Various types of implants are being commonly used for monitoring vital signals and controlling the critically ill patient's condition such as arrhythmia, sick sinus syndrome, etc. For implanting these medical devices under the skin, surgery is inevitable. These days many patients are more willing to accept interventional therapies that are less invasive, especially inserting a catheter into a blood vessel or endoscopy through a natural orifice. To be able to use interventional therapy for implanting medical devices, they will need to be small enough to fit them through a catheter or the forceps channel of an endoscope...

The retro- and hypotympanum are hidden areas of the middle ear, only poorly recognized. Nevertheless, this region is of relevant clinical significance, since it is regularly affected by disease such as cholesteatoma. The aim of this study is to explore and describe the anatomical variants of the hypo- and retrotympanum by the means of transcanal endoscopy. We hypothesize a significant variability of this hidden region of the middle ear. Moreover, we believe that the minimal invasive, endoscopic access is suitable since angled scopes may be used to explore the region...

Esthesioneuroblastoma is a rare malignant neoplasm of oflactory neuroepithelium and usually located at the olfactory cleft at superior nasal cavity. Ectopic localization of esthesioneuroblastoma is even rarer and usually posed with a diagnostic dilemma and delay in the diagnosis and management, We report a rare case of ectopic esthesioneuroblastoma of the sphenoclivus with the presentation of intermittent unilateral epistaxis, intermittent intractable headache without anosmia. Nasal endoscopy findings showed a pulsatile mass at the anterior face of the sphenoid sinus with extension posteriorly towards the clivus region and occupying the floor of the sphenoid sinus...

The united airways concept suggests that patients with asthma typically exhibit parallel inflammation in the upper airway. The resulting nasal symptoms should reduce quality of life and substantially affect the evaluation of asthma control among these patients. This study aimed to assess the association of nasal symptoms with the evaluation of asthma control.Fifty-eight patients with asthma and persistent nasal symptoms were prospectively recruited for evaluations of their sinonasal symptoms and asthma control in a cross-sectional study from August 2013 to June 2016...

BACKGROUND: Benign tumors of the nasal cavity represent a large variety of different histopathological entities. Although advances in nasal endoscopy over the past couple of decades have made it possible to detect the vast majority of these lesions, accurate diagnosis and proper management can be delayed since they are misdiagnosed as inflammatory paranasal sinus disease or simple epistaxis. OBJECTIVES: The aims of the present study are to determine the relative incidence of benign tumor of the nasal cavity and to provide typical endoscopic features of common tumors...

Aims. In order to determine the indications of transoral surgery for a tumor located at the pharyngoesophageal junction, the trumpet maneuver with transnasal endoscopy was used. Its efficacy is reported here. Material and Methods. An 88-year-old woman complaining of dysphagia, diagnosed with cervical esophageal cancer, and hoping to preserve her voice and swallowing function was admitted to our hospital. Conventional endoscopy showed that the tumor had invaded the hypopharynx. When inspecting the hypopharynx and the orifice of the esophagus, we asked the patient to blow hard and puff her cheeks with her mouth closed (trumpet maneuver)...

Meningiomas are common intracranial neoplasms but extracranial meningioma of the paranasal sinus is extremely rare. The recommended treatment of these meningothelial tumors is complete surgical excision. The authors report a 79-year-old woman presenting with facial pain and nasal obstruction for several months. Endoscopic nasopharyngeal examination showed a right nasal mass that arose from the nasopharynx and reached around the middle meatus. Gadolinium-enhanced magnetic resonance imaging showed a well-circumscribed nasopharyngeal mass, which originates from the right rosenmuller fossa and extends to the right nasal cavity...

Primary sinonasal/nasal tuberculosis is rare amongst the commonly seen cases of extrapulmonary tuberculosis. We report three cases, two of primary sinonasal tuberculosis and one case of nasal tuberculosis in otherwise healthy patients. The diagnosis was based on radiological and histopathological findings. Treatment with antitubercular drug therapy was successful in all three of them. Sinonasal region tuberculosis, despite its rarity, should be added to differential diagnosis of nasal and paranasal sinus disorders particularly with intractable symptoms...

An otherwise healthy 34-year-old man was referred to our ear, nose and throat (ENT) clinic for a bilateral maxillary radiologic opacity. This condition was accidentally discovered with a panoramic radiography performed during a follow-up visit after a bilateral endodontic treatment. The patient did not report any specific sinonasal symptom such as purulent nasal discharge, loss of smell and cough, apart from an unspecific sinus pressure. The CT scans showed a bilateral inflammatory process into the maxillary-ethmoidal sinuses and an iron-like density within the maxillary sinuses, while nasal endoscopy showed purulent discharge in the ostiomeatal complex...
