Insights

Posterior nasal nerve (PNN) cryoablation using ClariFix for chronic rhinitis can cause epistaxis and nasal swelling. Further research is needed to understand PNN cryoablation

Area of Science:

  • Otolaryngology
  • Medical Device Safety
  • Surgical Innovation

Background:

  • Chronic rhinitis affects millions, impacting quality of life.
  • Posterior nasal nerve (PNN) cryoablation is an emerging treatment.
  • ClariFix is an office-based device for PNN cryosurgical ablation.

Purpose of the Study:

  • To analyze adverse events associated with ClariFix device use.
  • To identify safety concerns from FDA Manufacturer and User Device Facility Experience (MAUDE) database reports.

Main Methods:

  • Retrospective review of Medical Device Reports (MDRs) in the FDA MAUDE database.
  • Analysis of 12 adverse events linked to ClariFix from January 2017 to August 2020.

Main Results:

  • Epistaxis (nosebleeds) was a common adverse event.
  • Nasal swelling was another frequently reported adverse event.
  • 12 adverse events were identified and analyzed.

Conclusions:

  • ClariFix PNN cryoablation is associated with epistaxis and nasal swelling.
  • Further investigation is required to determine PNN cryoablation's specific risks for epistaxis in different patient groups.
