Background And Objective:
To assess the utility of the CO(2) Flashscanner laser for treatment of selected middle ear diseases other than otitis media with effusion (OME) and acute otitis media (AOM).
Study Design/Materials And Methods:
A retrospective review of the records of 144 patients treated with the OtoLAM((R)) device, a Flashscanner laser, between July 1, 1998, and February 29, 2000. Patients treated for AOM or OME were excluded.
Results:
Data are presented on 11 patients (17 ears). Four indications were identified: Elimination of middle ear fluid before auditory brainstem response with or without otoacoustic emission testing (ABR +/- OAE), barotrauma, eustachian tube obstruction, tympanocentesis when a culture of middle ear fluid was deemed necessary. All tympanic membranes (TM) healed.
Conclusions:
Fenestration of the TM can be accomplished for both diagnostic and therapeutic purposes. Laser assisted tympanic membrane fenestration seems to be effective in the management of middle ear fluid before ABR +/- OAE, barotrauma, eustachian tube dysfunction, and for tympanocentesis.
