Surgical anatomy of the facial nerve: from middle cranial fossa approach to endoscopic approach. A pictorial review.
Full text linkPurpose: The pathology of the facial nerve is extremely varied and extensive knowledge of the surgical anatomy in different approaches is required to manage it. During the last 15 years, the development of endoscopic ear surgery has significantly changed anatomical concepts, introducing new surgical approaches. The aim of this review is to illustrate five different surgical approaches to the facial nerve: the endoscopic approach, the middle cranial fossa approach, two translabyrinthine approaches (one simple and one endoscopic-assisted) with decompression of the whole petrous portion of the facial nerve, and a transotic approach with temporal craniotomy. Methods: Representative cases of middle and/or inner ear pathologies, surgically treated at our ENT Department, were selected to illustrate each of the five different approaches involving the facial nerve throughout its course. Results: In all cases, the pathology was removed with effective decompression of the facial nerve. The surgical anatomy in each surgical approach is described and illustrated. Conclusions: Facial nerve surgery is challenging for ENT specialists. An excellent knowledge of facial nerve anatomy is needed to eradicate pathology, avoiding nerve injuries and providing a good outcome after surgery

Chondromyxoid fibroma of the nasal cavity in a pediatric patient: Case report and literature review
No full textWe report the case of a 5-year-old boy affected by a CMF of the ethmoid sinus invading the papyracea and ethmoidal roof. This is the second case of acquired CMF involving the sinonasal spaces in a pediatric patient. Although this neoplasm is very uncommon, particularly in young patients and at this anatomical site, it is very important to correctly diagnose these tumors for adequate treatment, which generally consists of surgical resection. © 2013 Elsevier Ireland Ltd

Facial nerve hemangioma of the geniculate ganglion: An endoscopic surgical approach
No full textFacial nerve hemangiomas are rare benign tumors arising from the venous plexus surrounding the facial nerve. Surgical management of these tumors is controversial. The goal of surgery is complete tumor removal with restoration of facial nerve function and preservation of hearing, wherever possible. The approaches most used are the translabyrinthine and middle cranial fossa approaches. In this report, we describe the first facial hemangioma treated with an endoscopic transcanal approach, combined with a retroauricular transmastoid minicraniotomy for closure of the dural defect. A great auricular nerve graft was used to reconnect interrupted nerve segments. Histopathological examination confirmed the diagnosis of a hemangioma of the first genu of the facial nerve. With magnification of the structures, the transcanal endoscopic approach allowed a radical excision of the neoplasm permitting hearing function preservation, with the possibility to work with a minimally invasive approach with respect to the labyrinthine block and cochlea. Compared to a middle cranial fossa approach, the transcanal endoscopic approach avoided labyrinthine block removal and brain retraction
Transcanal Transvestibular Endoscopic Neurectomy: First Experience
No full textObjective: Ménière's disease is an idiopathic inner ear disorder characterized by recurrent vertigo, fluctuating sensorineural hearing loss, and persistent tinnitus. In 10% to 30% of cases, conservative therapy fails, and Ménière's disease is defined as intractable. In these patients, ablative techniques with unilateral vestibular deafferentation are mandatory. Several approaches for vestibular neurectomy, which preserve hearing capability, are described. In patients presenting severe dizziness associated with high-grade sensorineural hearing loss, surgical labyrinthectomy, or selected vestibular neurectomy through a translabyrinthine approach are the treatments commonly considered. This study reports the first application of transcanal transvestibular endoscopic neurectomy in two patients with frequent disabling vertigo and high-grade sensorineural hypoacusia. Methods: This was a retrospective chart review including patients with intractable Ménière's disease who underwent vestibular neurectomy, performed in our ENT department between January 2017 and January 2020, selecting patients with disabling vertigo and high-grade sensorineural hypoacusia. We describe step-by-step the surgical technique of transcanal transvestibular endoscopic neurectomy. Results: Overall, two patients underwent transcanal transvestibular endoscopic neurectomy. We performed transcanal transvestibular neurectomy in all cases. No intraoperative complications were observed. On the 2nd postoperative day, one patient presented CSF leak, leading to surgical revision. A complete resolution of vertigo attacks was observed 6months after surgery. Conclusion: Even though this study presents a limited number of cases, transcanal transvestibular neurectomy is a promising, safe, and effective procedure in selected cases

Endoscopic Ear Surgery: Redefining Middle Ear Anatomy and Physiology.
No full textMiddle ear anatomy and physiology is highly complex, yet familiarity is important to perform middle ear surgery and understand surgically relevant ventilation pathways of the ear compartments. The middle ear is divided into five subspaces: the mesotympanum, the retrotympanum posteriorly, the epitympanum superiorly, the protympanum anteriorly, and the hypotympanum inferiorly. The Eustachian tube plays a crucial role in maintaining middle ear aeration and atmospheric pressure. There are two independent aeration routes of the epitympanum. Thanks to the advent of the endoscope, this anatomic and physiologic knowledge has allowed one to understand the pathophysiology of ear diseases, improving surgical concepts
