Aim: The aim of this article was to compare the tissue contraction after the surgical repair of unilateral cleft lip side to noncleft lip side. Materials and Methods: Forty patients with unilateral cleft lip only were used as subjects. They were divided into two groups based on gender (20 males and 20 females). Measurements of soft-tissue landmarks of cleft side and noncleft side were compared after surgical repair of the lip to check for soft-tissue contractions. A vernier caliper was used to measure the linear measurements, and all the measurements were measured directly on the patients' lips. Results: When gender comparison was done, it was found to be significant only for oral commissure to the peak of Cupid's bow for both cleft and noncleft sides (P < 0.05). When comparison between the two sides (left and right) was done, a significant difference was observed only for subalar to peak of Cupid's bow measurement which was found to be significantly larger at noncleft as compared to cleft side in overall assessment (P = 0.005) and in females (P = 0.046); however, this difference was not statistically significant when evaluated for males alone (P = 0.060). Conclusion: Marked soft-tissue contraction was seen after surgical repair of the unilateral cleft lip, more was seen in females. This indicates that adequate planning and accurate surgical techniques and measurements should be taken while approximating the two lip flaps both in vertical and in horizontal direction before planning the surgery to get the best esthetic result for the patients.

| Introduction|| |
Patients with cleft lip or palate require a multidisciplinary team that focuses on the patients' form, function, and physiological and psychosocial development. Unilateral cleft lip scar is a common phenomenon occurring due to either tension in the repair or improper suturing of the orbicularis muscles. Trauma and infection may be rarer causes. Scarring on the repair side depends on the three factors: intrinsic strain, which depends on the tightness of the suturing; extrinsic strain, which is the tension with which the tissues are brought together; and the inherent reaction of the individual to surgical trauma.,,, The surgeon has control over the first two factors, but not over the third. In the early period following the repair, most children exhibit a scar contracture with a pulled up Cupid's bow and a vermillion notch on the cleft side. Vermillion notching is a discontinuity in the free border of the vermillion. This may be central (“whistle deformity”) or seen laterally along the line of the scar, the latter is more common in unilateral lips.
Cheiloplasty for cleft lip defects often results in severe scar formation, which, in turn, markedly affects facial esthetics. Furthermore, it has considerable influence on the anterior occlusion, such as lingual inclination of the maxillary anterior teeth in unilateral cleft lip patients with or without cleft palate., The assessment of scar tissue distribution and soft-tissue contraction postsurgery in the repaired lip is of great importance for orthodontic diagnosis, treatment planning, and prognosis. The severity of the primary deformity is generally proportional to the difficulty of surgical reconstruction and subsequently with scar formation in the palate and lip.,, Furthermore, cleft lip/palate is known to be a key factor in maxillary growth retardation both in the vertical and horizontal directions. However, little is known about the changes seen in the soft-tissue after the surgery following lip repair. The aim of this anthropometric study was to compare the tissue contraction after the surgical repair of unilateral cleft lip side to noncleft lip side.

This study was conducted at Vivekananda Polyclinic and Institute of Medical Sciences, Lucknow, India. Forty patients with unilateral cleft lip were taken and were divided into two groups based on gender (20 males and 20 females). Primary cleft lip repair was carried out between the age of 3 and 6 months (mean age 4.3 months). The study was approved by the Institutional Ethical Committee of Swami Vivekanand Hospital and Research Centre, Lucknow, India. Informed consent was obtained from each subject's parents after appropriate explanation about the surgery involved and the study.
Measurements of soft-tissue landmarks of cleft side and noncleft side were compared after surgical repair of the lip to check for soft-tissue contractions. All of the anthropometric lip measurements were taken using a vernier caliper. The vertical height and transverse length measurements of both the cleft and noncleft sides of the lips were recorded to the nearest 0.5 mm. The anthropometric points used for the measurement were as follows:
- Right vermillion border – it is the edge (border) of the red (vermilion) of the lip on the right side
- Peak of Cupids bow right – highest point on the double curve of the human upper lip right side
- Base of columella left – lower most point at the base of the columella on left side
- Base of columella right – lower most point at the base of the columella on right side
- Junction between dry and wet lip – the line demarcating the dry vermillion from the wet vermillion
- Left vermillion border – it is the edge (border) of the red (vermilion) of the lip on the left side
- Base of alar left – lower most point at the base of the nostril medially of left side
- Subalar base left – lowermost point of the nostril laterally of left side
- Lateral alar base left – most lateral point at the base of the nostril of left side.
Medial lip heights were measured from the midline of the labiocolumellar groove (subnasale) to the peaks of the cupid's bow. Lateral lip height of the noncleft side was measured from the lowest point of the alar base to the peak of the cupid's bow. Height of the cleft lip side was measured from the lowest point of the alar base (subalar) to the proposed peak of cupid's bow. The proposed peak of cupid's bow was the vermilion cutaneous junction where the cutaneous roll and the vermilion mucosal junction (red line) begin to converge medially [Figure 1]. The lateral lip transverse length of noncleft side was measured from the oral commissure to the peak of cupid's bow. The lateral lip transverse length of the cleft side was measured from the oral commissure to the proposed peak of cupids bow at Noordhoff's point.,, Noordhoff's point can be seen along the lateral lip where the vermillion height is at its greatest and the white roll is well formed. This becomes less distinct as we go toward the cleft side.
A master file was created with all the data, and it was statistically analyzed using the Statistical Package for the Social Sciences software (version 17) (SPSS Inc. Released 2008. Chicago, IL, USA). The data were subjected to descriptive analysis for mean, standard deviation, and 95% confidence interval. P < 0.05 was considered statistically significant association. For comparison of gender groups, independent samples t-test was performed. Paired t- test was used for comparison between cleft and noncleft side. To identify the errors associated with the linear measurements, all the measurements were repeated 8 weeks postsurgery. A paired sample t-test was applied to the first and second measurements, and the differences between measurements were insignificant.
| Results|| |
When gender difference was compared, it was found to be significant only for oral commissure to the peak of cupid's bow for both cleft as well as noncleft sides (P < 0.05) [Table 1]. Between two sides, a significant difference was observed only for subalar to peak of cupid's bow measurement which was found to be significantly larger at noncleft as compared to cleft side in overall assessment (P = 0.005) and in females (P = 0.046); however, this difference was not significant statistically when evaluated for males alone (P = 0.060). All the measurements are shown in [Graph 1].
| Discussion|| |
The patients who were included in this study were inhabitants of a particular geographic region of India (northern part of India). Their ethnicity was Asian Indian. There are several factors that influence the optimum timing for closure of a cleft lip.,,, In young infants, it is practically impossible to distinguish between the individual muscle fiber bundles which due to lack of function, are underdeveloped, weak and unable to adequately support sutures.,, It is therefore advised to wait until the end of the 4th month for surgery. By this time, the labial musculature has developed significantly as a result of both growth and function, the function imparted by sucking, crying, and other facial activity. Early reconstruction of the lip further reduces forward growth of the smaller fragment in unilateral clefts, which results in retrusion of the dentoalveolar segment and underdevelopment of the premaxilla., After cleft lip surgery, the ideal line of repair should have the following features:,
- Ascends from cleft side of cupid's bow
- Mirrors the noncleft side philtrum column
- Reach base of the nose
- Continue superolaterally
- Border lip-columellar crease which ascends to the nostril still.
This study attempts to compare the soft-tissue changes after surgery in unilateral cleft lip patients. The results of our study show differences in the measurements of the soft-tissue landmarks involving the lip structures between male and female groups and left and right sides. When gender difference was compared, it was found to be significant only for oral commissure to the peak of Cupid's bow for both cleft and noncleft sides. Singh et al. did a 3-dimensional (3D) study of the facial morphology after surgical repair of unilateral cleft lip after nasoalveolar molding. They found that 3D facial morphology was virtually indistinguishable from the noncleft mean and clinically the apparent improvement in the facial soft-tissues may be the masked dysmorphic skeletal growth. Males at birth are generally larger in size than females. Rate of retraction of soft-tissue in females must have been higher in females than in males. There was no significant difference between the values before the surgery and on the contralateral side. Hence, it can be stated that the soft-tissue retraction after the surgery was higher in females. Holst et al. found that patients with cleft lip who were treated with a standardized treatment concept had adequate craniofacial jaw relationships. Despite a measured skeletal Class I in both male and female patients with cleft lip and palate regardless of cleft type, there was a slight tendency toward a skeletal Class III. This shows that due to deficient maxilla, the soft-tissue over this region may not have developed fully. The maxillary bone support would be inadequate for the proper development of the lip.
When both the sides were compared (cleft and noncleft side), a significant difference was observed only for subalar to peak of cupid's bow measurement which was found to be significantly larger at noncleft as compared to cleft side in overall assessment and in females. In this result, again, we can see that there has been higher soft-tissue contraction after the surgery in females. This should be kept in mind while planning for cleft lip surgeries in females. Liao and Mars concluded that adverse effects of clefts on the growth of the maxilla in patients with unilateral cleft lip and palate (UCLP) are restricted to the basal maxilla in size. The reduced growth in unoperated patients with UCLP might be primarily attributed to intrinsic effects and secondarily to functional effects. Further studies are required to find the exact effect of the intrinsic and the functional factors on the growth of the soft-tissue following cleft lip surgery.
| Conclusion|| |
Marked soft-tissue contraction was seen after surgical repair of the unilateral cleft lip, more was seen in females. This indicates that adequate planning and accurate surgical techniques and measurements should be taken while approximating the two lip flaps both in vertical and in horizontal direction before planning the surgery to get the best esthetic result for the patients.
