Diodes Laser in Ent Surgery

LASER in the otology field was used to perform tympanotomy and for the placement of ventilation tubes, vaporization of horny pearls and adhesion in the eardrum, remobilisations and ossicular modelings, “spot-welding”; in this field the most argued area of applicability of LASER is the surgery of the otosclerosis. The otosclerosis treatment with surgical LASER started with Perkins and Di Bartolomeo in 1980 using Argon LASER; afterwards were used also other sort of LASER: CO2, KTP. Laser benefits in the surgical therapy of otosclerosis are the bleeding control and the limitation of the handling of the platina reducing the risk of “floating platina” and acoustic vibratory trauma. These advantages allow to optimize the functional result and to reduce risks of cochlear damage connected with surgical treatment. The ideal property of tissue interaction of the laser radiation in the otosclerosis surgery is the laser’s energy absorption of the platina, that allows the vaporization and avoids the perilymph thermal dispersion. The modality of supply of the pulsate energy enables the tissue cooling between the pauses and reduces the risk of thermal damage of the surrounding structures. The argon laser is used for vaporize the stapedius tendon, the posterior crus of the stapes, as Acta Medica Mediterranea, 2011, 27: 79
