Fractured Genial Tubercles Displaced to Mid-Floor of Mouth: A Rare Case Report.

Fractured and displaced genial tubercles are a relatively rare happening in the field of oral and maxillofacial trauma. These tubercles are attached to the geniohyoid and genioglossus muscles, which are associated with lingual mobility and deglutition. Separation of these unilateral tubercles can lead to sublingual pain, dysphagia and difficulty in swallowing. Review of literature shows that only <15 cases of fractured genial tubercles have been reported in the English literature until now. Surgical interventions have been rarely reported in the literature as most of the cases have been managed conservatively. We report a case of fractured genial tubercle, following trauma, which was intervened surgically.

Surgical mangement of fracture of unilateral genial tubercles / O tratamento cirúrgico de fratura de tubérculos Geni unilaterais

Traumatic fracture of unilateral genial tubercles and displacement to the mid-floor is rarely reported. These tubercles are attached to the geniohyoid and genioglossus muscles. Separation of these unilateral tubercles can lead to sublingual pain, dysfagia and difficulty in swallowing. A 28-year-old patient was admitted for sublingual pain. A fracture of the genial tubercle segment was discovered beneath the tongue. Surgical correction of this separated bone to allow it to return to its original position was performed without divulsion of the attached muscles. No evidence of complications from separated genial tubercles has been found after 3 years of follow-up.
