TWITCHES & HEMIFACIAL SPASM
Twitches
Twitches are involuntary muscle spasms that are NOT suppressible or able to be volitionally initiated and there is no compulsion to generate the movement.
Hemifacial Spasm
Unilateral repetitive, paroxysmal, uncontrollable spasmodic contractions of facial nerve innervated musculature: there is a unilateral spasmodic twitch of the eyelid, along with a facial grimace (twitch of the side of the face).
It most commonly secondary to neurovascular compression of the facial nerve; hence microvascular decompression is sometimes done to prevent the twitching.
It typically starts in the orbicularis oculi and then propagates via ephaptic transmission: the impulse passes between facial nerve branches.

Hemifacial spasm is a nervous system condition that causes one side of the face to twitch involuntarily.Learn how Acupuncture therapy can provide an alternative treatment choice.
Short-term versus long-term outcomes of microvascular decompression for hemifacial spasm
Short-term versus long-term outcomes of microvascular decompression for hemifacial spasm
Acta Neurochirurgica (2019) 161:2027–2033
Microvascular decompression (MVD) is a useful treatment for hemifacial spasm (HFS), but the postoperative course is extremely diverse. The purpose of this study was to compare short- and long-term outcomes, find the earliest optimal time for determining the long-term outcomes, and investigate the prognostic factors involved in the outcomes over time.

Fully endoscopic microvascular decompression for hemifacial spasm
Fully endoscopic microvascular decompression for hemifacial spasm
J Neurosurg 131:813–819, 2019
Hemifacial spasm (HFS) is characterized by involuntary tonic and/or clonic contractions of facial nerve muscles. Fully endoscopic microvascular decompression (E-MVD) for HFS has not been widely adopted. This paper aims to illustrate the safety and efficacy of the fully endoscopic technique for HFS treatment.
METHODS The authors conducted a single-center…

Delayed hearing loss after microvascular decompression for hemifacial spasm
Delayed hearing loss after microvascular decompression for hemifacial spasm
Acta Neurochirurgica (2019) 161:503–508
This study aimed to analyze cases of delayed hearing loss after microvascular decompression (MVD) for hemifacial spasm and identify the characteristic features of these patients.
Methods We retrospectively reviewed the medical records of 3462 patients who underwent MVD for hemifacial spasm between January 1998 and August 2017.
Results Among these, there…

Prognosis of Symptoms and Complications After Microvascular Decompression for Hemifacial Spasm
Prognosis of Symptoms and Complications After Microvascular Decompression for Hemifacial Spasm
World Neurosurg. (2018) 118:e557-e561
The aim of this study was to identify potential prognostic factors of hemifacial spasm (HFS) after microvascular decompression (MVD), to establish the appropriate way to tackle postprocedure symptoms and complications (PPSCs), and to find the incidence and duration of PPSCs.
METHODS: Two hundred and forty-eight patients with HFS were monitored between…
