Effect of electromagnetic field induced by radio frequency waves at 900 to 1800 MHz on bone mineral density of iliac bone wings.

Objective: Telecommunication has gained a different meaning in daily life with the introduction of the mobile phone system. However, electromagnetic pollution has increased in parallel to this improvement. In this study, we aimed to investigate the effects of electromagnetic waves emitted from cellular phones operating at a frequency of 900 to 1800 MHz on the bone mineral density of the human iliac bone wings, which are the most common carriage sites for mobile phones.

Place of sagittal split osteotomy in mandibular surgery.

With the development of craniofacial surgery, today sagittal split mandibular osteotomies are frequently used for the treatment of mandibular deformities with modifications and different fixation techniques. In clinics, 57 patients are evaluated in this study. Of these patients, 35 were male, 22 were female, and their ages were between 17 and 47 years (on average, it was 23 years).

Examination of the skin perforators of the posterior tibial artery on the leg and the ankle region and their clinical use.

Background: There are many treatment alternatives for reconstruction of leg and foot defects. One of these treatment alternatives includes local flaps. A detailed understanding of the blood flow of the leg region is essential for producing new alternatives for the reconstruction of defects of this region.

Multi-centric basal and squamous cell skin malignancies of the craniofacial region.

The etiology of skin malignancies is evaluated as multi-factorial. The human phenotype, syndromes, precursor lesions, and immunologic differences play as risk factors as well as environment. Twenty-seven patients with multi-centric skin malignancies investigated as if having predisposing syndromes.

Evaluation of osteogenic and chondrogenic activities of prefabricated periallografts.

Reconstruction of cartilage and bone defects has always been a challenging problem for the surgeon. Basic elements that are responsible for the repair process of these tissues are periost and perichondrium. Although several methods for the use of periost and perichondrium are proposed in the literature, the osteogenic and chondrogenic capacities of these tissues were shown to be the most important factor for a successful outcome.

Osteogenic capacities of periost grafts, periost flaps and prefabricated periosteal flaps: experimental study.

Reconstruction of the bone defects due to various causes is still one of the challenging problems in plastic and reconstructive surgery. Periosteum is accepted to be the essential source for the repair of the bone tissue, which constitutes the basis of the support and the mobility functions of the surrounding tissues. Periosteal grafts and flaps have been used for various purposes by numerous techniques.

Reconstruction of heel defects with a proximally based abductor hallucis muscle flap.

The main goals of reconstruction of plantar defects include appropriate soft tissue coverage to facilitate weight bearing, and sufficient blood supply to prevent osteomyelitis. This retrospective study presents the clinical results of 11 patients who received a proximally based abductor hallucis muscle flap for coverage of calcaneal defects. The mean patient age was 43 years (range, 23-69 years).

Anatomy of the platysma muscle and the evaluation of it for the reconstruction of facial defects.

Reconstruction of the defects with various flaps is the main issue in plastic and reconstructive surgery. Tissues used for the repair of the defects of the face should be convenient for this most important aesthetic unit. Color, elasticity, and volume of the transferred tissues have the utmost importance for successful results.

Plasmacytoma of the hard palate.

Multiple myeloma is a systemic malignant disease and is associated with a poor prognosis. It is characterized by neoplastic proliferation of plasma cells involved in the production and secretion of monoclonal immunoglobulins (M proteins). It is generally a disseminated disease involving many bones.

Axial pattern composite prefabrication of high-density porous polyethylene: experimental and clinical research.

Currently, various alloplastic materials are being used for reconstruction of three-dimensional structures, and high-density porous polyethylene is so far the best and the most commonly used material. Various indications for high-density porous polyethylene have been defined for closure of craniofacial defects, correction of congenital anomalies, and aesthetic augmentations. A common property of various studies published so far is that after being fixed to the bone or underlying structures, high-density porous polyethylene has been covered primarily or by skin flaps.

Angiokeratoma circumscriptum.

Angiokeratoma circumscriptum is one of five types in the group of the angiokeratomas. These lesions are usually present at birth and are not related with systemic diseases. Angiokeratoma circumscriptums are hyperkeratotic papules or nodules occurring frequently unilaterally on the leg.

What is new in the treatment of hypospadias?

Hypospadias is a congenital anomaly characterized by a ventrally placed urethral meatus in a more proximal position on the midline than its normal position in the glanular part of the penis. In 1961, C. E.

Incidental idiopathic calcinosis cutis in a rhytidectomy patient.

Calcinosis cutis, deposition of insoluble calcium salts in cutaneous tissues, is an uncommon disorder. This condition can be classified as metastatic, dystrophic, idiopathic, and iatrogenic based on the pathogenesis of the deposition. Whereas dystrophic calcinosis cutis is a fairly common condition, idiopathic cases are very rare.

Soft tissue hemangioma formation within a previously excised intraosseous hemangioma site.

Intraosseous hemangiomas are rare benign lesions, occurring often in verbrata and skull. These lesions can present in the head and neck region being the next most common site with a predominance of the mandible. Herein we report a patient who experienced a soft tissue hemangioma occurring at the previous surgical site three years after the first operation.

Total lower lip reconstruction using sensate composite radial forearm flap.

In modern plastic and reconstructive surgery, shape and function must be considered together. These are the most important goals of any operation. There are a lot of techniques that have been reported for total lower lip reconstruction.

Anatomicohistologic study of the retaining ligaments of the face and use in face lift: retaining ligament correction and SMAS plication.

Plastic surgeons have sought to improve nasolabial folds, jowls, jaw lines, and cervical contour with face-lifting procedures that are abundant in the literature. The retaining ligaments of the face support facial soft tissue in normal anatomic position, resisting gravitational change. As this ligamentous system attenuates, facial fat descends into the plane between the superficial and deep facial fascia, and the stigmata of facial age develop.

Reconstruction of facial defects with superficial temporal artery island flaps: a donor site with various alternatives.

Color and texture match is crucial in reconstruction of facial tissue defects. Between March of 1997 and July of 2000, island flaps based on the parietal, anterofrontal, centrofrontal, posterofrontal, and superior auricular branches of the superficial temporal artery were used in the reconstruction of tissue defects localized on different regions of the face in 28 patients. According to the size and the location of the defect, the flap was selected.

Intraosseous hemangioma of the mandible: a case report and review of the literature.

Intraosseous hemangiomas are benign lesions, occurring often in vertebra and skull. These lesions can present in the head and neck region being the next most common site with a predominance of mandible. There are approximately seventy intraosseous hemangiomas of mandible in literature reported to date.

Clinicopathological evaluation of parotid gland tumors: a retrospective study.

Two hundred and thirty sequential parotid tumors seen from March 1985 to 1995 were reviewed for their clinical presentation, diagnostic evaluation, pathological diagnosis, treatment modalities, and age and sex distribution. An asymptomatic mass was the most common clinical presentation. All of the operations were performed by the same surgical team.

T-incision technique in distal hypospadias: a modification of meatal advancement and glanuloplasty.

Hypospadias is among the most common of the congenital anomalies. Distal hypospadias refers to an orifice in the distal third of the penile shaft. Correction of distal hypospadias requires different techniques, depending on the location of the meatus.
