Acoustic Airway Profiles in Unilateral Cleft Palate Patients
1999
Objective: This study investigates the nasal airway in unilateral cleft palate patients by means of a noninvasive, objective diagnostic method that provides topographic information about the airway profile. Design: A consecutive sample of patients was measured. Setting: Cleft palate rehabilitation center of the University of Mainz, Germany. Patients: Forty-nine subjects were investigated: 34 full-grown patients with complete unilateral cleft lip and palate and 15 controls with subjective normal nasal patency. Intervention: A transnasal series of three acoustic measurements of nasal volume was performed per nostril; measurements were taken both before and after decongestion with 0.3 mg xylom…
Transcriptome Analysis Identifies Doublesex and Mab-3 Related Transcription Factor (DMRT3) in Nasal Polyp Epithelial Cells of Patients Suffering from…
2021
Background: Aspirin-exacerbated respiratory disease (AERD) is a syndrome characterised by chronic rhinosinusitis, nasal polyps, asthma and aspirin intolerance. An imbalance of eicosanoid metabolism with anover-production of cysteinyl leukotrienes (CysLTs) has been associated with AERD. However, the precise mechanisms underlying AERD are unknown. Objective: To establish the transcriptome of the nasal polyp airway epithelial cells derived from AERD patients to discover gene expression patterns in this disease. Methods: Nasal airway epithelial cells were isolated from 12 AERD polyps and 8 AERD non-polyp nasal mucosa samples as controls from the same subjects. Utilising the Illumina HiSeq 2500 …
Nasal airway, lip competence, and craniofacial morphology
1993
The aim of the present investigation was to demonstrate whether children selected by their open lip posture show differences in their nasal airway resistance and facial morphology compared to children with closed lip closure. Thirty-two children with poor lip competence were compared to a control group of 20 with secure mouth closure. Patients with poor lip competence showed a significantly higher ML-NSL angle and also ML-NL angle. Anterior rhinomanometry, as well as measurements of the pharyngeal space on lateral headfilms, displayed no significant differences between the two groups. The same material was also grouped cephalometrically into skeletal open and skeletal deep bite configuratio…
Veränderungen des nasalen Atemwegs durch transversale Distraktion des Oberkiefers
1999
Fragestellung: In dieser Untersuchung sollten die Auswirkungen der transversalen Distraktion des Oberkiefers auf den nasalen Atemweg durch ein nichtinvasives Untersuchungsverfahren beschrieben werden. Es wird damit untersucht, ob die chirurgische Gaumennahterweiterung eine Weitung auch der posterioren Oberkieferbasis erreicht und durch Vergroserung des Nasenklappenquerschnitts eine Normalisierung der nasalen Ventilation gelingen kann. Material und Methode: Bei 8 Patienten mit hochgradigem Schmalkiefer wurde eine transversale Distraktion des Oberkiefers vorgenommen. Vor der Osteotomie und nach Abschlus der Distraktion wurde das Querschnittprofil des nasalen Atemwegs unter lokaler Schleimhaut…
