“…13 To the best of our knowledge, 6 authors in total have reported buccal bone devices. [13][14][15][16][17][18] The advantages of 2 buccal distractors include the possibility of rotational movement, better oral hygiene, the lack of the need for assessment of palatal bone shape, and preoperative adjustment of the distractor on a dental cast model. Using 2 buccal distraction devices created the possibility to allow asymmetrical elongation in AMDO.…”

“…Most studies exploring AMDO have applied a tooth-borne distractor device 3–12 . However, bone-borne distraction devices do not often cause tooth movement or damage as tooth-borne distractors do 13–18 . This study aimed to evaluate the efficacy of distraction of bone-borne AMDO for the management of maxillary hypoplasia in CLP.…”

Anterior maxillary distraction osteogenesis (AMDO) surgery for cleft lip and palate involves distraction of a segment of the anterior maxilla and advancement using 2 intraoral buccal bone-borne distraction devices. The anterior part of the maxilla is advanced anteriorly with less relapse which increases maxillary length and does not affect speech. We aimed to evaluate the effects of AMDO, including lateral cephalometric changes. Seventeen patients who had undergone this procedure were included in this retrospective study. The distractors were activated by 0.5 mm twice a day after a 3-day latency period. Lateral cephalometric radiographs were evaluated preoperatively, after distraction and removal of distractors, which were compared using the paired Student's t test. Anterior maxillary advancement was obtained in all patients with a median of 8.0 mm. Complications included nasal bleeding and loosening of distractors; however, there was no tooth damage or abnormal movement. The mean sella-nasion-A point (SNA) angle increased significantly, from 74.91°to 79.66°, the A pointnasion-B point angle from -0.38°to 4.34°, and the perpendicular line from nasion to Frankfort Horizontal (NV)-A point from -5.11 to 0.08 mm. The mean anterior nasal spine-posterior nasal spine length increased significantly from 50.74 to 55.10 mm, and the NV-Nose Tip from 23.59 to 26.27 mm. The mean relapse rate of NV-A was 11.1%. AMDO with bone-borne distractor resulted in less relapse and effectively corrected the maxillary retrusion.

“…VSP has been shown to reduce operative length with more efficient and predictable movements, and may provide greater long-term results given the specificity of the custom plates. 34-36 At our institution, we have moved entirely to VSP with custom plates for all of our patients because of the complexity of care and its reliability for achieving a satisfactory postoperative outcome. Given that VSP increases operational efficiency and provides predictable orthognathic results, we decided that combining our patient’s orthognathic and TMJ procedures together would not be prohibitive from a time standpoint and would allow for total correction of both deformities with one trip to the operating room.…”

Management of Bilateral Temporomandibular Joint Ankylosis and Class 2 Malocclusion in a Patient With Nager Syndrome

Nager syndrome is a rare hereditary syndrome characterized by severe mandibulofacial and pre-axial upper limb anomalies. Patients with Nager syndrome often exhibit syndromic Pierre-Robin sequence secondary to their hypoplastic mandible and require mandibular distraction osteogenesis to prevent dependence on a tracheostomy or gastric tube. This procedure, however, has been associated with temporomandibular joint (TMJ) ankylosis. TMJ ankylosis is a highly debilitating condition that dramatically impairs patients’ function and can result in facial asymmetry in affected children during periods of rapid facial growth. Surgical intervention is warranted in patients who fail physiotherapy; however, there is no gold standard treatment for surgically correcting TMJ ankylosis in patients with Nager syndrome. Herein, we detail the surgical management of TMJ ankylosis and class 2 malocclusion in a patient with Nager syndrome.

“…La discrepancia intermaxilar en los casos presentados era superior a 10 mm, y estaban asociados a malformaciones faciales de origen genético, motivo por el que se decidió realizar una cirugía de DO. Esto coincide con Wang et al 7 que indica que la DO maxilar total proporciona un mayor avance maxilar y es preferible ante la cirugía ortognática en pacientes jóvenes con malformaciones faciales.…”

La corrección quirúrgica de grandes asimetrías faciales son un desafío para el equipo quirúrgico. En dichos casos, los resultados de la corrección utilizando técnicas quirúrgicas convencionales son limitados, lo que hace necesario la utilización de otras herramientas terapéuticas. La distracción ósea (DO) es una de ellas, pues permite el estiramiento controlado del callo óseo previamente creado mediante osteotomías. La DO permite realizar cambios en el posicionamiento óseo de gran envergadura, favoreciendo el crecimiento óseo como mecanismo de acción. El objetivo de este artículo es describir los resultados quirúrgicos de DO intraoral del tercio medio facial utilizado en dos pacientes con severas asimetrías faciales asociadas a malformaciones de origen genético. Se relata el diagnóstico, la planificación, las herramientas tecnológicas utilizadas, técnica quirúrgica y los resultados obtenidos.
