“…Although the intraoral technique is commonly used, it may be associated with serious complications such as intravascular injection, diplopia, transient ophthalmoplegia, and infraorbital nerve injury. 19,20 Moreover, these techniques may be difficult to perform under imaging guidance. The coronoid approach may be easier to perform under imaging guidance because the injection point is outside the oral cavity and the maxillary nerve is blocked via the PPF.…”

Background: Bleeding is the frequent intraoperative complication in most of the surgeries and remains a challenge for the surgeons and anesthesiologists. Major blood loss during FESS is rare but even a small amount of bleeding disturbs the endoscopic surgery field, increases the likelihood of complications, lengthens the time of surgery and results in incomplete surgery. The greater palatine canal (GPC) local injection is used to limit posterior bleeding during sinus surgery. Objective:To study the effect of pterygopalatine fossa block on intraoperative bleeding and operative field optimization during endoscopic sinus surgery.Methods: Prospective double blind randomized control trial. Thirty six patients were recruited in the study who also acted as their own control. PPFB was done only on one side of the nostril and the side was randomized by the lottery; neither the patient nor the operating surgeons were aware of the laterality. Boezaart score was used to quantify the intra-operative blood loss.Results: Blood loss between block group and non-block group was compared. Patients in block group had more stable hemodynamics with no fluctuations, better visibility of the surgical field and decreased blood loss as compared with non-block group. Conclusion:Greater palatine fossa block is a useful adjunct in patients undergoing endoscopic sinus surgery. It provided more stable hemodynamics, good operative conditions by lowering blood loss.

“…The greater palatine approach was successful and useful, providing profound anesthesia in the hemi-maxilla, if practiced properly. 6 Administration of LA plays a major role in the success of various dental procedures as pain control is one of the keys for patient satisfaction, cooperation, and to avoid its associated complications. The precise and accurate location of ICF and GPF is important for several specialties of JOHCD dentistry and otolaryngology, as the failure leads to inadequate anesthesia.…”

Introduction:The greater palatine foramen (GPF) and incisive canal foramen (ICF) play an important role in administering the local anesthetics.Aim: To evaluate the anatomic and morphologic variability of GPF and ICF in relation to age and gender of Saudi dental patients using cone beam computed tomography (CBCT) scans. Materials and methods:This descriptive cross-sectional study evaluated the 182 CBCT scans of Saudi dental patients who were examined for GPF (n = 364) and ICF (n = 182) who had attended a private dental school. The relationship of GPF and ICF to the surrounding structures, midline maxillary suture (MMS) to the posterior border of the maxilla, dimensions and opening direction of ICF, and the dimensions of the canals were evaluated. Chi-square test, independent Student's t-test, and analysis of variance (ANOVA) tests were applied to elicit statistical significance.Results: Findings revealed that the gender variations were significant in lateral to medial diameter GPF, GPF distance to midline, GPF distance to posterior maxilla, and distance between ICF to GPF. Similarly, age groups showed differences in GPF distance to midline, and distance between ICF and GPF. A significant positive correlation between age and distance of IC to GPF was observed (r = 0.14, p = 0.007). Age showed a significant positive correlation with IC length (r = 0.151, p = 0.041). Conclusion:Age and gender differences were obvious with regard to dimension and morphology of the GPF, ICF, and other adjacent structures among Saudi dental patients as revealed by CBCT scans.
