Pneumolabyrinth due to late complications of stapes surgery is a rare entity. Symptoms may include various degrees of hearing loss, tinnitus and dizziness. We report the case of a 67-year-old patient who developed a unique pneumolabyrinth variant affecting the vestibule, cochlea and semicircular canals 28 years after stapedectomy. The patient presented with intractable paroxysmal positional vertigo of the lateral semicircular canal. The pneumolabyrinth was visualized by means of high resolution computed tomography. Exploratory tympanotomy findings were consistent with a perilymphatic fistula. One year after surgical treatment the subject was free of vertigo spells. Pathogenetic mechanisms are discussed.

    We describe a new arthroscopic technique to repair the foveal attachment of the TFCC with the use of a suture anchor, which is indicated for class 2 and 3 TFCC peripheral tears, instead of an open repair. This technique requires a dedicated working portal to approach the fovea ulnaris. This Direct F...

    We compared the Italian and the German DRG systems regarding hand surgery with an emphasis on reimbursement of clinical cases. The 15 most common hand surgical diagnoses and their corresponding operative treatment in our clinic in 2009 were processed using a DRG grouper. The underlying data were tra...
