BACKGROUND: The management of the surgical wound of partially impacted mandibular third molar surgery has a great impact on recovery as well as on food impact retention. The present study used clinical parameters and health-related quality of life (HRQL) to compare outcomes of cyanoacrylate application versus traditional suture of third molar impaction surgery.
METHODS: This was a retrospective observational study of subjects scheduled for outpatient third molar surgery. Each participant signed an informed consent agreement. Inclusion criteria were as follows: presence of at least one partially impacted mandibular third molar, confirmed with a preoperative panoramic radiograph. Exclusion criteria were the following: smoking, diagnosed diabetes mellitus. Between June 2020 and September 2023, a total of 78 patients of mean age 31.14 years old (range 21-40 years, standard deviation 9.14), were included in this study-38 patients were male, 40 patients were female. A group of patients received traditional silk suture (G1 = 41 patients), while the second group (G2 = 37 patients) received hemostasis performed with fibrin sponge and, after complete soaking of the sponge, the application of cyanoacrylate gel on the blood clot and suture with one 2/0 stitch in order for recovery for secondary closure. The following parameters were measured: HRQL, average pain (AP), maximum pain (MP), complication score (CS), facial swelling (FS), and erythema.
RESULTS: For HRQL parameters, oral disability was found to be significantly higher in G1 while AP was significantly higher in G2 (p < 0.05). AP was higher in G2 (p = 0.0098), as well as MP (p = 0.001). No differences were found with regards to CS (p = 0.0759). FS and erythema were higher in G1 (p < 0.0001 for facial swelling, and p = 0.0001 for erythema).
CONCLUSIONS: on the basis of this study, the use of cyanoacrylate after mandibular third molar surgery appears to be useful in order to reduce postoperative oral disability, facial swelling, and erythema after tooth extraction, with increased average and medium pain: clinicians may consider its use in selected cases.

BACKGROUND: A new access technique was developed to reduce postoperative adverse events after the extraction of impacted maxillary wisdom teeth. Hence, this study aimed to assess the occurrence of adverse events after the extraction of maxillary impacted wisdom teeth using a traditional access (TA) or a new technique (NT).
METHODS: Two different surgical incision designs were used for bilateral wisdom tooth extractions in 30 patients. The traditional incision was performed distal to the second molar in the center of the tuberosity, followed by a buccal releasing incision. After the tooth extraction, the wound was secured by sutures. The new technique consists of an oblique incision from the distal palatal aspect of the tuberosity towards the buccal aspect of the second molar. After the tooth extraction, cyanoacrylate glue was used on the wound.
RESULTS: Lower pain was reported by patients at the site treated with the new technique (p < 0.01). Edema, postsurgical bleeding, and hematoma were similar in both groups. The surgical time was shorter for the new technique (p < 0.01).
CONCLUSIONS: The new technique applied for the extraction of impacted maxillary wisdom teeth reduced postsurgical pain and the duration of surgery.

UNASSIGNED: Various techniques of closure of surgical incisions have been described ranging from various suture materials, staples and tapes to adhesive compounds. Cyanoacrylate is an adhesive compound available for surgical incision closure. Although sutures have been the preferred universal choice for surgical incision closure, glue is gaining popularity in specific places like pediatric injuries, facial injuries, laparoscopic incision closure, etc. This study aimed to compare the results between the application of cyanoacrylate and conventional suturing.
UNASSIGNED: In this randomized control study, patients were divided into two groups of 100 each. The surgical incisions were closed using cyanoacrylate glue in Group A patients and polyamide (EthilonTM 2-0) in Group B patients. Post-operative pain was assessed using Visual Analogue Scale on the first, third, and seventh day. The wounds were evaluated for complications on post-op days 1, 3, 7, and 30 using the ASEPSIS score. Cosmetic outcome was assessed at the end of first month using the Modified Hollander Cosmesis Scale.
UNASSIGNED: Post-operative pain was significantly less in the glue group on days 1, 3, and 7. Wound infection with dehiscence occurred in 4 cases (4 %) in Group A and one patient (1 %) in Group B, which was statistically insignificant. There was no significant difference in cosmetic outcomes in either Group.
UNASSIGNED: Cyanoacrylate is a good alternative to sutures in skin closure of clean and clean-contaminated surgical wounds.

Background Carpal tunnel syndrome (CTS) is caused by compression of the median nerve in the carpal tunnel. The effect of tissue adhesives as a material for wound closure following CTS decompression has been insufficiently investigated. This study aimed to evaluate outcomes by comparing two modalities of wound closure following carpal surgery in patients randomly assigned to either tissue adhesives or sutures. Methodology This randomized, prospective study was conducted in April 2022 at the University Hospital of Split in Croatia. Patients aged 61.56 ± 12.03 years were randomized to either tissue adhesive Glubran Tiss 2®-based (n = 50) or suture-based (n = 50) wound-closure techniques. The following outcomes were assessed before surgery and six months postoperatively: hand strength, electroneurographic characteristics of the median nerve, and the Boston Carpal Tunnel Questionnaire. Results Significant differences between glue-based and suture-based wound-closure techniques were found in the six-month postoperative hand grip strength (25.06 ± 6.69 vs. 21.41 ± 5.62 kg; p = 0.002), postoperative sensory amplitude (10.08 ± 5.50 vs. 7.54 ± 5.41 mV; p = 0.012), and postoperative sensory velocity (42.22 ± 11.04 vs. 35.23 ± 16.40 m/s; p = 0.008). In the glue-based group, significantly more patients achieved a postoperative sensory velocity greater than 45 m/s (47.9% vs. 22.0%; p= 0.006), postoperative distal sensory latency less than 3.5 ms (89.6% vs. 84.0%; p = 0.304), and postoperative motor latency of less than 4.2 ms (60.42% vs. 38.00%; p = 0.022). Conclusions This trial demonstrated that cyanoacrylate-based adhesion material for wound closure after open CTS decompression compared with sutures showed a significant six-month postoperative increment in hand grip strength and median nerve sensory conduction.

UNASSIGNED: Gastric variceal bleeding (GVB), compared to esophageal varices, is rare but often massive and associated with high mortality. Endoscopic cyanoacrylate glue injection (ECGI) is the first-line treatment for GVB. Hence, we conducted this study to assess the clinical outcomes and the determinants of ECGI for gastric variceal bleeding.
UNASSIGNED: This was a prospective observational study of patients with ECGI for GVB between June 2019 and February 2023. The demographic characteristics, etiology and severity of cirrhosis, size, type of gastric varices, volume of cyanoacrylate used, number of sessions required, technical success, rebleeding rate, and survival at three months were studied.
UNASSIGNED: A total of 135 patients underwent ECGI for GVB. Their mean (SD) age was 44.9 (13.6) years, with a male preponderance (n = 23, 68.1 %). Eighty-two patients (60.7 %) had cirrhosis. Their mean model for end-stage liver disease (MELD) score was 14.3 (7.3). Gastric varices were gastroesophageal varices (GOV)1 in 42 (31.1 %), GOV2 in 73 (54.1 %), and isolated gastric varices (IGV)1 in 20 (14.8 %) patients. Varices were large in 35 (25.9 %) and had F1 morphology in 89 (65.9 %) patients. The success rate of initial hemostasis was 98.5 %. The median sessions required were 1 (1-2), and the median volume of cyanoacrylate per session was 2 (1-2) ml. The procedure was associated with minor complications like transient abdominal pain in 11 (8.1 %) and fever in 2 (2.7 %) patients. Rebleeding was observed in 23 (17 %) patients. GOV2, F1 morphology, and a high MELD score were significantly associated with rebleeding. Five (3.7 %) patients died during the study; 2 (1.5 %) were due to failure to control bleeding.
UNASSIGNED: In conclusion, our study demonstrated ECGI to be very safe and effective for GVB. The technical success was high and could be achieved in fewer sessions with a smaller volume of cyanoacrylate during each session.

N-butyl cyanoacrylate (NBCA) is a lipophilic, permanent embolic glue that must be opacified for fluoroscopic guidance. Empirically, lipophilic Lipiodol Ultra Fluid® (LUF) has been added to produce a single-phase physically stable mixture. Varying the dilution ratio allows control of glue polymerization kinetics. LUF is far more costly than water-soluble iodinated contrast agents (ICAs). Our purpose was to evaluate whether a water-soluble nonionic iso-osmolar ICA could be used instead. We embolized both renal arteries of six swine using 1:3 NBCA-LUF or NBCA-iodixanol in 1:1, 1:3, and 1:7 ratios. We used both micro-computed tomography to assess the distality of glue penetration and indexed cast ratio and histology to assess distality, arterial obliteration, vessel-wall damage, and renal-parenchyma necrosis. Glue-LUF produced significantly greater indexed cast ratio and renal-artery ROI values and a significantly shorter cast-to-capsule distance. The injected volume was significantly greater with 1:7 iodixanol than with the other mixtures. No significant differences were found for histological evidence of artery obliteration, vessel-wall damage, or renal-parenchyma necrosis. This is the first study dealing with ICA alone as a contrast agent for cyanoacrylate embolization, compared to LUF. More research is needed to determine whether water-soluble nonionic iodinated agents can be used for human NBCA embolization given the good safety profile, availability, and low cost of ICA.

BACKGROUND: The present study evaluated the biomechanical characteristics of cyanoacrylate-based tissue adhesive (TA) compared to surgical sutures in coronally advanced flap (CAF) procedures using an ex-vivo model.
METHODS: Thirty-six half-pig mandibles were divided into three groups, n=12 each: (I) CAF fixed with sutures (sling and tag suture technique), (II) CAF fixed with TA, and (III) CAF fixed with sutures and TA. At mandibular premolars, gingival recession defects extending 3 mm apical to the cemento-enamel junction (CEJ) were created. CAF procedures were performed using a split-full-split approach, with coronal advancement of the flap to 1 mm above the marked CEJ and stabilization according to the respective groups I-III. Marginal flap stability against pull-of forces (maximum tensile force) was measured with a universal material testing machine until the CEJ became visible.
RESULTS: The comparison between groups I-III demonstrated a significantly increased maximum tensile force for the TA (II) compared to the suture group (I) (p<0.001). A significantly increased maximum tensile force was found for the suture and TA (III) compared to the suture group (I) (p<0.001). There was also a significantly increased maximum tensile force in the suture and TA (III) compared to the TA group (II) (p<0.001).
CONCLUSIONS: The results suggest that cyanoacrylate-based TA can increase marginal flap stability compared to sutures in CAF procedures.
CONCLUSIONS: Cyanoacrylate-based TA can be considered a useful and valuable adjunct to conventional suturing techniques in periodontal plastic surgery, especially in cases where high flap stability is required. The results of this ex-vivo study can only be transferred to the clinical situation with limitations. Clinical long-term follow-up data must be generated.

UNASSIGNED: Traditionally, sutures have been widely used to close intraoral wounds. Various alternatives have been developed amongst which newer tissue adhesives such as N-butyl-2-cyanoacrylate having accepted clinical properties are gaining popularity. The primary purpose of the present study is to evaluate the efficacy of N-butyl-2-cyanoacrylate for intraoral attached mucosal wound closure following alveoloplasty.
UNASSIGNED: In this prospective split-mouth study, 25 patients requiring alveoloplasty in either maxillary or mandibular arch bilaterally with a total of 50 sites were divided into two equal groups, namely silk suture (Group 1) and cyanoacrylate (Group 2). Each patient was evaluated on the first, third, seventh, 14th and 21st post-operative days. Parameters evaluated were time taken to close incision and to achieve haemostasis, pain, oedema, post-operative wound healing, patient discomfort and possible complications.
UNASSIGNED: Time taken to close incision, time taken to achieve haemostasis, post-operative pain and oedema were found to be less in Group 2. Wound healing too was found to be better in Group 2. There was one case of adhesive peel off on the first post-operative day which was managed by reapplying the tissue adhesive. The incidence of wound dehiscence and wound infection was observed more in Group 1 on the third post-operative day. Suture breakage (16%) and adhesive dislodgement (8%) were reported on the seventh post-operative day.
UNASSIGNED: The use of cyanoacrylates\' inherent benefits, such as improved wound seal off in attached mucosa, quick polymerisation and bacteriostatic characteristics can be beneficial when performing minor oral surgical procedures on elderly, young and mentally challenged patients.

First, it has been demonstrated that endoscopic ultrasonography (EUS)-guided cyanoacrylate (CYA) injection (EUS-CYA) has greater efficacy than direct endoscopic injection of cyanoacrylate (DEI-CYA) for treating type 1-isolated gastric varices. However, it is necessary to conduct further studies to determine whether EUS has any advantage over the current guidelines for treating gastroesophageal varices type 1 (GOV1). Second, liver function is an important prognostic factor in patients with liver cirrhosis. Therefore, we evaluated the liver function of patients treated with EUS-CYA.
In a single-center study, a prospective cohort from February 2021 to September 2022 involving 89 patients with cirrhosis with GOV1 were assigned to undergo EUS-CYA (n = 45) or DEI-CYA (n = 44). The success rate of CYA injection, the rate of overall rebleeding, the rate of reintervention, the complications during the follow-up period, and the liver function were compared.
In both groups, 100% of the operations were successful. The follow-up time of the two groups was 290 (153-398) days and 267 (177-416) days, respectively. In the EUS group, the perforating veins had an average diameter of 7.0 ± 2.7 mm, and they had a 100% occlusion rate. A statistically significant difference was found between the two groups regarding the number of sessions needed to eradicate GV (p = 0.005, pairwise comparisons were conducted using the Bonferroni correction method.), the late rebleeding rate after EUS-CYA [n = 3 (6.7%) vs n = 10 (22.7%); p = 0.032], and the incidence of postinjection ulcers [n = 4 (8.9%) vs n = 12 (27.3); p = 0.023)]. Following EUS or DEI-CYA treatment, the patient\'s liver function did not show any significant deterioration or decline.
EUS-CYA has a higher eradication success rate and fewer complications, recurrences, and rebleeding episodes than DEI-CYA used for GOV1 treatment. In addition, EUS-CYA did not impair liver function.

OBJECTIVE: In this study, we present the complication data of patients we treated for chronic venous insufficiency (CVI) with cyanoacrylate adhesive closure (CAC) therapy for 2 years.
METHODS: Complications of 382 CAC procedures performed by the same surgeon were reviewed retrospectively.
RESULTS: Independent of patients, depending on the payment system of the state; two hundred twenty-three (58.4%) of 382 procedures were performed using the Venex system, and the Variclose system was used in 159 (41.6%) patients. A phlebitis-like reaction occurred in 46 (12%) patients, induration in 18 (4.7%) patients, hyperpigmentation in five (1.3%) patients, abscesses in four (1%) patients, cellulitis in three (0.8%) patients, and granuloma in one (0.3%) patient. In addition, as serious complications, deep vein thrombosis (DVT) developed in three patients and pulmonary embolism in one of these patients. Interestingly, temporary blindness was also observed in one patient.
CONCLUSIONS: Although CAC therapy is a reliable method, its complications should not be ignored. Its use by experienced surgeons reduces the risk of complications.
