From modeling to remodeling of upper airways: Centrality of hyaluronan (hyaluronic acid).

After traumatic events (accidental or surgical), the respiratory tract activates specific and prolix repairing mechanisms which tend to claw back the primitive differentiated state. The attempt of reactivation of the normal tissue functions is called 'remodeling' and its aim is to reinstate the modeling mechanisms that existed before the damaging event or the pathology's establishment. Endoscopic sinus surgery represents the gold standard treatment for inflammatory, malformative, benign, and, in selected cases, malignant diseases.

Bone regeneration after sinonasal mucocele marsupialization: What really happens over time?

Objective: To evaluate the necessity of reconstructing the eroded bony boundaries after mucocele marsupialization when the mucoperiosteum has been spared.

Study Design: Retrospective review of 308 patients treated for a sinonasal mucocele. Of these, 116 showed areas of bone reabsorption in their preoperative computed tomography (CT) scan.

Post-traumatic optic neuropathy: our surgical and medical protocol.

Post-traumatic optic neuropathy (TON) is a rare, but very much feared event. It is a traumatic injury of the optic nerve at any level along its course (often inside the optic canal), with partial or total loss of visual acuity, temporarily or permanently. Until now, an univocal treatment strategy does not exist.

Newly designed double-vascularized nasoseptal flap to prevent restenosis after endoscopic modified Lothrop procedure (Draf III): laboratory investigation.

Despite advances in endoscopic approaches, instrumentations and imaging guidance systems, the management of frontal sinus is still challenging. Failure of the endoscopic procedure and restenosis of the newly formed ostium have been demonstrated even with large frontal sinusotomy. We describe a newly designed double nasoseptal flap to cover the bare bone after endoscopic modified Lothrop procedure (EMLP).

Hyaluronan plus saline nasal washes in the treatment of rhino-sinusal symptoms in patients undergoing functional endoscopic sinus surgery for rhino-sinusal remodeling.

Hyaluronic acid is a major component of many extracellular matrices and plays a central role in the homeostasis of physiology in upper and lower airways. When topically administered following endoscopic sinus surgery, hyaluronic acid may be effective in functional recovery and in the prevention of recurrence of chronic rhinosinusistis. This pilot study was aimed at evaluating the effects of nebulised 9 mg of sodium hyaluronate given for 15 days per months over 3 months in 46 patients aged greater than 4 years who underwent functional endoscopic sinus surgery (FESS) for rhino-sinusal remodelling.
