In revision surgery of joints, high-frequency electrocauterization instruments are used for homeostasis and dissection of soft tissue. If there is contact of these instruments with the metal implants, flashover can occur. This can lead to thermal microstructural changes in the material and as a consequence may reduce the fatigue strength of the implant. Four cases of hip revision surgeries were analysed. In all cases flashovers occurred and secondarily, the titanium hip endoprosthesis stem broke in the neck section of the prosthesis. The conducted investigations showed that contact between the high-frequency instrument and the anterolateral aspect of the endoprosthesis neck had occurred. Electrothermal implant damage was found in the broken area. If in hip revision surgery the stem is not to be replaced, contact between high-frequency instruments and the metal implant should be avoided.

Background: Several studies have demonstrated the interest in patient-specific custom cutting guides in total knee arthroplasty (TKA), but clinical improvement remains debated. The purpose of this study was to evaluate the functional outcomes (Forgotten Joint Score, FJS) of patients undergoing individualized TKA compared with those receiving off-the-shelf (OTS) implants, both using patient-specific cutting guides with personalized alignment over a minimum follow up period of 12 months. We hypothesized that individualized TKA demonstrates significantly better functional outcomes than OTS TKA (FJS and percentage of patients reaching the minimum clinically important difference).

Background: To analyze the clinical characteristics, complications and patients satisfaction of MIP hypospadias variant.
Methods: A retrospective analysis was performed for 31 patients with MIP admitted to our hospital from January 2008 to February 2023. All enrolled patients underwent telephone follow-up and a survey was conducted on the satisfaction of patients and their families.

Purpose: Tympanoplasty is a surgical procedure performed to cure middle ear infections and restore normal middle ear function. It is one of the most common procedures in otological surgery. Since Wullstein described tympanoplasty, the microscope has been a widely used surgical tool in otological surgery.

Purpose: The escalating number of endoscopic skull base procedures necessitates exploring additional materials to reduce postoperative cerebrospinal fluid (CSF) leaks in revision or staged surgeries. This study evaluates the effectiveness of reused nasoseptal flaps (NSFs) in such clinical scenarios.
Methods: A retrospective review was conducted on patients who previously underwent surgery involving NSFs and later had revision or secondary skull base surgeries via endoscopic endonasal approaches (EEAs) at a tertiary medical center.

Purpose: Acute acoustic trauma (AAT) is a sudden sensorineural hearing loss (SNHL) due to exposure to high intensity impulse noise. There are no acceptable treatment guidelines, although several studies showed steroids could be effective in restoring hearing levels. A recent report suggested that steroids combined with hyperbaric oxygen therapy (HBOT) are a superior regiment for AAT.
