Inside-Outside Mastoidectomy for Middle Ear Paragangliomas: Surgical Technique and Outcomes.
Article in Cureus, 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
backgroundMiddle ear paragangliomas (glomus tympanicum) are rare vascular tumors that pose significant surgical challenges due to their location and vascularity. The inside-outside mastoidectomy combines transcanal and retroauricular approaches to optimize resection and preserve hearing. Methods: We conducted a retrospective observational study of eight female patients with stage A1-B3 glomus tympanicum treated at Carlos Andrade Marín Specialty Hospital between 2018 and 2024. Clinical presentation, imaging, intraoperative findings, complications, and audiological outcomes were analyzed. Results: All patients presented with conductive hearing loss and pulsatile tinnitus. Complete tumor resection was achieved in 100% of cases with mean intraoperative bleeding of 200 ± 82 milliliters and mean follow-up of 38 ± 18 months. Complications included three tympanic membrane perforations (37.5%) and one transient facial palsy (12.5%). Hearing improvement was documented in 37.5% of patients. No tumor recurrences were observed during follow-up. Conclusion: Inside-outside mastoidectomy is a safe and effective approach for the management of middle ear paragangliomas, offering excellent tumor control and favorable hearing outcomes. Further studies with larger cohorts are warranted to validate these findings.
