Nasal respiratory turbinate function in birds.
Nasal respiratory turbinates are complex, epithelially lined structures in nearly all birds and mammals that act as intermittent countercurrent heat exchangers during routine lung ventilation. This study examined avian respiratory turbinate function in five large bird species (115-1,900 g) inhabiting mesic temperate climates. Evaporative water loss and oxygen consumption rates of birds breathin...
متن کاملRecovery of respiratory ciliary function after depression by inhalation anaesthetic agents: an in vitro study using nasal turbinate explants.
We have developed a human tissue preparation suitable for measurement of cilia beat frequency derived from nasal turbinates. Cilia beat frequency of turbinate explants from 11 patients did not change significantly over a 10-day observation period while maintained in an incubator, with mean cilia beat frequency of 13.1 (SEM 0.3) Hz to 14.4 (0.2) Hz (ANOVA for repeated measures, P = 0.168). We ha...
متن کاملNasal, septal, and turbinate anatomy and embryology.
This article discusses the development and anatomy of the nasal septum and structures of the lateral nasal wall. Emphasis is placed on anatomic variations associated with surgically correctable nasal obstruction. Common variations, such as deviated nasal septum, inferior turbinate hypertrophy, paradoxic middle turbinate, and concha bullosa, are discussed. Rare developmental causes of nasal obst...
متن کاملInferior turbinate flap for repair of nasal septal perforation.
INTRODUCTION Many surgical techniques are available for surgical repair of nasal septal perforations. The variety of techniques is evidence that no single technique is recognized as being uniformly reliable in closing all perforations. In fact, most perforations remain unclosed because available closure techniques are technically difficult and require training and experience to master. Many aut...
متن کاملEfficacy of inferior turbinate coblation for treatment of nasal obstruction.
OBJECTIVE To determine the efficacy of inferior turbinate coblation for the treatment of nasal obstruction. METHODS Twenty patients awaiting submucosal diathermy to the inferior turbinates were recruited into the study. All underwent inferior turbinate coblation. Pre-operative and post-operative nasal function was investigated using posterior rhinomanometry and subjective symptom scales. RE...
