Analgesic effect of ultrasound-guided extraoral mandibular nerve block compared to intraoral conductive block of the inferior alveolar nerve after lower third molar alveolectomy: a clinical prospective study.
Trial report in BMC oral health, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06009302 (Analgesic Effects of Extraoral Ultrasound Block of Mandibular Nerve for the Extraction of Lower Third Molars), which is not on this map. Cited by 1 paper.
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.

Abstract
backgroundThe analgesia after lower third molar alveolectomy is based on the use of non-steroidal anti-inflammatory drugs (NSAIDs) that have significant risks, and are contraindicated in the third trimester of pregnancy. Aiming to reduce NSAIDs use after this surgery, we quantified analgesic effects of ultrasound (US)-guided extraoral mandibular nerve block.
methodsThirty-six patients were equally allocated to the experimental or control group, based on their willingness to receive experimental US-guided extraoral mandibular nerve block for postoperative analgesia. The experimental block applied prior to lower third molar alveolectomy, was followed by standard intraoral inferior alveolar nerve block. In the control group, patients received only intraoral block of inferior alveolar nerve. All patients reported pain level (visual analogue scale, VAS) right after the application of blocks. The next day, patients reported duration of pain-free time and the use of analgesic.
resultsThe US-guided extraoral mandibular nerve block prolonged the pain-free time to 8 h (vs. 4 in control group, P < 0.001) and reduced NSAIDs use (12 patients needed analgesic in experimental vs. 17 patients in control group, P = 0.038). The application of experimental block was less painful (VAS = 2) than the application of intraoral inferior alveolar nerve block (VAS = 4, P = 0.011). In 8/18 patients in the experimental group US-guided extraoral mandibular nerve block solely achieved adequate surgical anesthesia.
conclusionUS-guided extraoral mandibular nerve block prolonged pain-free period and reduced the use of NSAIDs after lower third molar alveolectomy, thus proving to be successful analgesia method for this dental surgery. CLINICAL
