Case Reports
Cemento-ossifying fibroma of the ethmoidal sinus in a child presenting with isolated pain in the nasal region.
The authors present a case of a previously healthy 8-year-old girl who presented with pain on the right side of the nose (bony part) radiating to the frontal and temporal regions. Physical examination was normal, whereas magnetic resonance imaging (MRI) of the facial region revealed a tumor limited to the right ethmoidal sinus with a small extension to the medial wall and the upper part of the nasal septum. The tumor was removed by using a 5-degree nasoscope and sent for pathologic examination, which revealed a cemento-ossifying fibroma of the ethmoidal sinus. ⋯ According to the World Health Organization classification, this tumor is a variant of cementifying fibromas, which represent a subgroup of cementomas, fibro-osseous lesions containing cementum. Cementifying fibromas are rare tumors. They are usually small, asymptomatic lesions, but although benign, they can develop into aggressive, expansible masses.

Injury of the zygomaticotemporal nerve causes paresthesia in its distributed area, and its entrapment induces protractive pain in case of manipulation of the orbital lateral wall, a Gillies or Dingman reduction procedure for a zygomatic fracture, or an endoscopic subperiosteal facelift. The aim of this study was to elucidate the surgical anatomy of the zygomaticotemporal nerve in the orbit and temporal area. Twenty hemifaces from 10 adult Korean cadavers (10 male and 10 female) were used in the study. ⋯ It ran just superficial to the deep layer of the deep temporal fascia toward the temporal area and innervated the temporal skin. The area innervated by terminal branches of the zygomaticotemporal nerve included a circle with 30-mm diameter, with the center located 10 mm superior to the top of the auriculocephalic sulcus and 30 mm lateral to the lateral canthus. Precautions should be taken when working in the area of the vulnerable zone during the Dingman procedure involving periorbital incision in case of zygomatic fracture.
