Reoperation Following Primary Greater Occipital Nerve Decompression Surgery: Incidence, Risk Factors and Outcomes.
Plastic and Reconstructive Surgery 2024 April 10
BACKGROUND: Although nerve decompression surgery is an effective treatment for refractory occipital neuralgia (ON), a proportion of patients experience recurrence of pain and undergo reoperation. This study analyzes the incidence, risk factors, and outcomes of reoperation following primary greater occipital nerve (GON) decompression.
METHODS: 215 patients who underwent 399 primary GON decompressions were prospectively enrolled. Data included patient demographics, past medical and surgical history, reoperation rates, intraoperative findings, surgical technique, and postoperative outcomes in terms of pain frequency (days/month), duration (hours/day), intensity (scale 0-10), and migraine headache index (MHI). Bivariate analyses, univariable and multivariable logistic regression analysis was performed.
RESULTS: 27 (6.8%) GON decompressions required reoperation with neurectomy at a median follow-up time of 15.5 months (9.8-40.5). Cervical spine disorders on imaging that did not warrant surgical intervention (OR, 4.88; 95% 1.61-14.79; p<0.01) and radiofrequency ablation (RFA) (OR, 4.20; 95% CI, 1.45-15.2; p<0.05) were significantly associated with higher rates of reoperation. At 12 months postoperatively, patients who underwent reoperation achieved similar mean reductions in pain frequency, duration, intensity and MHI, as compared to patients who underwent only primary decompression (p>0.05).
CONCLUSION: Patients with ON who have a history of cervical spine disorders or RFA should be counseled that primary decompression has a higher risk of reoperation, but outcomes are ultimately comparable.
