Management of patulous Eustachian tube dysfunction following bariatric surgery: a case report.
Article in Frontiers in surgery, 2025. 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
Patulous Eustachian Tube (PET) dysfunction is a rare condition characterized by an abnormally open Eustachian tube, leading to symptoms such as autophony, auditory fullness, and pulsatile tinnitus. This case report describes a 48-year-old female weighing 72.4 kilograms who developed persistent autophony and hearing her own breathing and heartbeat sounds following significant weight loss after sleeve gastrectomy. Initial treatments, including bilateral ventilation tubes, provided minimal relief. Diagnosis of PET was established through clinical and nasopharyngeal examination in the ear, nose and throat (ENT) department, revealing bilaterally open Eustachian tubes with a pronounced defect on the left ear. Surgical management included removal of the ventilation tubes, bilateral balloon dilation of the Eustachian tubes, and fat injection with plasma into the tubal opening (medial), utilizing fat harvested via liposuction. The patient was observed to have stable condition when her weight is above 80 kilograms, but the symptoms recurred while being under 80 kilograms, therefore her PET dysfunction was weight dependent. Postoperative outcomes showed temporary symptomatic relief lasting six months, with partial symptom recurrence. This case highlights the role of combined surgical interventions in managing PET and underscores the need for further research to develop durable treatment solutions for this challenging condition.
