Soft tissue infection around a skin penetrating osseointegrated implant. A case report.

A case is reported where a female patient with bilateral otosclerosis received a bone-anchored and skin-penetrating titanium implant on which a hearing aid was mounted to improve conductive hearing loss. The patient developed an infection that did not cease despite intensive local treatment and skin-grafting. Eventually the implant was removed. The histological examination of the interface between implant and surrounding bone and soft tissues showed an inflammatory reaction in the superficial parts of the soft tissues whereas the deeper portions of the soft tissues and all of the bone tissue were free of inflammation. It is concluded that it is possible to maintain osseointegration in spite of an aggressive soft tissue infection around the implant.

[Application of Nd-YAG laser in surgical treatment of otosclerosis patients].

The review concerns application of impulse Nd-YAG laser (wave length 1.32 micron) in stapedial operations. Laser beam provides more accurate and less traumatic conduction of complex stages of stapedoplasty: dissection of the limbs of the stapes with preservation of the stapedial muscle, arrest of bleeding from the vestibule mucosal vessels, thinning of the base of the stapes. However, perforation of the base of the stapes by impulse Nd-YAG laser is not safe because of the treat of radiation and mechanical damage to essential structures of the internal ear.

[Evaluation of stapes prosthesis biocompatibility].

We reported patient suffering from otosclerosis, who was reoperated after 18 years. During the reoperation we did not observe any changes of intolerance, but histological examination of removed tarflen prosthesis showed foreign body reaction.

The unilateral stapes gusher.

A stapes gusher is an alarming situation occurring during stapes surgery for mixed hearing loss. It is characterized by the sudden profuse flow of cerebrospinal fluid in the middle ear and external ear canal after opening the vestibule of the inner ear. An adult patient with unilateral stapes gusher is described; he was operated on both ears with a good hearing result on both sides. The stapes on the side with the cerebrospinal fluid leak was malformed, especially in the posterior crus--a finding which may suggest the possibility of a stapes gusher. The small-hole stapedotomy is a safe technique when dealing with a profuse cerebrospinal fluid leak, and it enables the closure of the leak with additional tamponade of the oval niche and the achievement of a good hearing result.
