OBJECTIVE: At present, endonasal paraseptal splints are devices frequently employed in rhinosurgery. We evaluated the local tolerance of a newly shaped device, the Guastella/Mantovani splint (G/M-SVS), with respect to the physiological mechanism of mucociliary clearance. STUDY DESIGN AND SETTING: The study involved 20 patients who underwent septoplasty and/or turbinoplasty or other nasal surgical procedures. A sample of ciliated cells was obtained by nasal brushing and was examined ex vivo to determine the ciliary beat frequency (CBF) and morphology, before and 15 days after surgery. RESULTS: Before surgery the mean CBF was 10.87 Hz ± 0.56 Hz and when splints were removed it was 10.25 Hz ± 1.9 Hz. Morphological evaluation of the ciliary motion after surgery demonstrated a normal, coordinated beat. CONCLUSIONS: The G/M-SVS does not appear to interfere with the physiological mechanism of mucocillary clearance since CBF remain within a normal range. SIGNIFICANCE: This is the first study that demonstrates an optimal tolerability and safety of the septo-valvular splints on nasal mucosa.

Abstract

OBJECTIVE: At present, endonasal paraseptal splints are devices frequently employed in rhinosurgery. We evaluated the local tolerance of a newly shaped device, the Guastella/Mantovani splint (G/M-SVS), with respect to the physiological mechanism of mucociliary clearance. STUDY DESIGN AND SETTING: The study involved 20 patients who underwent septoplasty and/or turbinoplasty or other nasal surgical procedures. A sample of ciliated cells was obtained by nasal brushing and was examined ex vivo to determine the ciliary beat frequency (CBF) and morphology, before and 15 days after surgery. RESULTS: Before surgery the mean CBF was 10.87 Hz ± 0.56 Hz and when splints were removed it was 10.25 Hz ± 1.9 Hz. Morphological evaluation of the ciliary motion after surgery demonstrated a normal, coordinated beat. CONCLUSIONS: The G/M-SVS does not appear to interfere with the physiological mechanism of mucocillary clearance since CBF remain within a normal range. SIGNIFICANCE: This is the first study that demonstrates an optimal tolerability and safety of the septo-valvular splints on nasal mucosa.
