Progression
Parry Romberg syndrome is characterized by progressive facial changes that typically begin in the middle of the face, specifically around the nose, upper lip, cheeks, or upper jaw. Over time, the impact of the syndrome extends outward on the affected side, affecting areas such as the eyes, eyebrows, ears, and lower jaw. In more severe cases, the chin may also be affected. As the syndrome progresses, these areas gradually become sunken as the fat, muscle, cartilage, and bone undergo shrinkage. A noticeable line often forms down the center of the face, demarcating the affected side from the unaffected side.
The Impact of Parry Romberg Syndrome on the Mouth and Teeth
Parry Romberg syndrome not only affects the facial appearance but can also have significant implications for the mouth and teeth. Typically, the abnormalities in the mouth and teeth occur on the same side as the facial deformities. One noticeable effect is the twisting of the lip, which can lead to the abnormal exposure of the teeth.
Moreover, the tongue may also be affected by the deterioration caused by Parry Romberg syndrome. Additionally, individuals with this syndrome are more susceptible to spontaneous fractures in the lower jaw. Furthermore, the muscles responsible for chewing may experience involuntary contractions, leading to difficulties in the proper functioning of the jaw.
In children diagnosed with Parry Romberg syndrome, the eruption of teeth tends to be delayed compared to normal development. This delayed eruption can cause concerns and may require intervention from dental professionals.
