Effect of Endoscopic Posterior Nasal Neurectomy on Laryngectomy-associated Rhinorrhea: A Feasibility Study.
Article in In vivo (Athens, Greece). The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
BACKGROUND/
aimRefractory rhinorrhea is common after total laryngectomy (TL). Because botulinum toxin injection and ipratropium bromide nasal spray have shown success in it, suggesting a hyperactive parasympathetic tone may play a role. Therefore, we sought to evaluate whether endoscopic posterior nasal neurectomy (ePNN) to include more nasal secretomotor fibers is a treatment option for laryngectomy-associated rhinorrhea. PATIENTS AND
methodsLaryngectomized patients with persistent rhinorrhea who underwent ePNN at both the middle and inferior meatus were enrolled. We evaluated the changes in 2-week Total Nasal Symptoms Score (TNSS) and rhinorrhea subscore over 6 and 12 months post ePNN treatment, as well as self-rated rhinorrhea using the visual analogue scale (VAS) at pretreatment and 12 months post-treatment. Adverse events, post-procedure medication reliance, and patient satisfaction were recorded.
resultsFive males (mean age, 62.4 years) with elapsed time from TL of 97.56±89.91 months were identified. ePNN significantly improved the average rhinorrhea subscore of TNSS at six months (p=0.037, Wilcoxon sign-rank test) and twelve months (p=0.047) compared to baseline. There were marginally significant improvements between baseline and at 12 months for overall TNSS (6.60±2.30 to 2.00±1.22, p=0.056) and VAS for rhinorrhea (7.80±0.84 to 2.00±1.58, p=0.062). No adverse event was reported, and four patients had excellent outcomes.
conclusionEndoscopic posterior nasal neurectomy is a safe and efficient alternative treatment for laryngectomy-associated rhinorrhea, with lasting improvement over one year. However, a large-scale study with more comprehensive measurements is needed to verify its long-term efficacy.
