Agenesis of paranasal sinuses is an uncommon finding mainly seen in the frontal and maxillary sinuses. Agenesis of sphenoid sinuses is an extremely rare condition. In this article, we present an 18-year-old female patient suffering from headache and nasal obstruction without any skeletal or cranial anomalies. Axial, coronal and sagittal computed tomography revealed absent sphenoid sinuses. Surg...

Objective:  To determine the prevalence of third molar agenesis and associated characteristics.  Material Methods:  A total  of 2374 panoramic radiographs were retrieved from radiological archives evaluated in a computer monitor under optimum viewing conditions. The basic demographic data (age sex) primary findings regarding presence or absence of  molars  in maxillary mandibular arches recorde...

The thyroid gland is composed of two lobes connected by an isthmus that traverses the midline upper trachea between second and third tracheal rings. most common manifestation dysgenesis hemi agenesis or ectopic tissue. Specifically, incidence rate ranges 0.5 10%. Remember identification other anomalies during preoperative evaluation patients scheduled for surgery would significantly contribute ...

Bilateral renal agenesis/hypoplasia/dysplasia is a lethal malformation in humans with an incidence of 1.3 per 10,000 live births. In the etiology bilateral agenesis/hypoplasia/dysplasia, genetic factor plays important role. addition to factors, also involves teratogenic effect hyperglycemia on embryo mothers insulin-dependent maternal diabetes. The purpose this paper present special case which ...

BACKGROUND Dental agenesis is the most common, often heritable, developmental anomaly in humans. Although WNT10A gene mutations are known to cause rare syndromes associated with tooth agenesis, including onycho-odontodermal dysplasia (OODD), Schöpf-Schulz-Passarge syndrome (SSPS), hypohidrotic ectodermal dysplasia (HED), and more than half of the cases of isolated oligodontia recently, the geno...

Pulmonary agenesis is a rarely encountered congenital anomaly, and its average prevalence is about 1 in 100,000 births. Anomalies of the cardiovascular, musculoskeletal, gastrointestinal, or genitourinary systems may accompany in nearly half of the cases. The diagnosis of pulmonary agenesis is usually made during childhood, but the diagnosis may be delayed until adulthood in case of an absence ...

BACKGROUND The aim of this study was to investigate the prevalence of tooth agenesis, microdontia, and tooth malformation among non-syndromic oral cleft patients and their potential association with cleft type and gender. METHODS Intraoral records and radiographs of 154 patients (97 males and 57 females) were examined. The variables assessed were tooth agenesis, microdontia, dental malformati...

OBJECTIVE To examine the relationship between third-molar agenesis and different skeletal malocclusion patterns. MATERIALS AND METHODS Pretreatment records of 1046 orthodontic patients (aged 13-17 years; mean age, 14.07 ± 1.27) were used. Third-molar agenesis was calculated with respect to genders, number of missing teeth, jaws, and skeletal malocclusion patterns. The Pearson chi-square test ...
