Introduction: Following nasal surgery, temporary eustachian tube dysfunction is a common problem due to nasal packing.Therefore we aimed to compare the effects of PosiSep®X and silicone nasal septal splints with integral airway on the ventilation and the pressure of the middle ear after septoplasty in patients with normal otoscopic examination.

Methods: Between June 2021 and September 2022, patients who underwent septoplasty for nasal septal deviation with otoscopically normal tympanic membranes and bilateral normal type A pre-operative tympanograms were included. Following surgery patients were randomized into two groups (Group P: Chitosan-based biodegradable nasal packs. Group S: Silicone nasal septal splint group). Nasal packs and septal splints were removed at second day following surgery. The middle ear pressure (MEP) was measured using tympanometry pre-operatively. Following surgery, tympanometry was repeated at 24 hours and just before the removal of nasal packs on the second day, and finally on the 7th post-operative day.

Results: Both groups comprised of 30 patients each. There were no statistically significant difference between two groups in terms of age and gender (p=0,33; p=0,605 respectively).
Both groups comprised of 30 patients each. Tympanometric pressures of all patients decreased in both groups, but more so in group S in the first 24 hours following surgery. After 24 hours, MEP started to increase in both groups furthermore, it reached almost preoperative values by the 48th hour in group P (p=0,001). All MEPs returned to preoperative values by the 7th postoperative day for both groups except 1 patient of group S

Conclusions: Temporary aural fullness and eustachian dysfunction which leads to patients discomfort and dissatisfaction due to nasal packings after septoplasty is a common problem. Our study demonstrated that PosiSep®X caused less eustachian dysfunction than silicone nasal splint with integral airway. As well as leading to less eustachian dysfunction, PosiSep®X does not require removal. Therefore, we think it would be a good alternative for nasal packing after septoplasty.
