The pterygopalatine ganglion is important in the regulation of the intraocular pressure and in the cerebral vasodilatation connected with headache of vascular origin. Four human ganglia were dissected, fixed in formalin and serially sectioned with a 6 microns thickness. The volume of the ganglion was calculated by point-counting and stereological parameters were determined using the test-system M42 with light microscopy. The PG volume was (mean +/- standard error of the mean) 5.6 +/- 0.5 mm3. The volume density of neurons was 51.1% +/- 3.4%, and the unitary volume of the neurons was 41,200.0 +/- 2,250.0 microns. The numerical density was 12,600.0 +/- 677.0 neurons by mm3, therefore approximately 70,560 neurons by ganglion.
