Cysteinyl leukotriene 1 receptor expression in nasal polyps.

Cysteinyl leukotrienes (CysLTs) have been implicated in the pathogenesis of chronic rhinosinusitis (CRS). This study was undertaken to better understand the role of CysLTs in the development of CRS through 1). assessment of the pattern of expression of CysLT1 receptor in nasal polyps from patients with CRS and 2).

Haemangiopericytoma-like tumor of the nasal cavity treated by endoscopy - a case report.

Haemangiopericytoma (HPC) is an uncommon, vascular tumor derived from Zimmerman pericytes surrounding blood vessels. HPC constitute around 1% of all tumors of vascular origin and may appear anywhere, 5% of them can be situated in nasal cavity. Tumor location within the head and neck predispose to its benign character and improves prognosis.

Evaluation of fully biodegradable nasal packings in functional endoscopic sinus surgery – a multi-centre study.

The Aim: This work was to compare an innovative solution, i.e. a fully biodegradable nasal packing Nasopore®, with a traditional one, in the aftercare of patients subjected to functional endoscopic sinus surgery.

Endoscopic drainage of orbital abscesses aided with intraoperative sonography.

Background And Purpose: Accurate localization and adequate visualization of the superiorly or inferiorly located subperiosteal orbital abscesses or intraorbital abscess is difficult with transnasal endoscopic approach. Sonography is a well-known and effective tool for evaluation of orbital pathologies but no paper documenting intraoperative application of this method in orbital abscess surgery has been published to date.

Material And Methods: We present a series of 12 patients in whom orbital abscesses were drained endoscopically with an aid of neuronavigation and intraoperative ultrasonography.
