Bilateral choanal atresia and paranasal sinus hypoplasia in an adult patient with hypogammaglobulinaemia

Bilateral Choanal Atresia in 24 Years Old Woman: A Case Report

Background

Choanal atresia is a congenital anomaly characterized by an absence of the nasal choanae due to Failure to recanalize the nasal fossae during embryogenesis. Instances involving unilateral Choanal atresia may go unidentified for extended periods. Bilateral choanal atresia presenting in adulthood is an infrequent occurrence.

Case Presentation

A case of bilateral choanal atresia in a female 24-year-old presenting to our otolaryngology department's out clinics with long-standing nasal obstruction, mouth breathing, and anosmia. She underwent endoscopic choanoplasty to reestablish patency of the posterior choana. Follow-up after one month revealed patent posterior choana.

Conclusion

Bilateral choanal atresia requires early surgical intervention in infants for survival. Adult presentations are rare. Nasal endoscopy and CT help determine the surgical approach. Endoscopic trans-nasal Chonaolplasty is typically the standard treatment.

Empirical overview of a delayed diagnosis of bilateral congenital choanal atresia in an adolescent male: management with 'coblation-assisted surgery'

Bilateral choanal atresia (CA) is a congenital anomaly consisting of an imperforated choana that leads to newborn fatalities but, if unilateral, may go unnoticed for many years. Bilateral CA occurring without significant symptoms and remaining undiagnosed for many years is rare. This case report identifies an adolescent male with bilateral CA who remained undiagnosed till adolescence. The patient presented with isolated complaints of chronic nasal obstruction and discharge and was diagnosed with bilateral CA by endoscopic and radiological evaluation. The patient underwent a coblation-assisted endoscopic CA repair, with a crossover mucoperiosteal flap technique, without stenting and with a successful outcome.

Bilateral Choanal Atresia in an Adolescent Female: A Rare Case Report

Choanal atresia is a rare congenital anomaly of the nasal cavities characterized by lack of patency of the posterior ends of one or both nasal cavities (choanae). It is the most common congenital anomaly of the nasal cavity. Bilateral choanal atresia accounts for a third of the cases and is almost invariably detected in the neonatal age due to respiratory distress. Detection of bilateral choanal atresia in adulthood is extremely rare and has been reported only a few times. We report a case of a teenage girl who was diagnosed with bilateral choanal atresia after presenting with longstanding snoring and intermittent nasal discharge. She was managed with bilateral transnasal endoscopic choanoplasty to restore the choanal patency.

Bilateral choanal atresia in a 60-year-old man: A case report and review of the literature

Choanal atresia is a congenital condition referring to the blockage of the posterior nasal cavity. As bilateral choanal atresia (BCA) causes complete nasal congestion, it usually results in death due to asphyxia in the newborn if no emergency intervention is performed. Therefore, it is very rare to see a patient with BCA who has reached an advanced age. There are only 11 adult cases reported in the recent literature. Here, we report a case of a 60-year-old man diagnosed with BCA and we discuss the clinical presentation and treatment modalities with a review of the literature.

Congenital bilateral adult choanal atresia undiagnosed until the second decade: How we did it

Background:

Bilateral congenital choanal atresia that presents in adulthood is rare. There are only eight reported cases in the literature.

Method:

We present a ninth case of adult bilateral choanal atresia diagnosed at the age of 20 years. Can a bilateral choanal atresia present so late in life when such a condition is considered incompatible with life?

Results and conclusion:

Clinical details, diagnosis, and surgical steps with a clear depiction of photographs and comparison with all other previously reported cases, which can help novel otolaryngologists in their clinical practice are discussed.

Bilateral choanal atresia in an adult - management with mitomycin C and without stents: a case report

BACKGROUND

A 23-year-old female patient presented to the outpatient clinic with bilateral nasal obstruction and discharge since birth. Endoscopic examination and paranasal sinus tomography revealed bilateral choanal atresia. She did not have any other congenital abnormalities. Her parents reported cyanosis in childhood that worsened during feeding and improved during crying; however, they had not visited a physician. She did not have remarkable complaints during early childhood or adolescence.

METHODS

The patient was operated under general anesthesia, using a 0 degrees 4 mm rigid endoscope. The orifice was widened with a curette and, to prevent stenosis, mitomycin-C (1 mg/ml) was applied topically to the nasopharyngeal orifice for 5 minutes. No stents were placed.

RESULTS

Follow-up evaluation at postoperative 12th month showed that her symptoms improved significantly and, on endoscopic examination, both choanae remained patent.
