INTRODUCTION: Various aspects of the round window anatomy and anatomy of posterior tympanum have relevant implications for designing cochlear implant electrodes and visualizing the round window through facial recess. Preoperative information about possible anatomical variations of the round window and its relationships to the adjacent neurovascular structures can help reduce complications in cochlear implant surgery. OBJECTIVE: The present study was undertaken to assess the common variations in round window anatomy and the relationships to structures of the tympanum that may be relevant for cochlear implant surgery...

Facial artery perforator flaps have been recently reported by different authors for perioral, nasal alar and cheek defects, but not for intraoral reconstruction. We have extended the use of the facial artery perforator flap in a 56-year-old man with a squamous cell carcinoma of left mouth floor, who was submitted to tumor resection with marginal mandibulectomy and left supraomohyoid neck dissection. The flap was designed according to the size of the defect (5 × 3 cm), centered on the perforator to create a symmetric flap and was tunnelled intraorally by means of a 90° rotation...

INTRODUCTION: The retrograde approach (RP) to nerve identification is a method seldom used in parotid surgery. A systematic review comparing this method to the standard anterograde approach (AP) with respect to facial nerve palsy (FNP) does not currently exist. METHODS: In a meta-analysis according to the PRISMA statement, eight publications, including one randomized controlled trial, were selected. The primary aim was to compare the temporary and permanent FNP resulting from the two dissection methods...

BACKGROUND: Vertebrobasilar dolichoectasia (VBD) is a clinical entity associated with ischemic stroke, compression of cranial nerves or brainstem, and hydrocephalus. There have been relatively few studies following the progression of VBD in patients presenting with a variety of diverse clinical features. CASE PRESENTATION: Here, we report a case study of a male with progressive VBD who was followed from November 2012 to December 2016. The patient had diagnosed hypertension for several years and suffered from left peripheral facial paralysis, recurrent ischemic attacks in the brainstem and cerebellum, obstructive hydrocephalus and frequent pneumonia...

INTRODUCTION: The extrapetrous course of the facial nerve has been a matter of study and debate since XIX century. Two different classifications have been classically proposed and widely accepted by most of the authors. Nevertheless, there are reported cases which do not fit in any of those. The aim of this study is to propose a new and useful classification. MATERIAL AND METHODS: We have used 23 embalmed Caucasian adult cadavers (11 male and 12 female) belonging to the Bodies Donation and Dissecting Rooms Centre of the University Complutense of Madrid...

A 73-yr-old man presented with intractable left hemifacial spasm of 4 yr duration. Brain magnetic resonance imaging showed significant compression of left facial nerve by the left vertebral artery (VA) and anterior inferior cerebellar artery (AICA).The patient underwent a left retrosigmoid craniotomy and a microvascular decompression of the cranial nerve (CN) VII. Intraoperatively, we found that the distal AICA had a protracted subarcuate extradural course.1 This was relieved by intra/extradural dissection...

Depression of facial contour after parotidectomy is still challenging to many of surgeons. A 68-year-old man presented with a 4-month history of a painless swelling in both parotid area. The mass was multiple and fixed at the parotid region. We conducted a parotid duct preserving bilateral superficial parotidectomy by one-stage operation to remove the multiple tumors. A lazy S incision was made in both preauricular area and the peripheral branches of the facial nerve were identified using surgical landmark...

OBJECTIVE: Microvascular decompression (MVD) is considered the first choice for the surgical treatment of trigeminal neuralgia (TN). However, recurrence after MVD is still a problem and a challenge for neurosurgeons. In this study, we share our experience in the posterior fossa re-exploration of the recurrent cases. METHODS: From January 2014 to January 2015, 15 recurrent TN patients who received fossa re-exploration were retrospectively studied. Surgeries were performed by retrosigmoid suboccipital approach...

Importance: Facial vascular anomalies are surgical challenges due to their vascularity and facial nerve distortion. To assist facial vascular anomaly surgical treatment, presurgical percutaneous facial nerve stimulation and recording of compound motor action potentials can be used to map the facial nerve branches. During surgery, the nerve map and continuous intraoperative motor end plate potential monitoring can be used to reduce nerve injury. Objective: To investigate if preoperative facial nerve mapping (FNM) is associated with intraoperative facial nerve injury risk and safe surgical approach options compared with standard nerve integrity monitoring (NIM)...

INTRODUCTION: Facial-nerve palsy is the most common complication during facial surgery. However, there are few detailed reports on the distribution of the terminal branches of the facial nerve to the mimetic muscles. This also applies to the communicating branches. The aim of our study was to assess the variability of communicant and terminal branches of the facial nerve in humans. MATERIALS AND METHODS: This prospective study involved anatomical dissections and intraoperative electric stimulation of facial nerves...

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...
