RESULTS : In total, 37 dogs were included in the sacculectomy group and 44 in the comparator group. Dogs that had undergone sacculectomy were more likely to develop postoperative complications, with 18 of 37 developing complications, nine of which were moderate to severe. In the group without sacculectomy, nine of 44 dogs developed complications, of which one was severe. Different breed distribution between groups might also impact this outcome.CLINICAL SIGNIFICANCE : The results suggest that sacculectomy might increase morbidity following brachycephalic airway surgery, but repeat studies are required to confirm this result. Further information is also required to determine whether the short-term risks of sacculectomy are outweighed by superior long-term functional outcome.
This is a retrospective review of benign cysts of the adult endolarynx that presented as airway emergencies in four teaching hospitals of Dublin, Ireland, over 2 years. During that period nine patients with endolaryngeal cysts necessitating emergency airway intervention were managed. All cases were treated by endoscopic microlaryngeal marsupialization after securing the airway either at the same time or as a staged procedure. Four of these patients required tracheostomies, one performed under local anaesthesia and the others after initial endotracheal intubation. Definitive treatment was carried out in six cases at initial endoscopic diagnosis. Three of the tracheostomized patients had a staged management, two because of their medical status and one for further investigations. On the basis of our findings we suggest that all benign cysts around the endolarynx should simply be called 'endolaryngeal cysts' instead of the current practice of trying to classify them into various histological and morphological types with no prognostic or management differences. Benign cysts of the endolarynx presenting with airway obstruction would appear to be more frequent than is generally maintained in the literature.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
