Ear grommets are small ear tubes inserted into the eardrums by healthcare professionals, addressing conditions known as otitis media and 'glue ear,' where a dense, sticky fluid accumulates in the middle ear, often following repeated ear infections. The insertion of grommets is generally pain-free. These devices also referred to as tympanostomy tubes or ventilation tubes, play a crucial role in managing middle ear conditions and improving auditory function.
Grommets are small devices designed to equalise pressure in the middle ear by permitting air to enter from outside. This helps prevent the accumulation of fluid, reducing potential complications and symptoms of glue ear and effusive otitis. Constructed from either plastic or metal, grommets facilitate the entry of air into the middle ear and aid in the drainage of the thick fluid through the nasal and throat passages.
They serve as a temporary solution, aiding in ear function until the Eustachian tubes, which link the middle ear to the nasal passage, develop fully and can perform their role effectively. The tubes are inserted in the ear canal through a surgical procedure called myringotomy.
Typically, grommets remain in place for between six to eighteen months before they naturally fall out as part of the ear's normal processes. The ear grommet is usually less than 2 mm tall and smaller than a match head. It can also be called a T-tube, ear tube, pressure equalization tube, vent, PE tube or myringotomy tube.
Glue ear arises when the Eustachian tube, which links the middle ear to the back of the nose, becomes blocked. This tube is essential for maintaining air pressure and draining fluid from the middle ear, crucial for clear hearing. Blockages, often due to swelling from a cold, prevent fluid from escaping, leading to accumulation and potential infection in the middle ear.
Children under the age of 7 are particularly susceptible to glue ear, as their Eustachian tubes are smaller and less inclined. Factors increasing the risk include having hay fever, a cleft palate, Down syndrome, exposure to cigarette smoke, frequent childcare attendance with many other kids, or prolonged use of a dummy.
While less common in teenagers and grown-ups, glue ear in adults warrants thorough examination to exclude the possibility of a tumour in the nasal or throat areas as the underlying cause.
For adults experiencing ongoing effusive otitis and hearing issues that impact daily activities, considering grommet surgery might be beneficial, especially if other treatments like antibiotics or nasal sprays haven't yielded results. This procedure involves ear tube placement, which can be a permanent solution for chronic conditions.
Before the procedure, a comprehensive evaluation with an ENT specialist is essential. This will include a review of the patient medical history, an in-depth examination of the ears, nose, and throat, and a hearing test. Additional diagnostic tests, such as an MRI scan, might also be required to ascertain the necessity and suitability of the procedure.
The recovery period following ear grommet insertion for adults is relatively swift, with most individuals experiencing minimal discomfort. Generally, patients can resume activities like swimming after two weeks, avoiding jumping, diving, or underwater swimming until a follow-up appointment, typically scheduled six weeks post-surgery. Most adults can expect to return to work or their routine activities within 2 to 3 days after the operation, although taking 1 to 2 days off for complete recovery might be advisable.
For children experiencing persistent glue ear or recurrent ear infections, doctors might suggest the insertion of grommets. This recommendation usually comes into play under specific circumstances, such as:
Ear tubes can provide relief and prevent further issues, particularly in cases where conventional treatments haven't been effective. They are particularly useful for managing glue ear, a condition that can significantly affect a toddler's behaviour and overall development, including their ability to hear and learn. Glue ear in kids can lead to noticeable changes in behaviour due to the frustration and communication difficulties arising from hearing loss.

The procedure is considered for other specific conditions, such as:
It is advised against using grommets for children experiencing a single episode of otitis media with effusion (OME) if it resolves within three months.
Grommet surgery, also known as myringotomy, is a relatively quick procedure in the United Kingdom. It typically lasts about 20 minutes, although it can be as brief as 10 minutes in some cases. This surgery is generally carried out under general anaesthesia, but local anaesthesia may be used in certain situations.
The ear tubes, placed in the eardrum, help to equalise air pressure by allowing air to flow through. During the myringotomy procedure, a surgeon creates a small incision in the eardrum to insert the grommet. Typically, the tympanostomy tube remains in position for six to twelve months before naturally falling out. This process for grommet ear insertion is standard and poses no harm to your child.
Following a grommet operation, hearing typically improves swiftly. It's common to notice a bit of discharge or bleeding from the ear for a day or two post-surgery, which is considered normal. Some mild discomfort may occur after the procedure, but it can be alleviated with over-the-counter pain relievers like paracetamol, adhering to the dosage instructions provided. A subsequent hearing test will determine the improvement in hearing. Should hearing not fully recover, additional evaluations might be necessary.
To care for your child's drainage grommet, it's crucial to prevent ear infections by avoiding the entry of unclean water into the ears. ‘Dirty water’ includes bath water, heated pools, spas, rivers, lakes, dams and creeks. It's essential to keep ears dry when bathing and washing hair.
Maintaining dryness in the ears until the grommets naturally dislodge and the eardrums heal is advisable. Consult your healthcare provider for guidance on safeguarding your child's ears from water exposure while the grommets are in place. Showering, even with hair shampooing is fine. Ear tubes can also be protected using children's earplugs or as alternatives:
Yes, swimming with grommets is possible, but it's important to adhere to certain guidelines to ensure safety. Initially, a two-week healing period post-grommet insertion is crucial, during which swimming should be avoided to minimize infection risks.
After this healing phase, swimming can resume with precautions such as wearing swimming earplugs or a swim cap to keep water from entering the ears. Bathing is not restricted for individuals with tympanostomy tubes, allowing for regular practices without concern. It is also allowed to swim underwater.
For those swimming in public pools, additional measures like silicone swim caps, headbands and goggles are recommended to further protect the ears. Swimming in ocean waters and showering in clean water do not require special precautions. In natural bodies of water, you shouldn't dive too deeply to avoid increased pressure that might force water through the grommet, potentially leading to infection.
Consultation with a healthcare provider is advisable for personalised advice.
Ear grommets are designed to fall out naturally within 6 to 12 months as part of the normal healing process. The duration before they fall out can vary based on factors such as the grommet's size, shape, material, and the individual characteristics of the ear. Once a grommet falls out, the eardrum's puncture usually heals rapidly. However, some children may experience a recurrent fluid buildup and might require further treatment.
It's common and expected for grommets to fall out on their own, and this event should not cause alarm. Following the expulsion of a grommet, a follow-up hearing test is advisable to evaluate the child's auditory status. While ear discharge may occur post-insertion, it typically does not result in pain and can be managed with ear drops. Should there be any concerns or unusual symptoms post-fallout, seeking advice from a healthcare provider is recommended for proper guidance.
In rare instances, grommets may not naturally be expelled within three years in some children. Under such circumstances, a minor procedure under general anaesthesia might be necessary to remove the ear tubes. It's crucial to balance the decision for grommet removal with the risk of recurring ear infections and glue ear.
Should grommets remain beyond their intended period, several issues might arise:
It's essential to consult your healthcare provider if grommets don't expel naturally within the anticipated timeframe to manage any potential complications or concerns arising from their prolonged stay in the ear.
Blocked grommets can lead to several symptoms affecting the ears, which are important to recognise for timely management:
It's crucial to seek medical advice if these symptoms are present, as blocked ear tubes may require professional intervention or possibly the replacement of the grommets to alleviate the issue.
For both adults and children, there are several alternatives to traditional ear tube surgery. Always consult with a healthcare professional to determine the most appropriate alternative based on the specific ear condition and individual needs. Here are the procedures:
