We describe a case of left homolateral complete cleft lip/palate associated with a congenital left maxillary teratoma and left orbital teratoma. The patient required step-by-step reconstruction that first included resection of the 2 teratomas in consideration of cleft lip repair, cleft palate repair, and correction of the left periorbital anomalies, which were performed later. After performing all the necessary procedures, complete resection of the tumors and correction of the anomalies associated with the lip, palate, and left orbit were achieved...

Olfactory neuroblastoma (ONB) is a rare malignant neoplasm of the sinonasal tract that arises from olfactory epithelium. There have been reports, mainly in tumors treated with chemoradiation or with distant metastases, describing focal histologic changes of divergent cell populations within archetypal ONB. Only three cases have been reported of ONB coexisting with non-neuroendocrine tumors. We describe our experience with a 35-year-old male with a nasal cavity mass extending into the anterior cranial fossa...

Malignancies of the paranasal sinuses and ventral skull base present unique challenges to physicians. A transfacial or craniofacial approach allows for wide, possibly en bloc resection and is ideal for tumors that involve surrounding soft tissue, the palate, the orbit, anterolateral frontal sinus, and lateral dura. Transfacial approaches include a lateral rhinotomy often combined with a medial, subtotal, or total maxillectomy. Reconstruction is most commonly performed with a pericranial flap to separate the intranasal and intracranial compartments...

Klippel-Feil syndrome (KFS) is associated with numerous craniofacial abnormalities but rarely with skull base tumor formation. We report an unusual and dramatic case of a symptomatic, mature skull base teratoma in an adult patient with KFS, with extension through the basisphenoid to obstruct the nasopharynx. This benign lesion was associated with midline palatal and cerebral defects, most notably pituitary and vertebrobasilar arteriolar duplications. A multidisciplinary workup and a complete endoscopic, transnasal surgical approach between otolaryngology and neurosurgery were undertaken...

INTRODUCTION: Lesions affecting the anterior skull base represent a rare group of craniofacial pathologies. A tumor of the facial midline, meningitis, or rhinoliquorrhea may be indicative of malformations like dermoid cysts, gliomas, encephaloceles, or nasal fistulas. METHODS: We present a case series of 13 children (4 months to 12 years; 8 males, 5 females) with lesions involving the anterior skull base, which were treated surgically in an interdisciplinary setting...

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: 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...

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...

OBJECTIVE: Craniofacial bone trauma is a leading reason for surgery at most hospitals. Large pieces of destroyed or resected bone are often replaced with non-resorbable and stock implants, and these are associated with a variety of problems. This paper explores the use of a novel fatty acid/calcium phosphate suspension melt for simple additive manufacturing of ceramic tricalcium phosphate implants. METHODS: A wide variety of non-aqueous liquids were tested to determine the formulation of a storable 3D printable tricalcium phosphate suspension ink, and only fatty acid-based inks were found to work...

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...

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...

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...
