Coexistence of frontal sinus hypoplasia with maxillary sinus hypoplasia: a radiological study.

The goal of this study was to determine whether frontal sinus hypoplasia coexists with maxillary sinus hypoplasia. Analyzing paranasal CT scans retrospectively, we included 86 patients who had a hypoplastic maxillary sinus at least on one side and 80 patients with bilateral normal maxillary sinuses (control group). We classified hypoplastic maxillary sinuses using the classification system previously defined by Bolger et al. (Otolaryngol Head Neck Surg 103(5):759-765, 1990). We classified the frontal sinuses as aplastic, hypoplastic, medium-sized, and hyperplastic; as previously defined by Guerram et al. (Am J Phys Anthropol 154(4):621-627, 2014). We compared the presence of frontal sinus hypoplasia using Chi-square test between the groups. The mean age of the maxillary sinus group was 43.2 (range 18-84) years. Of 86 patients, 33 (38.4%) had unilateral and 53 (61.6%) had bilateral maxillary sinus hypoplasia. Of 139 maxillary sinuses totally included, 73 (52.5%) were type 1, 51 (36.7%) were type 2 and 15 (10.8%) were type 3 hypoplastic maxillary sinuses. Of 332 frontal sinuses totally included, 25 (7.5%) were aplastic, 32 (9.6%) were hypoplastic, 172 (51.9%) were medium-sized, and 103 (31%) were hyperplastic. Of 86 patients with a hypoplastic maxillary sinus at least on one side, 29 (33.7%) had a hypoplastic and/or aplastic frontal sinus, while 10 (12.5%) had a hypoplastic and/or aplastic frontal sinus at least on one side in control group. Incidence of frontal sinus hypoplasia and/or aplasia was significantly higher in patients with maxillary sinus hypoplasia compared to the patients with bilaterally normal maxillary sinuses (χ2 = 10.384, P = 0.001). Maxillary sinus hypoplasia has a significantly higher coexistence with frontal sinus hypoplasia. This study may have an implication for anatomical studies about the development of the paranasal sinuses and paranasal sinus surgery as well as further morphological studies.

The Role of Conservative Management in Pneumosinus Dilatans Frontalis With Minimal Bony Deformity.

The authors describe the conservative management of 2 rare patients of uncomplicated pneumosinus dilatans of the frontal sinus with minimal bossing of the forehead. Regular nasal hygiene in combination with topical corticosteroids was administered with following complete resolution symptoms.

Bilateral aplasia of paranasal sinuses.

Paranasal sinus anatomical anomalies with unknown etiology are common. Maxillary and/or frontal sinus aplasia or hypoplasia are more common than the other types. Although there are some reports about paranasal sinus anomalies in the literature, there is no case similar to ours, with total paranasal sinus aplasia. Here, we present a unique case of total paranasal sinus aplasia with a symptom of fullness on the face.

Diagnosis and treatment of congenital nasal dermoid and sinus cysts in 11 infants: A consort compliant study.

There have been few studies on congenital nasal dermoid and sinus cysts (NDSCs) in infants.This study was performed to obtain clinical data for the diagnosis and treatment of NDSCs in infants.We performed a retrospective analysis of 11 infants admitted with NDSCs between 2014 and 2019. Patient demographics, lesion site, preoperative radiological findings, surgical technique, intraoperative findings, and postoperative sequelae were analyzed.In total, 11 infants (average age, 19 months; lowest age, 10 months) were included in this study. All patients presented with a nasal root mass, 2 patients also had nasal tip fistula, and only 1 case had a history of preoperative infection. Preoperative enhanced computed tomography (CT) examination showed nasal surface lesion (type I) in 3, nasal intraosseous (type II) in 5, intracranial epidural (type III) in 2, and intracranial dural (type IV) in 1 patient. The main surgical methods included direct resection with a vertical midline incision (9 patients), vertical incision + transnasal endoscopic resection + skull base repair (1 patient), and transverse incision of the lower margin of the left eyebrow (1 patient). All wounds healed well without serious complications.Using the 4-type classification method in combination with the preoperative CT findings to analyze the extent of NDSC in infants is helpful for formulating the surgical plan. Using vertical incision approach alone or combined with nasal endoscopy for minimally invasive surgery can meet the needs of complete resection and reconstruction.Our results provide clinical data that can help establish standardized criteria for the diagnosis and treatment of NDSCs in infants.

[Congenital cysts, sinuses and fistula of head and neck]. / Kystes et fistules congénitaux de la face et du cou.

Congenital cervical cysts, sinuses and fistulae are uncommon malformations. Diagnosis and management of congenital cervical cysts, sinuses and fistulae requires a good understanding of their embryological development and topography. Thyroglossal duct cysts are most common, followed by branchial cleft anomalies and dermoid cysts. In this review, we discuss both the classical and current aspects of these malformations.

A rare expression of neural crest disorders: an intrasphenoidal development of the anterior pituitary gland.

Congenital abnormalities of the pituitary gland are rare and may be associated with midline cranial, orbital, and facial anomalies and with hormonal insufficiency. Here we report a case of asymptomatic, abnormal migration of the adenohypophysis. The normally developed adenohypophysis was located in the sphenoid bone and developed on the intersphenoidal septum, extending from the superior pharyngeal wall to the floor of the sella turcica (craniopharyngeal canal). The abnormal migration of the pituitary gland was isolated without hormonal deficit, brain, or facial developmental anomalies.

Congenital maxillary sinus cholesteatoma.

Cholesteatoma of the paranasal sinuses is a rare condition. The purpose of this paper is to present a child with a congenital maxillary sinus cholesteatoma. An 18-month-old girl presented with a 4-week history of right cheek and intraoral swelling. Examination revealed a smooth swelling of the right hard palate in association with the facial swelling in the maxillary region. An inferior meatal antrostomy revealed pultaceous debris in the right maxillary antrum and biopsy confirmed a maxillary sinus cholesteatoma. The inferior meatal antrostomy was enlarged to allow exteriorisation of the disease. Recurrence of the disease has not presented on follow-up. An exteriorisation procedure as performed, in child of this age, allows normal facial growth. If recurrence develops then further treatment may be instituted in a more mature facial skeleton.

Bilateral congenital cysts in the frontal sinuses of a horse.

Congenital frontal sinus cysts were found bilaterally in the frontal sinuses of a one-year-old miniature horse. Diagnosis was based on radiography of the head and cytologic examination of tissue aspirated from the frontal sinuses. The cysts were surgically removed, using a hinged bone flap technique bilaterally over the frontal sinuses.

Congenital dental disease of horses.

Equine congenital dental deformities are not limited merely to those presented here; however, the examples discussed offer the reader an appreciation for the range of severity and complexity that may be found in affected horses. The veterinarian is obligated to provide the best possible care for the patient and to relieve animal suffering. The lack of definitive evidence for heritability of many of these defects can place the veterinarian in an untenable position, particularly when presented with literature that proclaims or suggests without evidence that a particular condition is inherited. In such cases, the veterinarian is encouraged to counsel owners, citing substantiated medical information, and to recommend that owners make the decision to eliminate the affected animals' ability to reproduce.

Congenital diseases of the equine head.

Many questions concerning heritability arise when a veterinarian is asked to supervise and treat disease of congenital origin. Genetic counseling, ethics, and legality are often confronted in discussions between animal health professionals and laymen in animal industry. Guidelines have been offered as in the 1984 statement of the Judicial Council of the American Veterinary Medical Association: "Performance of surgical procedures in all species for the purpose of concealing genetic defects in animals to be shown, raced, bred, or sold as breeding animals is unethical. However, should the health or welfare of the individual patient require correction of such genetic defects, it is recommended that the patient be rendered incapable of reproduction." The Australian Veterinary Law, Ethics, Etiquette and Convention declares it fraud to alter a defect for sale purposes and unethical for a veterinarian to perform such treatments. It is permissible to correct defects causing discomfort or inconvenience, but the veterinarian is required to advise appropriate breeding counseling. Genetic counseling has progressed significantly in human medicine. This has been supported by better diagnostic methods for genetic disorders, greater acceptance of preventive measures, and extended screening programs to identify carriers of specific abnormal genes or chromosomal aberrations. Congenital diseases in veterinary medicine are constantly under investigation. The veterinary practitioner must continue to operate with an appreciation of the incomplete understanding of most of these abnormalities and act in accordance with personal ethical judgment and the guidance of the American Veterinary Medical Association when treating the affected individual animal patient.
