Long-Term Clinical Outcomes in Patients with Chronic Rhinosinusitis with Nasal Polyps Associated with Expanded Types of Endoscopic Sinus Surgery.

(1) Background: Surgical criteria for chronic rhinosinusitis with nasal polyps (CRSwNP) remain unresolved. This study addresses these discrepancies by comparing the clinical outcomes of expanded-functional endoscopic sinus surgeries (E-FESS) with more-limited FESS (L-FESS). (2) Methods: A database was analyzed retrospectively to compare surgical outcomes in CRSwNP patients who underwent E-FESS versus those subjected to L-FESS. Quality of life, endoscopic and radiological outcomes were compared at the baseline and two years after surgery. The clinical status of the responder was defined when a minimal clinically important difference of 12 points in SNOT-22 change was achieved. (3) Results: A total of 274 patients met the inclusion criteria and were analyzed; 111 underwent E-FESS and 163 were subjected to L-FESS. Both groups exhibited significant clinical improvements, although a greater magnitude of change in SNOT-22 (14.8 ± 4.8, p = 0.002) was shown after E-FESS. Higher significant improvements for endoscopic and radiological scores and lower surgical revision rates were also noted in the E-FESS group. (4) Conclusions: E-FESS provides better clinical outcomes and reduced revision surgery rates when compared to L-FESS in CRSwNP patients two years after surgery, irrespective of any comorbidity. Further randomized prospective studies are needed to comprehensively contrast these results.

International consensus recommendations on face transplantation: A 2-step Delphi study.

Face transplantation is a viable reconstructive approach for severe craniofacial defects. Despite the evolution witnessed in the field, ethical aspects, clinical and psychosocial implications, public perception, and economic sustainability remain the subject of debate and unanswered questions. Furthermore, poor data reporting and sharing, the absence of standardized metrics for outcome evaluation, and the lack of consensus definitions of success and failure have hampered the development of a "transplantation culture" on a global scale. We completed a 2-round online modified Delphi process with 35 international face transplant stakeholders, including surgeons, clinicians, psychologists, psychiatrists, ethicists, policymakers, and researchers, with a representation of 10 of the 19 face transplant teams that had already performed the procedure and 73% of face transplants. Themes addressed included patient assessment and selection, indications, social support networks, clinical framework, surgical considerations, data on patient progress and outcomes, definitions of success and failure, public image and perception, and financial sustainability. The presented recommendations are the product of a shared commitment of face transplant teams to foster the development of face transplantation and are aimed at providing a gold standard of practice and policy.

Application of Facial Artery Perforator Flap in Nasal and Perinasal Reconstruction.

This paper reports the results of an observational study in 23 patients to evaluate the application of the facial artery perforator flap in nasal and perinasal reconstruction after skin cancer surgery. In the long term, all flaps survived, and the patients achieved satisfactory esthetic reconstruction without functional alterations or major complications. Immediately postoperatively, 2 flaps presented early venous congestion, and 1 had minor superficial skin necrosis that healed without additional intervention. In 3 cases, it was combined with a second simultaneous local flap for synchronous or extensive skin tumors. The facial artery perforator flap is a reliable and versatile option that can be considered the preferred alternative for single-stage restorations of complex small to medium-sized nasal and perinasal defects that allow reconstruction of both external and internal nasal structures.

Silencing of AJAP1 expression by promoter methylation activates the Wnt/ß-catenin signaling pathway to promote tumor proliferation and metastasis in salivary adenoid cystic carcinoma.

Background: Salivary adenoid cystic carcinoma (SACC) is a unique malignant tumor of the salivary gland with poor prognosis, which is not effective with chemotherapy and targeted drugs. Therefore, it is important to explore the molecular mechanism underlying SACC invasion and metastasis to develop novel therapeutic strategies and targets in clinical research. Methods: Real-time quantitative polymerase chain reaction (RT-qPCR) and western blot (WB) were performed to detect the expression of Adherens Junctions Associated Protein 1 (AJAP1). Methylation-specific PCR was used to evaluate the methylation of the AJAP1 promoter. AJAP1 was overexpressed or knocked down by lentivirus-mediated transfection. Kaplan-Meier analysis was conducted to create a survival curve and the log-rank test was used to analyze the overall survival (OS). The prognostic correlation was assessed using univariate and multivariate Cox regression analyses. Co-immunoprecipitation (Co-IP) was utilized to pull down the possible binding protein of AJAP1 and laser scanning confocal microscopy was applied to detect the subcellular localization of AJAP1, E-cadherin, and ß-catenin. Cell viability, colony formation, wound healing, and Transwell invasion assays were performed to evaluate the function of AJAP1 in vitro. A subcutaneous xenograft assay in nude mice was performed to verify the function of AJAP1 in vivo. Results: AJAP1 was downregulated in SACC tumors and was closely related to SACC lymph node/distant metastasis, which was an independent risk factor for SACC prognosis. Methylation-specific PCR confirmed that high methylation of the AJAP1 promoter was the main cause of its silencing. Overexpression or knockdown of AJAP1 in SACC cells could significantly inhibit or promote the proliferation, invasion, and metastasis of SACC cells, respectively, in both the in vitro and in vivo experiments. Mechanically, we found that AJAP1 binds to E-cadherin and ß-catenin to form a complex in cytomembrane, reducing the nuclear translocation of ß-catenin and blocking the Wingless/Integrated/ß-catenin (Wnt/ß-catenin) signaling pathway to play a suppressive role in cancer. Conclusions: In conclusion, these results suggest that the downregulation of AJAP1 protein expression may play a certain role in progression and metastasis of SACC. Our study indicates that AJAP1 may be a potential prognostic molecular marker and therapeutic target for SACC.

Total Joint Replacement for Immediate Reconstruction following Ablative Surgery for Primary Tumors of the Temporo-Mandibular Joint.

Temporomandibular joint (TMJ) tumors are rare and difficult to diagnose. The purpose of this retrospective study was to evaluate the clinicopathologic characteristics of twenty-one patients with primary TMJ tumors between 2010 and 2019 and to analyze the surgical outcome and morbidity after ablative surgery and TMJ replacement. This case series confirmed the difficulty of diagnosis and reaffirmed the need for early recognition and management of TMJ tumors. There were no pathognomonic findings associated with TMJ tumors, although single or multiple radiopaque or radiolucent areas were observed on plain or panoramic radiographs. Occasionally, bone resorption or mottled densities caused by pathologic calcification and ossification were seen. Computed tomography and magnetic resonance imaging played an important role in the diagnosis. In our study, the distribution of histologic types of TMJ tumors was quite different from that of other joint tumors. The recommended treatment was surgical intervention by ablation of the joint and TMJ replacement. The results of this retrospective study support the surgical exeresis and replacement with TMJ stock and custom-made prostheses and show that the approach is efficacious and safe, reduces pain and improves mandibular movements, with few complications.

Surgical ciliated cyst of the maxilla after orthognathic surgery: A case report.

Surgical ciliated cysts are rare benign cystic lesions that generally occur a number of years after invasive surgical procedures or trauma involving the maxilla. The appearance of this cyst after orthognathic surgery is a complication that has rarely been reported. It usually shows as a well-defined radiolucency in the maxilla in young adults mimicking other maxillary cysts. Therefore, an exhaustive clinical-radiological diagnosis is needed to establish its differential diagnosis and appropriate treatment. The present study describes the case of a surgical ciliated cyst that appeared 20 years after LeFort I orthognathic surgery. Treatment consisted of complete enucleation with primary closure and removal of osteosynthesis material. Histopathological examination confirmed the diagnosis of a maxillary cyst lined with pseudostratified ciliated columnar cells. Clinicians should be aware of this rare type of cyst in patients with a history of maxillary surgery or trauma to establish a differential diagnosis and ensure appropriate management.

Botulinum Toxin and Percutaneous Needle Electrolysis for the Treatment of Chronic Masticatory Myalgia.

Botulinum toxin type A (BTA) is applied in muscle hyperactivity disorders and injected into affected muscles, producing deep and persistent muscle relaxation. Several multidisciplinary groups investigated the treatment of temporomandibular disorders for several years, and there is currently some data on the beneficial effects of BTA in specific cases of chronic masticatory myalgia. Percutaneous needle electrolysis (PNE), which applies a low-intensity galvanic current to promote tissue regeneration, has been shown to be effective in reducing pain and improving masticatory function. The purpose of this study was to investigate the efficacy and safety of BTA and to assess whether its application in patients with localized masticatory myalgia can significantly reduce pain and improve function compared to a group treated with PNE. Fifty-two patients with long-term refractory masticatory myalgia were randomly assigned to two groups. The BTA group (n = 26) received a bilateral botulinum toxin injection and the PNE group (n = 26) received percutaneous electrolysis. The dose of BTA injected was 100 units distributed among the main primary masticatory muscles, and PNE was administered at 0.5 mA/3 s/3 consecutive times in a single session. Patient assessments were performed prior to treatment and one, two, and three months after treatment. The results revealed good therapeutic response in both groups. In the long term, both BTA and PNE showed high efficacy and safety in reducing pain and improving muscle function for the treatment of chronic masticatory myalgia. This improvement was sustained over a three-month period in both groups. Therefore, the use of BTA and PNE could be considered a valid and safe therapeutic alternative among the available options to treat refractory and localized masticatory myalgia when a better therapeutic response is expected as it demonstrated high efficacy.

Estimated projection of oral cavity and oropharyngeal cancer deaths in Spain to 2044.

BACKGROUND: Oral cavity cancer (OCC) and oropharyngeal cancer (OPC) are two common malignancies whose mortality is worryingly increasing worldwide. However, few studies have estimated the mortality trends for these cancers in the coming years. This study analysed the mortality rates for OCC and OPC observed between 1980 and 2019 to generate a predictive model for the next 25 years in Spain. METHODS: Mid-year population data and death certificates for the period 1980-2019 were obtained from the Spanish National Institute of Statistics. The Nordpred program (Norwegian Cancer Registry, Oslo, Norway) was used to calculate adjusted mortality rates as well as estimated mortality projections with an age-period-cohort model for the period 2020-2044. RESULTS: The specific mortality rate per 100,000 inhabitants for OCC decreased from 2.36 (1980-1984) to 2.17 (2015-2019) and is expected to decline to 1.68 (2040-2044), particularly in males. For OPC, mortality rates rose from 0.67 (1980-1984) to 1.23 (2015-2019) and are projected to drop to 0.71 (2040-2044). In the group of females > 65 years predictions showed rising mortality rates for both OCC and OPC. The predictive model projects more deaths in females than in males for OCC in the period 2040-2044, while deaths for OPC will decrease in males and gradually increase in females. CONCLUSIONS: Although OCC mortality rates have been found to decrease in males in the last observed decades, there is still room to improve them in females > 65 years in the future by promoting campaigns against smoking and alcohol consumption. OPC mortality will become a growing health problem. Vaccination campaigns for the prevention of human papillomavirus-associated cancers may have a long-term impact on the mortality of these cancers, which should be evaluated in upcoming studies. CLINICAL RELEVANCE: Our findings highlighted the importance of closely monitoring OCC and OPC mortality rates in the coming years by age group and sex, and the need to continue preventive measures against the main known risk factors, such as tobacco, alcohol, and human papillomavirus infection.

Impact of the coronavirus pandemic on maxillofacial trauma: A retrospective study in southern Spain

Background: The coronavirus pandemic has impacted health systems worldwide, with Spain being one of the most affected countries. However, little is known about the extent to which the effects of staying home, social distancing, and quarantine measures have influenced the epidemiology of patients with maxillofacial trauma. The aim of this study was to analyze the impact of the coronavirus pandemic on the incidence, demographic patterns, and characteristics of maxillofacial fractures in the largest hospital in southern Spain. Material and Methods: Data from patients who underwent surgery for maxillofacial fractures during the first year of the pandemic between 16 March 2020 and 14 March 2021 (pandemic group) were retrospectively compared with a control group during the equivalent period of the previous year (pre-pandemic group). The incidence was compared by weeks and by lockdown periods of the population. Demographic information, aetioloy, fracture characteristics, treatment performed, and days of preoperative stay were evaluated. Descriptive and bivariate statistics were calculated (p<0.05). Results: During the first year of the pandemic, there was a 35.2% reduction in maxillofacial fractures (n=59) compared to the pre-pandemic year (n=91, p=0.040). A significant drop was detected during the total home lockdown period of the population (p=0.028). In the pandemic group, there was a reduction in fractures due to interpersonal aggressions, an increase in panfacial fractures, a significant increase in other non-facial injuries associated with polytrauma (p=0.037), a higher number of open reduction procedures with internal fixation, and a significantly longer mean preoperative stay (p=0.016). Conclusions: The first pandemic year was associated with a decline in the frequency of maxillofacial trauma and a change in the pattern and characteristics of fractures. Inter-annual epidemiological knowledge of maxillofacial fractures may be useful for more efficient planning of resource allocation and surgical practice strategy during future coronavirus outbreaks and population lockdowns.(AU)

Neurotrophic Keratitis in a Pediatric Patient With Goldenhar Syndrome and Trigeminal Aplasia Successfully Treated by Corneal Neurotization.

Herein, the authors report an unusual case of a 6-year-old boy with right-sided Goldenhar syndrome and trigeminal nerve aplasia who developed neurotrophic keratopathy (NK). Despite the use of therapeutic contact lenses and multiple temporary tarsorrhaphy, NK worsened showing a central corneal scar, neovascularization, and significant stromal thinning, with risk of corneal perforation. Cochet-Bonnet esthesiometry revealed complete corneal anesthesia. To minimize additional corneal complications, the patient underwent indirect corneal neurotization by a sural nerve autograft anastomosed to the contralateral supratrochlear nerve. At 24-month follow up, no epithelial defects, complications, or recurrence were observed. Significant improvements in corneal sensitivity with esthesiometry score of 20 mm and reflex blinking were achieved. This case highlights corneal anesthesia should be suspected among Goldenhar syndrome ophthalmologic abnormalities and monitored before corneal changes become irreversible. Since corneal neurotization can successfully improve corneal sensation, it could be considered as an early therapeutic option to avoid refractory NK.

Trends in mortality rates for oral and oropharyngeal cancer in Spain, 1979-2018.

OBJECTIVE: To analyse mortality rate trends in Spain for oral cavity and oropharyngeal cancer (OCOPC) from 1979 to 2018, evaluating differences between oral cavity cancer (OCC) and oropharyngeal cancer (OPC). MATERIALS AND METHODS: Death certificates and mid-year population data were collected from the Spanish National Statistics Institute. Age-standardized mortality rates were calculated using the direct method. Joinpoint regressions were used to identify significant changes in mortality trends. Independent effects of age, period and cohort (APC) were estimated. RESULTS: A total of 52,057 deaths were registered from OCOPC, 38,988 from OCC and 13,069 from OPC between 1979 and 2018. While OCC mortality rates declined, OCOPC rates increased slightly and OPC significantly. OCC and OPC mortality reached their highest values between 1979 and 1992, when OCC rates began to decrease in males and OPC levelled off until 2018. Lip cancer suffered the highest drop. APC models showed a mortality increase in males and females from 40 to 45 and 50 to 55 years of age, respectively. CONCLUSIONS: Favourable OCC mortality trends was plausibly influenced by decreased tobacco/alcohol consumption, while OPC rise was probably associated with increased human papillomavirus infection. The importance of closely monitoring these cancers by age group, sex and location, and continuing with preventive measures against known risk factors, is highlighted.

Synchronous occurrence of IgG4-related sialadenitis and ductal carcinoma of the parotid gland: a case report.

Immunoglobulin G4-related disease (IgG4-RD) is a rare chronic systemic inflammatory pathology that poses a diagnostic challenge since it can simulate malignancy when it affects a salivary gland as a mass-like lesion. Here, the authors report an unusual clinical case of a 42-year-old man who presented with a painless, slow-growing swelling located in the right parotid gland with a 12-month evolution. Based on imaging tests and open biopsy, a diagnosis of chronic parotitis was presumed and oral methylprednisolone was prescribed. Due to poor response to medication, a total parotidectomy preserving the facial nerve was performed. The final pathology described a unilateral IgG4-related sialadenitis (IgG4-RS) in the parotid gland in combination with a poorly differentiated multifocal ductal carcinoma. The postoperative course was uneventful except for a temporary facial paresis (grade III according to the House-Brackmann classification system) that resolved completely within 5 months. There were no systemic manifestations on the whole-body 18F-FDG PET/CT. Adjuvant radiotherapy was administered without complications. Twenty-four months follow-up after surgery showed no recurrence or evidence of systemic involvement. This clinical report highlights the importance of considering the synchronous occurrence of a carcinoma underlying an isolated parotid gland mass in the context of IgG4-RS, especially if there is no response to prior steroid medication.

Donor-recipient matching in hand transplantation: a comparison of anthropometric measurements, 3-dimensional virtual models and printed epitheses.

Donor-recipient matching in hand transplantation remains challenging. The usefulness of three-dimensional (3-D) virtual models and printed epitheses were compared with measurements on cadaveric extremities to evaluate the most accurate method of donor-recipient matching for allograft procurement. Ten anthropometric measurements were recorded from 12 human cadaveric upper extremities and matched to printed epitheses and 3-D virtual models. Five circumferential and two longitudinal measurements obtained an intra-class correlation of >0.75 with all three methods, with the Kaplan (0.973) and wrist circumferences (0.942) achieving the highest concordance. Measurement on cadaveric specimens was the most reliable method. Using different combinations of donor hand and recipient forearms, a series of 72 virtual transplantations were then created, and their compatibility rated by ten transplant surgeons. The results confirmed that anthropometric measurements, obtained directly from potential human donor limbs and based on wrist circumference as the primary parameter, provide the best and most clinically relevant donor-recipient match.

Quality of life in early age Spanish children treated for cleft lip and/or palate: a case-control study approach.

OBJECTIVE: The objectives of this study were to evaluate health-related quality of life (HRQoL) in 4-7-year-old children treated for cleft lip and/or palate (CL/P) compared to healthy controls and to estimate a possible association with cleft type, gender, age, and surgical re-interventions. MATERIALS AND METHODS: A total of 171 children with CL/P (mean age 5.7 years) and 186 healthy controls (mean age 5.5 years) were included in the study. Sixty-four (37.4%) children experienced both cleft lip and palate, 56 (32.8%) cleft lip only, and 51 (29.8%) cleft palate only. HRQoL in children was assessed by Kiddy-KINDL and COHIP-14 questionnaires and in parents by KINDL-p. Total score and dimensions of each questionnaire were compared between cleft children, their parents, and controls. RESULTS: The total scores and dimension scores of Kiddy-KINDL showed similar values between CL/P and control groups, except for "self-esteem" dimension (p = 0.036). The comparison of Kiddy-KINDL and KINDL-p showed a statistically significant total score (82.11 vs. 80.44, p = 0.047). The CL/P group presented significantly worse values with respect to controls in total score of COHIP-14 (10.53 vs 5.01, p < 0.001) and in all its dimensions. CONCLUSIONS: Children treated for CL/P had a negative impact on HRQoL at early age compared to controls. Significant differences were found in the psychological and functional dimensions related to lip and palatal affectation, respectively. Parents reported significantly worse scores than their children. HRQoL measurement provided valuable complementary information to better inform to parents and make clinical decisions in children with CL/P at early age. CLINICAL RELEVANCE: Our findings suggested that Spanish children between 4 and 7 years of age with a history of surgically treated CL/P experienced a poorer HRQoL when compared with their non-cleft peers.

Treatment of Localized and Referred Masticatory Myofascial Pain with Botulinum Toxin Injection.

Botulinum toxin type A (BTA) injection is considered an available alternative treatment for myofascial pain. However, its efficacy in treating masticatory myofascial pain syndrome (MMPS) remains unclear. The purpose of this study was to evaluate whether the BTA injection into the affected muscles would significantly reduce pain and improve function, and to assess its efficacy, safety, and therapeutic indications in a randomized, single-center clinical trial. Sixty patients with MMPS were randomized into three groups evenly to receive a single session injection of saline solution (SS group), lidocaine (LD group), and BTA (BTA group) in the masseter, temporal, and pterygoid muscles after an electromyographic study. Patients' pain was classified as localized or referred according to the DC/TMD classification. Assessments were performed on pre-treatment, and subsequently, on days 7, 14, 28, 60, 90, and 180. A significant reduction in pain and improvement of mandibular movements was found in the BTA group compared to the SS and LD groups. The response lasted until day 180 and was more intense in patients with localized myalgia and focused myofascial pain than in referred remote pain. No significant adverse reactions were observed. A single BTA injection can be considered an effective treatment option in patients with localized MMPS by reducing pain and improving mandibular movements, which persisted up to 6 months.

Oral health-related quality of life after dental treatment in patients with intellectual disability

BACKGROUND: The influence of dental treatment on oral health-related quality of life (OHRQOL) has rarely been evaluated in patients with intellectual disability (ID) through validated questionnaires. The aim of this study was to estimate the changes on OHRQOL in patients with ID after the implementation of an institutional dental treatment program under general anesthesia using the Franciscan Hospital for Children Oral Health-Related Quality of Life questionnaire (FHCOHRQOL-Q). MATERIAL AND METHODS: A prospective longitudinal study was conducted on 85 patients (mean age=24.85 years) classified according to DSM-V whose parents/caregivers completed the FHC-OHRQOL-Q. We analyzed the changes in the questionnaire's overall score and its dimensions from pre-treatment to 12-months of follow-up, considering effect sizes and minimal important differences estimated by the standard measurement error. The impact of clinical and therapeutic factors was evaluated using univariate and multiple linear regression analysis (p < 0.05). RESULTS: Significant improvement of OHRQOL was found after dental treatment in oral symptoms (p ≤ 0.001), daily life problems (p = 0.018), parent's perceptions (p = 0.013) and FHCOHRQOL-Q's overall score (p = 0.001). OHRQOL changes exhibited an intermediate magnitude (0.38-0.21) as estimated by effect sizes. Changes in oral symptoms showed positive correlation with DMFT index (r = 0.375, p = 0.002), decayed teeth (r = 0.244, p = 0.036), dental extractions (r = 0.424, p < 0.001) and number of treatments (r = 0.255, p = 0.019). The improvement was greater in patients with ≥ 4 decayed teeth (p = 0.049) and undergoing ≥ 2 dental extractions (p = 0.002). Multiple regression analysis demonstrated that dental extractions (p < 0.001) and DMFT index ( p= 0.028) were significantly related to oral symptom improvement. CONCLUSIONS: Dental treatment under general anesthesia showed a positive effect on the overall FHC-OHRQOL-Q score and most of its dimensions. At 12-months of follow-up, the improvement of oral symptoms was significantly associated with DMFT index, decayed teeth, dental extractions and number of treatments. In our clinical setting, the implementation of a dental treatment program enhanced the OHRQOL of patients with ID

Impact of Early Reoperation on the Prognosis of Patients Operated on for Glioblastoma.

BACKGROUND: The prognosis for patients with glioblastoma depends particularly on the degree of tumor resection. Patients with tumor remnants in postsurgical magnetic resonance imaging (<72 hours) may benefit from early reoperation. We present our results concerning the impact on overall survival (OS) and progression-free survival (PFS) of reoperation in patients who have already undergone surgery for glioblastoma. METHODS: This study included all patients who had undergone surgery for glioblastoma with control magnetic resonance imaging, who received adjuvant therapy as per the Stupp protocol, with a minimum follow-up of 24 months. We recorded the number of complete resections, partial resections, and early reoperations. We determined the impact on OS and PFS of the early reoperations and the functional status. We considered complete resection when the volume of the residual tumor was 0 cm3. RESULTS: A total of 112 patients were diagnosed with glioblastoma between March 2014 and March 2017. The study included 58 patients who fulfilled all the inclusion criteria. Complete resection was achieved in 24 patients (41.4%) and partial resection in 34 (58.6%). Of these 34 patients, 11 (32.35%) underwent early reoperation. The final result was complete resection in 58.62% of the patients. In the patients who underwent reoperation, OS and PFS were 30.3 months and 16.6 months compared with 12.7 months and 6.75 months in those without reoperation (P = 0.013 and P = 0.012). The functional prognosis was similar between the 2 groups. CONCLUSIONS: Early reoperation in patients with residual tumor improved OS and PFS without increasing the number of complications compared with the patients who did not undergo reoperation.

Application of Human Amniotic Membrane in Temporomandibular Joint Osteoarthritis.

Human amniotic membrane (HAM) has recently been used as an interpositional material to prevent ankylosis or primary re-ankylosis after temporomandibular joint (TMJ) arthroplasty. Here, the authors describe an unusual case of a 32-year-old woman who presented with a noninflammatory degenerative osteoarthritis of the TMJ in which a HAM was placed following a high condylar arthroplasty and discectomy and show the clinicoradiological results. The procedure resulted in total pain relief and significant improvement in jaw movements. On the long-term follow-up computed tomography, complete remodeling of the glenoid fossa with formation of new ectopic bone was observed. While the application of a HAM can be an alternative procedure to prevent ankylosis when performing a discectomy and arthroplasty, this clinical report highlights the possibility that it can induce ectopic bone formation at this location.
