Speech after a maxillectomy: the nasal voice and how it improves | CION Cancer Clinics
Your voice sounds nasal after a maxillectomy because air is escaping into the nose through the opening left in the roof of the mouth. Once a plate or flap seals that opening, most of the nasal tone goes, and clear speech returns with practice over weeks to months. This page explains what changes, how it comes back, and what a speech therapist does. CION Cancer Clinics’ surgical oncologists in Hyderabad can talk this through with you.

The short answer
Why does my voice sound nasal after a maxillectomy?
Your voice sounds nasal because air that should come out of the mouth is escaping up into the nose through the opening the operation left in the roof of your mouth. Once that opening is sealed by a plate or a flap, most of the nasal sound goes. Clear speech then comes back with practice, usually over weeks to months.
What the roof of the mouth does for speech
The maxilla is the upper jaw. Its underside is the hard palate, the roof of the mouth. Almost every sound you make depends on it. Your tongue presses against it for sounds like t, d, n and l. It keeps air in the mouth so that p, b, k and s have pressure behind them. Remove part of it and air leaks upwards, consonants go soft, and the voice takes on the tone of someone speaking through their nose.
Why it changes more than once
Speech is worst in the first days, before any seal is in place. It improves sharply when the first plate goes in, drops back a little each time the plate is changed, and improves again as you adapt. If you have a flap, swelling makes it muffled at first, then it clears as the tissue settles. Expect a saw-tooth path, not a straight line.

The four ways speech changes, and what helps each
Most people have some of these, not all. Which ones depends on how much was removed and how well the seal fits.
The nasal tone
Air escaping into the nose gives every word a hollow, blocked quality. This is the change families notice most and the one a well-fitting seal improves most.
What helps
- Refitting the plate as the cavity shrinks
- Extending the plate backwards if the soft palate was affected
Soft or missing consonants
Sounds that need pressure in the mouth, such as p, b, k, s and sh, lose their edge. Listeners hear the vowels but miss the words. The therapist teaches you where to place the tongue against the new shape of the palate.
Words that run together
When teeth on one side are missing and the lip has less support, the mouth shapes words less crisply. Speaking a little slower and opening the mouth more makes a bigger difference than most people expect.
A quieter, tiring voice
Pushing air through a leak is hard work. Many people find their voice fades by evening or after a long phone call. This improves as the seal improves.
Telugu and English use the palate differently. Tell the therapist which languages you speak at home and at work.Not sure whether this applies to you?

How speech usually comes back, stage by stage
-
The first days
With a tube in the nose, swelling, and no seal yet, speech is at its worst. A notepad or a phone screen does the talking. This stage is short and it does not predict how you will sound later.
-
The first plate goes in
Speech improves immediately, often more than families expect. The plate is bulky and the tongue has to learn its shape, so words are clumsy for a while, but the nasal tone drops sharply.
-
Weeks of refitting
As the cavity shrinks the plate is relined or remade. Each change alters the shape the tongue works against, so speech dips for a day or two and then improves past where it was.
-
Therapy and practice
The speech therapist gives you exercises for tongue placement, breath control and specific sounds. Reading aloud daily, slowly, is the single most useful thing you can do at home.
-
The final plate, or a settled flap
Once the mouth has stopped changing shape, the final plate is made, or a bulky flap can be trimmed. Speech reaches its settled level over the months that follow.
On your notes
Words you may see in the speech therapy notes
- Hypernasal
- Too much sound coming through the nose. This is the nasal voice described on this page. Hyponasal is the opposite, the blocked-nose sound of a heavy cold.
- Velopharyngeal closure
- The soft palate at the back of the mouth lifting to shut off the nose during speech and swallowing. If it cannot close, air and food escape upwards.
- Intelligibility
- How much of what you say a listener understands. Therapists often score it as a rough percentage of words understood, and use it to track progress rather than to judge you.
- Articulation
- How clearly individual sounds are made by the tongue, lips and palate. Most of the exercises you are given are articulation work.
- Obturator with a speech bulb
- A plate extended backwards with a rounded part that helps the soft palate close. Used when the back of the palate was removed or does not move well.

Commonly believed
Four things families say about speech, and what is true
"He will never speak clearly again."
Most people are understood by strangers again once the seal fits well and they have done the therapy. The voice may not be exactly the same as before, particularly on the phone, but the first days after surgery are no guide at all to the end result.
"She is not talking because she is depressed."
Sometimes, and it is worth asking. But often she is not talking because talking is exhausting and embarrassing while the seal is poor. Fix the plate, give her a quiet room to practise in, and the silence usually lifts. If it does not, our counsellors can help.
"Speech therapy is for children with a stammer."
Speech and language therapists work with adults after mouth, throat and brain surgery every day. After a maxillectomy the exercises are practical and specific: where to place the tongue, how to control breath, which sounds to drill. It is skills training, not counselling.
"Taking the plate out at home will let the mouth rest."
Without the plate there is nothing to stop air going into the nose, so speech and swallowing both get worse, and the cavity can shrink unevenly. Wear it as your prosthodontist advised, and take it out to clean it rather than to rest.
Being straight with you
Who this does not help as much, and what this page cannot tell you
A good seal and therapy help most people a great deal. They help less when the soft palate at the back of the mouth was removed as well, when the tongue was also operated on, or when radiotherapy has left the mouth very dry and stiff. In those situations speech still improves, but the settled level may be lower and the therapy takes longer.
Phones, crowds and work
The hardest situations are the ones with no lip-reading and background noise: phone calls, markets, bus stands. Video calls are easier than voice calls. If your work depends on speaking, tell the therapist early. Practical adjustments, a quieter room, shorter calls, written back-up, often matter more than any exercise.
What this page cannot tell you
It cannot tell you how your own voice will sound in six months. That depends on how much palate was removed, whether the soft palate and teeth were kept, how well the seal fits, and how much you practise. Ask your surgeon to say plainly what was removed, and ask the therapist what a realistic settled level is for you.
Record a short voice note each month. Progress is slow enough to miss day to day and obvious when you compare.Questions we are asked
Common questions about speech after maxillectomy
How long until people can understand me again?
Most people are understood by family within days of the first plate going in, and by strangers over the following weeks and months as the plate is refined and therapy takes hold. It varies a great deal with how much was removed. The early days are not a guide.
Will my voice go back to exactly how it was?
Usually close, not identical. A slight nasal quality can remain, and some sounds may stay a little soft. Most people and their families stop noticing. If a particular sound or situation bothers you, the therapist can work on that specifically rather than on speech in general.
Does a flap give better speech than a plate?
Neither is better in every case. A well-fitting plate on a small gap can give very clear speech. A flap that is bulky can muffle speech until it settles or is trimmed. What matters most is that the seal is complete and the tongue has a surface it can work against.
Why is my speech worse in the evening?
Pushing air through any leak is tiring, and the muscles of the mouth and throat fatigue like any others. A dry mouth, common after radiotherapy, also gets worse through the day. Sip water, rest the voice in the afternoon, and keep important conversations for the morning.
Can I speak on the phone?
Yes, though it is the hardest situation because the listener cannot see your lips. Speak slower than feels natural, in a quiet room, and use video calls where you can. Many people find WhatsApp voice notes easier than live calls, because they can re-record.
What exercises can I do at home?
Your therapist will give you a specific set. In general: read aloud slowly every day, over-open the mouth, and practise the sounds that need pressure, such as p, b, k and s, in front of a mirror. Ten minutes several times a day does more than one long session.
Does radiotherapy make speech worse again?
It can, for a while. Soreness, thick saliva and a dry mouth during the course make the tongue less nimble and the plate less comfortable. Keep wearing the plate unless told otherwise and keep up the exercises. Speech usually recovers after the course finishes.
Is speech therapy covered by insurance or Aarogyasri?
Therapy sessions during the hospital stay are usually part of the surgical package. Outpatient sessions afterwards vary by scheme and insurer. Ask for a written note of what is included before discharge, and call the helpline if you need help checking your own cover.
