SALADO R, Lupe; ALVAREZ S, Lupe  and  BRUNETTO M, Beatriz. Subperiostial orbital abscess and apex syndrome as a complication after a mandibular molar extraction. Rev. Otorrinolaringol. Cir. Cabeza Cuello [online]. 2009, vol.69, n.2, pp. 145-152. ISSN 0718-4816.  doi: 10.4067/S0718-48162009000200010.

Introduction: Infection dissemination from mandibular teeth to the orbit and adjacent structures is infrequent, but nevertheless serious, as they may cause severe problems, including vision loss. Aim: The purpose of this study is to present a rare and interesting case of such a dissemination, to discuss the possible routes of infection propagation, and to alert the different specialists involved on the possible complications after dental extractions, such as visual loss. Report of the case: The case of a 43-year-old previously healthy male is presented. The patient was sent to the Medical Legal Service for clinical forensic examination after total vision loss of the right eye, caused by optic atrophy as a complication of orbital apex syndrome, after the extraction of the third right mandibular molar. Conclusions: Opportune and aggressive treatment is crucial to stop infection spread from adjacent structures to the orbit. Effective communication among the professionals involved avoids medical - legal complications and precludes permanent sequels to the patient.
