1 · What the graph read from it

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.

2 · The registry

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 and importanceCombined petrosectomy is a well-established technique in adult skull base surgery, offering wide exposure and enabling complete resection of complex lesions. In pediatric patients, its use remains uncommon because of the lower incidence of skull base tumors and age-dependent anatomic limitations, particularly in the developing temporal bone. We present a case of combined petrosectomy in a 7-year-old child and review the developmental anatomy relevant to its feasibility in children. CLINICAL PRESENTATION: A 7-year-old girl presented with progressive gait imbalance, dysarthria, and cranial nerve deficits. MRI revealed a large petroclival dermoid cyst causing brainstem compression. A mini-combined petrosectomy was performed, achieving gross total resection including the capsule with no complications. Postoperative recovery was uneventful.

conclusionThis case demonstrates that combined petrosectomy can be performed safely and effectively in selected pediatric patients once age-related anatomic conditions approach those seen in adults, as confirmed by preoperative imaging. These anatomic changes directly influence the feasibility and safety of combined petrosectomy in children.
