2. Thrombotic Microangiopathy Revealing Bone Metastases from an Ethmoid Sinus Carcinoma (Full text)

Thrombotic Microangiopathy Revealing Bone Metastases from an Ethmoid Sinus Carcinoma Cancer-related thrombotic microangiopathy (TMA) is a rare entity whose clinical and biological characteristics have been described in various tumors. Here we describe the first case of cancer-related TMA revealing diffuse bone metastases from an ethmoid sinus carcinoma.

3. A simple, single stage technique to harvest optimal ethmoid bone grafts for caudal septal deflections. (PubMed)

A simple, single stage technique to harvest optimal ethmoid bone grafts for caudal septal deflections. Curvature of the caudal septum is a challenging area to surgically address because it is a tip supporting structure. Several methods to straighten the caudal septal deviation have been described to date. One commonly described technique is the placement of a bony septal batten graft. However, the harvest and subsequent ex vivo shaping of the bone graft can be difficult and lead to fracture (...) of the graft superstructure. Here we discuss a novel single stage endoscopic approach to harvest a preformed batten graft and apply it to correct a caudal septal curvature deformity.Description of a novel endoscopic technique for the single stage harvest of a bone graft for the correction of a caudal septal deflection utilizing an open Jansen-Middleton septum forceps.We have successfully utilized this technique in 10 patients with a caudal septal curvature deformity with no complications.

4. New TASER injuries: lacrimal canaliculus laceration and ethmoid bone fracture. (PubMed)

New TASER injuries: lacrimal canaliculus laceration and ethmoid bone fracture. The TASER is a non-lethal conducted electrical weapon intended to incapacitate a person. The growing use of the TASER has resulted in an increased risk of injuries, including those to the face. We report a case of lacrimal canaliculus laceration and ethmoid bone fracture caused by an extra penetration (XP) TASER X26 dart. A 35-year-old was subdued with a TASER head shot; the probe was discharged into the left medial (...) canthus without causing any ocular lesions. A computed tomography scan revealed the probe to be embedded in the left nasolacrimal duct and showed a displaced ethmoid fracture. The barbed dart had sectioned the inferior lacrimal canaliculus without electrifying the lesion. This case expands the knowledge of injuries that may occur as a result of the use of this device and the management of peri-ocular TASER injuries.

5. Primary osteogenic osteosarcoma of the ethmoid sinus in an adolescent: case report (Full text)

Primary osteogenic osteosarcoma of the ethmoid sinus in an adolescent: case report Osteosarcomas of the craniofacial bones account for fewer than 10% of all osteosarcomas. Primary osteosarcomas of the nasal cavity and paranasal sinus are rare (0.5-8.1% of the osteosarcomas occur in this location). Because of the rarity of this presentation, we report a case of osteogenic osteosarcoma arising de novo from the ethmoid bone in a 13 year old male who presented with discharge from the right eye

7. Decreased postoperative pain after reduction of fractured nasal bones using a nerve block of the anterior ethmoidal nerve. (PubMed)

Decreased postoperative pain after reduction of fractured nasal bones using a nerve block of the anterior ethmoidal nerve. There is consensus that all patients should experience minimal pain following reduction of a fractured nasal bone. The issue requiring further study is what technique will provide patients with the greatest pain relief following the reduction of nasal fractures. This study investigated the use of an anterior ethmoidal nerve block as preemptive analgesia for the management (...) of postoperative pain associated with reduction of nasal bone fractures. The medical documents of 85 patients were reviewed for a retrospective case-controlled comparative study. Patients in the nerve block group (n=45) were injected with 2% lidocaine containing epinephrine into the anterior ethmoidal nerve and dorsal periosteum, and those in the control group (n=40) were not. The rate of patients requiring postoperative injectable analgesics was compared between the two groups. The rate of patients who

8. Giant osteoid osteoma of the ethmoid bone with unusual large nidus (Full text)

Giant osteoid osteoma of the ethmoid bone with unusual large nidus Osteoid osteoma (OO) is a benign bone neoplasm which is seen in the long bones of appendicular skeleton. It is rarely seen in the cranium. Ethmoid bone OO has been very rarely reported so far. We report another case of giant osteoid osteoma involving the ethmoid bone with intraorbital and intracranial extension in a 3O year old female patient. This case with unusual anatomical location was presented. It is first time reporting (...) a giant osteoid osteoma of ethmoid bone with such a large nidus.

11. Endoscopic anatomy of the middle ethmoidal artery. (PubMed)

Endoscopic anatomy of the middle ethmoidal artery. The purpose of this study was to describe the incidence of the middle ethmoidal artery and its anatomical nuances via an endoscopic endonasal approach.A cadaveric study was performed on 22 adult specimens. First, a frontal sinusotomy and ethmoidectomy were performed via an endoscopic endonasal approach in order to fully expose the anterior skull base. Subsequently, the lamina papyracea and the bone of the canals covering the ethmoidal (...) neurovascular bundles were removed to identify the anterior, middle, and posterior ethmoidal arteries. Presence, laterality, and location of the middle ethmoidal artery were recorded.A total of 14 middle ethmoidal arteries were identified (10 right and 4 left), among 44 sides (22 specimens), accounting for an incidence of 31.8%. Bilateral middle ethmoidal arteries were found in 3 of 22 specimens (14%). Endonasal endoscopy features of the middle ethmoidal artery were noted.This is the first study assessing

12. Giant Ethmoid Osteoma Originated from the Lamina Papyracea (Full text)

Giant Ethmoid Osteoma Originated from the Lamina Papyracea Osteomas are slow- growing, benign tumors. They are the most common neoplasms of the paranasal sinuses. They are usually originates from the frontal and ethmoid sinus and much less frequently seen in the maxillary and sphenoid sinuses. Although the lamina papyracea is a part of ethmoid bone, a giant osteoma originated from the lamina papyracea is very uncommon. An osteoma of the paranasal sinus is usually asymptomatic. Headache

bones contribute to the walls of the ethmoid sinus. [ ] Medially, the ethmoid sinus is demarcated by the lamina papyracea, which forms the medial wall of the orbit and the lateral nasal wall. Superiorly, it is demarcated by the fovea ethmoidalis. [ , ] The infundibulum of the ethmoid represents a cleft that is demarcated by the uncinate process on its medial side and the lamina papyracea on its lateral side. [ ] It connects the inferior aspect of the hiatus semilunaris with the superomedial aspect (...) into the maxillary sinus. A curette is used to enter this area, which is enlarged with a Kerrison rongeur or other bone cutting instruments. This allows access to most of the anterior cells, but the most anterior cells may be difficult to reach. The posterior cells of the ethmoid sinus can also be reached. Balloon sinuplasty has been used in chronic sinusitis involving the frontal sphenoid and maxillary sinuses. The ethmoid sinuses are less well suited for this owing to their anatomy.

16. Paediatric aneurysmal bone cyst: not as easy as ABC (Full text)

Paediatric aneurysmal bone cyst: not as easy as ABC Aneurysmal bone cysts (ABCs) are expansile cystic lesions that can affect any bone of the body. Whilst these lesions are histologically benign, the lesions are locally aggressive and can affect the integrity of the affected bone as well as surrounding structures. ABCs arising in the head and neck region, particularly the paranasal sinuses are rare and they are limited to case reports in the literature. Due to the proximity of critical (...) anatomical structures and the visual apparatus, the potential complications can be devastating. The present article discusses both the clinical and radiological findings of an ABC arising from the ethmoid sinuses in a 6-year-old child and the potentially challenging diagnosis with its complex ensuing surgical management. The identification of an ABC arising in the paranasal sinuses is both a diagnostic and surgical challenge and ideally requires complex management in a joint paediatric ENT
