The septal extension graft from the septum has become a common method of correcting a small or drooping nose in Korea. It can provide superior tip projection and definition if there is a sufficient amount of cartilage and nasal septal stability. In our case, the caudal type septal extension graft was applied unilaterally using septal osteocartilaginous graft harvested in one piece during septoplasty. It was useful in patients who needed septal extension graft in spite of the insufficient amount of available septal cartilage. For those patients, it could be used to achieve the cephalic rotation of drooping tip and the strengthening of septal support effectively. The nasal septal osteocartilaginous graft may serve as an alternative material for conchal cartilage or costal cartilage for caudal septal extension graft if the stable nasal support is maintained and the harvested graft is applied appropriately.

OBJECTIVES: This study aimed to measure the dimensions of the nasal septal cartilage in adult Filipino Malay cadavers and calculate the cartilage area as well as the amount of graft material that can be harvested from the septal cartilage.

METHODS:
Design: Descriptive, cross-sectional
Setting: Pamantasan ng Lungsod ng Maynila College of Medicine Anatomy Laboratory
Subjects: Ten preserved adult cadavers dissected within a period from September 2010 to October 2010. The septal cartilages were harvested and the lengths of the cephalic margin, dorsal margin, caudal margin and ventral margin were measured. From these measurements, the total area of the cartilage and the amount of graft material that can be harvested were calculated.

RESULTS: The mean length of each margin of the septal cartilage was 25.9mm (cephalic edge), 22.3 mm (dorsal edge), 21.4mm (caudal edge) and 33.1 mm (ventral edge). The area of the septal cartilage had a mean value of 652.5 mm². The amount of septal cartilage which can be harvested had a mean area of 403mm².

CONCLUSION: This study showed a slight decrease in septal cartilage area to 652.5 mm² and in available graft material to 403 mm². While this decrease may reflect the apparently smaller noses of native Southeast Asians compared to East Asians and South Asians, the difference in values can also be due to the difference in the number of subjects or in methods of measurement and further studies are recommended to determine the extent of inter-racial variability.

BACKGROUND AND OBJECTIVES: The nasal septum, centrally located in the nasal cavity, has dynamic relations with other craniofacial structures and is also influenced by them during development. Moreover, the mosaic structure of the septum is constituted through ossification. The purpose of this study was to evaluate the anatomical characteristics of the deviated nasal septum with preoperative computed tomography (CT) and calculations during surgery. SUBJECTS AND METHOD: We studied 62 patients with nasal septal deviation on one side, who underwent septoplasty between July 2008 and February 2009. The area of the septal cartilage, vomer, and perpendicular plate of the ethmoid bone was calculated with sagittal imaging using preoperative CT. The angle of deviation was also measured with coronal imaging. The length between the anterior nasal spine and sphenoidal sinus and that of the sphenoidal process was measured during surgery. RESULTS: The deviation angle increased significantly with the length of the sphenoidal process (p<0.01). The area of the septal cartilage decreased with age due to the progression of ossification. CONCLUSION: Nasal septal deviation without a history of trauma is influenced by the progression of nasal septal ossification.

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.

OBJECTIVETo explore the effect of four line tension relaxing septorhinoplasty for nasal deviation complicated with the deformity of nasal septal cartilage under endoscope.

METHODSSeventeen patients with nasal septum deviation from December 2009 to April 2011 were included in this study. The patients were divided into different groups depending on different deformity of quadrangular cartilage. Different surgical methods were used according to different deviation of nasal septum. First, a C-shape or L-shape incision was made on one side of the nasal septum under endoscope, then the nasal septal cartilage was separated from the angle formed by two greater alar cartilages, perpendicular plate of the ethmoid bone, the junction of vomer and maxilla at the nasal crest, and the upper lateral cartilage, this procedure was applied to correct deviation of nasal septum and nasal pyramid by decompression, which was named four lines tension relaxing correction.

RESULTSSeventeen patients with nasal septal deviation obtained satisfied curative effect. Nasal deviation and deviation of nasal septum were all corrected, patients got better appearance and good nasal ventilation, no complication was observed.

CONCLUSIONNasal deviation complicated with the deformity of nasal septal cartilage could be completely corrected by only one septorhinoplasty operation--four lines tension relaxing correction.

Collapse of the nasal valve is a rare cause of nasal obstruction in Asians, though it is relatively common in Caucasians. The thick skin and wide internal nasal valve angle were considered to contribute to the rarity of this entity. However, it does exist in Asians, especially who have thin skin and weak, collapsible nasal cartilages. The authors treated 2 patients with dynamic nasal valve collapse with cartilage grafts reinforcing the epicenter of valve collapse. This paper presents 2 cases of dynamic nasal valve collapse and introduces surgical maneuvers which were successfully applied to these cases.

Objective: To present a rare case of nasal tip schwannoma and describe its resection and reconstruction using combined cartilage grafts. Methods: Design: Case Report Setting: Tertiary Government Training Hospital Patient: One Results: A 13-year-old boy presented with a progressively enlarging nasal tip and severe left nasal obstruction causing breathing difficulties and psychosocial distress. There was a bulging septal mass obstructing 90% of the left nasal cavity. Septal incision biopsy revealed schwannoma and definitive surgery via open rhinoplasty approach was done. The non-encapsulated schwannoma extended from the subcutaneous nasal tip to the left septal mucosa. There was no evidence of skin or cartilage invasion, but prolonged pressure from the expansile schwannoma caused severe lower lateral cartilage and anterior septal atrophy leading to a collapsed and expanded nasal tip after resection. To correct this, a total reconstruction of the anterior tip complex was done using combined ear cartilage seagull wing graft, shield graft and septal extension graft. Conclusion Nasal tip and septal schwannoma is rare and can cause significant nasal obstruction and deformity. Complete excision is vital to avoid recurrence. Total reconstruction of the lower lateral cartilages using autologous septal and ear cartilage grafts may be a safe and effective technique that yields acceptable aesthetic results.

OBJECTIVE: To investigate the influence of buried thread nasal augmentation on dorsal soft tissue of nose and revision rhinoplasty. METHODS: A clinical data of 29 patients requesting revision rhinoplasty after buried thread nasal augmentation, who were admitted between July 2017 and July 2019 and met the selection criteria, was retrospectively analyzed. All patients were female with an average age of 26.8 years (range, 18-43 years). The patiens were admitted to the hospital at 3-48 months after buried thread nasal augmentation (median, 15 months). Among them, there were 18 cases of insufficient nasal tip projection, 22 cases of insufficient nasal root projection, 7 cases of threads ectasia, 5 cases of threads exposure, 3 cases of infection, and 10 cases with two or more conditions. There were 9 cases of combined short nose deformity, 1 case of spherical hypertrophy of the nasal tip, 3 cases of deviation of the nasal columella, 3 cases of excessive width of the nasal base, and 1 case of nasal hump. Three infected patients only underwent threads removal and debridement. The rest patients underwent revision rhinoplasty, and the dorsum of the nose was made with polytetrafluoroethylene expansion; the tip of the nose was reshaped by taking autologous rib cartilage and alar cartilage in 16 cases, and by taking autologous septal cartilage and alar cartilage in another 10 cases. The threads and surrounding tissue specimens removed during operation were subjected to histologic observation. Nasal length and nasal tip projection were measured after revision rhinoplasty and the ratio was calculated to evaluate the nasal morphology; patient satisfaction was evaluated using the Likert 5-grade scale. RESULTS: Patients were followed up 12-48 months (mean, 18 months). Inflammation was controlled in 3 patients with infections caused by buried thread nasal augmentation. The remaining 26 patients had satisfactory results immediately after revision rhinoplasty. Before revision rhinoplasty and at 7 days and 6 months after revision rhinoplasty, the nasal length was (4.11±0.34), (4.36±0.25), and (4.33±0.22) cm, respectively; the nasal tip projection was (2.34±0.25), (2.81±0.18), and (2.76±0.15) cm, respectively; and the nasal tip projection/nasal length ratio was 0.57±0.08, 0.65±0.05, and 0.64±0.04, respectively. There were significant differences in the nasal length and the nasal tip projection between time points ( P<0.05). There was a significant difference in the nasal tip projection/nasal length ratio between pre- and post-operation ( P<0.05), but there was no significant difference between 7 days and 6 months after operation ( P>0.05). The Likert score for satisfaction ranged from 1.5 to 5.0 (mean, 4.05). During follow-up period of 26 patients, no nasal prosthesis was exposed, and the shape of the nose was stable, and the nasal skin of 5 patients with exposed threads could be seen with different degrees of scarring; there was no infection, cartilage resorption, and no cartilage deformation, displacement, or exposure. Histological observation showed that absorbable threads were not only absorbed after implantation, but also with the prolongation of time, the inflammatory changes in the surrounding tissues caused by decomposition and absorption of the threads showed a gradual aggravation of the first, the heaviest inflammatory reaction in 6 to 12 months, and then gradually reduce the trend. CONCLUSION After implantation of the absorbable thread into the subcutaneous tissue of the nasal dorsum, the nature of the thread is different from the body's own tissue, which will affect the soft tissue compliance of the nasal dorsum. The degradation and absorption of the thread will stimulate the infiltration of inflammatory cells and the proliferation of fibroblasts in the surrounding tissue and then form scar tissue, which will affect the design and effect of revision rhinoplasty.

BACKGROUND: The number of surgical risks recalled by a patient after surgery can be used as a parameter for assessing how well the patient has understood the informed consent process. No study has investigated the usefulness of a self-developed mobile application in the traditional informed consent process in patients with a nasal bone fracture. This study aimed to investigate whether delivery of information, such as surgical risks, through a mobile application is more effective than delivery of information through only verbal means and a paper. METHODS: This prospective, randomized study included 60 patients with a nasal bone fracture. The experimental group (n=30) received preoperative explanation with the traditional informed consent process in addition to a mobile application, while the control group (n=30) received preoperative explanation with only the traditional informed consent process. Four weeks after surgery, the number of recalled surgical risks was compared for analysis. The following six surgical risks were explained: pain, bleeding, nasal deformity, numbness, nasal obstruction, and nasal cartilage necrosis. RESULTS: The mean number of recalled surgical risks among all patients was 1.58±0.56. The most frequently recalled surgical risk was nasal deformity in both groups. The mean number of recalled surgical risks was 1.72±0.52 in the experimental group and 1.49±0.57 in the control group. There was a significant association between mobile application use and the mean number of recalled surgical risks (p=0.047). Age, sex, and the level of education were not significantly associated with the mean number of recalled surgical risks. CONCLUSION: This study found that a mobile application could contribute to the efficient delivery of information during the informed consent process. With further improvement, it could be used in other plastic surgeries and other surgeries, and such an application can potentially be used for explaining risks as well as delivering other types of information.

A 65-year-old woman with a deeply infiltrating basal cell carcinoma in the right ala underwent full-thickness excision of most of the ala, including the alar rim, crease, and the adjacent cheek, leaving a 'through-and-through' defect. Reconstruction was performed by using the reverse nasolabial flap and a cartilage graft across the alar defect, harvested from the concha, to prevent nostril collapse and to maintain the alar shape. The reverse or turnover nasolabial flap is a variant of the conventional nasolabial flap; however, it may be more suited for the repair of a full-thickness, lateral alar defect. The reverse nasolabial flap functions both as an inner liner and an outer cover and the repair is performed as a single-stage procedure. Furthermore, this flap can provide both excellent function and excellent cosmetic outcome.
