Cranioplasty Outcomes From 500 Consecutive Neuroplastic Surgery Patients.

BACKGROUND: Cranioplasty is critical to cerebral protection and restoring intracranial physiology, yet this procedure is fraught with a high risk of complications. The field of neuroplastic surgery was created to improve skull and scalp reconstruction outcomes in adult neurosurgical patients, with the hypothesis that a multidisciplinary team approach could help decrease complications. OBJECTIVE: To determine outcomes from a cohort of cranioplasty surgeries performed by a neuroplastic surgery team using a consistent surgical technique and approach. METHODS: The authors reviewed 500 consecutive adult neuroplastic surgery cranioplasties that were performed between January 2012 and September 2020. Data were abstracted from a prospectively maintained database. Univariate analysis was performed to determine association between demographic, medical, and surgical factors and odds of revision surgery. RESULTS: Patients were followed for an average of 24 months. Overall, there was a reoperation rate of 15.2% (n = 76), with the most frequent complications being infection (7.8%, n = 39), epidural hematoma (2.2%, n = 11), and wound dehiscence (1.8%, n = 9). New onset seizures occurred in 6 (1.2%) patients.Several variables were associated with increased odds of revision surgery, including lower body mass ratio, 2 or more cranial surgeries, presence of hydrocephalus shunts, scalp tissue defects, large-sized skull defect, and autologous bone flaps. importantly, implants with embedded neurotechnology were not associated with increased odds of reoperation. CONCLUSIONS: These results allow for comparison of multiple factors that impact risk of complications after cranioplasty and lay the foundation for development of a cranioplasty risk stratification scheme. Further research in neuroplastic surgery is warranted to examine how designated centers concentrating on adult neuro-cranial reconstruction and multidisciplinary collaboration may lead to improved cranioplasty outcomes and decreased risks of complications in neurosurgical patients.

Postextraction Mucormycosis in Immunocompromised-Patient Management and Review of Literature.

PURPOSE: Mucormycosis is an uncommon aggressive, opportunistic infection that can produce widespread orofacial tissue necrosis. This primarily affects immunocompromised individuals. It is the deadliest and most rapidly progressing type of human-affecting fungal infection. The aim of the study is to investigate the diagnostic criteria and treatment approach in 10 cases of mucormycosis in the author's institute from 2008 to 2019. Moreover, a review of the English literature presents all cases of mucormycosis after tooth extraction. MATERIALS AND METHODS: Ten patients at our institute have been treated. They were evaluated and discussed as per their diagnostic criteria, surgical treatment, and mortality rates. RESULTS: All 10 immunocompromised patients had a primary hematologic malignancy. The criteria for a positive diagnosis were clinical symptoms and a biopsy for microbiological culture and histologic analysis. Each patient was subjected to vigorous surgical resection and underwent antifungal treatment. Seven patients died because of their main disease. Owing to the unregulated spread of mucormycosis, 2 patients died. Four cases were diagnosed after maxillary tooth extraction. CONCLUSIONS: The most important factor for patient survival tends to be the management of the underlying disease with early detection and active surgical and antifungal action. Four of 10 cases diagnosed with mucormycosis appeared after tooth extraction, a relatively high number compared with the literature. Therefore, it is the dental profession's obligation to be familiar with the possibility of the potentially severe and possibly fatal complication.

Management of Pediatric Orbital Fractures.

INTRODUCTION: Although uncommon in children, orbital fractures can be devastating to both vision and appearance. Due to the scarce information in the literature, the authors here present our experience and management with all pediatric orbital fracture patients. MATERIAL AND METHODS: A 6-years retrospective study was conducted on pediatric patients presented with orbital wall fracture (OFx). All patients (n = 43) were grouped for comparison based on the treatment method. The cohorts were analyzed for demographics data, location of fracture, type of material used for reconstruction, complication rate and follow up length. Data was analyzed utilizing SPSS for χ2 test. RESULTS: The majority of patients were male (86%) and the mean age of patients was 12.09 ±â€Š4 years. Mean follow-up time was 237 ±â€Š72 days. Most of Patients 31 (72%) underwent surgical intervention. A higher rate of complications was observed in the surgically treated group (32%) compared to the conservative group (8%) regardless to the defect size. Subgroup analysis of the surgery treated group revealed that large size defect had inferior outcome compared to small size defect. CONCLUSION: The consequences of treatment on long-term growth and development must be a cornerstone when choosing the optimal therapeutic method. Conservative management should be considered first in the absence of significant clinical pathologies. In addition, when surgery is indicated the least invasive procedure should be applied. The use of autogenous bone graft is preferable over alloplastic materials, however, when there is insufficient bone quantity the use of alloplastic materials is not contraindicated for reconstruction.

Risk of Complications in Primary Versus Revision-Type Cranioplasty.

INTRODUCTION: Cranioplasty (CP) is a multifaceted procedure in a heterogenous patient population, with a high risk for complication. However, no previous large-scale studies have compared outcomes in primary (ie, first attempt) CP versus revision CP (ie, following previous attempts). The authors, therefore, analyzed long-term outcomes of 506 consecutive primary and revision CPs, performed by a single surgeon. METHODS: All CPs performed between 2012 and 2019 were analyzed under IRB protocol approval. Surgeries were categorized as either primary (no previous CP; n = 279) or revision CP (at least one previous CP; n = 227). Complications were defined as either major or minor. Subgroup analyses investigated whether or not CP complication risk directly correlated with the number of previous neuro-cranial surgeries and/or CP attempts. RESULTS: The primary CP group experienced a major complication rate of 9% (26/279). In comparison, the revision CP group demonstrated a major complication rate of 32% (73/227). For the revision CP group, the rate of major complications rose with each additional surgery, from 4% (1 prior surgery) to 17% (2 prior surgeries) to 39% (3-4 prior surgeries) to 47% (≥5 prior surgeries). CONCLUSION: In a review of 506 consecutive cases, patients undergoing revision CP had a 3-fold increase in incidence of major complications, as compared to those undergoing primary CP. These results provide critical insight into overall CP risk stratification and may guide preoperative risk-benefit discussions. Furthermore, these findings may support a center-of-excellence care model, particularly for those patients with a history of previous neuro-cranial surgeries and/or CP attempts.

Bilateral Versus Unilateral Cranialization in the Management of a Breached Frontal Sinus.

BACKGROUND: Frontal sinus breach during craniotomy may occur inadvertently or intentionally. Management of a breached frontal sinus is controversial as numerous operative techniques have been described. Frontal sinus breach may result in life-threatening complications, require additional surgeries, and increase the risk for long-term infectious sequelae. A literature review found a paucity of neurosurgical reports examining breached frontal sinus management or specific analyses of unilateral versus bilateral frontal sinus cranialization. OBJECTIVE: A frontal sinus cranialization technique employed for patients involving frontal sinus breach and analyze outcomes managed with bilateral versus unilateral cranialization was presented in this study. METHODS: A retrospective review of outcomes was performed using our Institutional Review Board-approved surgical case database between September 2012 and September 2018. RESULTS: Thirty-three frontal sinus cranializations following frontal sinus breach were identified. Average follow-up time was 25 months. A statistically significant difference in postoperative infections was observed in patients with a history of previous cranial surgery who underwent unilateral compared to bilateral frontal sinus cranialization. CONCLUSION: These results suggest surgeons performing craniotomy or consulted intraoperatively for suspected frontal sinus breach should have a high suspicion for breached frontal sinus and a low threshold for frontal sinus cranialization. Furthermore, when performing frontal sinus cranialization, surgeons should consider performing bilateral, instead of unilateral, cranialization in patients with a history of previous craniotomy as bilateral cranialization was shown to decrease the risk of postoperative infection.

First-in-Human Experience With Integration of a Hydrocephalus Shunt Device Within a Customized Cranial Implant.

BACKGROUND: Implantable shunt devices are critical and life saving for hydrocephalus patients. However, these devices are fraught with high complication rates including scalp dehiscence, exposure, and extrusion. In fact, high shunt valve profiles are correlated with increased complications compared to those with lower profiles. As such, we sought a new method for integrating shunt valves for those challenging patients presenting with scalp-related complications. OBJECTIVE: To safely implant and integrate a hydrocephalus shunt valve device within a customized cranial implant, in an effort to limit its high-profile nature as a main contributor to shunt failure and scalp breakdown, and at the same time, improve patient satisfaction by preventing contour deformity. METHODS: A 64-yr-old male presented with an extruding hydrocephalus shunt valve and chronic, open scalp wound. The shunt valve was removed and temporary shunt externalization was performed. He received 2 wk of culture-directed antibiotics. Next, a contralateral craniectomy was performed allowing a new shunt valve system to be implanted within a low-profile, customized cranial implant. All efforts were made, at the patient's request, to decrease the high-profile nature of the shunt valve contributing to his most recent complication. RESULTS: First-in-human implantation was performed without complication. Postoperative shunt identification and programming was uncomplicated. The high-profile nature of the shunt valve was decreased by 87%. At 10 mo, the patient has experienced no complications and is extremely satisfied with his appearance. CONCLUSION: This first-in-human experience suggests that a high-profile hydrocephalus shunt device may be safely integrated within a customized cranial implant.

Full-Thickness Skin Grafting for Local Defect Coverage Following Scalp Adjacent Tissue Transfer in the Setting of Cranioplasty.

INTRODUCTION: Numerous techniques have been described to overcome scalp deficiency and high-tension closure at time of cranioplasty. However, there is an existing controversy, over when and if a free flap is needed during complex skull reconstruction (ie, cranioplasty). As such the authors present here our experience using full-thickness skin grafts (FTSGs) to cover local defects following scalp adjacent tissue transfer in the setting of cranioplasty. METHODS: By way of an institutional review board-approved database, the authors identified patients treated over a 3-year period spanning January 2015 to December 2017, who underwent scalp reconstruction using the technique presented here. Patient demographics, clinical characteristics, technical details, outcomes, and long-term follow up were statistically analyzed for the purpose of this study. RESULTS: Thirty-three patients, who underwent combined cranioplasty and scalp reconstruction using an FTSG for local donor site coverage, were identified. Twenty-five (75%) patients were considered to have "high complexity" scalp defects prior to reconstruction. Of them, 12 patients (36%) were large-sized and 20 (60%) medium-sized; 21 (64%) grafts were inset over vascularized muscle or pericranium while the remaining grafts were placed over bare calvarial bone. In total, the authors found 94% (31/33) success for all FTSGs in this cohort. Two of the skin grafts failed due to unsuccessful take. Owing to the high rate of success in this series, none of the patient's risk factors were found to correlate with graft failure. In addition, the success rate did not differ whether the graft was placed over bone verses over vascularized muscle/pericranium. CONCLUSION: In contrary to previous studies that have reported inconsistent success with full-thickness skin grafting in this setting, the authors present a simple technique with consistent results-as compared to other more complex reconstructive methods-even in the setting of highly complex scalp reconstruction and simultaneous cranioplasty.

Dural Reconstruction With Autologous Rectus Fascia: A New Technique for Addressing Large-Sized Defects During Cranioplasty.

INTRODUCTION: Patients requiring cranioplasty reconstruction with customized cranial implants may unexpectedly present with cerebrospinal fluid (CSF) leaks and durotomies following previous neurosurgical procedures. As such, multiple factors influence the type of dural reconstruction chosen at this time, which are essential for achieving long-term success. Overall, the most common material used for duraplasty is currently an "off-the-shelf" xenograft construct. However, some believe that they are not suitable for large-sized defects and accompany a higher incident of complications. Therefore, based on our success and experience with scalp augmentation using rectus fascia grafts, the authors herein present our preliminary experience with duraplasty using autologous rectus fascia grafts (ARFGs). METHODS: A retrospective review of our database, consisting of 437 cranial reconstructions from 2012 to 2017, was performed under institutional review board approval. Selection criteria included all adult patients (n = 6) requiring dural reconstruction (duraplasty) with ARF grafting for an active CFS leak with concomitant skull defect. Cadaver study and patient illustrations are also presented to demonstrate clinical applicability. All outcomes, including complications, were reviewed and are presented here. RESULTS: A total of 6 patients underwent autologous duraplasty with either unilateral or bilateral ARFGs. All patients (6/6) of large-sized (>3 cm) defect repair with ARFGs were indicated for repair of secondary CSF leaks following previous craniotomy by neurosurgery. To date, none have demonstrated recurrent leaking and/or dura-related complications. At this time, all 6 patients were reconstructed using customized cranial implants with a mean follow-up of 10 months. CONCLUSION: Based on our preliminary experience presented here, the use of rectus fascia grafts for autologous dural reconstruction appears to be both safe and reliable. This new technique adds another tool to the neurosurgical armamentarium by reducing the additional risk of "off-the-shelf" dural substitutes.

Introducing the Rectus Fascia Scalp Augmentation Technique: A New Method for Improving Scalp Durability in Cranioplasty Reconstruction.

OBJECTIVE: Patients with cranioplasty in need of skull reconstruction are at increased risk of complications when presenting with abnormally thin scalps. As such, the authors sought to develop and investigate a new technique for scalp augmentation using autologous rectus fascia grafts (ARFGs) for prevention of implant extrusion and long-term scalp durability. METHODS: A retrospective review of our database, consisting of 450 consecutive cranial reconstructions from 2012 to 2017, was performed under institutional review board approval. Selection criteria included all adult patients requiring implant-based cranioplasty reconstruction and concomitant scalp augmentation using ARFGs. All long-term outcomes were reviewed for scalp-related complications and are presented here. RESULTS: In total, 12 consecutive patients receiving ARFGs were identified. Average follow-up was 10 months (range = 2-17 months). Average graft size and dimension was 82 cm (range = 12-360 cm). All patients (n = 12) underwent concomitant cranioplasty reconstruction and had a history of at least 5 or greater previous neurocranial operations. Six patients had radiation therapy prior to cranioplasty. Two major complications (2/12, 17%) were identified related to deep, recurrent intracranial infections. More importantly, none of the patients (n = 12) in this study cohort developed scalp breakdown and/or implant extrusion in the areas of rectus fascia scalp augmentation. CONCLUSION: The use of ARFGs for underlay scalp augmentation appears to be both safe and reliable based on our preliminary experience. This new approach is extremely valuable when performing large-size cranioplasty reconstruction in patients with abnormally thin scalps, an extensive neurosurgical history, and/or suboptimal tissue quality. Furthermore, this method has been successful in avoiding free tissue transfer and/or staged tissue expansion as first-line surgery in our complicated cranioplasty population.

Post-Neurosurgical Temporal Deformities: Various Techniques for Correction and Associated Complications.

INTRODUCTION: An irregular craniofacial contour along the temporal fossa, known commonly as 'temporal hollowing deformity,' (THD) can arise from multiple etiologies. In fact, up to half of all patients who undergo neurosurgical pterional dissections develop some form of temporal contour deformities. Unfortunately, temporal hollowing correction remains surgically challenging with many techniques resulting in high rates of failure and/or morbidity. METHODS: Herein, we describe anatomy contributing to postsurgical temporal deformity as well as time-tested prevention and surgical correction techniques. In addition, a review of 25 articles summarizing various techniques and complication profiles associated with temporal hollowing correction are presented. RESULTS: Complications included infection, implant malposition, revision surgery, pain, and implant removal because of implant-related complications Augmentation with either autologous fat or dermal filler is associated with the highest number of reported complications, including catastrophic events such as stroke, pulmonary embolism, and death. No such complications were reported with use of alloplastic material, use of autologous bone, or free tissue transfer. Furthermore, careful attention to adequate temporalis muscle resuspension and position remain paramount for stable restoration of craniofacial symmetry. CONCLUSIONS: Catastrophic complications were associated with injection augmentation of both fat and dermal filler in the temporal region. In contrast, use of alloplastic materials was not found to be associated with any catastrophic complications. As such, for the most severe cases of THD, we prefer to employ alloplastic reconstruction.

Improving Postoperative Nasal Airway Patency in Le Fort-Based, Maxillofacial Trauma Patients Via a Modified Nasal Packing Technique.

INTRODUCTION: Combined mid-face and nasal apparatus trauma injuries pose a significant challenge to airway patency (AW), in the immediate postoperative setting following fracture reduction. As such, the authors describe a modified technique with the goal of maintaining a patent nasal AW, while at the same time, minimizing nasopharyngeal bleeding and nasal AW edema-which can complicate patients requiring intermaxillary fixation (IMF) in the setting of pan-facial trauma. METHODS: A modified technique was devised to assist the reconstruction surgeon in avoiding the risks associated with tracheostomy placement. In an effort to avoid surgical AW complications and improve nasal AW patency in the setting of concurrent IMF and nasal trauma, the authors developed a 2-stage technique drawing upon knowledge from the literature and the authors' own experiences. TECHNIQUE: Following safe extubation, the authors insert open lumen nasal splints in both the nostrils, and suture them together to the nasal septum. If additional inner nasal support is required, polyvinyl alcohol nonabsorbable nasal packing dressing is covered with antibiotic ointment, and then placed within the nasal cavity lateral to the open lumen splints-as a way to further bolster the internal valve and mid-vault anatomy. DISCUSSION: Given the fact that traditional nasal packing with merocele/gauze dressing in concomitant to IMF reduced patients ability to ventilate, the authors felt that a modified technique should be applied. The authors' preferred materials in such patients are open lumen splint, which provides nasal AW patency along with some septum support accompanied by merocele dressing. The authors feel that by applying this technique they achieve dual objectives by supporting the traumatized nose and maintaining nasal AW patency.

Adult Cranioplasty Reconstruction With Customized Cranial Implants: Preferred Technique, Timing, and Biomaterials.

INTRODUCTION: Complex cranial defects requiring delayed reconstruction present numerous challenges. Delayed cranioplasties accompany frequent complications approaching an incidence of 35 to 40%. Therefore, the authors sought to collate their experience in hopes of sharing their perspective on several topics including technique, timing, and preferred biomaterials. METHODS: The authors' 5-year consecutive experience over 430 customized cranial implants is described herein. Since its inception in 2012, the authors' team has employed the pericranial-onlay cranioplasty technique instead of the standard epidural approach. Optimal timing for cranioplasty is determined using objective criteria such as scalp healing and parenchymal edema, close collaboration with neuroplastic surgery, conversion from autologous bone to sterile implant in instances of questionable viability/storage, and the first-line use of solid poly(methylmethacrylate) implants for uncomplicated, delayed cases, first-line porous polyethylene (MEDPOR) implants for single-stage cranioplasty, and first-line polyether-ether-ketone implants for cases with short notice. Furthermore, the use of the pterional design algorithm with temporal bulking for all customized implants has helped to correct and/or prevent temporal hollowing deformities. RESULTS: The authors' team has observed a three-fold reduction in reported complications as compared with the existing literature, with a major complication rate of 11%. The multidisciplinary center has provided an optimal stage for synergy and improved outcomes versus standard cranioplasty techniques. CONCLUSION: Secondary cranial reconstruction, or cranioplasty, can be challenging due to numerous reasons. These best practices, developed in collaboration with neuroplastic surgery and neurosurgery, appear to encompass the largest published experience to date. The authors find this approach to be both safe and reliable.

Trend and Demographic Characteristics of Maxillofacial Fractures in Level I Trauma Center.

AIM: The aim of this study was to analyze the pattern and treatment of craniomaxillofacial injuries in the northern part of Israel, within a Jewish majority and large Arab minority population. PATIENTS AND METHODS: A 5-year retrospective study evaluated patients treated for craniomaxillofacial fractures. Fracture cause, type, site, and patient demographics were evaluated. RESULTS: Patient age ranged from 1 to 94 years with an average age of 36.7 years; 52% of the victims were Jews and 48% Arabs. There was male predilection in both sectors (78.3% vs 21.7%). The main site of injury was the zygomatic bone (33.5%) followed by nasal bone, orbital, mandible, frontal sinus, and maxillary fractures. The main etiology of injuries was falls (45.4%) with significantly more falls reported by females (52.1% vs 43.2% in males). Motor vehicle accidents caused injuries more frequent in males. Arabs experienced CMF fractures at a younger age compared to Jews (27.8 and 44.8 average age, respectively). In the elderly, the trend reversed where Jews were more prone to craniomaxillofacial fractures. CONCLUSIONS: Compared to their weight in the population, the Arab sector experiences more craniomaxillofacial injuries. The Jewish elderly population tends to reside in nursing homes where they are more susceptible to accidental falls, whereas young Arab males are more exposed to motor vehicle accidents and interpersonal violence. Falls were the main cause of injuries particularly in women. This may reflect the women's fear of reporting domestic violence. We believe that increased government investments in infrastructures and education will lower the incidence of craniomaxillofacial trauma and balance the gap between both sectors and sexes.

Functional Reconstruction in Mandibular Avulsion Injuries.

The present report describes the planning and surgery as well as pitfalls and management of a patient with a near total mandibular avulsion injury that was rehabilitated using three-dimensional (3D) laser printing of a titanium lower jaw. Laser-sintering involves zapping layers of powdered metal to recreate a 3D implantable skeletal defect. The process involves using either mirror imaging of the unaffected side or using archival image database of healthy individuals. A 25-year-old man presented with a gunshot injury that left him with a near total avulsed mandible. The patient received state-of-the-art treatment using a laser 3D printed mandible which was connected to the muscles of mastication for functionality. The inner side of the titanium jaw was filled with the patient's comminuted fractured bones in addition to harvested iliac crest bone graft that was covered with the patient's remaining periosteal tissue. The implantation of a near total mandible using 3D laser printing is a fast and predictable process that in selected patients can result in aesthetically as well as functionally excellent results. The authors believe that the future of craniofacial reconstruction will employ these methods for facial bony reconstruction.

Mandibular osteomyelitis associated with dental implants. A case series.

PURPOSE: To present a series of rare and serious complications associated with endosseous implant therapy. MATERIALS AND METHODS: Five cases of mandibular osteomyelitis emerging in dental implant insertion sites are presented. In three cases, the clinical signs and symptoms of osteomyelitis occurred almost immediately following implant insertion. All cases occurred in patients with stable pre-existing medical conditions. Three of the patients were females and two were males, all of whom were in their sixth and seventh decades of life. RESULTS: Clinical symptoms such as pain and local infection were observed in all cases, despite long-term antibiotic treatment. All cases underwent progressive surgical treatment including corticotomy, saucerization, sequestrectomy and drainage. Two cases exhibited spreading of bone infection in the mandible which required segmental mandibulectomy and fixation using reconstruction plates. The symptom-free state was only achieved following surgical intervention and antibiotic treatment in four patients. A minimal follow-up of 1 year revealed complete resolution of the infection and symptoms in four out of five patients. The outcome of the fifth patient is unknown. CONCLUSIONS: Osteomyelitis related to dental implants is a rare and serious complication. Prolonged antibiotics at high dosage together with aggressive surgical treatment is required. Increasing the awareness among dental surgeons and maintaining correct surgical principles are essential in order to reduce the risk of osteomyelitis. Conflict of interest statement: We have no conflict of interests to report.

Lymphoepithelial carcinoma--review of the treatment modalities and report of a rare case in the sublingual gland.

Controversies exist in the current literature regarding the treatment of lymphoepithelial carcinoma (LEC). The presented study summaries the literature controversies in the treatment of LEC and present a case of a rare LEC diagnosed in the sublingual gland of an otherwise healthy 21-year-old Arab woman. The patient was admitted for swelling in the sublingual area. A biopsy indicated a diagnosis of LEC of the sublingual gland. Treatment included a wide resection with safe margins, marginal mandibulectomy, functional neck dissection, and a radial forearm free flap for reconstruction. The patient received concomitant radiotherapy and has remained disease free since her last follow-up. The recommended primary treatment, based on the literature review, is primary surgical excision with neck dissection and optional adjuvant radiotherapy to the gland area. Chemotherapy was not found to be beneficial according to the literature.

Polymorphous low grade adenocarcinoma: case series and review of surgical management.

PURPOSE: The aim of the present study was to review the published data regarding the management of polymorphous low-grade adenocarcinoma (PLGA) and present our experience in the treatment of patients diagnosed with PLGA. MATERIALS AND METHODS: We performed a review of the published data of the treatment possibilities for PLGA, and report on a case series of 4 patients diagnosed with palatal PLGA. RESULTS: The mean age at diagnosis was 61.75 years. All cases were localized on the hard palate. The male/female ratio was 1:3. One patient had an ulcerative painful lump. In correlation with the published data, most of our patients presented initially with a diagnosis that was not conclusive for the presence of PLGA. The most common initial diagnostic findings were adenoid cystic carcinoma and pleomorphic adenoma. The treatment of choice was surgical excision of the tumor with safe margins of 1.5 cm. One patient had a positive cervical lymph node metastasis and underwent an elective neck dissection followed by radiotherapy. Local recurrence was diagnosed in 1 patient 6 years after the surgical management. Most cases were reconstructed using an obturator, except for 1 patient who underwent reconstruction using the temporalis myofascial flap. CONCLUSIONS: PLGA is a slow-growing, distinct, uncommon neoplasm of the minor salivary glands. Because it is characterized by a diverse morphologic pattern that resembles adenoid cystic carcinoma or pleomorphic adenoma, the initial diagnosis is usually inconclusive. Until a final diagnosis has been made, we believe that the reconstruction possibilities should be mainly obturators to allow a good visualization of the surgical site. The use of microvascular free flaps or rotational flaps should be reserved to patients with clearer pathologic diagnosis.
