Condylar Hypoplasia Type 2

Condylar Hypoplasia Type 2 is a condition characterized by the unilateral overgrowth of a part of the jaw. Usually caused by a benign tumor called an osteochondroma on one condyle of the mandible. It consists of a bony projection covered by a cartilage cap and can cause pain, swelling, and limited range of motion in the affected area. It can develop at any age although more often during adolescence. The growth process can continue indefinitely, with progressive worsening of the facial asymmetry. It can result in asymmetry of the jaw, facial deformities, and malocclusion.

Common Symptoms

Individuals with this condition may experience facial asymmetry, misalignment of the upper and lower teeth, restricted ability to fully open or close the mouth, discomfort in the temporomandibular joint, difficulties with speech, chewing, and possible psychological effects due to the discomfort.

Procedure Performed

Lefort 1 Segmental Osteotomy. Bilateral Saggital Split Osteotomy. Genioplasty.

About This Patient

In high school and college, she noticed her gum line receding and misalignment in her jaws. Referred to Dr. Movahed, he recommended jaw surgery to address her growing jaw and small top jaw. Without the surgery, her teeth would have fallen out due to receding gums. After the surgery, she experienced no pain, improved facial symmetry, better breathing, and increased stamina. Looking back, she realizes the significant impact the surgery had on her appearance and overall well-being.

At the end of high school she noticed her gum line was receding. Her top and bottom jaw were also very misaligned. Dr. Movahed recognized it as a benign tumor called an osteochondroma. Dr. Movahed was able to remove the benign bone tumor, widen her upper jaw, and open her airway so she could breath through her nose better. She expands more on her story in the video.

“ In this video, Dr. Movahed discusses Christina’s complex case, marked by jaw asymmetry, a gummy smile, and excessive tooth exposure due to vertical maxillary excess. He explains that Christina’s issues stemmed from an abnormal growth in her jaw joint, causing facial asymmetry and discomfort. Dr. Movahed details the surgical interventions, including a low condylectomy to reduce joint growth by 8mm, realigning the jaw’s Pitch, Yaw, and Roll aspects, and correcting the vertical dimension of her face. These procedures successfully restored Christina’s facial balance, allowing her to close her lips naturally and improving her overall well-being.”
