INTRODUCTION AND OBJECTIVES: Chemoradiotherapy is the treatment of choice for nasopharyngeal carcinoma. Local recurrences are one of the leading causes of death in these patients, and surgical salvage the treatment of choice. Our goal was to evaluate and compare the results of salvage surgery in the treatment of local recurrence of nasopharyngeal carcinomas comparing endoscopic to open approaches. METHODS: Twenty patients with local recurrence of nasopharyngeal carcinomas underwent surgery: 12 patients underwent open surgery and 8 endoscopic endonasal transpterygoid nasopharyngectomy...

OBJECTIVE: With the use of multiple endoscopic endonasal surgical corridors, extended endoscopic endonasal approaches (EEEAs) are now being used to treat a wide range of ventral skull base lesions. Our aim was to present our experience with EEEAs to the ventral skull base lesions. PATIENTS AND METHODS: The study group consisted of 106 patients (57 men and 49 women) who underwent surgery for skull base lesions using EEEAs from 2010 to 2017. The EEEA was most commonly used for giant pituitary macroadenomas, sinonasal malignancies, cerebrospinal fluid (CSF) leaks, meningiomas, craniopharyngiomas, and fibro-osseous lesions...

The endoscopic transterygoid approach to the petrous apex is a feasible/alternative approach in carefully selected patients with specific favorable anatomy, even children. This approach, unlike traditional approaches, spares cochlear and vestibular function. We report a case of a six-year-old boy with embryonal rhabdomyosarcoma of the petrous apex that was diagnosed via the endoscopic transpterygoid approach.

OBJECT: Middle fossa floor access can be challenging. Open skull base approaches have associated morbidity and yield suboptimal working angles around temporal lobe. Endoscopic endonasal approaches to the middle fossa are poorly described, but provide an improved angle. The author hypothesized that the length of the maxillary nerve can be transposed out of foramen rotundum in order to provide a path to expose the full width of the middle fossa floor through the anterolateral and anteromedial triangle...

OBJECTIVE Multiple approaches have been designed to reach the medial middle fossa (for lesions in Meckel's cave, in particular), but an anterior approach through the greater wing of the sphenoid (transalisphenoid) has not been explored. In this study, the authors sought to assess the feasibility of and define the anatomical landmarks for an endoscopic anterior transmaxillary transalisphenoid (EATT) approach to Meckel's cave and the middle cranial fossa. METHODS Endoscopic dissection was performed on 5 cadaver heads injected intravascularly with colored silicone bilaterally to develop the approach and define surgical landmarks...

The endoscopic endonasal approach (EEA) to the ventral skull base has greatly increased in popularity over the last two decades. So-called expanded EEA have opened corridors to pathology off-midline, including lesions within the cavernous sinus and Meckel's cave. A standard EEA exposure into the sphenoid sinus allows visualization of the medial cavernous sinus; a transpterygoid approach allows for surgical manipulation of the lateral cavernous sinus and Meckel's cave contents. Pituitary adenomas, meningiomas, and schwannomas are the most common pathologies in this region...

The endoscopic endonasal transpterygoid approach is a versatile technique, providing direct access to the petrous apex through an anterior surgical corridor. In this review we detail the transpterygoid approach to the petrous apex and highlight its relative indications. Although this approach is a useful strategy for many lesions of the petrous apex, disease extension into lateral, superior, or posterior compartments may limit extent of resection afforded by an anterior approach alone. Based on these considerations, a disease compartment-specific strategy is discussed...

OBJECTIVE The endoscopic endonasal approach (EEA) has been shown to be an effective means of accessing lesions of the petrous apex. Lesions that are lateral to the paraclival segment of the internal carotid artery (ICA) require lateralization of the paraclival segment of the ICA or a transpterygoid infrapetrous approach. In this study the authors studied the feasibility of adding a contralateral transmaxillary (CTM) corridor to provide greater access to the petrous apex with decreased need for manipulation of the ICA...

The authors describe the surgical anatomy for the endoscopic endonasal approach (EEA) to the ventrolateral skull base. The ventrolateral skull base can be divided into two segments: the upper lateral and lower lateral skull base. The upper lateral skull base includes the cavernous sinus and the orbit, while the lower lateral skull base includes the petrous apex, Meckel's cave, parapharyngeal space, infratemporal fossa, etc. To gain access to the upper lateral skull base, a simple opening of the ethmoid sinus provides sufficient exposure of this area...

OBJECTIVE The endoscopic endonasal transmaxillary transpterygoid (TMTP) approach has been the gateway for lateral skull base exposure. Removal of the cartilaginous eustachian tube (ET) and lateral mobilization of the internal carotid artery (ICA) are technically demanding adjunctive steps that are used to access the petroclival region. The gained expansion of the deep working corridor provided by these maneuvers has yet to be quantified. METHODS The TMTP approach with cartilaginous ET removal and ICA mobilization was performed in 5 adult cadaveric heads (10 sides)...

We report a case of a seventeen-year old, healthy, non-obese young woman who presented with retro-orbital headaches and metallictasting, left-sided rhinorrhea. Computed tomography revealed a defect along the medial wall of the canal of V2 within a well-pneumatized lateral recess of the left sphenoid sinus. Prior imaging obtained 4 years earlier in the context of nasal trauma showed no such defect - thus lending support for the arachnoid granulation hypothesis of spontaneous CSF leaks from the sphenoid sinus...
