✦ Synopsis
Objectives:
The objective of this study was to analyze a new technique, CO2 laser-assisted posterior semicircular canal ablation (LAPSCCA), in the treatment of refractory benign paroxysmal positional vertigo.
Study Design: Prospective study of patients with disabling BPPV who failed conservative therapy.
Methods: Patients noted to have been treated with at least three Epley maneuvers without success and continuing to have disabling symptoms were enrolled in this study. Patients underwent pre-and post-operative electronystagmography. The surgical technique is modified from Parnes 1 and involves plugging each end of the fenestrated posterior semicircular canal with bone grafts and fibrin glue. The CO2 fiberoptic (Omniguide) laser is then used at a setting of 2 watts to incise between the cut ends of the canal to completely section the membranous labyrinth.
Results: All six patients had excellent relief of positional vertigo symptoms.
Conclusions:
LAPSCCA is an excellent treatment option for patients with intractable BPPV.
