Rigorous Medical Education and Training

Corey S. Maas’s academic foundation was laid at the University of California, Berkeley, where he earned a Bachelor of Science in Biological Sciences with honors. During his undergraduate years, he distinguished himself through research on tissue engineering and participated in community outreach programs that introduced underserved youth to science and medicine. This early exposure to both laboratory investigation and public health advocacy shaped his commitment to evidence‑based practice and reinforced his resolve to pursue a career that merges scientific discovery with tangible patient impact.

Following his undergraduate success, Dr. Maas attended Stanford University School of Medicine, where he graduated cum laude with a Doctor of Medicine degree. At Stanford, he excelled in the rigorous curriculum, receiving the Dean’s Award for Clinical Excellence and contributing to pioneering studies on wound healing and scar modulation. His clinical rotations were marked by a relentless curiosity, leading him to seek mentorship from leaders in reconstructive surgery, craniofacial anomalies, and aesthetic medicine. These formative experiences honed his diagnostic acumen and deepened his appreciation for the delicate balance between form and function.

Upon completing medical school, Dr. Maas pursued a residency in Plastic Surgery at the University of California, Los Angeles (UCLA), a program renowned for its high case volume and emphasis on both aesthetic and reconstructive procedures. During his residency, he mastered microsurgical techniques, performed hundreds of complex flap reconstructions, and refined his skill set in facial trauma management. Recognizing the need for advanced specialization, he subsequently completed a fellowship in Facial Plastic and Reconstructive Surgery at the University of Southern California (USC), where he focused on rhinoplasty, facial aesthetic surgery, and craniofacial reconstruction. This comprehensive training equipped Dr. Maas with an unparalleled depth of knowledge, allowing him to address a broad spectrum of facial challenges with precision and confidence.

Surgical Expertise

Corey S. Maas’s surgical repertoire is anchored in a mastery of facial plastic surgery, a discipline that demands both artistic vision and meticulous technical execution. His expertise encompasses a wide array of procedures, ranging from subtle rejuvenation techniques to complex reconstructive interventions. In the realm of facial aesthetic surgery, Dr. Maas is celebrated for his ability to harmonize facial proportions, employing refined methods such as volume restoration, fat grafting, and dermal filler placement to achieve timeless results. His patients frequently commend his nuanced understanding of facial dynamics, which translates into outcomes that look effortless yet are grounded in sophisticated anatomical insight.

Reconstructive facial surgery stands as a cornerstone of Dr. Maas’s practice, particularly for patients who have endured trauma, oncologic resections, or congenital deformities. Leveraging his fellowship training, he performs intricate reconstructions that restore both appearance and function, utilizing advanced flap techniques, bone grafting, and three‑dimensional planning technologies. Notably, his work in craniofacial surgery has restored normal facial symmetry for individuals with complex skeletal anomalies, integrating interdisciplinary input from neurosurgeons and orthodontists to deliver comprehensive, life‑changing solutions. Each reconstructive case is approached with a commitment to minimizing donor‑site morbidity and optimizing long‑term stability, reflecting his dedication to patient safety and functional preservation.

Rhinoplasty, often regarded as one of the most technically demanding aesthetic procedures, is a particular passion of Dr. Maas. He combines traditional open and closed techniques with cutting‑edge technologies such as computer‑assisted simulation and ultrasonic osteotomy to sculpt noses that are proportionate to each patient’s unique facial architecture. His approach emphasizes preservation of nasal function, careful cartilage handling, and precise dorsal aesthetic lines, resulting in outcomes that are both aesthetically pleasing and physiologically sound. Whether addressing subtle tip refinement or extensive dorsal reconstruction, Dr. Maas’s rhinoplasty results are distinguished by their natural appearance, durability, and the harmonious integration of form and function.
