Evaluation of keyhole-pattern reduction glossoplasty for macroglossia in beckwith-wiedemann syndrome: A multidimensional analysis of postoperative course and outcomes

The aim of this study was to evaluate the postoperative course and long-term functional and aesthetic outcomes in patients with Beckwith-Wiedemann syndrome (BWS) following surgical reduction of macroglossia, using multiple questionnaires. Patients with BWS who underwent keyhole reduction for macroglossia were included in this study. The postoperative course for each patient was recorded, and multiple questionnaires were administered to evaluate aesthetic concerns, oral incompetence or feeding difficulties, sleep-disordered breathing symptoms, and speech. Nine patients underwent ten reduction glossoplasty surgeries. The mean age at surgery was 22 months. The postoperative course for each case was uneventful, except for one patient who had wound dehiscence. The questionnaires revealed significant improvements in tongue appearance, feeding, drooling, facial appearance, and psychosocial outcomes. There was also a significant reduction in sleep-disordered breathing symptoms after surgery. Keyhole reduction glossoplasty is a safe and effective procedure for the treatment of macroglossia in BWS patients, with excellent functional and aesthetic outcomes and a low complication rate.

Flap loss in head and neck reconstruction: Is there a singular cause for failure?

Despite the high success rates reported in head and neck reconstruction, free flap failures continue to persist. Understanding the factors associated with flap loss and improving overall success are paramount. This study aimed to comprehensively assess the factors influencing flap revision and free tissue transfer survival in head and neck reconstruction. The study included 70 patients with defects in the lower two-thirds of the head and neck region and underwent reconstruction using free flaps. Patient age, gender, smoking status, comorbidities and data on the location and aetiology of the defect, the specific type of flap employed, the recipient artery and vein chosen, instances of revision and the overall success of the flap were collected. The investigation aimed to establish correlations between these variables as well as flap success and revision rates. No statistically significant differences were observed in arterial and venous anastomosis revision rates, or flap survival, in relation to variables such as age, gender, flap type, smoking status, comorbidities, recipient artery or vein and the number of vein anastomoses. The malignant tumour group exhibited a lower requirement for arterial revision and a higher flap survival rate compared to the benign tumour group. This study underscores the comparable safety profiles of perforator-based and conventional flaps in head and neck reconstruction. Furthermore, it reveals that patient characteristics are not contraindications for free tissue transfer. Additionally, the quantity of the veins and choice of recipient vessels are flexible and do not significantly impact flap success. The higher rates of flap success in patients with malignant aetiology requires further investigation.

Robotic harvest of the free gracilis muscle flap

The conventional approach to harvest of the gracilis muscle flap necessitates a medial thigh incision that is often related to several donor site complications. In this report we describe the robotic harvest of the free gracilis muscle flap in order to reduce the morbidity associated with the open incision. Through three ports, the robotic system (Da Vinci Xi, Intuitive Surgical) enables precise dissection of the gracilis muscle, the vascular pedicle, and the obturator nerve; thus, enhancing surgical control, optimizing visualization through magnification, aiding in detailed vascular pedicle dissection and minimizing human error. We believe that the technique of totally robotic harvest of the free gracilis muscle flap, herein introduced, is a feasible and effective approach, and confers specific advantages over traditional harvest technique.

The effect of time from injury to fasciotomy in patients with acute upper extremity compartment syndrome

BACKGROUND

Acute compartment syndrome of the upper extremity is a surgical emergency, and timely diagnosis with immediate fasciotomies is essential for the preservation of function. This retrospective study aimed to compare the complication rates of patients who underwent fasciotomy before and after 6 hours following the initial trauma.

METHODS

The medical records of the patients who underwent fasciotomy for surgical treatment of ACS of the upper extremity between 2016 and 2022 were retrospectively analyzed for age, gender, dominant hand, mechanism of injury, injury level, affected compartments, associated injuries, time elapsed till fasciotomy, and complications. The patients were divided into two groups according to the timing of fasciotomy.

RESULTS

A total of 32 patients underwent fasciotomies for upper extremity ACS. The mean age of patients who underwent fasciotomy ≤ 6 hours (group 1; 10 males, 7 females) and patients who underwent fasciotomy > 6 hours (group 2; 13 males, 2 females) was 31.1 and 34.8, respectively. The most common etiology was crushing injury. There was a significant difference in complication rates between group 1 (1/17) and group 2 (10/15) (p<0.001). The length of hospitalization stay in group 2 was statistically higher than in group 1 (p=0.005).

CONCLUSION

Fasciotomies for ACS of the upper extremity should be performed in less than 6 hours following the initial trauma to prevent complications.

Safe, fast, and minimally-assisted microsurgical anastomosis with combined open-loop suturing and airborne tying: a clinical and experimental study

BACKGROUND

The continuous open-loop technique accelerates anastomosis and eliminates the risk of inadvertently catching the back wall, which is the primary cause of technical failure when using interrupted sutures in microsurgical anastomosis. Combined with airborne suture tying, the total anastomosis time is significantly reduced. We conducted an experimental and clinical study to compare this combination to the conventional technique.

METHODS

Experimentally, anastomoses were performed on the femoral arteries (0.60 mm) of rats in two groups. The control group used simple interrupted suturing with conventional tying, while the experimental group employed open-loop suturing with air-borne tying. We recorded the total time taken for anastomosis completion and patency rates. Clinically, we retrospectively analyzed replantation and free flap transfer cases using the open-loop suture and airborne tying technique for arterial and venous microvascular anastomoses, assessing total anastomosis time and patency rates.

RESULTS

Experimentally, a total of 40 anastomoses were performed in two groups. The control group required 779.65 seconds, and the experimental group needed 527.4 seconds for anastomosis completion; this difference was statistically significant (p<0.001). Immediate and long-term patency rates were similar (p=0.5483). Clinically, 18 replantations were performed on 16 patients, and 17 free flap transfers were performed on 15 patients, totaling 104 anastomoses. The anastomosis success rate was 94.2% (33 of 35) for free flap transfers and 95.1% (39 of 41) for replantation cases.

CONCLUSION

The open-loop suture technique with airborne knot tying allows surgeons to complete microvascular anastomoses safely and in less time with minimal assistance when compared to the simple interrupted suture technique.

Utilization of reverse osmosis (RO) for reuse of MBR-treated wastewater in irrigation-preliminary tests and quality analysis of product water

Membrane bioreactor (MBR) effluent collected from a wastewater treatment plant installed at an industrial zone was used for reverse osmosis (RO) membrane tests in the laboratory. For this, two different GE Osmonics RO membranes (AK-BWRO and AD-SWRO) were employed. The results showed that AK-brackish water reverse osmosis (AK-BWRO) and AD-seawater reverse osmosis (AD-SWRO) membranes have almost similar rejection performances regarding analyzed parameters such as conductivity, salinity, color, chemical oxygen demand (COD), and total organic carbon (TOC). On the other hand, these membranes behaved quite differently considering their permeate water flux at the same applied pressure of 10 bar. AD-SWRO membrane was also tested at 20 bar. The results revealed that AD-SWRO membrane had almost the same rejections either at 10 or at 20 bar of applied pressure. Compared with irrigation water standards, AK-BWRO and AD-SWRO gave an effluent with low salinity value and sodium adsorption ratio (SAR) which makes it unsuitable for irrigation due to the infiltration problems risi0ng from unbalanced values of salinity and SAR. Combination of MBR effluent and RO effluent at respective proportions of 0.3:0.7 and 0.4:0.6 for AK-BWRO and AD-SWRO, respectively, are the optimum mixing ratios to overcome the infiltration hazard problem. Choice of less-sensitive crops to chloride and sodium ions is another strategy to overcome all hazards which may arise from above suggested mixing proportions.

When organ donation from living donors serves as the main source of organ procurement: a critical examination of the ethical and legal challenges to Turkey's recent efforts to overcome organ shortage

Despite the fact that Turkey has implemented a number of legislative and regulatory efforts to increase cadaveric donations, live donors still serve as the main source of organ procurement in this country. To address this problem, Turkey's regulatory authorities have sought to increase the number of brain death declarations. A new regulation issued in 2012 repeats the criteria for brain death that were first issued in 1993. This paper argues that these efforts are far from adequate owing to a number of complicated, ethical, and legal challenges that must be addressed to increase cadaveric organ donations. After examining these factors, which are completely neglected in current policies, we conclude that Turkey needs a realistic ethically justifiable organ procurement policy that must be supported by a framework of patient rights to implement the concept of patient autonomy and respect for human dignity in health care services as the primary goal.
