AbstractBackgroundNasal deformity associated with cleft lip deformity is a challenging issue, encompassing controversies, theories, and a diversity of techniques. Historically, esthetic outcomes have ranged from being below expectations to barely acceptable.MethodBased on the concept that the nasal cartilaginous framework in clefts is similar to that of a collapsing pyramid, a novel suspension technique has been described. The entire cartilaginous structure is lifted from the infratip segment with a loop suture and is secured in a cantilever fashion onto the periosteum overlying the nasal bone. This part of the operation is performed in a semiclosed manner. The technique is applied during primary surgery in bilateral and unilateral nasal cleft lip deformities, with changes in the orientation of the cantilever loop suture. Studies conducted by Masters S. Tajima, H. McComb, H. Thomson, D. Fisher, and J. Mulliken, which are most relevant to this article, have been reviewed and discussed throughout.ResultsThe technique was first applied over 10 years ago. A case series of nine children whose parents consented to the developing technique is presented with follow-up ranging from months to years, along with technical descriptions and illustrative drawings. None of these cases had preoperative orthopedic correction, molding, or postoperative nostril splints. The esthetic outcome was optimal enough; none of the cases requested a secondary correction.ConclusionThe nasal cantilever technique is a novel concept in cleft nasal deformity, which can be used in conjunction with an appropriate lip technique, per the surgeon’s discretion. Other than a learning curve, we believe that it provides a solid correction by securing the cartilaginous structures after they have been mobilized to a stable base, the nasion.

Although primary surgery for cleft lip has improved over time, the degree of secondary cleft or nasal deformity reportedly varies from a minimum degree to a remarkable degree. Patients with cleft often worry about residual nose deformity, such as a displaced columella, a broad nasal floor, and a deviation of the alar base on the cleft side. Some of the factors that occur in association with secondary cleft or nasal deformity include a deviation of the anterior nasal spine, a deflected septum, a deficiency of the orbicularis muscle, and a lack of bone underlying the nose. Secondary cleft and nasal deformity can result from incomplete muscle repair at the primary cleft operation. Therefore, surgeons should manage patients individually and deal with various deformities by performing appropriate surgery on a case-by-case basis. In this report, we applied the simple method of single VY-plasty on the nasal floor to a patient with unilateral cleft to revise the alar base on the cleft side. We adopted this approach to achieve overcorrection on the cleft side during surgery, which helped maintain the appropriate position of the alar base and ultimately balanced the nose foramen at 13 months after the operation. It was also possible to complement the height of the nasal floor without a bone graft. We believe that this approach will prove useful for managing cases with a broad and low nasal floor, thereby enabling the reconstruction of a well-balanced nose.

Objectives: To evaluate the magnitude of olfactory recess opacity in patients with unilateral cleft lip nasal deformity (uCLND). Design: Subject-specific 3-dimensional reconstruction of the nasal airway anatomy was created from computed tomography images in 11 (4 males and 7 females) subjects with uCLND and 7 (3 males, and 4 females) normal subjects. The volume and surface area of each subject’s unilateral and bilateral olfactory airspace was quantified to assess the impact of opacification. Qualitatively speaking, patients with 75% to 100% olfactory recess opacification were classified as extreme, 50% to 75% as severe, 25% to 50% as moderate, and 0% to 25% as mild. Results: Of the 11 subjects with uCLND, 5 (45%) were classified as having extreme olfactory recess opacification, 3 (27%) subjects had severe opacification, and 3 (27%) subjects had moderate opacification. Mean (±SD) bilateral olfactory recess volume was significantly greater in normal subjects than in subjects with uCLND (0.9668 cm3 ± 0.4061 cm3 vs 0.3426 cm3 ± 0.1316 cm3; P < .001). Furthermore, unilateral olfactory airspace volumes for the cleft and non-cleft sides in subjects with uCLND were considerably less than unilateral olfactory volume in subjects with normal anatomy (uCLND cleft side = 0.1623 cm3 ± 0.0933 cm3; uCLND non-cleft side = 0.1803 cm3 ± 0.0938 cm3; normal = 0.4834 cm3 ± 0.2328 cm3; P < .001). Conclusions: Our findings indicate a high prevalence of olfactory recess opacification among subjects with uCLND when compared to subjects with normal anatomy. The majority of subjects with uCLND had extreme olfactory recess opacity, which will likely influence their sense of smell.

AbstractNanographenes are emerging as a distinctive class of functional materials for electronic and optical devices. It is of remarkable significance to enrich the precise synthetic chemistry for these molecules. Herein, we develop a facile strategy to recompose helicenes into chiral nanographenes through a unique oxidative cyclo-rearrangement reaction. Helicenes with 7~9 ortho-fused aromatic rings are firstly oxidized and cyclized, and subsequently rearranged into nanographenes with an unsymmetrical helicoid shape through sequential 1,2-migrations. Such skeletal reconstruction is virtually driven by the gradual release of the strain of the highly distorted helicene skeleton. Importantly, the chirality of the helicene precursor can be integrally inherited by the resulting nanographene. Thus, a series of chiral nanographenes are prepared from a variety of carbohelicenes and heterohelicenes. Moreover, such cyclo-rearrangement reaction can be sequentially or simultaneously associated with conventional oxidative cyclization reactions to ulteriorly enrich the geometry diversity of nanographenes, aiming at innovative properties.

Objective: To formulate a standardized procedure for repair of the nasal component of Tessier number 1 and 2 clefts. Patients and Methods: The procedure was performed from 1998 to 2007 in 13 patients with congenital nasal clefts of different degrees of expression corresponding to Tessier 1 and 2. The patients’ ages ranged from 3 months to 28 years. There were 10 male and three female patients. In the absence of any standard published technique for these rare defects, we devised our own method, which we find uniformly applicable to all such cases. We use a composite muco-chondro-cutaneous lateral alar flap to recreate the alar rim. The resulting defect on the lateral nasal wall is then covered with a transposition flap from the dorsum. An alar rim z-plasty was added in cases where notching was evident. Results: In all cases, no problem of flap viability was encountered and all healed well with minimal scarring. The postoperative results were satisfactory and have remained stable over an average 6-month follow-up period. Conclusions: We recommend this technique to be used for the correction of nasal deformity associated with Tessier clefts number 1 and 2. We feel that this technique is relatively simple and easily reproducible.
