Anthropometric Breast Measurement: A Study of 385 Turkish Female Students

BACKGROUND Anthropometric measurements and proportions of the human body have made a significant contribution to the science of aesthetic and reconstructive plastic surgery. OBJECTIVE The present study was performed to measure anthropometric breast values in Turkish female students and compare them with those of women in other nations. METHODS The study included 385 female undergraduate student volunteers between the ages of 18 and 26 years with no physical or developmental deformity and with a body mass index between 20 and 26. A total of 19 parameters were measured in a standing position. The parameters measured were body weight, height, shoulder width, upper chest width, middle chest width, lower chest width, waist width, hip width, clavicle-nipple length, sternal notch-nipple length, nipple-nipple length, upper arm length, medial mammary radius, lateral mammary radius, nipple-inframammary fold length, nipple diameter, areola diameter, nipple projection, and mammary projection. Breast volume, breast ptosis, and retracted nipple rates were also assessed. RESULTS The mean breast volume was determined to be 407.2 +/- 263.6 cc. The mean values of the right and left breast volumes were calculated as 415.2 +/- 264.5 cc and 399.1 +/- 265.5 cc, respectively; the right breast volume was significantly greater than the left breast volume (P < .001). The ideal external view of the breasts with equal volume for both sides and no ptosis was observed in 35.1% of the volunteers. The percentage of women with unilateral or bilateral retracted nipple was 2.6%. CONCLUSIONS The results of the present study will help in comparing the anthropometric breast values of young Turkish women with those of women in other countries. They may also be useful either in planning aesthetic and reconstructive breast surgery or in designing breast augmentation accessories and clothing.

The Fate of Intramuscularly Injected Fat Autografts: An Experimental Study in Rabbits

An experimental study was designed to assess the viability and revascularization of intramuscularly injected fat autografts. For the study, 18 rabbits were divided into two groups. In the first group, fat was injected intramuscularly (12 rabbits). Autologous fat was obtained from the inguinal area and subsequently injected into the thigh muscle. In the second group, physiologic saline was injected intramuscularly to determine the effects of cannulation and pressure on muscle tissue (6 rabbits). Fat autografts were performed on the right side of the animal, and the left side was used as the control. Scintigraphic imaging and histopathologic examination of the limbs were performed after injection of adipose tissue on days 15, 30, 45, 60, 90, and 120. On the technetium-99m (99mTc) hexamethylpropylene amine oxime scintigraphy, whereas similar activity distribution was observed between the left and right thigh on days 15, 30, and 45, there was increased uptake at the right thigh on days 60, 90, and 120. This increased uptake indicates that there is viable fat tissue in this region. Histopathologic evaluation showed that microcysts resulting from degeneration of some adipocytes and inflammatory changes on day 15 additionally increased vascularity and fibrosis in some animals on day 30, as well as fibrosis, microcysties, and focal calcification areas in adipose tissue on day 45 and later. It was observed that adipose tissue survived in more than 50% of the graft area in all the animals. These findings show that fat autografts can survive in muscle tissue with less than 50% fibrotic change.

Review of monitoring free muscle flap transfers in reconstructive surgery : role of 99mTc sestamibi scintigraphy

BackgroundFree tissue transfer is a method of moving any tissue from a donor area of the body to a recipient site and re-attaching the arteries and veins to the blood vessels at the recipient site by microvascular surgery. Improved microsurgical techniques have resulted in a high percentage of successful free tissue transfers. Post-operative monitoring of tissue viability can detect early problems in free tissue transfer which may allow early intervention and salvage. Although many flap monitoring methods have been described, there is still no consensus on which of these techniques will become the standard accepted method for monitoring free muscle flaps. ObjectiveIn present study, we investigated the use of 99mTc sestamibi scintigraphy in determining free muscle flap viability and complications, and also in directing treatment. MethodsThirteen patients were examined prospectively during the post-operative period after free tissue transfer for foot defects. The cause of the defect was diabetic foot ulcer in 10 patients, dermatofibrosarcoma in one patient, squamous cell carcinoma in one patient and gunshot wound in one patient. Foot defect covering was carried out with a free latissimus dorsi muscle flap and skin graft (n=12) and a free gracilis muscle flap (n=1). All patients were examined with a monitoring system that consisted of visual inspection, hand-held Doppler ultrasonography and scintigraphic examinations. Scintigraphic imaging of all cases was performed routinely within the first 48 h post-operatively, and also on days 10 and 91 in two patients. ResultsThere were four flap failures during the study. One of these patients had viable findings upon visual inspection and no evidence of vascular compromise on Doppler at the first examination. In the other patient, visual inspection of the flap showed that it was ischaemic in one region, but there was no vascular compromise on Doppler examination. Scintigraphic images of each of these patients showed a partial hypoperfused area in the flap region. Later, these two flaps showed positive clinical indications of hypoperfusion (colour of muscle and appearance of skin graft) and Doppler abnormalities. The remaining two patients had non-viable scintigraphic images as well as positive clinical indicators of hypoperfusion and evidence of vascular compromise on Doppler. Nine patients each had a viable flap. In these patients, all three examination tools demonstrated that the flaps were totally viable and there were no vascular complications. ConclusionAccording to the results of this study, 99mTc sestamibi scintigraphy appears to be a feasible and promising method in the evaluation of free muscle flap viability and complications. On the other hand, to demonstrate any impact on management or patient outcome, further evaluation of 99mTc sestamibi imaging, including comparative studies with different established methods in a larger patient population, is highly recommended.

A Case of Self-inflicted Intraorbital Injury: Wooden Foreign Body Introduced into the Ethmoidal Sinus

A patient with an intraorbital wooden foreign body is presented. A 43-year-old schizophrenic male patient purposely introduced a twig through his left medial canthus and into the orbital cavity 6 months before presentation. Magnetic resonance imaging showed a well-delineated intraorbital object that partially penetrated the ethmoidal sinus through the medial orbital wall. Under general anesthesia, a 55-mm-long and 6-mm-diameter twig was removed through an incision along the sulcus palpebromalaris. Thick capsule formation around the foreign body, fibrosis of the adjacent tissues, and severe infection were observed. Diagnosis and management of intraorbital foreign bodies are discussed.

Distally based sural flap in treatment of chronic venous ulcers.

The treatment of venous ulcers of the leg often fails to heal because venous ulcers are mostly associated with severe lipodermatosclerosis. These complicated ulcers may require correction of local hemodynamics, excision of ulcer with surrounding lipodermatosclerotic skin, and replacement of the defect with healthy tissue. We present our experience with the use of the distally based sural flaps for the reconstruction of soft-tissue defects of the distal region of the lower limb in patients with chronic venous ulcer. Between 2001 and 2003, 12 patients with venous ulceration were treated with distally based sural flaps. At operation, the ulcer and its surrounding lipodermatosclerotic skin were excised. The defects after excision ranged from 3 × 3 to 11 × 17 cm. The distally based sural artery flap was inset within the defect. In all patients, the flap survived completely, and in only 1 patient, distal venous congestion was seen and was treated successfully with leeches. There was donor site skin graft loss in 2 patients. Two flaps had minor local complications that healed with local wound care. No recurrent ulcers were identified after average 19.7 months. In conclusion, the distally based sural flaps can be used reliably for treatment of venous ulcers. Our approach in treatment of chronic venous ulcers improves venous hemodynamics and provides local flap alternative that should be considered prior to a free-flap transfer for closure of the defect.

Intraorbital wooden foreign body: clinical analysis of 32 cases, a 10-year experience

BACKGROUND We aimed to describe herein the clinical features, diagnosis and treatment of intraorbital wooden foreign body injuries. METHODS A case series review of orbital injuries managed at Trakya University Faculty of Medicine between 2002 and 2012 was performed retrospectively. The clinical analysis of 32 intraorbital wooden foreign body injuries was reviewed. RESULTS Among the 32 cases, injuries in 16 were caused by a tree branch, in 10 by a pencil, in 5 by a stick, and in 1 by a bush. With respect to preoperative vision, postoperative vision was improved in 69% of patients. Time lapse from injury to presentation was correlated with the size of the foreign body. The subjects were comparable in etiological factor, and distribution of injury according to orbit was as follows: superior 28%, medial 25%, lateral 22%, inferior 16%, and posterior 9%. Computerized tomography (CT) for foreign body was definitive in 72% (n=23) and suggestive in 28% (n=9). CONCLUSION The diagnosis of orbital wooden foreign body is difficult because it may be missed clinically and from the imaging perspective. If a foreign body is suspected, optimal patient management should be done. Prior to the surgery, imaging modalities should be maximally utilized. A careful preoperative evaluation, imaging studies, which are event-specific, a high index of suspicion, and rigorous surgery and postoperative care are the keys in the management of orbital wooden foreign body injuries.

Management of the Long Nose: Review of Techniques for Nasal Tip Supporting Structures

The long nose with a “plunging” tip is a deformity that involves an inferiorly rotated nasal tip, leading to an increase in the length of the nose. The anatomic basis of the long nose with a plunging tip may be divided into two types. Type 1 presents a normal alar–cartilage complex inferiorly displaced by a long nasal septum and long upper lateral cartilages. Type 2 is caused by a dislocation of the alar cartilages downward from the aponeurotic attachments to the septal angle. During the study period, the authors identified 60 patients with long noses and plunging tips. For 22 patients with type 1 long noses, the high septal incision technique was used in 12 cases and the step technique in 10 cases. The invagination procedure alone was used for 22 of 38 patients with type 2 plunging noses. Also, an extension graft with the invagination procedure was used for 6 patients, and a columellar strut graft was used for 10 patients. A high septal incision increased tip rotation without significantly changing the amount of tip projection. However, the step procedure, the invagination technique alone, septal extension graft with the invagination technique, and columellar strut grafts increased nasal tip rotation and projection. During the study period, 38 patients were identified as having a smiling deformity, which was improved using the authors’ modification procedure. On the basis of the results, the authors recommend that the appropriate treatment for each patient with a long nose and a plunging tip must be determined by preoperative and intraoperative examination findings with the patient at rest and while smiling.

A New Approach to Smiling Deformity: Cutting of the Superior Part of the Orbicularis Oris

A diagnosis of an aesthetic smiling deformity, which is functional rather than anatomic, is essential for provision of the best treatment in rhinoplasty. Smiling deformity consists of three elements: (a) the nasal tip tending to retrodisplace and rotate inferiorly; (b) the lower part of the upper lip moving superiorly; and (c) a horizontal groove occurring in the midphiltral area. An active depressor septi and orbicularis muscle can accentuate a drooping nasal tip and shorten the upper lip during smiling. Downward movement of the nasal tip and a sharper nasolabial angle usually are aesthetically unpleasant. During the study period (January 2000 to January 2004), the authors identified 38 patients with smiling deformities, 16 of whom underwent dissection and transposition of the paired depressor septi during rhinoplasty. The remaining 22 patients experienced hyperactivity of both the depressor septi and orbicularis muscles, as diagnosed by a descending nasal tip and a shortened upper lip at animation. These patients underwent a modification of the depressor septi and orbicularis muscles. No relapse was evident up to 2 years postoperatively. Repositioning of the depressor septi nasi muscle improved only mild cases. However, modification of the orbicularis and depressor septi muscles was a valuable adjunct to rhinoplasty for moderate and severe forms of smiling deformity. The new approach for smiling deformity provided an aesthetically pleasant appearance for the patient both at rest and when smiling.

Bone flap prefabrication: an experimental study in rabbits.

The usual method to prefabricate a bone flap is to harvest a nonvascularized bone graft and to implant the artery and vein bundle between segments of bone graft. The basic problem of this method is sacrificing an artery for prefabrication. Another method for creating flap donor sites without using an artery is venous flap prefabrication. There are a few articles describing bone flap prefabrication, and these include implantation of both artery and vein as a vascular bundle. Also, there is no experimental study in the literature using a vein or an arterialized vein pedicle for bone flap prefabrication. As an experimental model for bone flap prefabrication, the rabbit ear vascular model was chosen. For the experiments 3 groups were formed. Each group contained 5 rabbits. In the first experimental group a vein was implanted between the halves of bone graft. In the second experimental group an arterialized vein was implanted between the halves of bone graft. To compare the viability of the bone graft of the 2 prefabrication groups, a bone graft was implanted into the subcutaneous pocket of the posterior auricular area in the third group. The authors examined 5 rabbits in each group by microangiography at the end of 6 weeks except for group 3. On microangiographic analysis, groups 1 and 2 showed patency of the vascular pedicle. There was no difference between these 2 groups from the point of view of vascular patency and bone appearance. Bone scintigraphy was performed for 5 rabbits in each group. On bone scintigraphic scans, the bone component of the flaps was visualized in groups 1 and 2, but not in group 3. A quantitative analysis of images was performed by drawing symmetric spherical regions of interest (ROIs) over both the implanted area and cranial bone. The uptake ratios were computed by dividing the mean counts in the implanted ROI by mean counts in the cranial bone ROI. The mean value was 0.86 ± 0.02 in group 1 and 0.86 ± 0.04 in group 2. A statistically significant uptake difference was not seen between venous and arterialized venous groups (P < 0.01). Histologic examination was performed all rabbits in each group, and demonstrated that the bony component was viable, showing osteocytes containing lacunae, osteoblasts along bony trabeculae, and vascular channels in groups 1 and 2. In group 3, the bony architecture of the graft was still apparent, but all bone within it was dead. There were no significant microangiographic, histologic, and scintigraphic differences between the 2 experimental methods.

Posttraumatic intramuscular hemangioma of the left temporal muscle

Intramuscular hemangioma involving the skeletal musculature is an uncommon tumor. These benign vascular lesions account for less than 1% of all hemangiomas. In the head and neck region, intramuscular hemangioma occurs most commonly in the masseter and trapezius muscle. The cause of these unusual lesions remains unknown, although trauma and abnormal sequestration of embryonic tissue have been postulated. Today, trauma is considered a factor in causing proliferation of pre-existing embryonic vascular malformations. Intramuscular hemangioma of the temporal muscle is rare in presentation, with few reports in the English literature. Herein, we present a case of posttraumatic intramuscular hemangioma of left temporal muscle after blunt trauma to temporal region.
