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

backgroundCranio-orbito-zygomatic approach (COZA) requires adequate SCALP, fascia and muscle retraction to access the zygomatic arch, malar eminence (ME) and inferior orbital fissure (IOF), which endanger the facial nerve branches. Performing skull base reconstruction also demands a layer-by-layer understanding of the SCALP and fasciae. We aimed to examine the relationship between the SCALP layers, temporal fascia (TF) and facial nerve branches from a surgical viewpoint and highlight the optimal dissection plane during the COZA.

methodThe SCALP and temporal fascia layers were examined using COZA on 10 formalin-fixed cadavers (20 sides). Stepwise dissections analyzed the relationships between SCALP layers, temporoparietal fascia, TF and facial nerve branches. In addition, facial dissections were conducted to examine the relationships between the facial nerve branches and the associated fasciae.

resultsThe temporoparietal fascia was continuous with the galea superomedial to superior temporal line. Facial nerve branches coursed between the galea and the TF. The TF divided into superficial and deep layers; superficial layer continuous with the pericranium and extending anteriorly toward periorbita. Following the superficial layer of the TF inferiorly provided a natural interfascial surgical plane for exposure of the ME. Deep layer of the TF further divided into medial and lateral laminae with an interfascial fat pad between them. The lateral and medial laminae attached to the lateral and medial surfaces of the zygomatic arch, respectively, and merged at the superior margin. CONCLUSıONS: Recognizing the interfascial plane between the superficial and deep layers of the TF and the deep interfascial fat pad, may improve surgical orientation and facilitate tissue retraction during exposure of the lateral orbital wall and ME in the COZA.
