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.

Isolated cementoossifying fibroma of the ethmoid bulla: A case report

April 30, 2006     Ismail Yilmaz, MD; Nebil Bal, MD; Levent N. Ozluoglu, MD
Cementoossifying fibroma is a rare nonodontogenic tumor of the periodontal membrane that arises from the mesodermal germ layer. This nonneoplastic, locally destructive tumor has occurred as an osseous lesion in the mandible, the maxilla, the zygoma, all the paranasal sinuses, and the orbital and petromastoid regions. It has occurred as an extraosseous lesion in the gingiva and the auricle. The diagnosis requires correlating a variety of clinical, radiologic, and histologic factors. The recurrence rate is high, particularly for lesions in the paranasal sinuses. Surgical management via a local excision as wide as possible is suggested. We describe the case of a 32-year-old woman with an isolated cementoossifying fibroma of the right ethmoid bulla, and we review the diagnosis, differential diagnosis, and management of this tumor.

Sinonasal lymphoma: A case report

Sinonasal lymphomas are uncommon malignancies. They are difficult to differentiate from carcinomas, and immunohistochemistry is needed to make the diagnosis. We describe an unusual case of a T cell lymphoma that involved only the paranasal sinuses in a middle-aged man. The patient presented with a complete loss of vision in one eye and lateral rectus muscle palsy, but no nasal symptoms.

Transseptal suture to secure middle meatal spacers

January 1, 2006     Neil G. Hockstein, MD; Christina B. Bales, MD; James N. Palmer, MD
Middle meatal spacers are used by many sinus surgeons to aid postoperative care. Aspiration of a spacer is a concern. We demonstrate a novel method of securing spacers with a transseptal suture to prevent aspiration. We fashion each spacer from a powder-free, nonlatex glove finger that is packed with a Merocel sponge. The open end of the finger is closed with 2-0 Prolene sutures. For a bilateral procedure, the needle is left attached to one of the spacers. A spacer is placed in each ethmoid cavity, the attached needle is passed through the anterior cartilaginous septum, and the suture is tied to the suture on the opposite spacer. For unilateral procedures, the suture on the single spacer is passed to the contralateral side and tied on itself. One week later, the transseptal suture is cut and the spacers are removed. We performed this procedure on 78 patients who had undergone total ethmoidectomy. None of the spacers migrated during the 1 week they were in place. One patient complained of pain during removal of a spacer. During follow-up of 2 to 10 months, we found no evidence of injury to the septum at the site of the transseptal suture. We conclude that the transseptal suture is a safe and cosmetically superior method of securing middle meatal spacers.
