Rhinitis medicamentosa: therapeutic effect of diode laser inferior turbinate reduction on nasal obstruction and decongestant abuse.

BACKGROUND

The purpose of this study was to evaluate long-term outcomes of an outpatient-based diode laser inferior turbinate reduction (ITR) in therapy-refractory rhinitis medicamentosa (RM).

METHODS

In a prospective clinical investigation, 42 consecutive RM patients underwent videoendoscopic ITR with a diode laser after topical anesthetic preparation. Intra- and perioperative details were recorded including the occurrence of bleeding, crusting, pain, or discomfort. Treatment efficiency was assessed by follow-ups 1 and 6 weeks as well as 6 and 12 months after surgery. Subjective pre- and posttherapeutic nasal airflow (NA) and patient satisfaction were rated on visual analog scales (VASs). Assessment of the long-term objective clinical effectiveness was based on rhinomanometry, IT photodocumentation, and the recurrent need for decongestants.

RESULTS

Preoperative addiction to decongestants lasted 5 +/- 2 years (mean +/- SD). There was no major bleeding requiring nasal packing, and there were no other perioperative complications. Postoperative edema disappeared within the 1st week and crusting within 6 weeks after surgery. VAS was characterized by very low values for intraoperative pain and discomfort and high postoperative patient satisfaction. After 6 months, NA data revealed a significant improvement of subjective VAS and objective rhinomanometry (250.4-413.9 cm3/s inspiration at 150 Pa). A total of 88% of patients managed to successfully stop decongestant abuse after 6 months (74% after 1 year).

CONCLUSION

In therapy-refractory RM, outpatient diode laser ITR of hyperplastic IT represents a highly effective, safe, and well-tolerated treatment option that provides long-lasting recovery by markedly improving NA and stopping addiction to nasal decongestants.
