“…Besides these, Bone scintigraphy with Tc pyrophosphate 99, is an auxiliary diagnostic method that has proven effective in monitoring bone growth by identifying areas of increased osteoblastic activity [2,[6][7]. In the present case, Planar and SPECT images showed asymmetrical, unilateral increased tracer uptake in the right mandibular condyle suggesting active condylar hyperplasia.…”

“…Progressive facial asymmetry due to unilateral CH must be differentiated from other states of overdevelopment like hemifacial hypertrophy (unilateral enlargement of all hard and soft tissues of face), unilateral macrognathia (unilateral mandibular hypertrophy, which is a three dimensional enlargement of mandible, including condyles, ramus and ends at midline of symphysis) and laterognathia (asymmetrical prognathism where both condyles are equal in size) [7]. Chondroma and osteochondroma may produce similar symptoms and signs, but they are often localized, grow more rapidly and may cause even greater asymmetric condylar enlargement [1,2,4].…”

A 30-year-old male patient came to the dental OPD with a chief complaint of slowly progressing facial asymmetry following a facial trauma three years back. On inspection facial asymmetry was evident due to elongation of right lower half of the face with the mandible deviated towards the left side. The prominence of chin appeared shifted towards the left side. On palpation all inspectory findings were confirmed, condylar movements appeared limited on the right side. A non tender bony prominence was appreciated in the pre auricular region during mandibular movements. On examination, the right condylar enlargement resulted in facial asymmetry, elongation of right lower half of the face shifting the chin prominence to the left side, and limited movements on the right side. Based on the history and clinical findings the provisional diagnosis of unilateral CH of right side was made. Patient's consent for clinical pictures could not be obtained.Radiographic evaluation by panoramic and conventional tomographic views revealed an enlarged bulky, right condylar head with a thick condylar neck. The ramus appeared elongated and the lower border of the right side of mandible was thickened. Computed tomography (CT) and 3 Dimensional (3D) CT scan findings supported the clinical diagnosis [Table/ Fig-1 Fig-2]. After performing all routine blood investigations which were within the normal range, right condylectomy was performed and histopathology of the specimen confirmed the diagnosis of condylar hyperplasia. A second surgery of osteotomy of the mandible was planned for esthetic reasons.

“…Scintigraphy using technetium-99 methylene bisphosphonate was advocated as a method for distinguishing the growing condyle from nongrowing one. 7 Phosphates are metabolized by bone cells in 3 hours and are incorporated in the areas of new bone formation. 10 After 3 years and 4 months of isotope examination with 6-month intervals, growth of the condyle decelerated and the patient was ready for the surgery (Fig.…”

“…CH manifests itself in patients with ages ranging from 11-30 years, showing no predilection for the left or right side. [6][7][8] Differential diagnosis includes hemifacial hypertrophy (enlargement of all soft and hard tissues on one side), unilateral macrognathia (includes condyle, ramus, and ends at the midline), laterognathia, chondroma, and osteochondroma. Conditions that initiate after the age of 20 are most often related to some type of proliferative pathology.…”

Objective: This case report presents the diagnosis and short-and long-term treatment results of an orthodontically and surgically treated patient with condylar hyperplasia. Materials and Methods: Condylar hyperplasia was diagnosed in an 18-year-old patient. In the clinical and radiologic examination, asymmetrical face, overdevelopment of the head and lengthening of the neck of the right condyle, deviation of the menton to the opposite side, temporomandibular joint pain, occlusal canting, slight open bite in the affected side, and an impacted upper right premolar were detected. Technetium-99 radioisotope scanning was made in 6-month intervals, and surgery was planned and performed. Changes were measured on the cephalograms taken at the beginning of orthodontic treatment, before and after surgery, at the end of fixed treatment, and in 4 years 6 months follow-up period. Results: Skeletal and dental Class I relationship was established and the profile improved. Slight increase of the vertical dimension was observed in the finishing and follow-up cephalograms. Conclusion: In order to decide the appropriate time for surgery for condylar hyperplasia patients in which osteoblastic activity continues, isotope-scanning examination is a must. Short-term results achieved with the orthodontic and surgical treatment were satisfactory and were maintained in the long term. (Turkish J Orthod 2013;26:103-113)

RESUMEN:Las deformidades dentofaciales (DDF) son conocidas y su diagnostico es cada vez mas frecuente; las DDF asimétricas son un grupo de enfermedades de complejo manejo debido a las condicionantes estéticas y funcionales comprometidas. La etiología es variada, aunque la hiperplasia condilar suele estar asociada en los pacientes adolescentes y adultos; su diagnostico se establece mediante análisis facial, estudio con medicina nuclear, tomografías computadorizadas y otros exámenes. La terapéutica mas aceptada hoy día consiste en la condilectomia parcial y la corrección de la deformidad facial basada en las necesidades estéticas y funcionales del paciente. El objetivo de esta revisión es determinar las condicionantes actuales asociadas al diagnostico y tratamiento de las DDF asimétricas y el papel que cumple la hiperplasia condilar en el desarrollo de estas alteraciones faciales.PALABRAS CLAVE: asimetría facial, hiperplasia condilar, deformidad facial. INTRODUCCIONLas deformidades dentofaciales (DDF) se caracterizan por presentarse en cerca del 5% de la población (Bailey et al., 1997) y consiste en un grupo de síntomas que determinan una deficiencia funcional y estética que limita las actividades diarias como la fonación y la masticación, llegando a generar también alteraciones en la postura cráneo cervical, dolor en la articulación temporomandibular junto a las alteraciones en las características psicológicas y las relaciones sociales del portador de la patología (Wolford & Fields, 2000).Dentro de las DDF mas reconocidas están las patologías sagitales caracterizadas por la deficiencia o exceso anteroposterior de maxila y/o mandíbula, patologías verticales con sus síndromes faciales corto y largo y también las patologías transversales donde destacan las compresiones maxilares o mandibulares y las asimetrías faciales (Wolford & Fields). La asimetría facial subclínica es común, incluso en sujetos saludable y aparentemente sin alteraciones faciales; Ferrario et al. (1994) estudiaron 40 mujeres y 40 hombres sin alteraciones faciales y determinaron asimetría facial en tejidos blandos entre el lado izquierdo y el derecho. En este tipo de pacientes, asintomáticos, Sanders et al. (2010) también observaron asimetrías en los tamaños de la rama mandibular sin identificar asimetrías en el tamaño condilar, lo cual seria explicado por la adaptación y remodelación condilar que podría mantener homogéneos los cóndilos estudiados.La DDF asimétrica es anormal, de forma que es necesario definir su etiología, que según Pirttiniemi (1994) son consecuencia de alteraciones prenatales embriológicas (como la microsomia hemifacial), prenatales fetales (como la torticolis muscular congénita) y postnatales (como el crecimiento unilateral excesivo, infecciones, trauma).
