A vocal fold examination should tell us much more than whether a lesion is present.

A small lesion may create a major vibratory disturbance, while a visually impressive lesion may have surprisingly little functional consequence.

What matters is the relationship between structure and vibration.

We will explore examination technique, image quality, glottic closure, mucosal wave, amplitude, symmetry, periodicity, phase characteristics, edge abnormalities, vertical level differences and compensatory behaviour.

We will examine structural lesions, scars, sulcus, cysts, polyps, Reinke’s oedema, neurological patterns and suspicious glottic lesions.

We will also discuss the limitations of stroboscopy and when other imaging technologies may provide additional information.

What should we take home?

The objective is not simply to become better at recognising lesions.

It is to learn to read vocal fold vibration and understand its relationship with the voice we hear.

Today we can measure almost everything about a voice.

That does not necessarily mean that we understand it.

Fundamental frequency, perturbation measures, cepstral parameters, spectra, formants and voice range profiles become useful only when they answer a clinical question.

We will explore acoustic recording standards, F0, intensity, harmonicity, cepstral analysis, spectrography, formants, resonance, voice range profiles, aerodynamic assessment, perceptual evaluation and patient-reported outcomes.

We will also discuss emerging digital and AI-assisted approaches to voice analysis.

But throughout the session we will keep returning to one question:

What does this number actually mean for this voice?

The aim is to move from collecting measurements to interpreting voices.

Papillomatosis represents one of the clearest conflicts between treating disease and preserving function.

The patient may undergo many procedures over a lifetime. Therefore, every intervention has consequences for the interventions that may follow.

We will discuss HPV biology, recurrence patterns, surgical technologies, laser and microdebrider approaches, office-based treatment, anterior commissure management, prevention of scarring and web formation, adjuvant therapies, bevacizumab, vaccination and evolving immunological strategies.

But our central question will remain:

How much can we treat while disturbing the vibratory tissue as little as possible?

The following Saturday we will take these principles into the operating room during a dedicated Live Surgery Session.

Sulcus is one of the conditions that has taught us most about phonosurgery.

Because treating what we see is often not enough.

The real problem may lie in altered tissue architecture, reduced pliability, abnormal tension distribution and the compensations that develop around them.

We will examine sulcus phenotypes, histology, differential diagnosis, stroboscopic findings and biomechanical consequences.

We will discuss voice therapy, augmentation, regenerative concepts, epithelial and subepithelial techniques and, importantly, relaxation strategies.

We will also discuss when surgery may create more harm than benefit.

The Live Surgery Session will focus on tissue behaviour, preservation and restoring favourable biomechanics rather than simply correcting an anatomical appearance.

Puberphonia is fascinating because the larynx may be completely normal.

Yet the voice does not reflect the anatomy.

This makes it an excellent model for understanding that voice is not produced by structure alone.

We will examine pubertal voice change, laryngeal growth, functional mechanisms of persistent high pitch, differential diagnosis, acoustic and endoscopic characteristics, manual diagnostic manoeuvres, therapy and resistant cases.

The key question will be:

If the structure is normal, what is maintaining the voice?

Understanding that distinction prevents unnecessary treatment and often leads to remarkably effective solutions.

Medialising a vocal fold is relatively easy to understand.

Restoring a voice is not.

Position, tension, vertical level, mass, respiratory function, neural recovery and compensatory behaviour all influence the final result.

We will review laryngeal neuroanatomy, recurrent and superior laryngeal nerve dysfunction, diagnostic work-up, natural history and the role of laryngeal EMG.

Treatment discussions will include voice therapy, injection augmentation, framework surgery, arytenoid procedures, reinnervation and combined approaches.

Most importantly, we will discuss timing.

When should we wait?

When should we use a temporary intervention?

When should we proceed to definitive surgery?

The Live Surgery Session will allow us to see how these decisions translate into the operating room.

Professional voices do not live in clinics.

They live on stages, in rehearsals, airports, hotels, buses and dressing rooms.

This session will therefore take place where these voices actually work:

BACKSTAGE.

We will explore pre-performance assessment, vocal readiness, warm-up, hydration, nutrition, allergy and reflux problems, acute symptoms, musculoskeletal factors, emergency interventions, hearing and in-ear monitoring, performance fatigue and post-performance recovery.

And we will face perhaps the most difficult backstage question:

Can this performer safely go on stage tonight?

This will not be a simulation.

Whenever possible, Backstage will be broadcast from a real summer performance environment.

Nearly two thousand years ago, Galen explored anatomy, respiration, physiology and the mechanisms of voice.

For one evening, we will leave our conventional teaching environment and return to Pergamon.

Not simply to talk about history.

But to talk about something that has always been at the heart of medicine:

How do we make a decision?

Surgical education usually teaches us what can be done.

Galen Talks will ask:

What should be done?

A concise 20-minute Galen Talk will open the evening, followed by free speeches, open discussion and challenging case debates.

We will discuss intervention versus observation, reversibility, tissue preservation, evidence versus experience, professional demands, aesthetic expectations, uncertainty, ethics and risk.

There may not always be a single correct answer.

That is precisely the point.

Galen Talks is about learning how we think.

20 min — Invited Galen Talk

30 min — Free speeches / Open floor

40–60 min — Moderated case debate

In spasmodic dysphonia, anatomy may again appear normal.

The disorder emerges during function.

We will explore laryngeal dystonia, adductor and abductor patterns, vocal tremor, task-specific examination and differentiation from muscle tension dysphonia and other neurological voice disorders.

Treatment will include botulinum toxin, target selection, dosing, EMG guidance, treatment failures and surgical alternatives.

The following week’s live session will focus on real-time assessment, target selection and procedural decision-making.

Cancer treatment must never compromise oncological safety.

But oncological safety and thoughtful voice preservation are not opposing concepts.

We will discuss leukoplakia, dysplasia, vascular patterns, advanced endoscopic imaging, biopsy versus excision, surveillance, transoral laser microsurgery, surgical depth, margins, anterior commissure involvement and early glottic carcinoma.

Particular attention will be given to understanding what tissue actually needs to be removed — and what does not.

The objective is to understand how apparently small decisions during diagnosis and surgery may determine the patient’s voice years later.

Complications belong in surgical education.

We should not hide them.

We should study them.

We will discuss bleeding, thermal injury, excessive tissue removal, scar formation, anterior webs, granulation, persistent glottic insufficiency, unintended pitch changes, airway problems and unsatisfactory functional outcomes.

But rather than simply cataloguing complications, we will ask:

Why did this happen?

Could it have been prevented?

Should we wait?

Should we rehabilitate?

Should we revise?

Knowing how to rescue a difficult outcome is as important as knowing how to perform the original operation.

Broadcast Live from a Professional Recording Studio

A microphone does not simply make a voice louder.

It changes how the voice is heard, how the performer hears themselves and sometimes how the performer produces the voice.

This session will take place inside a real professional recording studio.

Together we will explore microphone behaviour, distance, headphones, monitoring, gain, dynamic range, compression, equalisation, resonance, registers, repeated takes, fatigue and different singing styles.

We will listen to what changes when the same voice is heard:

in the room,
through the microphone,
through the headphones,
and in the final recording.

Clinicians and sound professionals often listen to the same voice from very different perspectives.

Studio is where those perspectives meet.

We begin our year looking at the vocal folds through an endoscope.

We would like to end it very differently.

Away from the clinic.

Away from the operating room.

Away from the studio.

In nature.

Because voice does not exist within the larynx alone.

Every vocal act emerges from a moving relationship between breathing, posture, muscular tone, fascia, sensory awareness, acoustic feedback and the space around us.

Even a subtle change in the body can change respiratory freedom, laryngeal behaviour, resonance and the way we perceive our own voice.

Voice in Motion is not a yoga class.

Nor is it another theoretical lecture.

It is an embodied exploration of voice.

We will explore breath and movement coordination, dynamic alignment, respiratory freedom, muscular tone, fascial continuity, movement and phonation, resonance, somatic and somatoacoustic awareness, internal versus externally perceived voice, space, listening and acoustic interaction with the environment.

Participants joining us physically in Madeira will experience the session together in nature.

Those joining online will be part of the same live experience.

The objective is not to teach a particular movement system.

It is to experience what happens to the voice when the body:

moves, releases, adapts, listens and resonates.
