Abstract:
Objective: The aim of this study is to investigate the anatomy of the posterior and middle ethmoidal arteries from the viewpoint of an endoscopic sinus surgeon. Methods: Based on 100 computed tomography images, the anatomical position of the posterior ethmoidal artery in relation to the posterior ethmoid cells was classified into five types. The presence of the posterior and middle ethmoidal arteries, their distance from the skull base, and their length exposed in the ethmoid cells were measured. The association of patients’ age and sex, presence of the middle ethmoidal artery, and anatomical type of the posterior ethmoidal artery with the posterior ethmoidal artery distance from the ethmoid roof was analyzed. Results: The posterior ethmoidal artery’s position, relative to the ethmoid cell walls, was most often near the first wall, anterior to the optic canal (92.5%). The posterior ethmoidal artery’s distance from the skull base ranged from 0 to 6.4 mm (mean: 1.2 mm). Older age, longer length of the posterior ethmoidal artery exposed in the ethmoid cells, and absence of the middle ethmoidal artery were positively associated with a longer posterior ethmoidal artery distance from the skull base. Conclusion: Attention should be paid to the posterior and middle ethmoidal arteries.

Abstract:
Objective: To improve the results of surgical treatment of patients with cranioorbital tumors. For this purpose, for patient with high vascularized tumor of ethmoidal bone, adjacent to the medial wall of the orbit, early devascularization as the first stage and transnasal endoscopic removal of the tumor as the second stage was performed. Tumor devascularization was performed by clipping of anterior and posterior ethmoidal arteries through a transcaruncular endoscopic approach. For this, the incision of the conjunctiva, after infiltration with local anesthetics, was carried out posteriorly from the lacrimal caruncle, continuing it above and below the posterior border of the medial canthal ligament. Then, after dissection of the periosteum posterior to the posterior lacrimal crest, further stages of the surgical intervention are performed under the control of an endoscope with a viewing angle of 0°. Results. Transorbital endoscopic clipping of the ethmoid arteries allowed to significantly reduce the intensity of blood flow in the tumor tissue and perform endoscopic transnasal removal of the tumor with minimal blood loss. Intraoperative blood loss was 100 ml. No complications were recorded. Conclusion. Transorbital endoscopic clipping of the anterior and posterior ethmoidal arteries is an effective and safe method for early devascularization of partially embolized or non-embolized cranioorbital tumors. The technique is promising and requires further development.

Abstract:
AbstractWhilst it is generally accepted that the standard management for anterior or benign epistaxis is either cautery or anterior nasal packing, that of posterior or intractable epistaxis remains controversial. Various modalities of treatment, ranging from posterior nasal packing to arterial ligation and embolization, have been advocated but none have been unanimously accepted as the treatment of choice.The purpose of this paper was to determine the efficacy of internal maxillary arterial ligation versus combined internal maxillary arterial ligation and anterior ethmoid arterial coagulation in intractable epistaxis.Over a six year period, from 1985 to 1990,454 patients were admitted and treated for epistaxis. Forty-seven patients were diagnosed as having intractable epistaxis on the basis that the epistaxis failed to settle on anterior nasal packing. They were moved to the next step in management, which was combined anterior and posterior nasal packing. There were 30 failures, one was found to have choriocarcinoma of the maxilla, and was treated wtih cytotoxics, and the other 29 were moved to the next step, which was arterial ligation. Fifteen patients had internal maxillary arterial ligation, and 14 combined internal maxillary arterial ligation and anterior ethmoidal arterial coagulation.Large windows were created in both the anterior and posterior walls of the maxillary sinuses and all identifiable branches of the internal maxillary artery were dissected out carefully and two medium size ligating clips were placed over the main trunk, the sphenopalatine and the descending palatine branches. Single clips were placed on all other identifiable branches. Coagulation of the anterior ethmoidal artery was performed with a bipolar cautery. There were three (20 per cent) failures in the internal maxillary arterial ligation group and none in the combined internal maxillary arterial ligation and anterior ethmoidal arterial coagulation group. Furthermore, the three failures were successfully treated with anterior ethmoidal arterial coagulation. The conclusion is that combined internal maxillary and anterior ethmoidal arterial occlusion is the treatment of choice in intractable epistaxis.

Abstract:
Fronto ethmoidal mucocele is a benign but expansive pseudo cyst due to mucous secreting nature of fronto-ethmoid sinus. A rare presentation of frontoethmoidal mucocele was reported. Our subject a 61 years old female presented with frontoethmoidal mucocele of unusually large size and two in number which developed over 2 years. Two masses one above left supra-orbital region and next on forehead was noted along with diplopia and non-axial proptosis in left eye due to swelling. Similar findings were found on CT scan and diagnosis was confirmed during surgery. Endoscopic marsupialisation of fronto-ethmoid pyocele with incision & drainage of isolated pyocele in the frontal bone was performed under general anaesthesia. A puncture wound in the posterior table of frontal sinus which might have resulted in CSF rhinorrhoea was dealt at the same setting.

Abstract:
A 50-year-old man, with no previous history of epistaxis, was hospitalized at our facility for left recurrent posterior epistaxis. The patient underwent surgical treatment three times and only the operator’s experience and radiological support (cranial angiography) allowed us to control the epistaxis and stop the bleeding. The difficult bleeding management and control was attributed to an abnormal course of the left posterior ethmoidal artery. When bleeding seems to come from the roof of the nasal cavity, it is important to identify the ethmoid arteries always bearing in mind the possible existence of anomalous courses.

Abstract:
Abstract Introduction: Rhinosinusitis is one of the most common ENT disorders in the developed and developing world. The quest and identification of factors predisposing to chronic rhinosinusitis is the key for guiding appropriate management. Objectives The purpose of this study was to determine the prevalence of anatomical variations of the ethmoid sinus in patients with rhinosinusitis. This was done to assess and evaluate the significance of the anatomical variations of the ethmoid in the genesis of inflammatory sinus disease. Material and methods We reviewed 50 patients with rhinosinusitis, of which 38(76%) had anatomical variations of ethmoid and the extent of mucosal disease. Results Concha bullosa was found to be the most common anatomic variation and was seen in 25(50%) patients closely followed by variations in the uncinate process, paradoxically bend middle turbinate. The most commonly affected paranasal sinus was maxillary sinus (84%) followed by anterior ethmoidal sinus, posterior ethmoidal sinus, frontal sinus and sphenoid sinus in descending order. Conclusion Anatomical variations of the ethmoid sinuses are important etiological factors in the genesis of inflammatory sinus disease.

Abstract:
ABSTRACT Haller cell was first described by 18th century Swiss anatomist Albrecht von Haller. Haller cells make up the posterior and superior wall of the ethmoid infundibulum. They can cause obstruction of ethmoidal infundibulum after enlargement. Isolated infection of the Haller cell is usually very rare and should be suspected in patients with visual complaints or facial pain. Diagnosis can be made on radiology. Here, we report a patient with complaints of left-sided eye pain for the last 4 months which was finally diagnosed as Haller cell mucocele and successfully managed via endoscopic marsupialization.

Abstract:
Abstract Sinoliths are rarely found calculi of paranasal sinuses. The most rarely they were found in the sphenoidal sinuses. At a routine Cone Beam CT exam of a 52-year-old male patient clinically silent small sinoliths were found bilaterally in the sphenoidal sinuses and a larger posterior ethmoidal sinolith was found on the right side. To our knowledge, such multiple sinuses involvement has not been previously reported.
