Reconstruction of congenital pseudarthrosis of the radius with a vascularized tibial periosteal transplant: A case report.

Congenital pseudarthrosis of the forearm poses a considerable challenge because of its rarity. The objective of this report is to introduce a novel surgical technique for its treatment. Here, we document a case of congenital pseudarthrosis of the radius in a 3-year-old boy diagnosed with type-1 neurofibromatosis. The surgical treatment involved the excision of approximately 9 cm of native radial periosteum and a bifocal radius osteotomy, which was supplemented with a vascularized tibial periosteal transplant to facilitate bone healing. Anastomosis between the anterior tibial vessels and radial vessels was performed. No immediate or late postoperative complications were observed. After 3 weeks, a robust callus formation was observed, and during a follow-up examination 3 years and 4 months later, a wide range of active forearm rotation was noted. This report suggests that vascularized periosteal flaps show promise as a viable treatment option for congenital pseudarthrosis of the forearm. They offer an alternative to vascularized fibular grafts or single-bone forearm constructs.

Periosteal wrapping of the hamstring tendon autograft improves graft healing and prevents tunnel widening after anterior cruciate ligament anatomic reconstruction.

INTRODUCTION: The periosteum is a readily available tissue at the hamstring harvest site that could be utilized to enhance graft healing and prevent tunnel widening without additional cost or morbidity. This study aimed to compare graft healing using magnetic resonance imaging (MRI) and functional clinical outcome scores in a matched cohort of patients who underwent anterior cruciate ligament (ACL) reconstruction with hamstring autografts with or without periosteal augmentation. MATERIAL AND METHODS: Forty-eight patients who underwent ACL reconstruction (ACLR) were prospectively enrolled: 25 with standard ACLR (ST-ACLR) and 23 with periosteal augmented grafts (PA-ACLR). The same surgical techniques, fixation methods, and postoperative protocol were used in both groups. Signal-to-noise quotient (SNQ), graft healing at the bone-graft interface, graft signal according to the Howell scale, and femoral tunnel widening were evaluated using MRI after 1 year of follow-up. International knee documentation score (IKDC), Lysholm, Tegner activity scale, and visual analog scale for pain were used for functional evaluation at a minimum of 2 years postoperative. RESULTS: The mean SNQ of the proximal part of the graft was 9.6 ± 9.2 and 2.9 ± 3.3 for the ST-ACLR and PA-ACLR groups, respectively (P = 0.005). The mean femoral tunnel widening was 30.3% ± 18.3 and 2.3% ± 9.9 for the ST-ACLR, PA-ACLR groups, respectively (P < 0.001). Complete graft tunnel healing was observed in 65% and 28% of cases in the PA-ACLR and ST-ACLR groups, respectively. Both groups showed marked improvements in functional scores, with no statistically significant differences. CONCLUSION: Periosteal wrapping of hamstring tendon autografts is associated with better graft healing and maturation and lower incidence of femoral tunnel widening based on MRI analysis 1 year after ACL reconstruction. However, patient-reported outcomes and measured laxity were similar between the two groups at 2 years follow up.

Versatility of the medial corticoperiosteal flap: from recalcitrant non-unions up to large bony defects.

BACKGROUND: Reconstructive microsurgery techniques using vascularized bone grafts have revolutionized the treatment of complex cases associated with recalcitrant non-unions or osteomyelitis. The medial femoral corticoperiosteal flap (MFCP flap) has emerged as a valuable option in bone reconstruction. Its clinical applications have been extended over the years considering this flap from non-unions with minimal bone lost, up to large intercalary defects of the upper and lower extremities. This article aims to present the clinical applications and outcomes of the MFCP flap in various reconstructive scenarios. METHODS: Seventy-nine patients with persistent non-union and bone defects of the upper and lower limb were evaluated from June 2008 to October 2020. All of them were reconstructed with a corticoperiosteal flap from the medial femoral condyle in our hospital. Previous procedures, bone gap and type of flap used were recorded. Postoperative functional status was assessed with time of bone healing, complications and clinical final outcome. RESULTS: Radiological evidence of bone union was observed at 4.09 months (range 2-9). Healing rate was 97% with periosteal corticocancellous flaps (PCC flaps) and 93% with corticoperiosteal flaps (CP flaps). Average follow-up was 14.5 months (range 5-28). There were no significant donor site complications. CONCLUSIONS: The MFCP flap offers a versatile and reliable option for bone reconstruction. Its ability to provide vascularized bone tissue with low morbidity enhances the healing process and improves outcomes. The MFCP flap has been increasing its applications and it serves as a valuable option in the treatment of recalcitrant non-unions or bony defects irrespective of site and size up to 5 cm in the upper and lower extremities.

Evaluation of the efficacy of autogenous tibial periosteal bone grafting in the treatment of osteochondral lesions of the talus and analysis of three-dimensional factors in the necrotic zone.

PURPOSE: This study aims to explore the clinical value of autogenous tibial periosteal bone grafting in the treatment of osteochondral lesions of the talus (OLT) and analyze the three-dimensional factors in the necrotic zone of the talus. METHODS: A retrospective analysis was performed on 36 patients who underwent autogenous tibial periosteal bone grafting in the Foot and Ankle Surgery Department of our hospital between September 2018 and September 2022. The American Orthopaedic Foot and Ankle Society (AOFAS), Visual Analogue Scale (VAS), and Chinese Short-Form 36 Health Survey (SF-36) were used to evaluate treatment efficacy prior to surgery and at the last follow-up. Furthermore, Mimics 21.0 software was employed to measure the three-dimensional data of the necrotic area, including surface area, volume, and depth, in order to investigate their potential impact on patient prognosis. RESULTS: Among the 36 OLT patients who obtained complete follow-up, there were 22 males and 14 females. No complications such as surgical site infection, non-union of cartilage, post-traumatic arthritis, or donor site pain were observed. The AOFAS, VAS, and Chinese SF-36 scores of all patients at the last follow-up showed significant improvement compared to preoperative values. There was no significant correlation between the AOFAS, VAS, and Chinese SF-36 scores at the last follow-up and the depth, surface area, and volume of the necrotic zone. CONCLUSION: The use of autogenous tibial periosteal bone grafting can safely and effectively treat Hepple V OLT. Additionally, there is no significant correlation between the three-dimensional factors of the necrotic area and the prognosis of the patients.

Ex Vivo Preservation of Ovine Periosteum Using a Perfusion Bioreactor System.

Periosteum is a highly vascularized membrane lining the surface of bones. It plays essential roles in bone repair following injury and reconstruction following invasive surgeries. To broaden the use of periosteum, including for augmenting in vitro bone engineering and/or in vivo bone repair, we have developed an ex vivo perfusion bioreactor system to maintain the cellular viability and metabolism of surgically resected periosteal flaps. Each specimen was placed in a 3D printed bioreactor connected to a peristaltic pump designed for the optimal flow rates of tissue perfusate. Nutrients and oxygen were perfused via the periosteal arteries to mimic physiological conditions. Biochemical assays and histological staining indicate component cell viability after perfusion for almost 4 weeks. Our work provides the proof-of-concept of ex vivo periosteum perfusion for long-term tissue preservation, paving the way for innovative bone engineering approaches that use autotransplanted periosteum to enhance in vivo bone repair.

Biosynthesized Bandages Carrying Magnesium Oxide Nanoparticles Induce Cortical Bone Formation by Modulating Endogenous Periosteal Cells.

Bone grafting is frequently conducted to treat bone defects caused by trauma and tumor removal, yet with significant medical and socioeconomic burdens. Space-occupying bone substitutes remain challenging in the control of osteointegration, and meanwhile activation of endogenous periosteal cells by using non-space-occupying implants to promote new bone formation becomes another therapeutic strategy. Here, we fabricated a magnesium-based artificial bandage with optimal micropatterns for activating periosteum-associated biomineralization. Collagen was self-assembled on the surface of magnesium oxide nanoparticles embedded electrospun fibrous membranes as a hierarchical bandage structure to facilitate the integration with periosteum in situ. After the implantation on the surface of cortical bone in vivo, magnesium ions were released to generate a pro-osteogenic immune microenvironment by activating the endogenous periosteal macrophages into M2 phenotype and, meanwhile, promote blood vessel formation and neurite outgrowth. In a cortical bone defect model, magnesium-based artificial bandage guided the surrounding newly formed bone tissue to cover the defected area. Taken together, our study suggests that the strategy of stimulating bone formation can be achieved with magnesium delivery to periosteum in situ and the proposed periosteal bandages act as a bioactive media for accelerating bone healing.

Congenital pseudarthrosis of the tibia: Rate of and time to bone union following contralateral vascularized periosteal tibial graft transplantation.

INTRODUCTION: Congenital pseudarthrosis of the tibia (CPT) is one of the most challenging orthopedic disorders. The use of a vascularized tibial periosteal grafts has been recently reported as a powerful tool to obtain bone union. We report its use in CPT. PATIENTS AND METHODS: Retrospective short-term study of 29 children (18 male/11 female, 15 right-sided/14 left-sided) of mean age 45 months (range 11-144 months), operated upon after October 2014. Nonunion site was debrided, and the periosteum of the involved limb was excised. A vascularized tibial periosteal graft (mean length 10.7 cm (range 9-15 cm) with a monitoring skin island (mean length 4.1 cm (range 3-5 cm) and based on the anterior tibial vessels, was obtained from the contralateral tibia. Anterior tibial vessels were always the recipient vessels. Most cases were stabilized with an LCP plate. The rate of and time to bone union were analyzed. Charts only were evaluated through the first 3 months after bone union was achieved. RESULTS: The flap survived and bone union was obtained in all cases, through a periosteal callus, in a mean time of 5.1 weeks (range 3-6 weeks). Mean follow-up was 8.3 months (range 7-19 months). No union failures occurred 3 months after resuming unprotected weight bearing. CONCLUSIONS: Our novel technique produced a consistent, rapid capacity for CPT union, superior to previously-reported techniques. However, it cannot be recommended as a standard method of treatment until consistent, long-term, refracture-free follow-up is documented.

Osteogenic Capacity of the Prefabricated Periosteofascial Flap using Vascular Induction with Skeletonized Pedicle Transfer in Rabbit Calvarium.

The study investigated the osteogenic capacity of a prefabricated periosteal flap created using only skeletonized pedicle transfer without fascia or muscle for vascular induction in rabbit calvarium. A critical-sized bone defect was made in the parietal bone centered on the sagittal suture, and the demineralized bone matrix was implanted. The periosteofascia over the defect was used as a form of prefabricated periosteofascial flap (PPF group, N=10), conventional periosteofascial flap (CPF group, N=10), and nonvascularized free periosteofascial graft (FPG group, N=6). The prefabricated flap was designed via vascular induction by transferring the central artery and vein of the right auricle onto the periosteofascia for 4 weeks prior to flap elevation. A quantitative comparison of volume restoration and radiodensity in the bone defect and a histological study were performed after 6 weeks of covering the bone defect with periosteofascia. The volume restoration of the bone defect covered with the PPF (43.4%) was not different from that of the CPF (46.2%), but significantly increased compared with that of the FPG (24.6%). The radiodensity of the bone defect covered with the PPF (-186.3 HU) was not different from that of the CPF (-153.6 HU), but significantly increased compared with that of the FPG (-329.8 HU). The results were based on adequate vascular development of the periosteum and were closely related to the osteogenic changes in the implanted demineralized bone matrix (DBM). In conclusion, even in the PPF created by transferring only skeletonized vascular pedicles, the osteogenic capacity of the periosteofascial flap is well maintained.

Repair of long bone defects of large size using a tissue-engineered periosteum in a rabbit model.

Tissue engineering is a promising approach for bone regeneration. In this study, we aimed to investigate whether tissue engineered periosteum (TEP), which was fabricated by combining osteogenically-induced mesenchymal stem cells (MSCs) with porcine small intestinal submucosa (SIS), could restore long bone defects of large size in rabbits. Twenty-four adult New Zealand white rabbits (NZWRs) were used in the experiments. Long bone defects of large size (30 mm-50 mm; average, 40 mm) were established on both sides of NZWRs' radii. The defects were treated with TEP (Group A), allogeneic deproteinized bone (DPB, Group B), TEP combined with DPB (Group C), and pure SIS (Group D). The healing outcome was evaluated by radiography and histological examination at 4, 8, and 12 weeks post-treatment. The radiographical findings showed that bone defects of large size were all repaired in Groups A, B and C within 12 weeks, whereas Group D (pure SIS group) failed to result in defect healing at 4, 8, and 12 weeks. Although there was some new bone regeneration connecting the allografts and bone ends, as observed under radiographical and histological observations, bone defects of large sizes were restored primarily by structurally allografted DPB within 12 weeks. The TEP groups (Groups A and C) showed partial or total bone regeneration upon histological inspection. Based on 12-week histological examinations, significantly more bone was formed in Group A than Group C (P < 0.05), and both groups formed significantly more bone than in Groups B and D. The results indicated that long bone defects of a large size could be restored by TEP or TEP combined with the DPB scaffold, and such materials provide an alternative approach to resolving pathological bone defects in clinical settings.

Septal Perforation Repair Using Bilateral Rotational Flaps With Interposed Mastoid Periosteal Graft.

OBJECTIVES/HYPOTHESIS: To evaluate the outcomes of endonasal repair of septal perforations utilizing opposing bilateral rotational flaps and a periosteum interposition graft. METHODS: Retrospective review of a single surgeon, tertiary referral center experience of patients who underwent septal perforation repair. Patient demographics, etiology of perforation, closure rate, and complication data were obtained. Patients screening positively for cocaine use or anti-neutrophil cytoplasmic antibodies (ANCA) were not offered repair. RESULTS: A total of 104 patients were included, 65 male and 39 female with mean age of 45.4 years. Etiology of perforations included prior surgery in 45, trauma in 15, and unknown in 44, and the average perforation size in each etiologic group were 1.35 cm, 1.25 cm, and 1.30 cm, respectively. The greatest dimension of perforations repaired ranged from 0.5 cm to 1.5 cm. The overall success rate was 87.5% at 6 month follow-up. Successful closure was achieved in 95.6%, 86.7%, and 79.5%, respectively (χ2  = 5.264, P = .0218). CONCLUSION: Our described technique is a reliable endonasal approach with predictable outcomes in septal perforations up to 1.5 cm in size. Having an unknown etiology of septal perforation may be a risk factor for failure. LEVEL OF EVIDENCE: 4 Laryngoscope, 131:1497-1500, 2021.

Extensor Retinaculum Flap and Fibular Periosteum Ligamentoplasty After Failed Surgery for Chronic Lateral Ankle Instability.

BACKGROUND: The anterior talofibular ligament and the calcaneofibular ligament are 2 of the most frequently injured structures in sports, being damaged in 30% to 45% of all sports injuries. Most reconstructive procedures are successful but can deteriorate with time and can lead to low-grade radiographic degeneration. METHODS: We operated on 26 consecutive patients from 2001 to 2008 who had failed previous surgical procedures for the lateral ligamentous complex of the ankle, with an average of 104 (range, 75-140) months. RESULTS: The overall functional rating was excellent in 14 ankles, good in 10, fair in 1, and poor in 1. Twenty-four patients (92.3%) were satisfied with the procedure and 15 (57.7%) were able to return to their preinjury level of activity. Local complications were detected in 2 patients who presented with skin necrosis; 1 patient developed severe reflex sympathetic dystrophy. CONCLUSION: Revision surgery for the management of failure after surgical treatment of chronic lateral ankle instability is under debate, and the literature is devoid of clinical studies with long-term follow-up. The technique described offers a high rate of long-term excellent and good results, with a low rate of complications and a good rate of return to preinjury level. LEVEL OF EVIDENCE: Level IV, retrospective case series.

Prospective Long-term Follow-up of Autologous Chondrocyte Implantation With Periosteum Versus Matrix-Associated Autologous Chondrocyte Implantation: A Randomized Clinical Trial.

BACKGROUND: Matrix-associated autologous chondrocyte implantation (MACI) is a further development of the original autologous chondrocyte implantation periosteal flap technique (ACI-P) for the treatment of articular cartilage defects. PURPOSE: We aimed to establish whether MACI or ACI-P provides superior long-term outcomes in terms of patient satisfaction, clinical assessment, and magnetic resonance imaging (MRI) evaluation. STUDY DESIGN: Randomized controlled trial; Level of evidence, 2. METHODS: A total of 21 patients with cartilage defects at the femoral condyle were randomized to MACI (n = 11) or ACI-P (n = 10) between the years 2004 and 2006. Patients were assessed for subjective International Knee Documentation Committee (IKDC) score, Lysholm and Gillquist score, Tegner Activity Score, and 36-Item Short Form Health Survey (SF-36) preoperatively (T0), at 1 and 2 years postoperatively (T1, T2), and at the final follow-up 8 to 11 years after surgery (T3). Onset of osteoarthritis was determined using the Kellgren-Lawrence score and Magnetic Resonance Observation of Cartilage Repair Tissue (MOCART) score, and delayed gadolinium-enhanced MRI of cartilage was used to evaluate the cartilage. Adverse events were recorded to assess safety. RESULTS: There were 16 patients (MACI, n = 9; ACI-P, n = 7) who were reassessed on average 9.6 years after surgery (76% follow-up rate). The Lysholm and Gillquist score improved in both groups after surgery and remained elevated but reached statistical significance only in ACI-P at T1 and T2. IKDC scores increased significantly at all postoperative evaluation time points in ACI-P. In MACI, IKDC scores showed a significant increase at T1 and T3 when compared with T0. In the majority of the patients (10/16; MACI, 5/9; ACI-P, 5/7) a complete defect filling was present at the final follow-up as shown by the MOCART score, and 1 patient in the ACI-P group displayed hypertrophy of the repair tissue, which represents 6% of the whole study group and 14.3% of the ACI-P group. Besides higher SF-36 vitality scores in ACI-P at T3, no significant differences were seen in clinical scores and MRI scores between the 2 methods at any time point. Revision rate was 33.3% in MACI and 28.6% in ACI-P at the last follow-up. CONCLUSION: Our long-term results suggest that first- and third-generation ACI methods are equally effective treatments for isolated full-thickness cartilage defects of the knee. With the number of participants available, no significant difference was noted between MACI and ACI-P at any time point. Interpretation of our data has to be performed with caution due to the small sample size, which was further limited by a loss to follow-up of 24%.

Free vascularized medial femoral condyle corticoperiosteal flap with non-vascularized iliac crest graft for the treatment of recalcitrant clavicle non-union.

Clavicle non-union is a challenging problem. Open reduction with internal fixation and autologous bone grafting is usually the first line treatment. In case of failure, the medial femoral condyle corticoperiosteal flap in association with a non-vascularized bone graft is one of the therapeutic options, which is well adapted to the clavicle anatomical characteristics. We performed a retrospective study of all patients treated with this technique in our department. Between 2014 and 2017, five patients with recalcitrant post traumatic clavicle non-unions received this surgical treatment. The average nonunion time period was 50.2 month (range 10 to 108 months), and the mean defect length was 3.4 cm (between 2 and 5 cm), defects were all located in the medial third of the clavicle Three patients achieved full consolidation with an average time of consolidation of 8,7 months (range 6 to12 months). Patients with radiological consolidation had better functional improvement and pain reduction with an average DASH score improved from 53,6 before surgery to 19,6 after consolidation (at the last follow up visit). There was one donor site complications (hematoma). The medial femoral condyle corticoperiosteal flap with non-vascularized iliac crest graft is a good option for the management of recalcitrant clavicle non-union, especially when the bone defect is small.

Effects of low-intensity pulsed ultrasound exposure on rats tibia periosteum.

The periosteum is a rich source of osteoprogenitor cells and periosteal grafts can be used as an alternative method to replace bone grafts. The low-intensity pulsed ultrasound (LIPUS) has often been used as a noninvasive method to stimulate osteogenesis and reduce the fracture healing time. The aim of this study was to evaluate the effects of the ultrasound exposure on the rat tibia periosteum. Group I (7 animals) received LIPUS therapy on the left tibia for 7 days and group II (7 animals) on the left tibia for 14 days. After euthanasia, the tibias were processed. Number of periosteal cells and vessels and thickness of the periosteum were analyzed. The number of periosteal cells was higher in stimulated periosteum compared to controls at 7 and 14 days, but the number of vessels and the thickness only were higher in the group stimulated at 14 days. Furthermore, the ultrasound treatment for 14 days was more effective than 7 days. The ultrasound stimulation of the periosteum prior to grafting procedure can be advantageous, since it increases periosteal activity, and LIPUS may be an alternative method for stimulating the periosteum when the use of periosteal grafts in bone repair is needed.

The medial femoral condyle free corticoperiosteal flap versus traditional bone graft for treatment of nonunions of long bones: a retrospective comparative cohort study.

Fracture healing is a complex process and many factors change the local biology of the fracture and reduce the physiologic repair process. Since 1991 the free vascularised corticoperiosteal graft has been proposed to treat nonunions. In this study we compare the healing rate and the healing time of the free vascularised corticoperiosteal graft harvested from medial femoral condyle versus the traditional cancellous bone graft from the iliac crest combined with other biologic or pharmacologic factors. We performed a retrospective cohort study. The main measures of outcomes were the rate of bone union and the mean healing time from surgery. The authors performed 10 free vascularised corticoperiosteal grafts in the cohort A and 10 patients received traditional cancellous bone graft plus other biologic or pharmacologic treatment in the same period in the cohort B. The mean follow up in cohort A was 18.6 months with a healing rate of 100% (10/10). In cohort B the mean follow up was 22.5 month with a healing rate of 90%. The mean time to obtain union (healing time) in the group that was treated with the free flap procedure was significantly shorter, 3.2 months versus a mean time of 8.8 months in the other group. Some studies describe a high healing rate of recalcitrant nonunions with treatments different from vascularized bone flaps: it is difficult to compare the results of vascularized bone transfers with the results of other case series. Our groups are very homogeneous even if it is difficult to define correct inclusion criteria because there is still no agreement about what is defined a recalcitrant or difficult nonunion, and the number of trials of previous surgery before to perform a vascularized free flap. Even if our study cohort is small, we have demonstrated that the MFCCF generally seems to give a better healing chance with a shorter healing time compared to other treatments.

Floppy eyelid syndrome "plasty" procedure: Employment of a periosteal transposition flap for surgery of floppy eyelid syndrome.

IMPORTANCE: Floppy eyelid syndrome "plasty" (FESplasty) is a surgical technique that addresses underlying superior tarsal plate and lateral canthal instability in floppy eyelid syndrome (FES) and aims to restore normal anatomical and physiological function to the upper eyelid. BACKGROUND: To describe the use of FESplasty in the surgical management of FES, and to report outcomes in an initial patient cohort. DESIGN: Retrospective study. PARTICIPANTS: Seven patients (nine eyelids) with FES undergoing FESplasty. METHODS: A single surgeon (G.W.) performed all procedures. FESplasty utilizes a periosteal flap based at the inferolateral orbital rim, and applied to the anterior surface of the upper tarsal plate. It is combined with a titrated shortening procedure of the upper eyelid. Patient demographics, comorbidities and ocular symptoms and signs were recorded preoperatively. Pre- and postoperative upper eyelid distractibility were graded and documented. MAIN OUTCOME MEASURES: Postoperative improvement in upper eyelid distractibility and symptomatology, operative complications and FES recurrence. RESULTS: FES symptoms and upper eyelid laxity improved at last follow-up (average 24 weeks) in all patients, with no FES recurrences after a maximum follow-up of 36 weeks. One patient, in whom FESplasty exacerbated his pre-existing aponeurotic ptosis, required definitive ptosis surgery subsequently. There was one case of postoperative wound infection. Obstructive sleep apnoea was present in four of the seven patients. The remaining three patients were awaiting assessment. CONCLUSIONS AND RELEVANCE: FESplasty is likely to confer long-term effective stabilization of the lateral canthal tendon, lateral commissure and superior tarsal plate. Anatomical and functional results appeared to have been successfully achieved.

Use of Mastoid Periosteum Graft in Primary and Revision Rhinoplasty.

BACKGROUND: The authors initiated the use of a mastoid periosteum graft to augment or camouflage the dorsum and radix. This report describes the techniques and treatment outcomes of mastoid periosteum grafts in primary and revision rhinoplasty. MATERIALS AND METHODS: Medical records of 62 patients who underwent rhinoplasty with mastoid periosteum were reviewed retrospectively. Of these, 21 patients who participated in follow-up for more than 6 months were analyzed through a comparison of pre- and postoperative photographs. Aesthetic results were scored on a scale of 0 to 4 (0 = poor, 1 = fair, 2 = moderate, 3 = good, 4 = excellent) with photographic evaluation by two independent surgeons. RESULTS: A mastoid periosteum graft was used in 32 primary and 30 revision cases. The graft was used to augment the radix (28 cases), dorsum (15 cases), and both radix and dorsum (19 cases). Cartilage underlay was combined with mastoid periosteum grafts in 38 patients (61.3%, 17 in radix graft, 8 in dorsal graft, and 13 in both). The aesthetic outcome score assessed in 21 patients was 2.8 on average (3.2 in primary and 2.4 in revision cases). Cartilage combined cases showed better aesthetic outcome than free graft cases (3.1 vs. 2.5, respectively). Three cases of partial graft resorption were found, but there were no major complications. CONCLUSIONS: Mastoid periosteum grafting is a safe and effective method to augment the radix or dorsum in primary and revision rhinoplasty. Long-term partial resorption cannot be completely excluded, which necessitates further study. LEVEL OF EVIDENCE IV: This journal requires that authors assign a level of evidence to each article.
