A Case of Broken Local Anesthetic Needle in the Pterygomandibular Space; Diagnostic Approaches and Surgical Management.
Article in Diagnostics (Basel, Switzerland), 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Needle fracture during dental local anesthetic injections is a rare but significant, potentially serious complication. Various approaches for the location and removal of broken needles have been described; however, there are several difficulties and concerns related to the potential complications and critical anatomic challenges peculiar to the head and neck region. In this case, we describe the diagnostic approaches utilized in locating a broken needle that migrated in the pterygomandibular space following gag reflex, and sudden head movement of a middle-aged male patient. A meticulous diagnostic approach was employed to locate the needle utilizing CBCT scan, CT scan with contrast, and C-arm X-ray machine. The needle was successfully retrieved using an angled hemostat inserted through an oral incision, guided by a C-arm X-ray machine and ENT endoscopic instruments. While careful planning could prevent many complications that may arise during oral surgical procedures, inadvertent events leading to serious complications should be addressed using the appropriate and timely diagnostic techniques pre-and intra-operatively.
