The frontal sinus and the ethmoidal labyrinth

Surgical and Radiologic Anatomy, 1997
In the "standard" anatomic description, the frontal bone and cribriform plate of the ethmoid bone form the base of the anterior cranial fossa. We studied the development of the ethmoidal bone as well as its relations to the frontal bone in macerated disarticulated skull bones and macerated skull bases of 35 individuals between 9 and 35 years of age.

Neuroendocrine carcinoma of the ethmoid sinus

European Archives of Oto-Rhino-Laryngology, 1994
The paranasal sinuses are a rare site for neuroendocrine carcinoma (NEC). In contrast to the other regions, NEC of the sinuses has been reported to be recurrent and locally destructive. We report a case of NEC of the ethmoid sinuses. The patient was a 16-year-old Indian boy and was treated with radiation therapy to 6500 rad.

Metastatic Melanoma to the Ethmoid Sinus

Archives of Otolaryngology - Head and Neck Surgery, 1986
Malignant melanomas comprise approximately 1.5% of all malignant tumors and one fifth of these will involve the head and neck. The surgeon who operates in this region should be familiar with all aspects of this disease. The most common site of metastasis to the nose and paranasal sinuses is via the maxillary sinus.

A Giant Osteoma of the Ethmoid Sinus

Journal of Craniofacial Surgery, 2018
AbstractOsteomas are slow-growing, benign bony tumors. Most are asymptomatic. Paranasal sinus osteoma in the pediatric population is rare; hence, there are few reports of symptomatic osteomas. The authors report the case of a giant ethmoid sinus osteoma in an 11-year-old girl who presented with diplopia and proptosis.

Cementifying fibroma of the ethmoidal sinus

The Journal of Laryngology & Otology, 1984
An interesting case of cementifying fibroma of the ethmoidal sinus is presented. This benign tumour, in this unusual site, tends to behave in an aggressive manner and radical surgery is necessary. Recurrence is frequent.
