In a rabbit model, MeroGel and FloSeal appear to increase reactionary fibrosis of healing mucosa. These agents also appear to be incompletely resorbed and grossly incorporated into healing tissue. Mucosal healing may be impaired by the application of these agents.
In a rabbit model, topical vitamin A in the form of retinoic acid gel appears to enhance regeneration of ciliated paranasal sinus mucosa. This preliminary study suggests that topical retinoids may have applicability in promoting sinus wound healing.
Complications related to the use of image-guided systems in sinus surgery are fortunately rare. We report a case series of 6 patients who experienced facial neuropathies (both sensory and motor) related to the use of a headset for electromagnetic-based image-guided surgery. The auriculotemporal nerve was the most common sensory nerve involved, and the buccal branch of the facial nerve was implicated in a case of motor weakness. The cause of the complication appears to be a pressure neuropathy caused by a tight-fitting headset against the external auditory meatus and temporomandibular joint. Additional risk factors for headset-related neuropathy may relate to body habitus, length of surgical procedure, and patient positioning. All patients' neuropathies resolved completely without intervention. Headset-related complications appear to be uncommon but may be an important consideration in counseling patients who are candidates for image-guided sinus surgery.
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.
