- Vigorous irrigation of nasal chambers should dislodge cells and debris, which can be examined cytologically.
- Collection of cytological sample [Cytology: nasal flush aspirate] for investigation of:
- Quick procedure.
- Occasionally helps to clear discharge and debris from nasal passages, and reduce stertor.
- Occasionally produces tissue sample, for histopathological examination, if nasal mass very friable.
- Requires general anesthesia.
- May not provide material suitable for examination.
- Flexible rubber catheter (largest diameter which will comfortably fit through nares).
- Five ml syringe.
- Sterile saline.
- Sterile receptacle for cytological fluid preservation.
- Glass slides.
- gauze swabs.
- Receptacle for collecting debris flushed into mouth through nasopharynx.
A plastic 5 ml syringe case cut in half longitudinally.
- Time to induce general anesthesia.
Reasons for treatment failure
- Poor technique of collecting material produced by flushing nasal chamber.
- Lesion of interest poorly exfoliative therefore few cells collected.
