Background: The pneumatization of the frontal sinus is variable between individuals, including monozygotic twins. The volumetric anatomic variants of the frontal sinus are classified into aplasia, hypoplasia, medium-sized, and hyperplasia.

Abstract:

Absence of frontal sinus is usually associated with various syndromes such as craniosynostosis, osteodysplasia, down syndrome etc. Geographically, absence of frontal sinus is seen usually in areas with cold climate. This paper reports a case of 18-year old Indian woman suffering from bilateral absence of frontal sinuses which was non-syndromic in conjunction with unilateral mandibular hypoplasia. The paper also highlights the clinical significance of frontal sinus which was non-syndromic absence and its rarity in warm climate such as in South East Asian regions and the treatment options of uni

Abstract:

ABSTRACT Paranasal sinus anatomical anomalies with unknown etiology are common. Paranasal sinus-related diseases are associated with so high rate of morbidities, it becomes essential to identify the structure and pathophysiology of the paranasal sinuses. Computed tomography (CT) is a valuable tool in displaying its anatomy, any anatomic variations and diseases. As paranasal sinus development is a complex and long-lasting process, there are great structural variations between individuals. Maxillary and/or frontal sinus aplasia or hypoplasia are more common than the other types. Several degrees

Background and objective: The frontal bone contains a pair of air-filled hollow cavities called frontal sinuses, the size, shape and anatomic measurements and dimensions of the frontal sinuses are determined by the degree of its pneumatization.

Abstract:

Hypoplasia of maxillary sinus is a rather rare condition. Review of literature reveal that so far only 6 cases have been reported. Hypoplasia of frontal and sphenoid sinuses has been documented rather frequently. In this article the authors report two rare cases of hypoplasia involving all paranasal sinuses which has not been reported so far in literature. This is actually an incidental finding when routine CT scan of sinuses was performed. This patient was clinically asymptomatic. Awareness of this condition is important because of implications involved in performing FESS surgery in these pat

Abstract:

ABSTRACTBackground and AimsThe sinus anatomy should be well‐understood by the sinus surgeons to carry out functional endoscopic sinus surgery carefully. That's why CT scans are vital to provide essential clarity and accuracy for comprehensive presurgical planning with minimal risks. The aim of this study was to evaluate the frequency of anatomic variations of the paranasal sinus region by using multidetector computed tomography.MethodsA cross‐sectional study of one hundred and fifty‐three patients of all age groups was carried out in the radiology department of Shalamar Hospital Lahore from 20

Abstract:

AbstractThis study documents the incidences of complete and partial metopism and their possible relationship to frontal sinus volume (FSV) in a sample of modern adult black South Africans with a view to evaluating the hypothesis that metopism affects frontal sinus hypoplasia. FSV was measured from CT scans and the incidence of metopism was recorded from direct observations of dried cadaveric crania. The sex of each individual was known. Four linear cranial dimensions were used to compute a geometric mean by which to scale FSV. The incidence of partial metopism (38%) is comparable to that repor

Abstract:

Abstract Background Genetic and environmental factors especially climatic conditions are thought to influence the shape and size of the paranasal sinuses and anatomic variations may create both a diagnostic and therapeutic challenge. However, no study has been published about the climatic adaptation of the paranasal sinus region in different populations. This study aimed to compare the prevalence of anatomical variants in the paranasal sinus and nasal cavity using Cone-Beam Computed Tomography (CBCT) between Polish and Turkish Cypriot populations.

Abstract:

ABSTRACT Background: The ethmoid roof separates the ethmoid cells from the anterior cranial fossa. From the medial side, the roof of the ethmoid is connected to the lateral lamella of the ethmoid plate, which is the thinnest bone at the base of the skull and is most vulnerable to damage during endoscopic surgeries. The purpose of this study is to investigate the height of the lateral lamella in patients with hypoplasia/aplasia of the paranasal sinuses and deviation of the nasal septum using reconstructed multiplanar images by cone-beam computed tomography (CBCT).

Abstract:

Atretic cephaloceles (ACs) are congenital skull defects with herniation of rudimentary intracranial structures through the defect and associated with persistent falcine sinus or embryonic positioning of straight sinus. We describe five cases of ACs, out of which only one had embryonic straight sinus. Three cases had other intracranial malformations such as hypoplasia of corpus callosum, dysplastic tectum in one child and parieto-occipital polymicrogyria with falcotentorial dehiscence in the other, and frontal horn deformity and cortical dysplasia in the third. The prognosis of AC depends on th

This study aimed to assess the frontal sinus volume (FSV) on computed tomography (CT) scans in migraine patients. Cranial and paranasal CT images from 75 migraine patients (mean age: 39.14±13.63 y) and 23 control cases (mean age: 38.78±13.32 y) were analyzed retrospectively. Three-dimensionally reconstructed images of frontal sinuses were generated. Total FSV, anterolateral, and transverse diameters of the head were measured. The presence/absence and nature of supraorbital foramen and notches were evaluated. The total FSV was 8.02±5.97 cm3 in the migraine group and 8.38±4.83 cm3 in the control

BACKGROUND: Paranasal sinuses are air lled spaces present within the skull and facial bones. Paranasal sinuses region anatomy is highly variable. Knowledge of these variations is very important for radiologists as well as endoscopic surgeons for preoperative evaluation to avoid damage to adjacent vital structures. CT is the best modality to delineate the sinus anatomy as well as soft tissue structures. Thus, this study was undertaken to evaluate the anatomical variations of paranasal sinus region and ascertain their clinical importance. Study population MATERIAL: of 100 patients who underwent

Background: Sporadic cases of sinus aplasia have been reported in the literature, but only a few cases of total aplasia of paranasal sinuses have been recorded. In this report, we aim to present a case of aplasia of all paranasal sinuses except for the right ethmoid sinus which was hypoplastic. Case Report: The patient was a 50-year-old female referred for obtaining Cone Beam Computed Tomography (CBCT) prior to dental implant placement. The patient was asymptomatic and did not have any complaints or discomforts associated with the craniofacial structures. CBCT views showed bilateral abse
