A wide variety of deformities can occur following repair of the cleft lip. Especially, cleft lip nasal deformities offer the severe psychologic, esthetic, and functional impairment. We must restore the deformities of alar cartilge, nasal tip, septum, columella, or pyriform aperture. The authors reconstructed the cleft lip nasal deformities using with the alar cartilage rearrangement, postauricular cartilage graft, and/or columellar lengthening. The 3 case reports are presented.

Purpose: The importance of the deformities in alar - columellar complex has been underestimated in Asian ethnic groups for the last decades. Fortunately, with increasing familiarity of the open rhinoplasty techniques, the anatomic details of the nasal tip have been pointed up. Definitely, having an interest and demand for improving the sub - normal relationship between the alar rim and columella are indebted for such growing of knowledge about nasal tip anatomy. However, it is true that any single procedure is not settled as versatile and fully confident modality to correct the retracted notching of the alar rim. With this article, I should like to propose another useful option for treating retracted ala. Methods: The author has tried to correct alar rim retraction by means of: (1) Triangular onlay septal cartilage graft on the lower lateral cartilage with the medial end fixed to the anterior surface of the lateral crus(Alar extension graft), (2) Inserting lateral end of the alar extension graft to the vestibular skin pocket in the form of a finger - in - groove, (3) using the vestibular skin in the form of an advancement flap, and (4) using the soft shield graft to prevent possible visible step - off of the alar margin. Results: The author applied an alar extension graft to 16 patients in order to correct a retracted ala for the last 27 months (August, 2003 - October, 2005). The distances from alar rim to long axis of nostril were improved to be within 2 mm in all of the cases, and also the shape of the alar rim changed to a round form. Nostril asymmetry (6%) in one case, temporary palpable step - off (18%) in three cases, temporary visible step - off (6%) in one case, and temporary paresthesia of the tip (25%) in four cases were observed. Conclusion: The alar extension graft is simple and efficacious. It does not need donor sites other than the operative field, and its results are predictable. In particular, since it may give structural intensity to a weak lower lateral cartilage, it may be preferentially used for the correction of a retracted ala that arises from hypoplastic lower lateral cartilage. Moreover intensified lower lateral cartilage also improves the esthetic shape of lobule.

In patients having a short nose with a short septal length and/or severe columellar retraction, a septal extension graft is a good solution, as it allows the dome to move caudally and pushes down the columellar base. Fixing the medial crura of the alar cartilages to a septal extension graft leads to an uncomfortably rigid nasal tip and columella, and results in unnatural facial animation. Further, because of the relatively small and weak septal cartilage in the East Asian population, undercorrection of a short nose is not uncommon. To overcome these shortcomings, we have used the septal extension graft combined with a derotation graft. Among 113 patients who underwent the combined procedure, 82 patients had a short nose deformity alone; the remaining 31 patients had a short nose with columellar retraction. Thirty-two patients complained of nasal tip stiffness caused by a septal extension graft from previous operations. In addition to the septal extension graft, a derotation graft was used for bridging the gap between the alar cartilages and the septal extension graft for tip lengthening. Satisfactory results were obtained in 102 (90%) patients. Eleven (10%) patients required revision surgery. This combination method is a good surgical option for patients who have a short nose with small septal cartilages and do not have sufficient cartilage for tip lengthening by using a septal extension graft alone. It can also overcome the postoperative nasal tip rigidity of a septal extension graft.

The characteristics of the cleft lip nasal deformity is defined in this article in three planes. The alar flaring is explained in X axis, the lower positioning of the alar free margin is imagined in Y axis and the short hemicolumella is in Z axis. Most cleft surgeons have focused on the malposition of the lateral crus of alar cartilage while the author defined it in X and Y axises and tried to correct that deformity of short hemicolumella in Z axis. For the last 13 years the author applied that method in 818 cases of secondary cleft lip nose deformity. Through the columellar splitting incision extended to free margin of the alar not beyond the nasal dorsum, the skin and soft tissue of the webbing deformed the nasal tip was excised in crescent fashion. The dissected short hemicolumella including the medial crus was thus elevated and advanced into the space of the deformed nasal tip after the crescent excision. This procedure should be followed by the correction of the deformities in X and Y axis. The medial crus elevation is more effective and critical way to have the constant and nice outcome than the lateral crus reposition in secondary cleft lip nasal deformity

Purpose: Complete septal extension grafts have been widely used in rhinoplasty for effective projection of the short retruded columella in Asian patients. Autologous septal cartilages and porous high-density polyethylene sheets are frequently used as septal extension grafts. This study was conducted to compare the postoperative results of porous polyethylene sheets and septal cartilages used for correction of unilateral cleft lip nasal deformities by using photogrammetric analysis. Methods: This study investigated a total of 49 patients with cleft lip nasal deformities who underwent corrective surgery, and were followed up for at least 6 months. Septal cartilages were used in 39 patients, and porous polyethylene sheets were used in 10 patients. In all patients, through the open rhinoplasty, complete septal extension grafts were sutured to the caudal margin of the septal cartilage, and the alar cartilage was sutured with suspension. The cleft side alar cartilage was overcorrected by approximately 3 - 5 mm. Postoperative outcomes were evaluated by using photogrammetric analysis. Five indices and 4 angles were measured on their photographs taken before and after the surgery. In patients with unilateral cleft lip nasal deformities, symmetry was also evaluated by means of columellar length index. Results: The postoperative values obtained in photogrammetric analysis showed improvements in comparison with the preoperative ones. The polyethylene group produced more improved outcomes than the septal cartilage group but also resulted in more complications at the same time. Conclusion: The results of this study indicates that complete septal extension grafts are efficient for the correction of unilateral cleft lip nasal deformities. However, since postoperative complications occur more frequently in the polyethylene group than in the septal cartilage group, caution is advised in using porous high-density polyethylene sheets in patients with cleft lip nasal deformities.

The alar base on the cleft side in unilateral complete cleft lip, alveolus and palate is markedly displaced laterally, caudally and dorsally, By incising the pyriform margin from the cleft margin of the alveolar process, including mucosa of the anterior part of the inferior turbinate, to the upper end of the postnasal vestibular fold, the alar base is released from the maxilla, A physiological correction of nasal deformity can be accomplished by careful reconstruction of nasolabial muscle integrity, functional repair of the orbicular muscle, raising and rotating the displaced alar cartilage, and finally by lining the lateral nasal vestibule, The inferior maxillary head of the nasal muscle complex is identified as the deeper muscle just below the web of the nostril, The muscle is repositioned inframedially, so that it is sutured to the periosteum that overlies the facial aspect of the premaxilla in the region of the developing lateral incisor tooth, And then, the deep superior part of the orbicular muscle is sutured to the periosteum and the fibrous tissue at the base of the septum, just in front of the anterior nasal spine, The nasal floor is surgically created by insertions of the nasal muscle complex in deep plane and of the orbicular muscle in superficial one, The upper part of the lateral nasal vestibular defect is sutured by shifting the alar flap cephalically, The middle and lower parts of this defect are closed by use of cleft margin flaps of the philtral and lateral segments, respectively, Authors stress the importance of nasal floor reconstruction at primary surgery and report the technique and postoperative results.

The author presents Bardach' s technique for the residual unilateral cleft lip nasal deformity, The key to a successful and stable correction of the nasal deformity is to lengthen the columella on the cleft side and to mobilize alar cartilage from its surrounding tissue, creating a symmetric shape and length, The major advantages of the technique are lengthening of the cleft columella and creation of a symmetric and well-projected nasal tip.

Background Nasal framework-supporting procedures such as septal extension grafts, derotation grafts, and columellar strut grafts are usually required in rhinoplasty in Asian patients because the skin envelope is tight, but the nasal framework is small and weak. Autologous materials are preferred, but they have some limitations related to the amount that can be harvested and the frequency of use. Therefore, synthetic materials have been used to overcome these limitations. Methods A total of 114 patients who received a polydioxanone (PDS) plate as an adjuvant material in rhinoplasty from September 2016 to August 2017 were retrospectively investigated. The PDS plate was used as to support the weak framework and to correct the contour of the alar cartilages. The PDS plate was used for reinforcement of columellar struts and septal L-struts, alar cartilage push-down grafts, fixation of septal extension grafts, and correction of alar contour deformities Results Primary and secondary rhinoplasty was performed in 103 and 11 patients, respectively. Clinically, no significant inflammation occurred, but decreased projection of the tip was observed in seven patients and relapse of a short nose was noted in five patients. Conclusions PDS plates have been used in the United States and Europe for more than 10 years to provide a scaffold for the nasal framework. These plates can provide reinforcement to columellar struts, L-struts, and septal extension grafts. In addition, they can assist in deformity correction. Therefore, PDS plates can be considered a good adjuvant material for Asian patients with weak and small nasal cartilage.

Full-thickness nasal tip reconstruction is a challenging process that requires provision of ample skin and soft tissue, and intricate cartilage structure that maintains its architecture in the long term. In this report, we describe reconstruction of a full-thickness nasal tip and ala defect using a posterior auricular artery perforator based chondrocutaneous free flap. The flap consisted of two lay ers of skin covering conchal cartilage, and was based on a perforating branch of the posterior auricular artery. A superficial vein was secured at the posterior margin. The donor perforator was anastomosed to a perforating branch of the lateral nasal artery. The superficial vein was connected to a superficial vein of the surrounding soft tissue. The donor healed well after primary closure. The flap survived without complications, and the contour of the nasal rim was sustained at follow-up 6 months later. As opposed to combined composite reconstructions using a free cartilage graft together with a small free flap or pedicled nasolabial flap, the posterior auricular artery perforator free flap encompasses all required tissue types, and is similar in contour to the alar area. This flap is a useful option in single-stage reconstruction of nasal composite defects.
