    Objective: In this study, we aimed to evaluate residual tumors and recurrence rates of malignant melanoma (MM) and a nonmelanoma skin cancer of (NMSC) head and neck region. Patients and Methods: Medical data of a total of 398 lesions of 323 patients who underwent surgical excision for a basal cell carcinoma (BCC), squamous cell carcinoma (SCC), and malignant melanoma (MM) were retrospectively analyzed. All patients were classified according to age, sex, location of the tumor, histopathological diagnosis, lesion diameter, excision diameter, surgical margin status, and residual lesions and recurrence rates. Results: There were 244 lesions (61.3%) in 189 males and 154 lesions (38.7%) in 134 females. The most common type of skin cancer was BCC in 268 lesions (67%), followed by SCC in 122 (31%), and MM in eight (2%), respectively. Recurrence was seen in 3% of the NMSC cases and in 25% of the MM cases. There was a statistically significant correlation between the histopathological diagnosis and recurrence rates. Compared to NMSC, MM cases had a higher risk for recurrence (p=0.029). Conclusion: Our study results suggest that recurrence is associated with the localization and type of the tumor, but not with the age or sex of the patient.

    Use of abdominal negative pressure wound therapy in different indications: a case series
    (MA HEALTHCARE LTD, 2019) EROL, BÜLENT; Kocaaslan, Fatma Nihal Durmus; Ozkan, Melekber Cavus; Akdeniz, Zeynep; Sacak, Bulent; Erol, Bulent; Yuksel, Mustafa; Celebiler, Ozhan
    Negative pressure wound therapy (NPWT) is a widely used wound management system. Several articles have been published on the advantages and complications of this system. Abdominal dressing negative pressure system (abdominal NPWT) is a newer technology, developed and used in open abdomen cases. The adherence of the sponge to the intra-abdominal organs is prevented by a polyurethane foam. This study presents a number of case series where an abdominal NPWT (ABThera, KCl, US) has been used to treat other vital organs, helping to prevent complications such as organ rupture and fatal bleeding.

    Implant Stability Outcomes After Immediate and Delayed Revascularized Free Fibula Flaps: A Preliminary Comparative Study
    (QUINTESSENCE PUBLISHING CO INC, 2018) SAÇAK, BÜLENT; Cabbar, Fatih; Kocaaslan, F. Nihal Durmus; Sacak, Bulent; Capar, Gonca Duygu; Celebiler, Ozhan
    Purpose: This pilot study investigated the retrospective outcomes of implants placed immediately or with a delayed protocol in revascularized free fibula flaps (FFF). Materials and Methods: Patients undergoing FFF between 2014 and 2017 were included in the study. Implants were inserted either immediately or 23.63 +/- 10.61 months after reconstructive surgery. Resonance frequency analyses were recorded at the time of implant placement (first control) and 4 months postoperatively while uncovering and screwing the gingiva formers (second control). The statistical significance level was set at P < .05. Results: Eight patients (four men, four women, mean age: 46.75 +/- 12.96 years) were included in the study. Twenty-six implants were placed in FFF (14 immediate, 12 delayed), and 28 were placed in the alveolus. All implant stability quotient (ISQ) scores were in high stability ranges. Statistically significant differences were observed between delayed (79.25 +/- 4.77) and immediate implant placement (73.14 +/- 7.42) at first controls, but not at second controls (79.17 +/- 3.59 and 76.00 +/- 6.18). The ISQ values of immediate implant placement significantly increased from first to second controls (P = .018). Bicortically placed implants showed significantly higher scores than unicortical implants (P < .05). ISQ values of FFF and alveolar bone groups were similar (P > .05). Conclusion: High stability scores similar to alveolar bone could be achieved by both immediate and delayed implant placement. Bicortical implantation results in better implant stability.
