Facial asymmetry is frequently detected in patients who are seeking rhinoplasty for a deviated nose, and its presence often leads to failure create straight-looking nose. To analyze the frequency characteristics of facial with nose identify representative parameters describe types severity asymmetry. Retrospective review at tertiary referral center preoperative photographs 152 underwent between January 2008 December 2012. The incidence these was compared 60 control undergoing septoplasty...
The aim of this work was to evaluate factors that influence local recurrence and survival after surgical resection sinonasal malignant melanoma, using a large population-based multicenter study in Korea.Retrospective analysis performed for 155 newly diagnosed melanoma patients gathered from 15 university hospitals throughout Korea. Demographic data, tumor characteristics, approach, adjuvant treatment, recurrence, outcomes were analyzed.Three-year 5-year overall rates 48.8% 40.1%,...
Abstract Background Distant metastases (DMs) increase in patients with recurrent head and neck squamous cell carcinoma (HNSCC). We evaluated the ability of fluorine 18‐fluorodeoxyglucose ( 18 F‐FDG) positron emission tomography/computed tomography (PET/CT) to detect DMs these patients. Method 82 consecutive histologically confirmed HNSCC. Patients previous were excluded. All received whole‐body F‐FDG PET/CT scanning for restaging HNSCC follow‐up after salvage surgery. Any suspected by...
To assess palatine tonsil size relative to degree of obesity in children with sleep-disordered breathing (SDB).Case-control study.Tertiary care rhinology clinic.We compared the subjective and objective size, including height (TH), width (TW), thickness (TT), weight (TWt), volume (TV), 26 obese age- gender-matched control SDB, 29 overweight matched controls SDB.Despite similar children, TH, TW, TT, TWt, was larger than mean TV significantly greater SDB (8.53 +/- 3.30 mL vs 6.90 2.05 mL; 95%...
Background Chronic rhinosinusitis (CRS) is a multifactorial inflammatory disease. Particularly, eosinophilic CRS often recalcitrant to treatment, so an appropriate animal model required evaluate the pathogenesis of, and develop therapies for, CRS. This study aimed improve ovalbumin (OVA)-induced mouse of eosinophilic/allergic by combining OVA with Aspergillus protease, which known trigger allergic reactions in lungs. Methods In CRS, mice were challenged intranasally protease combined OVA....
To determine whether surgery influences cardiovascular autonomic modulation in obstructive sleep apnoea syndrome (OSAS), the present study was performed to evaluate effect of upper airway (UA) on heart rate variability (HRV) using frequency domain analysis for patient groups who have had either successful or unsuccessful surgery. We compared body mass index (BMI), polysomnographic [apnoea (AI), apnoea-hypopnoea (AHI), minimum SaO(2)] and HRV [very low (VLF) power, (LF) high (HF) HF/LF ratio,...
Asian patients present with relatively poorly developed dorsal and tip height thicker skin, so augmentation rhinoplasty is the most commonly performed procedure. Tip surgery using autologous cartilage followed by an alloplastic implant material widely surgical procedure for on patients. Cartilage grafting procedures, including shield grafting, multilayer onlay modified vertical dome division, are key maneuvers building up providing better definition a tip. When performing primary cosmetic...
Conclusion: Sarcoma and lymphoma comprised 75% of 20 cases pediatric sinonasal malignancies. As regards treatment, all patients received chemotherapy 6 (30%) underwent surgery. The overall 5-year survival rate was 52%, with favorable outcome for solid tumors compared lymphoma. Objective: We aimed to investigate the clinical features treatment outcomes malignancies in patients. Methods: Clinical were evaluated staged according staging system each histologic type. Results: consisted 12 males 8...
Background Chronic rhinosinusitis (CRS) can be aggravated by viral upper respiratory infections. We aimed to investigate whether any specific human rhinovirus (HRV) serotype is more common in the mucosa of CRS patients, and find defining clinical characteristics, according various HRV serotypes. Methods A prospective case‐control study was conducted determine serotypes 111 patients 51 non‐CRS controls. No participant had a history infection over 4‐week period. Nasal lavage fluids turbinate...
This study aimed to determine frequency of external nasal deformities in patients with deviated septa and the effect endonasalseptoplasty batten grafting on appearance.The 52 who underwent a graft for correction caudal septal deviations were included study. The preoperative postoperative photographs reviewed retrospectively. Gross changes (nasal deviation, dorsal middle vault height, tip height change, nostril asymmetry) assessed. Anthropometric measurements (dorsal projection, nasolabial...
Rib cartilage is the most reliable material for structural support and dorsal augmentation in Asian rhinoplasty with its robust strength bountiful amount. Its value incomparable especially complex, cartilage-depleted revision surgery or major reconstruction. There are many articles regarding harvesting carving of rib rhinoplasty, however, only few has focused on preoperative postoperative issues. Preoperatively, evaluating availability, assessing quality quantity cartilage, choosing to...
Background and Objective To document the effect of adenotonsillectomy on prepubertal growth in children according to preoperative status follow up period. Methods The clinical records 161 with sleep breathing disorder who underwent between 1998 2007 were assessed. height, weight body mass index (BMI) was converted z-score (standard deviation scores) for their ages. Preoperative divided three groups (less than 25th percentile, 25â75th more 75th percentile). changes weight, height BMI...
The purpose of this study was to estimate the rates functional recovery facial nerve and total tumor resection in patients who undergo short anterior rerouting long removal skull base tumors.We retrospectively collected data on 37 with tumors underwent during procedure for removal. Information technique, completeness resection, changes function were obtained from medical records. Rerouting techniques classified as or rerouting.Ten 16 (62.5%) group showed postoperative palsy, all completely...

Background and ObjectivesZZFibromatosis is an uncommon soft tissue mass lesion that can occur in all anatomic sites.Fibromatoses arising the head neck region comprises of approximately 5% fibromatoses, which associated with infiltrative growth pattern thus results difficulty complete excision.The authors investigate clinical characteristics fibromatoses.Subjects MethodZZSix cases fibromatoses were analyzed from 1989 to 2011.The imaging pathologicfindings, surgical management,...
Inferior meatal antrostomy (IMA) is a widely performed surgical technique to treat postoperative maxillary mucocele.The method safe and easy perform, without major complications compared with other approaches.Facial pain after IMA rare clinical entity that can be challenging diagnose treat.The authors present an unusual case of acute facial neuralgia triggered by cold air developed IMA.The was located at the anterior-most part inferior meatus, inlet size relatively large remaining...
