Choanal Stenosis/Atresia Surgery
Choanal atresia is a congenital failure of the nasolacrimal membrane to canalise; bilateral form constitutes a neonatal respiratory emergency in obligate nasal breathers and requires early surgical intervention.
Choanal Stenosis/Atresia Surgery is a concept in general ENT whose meaning becomes clear only when it is linked to examination findings. Choanal atresia is a congenital failure of the nasolacrimal membrane to canalise; bilateral form constitutes a neonatal respiratory emergency in obligate nasal breathers and requires early surgical intervention. Age, symptom duration, comorbidities, earlier treatment and daily limitation can all change the interpretation. the finding assessment brings nasal-sinus symptoms, this entry throat-tonsil context, the clinical point upper-airway impact and the dictionary entry sleep links into one ENT frame. In this this topic practice approach, the term explains which finding is being assessed and why it matters. The first clinical frame for this term is to separate functional impact from safety concerns: Congenital incidence 1:5,000–8,000; 70% osseous, 30% mixed. This distinction prevents rushed treatment decisions.
In the first visit for the finding, the patient's goal and safety boundary are clarified. Duration, side, daily impact, response to medication or surgery and current reports are read together. this entry review may combine ENT examination, the dictionary entry endoscopic assessment, this topic oral cavity-oropharynx inspection and this term audiological testing when useful. the finding decisions record fever, this entry pain-bleeding pattern, the clinical point hearing or nasal blockage, the dictionary entry sleep impact and this topic infection recurrence separately. Assessment of this term looks for consistency between history and examination: Bilateral: airway stabilisation (oral airway/McGovern nipple/intubation) and definitive repair. If findings do not match, staged reassessment or a second opinion may be clearer than moving directly to a procedure. Laboratory work, audiology, endoscopy, ultrasound, CT, MRI or biopsy is requested only when it improves decision quality.
A the finding plan aims to reduce symptoms without adding unnecessary procedural burden. Mild stable findings are discussed as lower-urgency observation points, while progressive or structural changes are handled with more caution. this topic planning discusses medical treatment, this term allergy control, the finding endoscopic procedures, this entry adenoid-tonsil strategy or the clinical point airway surgery by indication. The goal in the dictionary entry is not to choose the most aggressive option, but to find the right step between safe observation and effective intervention. Options are ordered by comparing short-term relief with preservation of long-term function.
Monitoring for this topic compares previous examination, imaging, tests or operation notes with the current picture. this term follow-up compares pain, the finding nasal openness, this entry sleep quality, this term hearing impact and the finding infection recurrence over time. When this entry is explained, patient goals, medical necessity and realistic expectations meet on the same ground. Follow-up advice separates warning signs without creating panic; the clinical point context with high fever, breathing difficulty, bleeding or one-sided progression deserves reassessment.
This the dictionary entry entry prepares patients and relatives but does not diagnose. Safer conclusions come from combining the complaint with examination findings, test results when needed, risk profile and a review plan.
During preparation, this topic context: expectations and possible limits stay in one note; the safety boundary stays visible.
Before the visit prior treatment response stays contextual, not final.
Diagnosis
Bilateral: failure to pass a 5 Fr suction catheter through either nostril. CT confirms diagnosis, measures thickness and type of atretic plate (osseous vs membranous). Bilateral = additionally requires CHARGE syndrome evaluation: cardiac echo (coloboma-heart defect), ophthalmology, BAER, renal US. Prenatal diagnosis is increasingly made by fetal MRI. Unilateral: unilateral nasal discharge and obstruction since birth.
Treatment
Bilateral: first oral airway stabilisation (oral airway/McGovern nipple; intubation if needed). Definitive repair after medical stabilisation (weeks to months in CHARGE). Endoscopic transnasal perforation plus microdebrider enlargement plus silastic nasal stent for 4–6 weeks. Mitomycin C 0.02% reduces stenosis. Unilateral: elective at ≥2–3 months. Multidisciplinary planning for CHARGE.
Outcomes and Follow-up
Endoscopic repair primary success 85–90%. Restenosis 20–30% requiring re-dilation under GA 10–15%. CHARGE syndrome has significantly worse outcomes due to complex anatomy and poor tissue healing. Long-term surveillance: nasoendoscopy every 6 months for 2 years. Infant endoscopy requires paediatric ENT and anaesthesia specialist experience due to technical difficulty.
When to Seek Care
Bilateral choanal atresia is a neonatal emergency; the neonate must be directed to the emergency department with paediatric ENT and neonatal intensive care support. Unilateral: unilateral nasal discharge since birth, difficulty breathing while feeding, or recurrent unilateral childhood sinusitis are situations requiring ENT referral.
