Following several years of experience with a newly designed spectacle-supported ptosis crutch for ptosis and blepharospasm, the author has developed a new approach to these conditions. In mild to moderate blepharospasm cases, the spectacle-supported prosthesis can still produce satisfactory results. However, in moderate to severe blepharospasm, the force of the spasm moves the entire device forward and downward, making it ineffective or too uncomfortable to wear. To create greater stability and a more effective counterforce to the blepharospasm, the author has developed a simple headband-supported device which does not use a spectacle frame for support. This new prosthesis is constructed of varying diameters of spring tempered diamond drawn stainless steel orthodontic wire, partially or completely covered by Teflon tubing. A silicon rubber cylinder is placed over the center which becomes a bridge and the main support for the device. An elastic head band completes the prosthesis.

The authors evaluate the different procedures for breast reconstruction in order to determinate the best indication of each technique. From January 1983 to June 1992, 196 reconstructions for breast cancer using implants, including 100 immediate and 96 delayed, were performed. Different types of breast implants were used in this period: in 1983-84 46 double lumen prostheses were performed, in 1985-86 34 Radovan temporary tissue expanders, from January 1986 to June 1991 115 Becker and Gibney permanent tissue expanders and 8 microstructured prostheses. Due to unavailability of silicon-gel implants, from January to June 1992 12 breast reconstructions with saline temporary tissue expanders were performed. In the patients with radical mastectomy 39 latissimus dorsi muscular flaps were carried out for implant coverage. In the same decade 204 breast reconstructions using Rectus abdominis myocutaneous (TRAM) flaps, including 201 delayed and 3 immediate were performed. It can be concluded that the implants are first choice for small or medium size breast, with light ptosis, in immediate reconstruction and when the patients refuse harder surgical procedures. On the contrary the autologous tissue, such as TRAM flap, can be used in patients with redundant abdomen, with controlateral large and ptotic breast and in delayed reconstruction.

Breast reconstruction is an important step for patients after mastectomy. In our Department for immediate reconstruction, smooth or textured temporary tissue expanders filled with saline solution or permanent expandable implants (PEI) with silicon gel saline solution or soyabean oil are usually used. Only in a few selected cases reconstruction using autologous tissues are performed. Delayed reconstruction is performed using autologous tissues: Transversus Rectus Abdominis Myocutaneus Flap (TRAMF) or Latissimus Dorsi flap (LD). The choice between reconstruction with prostheses or muscular flaps depends on previous demolition, local skin condition, contralateral breast size and ptosis, body structure, medical problems, patients' wishes and expectation. Following the legislation defining the privatisation of Italian Health Care Structure and in particular the Decree of December 14, 1994, the need to accurately assess the costs incurred for surgical operations is very important. The aim of this study is to evaluate the clinical limits of each surgical technique and their cost in order to optimize the cost-benefit relationship.

Fibrosis of the extraocular muscles can be an acquired or congenital disorder (CFEOM). The congenital disorder(1) is a complex strabismus with congenital restrictive ophthalmoplegia with or without ptosis. The surgery is challenging because the eye muscles are replaced by fibrous tissue or fibrous bands and in most cases the results are not satisfactory. We present the first case report of unilateral CFEOM with palpebral adherence and hypotropia, which was managed with our technique of a silicon plate implant on the orbital floor. The purpose of the implantation of the silicon plate in the orbital floor is to improve the hypotropia caused by CFEOM.

Today's gold standard in the treatment of infrasaccal primary acquired nasolacrimal duct obstruction (PANDO) is external dacryocystorhinostomy (DCR), a relatively invasive procedure that can be performed after failure of recanalizing treatments. However, with progress in the field of diode laser technology, new approaches have emerged. Laser-assisted transcanalicular DCR with subsequent bicanalicular silicon intubation is a new option showing great promise as a viable minimally invasive procedure. Under permanent endoscopic visual control from the nasal cavity, a diode laser fiber is inserted into the lacrimal sac and laser energy is applied to create a bony ostium between the lacrimal sac and the nasal cavity. Since no skin incision needs to be made, advantages of this method comprise the sparing of the skin as well as the medial palpebral structures and the physiological palpebral-canalicular pump mechanism. The duration of surgery as well as reconvalescence is generally shorter than with external DCR. Complications include silicon tube prolapse, mild swelling and, rarely, canalicular infection and thermal injury. One-year functional success rates, defined as complete resolution of symptoms and ostium patency, are high, yet still range behind those of external DCR. However, secondary external DCR after failure of laser-assisted DCR can be performed without difficulty. Thus, laser-assisted transcanalicular DCR is a valid option that should be considered as a second-step procedure after failure of recanalization procedures and before external DCR.

Orbital implant exposure may be the most common complication after evisceration surgery with orbital implantation. Management of implant exposure is a vital issue for oculoplastic surgeons. We present the case of a patient with nontraumatic eyeball rupture receiving dermis-fat graft after early implant exposure. The present case with multiple penetrating keratoplasty history underwent emergent evisceration and silicon sphere implantation due to nontraumatic eyeball rupture with severe uvea prolapse. The surrounding corneal tissue of the rupture aperture was almost unidentified before the operation. Deep superior sulcus syndrome and orbital implant exposure developed 2 months after the operation; hence, orbital reconstruction and dermis-fat graft transplantation were performed. Orbital reconstruction and orbital implant exposure management are discussed in the content.
