BACKGROUND While standardized methods are established to examine the pathway from motorcortex to the peripheral nerve in patients with facial palsy, a reliable method to evaluate the facial muscles in patients with long-term palsy for therapy planning is lacking. METHODS A 3D ultrasonographic (US) acquisition system driven by a motorized linear mover combined with conventional US probe was us...

Facial nerve palsy with a parotid mass is usually associated with malignant neoplasm of parotid gland. Its occurrence as a complication of parotid abscess is extremely rare. A literature review revealed only 16 cases of facial nerve palsy associated with suppurative parotitis or parotid abscess were reported. We present a case of deep parotid abscess which is complicated by facial nerve dysfunc...

BACKGROUND The use of facial cross-grafting in acquired recent unilateral facial palsy provides spontaneity and emotional activation. Masseteric nerve for facial animation has mainly been described for reinnervation of neuromuscular transplants, babysitter procedures, or direct facial nerve cooptation. The simultaneous use in a single procedure of cross-facial nerve grafting and masseteric coop...

OBJECTIVE There are no convenient techniques to evaluate the degree of facial nerve injury during a course of acupuncture treatment for Bell's palsy. Our previous studies found that observing the electrical response of specific facial muscles provided reasonable correlation with the prognosis of electroacupuncture treatment. Hence, we used the new method to evaluate the degree of facial nerve i...

Iatrogenic facial nerve injury is one of the most severe complications of cochlear implantation (CI) surgery. Intraoperative facial nerve monitoring (IFNM) is used as an adjunctive modality in a variety of neurotologic surgeries. The purpose of this retrospective study was to assess whether the use of IFNM is associated with postoperative facial nerve injury during CI surgery. The medical chart...

Bilateral facial nerve palsy is an uncommon occurrence. We describe a case of bilateral facial nerve palsy secondary to a single cycle of high-dose paclitaxel therapy (825 mg/m2), in a woman with breast cancer. Prior to her high-dose therapy, she had a residual grade 2 peripheral neuropathy following treatment with ten cycles of standard-dose paclitaxel (total dose 3200 mg). The features of the...

A 25-years-old woman with mandibular prognathism underwent a mandibular setback by way of mandibular sagittal split ramus osteotomy (MSSRO). After 2 days of operation, she developed difficulty of closing her right eye. The blink reflex test and motor nerve conduction study of the right orbicularis oris muscle were revealed right facial neuropathy of unknown origin and House-Brackmann facial ner...

MRI appearances of the facial nerve in an HIV infected patient with acute facial nerve palsy A 27 year old white HIV positive homosexual man presented with a 6 day history of right mandibular and posterior auricular pain progressing to right facial weakness on day 7. Examination showed a right lower motor neu-ron facial palsy. On MRI performed on day 7, coronal (fig A) and axial (fig B) T1 weig...

BACKGROUND Although many patients with facial paralysis have obtained benefits or completely recovered after acupuncture or electroacupuncture therapy, it is still difficult to list intuitive evidence besides evaluation using neurological function scales and a few electrophysiologic data. Hence, the aim of this study is to use more intuitive and reliable detection techniques such as facial nerv...

OBJECTIVES/HYPOTHESIS Bell's palsy is highly associated with diabetes mellitus (DM). Either the reactivation of herpes simplex virus type 1 (HSV-1) or diabetic mononeuropathy has been proposed to cause the facial paralysis observed in DM patients. However, distinguishing whether the facial palsy is caused by herpetic neuritis or diabetic mononeuropathy is difficult. We previously reported that ...
