectiveness in cepstrum between and speech. Methods From March 2012 December 2014, total 72 patients enrolled this study, including 24 unilateral vocal cord palsy, nodule...
