Background The partial cutting and suture technique is a modification of the cutting and suture technique that overcomes the limitations and simplifies the procedure of the cutting and suture technique. Objective We describe the partial cutting and suture technique and evaluate its effectiveness of correcting caudal septal deviation. Methods We retrospectively reviewed the medical records of patients who underwent anterior septoplasty using the partial cutting and suture technique. The patients were evaluated with the Nasal Obstructive Symptoms Evaluation (NOSE) scale scores and the acoustic rhinometry preoperatively and 3 months postoperatively. Results Thirty-one patients underwent caudal septoplasty by our novel technique. The NOSE scale score changed from 43.5 to 11.0 ( P = .000). The minimal cross-sectional area (MCA) on the convex side changed from 0.49 cm2 to 0.65 cm2 ( P = .006). Conclusion The partial cutting and suture technique is relatively easy and is very effective in correcting caudal septal deviation without any complications.

Background The aim of this study was to determine the characteristics of acoustic rhinometric parameters in patients with paradoxical nasal obstruction. Methods The medical records of 1844 patients who had nasal septal deviation between 1998 and 2004 at our institute were assessed retrospectively. The authors selected 31 subjects for the experimental group and 256 subjects for the control group. Minimal cross-sectional area (MCA), volume, and degree of mucosal change at baseline and decongested phase were analyzed. Results MCA of the convex side in the baseline state for the experimental (paradoxical) group is wider than that for the control group (p = 0.005). Degree of mucosal change of the experimental group is smaller than that of the control group in the convex side (p = 0.001). Other parameters are similar for the two groups. Conclusion Patients with paradoxical nasal obstruction might be explained by less degree of mucosal change in the concave side of the nasal cavity during nasal cycle than the control group.

Objective: There are several types of septal deviation, including horizontal, vertical, C-shaped, S-shaped, and high deviation. One of the most difficult of these types to correct is the crooked dorsal septum, which attaches to the upper lateral cartilage and causes a high septal deviation. We propose a method for horizontal dorsal resection of a crooked septum using a mucosal through-and-through suture technique for the correction of high septal deviation. Design and setting: The medical records of 30 patients (27 men) who underwent septoplasty by one author of this study from 2019 to 2020 at our institute were reviewed prospectively. The median follow-up was 11 months (range, 4–16 months). All patients underwent a horizontal dorsal septal cartilaginous resection with mucosal through-and-through suture. Data were collected on demographics, symptoms, anatomic site of deviation, and postoperative complications. Patient self-satisfaction scores were subjectively graded using a visual analog scale ranging from 0 (excellent) to 10 (poor). Results: One surgeon performed each septoplasty using the same method; 2 (6.7%) patients underwent additional valvuloplasty. The median scores in subjective satisfaction for the 30 patients were 8.4±1.22 before surgery and 2.07±1.26 after surgery (p<0.05). Furthermore, no patient experienced a saddle deformity, septal hematoma, septal perforation, or loss of nasal tip support during follow-up. Conclusions: After horizontal dorsal resection from the upper lateral cartilage during septoplasty, the patients experienced no stability problems. This suggests that this surgical technique is a safe and effective method for correcting high deviation due to a crooked dorsal septum.

The present study deals with the indication for inferior turbinate surgery in cases of concomitant anterior septal deviation. We define, by acoustic rhinometry, the characteristics of the obstructed nose and define mucosal turbinate hypertrophy. A random sample of 80 patients with nasal obstruction and anteriorly located septal deviation were objectively evaluated by acoustic rhinometry pre– and post–operatively. All had septoplasty and half were randomly selected to have anterior inferior turbinoplasty performed in the side opposite to the major septal deviation. Severe septal deviation, expressed by a minimal cross–sectional area less than 0.4 cm2 was present in 37 patients. In this group inferior turbinate reduction seems advisable. In the wide side, the minimal cross–sectional area and the cross–sectional areas at 3.3 and 4.0 cm from the nostrils increased in the turbinectomy group and decreased in the non–turbinectomy group after correction of the septal deviation. In the group with less pronounced septal deviation no influence of turbinate reduction could be detected.

Post Operative Complications

SummaryDuring a triple pelvic osteotomy, rotation of the free acetabular segment causes the pubic remnant on the acetabulum to rotate into the pelvic canal. The resulting narrowing may cause complications by impingement on the organs within the pelvic canal. Triple pelvic osteotomies were performed on ten cadaver pelves with pubic remnants equal to 0, 25, and 50% of the hemi-pubic length and angles of acetabular rotation of 20, 30, and 40 degrees. All combinations of pubic remnant lengths and angles of acetabular rotation caused a significant reduction in pelvic canal-width and cross-sectional area, when compared to the inact pelvis. Zero, 25, and 50% pubic remnants result in 15, 35, and 50% reductions in pelvic canal width respectively. Overrotation of the acetabulum should be avoided and the pubic remnant on the acetabular segment should be minimized to reduce postoperative complications due to pelvic canal narrowing.When performing triple pelvic osteotomies, the length of the pubic remnant on the acetabular segment and the angle of acetabular rotation both significantly narrow the pelvic canal. To reduce post-operative complications, due to narrowing of the pelvic canal, overrotation of the acetabulum should be avoided and the length of the pubic remnant should be minimized.

The paper presents solutions to the direct and inverse problems on longitudinal vibrations of a rod with a variable cross-sectional area. The law of variation of the cross-sectional area is modeled as an exponential function of a polynomial of degree n . The method for reconstructing this function is based on representing the fundamental system of solutions of the direct problem in the form of a Maclaurin series in the variables x and λ. Examples of solutions for various section functions and various boundary conditions are given. It is shown that to recover n unknown coefficients of a polynomial, n eigenvalues are required, and the solution is dual. An unambiguous solution was obtained only for the case of elastic fixation at one of the rod’s ends. The numerical estimation of the method error was made using input data noise. It is shown that the error in finding the variable crosssectional area is less than 1% with the error in the eigenvalues of longitudinal vibrations not exceeding 0.0001.
