Our Clinics’ Treatment
Additional information about the Cellgel method we have introduced in this column.
Cost of the Cellgel method: 1,320,000 yen per area (including tax) to 1,760,000 yen per 5 areas (including tax)
Risks and side effects of the Cellgel method: Transient pain may occur after treatment. Nerve damage is not a zero possibility due to the very nature of the treatment, but there have been no reports of damage so far in either report cases or publications. There is a very small possibility of allergic reactions to local anesthetics. Symptoms may temporarily worsen during the first week or two after treatment. This is believed to be due to the decompression effect of the implant, which retracts the surrounding tissues. In addition, if the disc is almost completely collapsed, treatment may be difficult. The doctor hold a consultation with you during your visit to the clinic to determine the best treatment option for your condition.
