the objective of this study was to investigate the effect of intranasal phototherapy on nasal microbial flora in patients with allergic rhinitis. this prospective, self-comparised, single blind study was performed on patients with a history of at least two years of moderate-to-severe perennial allergic rhinitis that was not controlled  by  anti-allergic drugs.  thirty-one  perennial  allergic r...

OBJECTIVES Although the mechanisms underlying the initiation and maintenance of inflammation in unilateral maxillary fungal balls (FBs) are poorly understood, the relationship between intranasal anatomy and maxillary FB is thought to play an important role. The aim of this study was to investigate the relationship between anatomic variations and FB. METHODS We enrolled 140 patients who were c...

OBJECTIVE To evaluate whether a nasal gel, administrated using a radial-hole inhaler, reaches the olfactory cleft and if a different administration method influences distribution. MATERIAL AND METHOD Sixteen healthy volunteers underwent a nasal endoscopy at 1 and 7minutes after the administration of a intranasal gel, with a different method in each fossa. RESULTS No dye deposition was ident...

Cost-effective and feasible methods for early diagnosis of Alzheimer's disease (AD) are needed. We present two methods to measure AD-related biomarkers simultaneously from one nasal smear for the purpose of diagnosing AD. Japanese men and women aged 63-85 years old were recruited in 2015-2016 for this case-control study. A total of 25 AD cases and 25 controls (22 men and 28 women) participated ...

BACKGROUND Microbes and allergens can stimulate the nasal mucosa, potentially leading to the development of acute bacterial rhinosinusitis (ABRS). This study was designed to determine if allergen exposure alters the sinonasal microbiome. METHODS We performed a parallel observational study of healthy adults with seasonal allergic rhinitis (SAR; grass or tree, n = 20) or nonallergic subjects (n...

The lacrimal drainage system consists of the puncta (upper and lower within the eyelids) which are the opening to the upper and lower canaliculus. These meet at the common canaliculus and open into the lacrimal (tear) sac. This runs parallel to the nose and is separated from the middle meatus of the nasal cavity by two thin plates of bone. It continues down to become the nasolacrimal duct (tear...

BACKGROUND The aim of this retrospective investigation was to evaluate the position of the nasotracheal tube in the nose and to show its anatomical relationship with the maxillary sinus ostium. METHODS Fifty data sets from patients who had undergone endonasal intubation were analyzed for tube positioning. There was a drop-out of eight data sets due to missing information concerning tube size ...

OBJECTIVE Nasal endoscopy is integral to the evaluation of sinonasal disorders. However, prior studies have shown significant variability in the interrater agreement of nasal endoscopy interpretation among practicing rhinologists. The objective of the current study is to evaluate the interrater agreement of nasal endoscopy among otolaryngology residents from a single training program at baselin...
