Показания к операции инфундибулотомии
Infundibulotomy has the following indications:
- Chronic sinusitis is an inflammatory process in the maxillary sinus resistant to drug treatment
- Polyps and cysts - block the nasal passages, causing a runny nose, decreased sense of smell, pain in the face, snoring
- Congenital or acquired anomalies in the structure of the infundibulum - prevent the normal outflow of secretions from the sinus
- Recurrent infections - frequent and prolonged rhinosinusitis disrupts the functioning of the sinuses
The operation is performed in the presence of foreign bodies in the maxillary sinus, which lead to chronic inflammation and accumulation of fluid in the sinus cavity. Intervention is also necessary for traumatic injuries resulting from dental procedures. They provoke inflammation of the sinuses and blockage of the nasal passages due to swelling of the mucous membrane.
Contraindications
The operation is not performed if there are absolute and relative restrictions.
Among the relative contraindications are age restrictions and pregnancy. In old age, there is a high probability of operational risks due to the presence of concomitant diseases. Doctors may postpone infundibulotomy for pregnant women until after delivery if this is possible without significant harm to the mother's health. Before starting surgical treatment, a thorough examination of the patient is necessary. The doctor issues referrals for a general blood test, coagulogram, CT or MRI. Laboratory and instrumental research methods help determine the presence of contraindications and minimize the risk of complications.
Absolute contraindications:
- Acute infectious diseases The presence of an active inflammatory process, for example, acute sinusitis, increases the likelihood of infectious complications.
- Bleeding disorders Coagulopathies or taking anticoagulants provoke bleeding.
- Systemic diseases in the acute stage Uncontrolled diabetes mellitus and severe cardiovascular disease increase the risk of complications during and after surgery.
- Oncological diseases The presence of malignant neoplasms in the nose and sinuses requires chemotherapy or radiotherapy.
- Allergic reactions to anesthesia Intolerance to the anesthetic drug makes the intervention unsafe.
- Complex anatomical features Extensive adhesions or severe deformities make the operation difficult.
- Insufficient access If the nasal passages are too narrow, the doctor selects another surgical method.
General information
How is the infundibulotomy procedure performed
Infundibulotomy involves performing a number of steps:
- Patient preparation. The doctor administers the selected type of anesthesia
- Inspection of the nasal cavity with an endoscope. The device is inserted through the nasal cavity. The camera transmits images of the inside of the nose and sinuses to a monitor, allowing the surgeon to accurately see the area being operated on
- Access. The doctor examines the nasal cavity and determines the location of the obstruction or narrowing in the infundibulum of the maxillary sinus. Using micro-instruments, he widens a narrow area or removes an obstruction (polyps, cysts, scar tissue). In some cases, a laser or micro-driller is used to remove bony obstructions
- Providing drainage. The doctor checks whether the infundibulum has become wide enough for normal removal of mucus from the maxillary sinus
- Complete operation. After all manipulations are completed, the endoscope is carefully removed. The doctor checks the surgical area for bleeding and, if necessary, stops it
In parallel, according to indications, other interventions in the nasal cavity (turbinoplasty, turbinate vasotomy, septoplasty) can be performed during infundibulotomy. The duration of the operation is 30 minutes. The patient is then transferred to a room where he recovers from anesthesia under the supervision of medical staff. Typically, discharge occurs the next day after endoscopic treatment.
