“…When perforating stapedotomy in humans, the structures that are most exposed are the saccule and the utricle, whereas fenestration in the basal turn of the guinea pig cochlea, however, involves a higher risk to structures of organ of Corti like the basilar membrane, the stria vascularis, the outer and inner hair cells, etc. In addition, the guinea pig cochlea has been reported to be 10 times sensitive to acoustic trauma than the human cochlea [21]. Since this probably results in higher vulnerability of these anatomic structures in the animal experiment, inner ear damage is more likely to induce from laser application in our animal model than would be the case when irradiation in the human stapes footplate and the vestibule, and therefore overestimate the detrimental effects we have seen.…”

“…Several studies have reported on the reliability of procedures in which different instruments are used, such as manual perfo rators, electric or pneumatic drills and. last ly, laser [2,5,9,10]. According to various reports, no difference is believed to exist as far as concerns the hearing results, even though it is assumable that the degree of the trauma to the inner ear varies according to which instrument is used for creating the hole in the stapedial footplate.…”

The possible occurrence of inner-ear trauma linked to stapedotomy was studied by scanning electron microscopy of the medial (or labyrinthine) side of human stapedial footplates after performing a hole with different instruments. The anatomic variations induced experimentally by the different procedures are presented in detail and discussed. Manual instruments were shown to induce irregularities on the rim of the hole, whilst the utilization of either electric or pneumatic drills produced more regular margins. Finally, laser-produced holes were also examined. Rather neat rims were observed, but the thermal effect produced by this device has to be considered the major parameter involved in a possible inner-ear postoperative trauma.

“…Im Einzelnen sind dies die im sichtbaren Wellenlängenbereich strahlenden Argon-und KTP-Laser sowie der im Infrarotbereich strahlende CO 2 -Laser [1,6,7,9,12,14,15,17,28,29,30,32,34,36,39,45,53]. Unter den gepulsten Lasersystemen scheint der Er:YAG-Laser die geeignetste Wellenlänge für den Einsatz in der Mittelohrchirurgie zu besitzen.…”

In addition to hearing aids, stapesplasty represents the standard treatment of otosclerosis-induced hearing loss. In this procedure, the stapes superstructure is replaced by a prosthesis that is attached to the long process of the incus and communicates through a perforation in the footplate with the perilymphatic space of the inner ear. The removal of the stapes superstructure and perforation of the footplate are the critical steps of this surgical procedure. With the introduction of laser-assisted perforation techniques, the surgical safety of this method has been improved compared to conventional techniques. KTP, argon, as well as diode, Er:YAG and CO(2) lasers are used for stapedotomy. By using the CO(2) laser in conjunction with a scanner system, the number of laser applications required for the perforation of the footplate has been markedly reduced. In contrast to other systems, a more reproducible perforation diameter of the stapes footplate is achieved with a CO(2) laser equipped with a scanner. Complications such as uncontrolled leakage of perilymph, irradiation of inner ear structures or the occurrence of pressure waves with subsequent damage to the inner ear can be reduced by using a CO(2) laser. In this review, the surgical technique of CO(2) laser stapedotomy, including clinically established variants and paying particular attention to the one-shot technique, are described and discussed in comparison to other laser systems.
