We read with great interest the correspondence by Piraccini and Byrne [
1] in response to our report of a patient with myofascial pain syndrome (MPS), who underwent rhomboid intercostal block (RIB) at our clinic [
2].
We thank the authors for their valuable comments and opinions. Their article might show a new way for both diagnosis and treatment of MPS due to fascial adhesion. We would like to share the details of long-term pain relief in our patient as additional information.
RIB is a novel interfascial block that has been used to treat MPS in recent times [
2,
3]. MPS is a chronic condition, and few cases might be refractory. MPS can be primary or secondary [
1,
2]. In secondary cases, such as in our patient, interfascial plane blocks might be a good alternative for treatment. However, it is not clear whether they provide short-term or long-term relief. To the best of our knowledge, previous case reports in the literature have described short-term pain relief on using fascial plane block for MPS [
3–
5]. Piraccini and Maitan [
3] performed RIB in a female patient who had fascial adhesions and reported successful results; however, the long-term outcomes are unknown. Similarly, Piraccini et al. [
4] performed an erector spinae plane block (ESPB) for MPS, but the authors emphasize that ESPB provides short-term relief and that fascial plane blocks should be combined with physical therapy.
In our case, we performed RIB using 20 ml of 0.25% bupivacaine with 8 mg of dexamethasone [
2]. The patient was followed up for four weeks. For the first two weeks, we prescribed 25 mg oral dexketoprofen and 8 mg of thiocolchicoside. After four weeks of observation, the patient underwent follow-up once a month. He is still under follow-up. He had no recurrence of MPS in the last 6 months, required no analgesic drugs, and did not undergo physical therapy. He continues his work and daily activities. Our patient might have had fascial adhesions but experienced long-term relief with fascial hydro-dissection and bupivacaine with 8 mg of dexamethasone. Chronic pain is complicated, and interfascial adhesions might play a key role in this complex process. We aimed to treat several steps associated with the pain mechanism by using multimodal analgesia management with hydro-dissection.
The use of fascial plane blocks for MPS is a novel technique. There is a lack of information about long-term results in the literature. Further studies and larger case series are necessary to validate the results.
