Nasopharyngeal stenosis in cats: a retrospective study of 21 cases comparing endoscopic and surgical treatment (2018-2022).

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
objectivesFeline nasopharyngeal stenosis (NPS) is an uncommon disease in cats. The aim of this study was to compare the outcome with endoscopic and surgical treatments.
methodsIn this retrospective study, medical records were searched for cases of NPS and cases were divided into three groups: endoscopic treatment (balloon dilation); surgical treatment; or no treatment. Data are presented as median and range. Success rates and length of post-procedure corticosteroid treatment were compared between the two treated groups.
resultsA total of 21 cases were included: 10 males and 11 females (median age 6.7 years, range 0.5-14.4). Clinical signs at the time of initial presentation included permanent stertor (19/21), increased respiratory efforts (9/21), nasal discharge (9/21) and cough/reverse sneezing (6/21) with a duration in the range of 3-60 months. Diagnosis was based on endoscopy (21 cases) and CT (19 cases). In total, 12 cases were treated with endoscopic balloon dilation; 11 cases demonstrated a complete resolution of clinical signs (two cats had two dilations) and one case showed incomplete improvement after one balloon dilation but was successfully treated surgically. Eight cats were treated surgically (including one cat that was originally treated with balloon dilation), including seven cases with complete resolution of clinical signs and one case with a rostral NPS that failed to respond. Two cats were not treated and are still alive more than 3 years after diagnosis. The success rate was not different between the endoscopic (11/12) and surgically treated cases (7/8) ( CONCLUSIONS AND RELEVANCE: This preliminary study suggests that minimally invasive endoscopic treatment of NPS has a high success rate and should be attempted in all cases with perforate stenotic membranes. When not achievable, extended palatoplasty can be recommended as a good alternative.
