Description of intervention(s) / exposure
The study involves the application of a solgel containing dexamethasone to previously opened sinus cavities. The solgel will be prepared at the Princess Alexandra Hospital in the Pharmacy department using techniques described by Pandey et al with blue food dye added to aid contrast between mucosal tissue.

Solgel consists of:
- Poloxamer 407 16% w/w
- Glycerin 3% w/w
- Propylparaben 0.03% w/w
- Polyvinyl alcohol 0.03% w/w
- Polycarbophil 0.02% w/w
- Dexamethasone 21-phosphate sodium salt 0.1% w/w
- water soluble blue dye

Participants will be recruited from Greenslopes Private hospital from the two supervising Otolaryngology Head and Neck (OHN) surgeons outpatients. They will be eligible if they are at least 6 weeks or more post endoscopic sinus surgery and had at least either their maxillary or ethmoid sinuses opened surgically. They will be approached at their postoperative follow up appointment by the treating consultant. If they are interested in participating in the trial will be contacted by the primary investigator to discuss the trial and obtain consent.

The trial will be conducted at the Princess Alexandra Hospital in the OHN surgery outpatient department. Each participant will receive three actuations (100 micrograms/actuation) of Co-phenylcaine nasal spray (ENT Technologies, Melbourne) to each nostril to anaesthetise and decongest the nasal cavity prior to solgel administration. Under direct vision using a rigid endoscope (Storz), solgel will be applied to the surgically opened sinus cavities of the maxilla and/or ethmoid and/or sphenoid sinus using a syringe device. A photo will be taken before and after the solgel application. All images taken throughout will be saved onto the Karl Storz system as a study number and transferred to an encrypted USB.

The maxillary sinus and/or sphenoid cavity will have 2 ml of solgel applied to the posterior wall while the ethmoid cavity will have 1ml applied. The cavities will be assessed again in 5 minutes with the rigid endoscope to assess the distribution. The patient will then be reviewed the following day and have their sinuses re-examined to assess for remaining gel. If the gel is still present, they will be reviewed again at day 5 to assess for the presence of the solgel.

Patients with diseased sinuses will have their sinuses graded independently by a sinus surgeon using the Modified Lund Mackay postoperative endoscopy score if they are assessed at the day 5 visit to assess for any improvement.
