[source] Nasalis Island Pedicle Flap in Nasal Ala ReconstructionDERMATOLOGIC SURGERY, Issue 4 2005Maryam Asgari MD Background. Defects of the nasal ala can be difficult to repair in a one-stage procedure. We describe a laterally based nasalis myocutaneous island pedicle flap to repair small but deep defects of the superior nasal ala. Objective. To describe a single-stage flap for repair of small defects on the nasal ala that confines the repair to one cosmetic unit. Methods. We discuss the anatomy of the flap and illustrate the method of placing the flap. Results. We present several case examples and discuss potential applications of the flap. We also discuss the flap's limitations by citing an example of necrosis. Conclusions. The nasalis myocutaneous island pedicle flap for repair of nasal alar defects is a new application of a one-stage procedure that yields excellent functional and cosmetic results. Knowledge of the limitations and the anatomy of the flap is crucial for a good outcome.

[source] Single-stage Matriderm® and skin grafting as an alternative reconstruction in high-voltage injuriesINTERNATIONAL WOUND JOURNAL, Issue 5 2010Henning Ryssel This article presents a retrospective analysis of a series of nine patients requiring reconstruction of exposed bone, tendons or joint capsules as a result of acute high-voltage injuries in a single burn centre. As an alternative to free tissue transfer, the dermal substitute Matriderm® was used in a one-stage procedure in combination with split-thickness skin grafts (STSG) for reconstruction. Nine patients, in the period between 2005 and 2009 with extensive high-voltage injuries to one or more extremities which required coverage of exposed functional structures as bone, tendons or joint capsule, were included. A total of 11 skin graftings and 2 local flaps were performed. Data including regrafting rate, complications, hospital stays, length of rehabilitation and time until return to work were collected. Eleven STSG in combination with Matriderm® were performed on nine patients (success rate 89%). One patient died. One patient needed a free-flap coverage as a secondary procedure. The median follow-up was 30 months (range 6,48 months). The clinical results of these nine treated patients concerning skin-quality and coverage of exposed tendons or joint capsule were very good. In high-voltage injuries free-flap failure occurs between 10% and 30% if performed within the first 4,6 weeks after trauma. The use of single-stage Matriderm® and skin grafting for immediate coverage described in this article is a reliable alternative to selected cases within this period. [source] Non-surgical periodontal treatment with a new ultrasonic device (VectorÔ-ultrasonic system) or hand instrumentsJOURNAL OF CLINICAL PERIODONTOLOGY, Issue 6 2004A prospective, controlled clinical study Abstract Objectives: The aim of this prospective, randomized, controlled clinical study was to compare the effectiveness of a newly developed ultrasonic device to that of scaling and root planing for non-surgical periodontal treatment. Material and Methods: Thirty-eight patients with moderate to advanced chronic periodontal disease were treated according to an "one-stage procedure" with either a newly developed ultrasonic device (VUS) (VectorÔ-ultrasonic system) or scaling and root planing (SRP) using hand instruments. Clinical assessments by plaque index (PlI), gingival index (GI), bleeding on probing (BOP), probing depth (PD), gingival recession (GR), and clinical attachment level (CAL) were made prior to and at 6 months after treatment. Differences in clinical parameters were analyzed using the Wilcoxon signed ranks test and Mann and Whitney U -test. Results: No differences in any of the investigated parameters were observed at baseline between the two groups. The mean value of BOP decreased in the VUS group from 32% at baseline to 20% after 6 months (p<0.001) and in the SRP group from 30% at baseline to 18% after 6 months (p<0.001). The results have shown that at moderately deep sites (initial PD 4,5 mm) mean CAL changed in the test group from 4.6±1.2 to 4.2±1.6 mm (p< 0.001) and in the control group from 4.8±1.3 to 4.4±1.5 mm (p<0.001). At deep sites (inital PD>6 mm) mean CAL changed in the test group from 8.5±1.9 to 7.9±2.4 mm (p<0.001) and in the control group from 7.9±1.6 to 7.2±2.2 mm (p<0.001). No statistically significant differences in any of the investigated parameters were found between the two groups. Conclusion: Non-surgical periodontal therapy with the tested ultrasonic device may lead to clinical improvements comparable to those obtained with conventional hand instruments. [source] Role of resection and primary anastomosis of the left colon in the presence of peritonitis,BRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 11 2000Dr S. Biondo Background Classically a primary colonic anastomosis is not performed in the presence of left colonic peritonitis. Recently there has been a trend towards resection and anastomosis in selected patients, but no prospective study concerning the safety of this approach has been published. The objective of this study was to define the role of intraoperative colonic lavage with resection and primary anastomosis (RPA) in left colonic peritonitis, and to evaluate the differences in outcome in patients with diffuse or localized peritonitis. Methods Between January 1994 and December 1998, 127 patients underwent emergency operation for a distal large bowel perforation. RPA was the operation of choice and was performed in 61 patients, 38 with localized and 23 with diffuse peritonitis. Septic shock, faecal peritonitis, immunocompromised status and American society of Anesthesiologists grade IV were contraindications to the one-stage procedure. Alternative operations used in high-risk patients were Hartmann's procedure in 55 patients, subtotal colectomy in eight and colostomy in three. Results There were two deaths (3 per cent) among 61 patients treated by RPA and one (2 per cent) case of clinical anastomotic dehiscence. Overall morbidity was 39 per cent and the overall mean(s.d.) hospital stay was 18(15) days. No statistical differences were observed between patients with localized and diffuse peritonitis treated by RPA. Conclusion RPA may be the operation of choice in selected patients with left colonic diffuse peritonitis. © 2000 British Journal of Surgery Society Ltd [source] A comparison of one-stage procedures for post-traumatic urethral stricture repairBJU INTERNATIONAL, Issue 9 2005Andreas P. Berger OBJECTIVE To compare the results and complication rates of various one-stage treatments for repairing a post-traumatic urethral stricture. PATIENTS AND METHODS The medical records of 153 patients who had a post-traumatic urethral stricture repaired between 1977 and 2003 were evaluated retrospectively, and analysed for the different types of urethral reconstruction. RESULTS The procedures included direct end-to-end anastomosis in 86 (56%) patients, free dorsal onlay graft urethroplasty using preputial or inguinal skin in 40 (26%), ventral onlay urethroplasty using buccal mucosa in seven (5%) and ventral fasciocutaneous flaps on a vascular pedicle in 20 (13%). At a mean (median, range) follow-up of 75.2 (38, 12,322) months, 121 (79%) patients had no evidence of recurrent stricture, while in 32 men (21%) they were detected at a mean follow-up of 30.47 (1,96) months. Patients having a dorsal onlay urethroplasty had the longest strictures. The re-stricture rate was lowest after a dorsal onlay urethroplasty (5% vs 27% when treated with end-to-end anastomosis, 15% after fasciocutaneous flaps and 57% after a ventral buccal mucosal graft). The surgical technique used had no effect on postoperative incontinence or erectile dysfunction rates. CONCLUSION In patients with strictures which are too long to be excised and re-anastomosed, tension-free dorsal onlay urethroplasty is better than ventral graft or flap techniques. In patients with short urethral strictures direct end-to-end anastomosis remains an option for the one-stage repair of urethral stricture. [source] | ||||||||||
