PURPOSE Paranasal sinus mucocele is a benign, expansile mass which can occur as a result of trauma or spontaneous obstruction of a sinus tract. The purpose of this study was to describe and compare the clinical characteristics of primary mucoceles occurring in patients with no previous sinus surgery history or known cause of mucoceles and secondary mucoceles resulting as a complication followin...

PURPOSE To investigate the long-term follow-up outcomes of nonlaser intranasal endoscopic dacryocystorhinostomy (IEDCR) using a nasal endoscope and conventional surgical instruments available in all operating rooms, the advantages of this technique, and the usability and suitability of conventional instruments. METHODS Twenty-seven IEDCRs were performed in combination with bicanalicular silic...

<p class="abstract">Nasal lobular capillary hemangioma (LCH) is a rare and benign vascular tumor of unknown etiology, often associated with hormonal factors history trauma. In this case series we present twelve cases nasal LCH diagnosed on patients treated at the Hospital da Senhora Oliveira from January 2010 December 2019. Of 12 patients, 66, 7% were males. The most common clinical prese...

A not pregnant 4-year-old Jersey cow was presented with the sudden appearance of respiratory noise, nasal discharge and moderate respiratory difficulty. Upon physical examination a snoring-like noise, extended head and neck position, exaggerated abdominal effort, bilateral nasal discharge and left prescapular lymph node enlargement were noted. Sub-occlusion of the initial portion of the respira...

Chronic rhinosinusitis (CRS) is defined as chronic inflammation of the nose and paranasal sinuses with two or more symptoms, one which can be nasal congestion/obstruction/congestion rhinorrhea (anterior/postnasal drip), and/or facial pain, reduced loss smell. Elongated uncinate anatomical variants process where curved bent, causes sinus problems risk factors for CRS. It has been reported a 19-y...

BACKGROUND Fungal infections of the nasal cavity can be destructive entities that are typically seen in immunocompromised hosts. We present a case of a localized fungal abscess of the nasal septum in an immunocompetent host after endoscopic treatment of maxillary sinus fungus balls. METHOD A 51-year-old woman with a history of asthma and recent treatment with oral steroids presented with bila...

BACKGROUND There is a need to find an animal model to study new medications to improve mucosal wound healing after functional endoscopic sinus surgery (FESS). Current literature suggests swine as a potential candidate. The lack of information correlating swine computer tomography (CT) and endoscopic sinonasal anatomy prompted us to investigate them in the domestic and Yucatan swine to determine...

Asian people frequently show small noses, narrow nasal apertures, and congestive mucosa on the turbinates and septum. To reduce the risk of nasal morbidity with increased radicality for skull base tumors in these patients, we developed endoscopic transnasal interseptal approach (ETISA) in transsphenoidal surgery for invasive clival tumors (ICTs). Indication for ETISA is radical resection for tu...

OBJECTIVE To determine whether the 15-degree reverse Trendelenburg position (RTP) during functional endoscopic sinus surgery improves endoscopic field of view and reduces intraoperative blood loss when compared with the horizontal position (HP). STUDY DESIGN A prospective, randomized controlled trial. SETTING St Paul's Sinus Centre, Vancouver, Canada. SUBJECTS Patients with chronic rhinos...
