Extensive Convexity Flattening of a Synthetic Skull Implant the Overcome Major Scalp Deficiency After Multiple Craniotomies.

ABSTRACT: Multiple craniofacial surgeries and postoperative recalcitrant infections frequently can lead to secondary scalp tissue scarring and skin retraction. Although there are different methods of reducing and optimizing scalp skin tension, the authors describe a last resort treatment method of cranioplastic procedure, which despite of its unfavorable cosmetic outcome, relieves the skin tension through extensive flattening of the polyetheretherketone curvature. Thereby, a custom-made cranioplastic bone flap was extensively flattened in the curvature of the fronto-parietal area with consideration of the related brain hemisphere extension. The extent of bone curvature flatting reduced the skin tension significantly and allowed for plain and simple tension-free wound closure in a chronic smoker patient with poor skin quality and brain atrophy. Although brain extension was sufficient, the cosmetic outcome was unfavorable with regard to skull symmetry, but well accepted and satisfactory for the patient due to preoperative discussion outcome expectation from surgery. Thus, extensive polyetheretherketone curvature flattening is a straightforward and simple last resort treatment option for tension-free skin closure in high-risk patients with extensive skin scarring and retraction and previous reconstructive plastic skin relief procedures. However, this method is limited in patients with normal brain hemisphere extension.

Burr-Hole Drainage for Chronic Subdural Hematoma Under Low-Dose Acetylsalicylic Acid: A Comparative Risk Analysis Study.

BACKGROUND: Chronic subdural hematoma (cSDH) is one of the most common neurosurgical diseases typically affecting older people. Many of these patients have coronary artery disease and receive antiplatelet therapy, usually acetylsalicylic acid (ASA). Despite growing clinical relevance, there is still a lack of data focusing on the perioperative management of such patients. OBJECTIVE: The aim of this study is to compare the perioperative and postoperative bleeding and cardiovascular complication rates of patients undergoing burr-hole drainage for cSDH with and without discontinuation of low-dose ASA. METHODS: Of 963 consecutive patients undergoing burr-hole drainage for cSDH, 198 (20.5%) patients were receiving low-dose ASA treatment. In 26 patients (13.1%), ASA was not discontinued (ASA group; ASA discontinuation ≤7 days); in the remaining patients (n = 172; 86.9%), ASA was discontinued at least for 7 days (control group). The primary outcome measure was recurrent cSDH that required revision surgery owing to clinical symptoms, whereas secondary outcome measures were postoperative cardiovascular and thromboembolic events, other complications, operation and hospitalization time, morbidity, and mortality. RESULTS: No statistically significant difference was observed between the 2 groups regarding recurrence of cSDH (P = 1). Cardiovascular event rates, surgical morbidity, and mortality did not significantly differ between patients with and without discontinuation of low-dose ASA. CONCLUSION: Given the lack of guidelines regarding perioperative management with antiplatelet therapy, our findings elucidate one issue, showing comparable recurrence rates with and without discontinuation of low-dose ASA in patients undergoing burr-hole drainage for cSDH.
