Objective To investigate the application of transverse fascia in inguinal hernia repair. Methods In this study, 617 patients underwent inguinal hernia repair between January 1990 and December 2005 in our hospital were included, which were divided into two groups according to different operative ways: transverse fascia method group (n=337) and Bassini method group (n=280). Then intraoperative results, postoperative complications, and rehabilitated results of patients in two groups were compared. Results Compared with Bassini method group, the patients in transverse fascia method group did not show significant difference in operative time and blood loss during operation (Pgt;0.05). The differences of severe postoperative pain, testicular swelling, the time of the body’s restore for normal activities, and recurrence rate of patients between two groups were significant (Plt;0.05), while the difference of hematoma of scrotum and infection of incisional wound (Pgt;0.05). Conclusion The strengthening of posterior wall by transverse fascia and reconstruction of inner ring is a simple and effective method for inguinal hernia repair.
The noses of eight patients being dead for 2hours were dissected to investigate the layers andstructure of the nose, and the stability of theimplanted silicone noae prosthesis was tested.According to the structure and microstructure ofthe nose studied by us, we suggested a newconcept of nasal muscle and dorsal deepfasciacomplex. We confirmed the prcathesis should beimplanted in the space between the nasal boneand the complex. The reason for complicationhappened in this approach was that...
Considering the abundant vascular anastomotic networks in the deep fascia of the posterior calf, three kinds of distally based facial flap containing deep fascial vascular network were applied clinically. They were: 1. posterolateral distally based island fascial flap which could be used to repair the skin defect of heel, dorsum of foot and lateral-distal part of leg; 2. posteromedial distally based island fascial flap which could be used to repair the skin defect of heel, medial malleolus and medial-distal part of leg and 3. posterolateral malleolar distally based fascial flap which could be used to repair the skin defect of heel and lateral malleolus. Eighteen cases with soft tissue defects around the distal calf were treated, the area of skin defect ranged from 4 cm x 3 cm to 13 cm x 6 cm. All the flaps were survived completely after operation with an average of follow-up for 15 months (ranged from 6 months to 2 years). So the advantages of these flaps were as follows: the blood supply was reliable, preparation of the flap was easy and the major arteries of the calf needed not be sacrificed; the flap had a long and rotatable pedicle so that they would basically satisfy the need to repair skin defect of lower leg, dorsum of foot, heel and malleolus and the resistance of the flap to pressure and wear was better. However, the injury to the superficial sural nerve was the shortcoming.
Objective To evaluate the reliability and effectiveness of a deep circumflex iliac artery based iliac-internal oblique musculofascial chimeric flap (DCIA-IIOF) in reconstruction of complex oromandibular defect. Methods Between January 2010 and December 2015, DCIA-IIOFs were used to repair complex oromandibular defects in 11 patients. There were 8 males and 3 females, with an age of 27-75 years (median, 56 years). Original disease was lower gingival squamous cell carcinoma in 7 cases (T3N1M0 in 2 cases, T3N2M0 in 1 case, T4N0M0 in 2 cases, and T4N2M0 in 2 cases), osteoradionecrosis after radiotherapy for nasopharyngeal carcinoma in 2 cases, central mandibular squamous cell carcinoma in 1 case (T4N0M0), and mandibular malignant fibrous histiocytoma in 1 case. The length of mandibular bone defects ranged from 7 to 10 cm (mean, 8 cm), and the area of the mucosal defects ranged from 5 cm×3 cm to 7 cm×4 cm. Preoperative ultrasonic identification of the DCIA and its ascending branch was routinely performed. The DCIA-IIOF was harvested by using an anterograde dissection technique, of which the iliac island was used for segmental mandibular defect repair and the musculofascial island for soft tissue and mucosal defect repair. Results All 11 cases were followed up 15-75 months (median, 37 months). All flaps survived after operation, without necrosis of both iliac island and oblique internal musculofascial island. One patient had a mild submandibular infection which healed after wound drainage and intravenous antibiotics. At 1 month after operation, the color and texture of the musculofascial island were similar to oral mucosa without contracture, and the occluding relation was good for all patients. At 6 months after operation, the mouth opening hardly improved in 2 patients who had osteoradionecrosis; 1 patient who underwent postoperative radiotherapy had restriction of mouth opening; the remaining 8 patients had normal month opening and normal diet. Three patients died of cancer recurrence, 2 patients died of other diseases (encephalorrhagia in 1 case and myocardial infarction in 1 case), and the others survived without recurrence during follow-up. No patient developed abdominal hernia during follow-up. Conclusion DCIA-IIOF is a reliable flap in reconstruction of complex oromandibular defects. The occluding relation after operation is good and the mucosal lining is soft. This technique provides an effective option for moderate complex oromandibular defects repair.
ObjectiveTo evaluate the clinical experiences and treatment effectiveness of chronic venous insufficiency with venous ulcer in lower limb. MethodsSeventy-eight patients (88 limbs) suffering lower limb chronic venous insufficiency with venous ulcer from May 2004 to April 2011 in this hospital were analyzed retrospectively. All the patients had undergone high ligation for great saphenous vein plus endovenous laser treatment plus subfascial endoscopic perforator vein surgery (SEPS). ResultsPostoperative complications included 3 cases of subfascial haematoma; 2 cases of pneumohypoderma; 3 cases of numbness in anterior tibial and ankle areas. All the ulcers healed between 4 to 6 weeks. Follow up period was between 6 months to 5 years. There was only one recurrence due to residual varicose from ankle area. The mean operation time was 20 min (15－30 min) in SEPS, the average blood loss was 2 ml (1－5 ml), and the mean duration of postoperative hospitalization was 5 d (2－8 d). ConclusionsSEPS is a first treatment choice for CVI with venous ulcer. It has less invasiveness, lower chances for bleeding, shorter operation time, quicker recovery, and fewer complications.
Since October 1984, we have designed a method of conversed transplant of radial styloid bone flap with fascial pedicle in the treatment of 22 patients with non-united waist fractures of carpal scaphoid. The results from follow-up of 2-7 years were satisfactory.This article introduced the design of the bone flap, the operative procedure and the advantages of the bone flap.
Objective To observe and evaluate the short-term effectiveness of superior capsular reconstruction using autologous fascia lata graft for irreparable massive rotator cuff tears. Methods The clinical data of 9 patients with irreparable massive rotator cuff tears treated with arthroscopic superior capsular reconstruction by using autologous fascia lata graft between September 2019 and April 2020 were retrospectively analysed. There were 4 males and 5 females with a median age of 66 years (range, 55-70 years). The disease duration was 6-60 months with an average of 19.1 months. According to Hamada classification, the patients were classified as grade 1 in 2 cases, grade 2 in 2 cases, grade 3 in 2 cases, and grade 4 in 3 cases. Before and after operation, the visual analogue scale (VAS) score was used to evaluate the improvement of shoulder joint pain, the American Shoulder and Elbow Surgeons (ASES) score, Constant score, and the University of California Los Angeles (UCLA) shoulder function score were used to evaluate the improvement of shoulder joint function. The active range of motion of shoulder joint was recorded, including forward flexion, abduction, lateral external rotation, and internal rotation. The changes of subacromial space were recorded by anteroposterior X-ray film of shoulder joint. Sugaya classification was used to judge the integrity of rotator cuff immediately after operation and at last follow-up. ResultsThe operation time was 210-380 minutes, with an average of 302.3 minutes. All incisions healed by first intention after operation, and there was no complication such as infection and nonunion of incisions. Two patients had numbness of the upper limbs on the surgical side after operation, and the numbness completely relieved at 6 weeks after operation; 5 cases with preoperative pseudoparalysis symptoms recovered after operation. Nine patients were followed up 12-17 months, with an average of 14.1 months. At last follow-up, the patient’s active range of motion of shoulder joint (forward flexion, abduction, lateral external rotation, and internal rotation), subacromial space distance, VAS score, ASES score, Constant score, and UCLA score significantly improved when compared with preoperative ones (P<0.05). There was no significant difference in the Sugaya classification between at last follow-up and immediately after operation (Z=?1.633, P=0.102). ConclusionSuperior capsular reconstruction using autologous fascia lata graft can restore the superior stability and achieve a good short-term effectiveness for irreparable massive rotator cuff tears.
Objective
To investigate the effect of domestic porous tantalum encapsulated with pedicled fascial flap on repairing of segmental bone defect in rabbits’ radius.
Methods
A total of 60 New Zealand white rabbits (aged 6- 8 months and weighing 2.5-3.0 kg) were randomly divided into the experimental group and control group (30 rabbits each group). A 1.5 cm segmental bone defect in right radius was established as the animal model. The porous tantalums encapsulated with pedicled fascial flaps (30 mm×20 mm) were implanted in the created bone defect in the experimental group, and the porous tantalums were only implanted in the control group. X-ray films were observed at the day after operation and at 4, 8, and 16 weeks after operation. Specimens were taken out at 4, 8, and 16 weeks after operation for HE staining and toluidine blue staining observation. The maximum load force and bending strength were detected by three point bending biomechanical test, and the Micro-CT analysis and quantitative analysis of the new bone volume fraction (BV/TV) were performed at 16 weeks after operation to compare the bone defect repair abilityin vivo in 2 groups.
Results
All incisions healed by first intention without wound infection. At 4, 8, and 16 weeks after operation, the X-ray films showed that the implants were well maintained without apparent displacement. As followed with time, the combination between the implants and host bone became more and more closely, and the fracture line gradually disappeared. HE staining and toluidine blue staining showed that new bone mass and maturity gradually increased at the interface and inside materials in 2 groups, and the new bone gradually growed from the interface to internal pore. At 16 weeks after operation, the three point bending biomechanical test showed that the maximum load force and bending strength in the experimental were (96.54±7.21) N and (91.26±1.76) MPa respectively, showing significant differences when compared with the control group [(82.65±5.65) N and (78.53±1.16) MPa respectively] (t=3.715, P=0.004; t=14.801, P=0.000). And Micro-CT analysis exhibited that there were a large amount of new bone at the interface and the surface of implant materials and inside the materials. The new bone BV/TV in the experimental group (32.63%±3.56%) was significantly higher than that in control group (25.07%±4.34%) (t=3.299, P=0.008).
Conclusion
Domestic porous tantalum encapsulated with pedicled fascial flap can increase local blood supply, strengthen material bone conduction ability, and promote the segmental bone defect repair.
ObjectiveTo investigate the application and effectiveness of split-thickness scalp graft and temporoparietal fascia flap in the low hairline auricle reconstruction in microtia patients.
MethodsBetween July 2010 and April 2015, 23 patients with low hairline microtia (23 ears) underwent low hairline auricle reconstruction. There were 16 males and 7 females with the mean age of 12 years (range, 6-34 years). The left ear was involved in 10 cases, and the right ear in 13 cases. There were 18 cases of lobule-type, 4 cases of concha-type, and 1 case of small conchatype. Referring to Nagata's two-stage auricular reconstruction method, the first stage operation included fabrication and grafting of autogenous costal cartilage framework; after 6 months, second stage operation of depilation and formation of cranioauricular sulcus was performed. The split-thickness scalp was taken from the part of the reconstructive ear above hairline. The hair follicles and subcutaneous tissue layers in hair area were cut off during operation. The area of depilation and auriculocephalic sulcus were covered with temporoparietal fascia flap. Then split-thickness skin was implanted on the surface of temporoparieta fascia flap.
ResultsAll operations were successfully completed. Healing of incision by first intention was obtained, without related complication. The patients were followed up 6-20 months (mean, 12 months). The reconstructed ear had satisfactory appearance and had no hair growth.
ConclusionThe application of splitthickness scalp graft and temporoparietal fascia flap in low hairline auricle reconstruction in microtia patients can achieve satisfactory results.
OBJECTIVE: To investigate the therapeutic effect of subfascial endoscopic perforator vein surgery (SEPS) in treatment of varicose of the lower limb. METHODS: From 1999. 11 to 2000. 12, 108 patients with varicose of the lower limb underwent venous surgery and 34 of them were treated by SEPS. There were 16 males and 18 females aged 20-79(averaged 51.4 years). Thirty limbs (26 cases) had open ulcers and the diameter of ulcer was 1.5-12.0 cm. Eleven limbs (8 cases) had severe pigmentation and the skin changes had been presented for 1 month to 15 years. According to the severity of illness, flush saphenofemoral ligation, great saphenous vein stripping, percutaneous continuous venous circum suture, external femoral vein valve repair and SEPS were performed separately or simultaneously. RESULTS: Active ulcers healed in 19 limbs after 1 month, in 7 limbs after 3 months, and in the other 4 ulcers after skin transplantation. There was no ulcer recurrence during follow-up (ranged 9-22 months). CONCLUSION: SEPS can accelerate the healing of venous ulcers, and it is one of important methods in the treatment of chronic venous insufficiency.
