Smoking, Reflux and Laryngeal Health

Voice surgery works on the thin, soft covering of the vocal folds, the layer that ripples when you speak. A glottoplasty strips that covering from the front edges and asks the two raw surfaces to heal into each other. Anything that keeps the lining inflamed makes that harder, and the two commonest culprits are smoke and stomach contents coming up from below. Unlike most of the other conditions in eligibility, both are largely in your hands.

This is information from someone who has sat in on a lot of these consultations, not a clinician; your surgeon's instructions are the ones to follow.

What smoke does to the folds

Smoke is drawn straight across the folds with every breath. It dries and irritates the surface, and years of heavy smoking can cause Reinke's oedema, a watery swelling just under the lining that makes the folds heavier and the voice lower and rougher. For someone hoping to raise their pitch, that is a fold being weighed down while they work to lighten it. The swelling often eases after stopping, though long-standing cases may not fully go back.

Smoking also brings a cough, and the cough matters more here than in most surgery. In the week after a glottoplasty, the stitches are all that holds the two edges together, and a coughing fit slams the folds against each other harder than speech does. It is also a common trigger for a granuloma, a small lump of overgrown healing tissue.

Smokers' airways are more irritable under anaesthetic, with more coughing and spasm on waking, and for surgery through the mouth the breathing tube sits between the folds being operated on.

Nicotine itself, however it arrives, narrows small blood vessels and slows healing. That matters for the lining inside and for the neck incision used in cricothyroid approximation, feminization laryngoplasty, relaxation thyroplasty and a tracheal shave.

Vapes, pouches and cannabis

Vaping removes the tar but not the nicotine, and still puts a warm aerosol across the folds. Research on vaping and the larynx is thinner than for cigarettes, and most surgeons I have seen treat it as smoking. Pouches, gum and patches spare the folds the aerosol but still deliver nicotine. Some surgeons accept replacement therapy as a step towards stopping, and others want nothing at all; ask for the exact wording, because "no smoking" and "no nicotine" are different instructions.

Cannabis smoke is hot and usually unfiltered, and there is little reason to think it is gentler on the folds than tobacco, though it has been studied far less. Joints often contain tobacco too. Tell the anaesthetist about any regular use, edibles included.

How long to stop for

The instruction I have seen most often is several weeks off before surgery and several after, covering the healing weeks; after a glottoplasty that is the stretch when the web forms. A few surgeons test for cotinine, the breakdown product of nicotine, though that is less routine for voice surgery than for operations built on flaps and grafts. Going back to smoking later puts the same irritation on a voice you have paid a lot to change.

The people I have watched find the silent week hardest were often the ones who had given up nicotine only days before. Craving is harder to manage when you cannot talk your way through it. Stopping well ahead of the minimum avoids stacking the two.

Reflux that reaches the larynx

The reflux that concerns voice surgeons is laryngopharyngeal reflux, or LPR, where small amounts of stomach acid and pepsin, a digestive enzyme, travel all the way up and land on the larynx. Many people with LPR never get heartburn at all, which is why it is sometimes called silent reflux.

What people notice instead is frequent throat clearing, a feeling of a lump or mucus in the throat, a voice that is hoarse in the morning or tires quickly, and a nagging cough. On the scope, a laryngologist looks for redness and swelling at the back of the larynx, over the small cartilages the folds attach to. Those signs are not specific to reflux, so the diagnosis is partly a judgement, and two surgeons can read the same picture differently.

Surgeons want it under control first because healing tissue bathed in acid and pepsin tends to heal more slowly and is more prone to granulomas, and because swollen folds make the baseline measurements less reliable, so the result gets measured against a starting point that was never quite true. The throat clearing that comes with reflux is also exactly the impact healing folds should not take.

Treatment usually starts with habits: finishing the last meal a few hours before lying down, raising the head of the bed, and cutting back on alcohol, late coffee and large evening meals. Many surgeons also prescribe acid-reducing medication for a period before and after laryngeal surgery. The evidence for medication in LPR specifically is more mixed than for ordinary heartburn, but around surgery it is common practice. Dose and duration are for your surgeon or doctor to set. Some will want a trial of treatment and a second look with the scope before they book.

What else the scope looks for

The pre-operative examination, usually with stroboscopy, is the surgeon's one look at the folds before they commit. Beyond reflux, they are checking for:

• Nodules, paired callus-like bumps where the folds strike hardest. They come from strain, and people who have pushed their pitch up without good technique, or who talk all day for work, are prone to them. Therapy usually settles them, and most surgeons want them gone first because they change how the folds close.
• Polyps and cysts, usually on one side. Some need removing beforehand; some surgeons deal with them in the same operation.
• Muscle tension, where the muscles around the larynx squeeze during speech, causing dysphonia with nothing structural to see. Therapy fixes it, not surgery.
• Old intubation injury. A breathing tube from any past operation, especially a long one or a stay in intensive care, can leave scarring near the back of the folds or, rarely, narrowing just below them. Mention any long facial or genital surgery to the surgeon and the anaesthetist.
• How each fold moves. Previous thyroid or neck surgery can affect the nerve to one fold, and a fold that moves poorly changes the plan considerably.

For surgery through the mouth, the surgeon also checks how wide your mouth opens, how far your neck tips back and how your front teeth sit. A small jaw or a stiff neck can make the view difficult, which is better found at the consultation than in theatre.

What you may be asked to do first

Depending on what the scope shows, a surgeon may ask you to:

• stop all nicotine by a set date, and stay off it through the healing weeks
• treat reflux and come back for a repeat scope
• do a block of voice therapy to settle nodules or tension, which overlaps with the therapy requirements many surgeons set anyway
• get allergies or post-nasal drip under control, since both keep you clearing your throat
• list every medication and supplement you take, because some affect bleeding and the surgeon will say which to pause
• get loose teeth or crowns checked before surgery through the mouth

An active cold or chest infection near the date usually means postponing, because coughing through the first week is exactly what the surgeon is trying to avoid. If you have slipped on nicotine or your reflux has flared, say so at the pre-op appointment. The plan can change around a problem the surgeon knows about.
