Abstract
In the evaluation of the beauty and functional integrity of the lower face, the oral cavity, teeth, mandible, maxilla, and the size and position of the tongue are important. The tongue locates forward and is larger than normal in prognathism, in which the jaw protrudes from the skull. It is not clear whether an enlarged tongue causes the open bite, protrusion or dental arch misalignment, or is a result of them. Here, we report two patients with mandibular prognathism and relative macroglossia, which were treated by mandibular setback surgery using a bilateral sagittal split osteotomy (BSSO) and excision of the tongue. This procedure achieved aesthetic improvement of the face and dentition.
Highlights
Mandibular setback surgery using a bilateral sagittal split osteotomy (BSSO) has routinely been used as an orthognathic surgical procedure for mandibular prognathism [1]
Relative macroglossia, is defined as the tongue being normal in size, but appearing large due to its anatomical reciprocation [2]
Class III malocclusion and an open bite [3]. It is not clear whether the macroglossia arises from mandibular prognathism or dental arch misalignment
Summary
Mandibular setback surgery using a bilateral sagittal split osteotomy (BSSO) has routinely been used as an orthognathic surgical procedure for mandibular prognathism [1]. Relative macroglossia, is defined as the tongue being normal in size, but appearing large due to its anatomical reciprocation [2]. The tongue locates forward and is larger than normal in prognathism, and this macroglossia may cause problems such as. (2014) Combined Therapy for Mandibular Prognathism: Sagittal Split Osteotomy with Excision of Tongue. Class III malocclusion and an open bite [3]. It is not clear whether the macroglossia arises from mandibular prognathism or dental arch misalignment. It must be kept in mind that the tongue will be relatively larger after a mandibular setback operation
