The clinical value and learning curve analysis of the modified areolar approach for endoscopic thyroidectomy.
Article in Surgical endoscopy, 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
objectiveTo compare the clinical outcomes and learning curve characteristics of the traditional bilateral areolar approach (BAA) and the modified areolar approach (MAA) in endoscopic thyroidectomy and to assess the advantages and potential for clinical dissemination of the modified technique.
methodsWe retrospectively reviewed 79 female patients who underwent endoscopic radical thyroidectomy for thyroid cancer. Patients were assigned to the BAA group or the MAA group according to the incision placement. Perioperative parameters were compared between groups, such as operative time, intraoperative blood loss, number of lymph nodes harvested, incidence of postoperative complications, and patient satisfaction. A cumulative sum analysis (CUSUM) was performed to construct learning curves and evaluate the progression of surgical proficiency.
resultsCompared with the BAA group, the MAA group demonstrated a significantly shorter operative time (P < 0.001), reduced intraoperative blood loss (P = 0.029), and a lower rate of short-term postoperative complications (P = 0.05). The CUSUM learning curve inflection point occurred earlier in the MAA group (20th case vs. 26th case), indicating more rapid acquisition of the technique.
conclusionBy optimizing incision placement and instrument alignment, the modified areolar approach shortens operative time, minimizes intraoperative trauma, and decreases complication rates. Its shorter learning curve and greater procedural stability facilitate faster mastery of endoscopic thyroidectomy, supporting its wider clinical adoption.
