Presentation and Optimal Management of Anterior and Central Skull Base Osteoradionecrosis: Systematic Review and Meta-Analysis.

OBJECTIVE

To conduct a systematic review and meta-analysis to compare the efficacy of conservative treatment versus surgical debridement versus debridement followed by vascularized tissue coverage to provide evidence-based guidance on the management of osteoradionecrosis of the anterior and central skull base.

DATA SOURCES: PubMed, Embase, and Cochrane Library.

REVIEW

METHODS

Systematic review and data sources including PubMed, Embase, and Cochrane Library were accessed using PRISMA guidelines. Meta-analysis was performed on treatment type and resolution of osteoradionecrosis.

RESULTS

A total of 13 articles met the inclusion criteria. Patients were categorized into conservative medical treatment versus surgical treatment. Conservative treatment included patients undergoing hyperbaric oxygen therapy, antibiotics, pentoxifylline-tocopherol-clodronate, or a combination of the three. Eight out of 197 patients treated with conservative therapy had resolution of symptoms (4.1%) while 135 of 188 patients treated with surgical intervention had resolution of symptoms (71.8%). Of these, 104 patients (91.2%) in the vascularized tissue group experienced resolution of symptoms.

CONCLUSION

Surgery was superior to medical treatment alone in the resolution of skull base osteoradionecrosis. Vascularized surgical treatment fared significantly better when compared with both surgical debridement only and/or medical treatment. Our findings suggest that surgical treatment should be considered earlier in patients with skull base osteoradionecrosis to prevent severe or fatal sequelae.
