Protocol summary

Study aim
evaluation and comparison of the amount of the mucosal scar following application of Vicryl Rapide and Vicryl suture materials in LeFort I osteotomy
Design
A triple-blinded clinical trial with parallel and split-mouth design, self-controlled and randomized with the study sample size of 26 patients. for randomization purposes, online computer-based software (www.randomization.com) will be used.
Settings and conduct
26 patients undergoing LeFort I osteotomy in Alzahra and Kashani teaching hospitals will be included. after performing the osteotomy, suturing the incision line will be performed using Vicryl Rapide and Vicryl suture materials on the right and left sides based on the randomized order in the sealed envelop for each patient.after 4 months, evaluation the scar tissue using the mucosal scarring index will be performed by three OMF surgeons. patients, outcome assessors, investigator, and data analyzer will be blinded by just access to the codes "A" and "B" allocated to the suture materials.
Participants/Inclusion and exclusion criteria
all patients undergoing LeFort I osteotomy for correction of their skeletal deformity are included in this study. any factor causing impaired wound healing and unusual scar formation excludes the patient from the study.
Intervention groups
after performing LeFort I osteotomy and based on the randomized order, the right side of the incision in the maxillary vestibular area will be sutured using one suture material (Vicryl Rapide or Vicryl) and the left side will be closed using another suture material (Vicryl or Vicryl Rapide). after 4 months the mucosal scar will be evaluated by three oral and maxillofacial surgeons using the mucosal scarring index. due to the split-mouth design, patients are self-control and there would not be any separate control group.
Main outcome variables
the mean score of the mucosal scarring index; type of the suture material

Inclusion/Exclusion criteria
Inclusion criteria:
patients undergoing Le-fort I osteotomy for correction of skeletal deformity
Exclusion criteria:
age less than 18 or more than 40 pre-existing scar in vestibular area or history of surgery in maxillary vestibule any systemic and chronic disease which can interfere with wound healing process (i.e. diabetes, kidney and liver diseases) long-term corticosteroid or antibiotic therapy, or immunosuppressor drugs (specially in the last 6 month) congenital or acquired compromising immune system dehydration and malnutrition and associated neural defects (especially vitamin C and zinc deficiency) history of radiotherapy and using cytotoxic drugs tobacco use and alcoholism Fitzpatrick skin classification types I, IV, V, VI Maxillary advancement more than 6 mm history of allergic reaction (known or suspected) to suture materials

Sample size
Target sample size: 26
More than 1 sample in each individual
Number of samples in each individual: 2
In each patient, the right half of the incision (from the maxillary first molar to the mid-line) will be sutured with one suture material (vicryl or vicryl rapide based on a randomization plan) and the left half with the other suture material.
Randomization (investigator's opinion)
Randomized
Randomization description
simple randomization using online computer-based software (http://www.randomization.com) leading to a randomized plan in which the first suture will be used in the right side and the second suture on the left side of the surgery. unit of randomization is individual and by using a sealed envelop for each patient consisting of the order of suturing and suture materials, the right half of the incision (from the maxillary first molar to the mid-line) will be sutured with one suture material (vicryl or vicryl rapide based on randomization plan) and the left half with the other suture material.
Blinding (investigator's opinion)
Triple blinded
Blinding description
Patient: patients are not aware of the exact location of the suture materials. Outcome assessor: assessors are not aware of the exact location of the suture materials during the examination of the scar tissue. Investigator: The researcher will not be aware of the exact location of the suture materials and they will be only informed by the surgeons' registrations in the patients' form using "A" and "B" codes for suture materials. Data analyzer: analyzer won't be aware of the exact location of the suture materials and data is given to him/her coded as "A" and "B".
Placebo
Not used
Assignment
Parallel
Other design features
Split-mouth design: the right half of the incision (from the maxillary first molar to the mid-line) will be sutured with one suture material (vicryl or vicryl rapide based on randomization plan) and the left side with the other suture material.

Intervention groups

1

Description
Intervention group 1: Considering an ID number from 1 to 26 for each patient, randomization is done using online computer-based software (http://www.randomization.com). The randomization plan is used as follows: "the first suture name is placed on the right side while the second one on the left side of the incision line". Le-fort I Osteotomy is done using a V-shaped incision in vestibular mucosa of the maxilla; 5 mm superior to the mucogingival junction from maxillary right first molar to the maxillary left first molar. after osteotomy and before suturing the incision line, alar base cinch technique using 3-0 nylon (Ethicon Inc., Johnson and Johnson Company, Somerville, New Jersey) suture material for preventing the widening of the base of the nose. due to the split-mouth design, the sealed envelop related to the patient's ID number is peeled open and the right side of the incision line from the maxillary right first molar to the mid-line is sutured with vicryl (Ethicon Inc., Johnson and Johnson Company, Somerville, New Jersey) or vicryl rapide (Ethicon Inc., Johnson and Johnson Company, Somerville, New Jersey) suture as mentioned in the randomization plan by continuous lock technique and in a tension-free manner.
