- Bone pain
- Severe headache
- Deafness - This is due to the constriction of the VIII cranial nerve, the vestibulocochlear nerve in its foramen as the bone closes in on it.
- Facial paralysis- Here again the closure of the foramen is the cause for paralysis. It could affect just one side of the face or both sides depending on which foramen is involved.
- Spinal deformities
- Bowing of the legs
- Broadening and flattening of the chest
- Patients assume a 'simian' appearance due to the uncontrolled deposition of bone.
- Teeth become enlarged, loosen and may shift their positions in the jaws.
- The lips are too short to cover the huge proportion to which the jaws have grown.
- Fractures are uncommon and when they do occur, the healing is normal.
