PURPOSE: Resections in the posterior component of the oral cavity usually lead to severe functional compromise and lower quality of life for patients. Notable advances in reconstruction of the posterior part of the mouth and of the oropharynx have occurred in recent decades. The anatomic and physiologic rehabilitation of the defect to a reasonable outcome with low morbidity and mortality remains the founding basis of any surgical reconstruction, which also holds true for oral oropharyngeal and retromaxillary reconstructions...

Only four primary gliosarcoma case reports are described in the literature with transcranial (intradural to extradural) penetration into the region of the infratemporal fossa. This is the first report of a primary glioblastoma (GBM) that evolved into secondary or post-treatment gliosarcoma without evidence of a second de novo tumor and with extension into the left pterygomaxillary fossa.

Wisdom tooth operations are sometimes accompanied by complications. This case report shows complications during upper jaw third molar removal. Expectable problems during oral surgery should be planned to be solved in advance. Displacement of the third molar during oral surgeries as a considerable complication is rarely discussed scientifically. A good design of flap, adequate power for extraction, and clear view on the surgical field are crucial. Three-dimensional radiographic diagnostics in terms of cone beam computed tomography is helpful after tooth displacement into the infratemporal fossa...

Small cell neuroendocrine carcinoma (SNEC) is a rare form of malignancy. It mainly presents as bronchogenic neoplasm, and the extrapulmonary form accounts for only 0.1% to 0.4% of all cancers. These extrapulmonary tumors have been described most frequently in the urinary bladder, prostate, esophagus, stomach, colon and rectum, gall bladder, head and neck, cervix, and skin. Primary SNEC of the sinonasal tract is extremely rare with only less than 100 cases reported in the literature. Because of extreme rarity and aggressiveness of the tumor, the management for this entity varies considerably mandating multimodality approach...

BACKGROUND: Extirpation of tumors arising in the pterygopalatine fossa is challenging because of its anatomic complexity. METHODS AND RESULTS: A 67-year-old man was referred to our department with a diagnosis of a tumor in his left pterygoid fossa. An incisional biopsy through the canine fossa was diagnosed as myxofibrosarcoma. The upper part of the maxilla was swung laterally to remove the tumor while the hard plate was preserved. The defect was reconstructed using rectus abdominis musculocutaneous free and ipsilateral temporal...

BACKGROUND: Haemostatic agents including thrombin-based haemostatic matrix are widely used in patients undergoing cardiac, vascular and spinal surgery. These agents promote local haemostasis through activation of the clotting cascade. To our knowledge, this case series is the first report of pulmonary embolization associated with FloSeal following head and neck oncology resection and free flap reconstruction. METHODS: We present five patients who were diagnosed with symptomatic pulmonary embolism after oncologic head and neck free flap reconstructions in 2014 and 2015...

INTRODUCTION: Skull base meningoencephaloceles are rare congenital malformations. The two cases of transalar transsphenoidal malformation reported here differ from the classical transsphenoidal meningoencephalocele. CASE REPORTS: Case 1 was a three-and-a-half-year-old boy and case 2 was a 36-year-old man. Both cases presented with clinical features of recurrent meningitis. Surgical management of case 1 was performed via an intradural infratemporal fossa craniotomy with reoperation 2years later...

Understanding of morphological structures such as the sphenoid spine and pterygoid processes is important during lateral transzygomatic infratemporal fossa approach. In addition, osseous variations such as pterygospinous and pterygoalar bridges are significant in clinical practice because they can produce various neurological disturbances or block the passage of a needle into the trigeminal ganglion through the foramen ovale. Two hundred and eighty-four sides of Korean adult dry skulls were observed to carry out morphometric analysis of the lateral plate of the pterygoid process, to investigate, for the first time among Koreans, the incidence of the pterygospinous and pterygoalar bony bridges, to compare the results with those available for other regional populations, and to discuss their clinical relevance as described on literatures...

Recurrent invasive ameloblastoma of the infratemporal fossa is an uncommonly encountered phenomenon in the practice of oral and maxillofacial surgery and presents many surgical challenges for the practitioner. This case report describes a patient who underwent previous resection of a mandibular ameloblastoma with multiple recurrences. The patient was diagnosed with a recurrent ameloblastoma of the infratemporal fossa that was subsequently resected and reconstructed using an anterolateral thigh (ALT) free tissue transfer...

This is the second case report in English literature of a primary non-cutaneous non mucosal melanoma (NCNM) originating from Infratemporal fossa (ITF). A 21 year woman who was previously treated for craniopharyngioma 14 years back with surgery and radiation, presented with left ITF swelling which after excision was histologically confirmed to be NCNM. She has been disease free till date. Therapeutic difficulties and diagnostic dilemmas in such a case are discussed. We propose the term of non cutaneous non mucosal melanoma (NCNM) for this rare entity...

The aim of this article is to report the clinical case of a right subcondylar fracture in a 4-year-old boy. The displaced and medial angulated fragmented mandibular condyle in coexistence with an enlarged lateral pterygoid process was compressing the inferior alveolar nerve (IAN) during its course in the area of the infratemporal fossa. This was expressed by exhibiting a rubbing behavior with resulting superficial ulceration at the right lower lip. Hypoesthesia of the lower lip may be a sign of the IAN entrapment after a subcondylar fracture in a child...

The parapharyngeal space (PPS) is a challenging anatomical region, rich in vascular and nervous vital structures. Surgery is considered the treatment of choice for the majority of PPS lesions. Herein, we present a retrospective evaluation on ten patients with various types of lesions of the parapharyngeal and infratemporal fossa (ITF) regions operated on via an endoscopic-assisted transoral-transpharyngeal approach (EATTA), focusing on feasibility and safety. A retrospective evaluation of patients treated by means of EATTA to PPS and/or ITF lesions was carried out...

The authors present a patient of a neonate with a skull base extragonadal germ cell tumor requiring a modified facial translocation approach for resection. A 1-week-old female presented with right proptosis, eyelid edema, and nasal obstruction. Imaging revealed a 3-cm right-sided skull base mass involving the right maxillary, ethmoid, sphenoid sinuses, orbit, infratemporal fossa, and cavernous sinus via skull base erosion. The lesion was refractory to chemotherapy and required surgical excision. A modified facial translocation approach with preservation of anterior maxillary bone vascularization was used to remove the tumor, which was found to be teratoma with yolk-sac features...
