Abstract:

Because of its special anatomic features the roof of the anterior ethmoid is a preferred area for frontobasal fractures as well as an area of hazard during ethmoid surgery. As clinical experience proves, the most critical area for lesions to occur is in the vicinity of the anterior ethmoidal artery, especially where it leaves the dome of the ethmoid medially to reach the ethmoidal sulcus in the olfactory fossa. Complete ethmoidal specimens were investigated by means of histologic serial sections in the frontal plane. Forty anterior ethmoidal arteries were anatomically prepared. Special feature

Objective. To determine the variability of morphometric parameters of ethmoid bone structures in childhood and to identify the most significant of them to optimize surgical interventions. Materials and methods. Craniometry of 87 native samples of children's skulls aged 1-21 years without gender identity, and 85 computer tomograms (CT) scans of children of the same age were carried out. Measurements on skulls were made with caliper gage, metal ruler. The CT scan was performed on «Toshiba» 4-slice computer scanner «Asteion-S4» with a 0.5-1.0 mm increment.

Abstract:

ABSTRACT Fibrous dysplasia (FD) is a benign skeletal disorder in which abnormally overgrowing bony lesion replaces the normal bone. It can affect one bone (monostotic form) or multiple bones (polyostotic form). The craniofacial bones are involved in about 10% of subjects with monostotic FD. Among FD of the head and neck, the maxilla and mandible are the most frequent sites to be involved. However, its occurrence in the sinonasal tract is very rare. We report a case of a large monostotic FD of the ethmoid bone in a 29-year-old woman. The lesion was removed by lateral rhinotomy approach and path

Fibrous dysplasia is an uncommon bone disorder affecting various parts of the skeleton, often affecting facial and cranial bones. In this case, a 10-year-old patient was diagnosed with fibrous dysplasia of the ethmoid sinus at an early age. The patient has experienced nasal congestion, snores, and worsening nasal patency since 2019. A CT scan revealed an expansive proliferative lesion, likely from the frontal or ethmoid bone, protruding into the nasal cavity, ethmoid sinus, and right orbit. The tumor causes bone defects in the area of the nasal bone, leading to fluid retention in the periphera

Abstract:

A paranasal sinus mucocele is an epithelial-lined, mucus-containing sac that completely fills the sinus and forms an expandable cystic structure. It most commonly affects the frontal and ethmoidal sinuses, and rarely the maxillary and sphenoid sinuses. Orbital displacement or external disfigurement resulting from the expansion of the frontal or ethmoid sinuses is common; however, facial asymmetry caused by maxillary bone remodeling is rare. We describe a case of large maxillary sinus mucocele that destroyed the maxillary sinus bony wall, resulting in notable left cheek swelling and disfigureme

Histopathological analysis of the antrolith revealed it to be bone-like in formation. The antrolith was about 1 cm in diameter. Infrared spectroscopy revealed that the antrolith contained protein (45 per cent), calcium phosphate (43 per cent) and calcium carbonate (12 per cent).

Abstract:

Fibrous dysplasia (FD) is a non-malignant progressive condition, which replaces normal bone and marrow with fibrous tissue and woven bone. Sinus mucocele is a cystic, expansile, and destructive lesion that occurs as a result of obstruction of the sinus ostium secondary to inflammation, trauma, anatomical variation, previous sinus surgery, tumor or FD. Among them, FD combined with mucocele has been rarely reported. Here we report the first case of FD combined with ethmoid mucocele. The patient underwent endoscopic debulking of FD and marsupialization of mucocele. The mucocele was successfully m

Abstract:

The cartilaginous nasal capsule of mammals becomes highly modified during ontogeny by resorption and ossification that finally results in the ethmoid bone. A deeper understanding of the early ontogeny of the ethmoidal region helps to elucidate morphological patterns and homologies in the adult cranium. However, the perinatal development of the ethmoidal region is not well studied though this is a craniogenetic crucial time frame. This is especially the case in the most species-rich rodent group, the Muroidea. In order to elucidate the perinatal transformation of the nasal capsule histological

Abstract:

Sinus mucoceles are nonmalignant cystic tumors lined by non-neoplastic epithelium, typically involving the frontal and ethmoid sinuses. Although it is common for these mucoceles to cause destruction of surrounding bone tissue due to their growth, cerebrospinal fluid leaks resulting from skull base penetration by an ethmoid sinus mucocele have rarely been reported. A 24-year-old male patient presented with right proptosis and right periorbital pain, who underwent bilateral endoscopic sinus surgery 12 years ago. Endoscopic sinus surgery was performed to treat the right ethmoid sinus mucocele, an

(1) Background: For good surgical performance, sound knowledge of anatomy is required. Although the ethmoid air cells and sphenoid sinuses are subject to a high degree of variation, their possible extensions above the nasal fossa at the posterior end of the cribriform plate of the ethmoid bone (CPEB) were seemingly overlooked. (2) Methods: We retrospectively studied 162 case files from 55 male and 107 female cases, with ages varying from 42 to 80, which were scanned using Cone Beam Computed Tomography.

Abstract:

Abstract The frontal sinus, situated between the external and internal plates of the frontal bone, posterior to the brow ridges, is the most superior and complex structure within the paranasal sinuses. The frontal sinus outflow tract encompasses two parts: the frontal ostium superiorly and the frontal recess inferiorly, collectively forming the frontal sinus drainage pathway. The frontal recess represents the most anterosuperior portion of the ethmoid. Pneumatization of this area can extend from the agger nasi cell anteriorly to the ethmoidal bulla posteriorly. This recess is bounded by the or

Abstract:

Frontal sinus fractures are common traumatic injuries of the head and neck, accounting for 8% of facial fractures. When a severe frontal sinus fracture and a naso-ethmoid-orbital fracture occur together, a postoperative contour deformity is highly likely. A pericranial flap is a reliable and versatile tool for craniofacial reconstruction. The authors fabricated an anteriorly-based pericranial flap in multiple layers to camouflage the fracture site and augment the brow ridge for volumization. Open reduction and pericranial flap coverage using this method (dubbed the “Persian carpet” method) wer
