OBJECTIVES To determine the biomechanical characteristics of septal cartilage (SC) and costal cartilage (CC) taken from fresh cadavers using tensile testing and to establish CC graft material of a suitable thickness (ie, with tensile characteristics closest to those of SC). METHODS Grafts of varying thickness were harvested from the central part of the(More)
OBJECTIVES The aim of this study was to investigate the effect of corticosteroid treatment on topical and systemic metalloproteinase levels of patients with nasal polyposis (NP). STUDY DESIGN Prospective clinical trial. METHODS The study included patients undergoing a paranasal sinus operation due to NP. Oral corticosteroid therapy was performed on all(More)
Adenoid cystic carcinoma is a malignant epithelial tumor of the salivary glands. It accounts for less than 1% of all head and neck cancers and less than 10% of all salivary gland neoplasms. It shows slow and indolent growth rate, low probability of regional nodal metastases, high propensity for perineural invasion, multiple and/or delayed recurrences and(More)
OBJECTIVE The aim of this study was to compare the biomechanical properties of septal cartilage (SC) and costal cartilage (CC) grafts harvested from different ribs and to find at which level CC has characteristics closest to SC. STUDY DESIGN Experimental cadaver study. SETTING Istanbul Training and Research Hospital. MATERIAL AND METHOD Cartilage(More)
Electroneurography (ENoG) is one of the most objective tests in grading the damage and prediction of prognosis in peripheral facial palsy (PFP). We aimed to determine temporal changes of ENoG recorded over occipitalis muscle in acute idiopathic PFP. Consecutive 21 patients with unilateral acute idiopathic PFP and age- and sex-matched 15 healthy volunteers(More)
BACKGROUND Although, lactoferrin (LF) is the second most important antimicrobial and anti-inflammatory peptide after lysozyme in upper respiratory tract, little is known about its role in chronic rhinosinusitis (CRS). Recent studies pronounced that LF levels were significantly reduced in CRS with nasal polyposis (NP) compared with other subgroups. However,(More)
The lateral crus plays a significant role in the aesthetic appearance of the nose. Excessive concavities of the lower lateral crura can lead to heavy aesthetic disfigurement of the nasal tip and to insufficiencies of the external nasal valve. The lateral crus of the alar cartilage may also cause a concavity of the alar rim and even collapse of the alar rim(More)
BACKGROUND Carcinoma of the thyroid gland is one of the most commonly encountered endocrine malignancies. Papillary carcinoma is the most common histological type, and its spread is usually lymphatic. About 30-80% patients with papillary carcinoma develop lymphatic metastases. CASE REPORT We present here the case of a 70-year-old female patient who had(More)
OBJECTIVES/HYPOTHESIS To investigate the histologic consequences of simultaneous nasal glucocorticosteroid and xylometazoline HCl administration in the rabbit nasal mucosa. STUDY DESIGN Prospective randomized study. METHODS Twenty New Zealand male rabbits were randomly placed into three groups: group I, control (n = 6); group II, xylometazoline HCl (n =(More)
We conducted a prospective study to evaluate the vertebrobasilar system in adults with and without obstructive sleep apnea (OSA). Our study population was made up of 48 patients with OSA and 21 healthy volunteers who served as controls; the OSA patients were subdivided into one group with mild or moderate OSA (n = 22) and another with severe OSA (n = 26).(More)
