A Study of the Anatomical Variations in the Position of the Greater Palatine Foramen in Adult Human Skulls and its Clinical Significance International Journal of Morphology
Dave,Mitesh R; Yagain,Vaishali Kiran; Anadkat,Samir.
Pain is a common distressing symptom in dental practice. Depending upon the cases, different techniques are used to relieve pain. One of these is peripheral trigeminal nerve block. Peripheral trigeminal nerve block anaesthesia has proved to be an effective and convenient way to anaesthetise large regions of oral and maxillofacial complex. This block can be intraoral or extra oral. The intraoral route is through the greater palatine foramen in which the dental surgeons enter into the pterygopalatine fossa, where the maxillary nerve is situated. The morphological variations in the position of greater palatine foramen may be of clinical importance in the administration of local anaesthesia and in palatal surgery. In the present study, the distance of greater...

Invasive intracranial aspergillosis spread by the pterygopalatine fossa in an immunocompetent patient BJID
Xiao,Anqi; Jiang,Shu; Liu,Yi; Deng,Kaihong; You,Chao.
Aspergillosis of the central nervous system (CNS) is an uncommon infection, mainly found in immunocompromised patients but rarely seen among immunocompetent patients. Herein we describe a 57 year-old immunocompetent man who suffered intracranial aspergillosis spread by the pterygopalatine fossa (PPF) following a tooth extraction. Based on magnetic resonance imaging (MRI) characteristics, in this report we focus on the spreading routes of CNS aspergillosis via communicative structures of the PPF, the relationship between clinical manifestations and the locations of the lesion, and propose a therapeutic strategy to improve the prognosis.

Relationship Between Pterygopalatine Fossa Volume and Cephalic and Upper Facial Indexes International Journal of Morphology
Coronado Gallardo,César Andrés; Suazo Galdames,Iván Claudio; Cantín López,Mario Gonzalo; Zavando Matamala,Daniela Alejandra.
The maxilary nerve can be block in the pterygopalatine fossa, entering from oral cavity via greater palatine canal. The aim of this study was to analyse the volume of the pterygopalatine fossa and its relationship with upper facial height and cephalic indexes. In 71 human adults skulls, without sex distinction, was determined the volume of the pterygopalatine fossa and cephalic and upper facial height indexes. Through a t test (p < 0.05) were compared the average volume between cephalic and facial types. The average volume of the pterygopalatine fossa was 1.2 mi (DS 0.297), were not found differences according to the cephalic or facial type.

Relationship Between Volume of Pterygopalatine Fossa and Block Anesthesia of Maxillary Nerve: A Pilot Study International Journal of Morphology
Aravena Torres,Pedro; Cresp Sinning,Nicole; Büchner Sagredo,Katherine; Muñoz Rocha,Carlos; Cartes-Velásquez,Ricardo.
Block anesthesia of maxillary nerve 9BAMN) is achieved by depositing anesthesia through greater palatine canal into the pterygopalatine fossa. Authors differ in the amount of anesthesia to be administered and the rate of complications (diplopia and hematomas), Coronado et al., (2008), measured the size of the pterygopalatine fossa finding an average of 1.2 ml, suggesting that amount of anesthesia for BAMN. The aim of this study is to compare the effectiveness of low doses of 1.2 ml (LD)versus traditional dose of 1.8 m. (TD) of anesthesia for BAMN and its adverse effects. A quasi experimental exploratory clinical study was performed involving 82 patients where the anesthetic technique was suitable for tooth extraction procedure; patients were randomized in...
