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

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 women, aged 23 to 70 years (mean: 45.97 ± 11.60)-with nasal polyposis who underwent functional endoscopic sinus surgery. For comparison purposes, we assembled a control group of 11 patients-6 men and 5 women, aged 18 to 56 years (mean: 29.90 ± 14.22)-without nasal polyps who underwent septoplasty and/or rhinoplasty. We analyzed 36 polyp specimens obtained from the study group (10 from the nasal cavity, 10 from the maxillary sinus, and 16 from the ethmoid sinus) and 11 tissue specimens from the control group (each control provided 1 specimen from the inferior turbinate). We then calculated the mean number of these cells in the epithelium, subepithelial layer of the lamina propria, and the deep paraglandular layer of the mucosa. In general, we found that MMP-2, MMP-9, and TIMP-1 values were higher in the nasal polyp group. These differences became less so as patients' ages and the duration of polyps increased. We conclude that the most important role that MMP-2 plays in polyp growth may be in terms of perivascular localization and an increase in vascular permeability, which causes inflammatory cell migration and edema in the extracellular matrix. An increase in MMP-2 in glandular tissue may lead to hydrolysis of tissue matrix components. The degraded extracellular matrix may result in fibrosis of the polyps. An increase of MMP-9 in the apical part of the epithelium in the polypoid tissue of the nasal cavity, maxillary sinus, and ethmoid sinus may facilitate the epithelial and endothelial cell migration that is observed during polyp development and growth.

Most polyps in the nasal cavity develop from the mucosa of the anterior ethmoid sinus, the contact areas of the uncinate process, and the middle turbinate so that they are observed in the middle meatus.

Eosinophilic otitis media is refractory to conventional therapy for otitis media and may lead to severe hearing impairment if not recognized promptly.

Unusual presentations of choanal polyps: Report of 3 cases

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

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 the sphenoid sinus and the lateral wall of the nose. These polyps usually present unilaterally, although bilateral presentations are possible. We describe 3 cases of atypical choanal polyps: a sphenochoanal polyp, bilateral antrochoanal polyps, and a giant antrochoanal polyp. In each case, nasal endoscopy and computed tomography clinched the diagnosis, and endoscopic surgery was performed to successfully remove the polyp. We discuss the clinical characteristics of these 3 cases.

Laryngeal tuberculosis: Use of videostroboscopy in diagnosis

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

Nodules usually affect the anterior to middle thirds of the true vocal folds, and they are nearly always bilateral.

A case of a nasal polyp originating in the cribriform plate

article

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 a case of a nasal polyp that originated in the cribriform plate, which is a very rare site of origin for a nasal polyp.

The main symptom of a choanal polyp is unilateral nasal obstruction. Most of these masses arise from the maxillary sinus.

Endoscopic view of ostial polyps of the maxillary sinus

June 11, 2013     Dewey A. Christmas, MD; Joseph P. Mirante, MD, FACS; and Eiji Yanagisawa, MD, FACS
article

Ostial polys in the maxillary sinus can cause recurring maxillary sinus disease by obstructing the ethmoid infundibulum and natural ostium of the maxillary sinus.
