“…We congratulate Wirinaree Kampitak et al for their interesting cadaveric study1 to assess the accuracy and feasibility of a novel technique for ultrasound-guided maxillary nerve block using the lateral pterygoid plate approach via the pterygopalatine fossa by an anterior infrazygomatic approach in a soft cadaveric model. However, we have two important concerns with this study.…”

Background and objectivesBlockade of the trigeminal nerve and its branches is an effective diagnostic tool and potential treatment of facial pain. Ultrasound-guided injections in the pterygopalatine fossa (PPF) to block the trigeminal nerve divisions and sphenopalatine ganglion have been described but a consensus has yet to be reached over the ideal approach. We sought to delineate and compare the various approaches to the ultrasound-guided trigeminal divisions blockade via the PPF.MethodsThe literature search was performed by searching the National Library of Medicine’s PubMed database, the Cochrane Database of Systematic Reviews and Google Scholar within the date range of January 2009–March 2019 for keywords targeted toward “trigeminal nerve,” “maxillary nerve,” or “pterygopalatine fossa,” “ultrasound,” and “nerve block,” using an English language restriction. Six papers were included in the final review: one prospective double-blinded randomized controlled trial, one prospective descriptive study, one case series, two case reports, and one cadaveric study.ResultsThere are three main approaches to the ultrasound-guided trigeminal nerve branches blockade via the PPF: anterior infrazygomatic in-plane, posterior infrazygomatic in-plane, and suprazygomatic out-of-plane approaches. Each showed injectate spread to the PPF in cadaver, adult and pediatric patients, respectively.1–5 Injectate used varied from 3 to 5 mL to 0.15 mL/kg.ConclusionsThese studies demonstrated that the PPF is a readily accessible target for the ultrasound-guided maxillary nerve block via three main approaches.2 The ideal approach is yet to be determined and must be further explored.

“…We thank Dr Alfaro-de la Torre et al 1 for their interest and acknowledge their valuable contribution to our article 2. Certainly, in addition to the maxillary tuberosity (MT) and lateral pterygoid plate (LPP), the coronoid process is an interfering structure for ultrasound-guided maxillary nerve block using the LPP approach via the pterygopalatine fossa (PPF).…”

A Cadaveric Study of Ultrasound-Guided Maxillary Nerve Block Via the Pterygopalatine Fossa

Abstract: This cadaveric study suggests that ultrasound-guided maxillary nerve block using the LPP approach via the PPF has a high degree of accuracy and feasibility. Further studies are required to confirm its efficacy and safety for clinical application.
