Correction of the Crooked Nose Using Custom-Made High-Density Porous Polyethylene Extended Spreader Grafts

Correction of the crooked or deviated nose, a complex cosmetic and functional problem, is a big challenge for the rhinoplasty surgeon. Although corrections using a wide range of surgical techniques to straighten the nose and maximize nasal function have been proposed, recurrence is very common because of cartilage memory and scar contracture. Therefore, to prevent recurrence and to maintain the correction of the septum, a permanent support that is stable and strong, with the ability to maintain its given shape after placement on one or both sides of the septum, is needed. For this purpose, the authors planned to use a pair of custom-made high-density porous polyethylene (HDPP) extended spreader grafts. In this study, the concept and technique of HDPP, composed of a nonresorbable alloplastic material for correction of the crooked nose, and the authors’ experience using it, are presented. Currently, HDPP is readily available on the market as a thin plain sheet (0.85 × 38 × 50 mm) that can be cut to an appropriate size for spreader grafts. Ingrowths of fibrous tissue inside and around HDPP stabilize the upper lateral cartilages and septum in their new corrected position and maintain the corrected/straightened position. This material was used in 20 patients with crooked noses (9 with C-type and 11 with S-type noses). During a mean follow-up period of 18 months (range, 8–30 months), there were no complications, recurrences, or extrusions. Functional evaluation was performed using a visual analog scale before surgery and 6 months after surgery. Patients were asked to score their nasal breathing on a scale ranging from 0 to 100. The mean preoperative value was 32.50% ± 11.18%, and the postoperative value was 88.75% ± 8.71%. In conclusion, the use of custom-made HDPP extended spreader grafts is a safe, effective, reliable, and permanent method for correction of the crooked nose. In the long term, the authors believe that custom-made HDPP extended spreader grafts provide functional recovery and increased strength against further trauma or forces of scar contracture, and have the ability to prevent recurrence attributable to cartilage memory.

Nasal trauma: Primary reconstruction with open rhinoplasty

Due to the prominent location of the nose, the most common facial traumas are nasal injuries. Although nasal traumas usually require staged intervention at a later period of time, in selected cases, primary reconstruction can be effective. A 20-year-old man who was referred from the emergency department with nasal trauma is presented. He reported a fall after feeling unsteady, which caused a direct nasal injury. Clinical examination revealed septal fracture with obstruction of the left nasal cavity and deformity of the nasal pyramid (inverted V deformity). The patient also had a complete dissection of the columella skin. Epistaxis was self-limited, and an open rhinoplasty procedure was decided because the trauma occurred 1 h before admission and there was no significant edema. Surgical intervention included septal reconstruction combined with restoration of the nasal pyramid and columella. One month later, the patient had patent nasal airways, and he was satisfied with the aesthetic result.     

Augmentation Rhinoplasty with a Combination of Triple Cartilage Grafts for Secondary Rhinoplasty in a Middle-Aged Population

Because of physiologic changes with advancing age as well as previously traumatized and then healed tissues, secondary rhinoplasty for a middle-aged patient is a challenging procedure. Depending on both factors, changes in the midvault can cause a functional airway disorder, and the nose also may need a complete correction for cosmetic purposes. To achieve aesthetic and functional outcomes, augmentation rhinoplasty using a combination of triple cartilage grafts, namely, spreader, columellar, and dorsal onlays, was performed for 12 patients. Sufficient nasal airways with satisfactory appearance were achieved for 11 of 12 patients. Only one patient had improved but still insufficient nasal function with a good aesthetic result. Augmentation rhinoplasty using a combination of triple cartilage grafts for middle-aged patients could be considered an effective procedure for improving the patient’s nasal airway and appearance.     

Increasing the Length of the Middle Crura for Better Tip Projection in Primary Rhinoplasty

Cartilage grafts have been a very popular method for achieving tip projection in difficult noses. Sometimes asymmetries and graft visibility are undesirable complications. Remodeling the alar cartilages, using a cartilage flap from the lateral crura, rotated over the original domes, is another alternative for achieving tip refinement and projection. The surgical technique is described and clinical results are presented.

RETRACTED ARTICLE: A Different Approach to the Reconstruction of the Stubborn Crooked Nose with a Different Spreader Graft: Nasal Bone Grafts Harvested from the Removed Nasal Hump

Background Correction of a crooked or deviated nose is a complex cosmetic and functional problem as well as a big challenge for the rhinoplasty surgeon. Although corrections using a wide range of surgical techniques to straighten the nose and maximize nasal function have been proposed, recurrence is very common because of cartilage memory and scar contracture. Therefore, to prevent recurrence and maintain the correction of the septum, a permanent support that is stable and strong with the ability to maintain its given shape after placement on one or both sides of the septum is needed. Methods The author used a nasal bone graft. In this study, the concept and technique for correction of the crooked nose and the author’s experience using it are presented. Results This graft material was used for 12 patients with crooked noses (8 with C-type and 4 with S-type noses). During a mean follow-up period of 20 months (range, 12–36 months), there were no complications, recurrences, or extrusions. Functional evaluations were performed using a visual analog scale before surgery and 6 months after surgery. Patients were asked to score their nasal breathing on a scale ranging from 0 to 100. The mean preoperative value was 17.67% ± 1.22% (range, 15–25%), and the postoperative value was 89.88% ± 1.24% (range, 85–95%). Conclusion Use of nasal bone grafts as the spreader graft is a safe, effective, reliable, and permanent method for correction of the crooked nose. The author advises using this technique with nasal bone grafts for functional recovery and increased strength against further trauma or forces of scar contracture. This technique may prevent recurrence attributable to cartilage memory.     

A Simple Method Using a PACS to Minimize Leg Length Discrepancy in Primary THA : A Method to Minimize Leg Length Discrepancy

We determined whether a PACS-based method (head-lesser trochanter distance [HLD]) better equalized leg length discrepancy (LLD) after primary THA than a conventional method. We retrospectively reviewed 312 patients (379 hips) with osteonecrosis or primary osteoarthritis who underwent primary cementless THA: 198 patients (240 hips) underwent THA using the HLD method, while the conventional group consisted of 114 patients (139 hips) in whom we measured with the method of McGee and Scott. We then compared the LLDs in the two groups. We observed no difference in the mean postoperative LLD. A higher percentage of patients in the HLD group had an LLD less than 6 mm: 81% vs 68% hips, respectively. HLD method decreases the possibility of an LLD over 6 mm after THA.     

Primary umbilical endometriosis: A painful swelling in the umbilicus concomitantly with menstruation

BackgroundPrimary umblikal endometriosis is a rare illness. In this report we aimed to discuss the management of this rare condition.Case summaryA 28-year-old nulliparous woman was present at our clinic who was suffering from painful swelling in the umbilicus during her menstruation for the last 3 months. Her examination showed a dark-color sensitive nodule of 20 × 15 mm in size in the umbilicus. A lower abdominal tomography was performed to exclude the presence of a concomitant pelvic endometriosis, and it showed increased density consistent with subcutaneous inflammation in the umbilicus. Her medical history and physical examination suggested primary umbilical endometriosis. A total resection including umbilicus was performed.DiscussionPrimary umbilical endometriosis is a rare benign disease and clinically difficult to differentiate from other diseases that cause umbilical nodule. Imaging modalities have no pathognomonic findings for diagnosis. Surgical exploration and excision are the definitive and safe treatment of primary umbilical endometriosis.ConclusionTotal umbilical resection should be preferred to avoid local recurrent.     

Clinical Outcome of Surgical Hip Dislocation Combined with Impacting Bone Grafts and Implanting Iliac Bone Flaps in the Treatment of Osteonecrosis of the Femoral Head: A Mid‐term Retrospective Study

ObjectiveTo report the medium‐term outcomes of surgical hip dislocation (SHD) combined with impacting bone grafts and implanting iliac bone flaps in the treatment of osteonecrosis of the femoral head (ONFH) and to define the indications for this treatment.MethodsThis was a single‐center retrospective study. In total, 64 patients (70 hips) with ONFH treated from January 2014 to December 2017 were included in this study. There were 51 males and 13 females aged 18–55 years with an average age of 32 years. All patients underwent surgery for SHD combined with impacting bone grafts and implanting iliac bone flaps. Preoperative and postoperative clinical outcomes were assessed. The clinical outcome was assessed using the Harris hip score (HHS) and the conversion rate of total hip arthroplasty (THA). Univariate and multivariate logistic regression analyses were performed to identify risk factors affecting the clinical outcome. Kaplan–Meier (K‐M) analysis was applied to calculate the survival rate of the femoral head.ResultsAt the last follow‐up (60 ± 15.08 months), the HHS was excellent for 41 hips, good for 17 hips, fair for three hips, and poor for nine hips. All nine hips with poor HHS underwent THA, including five in the first 2 years following the index surgery and four between three and 5 years. The conversion rate of total hip arthroplasty was 12.86%. Univariate and multivariate logistic regression analyses showed that the duration of hip pain and JIC classification type were significantly associated with clinical outcomes. Elderly age and advanced ONFH stage tended to lead to worse surgical outcomes. The overall survival rate of JIC classification type C1 and duration of pain ≤6 months was 98.1% and 97.8% at 72 months, respectively, as estimated by the Kaplan–Meier method.ConclusionSurgical hip dislocation combined with impacting bone grafts and implanting iliac bone flaps in the treatment of ONFH had a good mid‐term clinical outcome, especially for patients with retention of the lateral column of the femoral head and hip pain less than 1 year.     

Minimum 7‐year Follow‐up of A Porous Coated Trabecular Titanium Cup Manufactured with Electron Beam Melting Technique in Primary Total Hip Arthroplasty

ObjectivesTo investigate the cup survivorship, patient satisfaction level, clinical function, and radiographic outcomes of patients who underwent total hip arthroplasty (THA) using electron beam melting (EBM)‐produced porous coated titanium cups at mid‐term follow up.MethodsA total of 32 patients (32 hips) from five hospitals in China who underwent primary THA using EBM‐produced trabecular titanium cups between May and December 2012 were retrospectively reviewed. The inclusion criteria were: (i) patients who underwent THA with the use of EBM‐produced cups with possible 7‐year follow up; and (ii) patients with follow‐up information, including the cup survivorship, patient satisfaction level, and clinical outcomes such as Harris hip score. The exclusion criteria were: (i) patients with neuropathic diseases; and (ii) patients who underwent THA due to neoplastic disease. Five (15.6%) patients were lost to follow up before the 7‐year follow‐up and, thus, were excluded; none of these patients died due to disease associated with the THA or had undergone removal of their cups as of our last evaluation. The mean age and body mass index of the patients were 59.37 (range: 38.00–69.00) years and 24.51 (range: 16.50–34.10) kg/m², respectively. Thirteen (48.1%) of the patients were female.ResultsThe average duration of follow‐up was 93.48 (range: 89.00–99.00) months. The median Harris hip score improved from 42.00 (interquartile range: 37.00–49.00) to 97.00 (interquartile range: 92.00–97.00) at the latest follow up (P < 0.001). A total of 18 (66.7%) patients rated their satisfaction level as very satisfied, 6 (22.2%) as satisfied, 2 (7.4%) as neutral and 1 (3.7%) as dissatisfied. No intraoperative or postoperative complications were identified. At the latest follow up, all cups were considered to have achieved osteointegration fixation, with three or more of the five signs evident in the most recent X‐ray. However, three cups revealed radiolucent lines with a width of less than 1 mm. The median vertical and horizontal distances between the latest postoperative center of rotation relative to the anatomic center of rotation were 2.50 (interquartile range: −3.10, 6.94) mm superiorly and 3.26 (interquartile range: −8.12, 2.38) mm medially, respectively, at the most recent postoperative follow up. Kaplan–Meier survivorship analysis of cups, with the endpoint defined as postoperative radiolucent lines of less than 1 mm in width in at least two zones, reveals that the 8.25‐year survival was 96.3% (95% confidence interval: 76.49%–99.47%).ConclusionThe mid‐term follow‐up of patients who underwent primary THA using EBM‐produced porous coated titanium cups demonstrated favorable patient satisfaction, good clinical function, excellent survivorship, and adequate biological fixation.     

Postoperative outcomes in older surgical patients with preoperative cognitive impairment: A systematic review and meta-analysis

Study objectiveTo determine the effect of cognitive impairment (CI) and dementia on adverse outcomes in older surgical patients.DesignA systematic review and meta-analysis of observational studies and randomized controlled trials (RCTs). Various databases were searched from their inception dates to March 8, 2021.SettingPreoperative assessment.PatientsOlder patients (≥ 60 years) undergoing non-cardiac surgery.MeasurementsOutcomes included postoperative delirium, mortality, discharge to assisted care, 30-day readmissions, postoperative complications, and length of hospital stay. Effect sizes were calculated as Odds Ratio (OR) and Mean Difference (MD) based on random effect model analysis. The quality of included studies was assessed using the Cochrane Risk Bias Tool for RCTs and Newcastle-Ottawa Scale for observational cohort studies.ResultsFifty-three studies (196,491 patients) were included. Preoperative CI was associated with a significant risk of delirium in older patients after non-cardiac surgery (25.1% vs. 10.3%; OR: 3.84; 95%CI: 2.35, 6.26; I²: 76%; p < 0.00001). Cognitive impairment (26.2% vs. 13.2%; OR: 2.28; 95%CI: 1.39, 3.74; I²: 73%; p = 0.001) and dementia (41.6% vs. 25.5%; OR: 1.96; 95%CI: 1.34, 2.88; I²: 99%; p = 0.0006) significantly increased risk for 1-year mortality. In patients with CI, there was an increased risk of discharge to assisted care (44.7% vs. 38.3%; OR 1.74; 95%CI: 1.05, 2.89, p = 0.03), 30-day readmissions (14.3% vs. 10.8%; OR: 1.36; 95%CI: 1.00, 1.84, p = 0.05), and postoperative complications (40.7% vs. 18.8%; OR: 1.85; 95%CI: 1.37, 2.49; p < 0.0001).ConclusionsPreoperative CI in older surgical patients significantly increases risk of delirium, 1-year mortality, discharge to assisted care, 30-day readmission, and postoperative complications. Dementia increases the risk of 1-year mortality. Cognitive screening in the preoperative assessment for older surgical patients may be helpful for risk stratification so that appropriate management can be implemented to mitigate adverse postoperative outcomes.
