Objective:
To compare the clinical outcomes of radiofrequency ablation of the intraturbinate segment of the posterior nasal nerve (RAPN) alone versus combined RAPN with CO₂ laser posterior nasal nerve neurolysis (RPN3) in patients with chronic rhinitis refractory to medical therapy.
Study Design:
Retrospective cohort study.
Setting:
Single tertiary care center.
Methods:
Adult patients with chronic rhinitis unresponsive to medical treatment for over 6 months who underwent either RAPN or RPN3 between February 2023 and May 2024 were included. Inclusion criteria were 24-hour reflective total nasal symptom score (rTNSS) ≥ 3, rhinorrhea score ≥1, and NOSE score ≥11. Exclusion criteria included chronic rhinosinusitis, nasal polyps, and coagulopathy. Demographics and comorbidities were documented. Primary endpoints were changes in rTNSS, NOSE scores, and response rate (≥30% improvement from baseline) at 1-, 3-, and 6-months posttreatment.
Results:
A total of 101 patients were analyzed (RPN3: 76; RAPN: 25). Baseline rTNSS and NOSE scores were comparable between the two groups (P = .144 and .414, respectively). Both groups demonstrated significant improvements in rTNSS and NOSE scores at all follow-up points (P < .001). From 1 to 6 months, RPN3 achieved significantly greater improvements compared to RAPN (P = .039-.045), particularly in the rhinorrhea and nasal itching sub-scores (P = .003-.039). Response rates for rTNSS ranged from 91% to 100% in the RPN3 group and 84% to 96% in the RAPN group.
Conclusion:
Both RAPN and RPN3 are effective in treating chronic rhinitis unresponsive to medication. The addition of CO₂ laser posterior nasal nerve neurolysis (RPN3) provides superior symptomatic relief, particularly for rhinorrhea and nasal itching.

Nasal Cannula
A nasal cannula is a lightweight tube split at one end into two prongs and placed in the nostrils. It is typically used to deliver low to medium levels of oxygen.
Suggested flow rate: The suggested flow rate for a nasal cannula typically ranges between 1 and 6 L/min.

01:14Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
01:23Chronic Pharyngitis
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
