De Novo Malignancies After Kidney Transplant: Where Do We Stand and Does the Head and Neck Region Require More Caution?

Objectives: The aim of this study was to investigate the characteristics of de novo malignancies arising in kidney transplant recipients followed in a tertiary hospital in Turkey and to examine the tumors in the head and neck region as a subgroup.

Materials And Methods: Data from kidney transplant recipients treated at our institution between January 2010 and July 2022 were retrospectively analyzed in this single-center study. Data regarding malignancies were noted according to the pathologists' reports.

Reconstruction of Orbital Floor With Auricular Concha.

Orbital floor fractures of varying sizes commonly occur after orbital injuries and remain a serious challenge. Serious complications of such fractures include enopthalmos, restriction of extraocular movement, and diplopia. There is a dearth of literature that can be applied widely, easily, and successfully in all such situations, and therefore there is no consensus on the treatment protocol of this pathology yet.

Comparison of Subciliary Approaches in Orbito-Zygomatic Fractures: Skin Flap Versus Skin-Muscle Flap.

Background: Because of the complications of classical subciliary incision, some modified subciliary approaches have been described in recent literature.

Objectives: The aim of this study was to compare 2 commonly used subciliary approaches according to development of postoperative complications (scar formation, and ectropion).

Materials And Methods: Ninety patients were included in this retrospective study.

Orbicularis oculi myocutaneous advancement flap for upper eyelid reconstruction.

Background: Reconstruction of large full-thickness defects of the upper eyelids is challenging because of their complex anatomy and specialized functions. The authors present and discuss a new, simple surgical technique for upper eyelid reconstruction. This is a single-stage procedure and has produced satisfactory to excellent results in the authors' patients.

Use of the medial side of the knee skin as a free flap: saphenous flap.

Background: The knee region is a good free skin flap donor site, as it has minimal subcutaneous tissue and provides a hidden donor site. Acland et al. first used the skin over the medial side of the knee as a "saphenous flap" based on the saphenous branch of the descending genicular artery.

Reconstruction of the columella with bilateral nostril sill flaps.

The treatment of total columellar defects is very difficult, and there is not any first choice in reconstruction of these defects. Various techniques have been reported for this purpose. Each technique has its own drawbacks, and few can be performed in one stage.

Urethral advancement for recurrent distal hypospadias fistula treatment.

Hypospadias fistula may be persistently recurrent in some patients. In distal hypospadiac fistula cases, carrying the fistulous opening to the glans tip may be possible with extensive urethral mobilization and advancement. In 9 patients who were operated for urethrocutaneous fistula, we used the urethral advancement technique.

Rat penis as a replantation model.

The aim of this study is to assess the feasibility of rat penile replantation as a new microsurgical training model. The study was performed in 2 parts. ANATOMIC STUDIES: Fifteen Wistar albino rats were used to study and document the penile vascular anatomy.

Use of medial arm skin as a free flap.

Background: Free transfer of the medial arm flap has not gained popularity despite the hidden donor-site scar as well as the hairless and elastic skin. This may be because of variations in vascular anatomy, leading to confusion during dissection of the flap.

Methods: In five preserved cadaver arms, the vascular pattern of medial arm skin was examined.

Reverse-flow first dorsal metacarpal artery flap for index fingertip reconstruction.

Dorsum of the hand is an ideal skin-flap donor site for coverage of hand or finger defects. We elevated 8 reverse-flow first dorsal metacarpal artery flap in 9 patients for soft-tissue cover of index fingertip injuries distal to distal interphalangeal joint with exposed bone. In 3 patients, the digital branch of the superficial radial nerve was coapted to the digital nerve.

Versatility of the lateral arm free flap in various anatomic defect reconstructions.

The free lateral arm flap may be harvested as a fascial, fasciocutaneous, or osteofasciocutaneous flap. Simultaneous flap elevation with preparation of the recipient site, easy dissection, minimal donor-site morbidity, and a constant vascular anatomy with long pedicle are advantages of the flap. In this study, the authors present 18 patients operated on between January, 2002 and August, 2003 in whom 18 free lateral arm flaps were utilized.

A new epineural nerve repair technique with external metallic circle.

Background: Despite the existence of various nerve coaptation techniques, functional results of nerve repair are still inadequate. Potential benefits of developing modified coaptation techniques cannot be disregarded.

Methods: The authors report a new coaptation technique in which the epineural sutures were performed with an external metallic circle to increase the coaptation surface.

External metallic circle in hepaticojejunostomy.

Background: Biliary-enteric anastomosis especially Roux-en Y hepaticojejunostomy is frequently used for biliary diversion in benign biliary strictures. In this study, we present the results of hepaticojejunostomy with external metallic circle.

Methods: Hepaticojejunostomy with external metallic circle were performed in eight male Sprague-Dawley rats.

Free microvascular transfer of coccygeofemoral muscle in rabbits.

A new experimental free flap model, the cocygeofemoral muscle flap of the rabbit, is introduced in this study. The coccygeofemoral muscle is a superficially located triangular muscle originating from the sacrum and inserting into the lateral condyle of the tibia, and it abducts the thigh. Anatomical dissection and microangiographic studies revealed that it has a major and a minor pedicle, the former originating from the caudal gluteal artery, and the latter originating from the caudal femoral artery.
