AGMI presented high proportions of the fatty acid groups, characterized the total lipids in the orbital cavity. According to Ewin (1997), from the nutritional point of view, the ingestion of saturated fatty acids increases the content of serum cholesterol in humans; however, the total cholesterol content in plasma decreases when the ingestion of saturated fatty acids is replaced with monounsaturated fatty acids.
The remains of nests and tunnels were found on skullcap (externally), orbital cavity, nasal passages, skull base (Figure 3), jaw, pterygopalatine fossae, palate, open dental alveoli, temporal region (externally), sacrum, iliac (acetabulum, ileum, obturator foramen and auricular surface).
The shape of the orbital cavity is less round in older women (p = 0.045), and this tendency towards virilization of older female skulls can also be observed in the margo supraorbitalis (p = 0.056) and in the reduced size of the tubera parietalia (p = 0.069).
INTRODUCTION: Anatomically, the orbital cavity has an intimate topographical relationship to the surrounding paranasal sinuses.
Specimen.--The ocular adnexa are those anatomic structures that surround the eyeball, protect it from injury, and facilitate its functioning; this includes the conjunctiva (palpebral and bulbar), orbital cavity soft tissues, main lacrimal gland, accessory lacrimal glands, nasolacrimal drainage system (including the upper and lower canaliculi, lacrimal sac, and nasolacrimal duct), and the eyelid.
They can also cause retro-orbital pain, proptosis, and ipsilateral optic atrophy as a result of erosion into the orbital cavity. (1) Other initial symptoms include pain and headache, which can occur in almost any region and are nonspecific.
