EMG and unilateral vocal fold palsy

The authors studied the diagnostic and prognostic value of laryngeal electromyography (LEMG) in adults with unilateral vocal fold palsy. The study included 61 patients who were tested on average seven months after their palsy (4-11 months). In most cases the...

Indication and timing of electrodiagnostic tests in facial palsy

This excellent review describes the benefits and limitations of electrodiagnostic testing for patients with facial paralysis. Tests such as Schirmer, stapedial reflex and electrogustometry have been largely replaced by neurophysiologic tests like nerve excitability test (NET), electroneuronography (ENoG), surface electromyography...

Persistent dysphonia due to cricothyroid muscle dystonia – should we be requesting laryngeal EMGs for non-resolving ‘functional’ dysphonia?

This article is an interesting report of a case of persistent voice problems affecting a 43-year-old physician that significantly compromised her ability to converse and communicate at work. Specifically, she had a fluctuating voice quality that would ‘choke off’, combined...

Laryngeal Electromyography, Third Edition

The third revised and updated edition of this concise and practical handbook on laryngeal electromyography should be a useful reference guide to all laryngologists: the beginner and the established professional. The initial chapters give an overview and deal with the...

3D ultrasonography for evaluation of muscles following facial palsy

Reconstructive surgery for facial nerve palsies is not recommended beyond two to three years after a degenerative facial nerve lesion. Since the time course of muscle atrophy is variable, this timeline is a rough guideline. The only assessment method currently...

Transmastoid facial nerve decompression for persistent traumatic facial nerve paralysis

Facial nerve paralysis (FNP) can occur following trauma, with a small number of these patients requiring facial nerve decompression (FND) to aid recovery. The authors shared their experience in decompressing the facial nerve for persistent severe FNP via a transmastoid...

Botulinum toxin injection in spasmodic dysphonia

Spasmodic dysphonia is a rare neurological voice disorder, which is often missed by the inexperienced ear. There is no laboratory test or investigation to diagnose this condition therefore, it is best diagnosed by listening to the patient’s voice. Laryngeal endoscopy...

Potential benefits of turbinate sparing medial maxillectomy

Whilst endoscopic medial maxillectomy (EMM) has good results as the standard treatment option for tumours arising in the maxillary sinus, postoperative problems of crusting, epiphora and paraesthesia are not uncommon. This paper looks at modified EMM aimed at sparing the...

Hearables: in-ear sensing devices for recording of physiological signals

Colver Ken Howe Ne, Jameel Muzaffar and Manohar Bance discuss the potential of hearable systems to monitor physiological signals (e.g. from brain or heart, blood pressure, body temperature) unobtrusively. Such adaptations require high-quality sensors and sophisticated de-noising signal processing on...

UCL, UCLH and Formula One develop life-saving breathing aids for the NHS

A breathing aid that can help keep Covid-19 patients out of intensive care, adapted by mechanical engineers at UCL and clinicians at UCLH working with Mercedes-AMG High Performance Powertrains (Mercedes-AMG HPP), has been approved for use in the NHS. For...

Should we be utilising the pre-lacrimal approach for maxillary sinus inverted papilloma?

For some time now, gold standard management of the maxillary sinus inverted papilloma has been endoscopic medial maxillectomy (EMM). Recently the endoscopic prelacrimal recess approach (EPLRA) has been reported to provide good access whilst preserving the nasolacrimal duct and inferior...

Intraoperative nerve monitoring: 2017

Having written the definitive text on laryngeal nerves, Gregory Randolph and Dipti Kamani describe the benefits of intraoperative neural monitoring and, importantly, how to proceed if the nerve is pathologically involved or there is loss of signal. Over the years,...
