Frontal pneumatisation is not present in all primates, and among extant species, ethmoidally-derived frontal sinuses are only the genera Pan, Gorilla Homo. A simple repeatable method described here to quantify variation shape, size bilateral of sinuses. This has allowed first large study these variables, including analyses samples P. paniscus, troglodytes, G. gorilla several geographically dive...

A 59-year-old male presented with a large cholesterol granuloma arising from the frontal sinus manifesting as a large, fluctuated, soft mass in his brow, compressing left eye. Skull radiography showed dilation of the frontal sinus. Computed tomography and magnetic resonance imaging revealed a cystic mass extending into the left orbit and anterior cranial fossa. Gross inspection at the frontal c...

A 30‐year‐old man presented with progressive blurred vision and cosmetic facial problems within 2 years ago. Neurological examination demonstrated impaired visual acuity and constricted visual field associated with both forehead and right side craniofacial deformity in the general examination. The craniofacial computed tomography (CT) scan showed expansion and thickening in right mandible, ante...

Indications for endoscopic resection of fronto-ethmoidal osteomas have been progressively expanded thanks to optimization of surgical exposure and the development of dedicated instruments. Curved cutting drills are still suboptimal to treat hard osseous neoplasms of the frontal sinus. We present two patients affected by frontal osteoma treated with an endoscopic procedure using an ultrasonic bo...

Facial reconstruction is one of the most challenging problems faced by a reconstructive surgeon. We present a case of complex facial reconstruction with a composite trauma to the nose resulting in near total loss of skin and lining along with complete loss of left eyebrow with exposed frontal bone and partial loss of the left eyelid. We combined a temporoparietal fascial flap for reconstruction...

A male patient aged 37 years with a history of cranioencephalic trauma 21 years ago, reports a left frontal tumor beginning 4 months ago. Magnetic resonance imaging revealed a lesion suggesting mucocele (Figure 1). The patient underwent endoscopic bilateral frontal ethmoid sinusectomy. The option was made for external left frontal ethmoidectomy due to intense bone sclerosis in the frontal reces...

Ninety-three human skulls (80 adults and 13 children) have been examined and the extent of thin bone in the party walls between the orbit and the frontal, ethmoidal and maxillary sinuses has been assessed. Translucent bone is most often present in the lateral wall of the ethmoidal labyrinth and least often in the floor of the frontal sinus. In children such bone is present significantly less of...

The present study has been carried out in fifty-one adult human skulls for metopic sutures in the department of anatomy, Nepalgunj Medical College, Chisapani. Metopic sutures were found in six skulls (11.46%) This study showed higher incidences of incomplete metopic sutures (7.84%). One skull showed double incomplete sutures (one to right of bregma and other in the middle of the frontal bone in...

We present a case of a tumour in a 12-year-old mentally normal girl, who presented with a painless forehead swelling. Imaging studies demonstrated a large lesion within the right frontal lobe with erosion through the frontal bone. Histological diagnosis met all the criteria of glioblastoma with evidence of florid bone invasion. DNA methylation analysis, however, demonstrated features consistent...

The patient had pneumocephalus due to a bony defect at the level of his scalp tumour. As shown in fig 1, the frontal lobes are compressed and the interhemispheric space between the two tips of the frontal lobes gives rise to the “Mount Fuji” sign, named after its resemblance to the silhouette of the Japanese volcano. A CT of the vertex on a bone window (fig 2) shows the scalp defect, with exten...
