Although choanal polyps frequently arise from the maxillary sinus, a choanal polyp originating from the inferior turbinate is a rare entity. A 14-year-old girl who had a history of bilateral nasal obstruction with snoring, mouth breathing and nasal discharge for 10 years was presented. On endoscopic examination, a polypoid mass completely obliterated the right nasal cavity. The left choana was ...

randomized to therapy with linezolid. Therefore, we think that the conclusion that linezolid “is associated” with lower mortality rates and greater clinical success rates than vancomycin in patients with MRSA pneumonia is valid. We, as the nonemployee authors of these manuscripts, and many other clinicians who have been presented these data have raised the same concerns about subgroup analysis ...

The immediate responses of the upper respiratory tract (URT) to the irritants acrolein and acetic acid were examined in healthy and allergic airway-diseased C57Bl/6J mice. Acrolein (1.1 ppm) and acetic acid (330 ppm) vapors induced an immediate increase in flow resistance, as measured in the surgically isolated URT of urethane-anesthetized healthy animals. Acrolein, but not acetic acid, induced...

Introduction: Chronic nasal obstruction due to adenoid hypertrophy is a very common disorder. Although the clinical assessment of adenoid hypertrophy is essential, its real value in young children is difficult to evaluate. The purpose of this prospective study was to validate a simple clinical score to predict the severity of adenoid obstruction and to evaluate the relationship between this met...

OBJECTIVE To investigate effects of the nose dilating devices on nasal anatomy and breathing in healthy subjects. MATERIALS AND METHODS 27 healthy subjects were tested when using the Breathe Right nasal strip or the Nozovent dilator. Posterior rhinomanometry, acoustic rhinometry, and a subjective evaluation were used as methods. RESULTS Both devices significantly increased the minimum cross...

Case Description- A 25-year old, mare, Arab horse presented to department of surgery of veterinary hospital of Shahid Chamran university of Ahvaz with the signs of breathing disorder, snoring, localized infections of the nose in the right nostril. Clinical Findings- Physical examination revealed a mass in the nasal vestibule which attached to the septum and caused partial obstruction of the nas...

This study verified the influence of chronic mouth breathing on dentofacial growth and developmental in pre-school children. The study evaluated 73 children, both sexes, ranging from 3 to 6 years of age. After the otorhinolaryngological breathing diagnosis, 44 mouth-breathing children and 29 nasal-breathing children were compared according to facial and occlusal characteristics. The skeletal pa...

In 20 normal and four anosmic participants, instantaneous inhalation and exhalation flow rates were recorded in response to 15 s stimulations with clean air or propionic acid concentrations (0.16, 1.14, 8.22 and 59.15 p.p.m., v/v) that ranged from peri-threshold for normals to clearly supra-threshold for anosmics. Each odorant/irritant delivery to the face-mask began with an exhalation. This al...

BACKGROUND Sleep-disordered breathing in general and obstructive sleep apnea in particular are commonly encountered conditions in allergy practice. Physiologically, nasal (or nasopharyngeal) obstruction from rhinitis, nasal polyposis, or adenotonsillar hypertrophy are credible contributors to snoring and nocturnal respiratory obstructive events. Nevertheless, existing practice parameters largel...
