BACKGROUND: Olfactory neuroblastoma is a rare sinonasal malignancy, with poorly defined treatment protocols. Management at a tertiary centre was retrospectively evaluated to inform future treatment and follow up. METHODS: Cases treated with curative intent (2000-2014) were included. Data were collected, and overall and disease-free survival rates were calculated. RESULTS: Eleven cases were identified, with a median follow up of 87 months. One patient was Kadish stage A, one was stage B, eight were stage C and one was stage D...

High-grade craniofacial osteosarcoma (CFOS) is an aggressive malignancy with a poor prognosis. Our goals were to evaluate treatment outcomes in those treated at a single referral institution over 35 years and to compare our results to the available literature. A retrospective analysis of all 42 patients treated between 1980 and 2015 at Oslo University Hospital, Norway, identified in a prospectively collected database, was conducted. Mean follow-up was 79.6 months. Overall survival at 2 and 5 years was 70...

BACKGROUND: Craniomaxillofacial reconstruction with patient-specific, customized craniofacial implants (CCIs) is ideal for skeletal defects involving areas of aesthetic concern-the non-weight-bearing facial skeleton, temporal skull, and/or frontal-forehead region. Results to date are superior to a variety of "off-the-shelf" materials, but require a protocol computed tomography scan and preexisting defect for computer-assisted design/computer-assisted manufacturing of the CCI. The authors developed a craniomaxillofacial surgical assistance workstation to address these challenges and intraoperatively guide CCI modification for an unknown defect size/shape...

Hemangiopericytomas are soft tissue tumors composed of pericytic cells that are characterized by their "staghorn" vascular branching and their variable clinical presentation. Fifteen to 25% of all HPC occur in the head and neck, with only 5% found in the nose or paranasal sinuses. Sinonasal hemangiopericytoma (SNHPC) is considered distinct from its soft tissue counterpart - the former showing a more uniform cellular organization, has convincing pericytic differentiation and is associated with a far better prognosis...

Osteosarcoma in the craniofacial region is rare. A 43-year-old female, the patient, self-detected a 3-cm tumor of the right frontoparietal region 4 months before. An incisional biopsy was performed and a osteosarcoma was reported. At admission, a 4 × 5 cm tumor was present on the right frontoparietal region, without extending to the orbital region but the patient underwent surgery 2 months after admission. The delay was due to 2 episodes of upper respiratory tract infection that required resolution. At the time of surgery the tumor measured 8 × 9 cm...

BACKGROUND: Surgical resection of ocular malignancies can result in complex craniofacial defects that can be difficult to reconstruct with conventional reconstruction techniques. Craniofacial prosthesis supported by bone-anchored implants has evolved as a reliable alternative in such scenarios. METHODS: The authors describe a patient who underwent extensive facial resection secondary to squamous cell carcinoma resulting in significant facial deformities. A bone-anchored osseointegrated implant was used to perform facial reconstruction...

Arteriovenous malformations are uncommon congenital disorders in vascular development. They frequently involve craniofacial structures and result in a morphogenic abnormality with ominous arteriovenous shunting. We present a huge AVM of the upper lip in an 18-year-old patient who was successfully treated by the combination method of presurgical endovascular embolization and complete resection of the lesion. Subsequent surgical defect in upper lip, which involved more than two-third of the lip length, was reconstructed via Webster's modification of cheek advancement flap...

INTRODUCTION: Fibrous dysplasia (FD) is a non-neoplastic developmental fibro-osseous disease. It represents 2.5% of all bone tumors and 5% to 7% of the benign bone tumors. Orbitocranial region is involved in about 20% of the patients. The main presentations are craniofacial deformity and headache. Loss of vision is the most devastating result of this disease. There is no medical treatment to cure or prevent FD. Radiation therapy is contraindicated. Surgery for the orbitocranial FD is often challenging because of the proximity of neurovascular and ocular structures...

BACKGROUND: Olfactory neuroblastoma (ONB) is an uncommon neoplasm that arises from olfactory epithelium in the nasal cavity near the cribriform plate. Although local recurrence or direct extension along olfactory epithelium and metastasis to the central nervous system has been reported, remote leptomeningeal metastasis is quite rare. In our report of a leptomeningeal metastasis of ONB without recurrence of primary site, we discuss the possible pathogenesis of this rare phenomenon with a review of the literature...

Osteoma is a benign, mesenchymal, slow-growing, osteogenic tumor commonly occurring in the craniofacial bones and is characterized by the proliferation of compact or cancellous bone. Solitary osteomas can be classified as peripheral (parosteal, periosteal, or exophytic) when arising from the periosteum or central (endosteal) when arising from soft tissue. Peripheral osteoma occurs most frequently in the paranasal sinuses. Other locations include the orbital wall, temporal bone, pterygoid processes, external ear canal, and, rarely, the mandible...

BACKGROUND: The gold standard of treatment for esthesioneuroblastoma consists of en bloc craniofacial resection with postoperative therapy dictated by histology and tumor extent. Numerous studies have shown fully endoscopic approaches to provide comparable survival and recurrence rates with decreased patient morbidity. Here we report the first multi-institutional series assessing smell outcomes of patients who underwent unilateral endoscopic resection of esthesioneuroblastoma with preservation of the contralateral olfactory bulb...

Leiomyosarcoma (LMS) is a malignancy which very rarely occurs in maxillofacial location, and the course of the disease is not very characteristic.In this case report, we present a 58-year-old female patient with a painless tumor of the left angle of the mandible causing slight asymmetry of the face. She also reported that she observed deterioration in fitting of the lower denture in the oral cavity for several months, which she had used successfully for 5 years.On the basis of clinical tests, histopatological examination, and imaging (CT, MRI, ultrasound, pantomography), the patient was diagnosed with primary malignant leiomyosarcoma (LMS) of the mandibular corpus and ramus on the left side...

Sinonasal malignancies are rare and histologically heterogeneous. Treatment is complicated by tumor aggressiveness and location near critical anatomic structures (orbita, skull base, etc.). This low incidence and histologic diversity make prospective studies unfeasible, and thus therapeutic guidelines difficult to establish. The gold standard for surgery is a transfacial approach, with craniofacial resection in case of skull-base involvement. However, these techniques are associated with non-negligible perioperative morbidity...

BACKGROUND: The subcranial approach is a modification of traditional craniofacial resection. It provides similar broad access to the anterior skull base, but with lower mortality and morbidity. It has been the surgical technique of choice at our institution since 2006 for treating advanced stage sinonasal tumours (American Joint Committee on Cancer stage III or above). This paper reports our experience and outcomes. METHOD AND RESULTS: Eighteen patients underwent subcranial craniofacial resection over a seven-year period, this being combined with a second adjunctive procedure in 89 per cent of cases...

Esthesioneuroblastoma is a rare tumor arising from the olfactory mucosa of upper respiratory tract. The primary modality of treatment has been surgery with craniofacial resection followed by post-operative radiotherapy. There are only a few reported cases of non-surgical approaches. We report a case of esthesioneuroblastoma with intracranial extension treated with Vincristine, Adriamycin, Cyclophosphamide, Ifosfamide, Etoposide protocol followed by radiation with 5 years of follow-up. This is the first reported case using this chemotherapy schedule...
