Based on their experience and on a review of the literature, the authors study the surgical aspects of the undescended testis. A precise definition excluding the retractile testis is essential. Although the understanding of the pathogenesis remained incomplete, the present data give support to an early orchidopexy performed by a specialized surgeon following the failure of a human chorionic gonadotropin test.

Total hip arthroplasty (THA) is a very successful operation. Once the problem of implant fixation was solved with the use of bone cement, the next development steps focused on improving the bearing. Weber, a Swiss surgeon, introduced the first modular heads in THA.

Craniosynostosis causes functional and aesthetic problems that require fronto-orbital advancement in patients to correct the cranial deformity and to prevent functional problems due to increased intracranial pressure (ICP). In this study, demographic information, operative details, preoperative clinical findings, and postoperative outcomes were reviewed for 106 craniosynostosis patients with at least 1 year of follow-up. Many factors such as functional losses due to increased ICP before surgery, resynostosis, fronto-orbital relapse, surgical complications and aesthetic results were compared in syndromic and non-syndromic patients.

Insufficient keratinized mucosa is a common clinical problem. Although there is no consistent data on the long-term success of implant restorations relative to the presence or absence of peri-implant keratinized mucosa, it is widely accepted that the presence of keratinized mucosa width<2 mm is associated with increased biofilm accumulation, soft-tissue inflammation, and mucosal recession. Free gingival graft (FGG) is the standard surgical intervention for augmenting the width of keratinized gingiva.

The anatomical structure of the gingival papilla around the implant is special, and it is difficult to recover after injury. The reduction of its height will have a negative impact on function and esthetics, and it is one of the many problems in implant treatment at present. This paper analyzes the influencing factors of implant gingival papilla height from three aspects: anatomical factors, implant surgical design and implant restorative design, including the classical influencing factors such as the shape of natural teeth, interproximal distance between the implant and the adjacent tooth, soft tissue grafting, and contour of implant restorations, as well as the hot and controversial influencing factors in recent years such as the thickness of soft tissues around the implant, the implant surgical timing, the flap design, and the surgical incision, in order to provide reference for clinicians in the process of implant treatment for gingival papilla preservation and reconstruction.

Revision hip arthroscopy is increasingly common and most often performed to treat residual femoroacetabular impingement caused by cam under-resection. Unfortunately, other pathologies encountered during revision hip arthroscopy are more difficult to treat, including capsular deficiency, labral deficiency, adhesion formation, and/or cam over-resection. When encountered, these various pathologies should be comprehensibly corrected with the goals of restoring anatomy, re-establishing the hip fluid seal, and ensuring impingement-free motion.
