BACKGROUND Nasal airway obstruction (NAO) is a common health condition impacting mood, energy, recreation, sleep, and overall quality of life. Nasal surgery often addresses NAO but the results are sometimes unsatisfactory. Evaluating surgical treatment efficacy could be improved if objective tests were available that correlated with patient-reported measures of symptoms. The goal of this study ...
OBJECTIVE To measure the efficacy of a specific midvault reconstruction technique (the autospreader flap) in dorsal reductive rhinoplasty with a validated quality-of-life instrument. DESIGN A prospective observational outcomes study of patients desiring reduction of the nasal dorsum who either (1) had no breathing obstruction, who underwent purely aesthetic rhinoplasty, or (2) had concomitant...
BACKGROUND Nationwide epidemiologic data on rhinitis in the elderly do not exist. This study aimed to estimate the prevalence of rhinitis in the population aged 65 years or above in mainland Portugal and to characterize and classify rhinitis in this age group. METHODS Cross-sectional, nationwide, population-based survey of citizens aged 65 years or above, living in mainland Portugal. Current ...
PURPOSE The purpose of this article is to determine whether certain facial asymmetries (nose and chin) have an impact on the perception of the maxillary dental midline shift. MATERIALS AND METHODS From a digitally created symmetric facial model (SFM) constructed in a previous study, a new asymmetric facial model (AFM) was created, with nose and chin deviated to the same side. Modifications we...
BACKGROUND Nasal valve collapse is a common cause of nasal obstruction in otolaryngology practice. Common examination methods, such as the Cottle Maneuver and modified Cottle Maneuver are available. However, these methods are dichotomous and do not provide ordinal severity information. The Ottawa Valve Collapse Scale (OVCS) is a grading system for assessing and easily grading external nasal val...
INTRODUCTION Crooked or deviated nose is a deviation of the nose from the straight vertical position of the face. Extensive pneumatization of the middle turbinate, also called concha bullosa or bullous middle turbinate (BMT) is known to be one of the possible etiologic factors in nasal obstruction, recurrent sinusitis, and headache. There is no study concerning a link between BMT and crooked no...
AbstractThis paper investigates a novel technique for extraction of the nose-tip from three-dimensional face image in any pose, which is needed for nose-tip based face registration. The present technique uses weighted median filter for smoothing. No normalization process is applied and the system correctly detects nose-tips across any pose variations. In our system, at first the range images ar...
BACKGROUND Nasal pyramid fractures accompanied by saddle nose deformities are not easily corrected by closed reduction. We used an absorbable plate as a perpendicular strut to support the collapsed "keystone area" and obtained good results. METHODS Between September 2008 and June 2011, 18 patients who had nasal pyramid fractures with saddle nose deformities underwent surgery. Pre- and postope...
Despite initial enthusiasm towards electronic noses and their possible application in different fields, and quite a lot of promising results, several criticalities emerge from most published research studies, and, as a matter of fact, the diffusion of electronic noses in real-life applications is still very limited. In general, a first step towards large-scale-diffusion of an analysis method, i...
A gas sensor array consisting of eight metal oxide semiconductor (MOS) type gas sensors was evaluated for its ability for assessment of the selected wastewater parameters. Municipal wastewater was collected in a wastewater treatment plant (WWTP) in a primary sedimentation tank and was treated in a laboratory-scale sequential batch reactor (SBR). A comparison of the gas sensor array (electronic ...
