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. Total and superficial parotidectomy was used for the treatment of the lesions and none of the patients underwent limited excision. Retrograde approach in 79 (34.4%) patients and anterograde approach in 151 (65.6%) was used. Eighteen patients with malignant tumors were followed up in cooperation with the radiation oncology clinic. Tumors were classified according to their histopathologic diagnosis. Among 192 (83%) benign and 38 (17%) malignant tumors, the most common benign tumor of parotid gland was pleomorphic adenoma (79.1%) while the most common malignant lesion was adenocystic carcinoma (44.7%). Incidences of pleomorphic adenoma, adenocystic and epidermoid carcinoma were greater in male patients. Complication rates in benign and malignant tumors were presented and statistically significant difference could not be found between anterograde and retrograde approach in terms of facial nerve injury (P > 0.05).

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. There were 15 male patients and 13 female patients, with ages ranging between 19 and 74 years. In six of the flaps, venous congestion was observed. Because of the elevation of the eyebrow on the flap side, three patients required a sling to the opposite eyebrow. Excellent color and tissue match and transfer of hair-bearing tissue to the eyebrow and beard areas were achieved with no other complications. Satisfactory aesthetic results were gained.

Sildenafil is a cyclic guanosine-specific phosphodiesterase type 5 (PD-5) inhibitor that is widely used for erectile dysfunction. Potent and competitive inhibition of PD-5 enhances levels of cyclic guanosine monophosphate (cGMP). Fibrin glue-apart from tissue fixation-has been used for slow release of drugs. In this study, local delivery of Sildenafil citrate with fibrin glue was accomplished to improve random flap survival. Fifty Wistar rats were randomized into 5 groups, and a standardized dorsal random-pattern skin flap was elevated in each rat. In Group I (n = 10), the base of the flap was divided, making it a "graft" control to study the graft effect. In Group II (n = 10), a thin Silastic sheet was used to separate the flap from the underlying vascular bed, and no pharmacologic treatment was given. In Group III (n = 10), only 0.5 mL of fibrin glue was applied to the flap donor site. In Group IV (n = 10), 2.5 mg of sildenafil citrate mixed in 0.5 mL of fibrin glue was applied to donor site of the flap, whereas 10 mg of sildenafil citrate mixed in 0.5 mL of fibrin glue was applied in Group V (n = 10). Area of flap survival was evaluated on postoperative seventh day. Total necrosis of all of the flaps was observed in "graft" control group (Group I). Sildenafil and fibrin glue groups (Group IV and V) resulted in a statistically significant decrease in flap necrosis compared with Groups II and III (P < 0.0001). A statistically significant difference could not be documented between Group II and Group III (P > 0.0001). The decrease in skin necrosis was statistically significant in Group V compared with Group IV (P < 0.0001). Histologic examination revealed significantly increased vascular density in Groups IV and V compared with Groups II and III (P < 0.0001), whereas a significant difference could not be documented between Groups IV and V (P > 0.0001) and between Groups II and III (P > 0.0001). In view of these results, topical sildenafil application seems to improve flap survival in random-pattern skin flaps in dose-dependent manner.

Malignant changes arising on the previously traumatized or chronically inflamed skin are defined as Marjolin ulcers. They can develop on many different lesions but frequently they are detected on burn scars. Histopathologically, Marjolin ulcers are mostly diagnosed as squamous cell carcinoma and they need special attention when especially located on the lower extremities. In this study, 63 patients treated for Marjolin ulcers between January 2000 and March 2015 were evaluated according to etiology, histological differentiation, primary tumor size, patient age and anatomical localization. Medical records of these patients were reviewed retrospectively. Mean age was 49.7 years. Average interval between the first injury and carcinoma development was 37.9 years. Most frequent etiologic factor was burn scars with 82.5%. Foot was the most frequently affected site with 28.6% and scalp was the second most frequent localization with 25.4%. Squamous cell carcinomas were detected in 88.9% of the patients and basal cell carcinomas were detected in 11.1% of the patients. For treatment, excision and grafting was performed for 48 patients (76.2%), excision and local flaps were used for 10 patients (15.9%) and excision and free flaps were used for five patients (7.9%). Regional lymph node dissection was performed for 12 patients (19%). Average follow up period was 46.5 months. Local recurrences were detected in nine patients (14.3%). In conclusion, Marjolin ulcers are aggressive tumors that require special care. In order to prevent life threatening sequelas of this entity, it is important to know basic aspects of clinical progress, prognostic factors and treatment modalities.

Reattachment of the amputated fingertips as composite grafts has been performed for distal levels in children, with high rates of good outcome, but the majority of the reports emphasized that this procedure had success rates only up to 50% in adults. Several techniques to enhance composite graft take in adults have been defined. In this study, a technique to enhance nonmicrosurgical replantation of amputated fingertips as composite grafts is presented.Twenty-three patients were treated with this technique, 20 of which were adults. An area of skin on the amputation margin of the stump was deepithelized, and the amputated part was defatted to reattach the piece as a cap composite graft and to increase the contact area. The patients were evaluated after the operations regarding functional and esthetic outcome. Success rates of 86.95% in total and 85% in adults were achieved, with acceptable sensibility (with a mean value of 7.26 mm for the 2-point discrimination), minimal shortening (a mean value of 6.80 mm), and satisfactory esthetic outcome using this technique.

The pull-in technique allows accurate realignment of the tendon-bone unit without any specific instrumentation or intraoperative fluoroscopic imaging methods.

Utilization of bilateral modified V-Y flaps for the closure of large meningomyelocele defects is a simple and effective procedure. Main advantages of the method described in this paper may be listed as follows: simplicity, reliability due to coverage of the defect with well-vascularized flaps, minimal bleeding, decreased operative time, and no donor-site morbidity.

OBJECT Skin grafts, skin flaps, fasciocutaneous flaps, muscle flaps, and musculocutaneous flaps have been used for closure of large meningomyelocele (MMC) defects that cannot be closed primarily. The V-Y rotation advancement flap technique has been used successfully for the reconstruction of defects in different areas of the body. In the present study, the authors report on their novel use of this technique in both a binary and a quadruple (butterfly) flap manner for closure of large MMC defects. They also present an algorithm that they developed for the evaluation of MMC defects. METHODS Between January 2011 and November 2013, 17 patients (13 girls and 4 boys) with extremely large MMC defects that could not be repaired by direct primary closure underwent reconstruction of the defects with binary and quadruple V-Y rotation and advancement flaps. With the patient prone, the axillary apices, the most craniad point of the intergluteal sulcus, and the posterior axillary lines were marked, and a rectangular area on the back was designed. Edges of the rectangular area and the transverse and longitudinal diameters of the defect were measured and the presence of kyphosis was noted. These measurements and their proportions were used to develop an algorithm for patient assessment. While binary flaps were planned over the transverse diameter of the defects, quadruple flaps were planned over the bisectors of the defects, which were closed by elevating fasciocutaneous flaps. RESULTS For patients whose defect diameter to back width ratio was between 0.30 and 0.50 and whose mean ratio of defect area to donor area was between 0.09 and 0.15, binary V-Y rotation and advancement flaps were used. When these values were in the range of 0.50–0.66 and 0.16–0.35, respectively, quadruple V-Y rotation and advancement flaps were preferred. The mean duration of postoperative follow-up was 10.4 months. With the exception of minor complications, such as partial necrosis of 0.5 × 0.5 cm in a quadruple flap, all the flaps healed uneventfully. CONCLUSIONS With this study, closure of MMC defects with V-Y rotation and advancement flaps has been defined for the first time in the literature. The use of this technique with multiple flaps is an effective alternative to other flap options for the closure of large MMC defects. The algorithm developed in the course of this study should facilitate evaluation and reconstruction planning for patients with MMC defects.
