GOALS To give an overview on the theoretical and practical applications of chemosensory event-related potentials. METHODS Chemosensory event-related potentials (ERPs) may be elicited by brief and precisely defined odorous stimuli. Based on the principles of air-dilution olfactometry, a stimulator was developed in the late 1970s, which allows stimulation(More)
Juvenile angiofibroma (JNA) is a rare benign but locally aggressive tumour of the nasopharynx that primarily occurs in adolescent males. We report a series of 6 consecutive cases operated by exclusive endoscopic approach between from March 1996 and June 2003. All were male. The mean age was 17.2 years old (range: 11-23 years). The tumour involved the(More)
Thornwaldt's cyst is a relatively rare lesion located in the posterior wall of the nasopharynx. Most are small and asymptomatic whereas some cause nasal obstruction, postnasal drip, occipital headache or Eustachian tube dysfunction. Nasal endoscopy is the easiest way to visualize this during a routine ENT examination. If in any doubt, MRI is the most(More)
OBJECTIVES ENT surgeons are facing an ever-increasing demand to demonstrate their efficacy. The 22-item Sino-Nasal Outcome Test (SNOT-22) is a fully validated and easy-to-use outcome measure in rhinology. Our goal was to translate and validate the SNOT-22 in a cohort of 422 French-speaking subjects. DESIGN, SETTING AND PARTICIPANTS The French version of(More)
OBJECTIVES Post-traumatic olfactory loss (PTOL) is the third most common aetiology for olfactory disorders. Mechanisms that lead to post-traumatic olfactory disorders include sinonasal affections, damage to the olfactory nerve and lesions of the cerebral olfactory centres. The purpose of this review is to present an update of this condition and to present a(More)
BACKGROUND Little is known about the genetic factors that contribute to nasal polyposis (NP). A genome-wide association study identified 10 single nucleotide polymorphisms (SNPs) associated with eosinophilia. As eosinophils play a key role in the pathogenesis of NP, we assessed if any of these SNPs contribute to genetic susceptibility of NP. METHODS We(More)
Draf in 1991. The procedure--which is also known as the modified endoscopic Lothrop procedure--aims to create the largest possible anteroposterior and lateral to lateral opening between both frontal sinuses and the nasal cavities. This requires the resection of the medial floor of both frontal sinuses, the intersinus septum and the superior nasal septum.(More)
Sleep disordered breathing (SDB) patients usually undergo an ENT clinical examination before any therapeutic decision. This clinical examination would be predictive about the occurrence of Obstructive Sleep Apnea Syndrome, cost effective, reproducible and would determine the sites of obstruction in the upper airways. To achieve this, ENT specialists from(More)
AIM OF THE STUDY To assess the validity of transcanalicular diode laser assisted dacryocystorhinostomy (TLADCR) in the treatment of distal obstruction of the lachrymal pathways. MATERIAL AND METHOD Between June 1999 and February 2000, 29 TLADCR were performed in the ENT department on 26 patients. Surgical indications included chronic dacryocystitis in 19(More)
