Inverted Papilloma

Overview

An inverted papilloma is a non-cancerous growth that usually starts inside the nose, on the side wall of the nasal cavity, and sometimes spreads into the hollow spaces around the nose called the sinuses. The name comes from the way the cells grow: instead of bulging outward like a normal polyp, they grow inward, or 'inverted', into the tissue underneath. It is a benign (non-cancerous) tumour, but it behaves in a stubborn way — it can grow larger over time, press on nearby structures, come back after removal, and in a small number of people it can turn into a cancer over many years. Because of this, doctors treat it seriously and remove it, then keep checking the area afterwards. A different condition with a similar name can affect the bladder, but this article is about the nasal (nose and sinus) type.

It is uncommon. It makes up a small share of all growths found in the nose and sinuses — roughly 1 in 20 to 1 in 30 of them — so most people with a blocked nose do not have one.

It is seen most often in adults between about 40 and 60 years old, and men are affected more often than women — around three to five times more often. It is rare in children. People with long-standing sinus inflammation, smokers, and people exposed to wood dust at work may be at higher risk.

Symptoms

Common symptoms

• A blocked nose, usually on one side only, that does not clear with normal cold or allergy treatment
• Nosebleeds, often mild and repeated, from the same side
• A runny nose or a feeling of mucus dripping down the back of the throat
• Reduced sense of smell, or smells that seem different
• Pressure, aching or pain on one side of the face, around the cheek, eye or forehead
• A blocked feeling in one ear, or muffled hearing on the same side
• Headache or toothache-like pain in the upper jaw
• Sometimes a lump you can see or feel inside the nostril
• Snoring or noisy breathing through the nose at night
• A feeling that air is not moving through one side of the nose

Symptoms in children

• Inverted papilloma is rare in children — one-sided nasal blockage in a child is much more often caused by something simpler, such as a polyp, an infection, or something stuck in the nose
• If a child has a blocked nose on one side for more than a few weeks, repeated nosebleeds, or a change in smell, it should be checked by a doctor
• Children may describe the problem as a 'stuffy nose that never goes away' rather than using medical words

Symptoms in older adults

• Symptoms can be mistaken for ordinary sinusitis, allergies or nasal polyps, so a one-sided problem that keeps coming back deserves a closer look
• Nosebleeds may be more noticeable in people who take blood-thinning medicines — mention all your medicines to your doctor
• Reduced smell and mild facial pressure are easy to blame on 'just getting older', but a change on one side only is worth checking
• Older adults may also have other nose or sinus conditions at the same time, so a full examination matters

Causes

Main causes

• The exact cause is not fully understood. It starts when cells lining the nose grow in an unusual way.
• In some people, a common virus called human papillomavirus (HPV) is found in the growth. HPV is a very widespread virus and most people who have it never develop a papilloma — so having HPV does not mean you will get one.
• Long-term inflammation of the nose and sinuses may play a part by constantly irritating the lining.
• In most cases, no single clear cause is ever identified, and nothing you did caused it.

Risk factors

• Being an adult between about 40 and 60 years old
• Being male
• Long-standing or repeated sinus infections and sinus inflammation
• Smoking and other tobacco use
• Breathing in wood dust, or working in jobs with a lot of fine dust or fumes
• Certain types of HPV infection found in the nose
• Having nasal polyps or other long-term nasal irritation

When to see a doctor

See a doctor urgently if:

• You have a one-sided blocked nose that has lasted more than 3 to 4 weeks
• You keep getting nosebleeds from the same nostril
• You notice any change in your vision, or your eye looks pushed or swollen
• You have numbness in your cheek, lip or upper teeth on one side
• The symptoms are getting worse week by week rather than better

Book a routine appointment if:

• Your sense of smell has changed and does not seem to be recovering
• You have ongoing facial pressure or pain on one side that has not settled with usual treatment
• You have a blocked ear or muffled hearing that persists
• You snore more, or your breathing through your nose has changed
• You have been told you have a nasal polyp and it is only on one side

Diagnosis

Your doctor will ask about your symptoms and how long you have had them, then look inside your nose. In general practice, this may be a brief look with a light. If anything seems one-sided, persistent, or unusual, you will usually be referred to an ear, nose and throat (ENT) specialist. The specialist uses a thin, flexible tube with a camera and light (a nasal endoscope) to see the whole inside of the nose. This is quick, done in the clinic, and may feel a little uncomfortable but is not usually painful. To know for certain what the growth is, a small sample of tissue is taken — this is called a biopsy — and checked in a laboratory.

Tests that may be done

• A physical examination of the nose and face
• Nasal endoscopy — a small camera used to look inside the nose and see the growth clearly
• A biopsy — a small tissue sample taken and looked at under a microscope to confirm exactly what the growth is
• A CT scan of the sinuses to show how far the growth reaches and whether bone is involved
• An MRI scan, sometimes, to get a clearer picture of soft tissue and to plan surgery
• Routine blood tests before any planned procedure
• Sometimes a check for HPV on the tissue sample, as part of the laboratory assessment

What to expect at your appointment

The process is usually spread over a few appointments. You may be seen in a general practice first, then referred to a hospital ENT clinic. The camera examination is done the same day as your clinic visit. A biopsy may be taken at that visit or arranged for a short procedure. Scan results and biopsy results can take one to three weeks to come back. Waiting for results can feel stressful, and it is completely normal to feel anxious — ask your care team when to expect news and who to call if you have questions in the meantime.

Treatment

The main treatment for an inverted papilloma is surgery to remove it completely. There is no medicine that makes it shrink or disappear. Because the growth can spread into nearby sinuses and can come back after treatment, the aim is thorough removal by an ENT surgeon, followed by regular check-ups. Your team will plan treatment based on the size and position of the growth, your general health and your preferences.

Self-care at home

• Use salt-water (saline) nose rinses or sprays to keep the nose comfortable and clear — your pharmacist can advise on these
• Keep the inside of your nose moist with a humidifier or by breathing steam, especially in dry or heated rooms
• Avoid picking or blowing your nose very hard if you have nosebleeds
• Stop smoking if you smoke — this helps healing and lowers irritation in the nose
• Ask your pharmacist before using any over-the-counter cold, allergy or pain medicines, so they can check what suits you
• Write down your symptoms, when they happen and which side they are on — this helps your doctor track changes
• Tell every doctor you see about the growth, especially if you are having dental or facial treatment

Medical treatments

There is no specific medicine that cures or shrinks an inverted papilloma. Treatment is surgical. Around surgery, your team may offer general measures to keep the nose comfortable, treat infection if one is present, or manage bleeding and pain — these are chosen and prescribed by your own doctor, who will explain the pros and cons and check how they suit you. Some people are given treatment for other nasal problems, such as allergies or inflammation, so the nose is in the best possible state around the time of surgery. Always follow the advice of your own care team rather than any general information you read online.

When is surgery considered?

Surgery is the standard treatment and is usually recommended once the diagnosis is confirmed. In many cases it can be done through the nostrils using an endoscope — a thin camera-guided instrument — so there is no cut on the face. This is called endoscopic sinus surgery. Larger growths, or ones that have spread widely or into bone, may need a more extensive operation, sometimes with a small external cut. The surgery is usually done under general anaesthetic. Your surgeon will explain the planned approach, the risks, and what recovery involves. Afterwards you will need follow-up visits with a camera examination, and sometimes scans, for several years, because the growth can return — this is a normal part of the plan, not a sign that something has gone wrong.

Living with this condition

Most people recover well after surgery and notice easier breathing and fewer nosebleeds. Your nose may feel blocked, crusty or sensitive for a few weeks while it heals, and you may need salt-water rinses during that time. Follow-up appointments — usually with a camera check — are a regular part of life for a while, often every few months at first and then less often over several years. Keep a simple note of any symptoms that come back, and which side they are on, so you can share it at your appointments.

Lifestyle tips

• Avoid smoking and smoky places — smoke irritates the nose and slows healing
• Wear a mask if your job involves wood dust, fine dust or strong fumes, and follow workplace safety advice
• Keep rooms from getting too dry, and drink enough fluids
• Use a salt-water rinse if your nose feels dry or crusty, as advised by your care team
• Attend your follow-up appointments even when you feel completely well — they are how early changes are caught
• Keep a list of your medicines and bring it to appointments, especially if you take blood thinners
• Let your dentist know about your nasal surgery before any dental work

Diet and exercise

There is no special diet that treats an inverted papilloma. Eating a balanced diet and staying active help you recover from surgery and feel your best. After surgery, follow your surgeon's advice about when to return to exercise — usually light activity first, with heavier lifting and strenuous sport delayed for a few weeks to protect healing and reduce bleeding. Avoid very hot, spicy food and alcohol for a short while if your nose is healing or prone to bleeding, as these can make bleeding more likely.

Mental health and emotional wellbeing

Being told you have a growth in your nose — and hearing that it needs surgery and long-term checks — can bring worry, poor sleep and a sense of uncertainty. It is common to feel anxious while waiting for results or before an operation. These feelings usually ease as things move forward. Talk to your care team about your worries; they can explain what is happening step by step. If low mood, anxiety or worry is affecting your sleep, work or daily life, please speak to a doctor or nurse. If you ever feel overwhelmed or have thoughts of harming yourself, contact your local emergency number or a crisis support line straight away, and reach out to someone you trust — you deserve support right away.

Prevention

There is no proven way to prevent an inverted papilloma. Because the exact cause is not fully known, no single step guarantees protection. What you can do is reduce irritation to your nose: avoid smoking, protect yourself from wood and fine dust at work, treat long-standing sinus problems, and see your doctor if a one-sided nasal symptom persists. These steps support general nasal health rather than preventing this specific growth.

Vaccines

Vaccines against HPV exist and are used in many countries to prevent certain HPV-related cancers. It is not known whether HPV vaccination prevents inverted papilloma, and it is not used for that purpose. Ask your doctor or local health service whether HPV vaccination is recommended for you or your family for the reasons it is normally given.

Screening programmes

There is no general screening programme for inverted papilloma. The closest thing to screening is the follow-up your ENT team arranges after treatment — regular camera examinations, and sometimes scans — to catch any return early. That follow-up is the most important preventive step for people who have had one.

Complications

If left untreated

• The growth can keep enlarging and block the nose more and more, making breathing through that side difficult
• It can spread into the sinuses and, over time, press on or thin nearby bone
• It can press on the eye area, causing a bulging eye, double vision or other eye changes
• It can cause repeated, sometimes heavy, nosebleeds
• It can block drainage from the sinuses, leading to repeated sinus infections
• It can come back after treatment — this is quite common — which is why follow-up checks matter
• In a small number of people — roughly 1 in 10 or fewer — it can develop into a cancer (squamous cell carcinoma) over time

Long-term outlook

The outlook is generally good. An inverted papilloma is not cancer when it is found, and surgery to remove it works well for most people. The main task is staying with your follow-up plan, because the growth can return and needs to be caught early if it does. Many people find that after surgery their breathing and nosebleeds improve a lot. If you have any worries about the future, talk to your specialist — they can give you a realistic picture based on your own situation, and support is available along the way.
