One-year results: Transantral balloon dilation of the ethmoid infundibulum

February 1, 2010     James Stankiewicz, MD, FACS, Theodore Truitt, MD, and James Atkins Jr., MD


A prospective, multicenter research study is under way to demonstrate long-term improvement in chronic rhinosinusitis symptoms after transantral balloon dilation of the ethmoid infundibulum. Trial results from an interim analysis of symptomatic status using the Sino-Nasal Outcome Test 20 survey demonstrate significant and sustained improvement through post-procedure 1-year follow-up. Additionally, these data provide evidence that the symptomatic improvements following balloon expansion within the ostiomeatal unit to treat medically refractory inflammation of the maxillary sinuses, either alone or with concomitant anterior ethmoid disease, are similar.

Prostatic carcinoma metastatic to the paranasal sinuses: A case report

August 31, 2008     Borlingegowda Viswanatha, MS, DLO


In the paranasal sinuses, metastatic carcinoma is far less common than primary carcinoma. Metastasis of prostate cancer to the paranasal sinuses is very rare. The author describes a case of prostatic adenocarcinoma that metastasized to the frontal and ethmoid sinuses in a 68-year-old man. The patient was treated with radiotherapy but was lost to follow-up after 3 months.

Tension pneumocephalus after endoscopic sinus surgery: Case report of repair and management in absence of obvious skull base defect

February 1, 2008     Robert G. Whitmore, BA, Gabrielle Bonhomme, MD, Laura J. Balcer, MD, MSCE, and James N. Palmer, MD


Tension pneumocephalus is a rare complication of functional endoscopic sinus surgery that may lead to rapid neurologic deterioration. Patients typically display symptoms within hours after the operation, and computed tomography reveals the presence of a skull base defect. We report a unique case of subacute tension pneumocephalus with no obvious skull base defect, which was associated with a pupil-involving third-nerve palsy. We discuss management of this complication and preventive measures for avoiding pneumocephalus after functional endoscopic sinus surgery.

The use of a telescope in sinus balloon dilation

Balloon catheter dilation is being used to help improve paranasal sinus ventilation.1,2 Those who teach the technique emphasize the use of the C-arm fluoroscope and the tactile introduction of a sinus guidewire. This is followed by the insertion of the sinus balloon catheter over the sinus guidewire. The balloon is inflated, deflated, and withdrawn. All of this can usually be accomplished without the use of a sinus telescope. However, we have found that the use of a telescope in addition to fluoroscopy is quite helpful.

A 52-year-old woman presented with an 8-month history of progressive right-sided facial pain and headache. Her medical history was significant for a gunshot wound to the face approximately 10 years earlier.

An aggressive psammomatoid ossifying fibroma of the sinonasal tract: Report of a case

June 30, 2007     Bijan Khademi, MD; Nika Niknejad, MD; Jalal Mahmoudi, MD
Aggressive psammomatoid ossifying fibromas (APOFs) represent a subgroup of related fibro-osseous lesions that appears to be unique to the nasal cavity, paranasal sinuses, and orbit. These rare lesions are characterized by distinctive histomorphologic features and a tendency to affect younger patients. Histologically they are benign, but clinically they are locally aggressive. We report the case of a 15-year-old boy who had a large APOF in the left ethmoid and sphenoid sinuses. The location of this tumor made this case unusual.
