Massive Submental Hematoma A Rare Complication After Osseous Genioplasty Literature Review and Case Report

Abstract

Genioplasty is a procedure designed for correction of chin deformities, designed to achieve aesthetic objectives, without functional changes. There are few complications associated with genioplasty been reported in literature, including neurosensory disturbances, teeth apices injury, muscle dysfunctions (mentalis muscle ptosis) and relapses with a rare complication been reported including mucocele in the chin region. However this patient post-operative an eventful the time was in the hospital which was forty eight hours (48hours) then patient discharge home with antibiotic and pain medication. One week follow up patient presented with subcutaneous hematoma extended from sub mental to the xiphoid region.

Guided Genioplasty: Comparison between Conventional Technique and Customized Guided Surgery

“…Related to the use of customized cutting guides, we can affirm that they allow us to design more complex osteotomy paths and to "take better advantage" of the patient's mandibular bone, being able to design more posterior cutting paths that provide more volume and thus avoid the "hourglass" deformity typical of some cases with poor planning [21,24,25].…”

“…Complications of genioplasty due to damage to the mentonian nerve or tooth apices are described in the scientific literature with a variation of 3% to 12% [14,23,24]. Although we consider that these are not frequent complications and that, with wide experience, they can be avoided, the safety and precision provided by VSP and the use of this technology during surgical manipulation are unequaled.…”
