Nasal Air-Jet Sensitivity Differentiates Empty Nose Syndrome and Turbinate Reduction Patients: A Pilot Study.
Article in The Laryngoscope, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesAbnormal nasal mucosal function has been frequently implicated in the symptomatology of empty nose syndrome (ENS), yet with limited evidence. This prospective pilot study aims to compare nasal mucosal sensitivity to air-jet stimuli between ENS patients and patients who underwent septoplasty/turbinate reduction (septo-turb) surgery, but without ENS symptoms.
methodsSeven ENS and seven septo-turb subjects were recruited through a sample of convenience (from 06/2023 to 09/2024) due to the rarity of ENS. A precise, 0.25 s air jet ranging from 0.5 to 5 L/min was delivered via a 25-gage microcannula, with a 0.4 × 1.6 mm side opening placed 2 mm from the mucosal surface at predetermined sites that include the medial and lateral side of the nasal valve, the head and the center of inferior turbinate and their opposing septum. Detection thresholds were determined using a single-staircase method in 0.5 L/min steps.
resultsThe ENS group had a significantly higher (less sensitive) threshold than the septo-turb group for the septum opposing the center of the inferior turbinate (ENS: 2.43 ± 1.37 L/min; septoplasty: 1.39 ± 1.27 L/min, p = 0.016); however, not for other sites. This regional threshold significantly correlated with all self-reported symptom scores (NOSE, SNOT-22, ENS6Q, VAS) (r = 0.45-0.54, all p < 0.05).
conclusionSignificant regional differences in air-jet stimulus sensitivity between ENS and septoplasty patients were found that significantly correlated with symptom scores. A future larger sample size would make a more definitive conclusion. LEVEL OF EVIDENCE: 3:
