title: Descriptive and topographic anatomy of the accessory infraorbital foramen. Clinical implications in maxillary surgery.
abstract: OBJECTIVE
  Study of frequency and position of accessory infraorbital foramen in a large craniological sample.
  
  
  METHODS
  A sample of 1 064 skulls from the craniological collection of the Department of Anatomy, Pharmacology and Forensic Medicine of the University of Turin (Italy) was investigated.
  
  
  RESULTS
  Accessory infraorbital foramen was found in 4.7% of the skulls (5.4% in male and 4.26% in female skulls) with a higher frequency on the left side, both in male and in female skulls.
  
  
  CONCLUSIONS
  These results increase our knowledge of the interindividual anatomic variability of the infraorbital region and can be of help for the maxillo-facial surgeon, especially in trunk block of the infraorbital nerve.
