Update of the classification of midpalatal suture behaviour after surgically assisted rapid maxillary expansion using computed tomography.

The aim of this study was to update the midpalatal suture classification after surgically assisted rapid maxillary expansion (SARME) using computed tomography (CT). Thirty-five patients with a transverse maxillary deficiency and unilateral or bilateral posterior crossbite underwent SARME with osteotomy of the pterygoid apophysis of the sphenoid. CT was performed before installation of the Hyrax expander appliance and after the final activation. Opening of the midpalatal suture was classified into three types: type I, total midpalatal suture opening from anterior nasal spine (ANS) to posterior nasal spine (PNS); type II, partial midpalatal suture opening from ANS to the transverse palatine suture, with partial or non-existent opening of the midpalatal suture posterior to the transverse palatine suture; type III, complete maxillary opening from ANS, but not of PNS, because a paramedian fracture completed the opening of the hard palate. Type I was observed in 42.8% of the patients, type II in 40%, and type III in 17.2%. Opening of the transverse palatine suture was found in all midpalatal suture opening patterns and was more frequent in type III, followed by type II and type I. CT was used to update the classification of midpalatal suture patterns, with the inclusion of type III: total opening of the hard palate due partly to opening of the midpalatal suture and partly to a paramedian fracture.

Evaluation of Bacterial Colonization and Clinical Properties of Different Suture Materials in Dentoalveoler Surgery.

PURPOSE: This study aimed to compare the effects of 10 different suture materials commonly used in dentoalveolar surgery on wound healing, their postoperative microbial colonization, and related clinical parameters. METHODS: A total of 172 suture samples from patients who had undergone extraction of impacted third molars were included in the study. The suture materials studied were poly-glycolide-colactide, fast absorbable poly-glycolide-colactide, poly-glycolic acid-cocaprolactone, polydioxanone, silk, polypropylene, polyvinylidene difluoride, polyamide, polyester, and polytetrafluoroethylene (PTFE). The microbial colonization in all sutures and clinical parameters were evaluated after 1 week. RESULTS: Multifilament sutures had higher bacterial colonization compared with monofilament sutures (P < .001). No dental plaque accumulation was observed in any samples of polypropylene sutures. Polydioxanone, PTFE, and poly-glycolic acid-cocaprolactone sutures exhibited less postoperative slack compared with all other sutures after 1 week. Patients with silk, polyvinylidene difluoride, and PTFE sutures had less suture-related discomfort. According to the Landry index score, monofilament sutures demonstrated superior wound healing to multifilament sutures (P = .019). In addition, nonabsorbable sutures showed significantly better wound epithelization than absorbable sutures (P ˂ .001). CONCLUSIONS: Bacterial colonization and tissue reactions due to the surface properties of the suture affected the wound healing after dentoalveolar surgery. Multifilament sutures should not be applied for prolonged periods because of their tendency for microbial colonization. The tissue reaction to the absorbable suture materials may adversely affect wound healing.

Comparison of fertility outcomes after laparoscopic myomectomy for barbed versus nonbarbed sutures.

OBJECTIVE: To assess the impact on women's reproductive outcomes of barbed sutures to repair uterine breaches during laparoscopic myomectomy compared with traditional smooth sutures. DESIGN: Retrospective, monocentric cohort study, with information on subsequent pregnancies prospectively acquired for some women. SETTING: Tertiary-level academic referral center. PATIENT(S): Women older than 18 years who had undergone a laparoscopic myomectomy and had sought pregnancy afterward, divided into two groups based on type of suture used to repair the uterine wall: group A (nonbarbed) and group B (barbed). INTERVENTION(S): Laparoscopic removal of FIGO types 3, 4, 5, and 6 uterine leiomyomas by use of either only barbed sutures or only traditional smooth sutures to reconstruct the uterine defect. MAIN OUTCOME MEASURE(S): Pregnancy achievement rates, delivery modes, main pregnancy complications, perioperative complications for both kinds of suture, and the trend of the use of barbed sutures over time at our center. RESULT(S): Of 164 patients included, 83 were in group A and 81 in group B. Ninety-one patients (55.5%) experienced at least one postoperative pregnancy, with no differences between the groups (group A 60.5%; group B 50.6%). Of the 103 recorded postoperative pregnancies, 70 (68%) resulted in live births, 29 (28.1%) in first-trimester miscarriages, and 4 (3.9%) were ongoing. CONCLUSION(S): Barbed sutures have a similar impact on reproductive outcomes as smooth conventional threads, both in terms of pregnancy and obstetric complication rates, after laparoscopic myomectomy.

Randomized trial comparing suture button with single 3.5 mm syndesmotic screw for ankle syndesmosis injury: similar results at 2 years.

Background and purpose - Better outcomes are reported for suture button (SB) compared with syndesmotic screws (SS) in patients treated for an acute ankle syndesmotic injury. One reason could be that screws are more rigid than an SB. A single tricortical 3.5 mm syndesmotic screw (TS) is the most dynamic screw option. Our hypothesis is that 1 SB and 1 TS provide similar results. Therefore, in randomized controlled trial, we compared the results between SB and TS for syndesmotic stabilization in patients with acute syndesmosis injury. Patients and methods - 113 patients with acute syndesmotic injury were randomized to SB (n = 55) or TS (n = 58). The American Orthopedic Foot & Ankle Society (AOFAS) Ankle-Hindfoot Score was the primary outcome measure. Secondary outcome measures included Manchester Oxford Foot Questionnaire (MOXFQ), Olerud-Molander Ankle score (OMA), visual analogue scale (VAS), EuroQol- 5D (EQ-5D), radiologic results, range of motion, complications, and reoperations (no implants were routinely removed). CT scans of both ankles were obtained after surgery, and after 1 and 2 years. Results - The 2-year follow-up rate was 84%. At 2 years, median AOFAS score was 97 in both groups (IQR SB 87-100, IQR TS 90-100, p = 0.7), median MOXFQ index was 5 in the SB group and 3 in the TS group (IQR 0-18 vs. 0-8, p = 0.2), and median OMA score was 90 in the SB group and 100 in the TS group (IQR 75-100 vs. 83-100, p = 0.2). The syndesmotic reduction was similar 2 years after surgery; 19/55 patients in the SB group and 13/58 in the TS group had a difference in anterior syndesmotic width ≥ 2 mm (p = 0.3). 0 patients in the SB group and 5 patients in the TS group had complete tibiofibular synostosis (p = 0.03). At 2 years, 10 TS were broken. Complications and reoperations were similar between the groups. Interpretation - We found no clinically relevant differences regarding outcome scores between the groups. TS is an inexpensive alternative to SB.

Adherencia bacteriana en los materiales de sutura de uso habitual en cirugía bucal. Revision sistemática / Bacterial aggregation in the suture materials usually used in oral surgery. Systematic review

OBJETIVO: Demostrar la existencia de agregación bacteriana a los materiales de sutura que suelen emplearse en la práctica odontológica, comprobar si dicha agregación está relacionada con la inflamación que sucede al acto quirúrgico y por último dar recomendaciones sobre què tipo de sutura se adapta mejor para la prevención de la adherencia bacteriana. MATERIAL Y MÈTODO: Búsqueda bibliográfica a travès de las bases de datos PubMed, Cochrane y Scielo empleando las palabras clave: surgical sutures, bacterial adherence. Como criterios de inclusión se aceptaron los estudios publicados en los últimos 15 años, in vivo o in vitro en relación con la cirugía oral y con un nivel de evidencia científico superior a 3 según los criterios de evidencia científica. Fueron excluidas todas aquellas publicaciones que no tenían como objeto de estudio las sutura seda, Nylon™, Supramid™, Monocryl™, Vicryl™ o Vicryl Plus™. Tambièn se excluyeron todas aquellas publicaciones que no relacionaban los materiales de sutura a la agregación bacteriana. RESULTADOS: Un total de 9 publicaciones se organizaron en función del tipo de sutura empleada, si eran estudios in vivo o in vitro, el número de pacientes/muestras, tiempo transcurrido hasta la remoción de las suturas, si se realizaron controles, si existió algún tipo de reacción inflamatoria, que tipo de bacterias se agregaron y que material obtuvo mayor agregación. DISCUSIÓN: Los materiales de sutura que mayor acúmulo de placa bacteriana presentan bajo las mismas condiciones de tiempo de exposición a bacterias, son los de tipo multifilamento reabsorbible no tratados con antimicrobianos

OBJECTIVE: To demonstrate the existence of bacterial aggregation to the suture materials that are usually used in dental practice, to verify if aggregation is related to the inflammation that occurs after the surgical act and finally give recommendations on what type of suture is best suited for the prevention of bacterial adhesion. MATERIAL AND METHOD: Bibliographic search through PubMed, Cochrane and Scielo databases using the keywords: surgical sutures, bacterial adherence. Inclusion criteria were accepted studies published in the last 15 years, in vivo or in vitro in relation to oral surgery and with a level of scientific evidence of more than 3 according to the criteria of scientific evidence. All those publications that did not have the suture subject Silk, Nylon™, Supramid™, Monocryl™, Vicryl™ or Vicryl Plus™ were excluded. All publications that did not relate suture materials to bacterial aggregation were also excluded. RESULTS: A total of 9 publications were organized according to the type of suture used, whether they were in vivo or in vitro studies, the number of patients/samples, time elapsed until removal of the sutures, controls if they were performed, any type of inflammatory reaction, which type of bacteria were added and which material obtained greater aggregation. DISCUSSION: The suture materials with the greatest accumulation of bacterial plaque present under the same conditions of exposure to bacteria, are the reabsorbable multifilament type not treated with antimicrobials

Biomechanical comparison of Bunnell, modified Kessler, and Tsuge tendon repair techniques using two suture types.

OBJECTIVE: The aim of this study was to compare the biomechanical properties of modified Kessler, Bunnell and Tsuge techniques in sheep Achilles tendon tear repaired using polyester and polydioxanone sutures which are also compared. METHODS: Sixty sheep Achilles tendons were cut transversely as a substitute for rupture and repaired using modified Kessler, Bunnell and Tsuge techniques with No. 2 braided polyester and monofilament polydioxanone sutures. Specimens were loaded to failure. Four biomechanical parameters - ultimate strength (US), strength to 2 mm gap (S2G), strength to 5 mm gap (S5G) and Young's modulus (YM) - were recorded for statistical analysis. RESULTS: The Tsuge-Polyester group demonstrated the highest results regarding S2G (21.24±4.75 N) (p=.002) and S5G (38.91±7.45 N) (p=.002). According to YM, the Bunnell-Polyester group was the most superior (1929.9±512.28 kilopascal) (p=.009). In the repairs with the polydioxanone suture, Bunnell technique achieved the best purchase with regard to S2G (18.14±6.86 N) (p=.006) and S5G (35.69±13.49 N) (p=.015). The difference between the three repair techniques with the polydioxanone suture was statistically insignificant regarding US (p=.252) and YM (p=.338). Concerning the repairs with the polyester suture, the repair techniques demonstrated no statistically significant difference in terms of US (p=.195), S2G (p=.667), S5G (p=.689) and YM (p=.195). Regarding the mean S2G and S5G values, the polyester suture was significantly superior to the polydioxanone suture in modified Kessler repairs (S2G: p<.001, S5G: p=.001) and Tsuge repairs (S2G: p<.001, S5G: p=.009). The polyester suture was also significantly superior to the polydioxanone suture in the modified Kessler repairs with respect to YM (p=.003). CONCLUSION: This study supports the opinion that Tsuge technique is a promising procedure in Achilles tendon repair (ATR). For Tsuge and modified Kessler repairs, braided polyester suture use appears more advantageous compared to monofilament polydioxanone suture use in biomechanical terms.

A Retrospective Review of Vaginal Cuff Dehiscence: Comparing Absorbable and Nonabsorbable Sutures.

STUDY OBJECTIVE: To compare the rate of spontaneous and complete vaginal cuff dehiscence (VCD) using absorbable versus nonabsorbable sutures for vaginal cuff closure. DESIGN: Retrospective comparative cohort design. SETTING: Freestanding ambulatory surgery center in suburban Maryland. PATIENTS: Women age >18 years old who underwent hysterectomy for benign conditions between October 2013 and April 2018. INTERVENTION: Laparoscopic retroperitoneal hysterectomy was performed by 2 gynecologic surgical specialists. Transvaginal cuff closure was performed using either absorbable Vicryl (polyglactin 910) sutures (n = 881) or nonabsorbable Ethibond (polyester) sutures (n = 574). The nonabsorbable sutures were surgically removed after 90 days. MEASUREMENTS AND MAIN RESULTS: No statistically significant differences in age, race, weight, body mass index, parity, uterine weight, or number of comorbidities were noted between the nonabsorbable and absorbable suture groups. Spontaneous vaginal cuff dehiscence (VCD) occurred in 3 patients (0.52%) in the nonabsorbable group and in 12 patients (1.4%) in the absorbable group (p = .183). Eleven of the 12 cases of VCD in the absorbable group were precipitated by intercourse and occurred within 90 days of surgery. CONCLUSION: Our data suggest that use of a nonabsorbable suture may be an effective approach to prevent spontaneous VCD, but the benefits should be weighed against the inherent risk associated with a second procedure to remove sutures.

Impact of Suture Type on Erosion Rate After Laparoscopic Ventral Mesh Rectopexy: A Case-Matched Study.

BACKGROUND: There has been increasing concern and scrutiny in the use of mesh for certain pelvic organ prolapse procedures. However, mesh erosion was often associated with sites of suture fixation of the mesh to the rectum or vagina. Thus, in response to this finding, we replaced our suture material with absorbable monofilament suture. OBJECTIVE: The purpose of this study was to compare the rates of mesh-related complications after laparoscopic ventral mesh rectopexy, according to the type of suture used in fixation of mesh. DESIGN: This was retrospective cohort study. SETTINGS: This study was performed at a high-volume, tertiary care center. It was conducted using a prospective database including patients who underwent laparoscopic ventral mesh rectopexy over a 7-year period. PATIENTS: A total of 495 cases were included; 296 (60%) laparoscopic ventral mesh rectopexies were performed using a nonabsorbable suture compared with 199 (40%) with an absorbable suture in a case-matched analysis. In addition, 151 cases of laparoscopic ventral mesh rectopexy with nonabsorbable were matched based on age, sex, and time of follow-up, with an equal number of patients using absorbable monofilament suture. MAIN OUTCOMES MEASURES: Primary outcome was symptomatic mesh erosion after rectopexy. Secondary outcomes included other mesh-related complications and/or reoperations. RESULTS: The erosion rate was 2% (6/495) in the nonabsorbable suture group, including 4 erosions into the rectum and 2 into the vagina. There was no erosion in the group with absorbable suture. This difference was maintained after matching: after a median follow-up of 6 (12) months, there was no erosion in the absorbable suture group versus 3.3% erosion (n = 5) in the nonabsorbable suture group (p = 0.03). LIMITATIONS: This study was limited by its retrospective design. CONCLUSIONS: Mesh-related complications are reduced using absorbable sutures compared with nonabsorbable sutures when performing laparoscopic ventral mesh rectopexy with synthetic mesh without an increase in rectopexy failures.

IMPACTO DEL TIPO DE SUTURA EN LA TASA DE EROSIóN DESPUéS DE LA RECTOPEXIA VENTRAL LAPAROSCóPICA CON MALLA: UN ESTUDIO DE CASOS EMPAREJADOS: Ha habido una creciente preocupación y escrutinio en el uso de la malla para ciertos procedimientos de prolapso de órganos pélvicos. Sin embargo, la erosión de la malla a menudo se asoció con sitios de fijación de sutura de la malla al recto o la vagina. Por lo tanto, en respuesta a este hallazgo, reemplazamos nuestro material de sutura con sutura de monofilamento absorbible.Comparar las tasas de complicaciones relacionadas con la malla después de la rectopexia laparoscópica de malla ventral, de acuerdo al tipo de sutura utilizada en la fijación de la malla.Este fue un estudio de cohorte retrospectivo.Este estudio se realizó en un centro de atención de tercer nivel de alto volumen. Se realizó utilizando una base de datos prospectiva que incluía pacientes que se sometieron a una rectopexia de malla ventral laparoscópica durante un período de 7 años.Se incluyeron un total de 495 casos; 296 (60%) rectopexias de malla ventral laparoscópica utilizando una sutura no reabsorbible en comparación con 199 (40%) con una sutura absorbible en un análisis de casos emparejados. Además, 151 casos de rectopexia ventral laparoscópica con malla no absorbible se emparejaron según la edad, el sexo y el tiempo de seguimiento con un número igual de pacientes que usaban sutura de monofilamento absorbible.La medida de resultado primaria fue la erosión sintomática de la malla después de la rectopexia. La medida de resultado secundarias incluyeron otras complicaciones y/o reoperaciones relacionadas con la malla.La tasa de erosión fue del 2% (6/495) en el grupo de sutura no absorbible; 4 erosiones en el recto y 2 en la vagina. No hubo erosión en el grupo con sutura absorbible. Esta diferencia se mantuvo después del emparejamiento: después de una mediana de seguimiento de 6 (12) meses, no hubo erosión en el grupo de sutura absorbible versus 3.3% de erosión (n = 5) en el grupo de sutura no absorbible (p = 0.03).Este estudio estuvo limitado por su diseño retrospectivo.Las complicaciones relacionadas con la malla se reducen utilizando suturas absorbibles en comparación con las suturas no absorbibles cuando se realiza la rectopexia de malla ventral laparoscópica con malla sintética, sin un aumento en los fracasos de rectopexia.

Uso de retractor Alexis en cirugía de tiroides y paratiroides / Use of Alexis retractor in thyroid and parathyroid surgery

En los procedimientos quirúrgicos de tiroides y paratiroides es indispensable una buena exposición de la glándula tiroidea, lo cual se realiza habitualmente mediante suturas de tracción de los colgajos dermoplatismales a los paños del campo operatorio, lo que produce tensión e incluso daños en la piel. El anillo retractor Alexis® mejora la exposición y facilita el acceso a la celda tiroidea de forma estable, protegiendo la piel de lesiones durante la intervención

In thyroid and parathyroid surgical procedures, good visibility of the thyroid gland is essential. This is traditionally achieved by means of traction sutures of the dermo-plastysmal flaps to the drapes of the operative field, producing tension and even damage to the skin. The Alexis® retractor ring improves exposure and facilitates stable access to the thyroid, protecting the skin from injury during the intervention

[A modified implant for upper eyelid ptosis correction in frontalis suspension surgery]. / Primenenie modifitsirovannogo implantata dlia ustraneniia ptoza verkhnego veka podveshivaniem.

AIM: to develop a modified implant to correct ptosis through brow suspension and to evaluate its effectiveness. MATERIAL AND METHODS: The clinical group consisted of 20 patients (29 eyes) aged 23 to 69 years (45±5.3 years on the average) and the comparison group - of 20 patients (33 eyes) aged 19 to 77 years (47±9.5 years on the average). All patients were operated on for severe ptosis of the upper eyelid, which implied stitching their eyelids to the eyebrows. In the main group, an original implant was introduced as suspensory material - a 200 µm thick porous polytetrafluoroethylene tape, length 13 cm, width 6 mm, round staggered perforation pattern, 1.5 mm holes, 3.5 mm pitch. In the comparison group, Mersilene mesh strips were used. The article contains a detailed description of the surgical technique. Checkups were performed at 1, 6, and 12 months. Follow-up periods were up to 4 years (1.7 years on the average) in the main group and up to 7 years (5.1 years on the average) - in the controls. RESULTS: Were evaluated by the width of the palpebral fissure at raised eyebrows, marginal reflex distance (MRD, which is the distance between the center of the pupil and the upper eyelid margin), presence and depth of the upper eyelid crease, and residual lagophthalmos. Examinations held at months 1, 6, and 12 after surgery showed that the results were positive and stable in all cases. Neither signs of recurrence, nor statistically significant differences between the groups were found. CONCLUSION: The use of the original modified implant during frontalis suspension surgery provides high and stable cosmetic result and expands the possibilities of ophthalmic plastic surgery.

Pancreaticojejunostomy after pancreaticoduodenectomy: Suture material and incidence of post-operative pancreatic fistula.

PURPOSE: Pancreatic fistula represents the most important complication in terms of clinical management and costs after pancreaticoduodenectomy. A lot of studies have investigated several techniques in order to reduce pancreatic fistula, but data on the effect of sutures material on pancreatic fistula are not available. The analysis investigated the role of suture material in influencing pancreatic fistula rate and severity. METHODS: Results from 130 consecutive pancreaticoduodenectomy with pancreaticojejunostomy performed between March 2013 and September 2014 were prospectively collected and analyzed. In 65 cases pancreaticojejunostomy was performed with absorbable sutures, in the other 65 cases using non-absorbable sutures (polyester, silk and polybutester). RESULTS: Pancreaticojejunostomy with non-absorbable sutures had the same incidence of pancreatic fistula, but less severe and with less episodes of post-operative bleeding if compared with absorbable sutures. A sub-analysis was carried out comparing polydioxanone with polyester: the latter was associated with a lower pancreatic fistula rate (11.9% vs. 31.7%; p = 0,01) and less severe pancreatic anastomosis dehiscence (grade C - 0% vs. 30%; p = 0.05). Univariate and multivariate analysis confirmed that hard pancreatic texture, pancreatic ductal adenocarcinoma at final histology and the use of polyester for pancreaticojejunostomy were associated with a lower pancreatic fistula rate (p < 0.05). CONCLUSION: Further studies are needed to investigate the effects of pancreatic juice and bile on different sutures and pancreatic tissue response to different materials. However, pancreaticojejunostomy performed with polyester sutures is safe and feasible and is associated to a lower incidence of pancreatic fistula with less severe clinical impact.

A randomized 'N-of-1' single blinded clinical trial of barbed dermal sutures vs. smooth sutures in elective plastic surgery shows differences in scar appearance two-years post-operatively.

BACKGROUND: Barbed sutures have unidirectional circumferential shallow barbs, which distribute tension throughout the wound and close wound securely without the need to tie knots. OBJECTIVES: We compare two different methods of wound closure in elective plastic surgical cases: barbed 3/0 V-Loc™180 suture and smooth 3/0 Maxon™ sutures, both polyglyconate monofilament synthetic absorbable sutures. We assessed the aesthetic long-term results with a minimum two year follow up. METHODS: This is a prospective, randomized controlled study with internal control. A single surgeon performed all cases. Patients who underwent elective operations that involved long wound closure were enrolled in the study. Each patient acted as their own internal control with half their wound being sutured with 3/0 V-Loc™180 barbed suture and the other half with smooth 3/0 Maxon™ deep dermal sutures and then a subcuticular skin closure. In both groups, the superficial fascial system was closed with 1 Vicryl interrupted sutures on both sides. Long-term cosmesis was evaluated using the modified Hollander cosmesis score by review of standardized postoperative photographs by 9 blinded plastic surgeons and specialist registrars. RESULTS: The study reports on 33 female patients. The time taken for wound closure was significantly reduced using the barbed suture (p < 0.001). There was no difference in the complication ratio in either group. Two-year aesthetic outcome was significantly superior when using the barbed suture (p = 0.0075). CONCLUSION: Barbed sutures closure of long wounds is faster and produces a better long-term aesthetic outcome than smooth sutures.

Skin tension related to tension reduction sutures.

The aim of this study was to compare the skin tension of several fascial/subcutaneous tensile reduction sutures. Six upper limbs and 8 lower limbs of 4 fresh cadavers were used. At the deltoid area (10 cm below the palpable acromion) and lateral thigh (midpoint from the palpable greater trochanter to the lateral border of the patella), and within a 3 × 6-cm fusiform area of skin, subcutaneous tissue defects were created. At the midpoint of the defect, a no. 5 silk suture was passed through the dermis at a 5-mm margin of the defect, and the defect was approximated. The initial tension to approximate the margins was measured using a tensiometer.The tension needed to approximate skin without any tension reduction suture (S) was 6.5 ± 4.6 N (Newton). The tensions needed to approximate superficial fascia (SF) and deep fascia (DF) were 7.8 ± 3.4 N and 10.3 ± 5.1 N, respectively. The tension needed to approximate the skin after approximating the SF was 4.1 ± 3.4 N. The tension needed to approximate the skin after approximating the DF was 4.9 ± 4.0 N. The tension reduction effect of approximating the SF was 38.8 ± 16.4% (2.4 ± 1.5 N, P = 0.000 [ANOVA, Scheffé]). The tension reduction effect of approximating the DF was 25.2% ± 21.9% (1.5 ± 1.4 N, P = 0.001 [ANOVA, Scheffé]). The reason for this is thought to be that the SF is located closely to the skin unlike the DF. The results of this study might be a basis for tension reduction sutures.

Sutures, needles, and tissue adhesives: a review for dermatologic surgery.

BACKGROUND: Dermatologic surgery generally requires the removal of offending or excessive tissue followed by repair of the resultant defect. The functional and cosmetic outcome is increasingly important as patients' expectations grow and physicians become increasingly aware of surgical materials and techniques that enable them to repair defects in a functionally and cosmetically appealing manner. OBJECTIVE: To perform an updated and thorough review of the literature regarding sutures, surgical tape, tissue adhesives and stitching techniques. MATERIALS AND METHODS: A comprehensive literature review was conducted on-line via multiple search engines and sites using the keywords suture, suture techniques, suturing techniques, surgical techniques, surgical tapes, surgical adhesives, and tissue adhesives. RESULTS: There are numerous articles on sutures, surgical tape, and tissue adhesives, but there are no current articles that review them together in a comprehensive manner and combine the review with a discussion of stitching techniques. CONCLUSION: Suture choice and surgical and stitching techniques may be guided by the TAFT concept of wound closure that recognizes the main function of suture and closure devices: Tension relief; Apposition enhancement; and surface Finishing Touches. The dermatologist's goal is to create functionally and aesthetically pleasing scars for optimal patient satisfaction, which is of ultimate importance considering that the scars patients receive leave a lasting impression of their dermatology experience.

Popularity of suture materials among residents and faculty members of a postdoctoral periodontology program.

AIM: The aim of the present study was to determine the favoritism of suture materials among a group of clinicians at a teaching institution. METHODS: The surveys included 11 absorbable and nine non-absorbable sutures. The surveyor was asked to select his or her suture preferences when it comes to using it in 13 different, commonly-performed surgical procedures. RESULTS: The surveys showed overall preferences for non-absorbable versus absorbable sutures. Chromic Gut with a 4-0 diameter thread reverse cutting FS2 needle was the most favored suture. For periodontal bone grafts and hard tissue ridge augmentation, polytetrafluoroethylene with a 4-0 thread and FS2 needle was preferred. For autogenous gingival grafts, gingival allografts, connective tissue grafts, frenectomy and frenoplasty, Chromic Gut with 5-0 diameter thread reverse cutting P3 needle was favored. For extraction socket preservation, soft tissue canine exposure, ridge augmentation, and dental implants, Chromic Gut with 4-0 diameter thread reverse cutting FS2 needle was preferred, and for sinus augmentation, Vicryl with a 4-0 diameter thread reverse cutting FS2 needle was favored. CONCLUSION: Absorbable sutures were preferred in the majority of periodontal procedures; however, non-absorbable sutures were favored in procedures that required longer healing or better stability of the flap edges in cases of periodontal and ridge augmentation.

Suture type and ultrasound-indicated cerclage efficacy.

OBJECTIVE: To assess whether type of suture material affects cerclage efficacy for preterm birth (PTB) prevention. METHODS: Secondary analysis of a multicenter trial of ultrasound-indicated cerclage for short cervical length (CL), in which women with prior spontaneous PTB at 16-33 6/7 weeks, a singleton gestation and CL < 25 mm between 16-22 6/7 weeks, were randomized to McDonald cerclage or no cerclage. Outcomes of women who underwent cerclage were analyzed by type of suture material, comparing polyester braided thread (Mersilene™ or Ethibond™) to Mersilene tape™. Primary outcome was PTB < 35 weeks. RESULTS: 138 women underwent McDonald cerclage: 84 (61%) received polyester braided thread and 46 (33%) Mersilene tape™. Eight (6%) received monofilament suture and were excluded from analysis. Rates of PTB < 35 weeks were similar, 35% for polyester braided thread vs 24% for Mersilene tape™ (p = .24). Birth gestational age was also similar among the 2 groups (p = .18). CONCLUSION: Type of suture material may not affect ultrasound-indicated cerclage efficacy in high-risk women with short CL, but further study is needed. Polyester braided thread (Mersilene™ or Ethibond™) and polyester braided Mersilene tape™ seem to have similar efficacy.
