RESUMEN
Objective To discuss the application of gelatin sponge-hemocoagulase plugging agent in patients with pulmonary puncture bleeding.Methods The clinical data of 43 patients with hemorrhage caused by DSA-guided lung puncture biopsy,who received gelatin sponge-hemocoagulase plugging agent treatment at the Jining Municipal First People's Hospital of China between September 2021 and May 2023,were collected,and the hemostatic effect of gelatin sponge-hemocoagulase plugging agent was analyzed.Results Successful lung puncture needle biopsy was achieved in all the 43 patients.The puncture needle channel occlusion was accomplished by using gelatin sponge-hemocoagulase plugging agent.Five minutes after occlusion treatment,in one patient,whose moderate hemoptysis with moderate bleeding shadow before puncture needle biopsy changed to bloody sputum,the intrapulmonary bleeding shadow displayed on image became slightly enlarged when compared the size five minutes ago,while in all the remaining patients successful hemostasis was achieved,the hemoptysis disappeared and the pulmonary hemorrhage shadow was similar to that five minutes ago.No occlusion-related complications occurred in all patients.Conclusion For the treatment of pulmonary hemorrhage caused by DSA-guided lung puncture biopsy,gelatin sponge-hemocoagulase plugging agent is clinically safe and effective.
RESUMEN
Objective To compare the clinical efficacy and safety of gelatin sponge particles,gelatin sponge strips,and spring coil combined with gelatin sponge particles in preoperative interventional embolization for spinal tumors.Methods The clinical data of a total of 92 patients with spinal tumor,who received preoperative interventional embolization before spinal tumor surgery at the Affiliated Zhongshan Hospital and Xiamen Branch of Fudan University of China between June 2012 and June 2022,were collected.According to the different embolization materials used during the interventional embolization,the patients were divided into gelatin sponge particle group(ni=36),gelatin sponge strip group(n=36),and spring coil plus gelatin sponge particle group(n=20).Kruskal-Wallis testing was used to compare the intraoperative bleeding volume among the three groups,and Fisher's exact probability testing was used to compare the incidence of complications among the three groups.Results Successful surgical resection of the spinal tumor was accomplished in all patients.The median intraoperative bleeding volumes in gelatin sponge particle group,gelatin sponge strip group,and spring coil plus gelatin sponge particle group were 400 mL(200-950 mL),1 000 mL(513-2000 mL),and 1000 mL(500-1350 mL)respectively.The intraoperative bleeding volume in the gelatin sponge particle group was significantly smaller than that in the gelatin sponge strip group(P=0.000 8)and in the spring coil plus gelatin sponge particle group(P=0.002 7),the differences were statistically significant.After operation,4 patients in the gelatin sponge particle group developed incision infection or local abscess formation,one patient in the gelatin sponge strip group developed incision dehiscence,and one patient in the spring coil plus gelatin sponge particle group had postoperative local hematoma at the incision site.No statistically significant difference in the incidence of complications existed between each other among the three groups(all P>0.05).Conclusion For interventional embolization of spinal tumor,all of the gelatin sponge particles,gelatin sponge strips,and spring coils are clinically safe and effective.However,in reducing the amount of blood loss during surgery the superselective catheterization with embolization of tumor-feeding arteries using gelatin sponge particles is superior to the non-superselective catheterization with embolization of tumor-feeding arteries using gelatin sponge strips or combination use of gelatin sponge particles and spring coils.(J Intervent Radiol,2023,32:1184-1189)
RESUMEN
Introduction: Endo-periodontal lesions can lead to the formation of severe intraosseous defects in the periodontium; which can lead to tooth loss. Objective: Demonstrate that surgical periodontal therapy with the help of gelatin sponges, with colloidal silver nanoparticles, restores bone tissue lost in endo-periodontal lesions. Case presentation: 55-year-old male patient without systemic alterations, diagnosed with grade 3 endo-periodontal lesion in patients with periodontitis. It was treated first with ducts and then with periodontal surgery combined with gelatin sponges, which contain colloidal silver nanoparticles, and were placed filling the 2-wall bone defect involving > 80 percent of the root length, with 24 months of radiographic and clinical follow-up.

Abstract Introduction Traumatic large tympanic membrane perforations usually fail to heal and require longer healing times. Few studies have compared the healing and hearing outcomes between gelatin sponge patching and ofloxacin otic solution. Objectives To compare the healing outcomes of large traumatic tympanic membrane perforations treated with gelatin sponge, ofloxacin otic solution, and spontaneous healing. Methods Traumatic tympanic membrane perforations >50% of the entire eardrum were randomly divided into three groups: ofloxacin otic solution, gelatin sponge patch and spontaneous healing groups. The healing outcome and hearing gain were compared between the three groups at 6 months. Results A total of 136 patients with large traumatic tympanic membrane perforations were included in analyses. The closure rates were 97.6% (40/41), 87.2% (41/47), and 79.2% (38/48) in the ofloxacin otic solution, gelatin sponge patch, and spontaneous healing groups, respectively (p = 0.041). The mean times to closure were 13.12 ± 4.61, 16.47 ± 6.24, and 49.51 ± 18.22 days in these groups, respectively (p < 0.001). Conclusions Gelatin sponge patch and ofloxacin otic solution may serve as effective and inexpensive treatment strategies for traumatic large tympanic membrane perforations. However, ofloxacin otic solution must be self-applied daily to keep the perforation edge moist, while gelatin sponge patching requires periodic removal and re-patching.
Resumo Introdução As grandes perfurações traumáticas da membrana timpânica geralmente apresentam falha de cicatrização e requerem tempos de cicatrização mais longos; poucos estudos compararam os resultados de cicatrização e a audição dessas perfurações obtidos com curativo de Gelfoam® e solução otológica de ofloxacina. Objetivo Comparar os resultados de cicatrização de grandes perfurações traumáticas da membrana timpânica tratadas com Gelfoam®, solução otológica de ofloxacina e cicatrização espontânea. Método Perfurações traumáticas de > 50% de todo o tímpano foram divididas aleatoriamente em três grupos: tratamento com solução otológica de ofloxacina, com curativo de Gelfoam® e grupo de cicatrização espontânea. O resultado da cicatrização e o ganho auditivo foram comparados entre os três grupos após 6 meses. Resultados Foram incluídos nas análises 136 pacientes com grandes perfurações traumáticas de membrana timpânica. As taxas de cicatrização foram de 97,6% (40/41), 87,2% (41/47) e 79,2% (38/48) com a solução otológica de ofloxacina, curativo de Gelfoam® e grupos de cicatrização espontânea, respectivamente (p = 0,041). O tempo médio de cicatrização foi de 13,12 ± 4,61, 16,47 ± 6,24 e 49,51 ± 18,22 dias nesses grupos, respectivamente (p < 0,001). Conclusões O curativo de Gelfoam® e a solução otológica de ofloxacina podem servir como estratégias de tratamento eficazes e de baixo custo para grandes perfurações traumáticas de membrana timpânica. Entretanto, a solução otológica de ofloxacina deve ser autoaplicada diariamente para manter a borda da perfuração úmida, enquanto o curativo de Gelfoam® requer sua remoção e reaplicação periódicas.

BACKGROUND: Hemorrhage control has been an important issue in spine surgery. The widely used gelatin sponge is limited by its long-time bleeding control and poor hemorrhage control. Therefore, new techniques are needed to control bleeding in spine surgery. OBJRCTIVE: To compare the hemostatic effect of fluid gelatin Surgiflo™ with absorbable gelatin sponge in single level posterior lumbar fusion surgery. METHODS: Ninety-eight patients consisting of 52 males and 46 females, aged 54. 32 years who received treatment between September 2017 and December 2017 in Xijing Hospital of The Fourth Military Medical University were included in this study. All patients underwent single-level L4/5 lumbar fusion. Among them, 48 patients received intraoperative hemostasis with fluid gelatin SurgifloTM and 50 patients received intraoperative hemostasis with conventional gelatin sponge. Intraoperative bleeding volume, postoperative drainage volume, success rate of hemostasis in 3 minutes and changes of hemoglobin levels in perioperative period were compared between the two groups. RESULTS AND CONCLUSIONS: The operation time in the Surgiflo™group was significantly shorter than that in the gelatin sponge group [(105±26) vs. (118±32) min, P < 0. 05]. The amount of intraoperative blood loss and total amount of drainage were (156±57) mL and (106±42) mL in the Surgiflo™group which were significantly lower than those in the gelatin sponge group [(204±62) mL, (148±35) mL, P < 0. 05]. The success rate of hemostasis within 3 minutes in the Surgiflo™ group was significantly higher than that in the gelatin sponge group (94% vs. 80%, P < 0. 05). The change in hemoglobin level during the perioperative period relative to pre-surgery level was significantly higher in the Surgiflo™ group was significantly lower than that in the gelatin sponge group [(12. 3±3. 6) vs. (22. 8±4. 3) g/L, P < 0. 05]. No complications such as anaphylaxis, immune rejection, or delayed hematoma occurred in both groups. These results suggest that fluid gelatin Surgiflo™ can significantly reduce intraoperative blood loss and postoperative drainage volume in single-level lumbar fusion surgery and exhibit better hemostatic effects.
RESUMEN
Objective: The objective of this study is to investigate the effect of ethanol-soaked gelatin sponge (ESG) in the treatment of hepatic arterioportal shunt (APS). Methods: Hepatocellular carcinoma (HCC) patients with APS were divided into experimental group (Group E) and control group (Group C). Patients in Group E were treated with ESG for APS embolization, whereas patients in Group C were treated with polyvinyl alcohol particles for APS embolization, with other treatment unchanged. APS and the Eastern Cooperative Oncology Group (ECOG) physical status scores of patients before and after the first treatment and further consultation in the 6th week and the survival rate in follow-up visit were recorded. The changes of liver function during treatment were monitored. Results: Before the first treatment, there was no statistical significant difference in APS between two groups. After that, APS in Groups E (P = 2.49 × 10−7) and C (P = 2.10 × 10−4) was improved. In further consultation, APS in Groups E (P = 2.73 × 10−13) and C (P = 2.90 × 10−8) was further improved after examinations and corresponding treatment. After the first treatment and further consultation, APS score was lower in Group E than in Group C, and there were still five patients whose APS score was 2 in Group C. Quality of life in two groups was effectively controlled without getting worse and the ECOG score reduced. Liver function in the two groups did not worsen with the use of liver protective drugs. No deaths occurred in Group E, whereas two patients died in Group C during treatment and follow-up visit. Conclusion: The results show that ESG can effectively reduce APS score and improve the survival rate of HCC patients
RESUMEN
Objective@#To investigate the preventive effects of gelatin sponge debris pre-filling on bone cement leakage during percutaneous kyphoplasty (PKP) for vertebral osteoporotic fracture with cortical bone rupture.@*Methods@#The data of 256 cases (294 segments) of osteoporotic vertebral compression fracture (OVCF) treated with PKP from January 2014 to July 2016 were retrospectively analyzed. There were 106 segments in 92 males and 188 segments in 164 females. In 119 cases, a total of 132 segments were pre-filled with gelatin sponge debris before bone cement injection. The average age was 74.4±7.7 years. In 137 cases, 162 segments were not pre-filled with gelatin sponge debris, with average age of 73.3±6.4 years. The incidences of cement leakage, visual analogue scale (VAS), Oswestry disability index (ODI), the change of anterior vertebral height and kyphosis angle before and after operation were compared between the two groups.@*Results@#In gelatin sponge group, the incidence of cement leakage was 12.6% (15/119), including 3.4% (4/119), 0.8% (1/119), 1.7% (2/119), 5.0% (6/119) and 1.7% (2/119) of the endplate type, the lateral type, the anterior type, the posterior type and the mixed type. The incidence of cement leakage in non-gelatin sponge group was 23.4% (32/137), including 4.4% (6/137), 5.1% (7/137), 5.1% (7/137), 5.8% (8/137) and 2.9% (4/137) of the endplate type, the lateral type, the anterior type, the posterior type and the mixed type. The difference of total cement leakage rate between the two groups was significant (χ2=4.912, P=0.027). There was no significant difference in leakage rates among different types (P>0.05). Postoperative symptoms were improved in both groups. VAS score and ODI index were improved at 1, 3 and 6 months after operation (P<0.05). However, there was no significant difference in VAS score and ODI index at preoperative and post-operative follow-up between groups. There were no significant difference between the two groups in the height of the anterior edge of the injured vertebra before operation (17.3±3.2 mm, 17.5±5.4 mm), the kyphosis angle before operation (18.9°±2.0°, 18.7°±2.3°), the height of the anterior edge of the injured vertebra after operation (22.7±3.6 mm, 22.4±5.4 mm), and the kyphosis angle after operation (11.2°±1.4°, 11.9°±1.8°).@*Conclusion@#Gelatin sponge debris pre-filling can effectively reduce bone cement leakage after PKP in patients with vertebral cortical bone rupture. There was no significant effect on the improvement of symptoms after PKP.
RESUMEN
Ultraselective conventional transarterial chemoembolization (cTACE), defined as cTACE at the most distal portion of the subsubsegmental hepatic artery, is mainly performed for hepatocellular carcinoma (HCC) ≤5 cm. Distal advancement of a microcatheter enables injection of a larger volume of iodized oil into the portal vein in the limited area under non-physiological hemodynamics. As a result, the reversed portal flow into the tumor through the drainage route of the tumor that occurs when the hepatic artery is embolized is temporarily blocked. By adding gelatin sponge slurry embolization, both the hepatic artery and portal vein are embolized and not only complete necrosis of can be achieved. Ultraselective cTACE can cure small HCCs including less hypervascular tumor portions and replace surgical resection and radiofrequency ablation in selected patients.

Objective: To investigate the influence of gelatin sponge microparticles-TACE (GSMs-TACE) on myeloid-derived suppressor cells (MDSCs) in peripheral blood of patients with Barcelona clinic liver cancer (BCLC) classification stage B hepatocellular carcinoma (HCC). Methods: Five patients with clinically diagnosed BCLC B-stage HCC (HCC group) underwent GSMs-TACE. Flow cytometry was used to detect the frequency of MDSCs (the proportion of MDSCs clusters to HLA-DR-cell) in the peripheral blood of patients before GSMs-TACE and 10 days as well as 30 days after operation, respectively. Seven healthy volunteers (normal control group) were enrolled. The MDSCs frequency of normal control group was detected simultaneously with HCC group before GSMs-TACE. Statistical analysis was performed to compare the differences of the frequency of MDSCs in HCC patients before and after GSMs-TACE. And the frequency of MDSCs of HCC group was compared with that of normal control group. Results: The frequency of MDSCs in peripheral blood of patients with HCC before GSMs-TACE was (30.26±12.12)%, which decreased to (10.22±3.79)% after 10 days and decreased to (7.33±3.38)% after 30 days (P<0.001). Pairwise comparison showed that the frequency of MDSCs at 30 days (P<0.001) and 10 days (P=0.011) after GSMs-TACE was lower than that before operation,respectively. The frequency of preoperative MDSCs of HCC group was statistically higher than that of normal control group ([30.26±12.12]% vs [3.41±1.89]%, t=5.876, P<0.001). Conclusion: The frequency of MDSCs in peripheral blood of patients with BCLC B-stage HCC significantly reduced after GSMs-TACE treatment. GSMs-TACE treatment has positive regulation effect on the immune function of patients.

Objective To evaluate the feasibility of using gelatin sponge to reduce bone cement leakage in percutaneous vertebroplasty (PVP).Methods A retrospective case control study was conducted to analyze the 191 patients (191 vertebrae) with lumbar osteoporosis vertebrae compression fractures (OVCF) who were treated by PVP from October 2014 to October 2017 in Xi'an Honghui Hospital.There were 52 males and 139 females,aged 65-91 years,with an average of 75.1 years.A total of 48 patients were treated with routine PVP,and bone cement was injected directly after puncture (Group A).A total of 47 patients,49 patients and 47 patients were injected with 1/4,1/3 and 1/2 gelatin sponge before bone cement injection respectively (Group B,Group C and Group D).Postoperative routine X-ray and CT scans were used to compare the amount of bone cement injection,the leakage of bone cement,the visual analogue score (VAS),neurological symptoms and complications before and after operation.Results All patients were followed up for 1-12 months,with an average of 3.6 months.There were no significant differences in the amount of bone cement injection after operation between groups (P > 0.05).There was a significant difference in the cement leakage rate among the groups after operation [Group A:42% (20/48);Group B:40% (19/47);Group C:14% (7/49);Group D:13% (6/47)] (P < 0.05).The results of pairwise comparison of bone cement leakage rate were as follows:significant differences were found between Group A and Group C as well as between Group A and Group D (P < 0.008 3),but no significant difference was found between Group A and Group B (P > 0.008 3);significant differences were found between Group B and Group C as well as between Group B and Group D (P < 0.008 3),but no significant difference was found between Group C and Group D (P > 0.05).There were no significant differences in VAS among the groups (P > 0.05);VAS was significantly improved after operation within each group (P < 0.05).After operation,two patients had persistent lower back pain and one patient had intraspinal leakage.Wound healing was found in all patients,with no neurological symptoms.Conclusion For OVCF,use of 1/3 or 1/2 gelatin sponge in PVP can reduce bone cement leakage.
RESUMEN
Objective To investigate the effect of embolization with ethanol-soaked gelatin sponge for the treatment of arterioportal shunting (APS) in patients with hepatocellular carcinoma (HCC). Methods From January 2016 to June 2017, a total of 78 patients with unresectable HCC were enrolled in this study. These patients were randomly divided into two groups by digital random method. The experimental group (n=39) received transarterial embolization of the shunt with ethanol-soaked gelatin sponge, while the control group (n=39) received only gelatin sponge shunt. Both of the two groups underwent transarterial chemoembolization if available. Changes in APS, tumor response (according to modified response evaluation criteria in solid tumor), changes in Eastern Cooperative Oncology Group (ECOG), and haemodynamics changes of the portal vein were analyzed. χ2 test and t test were used to compare the differences of qualitative and quantitative parameters between two groups. The APS grades were compared between the two groups before treatment and 2 months after treatment using rank sum test. Results Six patients were lost during the 2-month follow-up, and 72 patients were followed up, which include 38 patients in the experimental group and 34 patients in the control group. Compared to (14/34), the experimental group (25/38) has higher The APS improvement rates of the experimental group and the control group were 65.8%(25/38) and 41.2%(14/34), and there was significant difference (χ2=4.379, P<0.05). Of the 72 patients, 66 cases were conform to modified response evaluation criteria in solid tumor, which include 35 patients in the experimental group and 31 patients in the control group. Tumor response at 2 months of the experimental group and the control group were 57.1%(20/35) and 32.3%(10/31), and there was significant difference (χ2=4.106, P<0.05). The ECOG score was significantly decreased from 2 points to ≤1 point in 19 cases in the experimental group, while 12 cases in the control group (χ2=6.894, P<0.05). Compared with the control group, the diameter of the portal vein dropped significantly (t=2.082, P<0.05), while the blood flow velocity of portal vein increased (t=2.219, P<0.05) obviously in the experimental group 1 month after treatment. Conclusion Tansarterial embolization with ethanol-soaked gelatin sponge can effectively improve APS improvement rate, and quality of life of patients with unresectable HCC accompanied with APS.
RESUMEN
Heterotopic ossification (HO) around the hip joint is not uncommon following neurological injury. Often, surgical treatment is performed in patients with restricted motion and/or refractory pain due to grade III or IV HO according to Brooker classification. The major complication that occurs as a result of surgical HO removal is perioperative bleeding due to hyper-vascularization of the lesion. Here, we report a case of preoperative embolization in a 51-year-old male patient presenting with restricted bilateral hip range of motion (ROM) due to HO following a spinal cord injury. In the right hip without preoperative arterial embolization, massive bleeding occurred during surgical removal of HO. Thus, the patient received a transfusion postoperatively due to decreased serum hemoglobin levels. For surgery of the left hip, preoperative embolization of the arteries supplying HO was performed. Surgical treatment was completed without bleeding complications, and the patient recovered without a postoperative transfusion. This case highlights that, while completing surgical removal for ROM improvements, orthopedic surgeons should consider preoperative arterial embolization in patients with hip HO.

RESUMEN
OBJECTIVE: To investigate the effects of Kangfuxin solution combined with Chuangyangling and gelatin sponge on dry socket disease in patients with type 2 diabetes mellitus after the extraction of impacted teeth. METHODS: A total of 85 patients with impacted teeth and type 2 diabetes mellitus during Jan. 2016-Jan. 2017 were divided into group A (29 cases), B (25 cases), C (31 cases) according to random number table. All patients were treated with turbine drill method; in group A, Kangfuxin solution + Absorbable gelatin sponge was used to fill the wound site; in group B, Chuangyangling+compound preparation of Kangfuxin solution and gelatin sponge were used to fill the wound site; in group C, the wounds were filled with gauze but without any drugs. All patients received routine anti-infective treatment after surgery for 5-7 d. The time of impacted teeth extraction was observed in 3 groups; granulation tissue coverage integrity rate of tooth socket and the incidence of dry socket disease 7 d after surgery, the incidence of other postoperative complications, treatment cost, satisfaction scores were also comparod. RESULTS: There was no statistical significance in the time of impacted teeth extraction or treatment cost among 3 groups (P>0. 05). Seven days after surgery, granulation tissue coverage integrity of tooth socket and satisfaction scores were in descending order: group B>group A>group C; the incidence of dry sockets were in ascending order: group B<group A<group C, with statistical significance (P<0. 05). The incidence of other postoperative complications as bleeding, pain, swelling, limitation of mouth opening in group A and B were significantly lower than group C, with statistical significance (尸<0. 05). There were no statistical significance between group A and B (P>0. 05). CONCLUSIONS: Kangfuxin solution combined with Chuangyangling and gelatin sponge can effectively increase granulation tissue coverage integrity of tooth socket, and reduce the incidence of dry socket disease and other postoperative complications in patients with type 2 diabetes mellitus, but do not increase economic burden of patients and obtain high patient satisfaction.
RESUMEN
OBJECTIVE To compare two administration methods of triamcinolone acetonide cream for the treatment of ear mycosis with pevison. METHODS Eighty-six cases diagnosed as the external auditory canal fungal infections with tympanic membrane perforation were randomly divided into observation group and control group, with 43 cases in each group. All the selected patients were positive in the external auditory meatal secretions fungus detection test, fungi and secretions of the external auditory canal are thoroughly cleaned under the endoscope. After ear canal cleaning, the obervation group was treated with Pevisone smeared on gelatin sponge which was evenly placed on the external auditory canal with fungal infection. The control group was treated with Pevisone smearing on external auditory canal by the patients themselves, twice a day. Two groups of patients come to the hospital every 3 days for review. After 2 weeks of treatment, the patients were followed up for 3 months, and the clinical efficacy of each group was compared. RESULTS The observation group was cured in 39 cases(90.7%), effective in 2 cases(4.7%), and ineffective in 2 cases(4.7%), The total efficiency rate is 95.3%.1 case recurred at 3 months of follow-up(2.4%). While in the control group, it was cured in 26 cases(60.5%), effective in 1 cases(2.3%), and ineffective in 16 cases(37.2%), the total efficiency rate is 62.8%.9 cases recurred at 3 months of follow-up(31.0%). The effect of the observation group was significantly higher than that of the control group(x2=14.508, P<0.05). CONCLUSION The ear endoscope can be used to remove the external auditory canal fungus thoroughly and has good visibility. Treating external auditory canal fungi disease with tympanic membrane perforation with gelatin sponge coated with triamcinolone acetonide cream has better clinical efficacy.

<p><b>OBJECTIVE</b>To compare the hemostatic effect between absorbable hemostatic fluid gelatin (HFG) and absorbable gelatin sponge(GS) during operation of unilateral open-door cervical expansive laminoplasty.</p><p><b>METHODS</b>The clinical data of 83 patients underwent unilateral open-door cervical expansive laminoplasty from February 2014 to May 2016 were retrospectively analyzed. According to the used hemostatic materials, patients were divided into two groups. In HFG group, there were 30 males and 11 females, ranging in age from 29 to 81 years, with an average of(55.6±11.6)years; 14 cases were simple cervical spinal stenosis, 9 were cervical spinal stenosis and ossification of posterior longitudinal ligament, and 18 were cervical spinal stenosis complicated with multiple cervical disc herniation. And in GS group, there were 32 males and 10 females, ranging in age from 36 to 78 years, with an average of (55.4±11.1) years; 12 cases were simple cervical spinal stenosis, 10 were cervical spinal stenosis complicated with ossification of posterior longitudinal ligament, and 20 were cervical spinal stenosis complicated with multiple cervical disc herniation. There was no significant difference in the age, gender, and disease categories of patients between two groups (>0.05). The operative time, intraoperative bleeding, postoperative drainage, and postoperative complications were compared between two groups.</p><p><b>RESULTS</b>The average operative time, intraoperative bleeding, and postoperative drainage in HFG group were(137.2±30.0) min, (156.1±74.6) ml, and (212.1±67.6) ml, respectively; and in GS group were (154.8±33.5) min, (242.9±120.7) ml, and(303.3±115.5) ml, respectively. There were significantly differences in above items between two groups(<0.05). No acute heamatoma or related complications was found postoperatively.</p><p><b>CONCLUSIONS</b>Compared with GS, HFG can obviously decrease operative time, intraoperative bleeding, and postoperative drainage. It is a safe and effective hemostatic material for the operation of unilateral open-door cervical expansive laminoplasty.</p>
RESUMEN
<p><b>OBJECTIVE</b>To explore the role and mechanism of drug delivery systems using growth factor combined with gelatin sponge on accelerating the healing of jaw fracture and to seek better treatment of accelerating the maxillofacial fracture.</p><p><b>METHODS</b>About 100 μg recombinant human bone morphogenetic protein (BMP)-2 was completely dissolved in 1 mL recombinant bovine basic fibroblast growth factor (bFGF), and the solution (40 μL) was dropped in gelatin sponge (0.5 cm×0.5 cm×1.0 cm). Then, it was freeze dried and prepared into bFGF/BMP/gelatin sponge delivery systems. The mandibular fracture model on two sides were prepared in 12 New Zealand rabbits and randomly divided into two groups. The left side was the control group, which was only fixed with titanium plates. The right side was the experimental group, in which bFGF/BMP/gelatin sponge delivery systems were put under the titanium plates. General observation, X-ray, and histological examination were taken at 2, 4, and 12 weeks after surgery.</p><p><b>RESULTS</b>After 2 weeks, more fibrous tissues were seen between the fracture ends in the experimental group than in the control group. After 4 weeks, fibrous fracture callus were seen in the fracture gap in the experimental group. The ingrowths of fibrous tissue and blood vessels were seen in the control group. The fracture healing of the experimental group was significantly faster than the control group at 2 and 4 weeks. After 12 weeks, the experimental and control groups all healed completely.</p><p><b>CONCLUSIONS</b>bFGF/BMP/gelatin sponge can accelerate and improve fracture healing; thus, it has better clinical application prospect.</p>
