A patient presented with what appeared to be a defect in the left medial wall of the maxillary sinus but that was actually two large maxillary ostia with the absence of a left uncinate process. He was successfully treated with functional endoscopic sinus surgery.

Surgical excision with wide margins is the treatment of choice for infantile fibrosarcoma of the maxillary sinus. Chemotherapy can be used for inoperable tumors.

Bilateral solitary maxillary sinus neurofibroma

Abstract

We present a case of simultaneous bilateral neurofibroma of the maxillary sinuses. To the best of our knowledge, this is the first reported case of solitary neurofibromas arising from maxillary antra bilaterally and independently.

Osseous metaplasia of the maxillary sinus with formation of a well-developed haversian system and bone marrow

Abstract

Osteogenesis in the maxillary sinus is a lesser known entity in otolaryngology, although it is put to good therapeutic use by maxillofacial surgeons. We present a case of postoperative osseous metaplasia in the maxillary sinus that led to the formation of mature bone with a well-developed haversian system and bone marrow. Such a finding has not been previously reported as a complication of endoscopic sinus surgery. This case highlights the importance of keeping in mind the possibility of osteogenesis within the maxillary sinus in patients who experience a recurrence of symptoms following sinus surgery.

Ectopic molar in the maxillary sinus precipitating a mucocele: A case report and literature review

Abstract

Ectopic teeth are rarely found in the maxillary sinus. When they are, they represent an anomaly of odontogenic development that is generally associated with odontogenic cysts, trauma, or idiopathic etiology. Although affected patients are often asymptomatic, documented morbidities include sinus disease that is often refractory to treatment. The diagnosis is usually made by plain-film radiography. Computed tomography is indicated when an ectopic tooth is associated with an antral mass and prior to surgery. Treatment of symptomatic patients and those with an antral mass is surgical, with either a Caldwell-Luc operation or an endoscopic procedure. We describe what we believe is the first reported case of a third molar in the roof of the maxillary sinus associated with a mucocele, and we review the literature.

A sinonasal inverted papilloma of mixed histology: Implications for management of all sinonasal papillomas

December 1, 2007     Jacob D. Steiger, MD and Alexander G. Chiu, MD
article

Abstract

Sinonasal papillomas are classically categorized by their histology. Inverted, cylindrical, and fungiform are the three subtypes used to describe these lesions, and their medical and surgical management is often based on the specific subtype. We describe a case of a sinonasal papilloma with all three subtypes represented within the same surgical specimen. To our knowledge, this represents the first such case in the literature and has implications for the management of all sinonasal papillomas.

Correlation of the ethmoid infundibulum to the medial orbital wall in maxillary sinus hypoplasia: “Infundibular lateralization,” a diagnostic CT finding

Abstract

In patients with chronic rhinosinusitis, the presence of maxillary sinus hypoplasia (MSH) may be obscured by extensive mucosal disease or nasal polyposis. Recognition of MSH and its effect on adjacent anatomic structures is of utmost clinical significance in endoscopic sinus surgery. Failure to recognize the impact that MSH has on the position of the ethmoid infundibulum relative to the medial orbital wall could lead to inadvertent damage to the wall during surgery. We conducted a prospective study of 75 patients with clinically and endoscopically proven chronic rhinosinusitis to evaluate the prevalence of MSH. We found that MSH was present in 12 patients (16.0%); 7 of the 75 patients (9.3%) had bilateral disease, and 5 (6.7%) had unilateral disease. We then correlated the relationship of the ethmoid infundibulum to the medial orbital wall as determined by computed tomography in patients with and without MSH. We found that in most cases of MSH, the ethmoid infundibulum was displaced lateral to the medial wall of the orbit; the correlation between MSH status and displacement was statistically significant (p < 0.05). We propose the term “infundibular lateralization” to describe this consistent radiologic finding in MSH.
