Suggest Treatment For Hirayama Disease
Laminectomy offers more space for the cord.
Detailed Answer:
Hello again and thanks for the question.
Hirayama disease was prescribed as a separate entity before the MRI invention, so, clinical features are those that matters most.
Surgery offers a permanent immobilization in comparison with cervical braces, and laminectomy is not possible through anterior route so posterior laminectomy is the right choice. Only discectomy and fusion could be achieved by anterior approach.
Laminectomy makes "more" space longitudinally than discectomy, so I agree with you son's opinion about the approach.
Hope I helped you.
I remain at your disposal for further questions and clarifications.
Wishing good health to you and your son.
Take care.
