The aim of the present study was to evaluate how much a relaxing incision of the galea aponeurotica affects the biomechanical properties of a scalp flap to quantify the surgery-related advantages provided by this procedure. Twenty scalp flaps, created by a reverse-Y incision down and through the galea aponeurotica together with undermining (in...

Post-mastectomy breast reconstruction by the aid of tissue expansion is a reliable and safe procedure, whose major drawback is related to the time requested for its completion, which is mainly due to the formation of a periprosthetic fibrous capsule and the local ischemia determined by the compression of the implant itself on the surrounding...

Background. This article describes an operative technique, based on the use of three galeal flaps anchoring, aimed at reducing the percentage of "stretchback" occurring after performing scalp reduction procedures. Methods. In 12 male patients undergoing a midline scalp reduction procedure, three rectangular galeal flaps, in direct continuity...

Objective. Indications for endoscopic transthoracic upper dorsal sympathectomy are axillary and palmar hyperhidrosis, upper extremities ischemia (due to, e.g., Raynaud's disease), and upper extremities causalgia. Methods. At present, this methodology relies on (at least) double trocar insertion (per side) and/or carbon dioxide insufflation....

Background. The aim of this paper was to present a new technique, the H- shaped splint, for digital flexor tendon repair, aimed at enhancing the biomechanical properties of such repairs as related to resistance to both gap formation and repair failure. Methods. In order to evaluate the gap-formation and failure strengths of the described...

This study shows that topical applications of dimethyl sulfoxid (DMSO) 60% increase the benefits related to the use of intra-operating tissue expansion due to skin lesion excision. This phenomenon is explained by the strong collagen power of DMSO, which breaks both inter-molecular and intra-molecular links of collagen fibres with a possible...

Background. The aim of this study was to test the ex-vivo biomechanical properties of acutely expanded scalp flaps, in order to quantitatively assess the efficacy of acute scalp expansion. Methods. A total of 14 fresh male cadavers were used for the study. In each cadaver, a rectangular (4 × 10 cm), laterally-based flap was designed on each...

Background. The present study was designed to investigate, in a rabbit model, the efficacy of topical application of a solution of hydrogen peroxide (H2O2) 8% + dimethyl sulphoxide (DMSO) 50% in order to reduce ischaemic failure in random skin flaps. Methods. Two parallel, cephalad-based para- midline random cutaneous flap (10x2.5 cm) were...
