Greater Palatine Canal

Introduction: The greater palatine foramen (GPF) is located in the posterior part of the hard palate between the articulations of hard palate with the maxilla. GPF continues posteriorly and upwards as greater palatine canal (GPC) which opens in to the inferior wall of pterygopalatine fossa. Exiting the foramen rotendum, maxillary nerve enters the pterygopalatine fossa where it can be blocked. The intraoral route of GPF approach can be preferred for maxillary nerve block because of its low incidence of complications and high success rate. For achieving a painless intra operative period in procedures involving the maxillary region and for tooth extraction achieving a perfect maxillary nerve block is of at most importance. Our present study is aimed at correctly locating the position of GPF, its shape and patency in south Indian population which will be helpful for the intra oral approach of maxillary nerve block through the GPF Materials and Methods: The study was conducted in 30 dry adult skull bones of both sex. The molar relation, shape and the patency of the GPF were observed, the readings were obtained, statistically analyzed and compared with other studies. Results: In our observation on both side of skull, it was noted that GPF was located opposite to the 3rd molar in 90% of cases. Oval shaped GPF is most commonly found in our study which accounts to 53.35% and the overall patency rate for GPF was 95% in our study. Conclusion: Analysis and comparison of data has proven that the position, shape and patency of GPF may vary according to different races. This study has also confirmed that the maxillary nerve block via GPF is relatively safe and easier due to the consistency of the position, shape and the patency of the GPF in south Indian population. KEY WORDS: Greater palatine foramen, maxillary nerve block, regional blocks, Greater palatine canal, pterygopalatine fossa, Maxillary nerve.

The Ideal

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.
