INTRODUCTION An Antrochoanal polyp, or Killian's polyp is a benign solitary polypoid lesion that affects mainly children and young adults. Studies demonstrate that Killian's polyp generally represents 4-6% of all nasal polyps. However, in the pediatric population this percentage reaches 33%. It originates from a hypertrophy of the mucous membrane on the maxillary sinus antrum, and it grows for ...

Nasal Polyposis (N.P) is not simply mucosa oedema, but rather grape shaped, smooth, soft, freely mobile mucosal swellings that are often visible on anterior rhinoscopy. Polyps arise from the lateral wall of nose. N.P. may be present without clinically significant sinus disease and vice versa. In Ayurveda, polyposis can understood with Nasa Arsha. Modern management includes antibiotic, systemic ...

PURPOSE Chronic rhinosinusitis with nasal polyps is a chronic inflammatory disease with markedly increased eosinophils, Th2-type lymphocytes, fibroblasts, and goblet cells. Fungi are commonly associated with airway inflammatory diseases, and thymic stromal lymphopoietin (TSLP) is important in the development of Th2 inflammatory responses. The aim of this study was to investigate the interaction...

Antrochoanal polyps usually present unilaterally. It is defined as a polyp originating in the maxillary sinus, protruding in the middle meatus through the ethmoidal infundibulum or an accessory ostium and further extends posteriorly through the choana into the nasopharynx or in oropharynx in a few cases. An antrochoanal polyp usually has three parts according to its extension, i.e antral, nasal...

BACKGROUND/AIM Chronic sinusitis is a disease characterized with mucosal inflammation of nasal and paranasal sinuses for at least 12 weeks. In order to assess the extent and severity of inflammatory changes in paranasal sinuses CT score according to Lund-Mackay is the most commonly used. Recent studies show the possibility of existing different subtipes of chronic rhinosinusitis, pointing out t...

Nasal polyp is one of the common causes of nasal obstruction. The diagnosis is usually made on clinical ground and rarely needs histological examination. However, when a candidate is selected for the surgical option of polyp removal, there is tendency to send all specimens for routine histological examination. The objective of this study was to assess the necessity of routinely performed histol...

Inflammatory cell populations have not been yet precisely evaluated in cystic fibrosis (CF) airways. We intended to characterize morphological modifications, inflammatory cell infiltration and cell proliferation in nasal tissues obtained from 15 CF patients and from 6 non-CF patients with nasal polyposis. Morphological analysis showed an intense inflammatory infiltration in CF and non-CF tissue...

BACKGROUND/AIMS The aim of this study was to evaluate the efficacy of high definition (HD) i-SCAN for colorectal polyp detection in screening colonoscopy. METHODS We retrospectively analyzed the records of 501 patients who had undergone screening colonoscopy performed by three endoscopists with either HD i-SCAN (n=149) or standard white light (n=352) from January 2, 2014 through June 30, 2014...

was an accidental observation when the patient went to the doctor for some other condition. Surprisingly, less than 10% of the patients went actually complaining of a change in their appearance, but this reflects the very slow way in which the condition usually evolves. Most of the other presenting symptoms were due to local spread of the tumour or to recognised features or complications of acr...

background: nasal inflammatory disorders such as chronic rhinosinusitis and nasal polyp are among the most prevalent complications with high socioeconomic costs. vascular endothelial growth factor (vegf) plays a key role in angiogenesis and cell proliferation. in the present study the effect of vegf on the development and prognosis of chronic rhinosinusitis and nasal polyp was investigated. met...
