OBJECT The purpose of this study was to analyze preoperative predictors of endocrinological remission following endonasal endoscopic resection of therapy-resistant prolactin-, growth hormone (GH)-, and adrenocorticotropic hormone (ACTH)-secreting pituitary adenomas and to establish benchmarks for cure by using the most recent consensus criteria.

BACKGROUND Synechia and stenosis formation after endoscopic sinus surgery (ESS) represents a potential source of surgical failure. Mitomycin C (MMC) has been used successfully in other fields to decrease postoperative scar formation. We hypothesize that the topical application of MMC reduces the incidence of stenosis and synechia formation after ESS. (More)
The authors describe a prospective pilot study designed to investigate the use of topical nasal antifungal spray in addition to systemic steroids and itraconazole in the treatment of allergic fungal sinusitis. Sixteen patients with a history of allergic fungal sinusitis were given fluconazole nasal spray and followed for 3 months. Stabilization or(More)
Endoscopic endonasal transsphenoidal surgery (ETSS) is an effective, minimally invasive approach for the resection of anterior skull base tumors. Cerebrospinal leakage is a common complication, and repair of the anterior skull base defect with alloplastic materials has been used to minimize the risk of postoperative CSF rhinorrhea and meningitis. Injectable(More)
BACKGROUND The purpose of this study was to investigate the impact of serum eosinophilia in the prognosis of chronic rhinosinusitis (CRS). Eosinophils are now considered to play a major role in the pathogenesis of CRS. To date, no study has evaluated the clinical course of patients with CRS and serum eosinophilia. METHODS A retrospective chart review of(More)
OBJECTIVE/HYPOTHESIS To identify the incidence of methicillin-resistant Staphylococcus aureus (MRSA) causing chronic rhinosinusitis (CRS) and identify whether antibiotic use and previous endoscopic sinus surgeries (ESS) contribute to its development. STUDY DESIGN A retrospective case control analysis, with the control group randomly selected and matched(More)
BACKGROUND The main objective in this preliminary experiment was to compare gene expression in the sinus mucosa of patients with chronic hyperplastic rhinosinusitis (CRS) against normal subjects, using gene microarray technology. The specific aim was to examine alterations in inflammatory mediator expression in patients with CRS. We performed a prospective(More)
HYPOTHESIS The incidence of chronic hyperostotic rhinosinusitis has been underreported due to poor recognition of the disease process. The surgical management of chronic hyperostotic rhinosinusitis with prolonged pre and post-operative antibiotic therapy can alter clinical course of the disease process. STUDY DESIGN A prospective study of 40 patients(More)
OBJECTIVE Surgery to the internal nasal valve is presently approached either externally via an open rhinoplasty incision or transnasally. The endoscopic approach has become the preferred method of access to various other sinonasal conditions. The goal of this study was to evaluate 1) whether the internal nasal valve could be accessed and evaluated(More)
