Question Mark Ear: An Unusual Anomaly and a Novel Surgical Technique for Reconstruction.

The question mark ear is a rare abnormality characterized by a cleft between the helix and the earlobe, resulting in a protrusion of the upper part of the ear. The severity of this ear malformation can range from a minor notch in the helix to a complete separation of the helix and the earlobe. In this study, we present a case of a patient with a moderately severe right-sided unilateral question mark deformity.

In this single-center study, we analyzed a retrospective cohort of patients with diabetic foot infections (DFIs) between 2011 and 2020. The first and second five-year periods were compared. A poor prognosis was defined as a primary composite end point including re-infection, major amputation, or mortality at six months.

[Clinical Characteristics of Mild-Moderate COVID-19 Patients and Risk Factors for the Development of Pneumonia].

Limited data exists to date on the predictors for the development of pneumonia in patients with mild and moderate coronavirus (COVID-19). In this study, it was aimed to evaluate the demographic characteristics and clinical findings of mild and moderate COVID-19 and to determine the risk factors for the development of COVID-19 pneumonia in patients admitted to the pandemic outpatient clinic of a university hospital. A total of 414 patients with laboratory confirmed COVID-19 were included.

Effects of Cigarette Smoke on Fat Graft Survival in an Experimental Rat Model.

Introduction: A fat graft is the closest thing to being the ideal soft tissue filler. Although it has many advantages, reliability of late-term survival is a never-ending debate. Although there are observational studies that research the effect of cigarette smoke on fat graft take in clinical setting, there has not been an objective experimental animal study on the affect of smoking on fat graft survival.

The New Anatomical Classification System for Orbital Exenteration Defect.

Background: The unique anatomy of the orbita and the different behavior of each malignant tumor cause us to perform the various types of orbital exenteration that yields to varying defect each of which has own specific demands in terms of the reconstruction. Current classification of orbital exenteration defects seems not to be adequate to provide detailed description. This study reviews 50 exenteration defects to offer a more effective anatomical classification system.

Origin, Reality, and Clinical Importance of the Arcade of Struthers: An Anatomic Study.

The literature contains confusing and opposing views about the naming, prevalence, anatomic structure, and clinical significance of the arcade of Struthers. The conflicting rates of arcade (between 0% and 100%) prevalence found in the literature may be due to the varying definition of the arcade among the authors, as well as the dissection method. The present study aims to examine the structure to determine whether or not the arcade of Struthers exists through an anatomic dissection study of a fresh human cadaver and seeks to compare its findings with those in the literature.

Mandibular metastases of papillary thyroid carcinoma treated by hemimandibulectomy and costochondral rib graft.

Papillary thyroid carcinoma (PTC) is the most common and well-differentiated cancer of the thyroid. Unlike most cancers, spread to local lymph node does not worsen the survival rate of PTC, and complete resection of the metastases seems to be important and may have favorable effects on the prognosis. A 33-year-old woman was referred to our clinic with a mass involving the right angulus mandible.

Psychiatric disorders and their association with burn-related factors in children with burn injury.

Background: The aim of this study was to assess psychiatric disorders and their association with burn-related factors in a population of Turkish children with burns.

Methods: Thirty-one children admitted to the Cerrahpasa Medical Faculty Burn Unit between January 2013 and August 2013 were first assessed by the plastic surgeon, and then those with psychological symptoms were referred to a child psychiatrist, and the records were analyzed retrospectively.

Results: The percentage of burned area to Total Body Surface Area (TBSA) ranged between 2-60% (mean, 17.

Epidemiology of pediatric burn injuries in Istanbul, Turkey.

Surgical treatment of axillary accessory breasts.

Accessory breast tissue is a remnant persisting after normal embryological development of the breast. Although accessory breasts may be asymptomatic, they can cause discomfort during menstruation, anxiety, cosmetic problems, pain, or restriction of arm movement. The data of all patients who presented with axillary accessory breasts between January 2000 and September 2008 were recruited from a computer database.

Reverse-flow retroauricular island flap in facial reconstruction.

Background: Reconstruction of facial skin defects requires good-quality skin cover to satisfy aesthetic expectations of patient, especially when the skin defect is on the uncovered area of the face. Limitations in the available local tissue and donor-site morbidity restrict the options.

Objective: In an effort to solve these problems, we have begun to use a subcutaneous pedicled retroauricular reverse-flow flap.

The effect of hematoma in muscle flap microcirculation.

Free radicals were first mentioned by Healey about the hematoma under skin flaps, trying to explain the blood itself has different effect beyond its space-occupying effect or infection. The aim of this study was to determine whether hematoma would have any effect on neutrophil behavior in muscle flap microcirculation. Rat cremaster muscle flap model was used for measuring intravital different parameters.

Crossover replantation of the foot after bilateral traumatic lower extremity amputation.

Background: Bilateral traumatic amputation and limb-threatening injury of the lower extremities is more challenging than the unilateral amputation. Successful replantation of both lower extremities has been reported previously. However, orthotopic implantations may not be possible when amputation of both lower limbs with different levels of section and degrees of damage to surrounding tissues occurs.

Does random pattern skin flap supply adequate circulation to the underlying muscle through musculocutaneous perforators by reverse flow? An experimental study.

An experimental study was designed to examine whether the blood supply of the muscle would be maintained by a reverse flow from the random pattern skin flap through the musculocutaneous perforators. A flap model containing rat rectus abdominis muscle and randomly based overlying abdominal skin was designed. Sixty rats were divided into four experimental groups as follows.

Fournier's gangrene: a retrospective clinical study on forty-one patients.

Background: Fournier's gangrene, first described by Dr Jean Alfred Fournier in 1883, still has a high mortality rate. The prognosis and outcome of such patients were analysed.

Methods: Forty-one patients with Fournier's gangrene were reviewed on the parameters of age, sex, aetiological agents, predisposing factors, treatment modalities and outcomes.

Labiocolumellar graft combined with tip graft in the management of inadequate tip projection.

The short distance of the nasal tip from the alar crease indicates inadequate projection. Tip grafts are commonly used for the management of this problem. In addition to tip grafts, labiocolumellar augmentation by cartilage grafts also provides further elevation of the tip complex for patients with poor tip definition, excessive alar base width, inadequate tip projection, or plunging nasal tip.
