This study was designed to help to be given esthetics in construction of denture and prosthodontic rehabilitation of anterior tooth region. The author took the facial straight photograph of 100 old aged people(male 50, female 50) above 55 years of age, who have natural teeth in anterior tooth region, in a resting and a smiling position. And the author measured and analyzed the lip shape, the relation between the lip and the teeth and the change of lip length and height when they were smiling. The results of this study were as follows : 1. In the shape of the upper lip, when the upper lip curved downward, it was 53%, straight was 28% and curved upward was 9%. 2. In the relation between the upper lip and the teeth, average smile was 53% , high smile was 26% and low smile was 21%. 3. In the parallel relation between the lower lip and maxillary anterior incisal curvature, the group of straight was 54%, the group of parallel was 40% and the group of reverse was 6%. 4. In the relationship between maxillary anterior incisor and lower lip, the group of not-touching was 92%, the group of touching was 5% and the group of the maxillary anterior incisor were slightly covered by the lower lip was 3%. 5. In the teeth displayed in a smile, displayed to second premolar was 50%, displayed to first molar was 34%, displayed to first premolar was 12%, and displayed to canine and second molar were 2%. 6. At smiling, the width of the mouth was 0.94 times of the interpupillary distance and 0.45 times of the full face width. 7. At smiling, the length of the upper lip was 0.73 times and lower lip was 0.98 times of the length in a resting postion and the width of the mouth corner was 1.19 times of the resting position.

Even though it is generalized to perform synchronous lip and nasal correction, there are some cases in need of secondary correction of cleft lip nose deformity. In these procedures, the lengthening of columella plays an important role. We performed eighteen cases of the secondary cleft lip nose deformity correction using two different methods from 1997 to 2003. The central lip flap was used in eight patients and V-Y advancement flap in ten patients. Additional procedures including reverse U-incision, interdomal fixation sutures and suspension sutures were used for correction of combined deformity. Silastic nasal retainers were kept in all patients for 6 months. Both of central lip flap and V-Y advancement flap seems to be a good technique for lengthening columellar soft tissue. But new columella after V-Y advancement flap appeared to be too narrow and a bit unnatural looking and central lip flap left additional scar on the upper lip although it was conspicuous. We think that central lip flap is a better technique in a case with wide philtrum and narrow columella and V-Y advancement flap can be another choice in a columella with sufficient width.

In spite of all fine methods developed for treating cleft lip, a certain percentage of cases might still need secondary correction. Generally, secondary revision of cleft lip is much difficult to produce esthetic outcome, because the cleft lip scar gives a variable symmetrical and anatomic defect that may not be possible to make inconspicuous of this scar and rebuild good esthetics. In this case report, a five year-old girl was underwent secondary cleft lip repair using straight line technique to correct unfavorable postoperative scar, peaking of Cupid's bow, notching of vermillion and shortened lip on cleft side with simultaneous repairing cleft palatal fistula. After operation, the secondary deformity was much improved, but, long term follow up is needed to evaluate the additional postoperative deformity might be happen during growth.

Historically, various techniques to correct the deformity of lip and nose in functional and esthetic ways were developed and applied in dealing the patients with cleft lip. When treating the patients with unilateral cleft lip, many surgeons adopt the rotation-advancement method originally developed by Millard, or the triangular flap technique developed by Tennison, Randall or the modifications of these techniques. Among these, triangular flap technique has its advantage in designing the flap using the patient's anatomic landmarks. It enables less skillful operator to perform this technique relatively easily and produce reasonable results. In this report we present 8 cases of unilateral complete cleft lip and 3 casesof unilateral incomplete cleft lip. They all underwent primary cheiloplasty based on triangular flap technique, and functional, esthetic outcomes were favorable.

Vomer flap is used to repair anterior hard palate in complete cleft lip and palate patients. As the midline structure located in between the two cleft segments of hard palate, the vomer flap is very useful because of its vicinity to cleft site and their ease of execution when it is done with primary cheiloplasty simultaneously. In addition, the quality of tissue is very similar to that of the nasal mucosa with good vascularity. In cases of simultaneous repair of cleft lip with anterior palate using vomer flap, the hard palate can be repaired at the same time with primary cheiloplasty which is earlier period than other techniques. With simultaneous close of cleft lip and cleft hard palate by vomer flap, subsequent palatoplasty does not require wide dissection, and consequently chance of oronasal fistula formation will be minimized. Additionally, surgical time will be reduced and, the harmful effects on mid-facial growth will be diminished. In this article, we will introduce the comprehensive vomer flap technique with primary lip closure and review the comparative studies of the outcome of simultaneous repair of cleft lip and cleft hard palate with vomer flap.

To date, there have been no reports of patients showing a Tessier number 7 cleft with unilateral complete cleft lip and palate. Furthermore, no studies have established the sequence, plan, or timing of surgical methods for treating patients presenting the above anomalies simultaneously. We report a case of a Tessier number 7 cleft with unilateral complete cleft lip and palate. Two months after birth, lip adhesion was performed on the unilateral complete cleft lip and total excision was performed on the skin tag. At 4 months of age, Tessier number 7 cleft was corrected. At 6 months of age, surgery involving two small triangular flaps was performed on the unilateral incomplete cleft lip after performing lip adhesion. At 13 months of age, two-flap palatoplasty with a vomer flap was performed on the complete cleft palate. At 6 years of age, open rhinoplasty was performed on the unilateral cleft lip nose deformity. At 9 years of age, bone grafting was performed for the alveolar cleft. At follow-up appointments up to 13 years of age, there were no major complications. Here, we present this patient, surgical procedures and timelines, and show our results demonstrating good postoperative outcomes.

Background Bilateral cleft lip deformity is much more difficult to correct than unilateral cleft lip deformity. The complexity of the deformity and the sensitive relationships between the arrangement of the muscles and the characteristics of the external lip necessitate a comprehensive preoperative plan for management. The purpose of this study was to evaluate the repair of bilateral cleft lip using the Byrd modification of the traditional Millard and Manchester methods. A key component of this repair technique is focused on reconstruction of the central tubercle. Methods Fourteen patients with mean age of 5.7 months presented with bilateral cleft lip deformity and were operated on using a modification of the Millard and Manchester techniques. Patients with a very wide cleft lip and protruded or rotated premaxilla were excluded from this study. We analyzed 30 normal children for a comparison with our patients in terms of anthropometric measurements. Results By the end of the follow-up period (between 9 and 19 months), all our patients had obtained a full central segment with adequate white roll in the central segment and a deep gingivolabial sulcus, and we obtained nearly normal anthropometric measurements in comparison with age-matched normal children. Conclusions We recommend this modified technique for the treatment of bilateral cleft lip deformity.

Lip defects often occur following wide excision as a surgical treatment for squamous cell carcinoma of the oral cavity. Defects larger than one-half of the lip cannot be closed primarily and require flap surgery. Reconstruction of the oral sphincter function can be achieved by means of a local flap using the like tissue, rather than with a free flap utilizing different tissues. A defect of the lower lip requires reconstruction using different techniques, depending on its size and location. Herein, we present the case of a patient exhibiting a lip defect spanning more than two-thirds of the lower lip, after a wide resection due to squamous cell carcinoma. The defect was reconstructed using an Abbe flap and a staircase flap. Revision was performed after 16 days. The patient's oral competencies were fully restored 3 months postoperatively, and the esthetic results were ideal. Based on our experience, a combination of the Abbe and staircase flaps can produce excellent functional and esthetic outcomes in the reconstruction of a lower lip with a large defect. It can serve as a reliable reconstruction option for defects spanning more than two-thirds of the lower lip, not including the oral commissures.

Lower lip reconstruction in cases with a full-thickness defect over one-third of the vermilion is challenging. Numerous conventional techniques have been applied with unsatisfactory surgical outcomes because of microstomia and oral commissure blunting due to shortened horizontal lip length. Herein, we present a case in which a full-thickness lower lip defect of more than one-third of the horizontal lip length was covered with a novel mucosal roofing flap reconstruction to minimize the loss of horizontal lip length and to preserve mouth opening. No recurrences or metastases were observed during 3 years and 6 months of follow-up, with horizontal lower lip length maintained and mouth opening of 2.5 finger breadths.
