Objective To supply quantitative information about the facial soft tissues of adult operated patients with cleft lip and palate (CLP). Design, Setting, and Patients The three-dimensional coordinates of soft tissue facial landmarks were obtained using an electromagnetic digitizer in 18 Caucasian patients with CLP (11 males and 7 females aged 19 to 27 years) and 162 healthy controls (73 females and 89 males aged 18 to 30 years). From the landmarks, 15 facial dimensions and two angles were calculated. Data were compared with those collected in healthy individuals by computing z-scores. Two summary anthropometric measurements for quantifying craniofacial variations were assessed in both the patients and reference subjects: the mean z-score (an index of overall facial size), and its SD, called the craniofacial variability index (an index of facial harmony). Results In treated patients with CLP, facial size was somewhat smaller than in normal individuals, but in all occasions the mean z-score fell inside the normal interval (mean ± 2 SD). Almost all patients had a craniofacial variability index larger than the normal interval, indicating a global disharmonious appearance. Overall, in patients pronasale, subnasale, and pogonion were more posterior, the nose was shorter and larger, the face was narrower, and the soft tissue profile and upper lip were flatter than in the reference population. Conclusions The facial soft tissue structures of adult operated patients with CLP differed from those of normal controls of the same age, sex, and ethnic group. In this patient group, surgical corrections of CLP failed to provide a completely harmonious appearance, even if the deviations from the reference were limited. Further analyses of larger groups of patients are needed.

Maxillary Deficiency

During the last 15 years, cleft lip and palate (CLP) patients with maxillary deficiency in the care of the Bergen CLP team have undergone an interceptive orthopedic treatment phase during the deciduous and mixed dentition period. The present study includes 68 patients who received maxillary transverse expansion by use of a modified quad-helix appliance and 98 cases given maxillary protraction by a facial mask. All cases were treated until an acceptable normal occlusion was attained. Lateral cephalograms were taken immediately before and after the active treatment periods. Sagittal changes of the soft-tissue profile during transverse expansion and protraction were analyzed separately for unilateral complete cleft lip and palate (UCLP) patients and bilateral complete cleft lip and palate (BCLP) patients. The soft-tissue profiles of the groups were compared to growth changes of noncleft age-matched children (NORM group). During the short period of maxillary transverse expansion (mean period, 3.5 months) no significant change of the soft-tissue profile was found, except in the protrusion of the lower lip in the BCLP group. During the period of maxillary protraction (mean periods, 12 months in the UCLP group and 15 months in the BCLP group) the soft-tissue profile improved significantly by reducing the characteristic tendency towards a concave profile in CLP patients with maxillary deficiency. Significant Increases of the sagittal maxillomandlbular lip relation (angle SS-N-SM: mean Increase, 2.5 degrees) and the Holdaway-angle (H-angle: mean increase, 3.0 degrees) were found to be similar in the UCLP and BCLP groups. However, the use of different reference lines for evaluation of treatment effects upon the soft-tissue profile resulted in conflicting findings suggesting that anteriorly situated reference lines are more suitable for the evaluation of CLP patients. Thus, the esthetic line (E.line) indicated a favorable position of the lips after treatment; the subspinale-pogonlon line (ss.pg) revealed an Improved soft-tissue profile; the soft-tissue-facial line (N.PG) showed a retruded nose and upper lip; whereas basal references such as the nasion-sella line (NSL) and the occlusal-line perpendicular (OLP) mainly showed major differences between the CLP groups and the NORM groups.

The purpose of this study is to measure the soft tissue profile changes before and after treatment of dento-alveolar bimaxillary protrusion cases which had orthodontic treatment including extraction of upper and lower first premolars. Iori's soft tissue analysis used in this study and cephalometric analysis on 14 patients wich fulfilled sample criteria was performed. Four angular and two linear measurements were done manually utilizing protractor. Statistical analysis was paired t-test. The result showed significant changes in soft tissue after the treatment.

Retrospective Investigation

Objective. This study aimed to evaluate cephalometric soft tissue characteristics in individuals with unilateral complete cleft lip and palate (UCCLP) both with and without missing teeth. Design. A retrospective investigation of patient records, who are being treated at the cleft lip and palate (CLP) clinics at the College of Dentistry. Ninety-six consecutive records of nonsyndromic UCCLP subjects were recruited (33 subjects without missing teeth and 63 subjects with missing teeth). Linear and angular soft tissue measurements obtained from lateral cephalometric radiographs were evaluated and compared among the studied samples. Results. Lower lip was significantly retruded and shorter (p=0.037), p=0.015, respectively; in addition to the fact that shallower mentolabial sulcus (p=0.05) was found in the subjects with missing teeth, the rest of the soft tissue was not significantly different between the two groups. Conclusion. In subjects with a UCCLP anomaly, missing teeth have an effect on lower lip position and length, which influenced the mentolabial sulcus. Lower lip position and length differ between cleft patients who present with either multiple missing teeth or with no missing teeth, and this needs to be considered during orthodontic treatment planning and surgical management for the cleft defect.

General Care

The literature concerning orthodontic treatment of malocclusion associated with cleft lip and palate has been reviewed. The aims of treatment and a number of skeletal, soft tissue, dento-alveolar and general care factors which influence treatment planning are discussed. The effect of early orthopaedic treatment, examined solely on the grounds of eventual arch form in the deciduous dentition, reveals a prophylactic benefit in some, but not all reports. There would appear to be little benefit in carrying out orthodontic treatment in the deciduous dentition but it is suggested that the progressive development of severe overclosure during the mixed dentition phase should be intercepted using simple appliances. The most important phase of treatment follows eruption of the permanent dentition and appliances are described which are capable of substantial radial and vertical corrections in preparation for a permanent prosthesis.

Experimental Group

This study investigated the effect of a standard surgical technique for the repair of unilateral cleft lip and palate by one surgeon. Limitations were set by the numbers available for investigation, however comparison was made between a small group of such treated cases and a group of normal children. The method of assessment was based on a cephalometric analysis with extrapolation to the integumental profile. A number of different points were proposed for attributes of the soft tissue profile. The base reference line used was Sella-Nasion, points A and B and the extrapolations to the overlying soft tissue. Facial convexity was proposed as an angle subtended at the tip of the nose by the chin point and soft tissue nasion. Facial height was measured as a ratio between upper and lower facial dimensions. Lip tissue thickness was a direct measurement. The result of this study supported some findings in other studies. The point of most interest was the small amount of difference between the experimental group and the group used for comparison. Both maxillary and mandibular retrusion was noted and there appeared slight flattening of the soft tissue profile. However, no differences were noted in lip thickness and facial height.
