Pterional dermal sinus: case report and review of the literature.
Review in Child's nervous system : ChNS : official journal of the International Society for Pediatric Neurosurgery, 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
introductionDermal sinus (DS) is a congenital condition of embryonic origin that occurs when the surface ectoderm fails to fully separate from the neuroectoderm, despite the neural tube remaining intact. Its most common location is the spinal region, followed by the occipital region. Off-midline presentation is extremely rare. The aim of this study is to present an atypical case of a dermal sinus located in the pterional region, outside the midline. CASE DESCRIPTION: A 4-year-old male patient presented with a mass in the tail region of the left eyebrow. Contrast-enhanced computed tomography revealed a dermoid cyst associated with a dermal sinus in the pterional region. Physical examination showed a skin dimple in the affected area. Complete surgical excision of the lesion was performed. DISCUSSION: Between January 2014 and March 2025, 23 cases of cranial dermal sinuses were diagnosed at our institution. The case presented is the only one with an off-midline location. According to the literature, only 21 pediatric cases of cranial dermal sinuses in the frontotemporal region have been reported since the 1970s. Due to the low prevalence of this location, there is no standardized surgical protocol. However, surgical treatment is unanimously recommended, as it allows for definitive resolution and prevents potential infectious or neurological complications.
conclusionLateral localization of cranial dermal sinuses is extremely rare. Surgical treatment plays a fundamental therapeutic and preventive role in avoiding complications.
