Background: Patients with secondary deformities associated with unilateral cleft lip and nose might also suffer from nostril stenosis due to a lack of tissue volume in the nostril on the cleft side. Here, we used full-thickness skin grafts (FTSGs) to reduce nostril stenosis and various methods for skin volume augmentation. We compared the changes in the symmetry of both nostrils before and after surgery. Methods: From February 2016 to January 2020, 34 patients underwent secondary cheiloplasty and open rhinoplasty for secondary deformities of the unilateral cleft lip and nose with nostril stenosis. FTSG was used on the nostril floor, nasal columella, and alar inner lining. The measured nasal profile included the nostril surface, nostril circumference, width of the nostril floor, and distance from the alar-facial groove to the nasal tip. The “overlap area,” which was defined as the largest overlapping area when the image of the cleft nostril was flipped to the left and right and overlaid on the image of the normal side nostril, was also calculated. The degree of symmetry was evaluated by dividing the value of the cleft side by that of the normal side of each measured profile and expressed as “ratios.” Results: The results of all profile ratios, except for the nostril floor width, became significantly close to 1, which represents full symmetry. The overlap area ratio improved from 62.7% to 77.3%, meaning that the length and width of the nostril as well as the overall shape became similar (p< 0.05). Conclusion When performing cleft rhinoplasty with nostril stenosis, FTSG is useful to achieve symmetry in the nostril size and shape. Skin grafting is simpler to perform than the other types of local flap, and the results are generally satisfactory.

Posterior lumbar apophyseal fracture characterized by osteochondral fragments from posterior rim of a lumbar vertebral body, has often been misdiagnosed as herniated disc or spinal stenosis due to its similarity of symptoms. But recent use of CT scan facilitated the diagnosis of the lesion as a separate entity. This study was performed to verify the clinical characteristics, to find out the mechanism of injury and to determine the most effective method of diagnosis and treatment. Authors reviewed 17 patients(14 male, 3 female) who were subjected to surgical treatment at Department of Orthopaedic Surgery, Seoul National University Hospital for posterior lumbar spophyseal fracture during the period of 1990-1992, and followed up for average of 1 year and 6 months(range 1 to 3 years). Thirteen patients (76%) were related to a history of trauma or strenuous physical activity prior to the onset of symptoms. The mechanism of injury was the rapid flexion with axial compression in 7, hyperextension in 4, and pure axial compression in 2 patients. The mean age at the time of injury was 20 years(range 10 to 31 years). All patients presented low-back pain radiating to lower extremities and 11 patients showed neurogenic intermittent claudication. The mean age at the time of surgical intervention was 23 years and 10 months(range 15 to 31 years), and the mean duration of symptoms was 3 years(range 2 months to 13 years). Simple X-ray revealed the lesion in only 3 cases but CT scan demonstrated the characteristic osteochondral fragment displaced posteriorly into the spinal canal and the corresponding defect with degenerative changes in all patients. The fracture occured through the superior apophyseal rim of L5 in 9 superior rim of L4 in 3, inferior rim of L4 in 2, inferior rim of L5 in, superior rim of L2 in 1, and superior rim of L1 in 2 patients. Two patients had concomitant fractures at two levels. All patients except one were treated with posterior decompression including the removal of the displaced fragment and posterolateral fusion with pedicular screws was carried out to prevent further degenerative change and instablilty. One patient with the lesion at the superior rim of L1 was treated by anterior decompression and fusion. All patients showed relief of pain and claudication with satisfactory results. One patient had partial tear of L4 root with slight weakness of greater toe dorsiflexion, but it recovered in 4 months. In conclusion, posterior lumbar spophyseal fracture predominantly affected young males and the most common causative mechanism was rapid flexion with axial compression. The CT scan facilitated identification of the lesion. The most frequently affected site was the superior rim of L5. Satisfactory results could be achieved bvy adequate posteriior decompression with the removal of the fragment and posterolateral fusion with pedicular screws.

Laparoscopic wedge resection for treating a gastric submucosal tumor is a widely accepted and feasible procedure. As the skills for performing laparoscopic surgery have been developed, a great deal of effort has also been given to minimize the size of the abdominal wound and its scar. Some studies have introduced single port laparoscopic surgery for these purposes, but most of these single port laparoscopic surgeries were carried out to perform appendectomy and cholecystectomy. There have been fewer reports on this for gastric surgeries. We report here on 2 cases of single port laparoscopic gastric wedge resection for treating gastric submucosal tumor.

Primary splenic tumors are rare and mainly found incidentally on radiologic studies. Among them, sclerosing angiomatoid nodular transformation (SANT) of the spleen is a new entity defined as a benign pathologic lesion. Most SANTs have no clinical symptoms and are occasionally accompanied by other splenic diseases such as malignancies. So, the exact diagnosis of the nature of the splenic tumor is mandatory for further treatment. But, preoperative diagnosis is not easy since it is difficult to obtain the tissue from the spleen for pathological study. Recently, laparoscopic splenectomy has become the more standard procedure for the spleen for diagnosis and treatment. Here, we report a rare case of SANT diagnosed following laparoscopic splenectomy.
