PURPOSE: Benign parotid tumors are adequately treated with partial parotidectomy, which is often performed under general anesthesia (GA). We have reported our preliminary results on the feasibility to perform parotidectomy under local anesthesia (LA). We hereby present our accumulated experience of partial parotidectomy under LA to further consolidate its feasibility, efficacy and safety in a larger series. MATERIALS AND METHODS: Case series review was carried out using our own center patients' database...

OBJECTIVE: Condylar and subcondylar fractures (CSFs) are among the most common mandible fractures. If reduction of these fractures is not carried out correctly, serious complications can result, including infection, damage to temporomandibular joint (TMJ) function, malocclusion, nonunion, malunion, and ankylosis of the TMJ. METHODS: We used a preauricular, mini-incision, open technique (PMIOT) for CSF of the mandible. 66 patients (48 males, 18 females), with a total of 72 CSFs of the mandible, were repaired with PMIOT between 2011 and 2016...

Jugular paragangliomas are slow growing highly vascular tumors arising from jugular paraganglia. The gold standard of treatment is complete surgical resection. Pre-operative embolization of these highly vascular tumors is essential to reduce intra-operative bleeding, allow safe dissection, and decrease operative time and post-operative complications. Onyx (ethylene-vinyl alcohol copolymer) has been widely used as permanent occluding material for vascular tumors of skull base because of its unique physical properties...

Background: Inadequate release of retaining ligaments during facelift surgery may lead to an unnatural appearance. However, most facelift surgeons are hesitant in transecting these ligaments to avoid possible injury to facial subbranches. Objectives: In our surgical practice for modified composite flap rhytidectomy we use the finger-assisted malar elevation (FAME) technique in order to enable safe release of the zygomatic cutaneous ligaments through the prezygomatic space under direct vision...

Free flaps based on static slings principles cannot provide esthetic and functional outcomes at a desired level in total or close to total lip loss. Therefore, dynamic methods have become a current issue in recent years and especially the idea of functional gracilis free muscle flap has been suggested. In this study, we present a case of a successful total lower lip repair with this flap.In a 78-year-old female patient who was diagnosed with squamous cell carcinoma involving the entire lower lip, bilateral modified radical neck dissection and full-thickness total resection with 1 cm surgical margin so as to include both commissures of the tumor were performed and then a free gracilis muscle flap was transferred from the same side...

BACKGROUND: Surgical approaches to the midcheek area are challenging. This area is included between the lower eyelid above, and the upper lip below. The peculiar anatomical location makes it really important for attractiveness, thus the need to obtain a correct balance between the operation's safety and minimally invasive aspect. To the authors' knowledge, this is the first showcase and technical description of a novel minimally invasive endoscopic approach for midcheek mass removal. METHODS: Making 3 incisions in concealed area an endoscopically aided facial dissection was performed to remove a solitary venus malformation of the left midcheek region...

Ectopic molars within the mandibular ramus/condyle unit, although rare, present a unique challenge to the surgeon. Multiple approaches have been described in the literature for their removal. A review of the English literature on the subject of mandibular ectopic molars and their epidemiology, etiology, indications for removal, and surgical techniques was completed. In addition, a case report is presented of an ectopic mandibular molar in the mid-ramus region which was removed via a minimally invasive, intraoral, technique combining the use of endoscopy and piezoelectric surgery...

The zygomaticus major (ZM) is important for the human smile. There are conflicting data about whether the zygomatic or buccal branches of the facial nerve are responsible for its motor innervation. The literature provides no precise distinction of the transition zone between these two branch systems. In this study, a definition to distinguish the facial nerve branches at the level of the body of the zygoma is proposed. In the light of this definition, we conducted an anatomical study to determine how the source of innervation of the ZM was distributed...

A 45-year-old man presented with left-sided facial swelling. Initial excisional biopsy was done somewhere else without prior imaging and it came out to be pleomorphic adenoma; local imaging after biopsy showed mass over the left parotid gland with ipsilateral lymphadenopathy. On examination, there was a well-circumscribed mass with signs of left facial nerve palsy. He underwent left radical parotidectomy with ipsilateral modified radical neck dissection, and per operatively, it came out to be neoplastic lesion...

BACKGROUND: While the subtemporal approach represents the surgical module milestone designed to reach the petrous apex, a novel ventral route, which is the superior eyelid endoscopic transorbital approach, has been proposed to access the skull base. Accordingly, we aimed to evaluate the feasibility of this route to the petrous apex, providing a qualitative and quantitative analysis of this relatively novel pathway. METHODS: Five human cadaveric heads were dissected at the Laboratory of Surgical NeuroAnatomy of the University of Barcelona...

OBJECTIVE: Sodium-2-mercaptoethanesulfonate (MESNA) is widely used in medicine because of its antioxidant and mucolytic effects. In recent years, it has been used in otologic surgery. Because it cleaves disulfide bonds, it is used to easily dissect the epithelial matrix in cholesteatoma and atelectasis. In this study, we hypothesized that MESNA does not have any toxic effect on the facial nerve, and the effects of MESNA on the facial nerve were examined histologically and electrophysiologically...

BACKGROUND: The surgical management of benign parotid tumors is aimed at complete extirpation of the mass with preservation of facial nerve function. There is a relative paucity of literature pertaining to complications after benign parotid surgery and related risk factors. We aim to critically review the outcomes following treatment of benign parotid pathology when surgery entailed either complete superficial parotidectomy (CSP), partial superficial parotidectomy (PSP) or extracapsular dissection (ECD)...

The facial nerve, the seventh cranial nerve, is of great clinical significance to oral health professionals. Most published literature either addresses the central connections of the nerve or its peripheral distribution but few integrate both of these components and also highlight the main disorders affecting the nerve that have clinical implications in dentistry. The aim of the current study is to provide a comprehensive description of the facial nerve. Multiple aspects of the facial nerve are discussed and integrated, including its neuroanatomy, functional anatomy, gross anatomy, clinical problems that may involve the nerve, and the use of detailed anatomical knowledge in the diagnosis of the site of facial nerve lesion in clinical neurology...

To investigate the topographical relationship between the frontal branch of the superficial temporal artery (FSTA) and the temporal branch of the facial nerve (TFN) with the aim of preventing nerve injury during FSTA biopsy. Fifty-seven hemifaces of 33 cadavers were dissected. Vertical lines drawn to the lateral orbital margin (LOM) and the superior root of the helix were used as the anterior and posterior reference positions, respectively. Horizontal lines drawn through the supraorbital margin and lateral canthus were used as the superior and inferior reference points, respectively...

Nerve function assessments are crucial for surgical intervention during acoustic neuroma surgery. Cranial nerves such as acoustic and facial nerves, can be possibly damaged during tumor dissection. Proper surgical intervention should prevent neurological deficit and achieve total tumor removal. Conventionally, nerve function is qualitatively evaluated by surgeon and neurologist. Facial nerves can be preserved by monitoring the compound muscle action potential (CMAP) response. The differences in the amplitude and latency of CMAP are used as indicators during surgical interventions...

The orbicularis oculi muscle, an important mimetic muscle, was investigated to ascertain its anatomical relation to facial aging-especially its orbital part (Oo). Previous studies of the distinct muscle bundles frequently found inferior to the Oo have provided various definitions, including that of the malaris muscle. This study aimed to examine these muscle bundles and clarify their function in facial aging. Twelve heads of Japanese cadavers (average age: 82.5 years old) were dissected to observe the muscles, focusing in particular on those in the periorbital region...

The technical advances in sonography of the past decade have supported the rapid improvement of high-resolution imaging, which enables the quick visualization of peripheral nerves at relatively limited costs. Recently, the possibility of visualizing the extratemporal facial nerve (FN) has been considered. This manuscript describes the first systematic evaluation in cadavers, of a novel ultrasonographic approach with this specific aim. Eight cadaveric hemifaces were evaluated by means of high-frequency ultrasound with two linear (13 and 22 MHz) and a convex transducer (6...
