Unilateral endoscopic maxillary antrostomy (anesthesia and hospitalization costs not included)
Comandarea acestui serviciu anulează reducerea.*
Endoscopic maxillary antrostomy is a minimally invasive surgical procedure used to create or enlarge the natural opening of the maxillary sinus in order to ensure proper drainage and ventilation. The procedure is performed using an endoscope inserted through the nasal cavity, without any external incisions. It is conducted unilaterally (on one side only) and is indicated in cases of chronic maxillary sinusitis or other conditions that do not respond to medical treatment.
The maxillary sinus is the largest of the paranasal sinuses, located within the maxillary bone, behind the cheekbones. Its roles include:
- Reducing the weight of the skull bones
- Humidifying and warming inhaled air
- Contributing to voice resonance
Normally, the sinus drains through a narrow canal into the nasal cavity. Blockage of this drainage pathway leads to mucus buildup and sinus infection (sinusitis).
The intervention is performed under local or general anesthesia. The ENT surgeon inserts a thin nasal endoscope and microsurgical instruments through the nasal cavity. The natural opening of the sinus is created or enlarged, and inflamed tissue, purulent secretions, cysts, polyps, or foreign bodies are removed. In cases with suspected tumors, a biopsy may be performed.
Thanks to high visual precision, damage to healthy tissue is minimal. No nasal packing is required, no visible scars remain, and mucosal recovery is typically rapid and well tolerated.
Purpose of the Procedure
- Restore the natural drainage of the maxillary sinus
- Improve ventilation and reduce inflammation
- Prevent recurrence of chronic sinusitis
- Increase the effectiveness of local treatments (sprays, rinses)
- Avoid traditional open surgeries with external incisions
Indications
- Unilateral chronic maxillary sinusitis unresponsive to medication
- Localized sinonasal polyposis
- Mucoceles or cysts of the maxillary sinus
- Uncontrolled recurrent sinusitis
- Presence of foreign bodies or fungal infections
- Suspicion of tumorous formations (for biopsy or removal)
- Traumatic injuries to sinus walls, including dental-surgery-related perforations
Contraindications
- Blood clotting disorders
- Acute infections of the nasopharynx
- Fever
- Severe systemic diseases in decompensated stages
Preoperative Preparation
- Before the intervention, a comprehensive medical evaluation is required to confirm diagnosis, establish the surgical indication, and minimize postoperative risks:
- ENT consultation with nasal endoscopy
- CT scan of the paranasal sinuses
- Fasting for 6 hours (if under general anesthesia)
- Temporary discontinuation of anticoagulants, based on professional medical advice
Procedure duration: 20–30 minutes
Recovery period: 1–2 weeks, Complete mucosal healing: up to 1 month
Mild swelling or discomfort may occur in the first few days. Follow-up medical evaluation: recommended within 1–2 weeks after the procedure.
Endoscopic maxillary antrostomy is a safe, effective, and minimally invasive procedure that allows for the treatment of sinus pathologies without external trauma and with fast recovery. It represents a modern alternative to classical surgery, offering excellent results in symptom reduction and prevention of recurrence.
