sphenoidotomien

Sphenoidotomien, also known as sphenoid sinusotomies, are surgical procedures aimed at opening or enlarging the natural drainage pathways of the sphenoid sinus, a small air-filled cavity located within the sphenoid bone at the base of the skull. These procedures are typically performed to address chronic sinusitis, polyps, or other obstructive conditions that impede proper sinus drainage, often when conservative treatments such as medication or endoscopic sinus surgery have failed.

The sphenoid sinus is situated posterior to the nasal cavity and is less accessible than other sinuses, which makes its surgical intervention more complex. Sphenoidotomien are commonly performed using endoscopic techniques, allowing surgeons to visualize and manipulate the sinus anatomy with minimal invasiveness. The procedure may involve the removal of obstructive tissue, such as polyps or inflamed mucosa, or the creation of new drainage pathways to restore proper airflow and fluid drainage.

Indications for sphenoidotomien include recurrent or refractory sphenoid sinusitis, the presence of sphenoid sinus polyps, or complications such as sinus cysts or fungal infections. Preoperative imaging, such as CT or MRI scans, is essential to assess sinus anatomy and identify potential risks, such as septations or anatomical variations that could complicate the procedure.

Complications of sphenoidotomien are rare but may include bleeding, infection, or damage to adjacent structures, such as the optic nerve or carotid artery. Postoperative care typically involves nasal saline rinses, antibiotic or steroid therapy, and close follow-up to monitor healing and prevent recurrence of symptoms. Long-term success depends on addressing underlying causes of sinus disease and maintaining proper sinus hygiene.
