The role of MMP-2, MMP-9, and TIMP-1 in the pathogenesis of nasal polyps: Immunohistochemical assessment at eight different levels in the epithelial, subepithelial, and deep layers of the mucosa

April 28, 2015  |  Nuray Bayar Muluk, MD; Osman Kürşat Arikan, MD; Pınar Atasoy, MD; Rahmi Kiliç, MD; Eda Tuna Yalçinozan, MD

Abstract

We conducted a prospective study to investigate the role of matrix metalloproteinase-2 (MMP-2), matrix metalloproteinase-9 (MMP-9), and tissue inhibitor of metalloproteinase-1 (TIMP-1) in the pathogenesis of nasal polyps. Our study group consisted of 24 patients-21 men and 3...

Unusual presentations of choanal polyps: Report of 3 cases

February 12, 2014  |  Ali Ozdek, MD; Halil Erdem Ozel, MD

Abstract

Most choanal polyps arise from the maxillary sinus, and they are called antrochoanal polyps. Their typical endoscopic and radiologic appearance makes them easy to diagnose. However, some choanal polyps originate in unusual sites in the paranasal sinuses and nose, such as...

Laryngeal tuberculosis: Use of videostroboscopy in diagnosis

February 12, 2014  |  Michelle Levian, DO; Amy Chapman, MA-SLP; and Reena Gupta, MD

The diagnosis of laryngeal tuberculosis is often suspected clinically, but in patients with less specific symptoms, flexible laryngoscopy may reveal only an inflammatory picture.

Abstract

Nasal polyps were once believed to originate in sinus cavities, and from there to pass through ostia and into the nasal cavity. However, data gained from subsequent anatomic studies revealed that they can actually originate in numerous locations in the sinonasal area. We report...
