Role of otoscan-assisted laser myringotomy in hyperbaric oxygen therapy.

Patients undergoing hyperbaric oxygen (HBO2) therapy often experience middle ear barotrauma. Not infrequently this disrupts therapy and may require myringotomy tube placement. A new, simple, office-based procedure known as OtoScan Laser Assisted Myringotomy (OtoLAM) provides temporary middle ear ventilation, which offers significant potential benefis for HBO2 patients. Five patients whose middle ear disease complicated their HBO2 therapy have undergone nine OtoLAM procedures in 11 ears. All patients tolerated the procedure without complications and immediately returned to HBO2 treatment. Based on this preliminary experience, we recommend OtoLAM for selected HBO2 patients with problematic middle ear dysfunction.
