Extraction of the impacted mandibular third molar (IMTM) is common in oral surgery, but its postoperative pain is severe. Ultrasound-guided inferior alveolar nerve block (UGIANB) is an analgesic technique in the mandibular nerve region. We describe UGIANB using a mouth opener and report the cases with a good postoperative course.

- - The ultrasound-guided selective glossopharyngeal nerve block (UGSGNB) offers a better technique for performing glossopharyngeal nerve blocks, especially useful for patients who experience a gag reflex during dental treatment.
- - Two case studies demonstrate the successful application of UGSGNB: a 67-year-old man with health complications and a 25-year-old woman with dental phobia.
- - Both patients underwent their dental procedures without gagging or complications, suggesting that UGSGNB may reduce the need for general anesthesia and deep sedation for patients with a severe gag reflex.
Purpose: Ultrasound-guided inferior alveolar nerve block (UGIANB) is a mandibular analgesic procedure in which local anesthetic is injected into the pterygomandibular space (PMS). Several studies have reported the clinical efficacy of UGIANB for mandibular surgeries; however, its effective range has never been investigated. We performed a cadaveric study to investigate the success rate of UGIANB injections and to determine whether injected dye could stain the mandibular nerve (MN) trunk and its branches.
