Collision tumors are exceptional, associating two independent tumoral contingents. We report a case of an association of two rare tumors: sinonasal adenocarcinoma and chondroid chordoma. Initially, only adenocarcinoma was diagnosed. The treatment consisted of endoscopic endonasal surgery followed by conventional radiotherapy. After 18 months, a local recurrence was diagnosed after a facial trau...

Silent sinus syndrome (SSS) is a rare and interesting clinical condition that is associated with spontaneous, painless, unilateral enophthalmos and hypoglobus resulting from downward bowing of the orbital floor, in the absence of any symptomatic sinonasal disease. It generally affects younger patients between the third and fifth decades of life. The pathogenesis of silent sinus syndrome is base...

A 38-year-old male came to outpatient clinic, presenting with a 1-month history of headache and right facial pain. There was no specific finding on nasal endoscopy. Paranasal sinuses computed tomography (PNS CT) showed unilateral soft tissue density maxillary sinus ground glass opacity zygomatic bone. And there suggestive malignancy in the subsequent PNS magnetic resonance imaging (MRI). We con...

OBJECTIVES/HYPOTHESIS Bleeding during endoscopic sinus surgery and open surgeries can easily obstruct the surgeons' field of view and increase morbidity and risk of intraoperative complications. Intraoperative bleeding could potentially be addressed by a hemostatic agent that safely disperses itself through the escaping blood. We tested the safety and efficacy of a self-propelling formulation o...

Endoscopic surgery is performed on patients with chronic inflammatory disease of the paranasal sinuses to improve sinus ventilation. Little is known about how sinus surgery affects sinonasal airflow. In this study nasal passage geometry was reconstructed from computed tomographic imaging from healthy normal, pre-operative, and post-operative subjects. Transient air flow through the nasal passag...

This is the official guideline endorsed by the specialty associations involved in the care of head and neck cancer patients in the UK. With only limited high-level evidence for management of nasal and paranasal sinus cancers owing to low incidence and diverse histology, this paper provides recommendations on the work up and management based on the existing evidence base. Recommendations • Sinon...

OBJECTIVE We report the use and benefits of the ultrasonic dissector in the resection of difficult skull base lesions. METHOD Five case reports are presented, and the utilisation of ultrasonic dissectors in otorhinolaryngology is reviewed. RESULTS The ultrasonic dissector was found to be a useful tool during the endoscopic resection of poorly accessible skull base tumours. Safe dissection a...

Introduction: Bioabsorbable steroid-eluting implants are available as an adjunct for endoscopic sinus surgery (ESS) in the treatment of chronic rhinosinusitis (CRS). It is unclear which patients are most likely to benefit from this technology. We sought to determine if the severity of preoperative sinonasal inflammation influences the postoperative changes in patient-reported quality of life (Q...

OBJECTIVE To use combined pre- and postsurgical olfactory outcomes to assess the impact of endoscopic sinus surgery on chronic rhinosinusitis-related olfactory impairment. DATA SOURCES CINAHL, Cochrane, OVID, EMBASE, PubMed, and SCOPUS. Each database was searched from inception up to October 2015. REVIEW METHODS Studies were included that reported subjective or objective olfactory data in c...
