A 2-cycle audit on the feasibility, efficacy and patient acceptance of 21 emergency sphenopalatine artery ligations under local anaesthesia: Our Experience

Sphenopalatine artery surgery for refractory idiopathic epistaxis: Systematic review and meta-analysis

OBJECTIVES

Epistaxis, especially posterior epistaxis, is occasionally refractory to treatment. In these cases, sphenopalatine artery surgeries, including cauterization and ligation, are required. Previous reports have demonstrated treatment results for these procedures but failed to provide high-level evidence. The aim of this study was to quantify the rates of failure and perioperative complications of these procedures by using a meta-analysis technique.

METHODS

We systematically searched electronic databases and identified articles regarding epistaxis, sphenopalatine artery ligation, or cauterization. Pooled rebleeding and complication rates were calculated by using a random effects model.

RESULTS

A total of 896 cases of sphenopalatine ligation or cauterization for epistaxis were analyzed. Pooled rebleeding rates for the entire cohort, cauterization group, and ligation group were 13.4% (95% confidence interval [CI] 10.0-17.8, P < 0.001), 7.2% (95% CI 4.6-11.0, P < 0.001), and 15.1% (95% CI 9.8-22.5, P < 0.001), respectively. Pooled perioperative complication rates for the entire cohort, cauterization group, and ligation group were 8.7% (95% CI 4.9-15.1, P < 0.001), 10.2% (95% CI 3.8-24.5, P < 0.001), and 6.4% (95% CI 1.8-20.9, P < 0.001), respectively.

CONCLUSION

Overall, sphenopalatine surgery for refractory epistaxis is an effective method because of its low rates of failure and complications. Cauterization is more effective than ligation, whereas complications are comparable between the two procedures. Laryngoscope, 129:1731-1736, 2019.

Endoscopic sphenopalatine artery ligation for acute idiopathic epistaxis. Do anatomical variation and a limited evidence base raise questions regarding its place in management?

BACKGROUND

Endoscopic sphenopalatine artery ligation is widely accepted as effective and safe for acute spontaneous epistaxis that is unresponsive to conservative management. As with many new procedures, it has been progressively adopted as common practice, despite a limited evidence base for its efficacy. Early reviews called for comparative trials to support its adoption, but subsequent literature largely consists of case series and narrative reviews. These have attempted to derive an algorithm to establish its place in management, but consensus is still lacking. Intuitively, although there are theoretical objections, an operation regarded as relatively simple, fast and safe hardly seems to demand high-level evidence of efficacy. Rhinologists may be influenced by years of personal experience and success with the technique. However, estimates of the effect size and the added contribution to traditional surgical management are lacking. If the procedure could be shown to dramatically influence outcome, it should be standard practice and indispensable for all patients requiring operative intervention.

OBJECTIVES

This paper systematically examined the literature, appraising the anatomical basis for such an approach and evidence for its efficacy. It questions whether any units unable to consistently offer endoscopic sphenopalatine artery ligation should be undertaking surgical management of acute epistaxis.
