• Hospital Ruber Internacional (Grupo Quirónsalud) – Madrid, Spain

Dr. César M. Colmenero Ruiz is the Head of Maxillofacial Surgery at Hospital Ruber Internacional (Grupo Quirónsalud) and an internationally recognized surgeon in craniomaxillofacial surgery, facial plastic surgery, and otolaryngology–head & neck surgery. Trained through Spain’s elite MIR system—ranked Nº1 nationwide twice (1987 and 2000)—he brings 35+ years of experience managing highly complex deformities and oncologic cases of the face, skull base, orbit, jaws, and upper aerodigestive tract.

His unique dual specialization (Maxillofacial and ORL–Head & Neck) positions him as a reference for multidisciplinary tumor resections and reconstructions, difficult post-traumatic and post-oncologic sequelae, advanced orthognathic surgery (including complex occlusal/aesthetic corrections), cleft lip and palate care, orbital deformities, craniofacial syndromes, and OSA (SAOS) treatment through jaw surgery. He is known for meticulous planning with orthodontists (daily case reviews), long-term follow-up, and consistently refined occlusal and facial aesthetic outcomes.
