The Effects of Palatal Pre-sutures in Connective Tıssue Graft Surgery
The Effects of Palatal Pre-sutures on Hemostasis and Patient Comfort in Connective Tıssue Graft Surgery
Connective tissue graft operation is one of the most frequently performed surgical procedures to increase the width of the attached gingiva and to treat gingival recessions. The most preferred donor site during this operation is the palatal mucosa.Reported postoperative complications are usually related to the donor site. Problems such as prolongation of bleeding time, delay in wound healing and severe pain in the palatal region where the graft is taken are frequently encountered. Bleeding control in the palatal donor area is very important for patient comfort. Additional measures may be required to control bleeding, such as sutures with or without hemostatic agents, or acrylic, plastic palatal stents and periodontal pastes prepared before the operation. Suturing the Greater Palatine Artery (GPA) or terminal vessel branches has been shown to be an effective method to control palatal bleeding.
Therefore the aim of this study is to evaluate the effectiveness of the pre-suture method applied in the palatal region before the connective tissue graft is taken in reducing hemostasis.Pre-suture method can increase the operator's field of vision and operational comfort. Patient-reported outcomes such as the amount of pain and bleeding in the palatal donor area during and after surgery, painkiller intake, number of days of discomfort, satisfaction, quality of life, and willingness to be treated will be evaluated.
In addition, it will be evaluated whether this suture technique affects the healing of the half-thickness flap in the palatal region after obtaining a connective tissue graft with a single incision method.

Description détaillée
Various methods have been described to manage bleeding and/or promote healing of the palatal donor site.These techniques include sutures with or without hemostatic agents, or the use of materials such as acrylic or plastic palatal stents, periodontal seals, and platelet-rich fibrin (PRF) prepared before the operation. The use of an additional hemostatic agent often requires additional surgical time and expense, and most of the techniques described in the literature for the management of palatal hemorrhage are used to control bleeding after it has occurred. GPA and/or suturing of terminal vessel branches is a popular and effective technique to control palatal bleeding.Recently, a detailed protocol for a Greater Palatine Compression Suture (GPCS) has been presented and proposed as a predictable method for controlling bleeding when this suture is applied preoperatively at the palatal donor site. This protocol is based on the estimated location of the greater palatal foramen and vascular bundle and has proven to be efficient in controlling palatal bleeding. The recommended protocol for GPCS is as follows:
- The midpalatal line is defined.
- An imaginary line is joined to the midpalatal line from the midline of the first and second maxillary molars (point X).
- Another point (Point A) is defined along the X line at a distance of 20 mm from the midpalatal line. (Y point)
- The needle is passed through point A along its curve, and the exit point (point B) of the needle should be approximately 10 mm medial and approximately 5 mm anterior to point A. 1/2 diameter, triangular body, 3-0 braided silk sutures recommended in this protocol were used. The effectiveness of GPCS on palatal hemostasis before obtaining a free gingival graft was also evaluated previously. Reduced palatal bleeding is a valuable clinical benefit in terms of reduced perioperative morbidity, better visibility for the operator, reduced need for hemostatic agents, and operation time.
In addition, the availability of such a technique can be reassuring to the operator when removing autogenous grafts and may be of additional importance in patients prone to bleeding. One of the primary results in our study was the amount of perioperative bleeding. Methods of measuring perioperative blood loss include direct volumetric estimation, weighing blood gauze pads, using various formulas based on hematocrit values, and visual estimation. In our study, bloody gauze pads will be measured with precision scales and the amount of bleeding in the palate will be directly measured during the operation.
In our study, it is aimed to evaluate whether the BPKS technique has any effect on the healing of the half-thickness flap in the donor area when applied in connective tissue graft procedures obtained with the single incision method.
Evaluation of donor site wound healing with anamnesis and index records will be performed by a blinded investigator who did not perform the operation (B.K.).
Initial periodontal treatments will be performed for each patient participating in the study before surgical procedures. Oral hygiene, scaling, root planing and occlusal adjustments will be carried out when necessary. Connective tissue graft will be harvested with a single incision method. Surgical procedures will be performed by a single investigator (M.Z.).
At the beginning of the operation, 0.5 mL of 2% lidocaine anesthesia containing 1:200,000 adrenaline will be administered to the palatal donor area to both the control and test groups, from the points corresponding to the canine and the first molar. In the test group, GPCS (Silk, 4-0, 18 mm, 3/8 sharp needle) will be placed before the incision in the palatal region. Then, connective tissue graft will be taken with a single incision technique using a 15-C scalpel in both groups. The thickness of the connective tissue graft to be taken in our study will be 1.5-2 mm, and its dimensions will be 8X8 mm as standard. Then, the half-thickness flap in the palatal region will be closed with a continuous locked suture (Trofilen, 5/0, 16 mm, 3/8 sharp needle). The connective tissue graft will be sutured to the recipient area with 6-0 polyglactin sutures (Pegalak rapid, 13 mm, 3/8 sharp needle) and the flap is shifted coronally (Trofilen, 5/0, 16 mm, 3/8 sharp needle) will be closed with. Measurement of blood loss will be carried out as described above.
There is no study that applies the BPKS technique during the connective tissue graft operation. In addition, patient-reported outcome measures such as painkiller intake, number of days of discomfort, satisfaction, quality of life, and willingness to be treated again, as well as the amount of pain and bleeding of the palatal donor site during and after surgery, were not examined.
The operation period will be started after the incision and will be terminated when the operation is completed. For postoperative care, the patient will be prescribed a mouthwash containing 0.12% chlorhexidine digluconate to be used twice a day for 3 weeks. In addition, analgesic (Flurbiprofen 100 mg film tablet) will be prescribed to be used when they feel pain. After the operation, patients will be asked not to brush the operation area for 2 weeks and patients will be warned to avoid hard chewing. Brushing with a soft brush will be required in the 3rd postoperative week. The suture in the donor area will be removed in the 1st week, and the suture in the recipient area will be removed in the 2nd week postoperatively. GPCS will be taken 1 week after the operation.
Patients will be called for controls on the 3rd day, 1st and 2nd weeks, 1st, 3rd and 6th months after the operation and their measurements will be recorded. The scales evaluated by the patient will be given to the patient after the operation and will be collected when the study is finished. The records that the physician should take after the surgery will always be recorded by a single researcher. The investigator who took the records will not know the surgical technique applied.

Measuring the Amount of Intra-operative Bleeding with a Precision Balance
Délai: During surgery
|
In our study, the amount of blood lost will be estimated by using the gauze weight method, which is a method of directly estimating blood loss.
All measurements will be made on a 1 g precision digital balance.
Sterile gauze swabs will be weighed dry before the operation.
The gauze pads that will be used later will be moistened with 10 mL of sterile 0.9 g/L saline solution before starting the procedure and the weight will be measured again.
The time from the removal of the connective tissue graft to the end of the operation will be measured and the pre-moistened gauze pads will be used on the palate during this period and will be stored separately and their weight will be measured immediately after the operation is over.
In this method, aspiration in the palatal region should be avoided to minimize errors in blood loss measurement.
