Description

A 4-year-old boy presented with a lifelong history of nasal obstruction, mouth breathing and snoring. His parents denied any associated rhinorrhoea, sneezing, facial pain, facial swelling, epistaxis, epiphora or sinus infections. Skin prick testing was negative for all environmental allergens. On physical examination, the bilateral nares were completely occluded by smooth, compressible masses that prevented complete examination of the nasal cavities (figure 1). The masses did not change in size when either of the internal jugular veins were compressed. CT scan of the sinuses without contrast showed bilateral soft tissue densities obliterating the nasal cavities, extending from the nasal vestibule to the posterior nasopharynx. The masses obstructed the paranasal sinus outflow tracts and bilateral Hasner’s valves. All the pneumatised ethmoid, maxillary and sphenoid sinuses demonstrated significant mucosal thickening (figure 2). There was no bony erosion of the skull base, lamina papyracea or bony septum, and no bony expansion of the sinuses or nasal bones was seen.

There is soft tissue thickening of the bilateral maxillary sinuses. No bony erosion or intracranial continuity is seen.

The final diagnosis was severe bilateral inferior turbinate hypertrophy completely filling the nasal cavities. Initially, aggressive medical management was attempted with a regimen of topical nasal steroid spray, nasal saline spray, oral steroid taper, oral antihistamine and a 3-week course of oral azithromycin. However, delivery of topical medications to the patient’s nasal cavity proved difficult due to significant obstruction and persistent dripping of medication out of the nose, and no clinical improvement was seen. Due to the severity of both nasal obstructive symptoms and severe reactive sinonasal inflammatory changes, the decision was made to proceed with staged surgical intervention that first involved both mucosal and submucosal reduction of the bilateral inferior turbinates, bilateral maxillary antrostomies, bilateral anterior ethmoidectomies, adenoidectomy and placement of silastic sheeting to prevent adhesion formation. In the second stage 1 week later, the silastic was removed, but persistent inflammatory changes were observed in the sphenoethmoidal recesses, so the decision was made to proceed with completion posterior ethmoidectomy and sphenoidotomy. One month postoperatively, his nasal airway appeared widely patent, and his mother reported significant improvement in nasal breathing.

The differential diagnosis of paediatric nasal masses is extensive and includes nasal dermoid cyst, glioma, encephalocele, nasolacrimal duct cyst, papilloma, chondroma, chordoma, meningioma, haemangioma, teratoma and reactive mucosal hypertrophy.1–3 More generally, paediatric nasal masses can be divided into congenital, inflammatory and neoplastic aetiologies. Occasionally, inferior turbinate hypertrophy can be so severe that it leads to reactive sinus disease,2–4 as was seen here. Nasal masses noted in the perinatal period are generally limited to the congenital type, but differential diagnosis broadens with increasing age and must include reactive and inflammatory lesions such as nasal polyps or mucosal hypertrophy.5 The diagnosis of nasal masses is made primarily through careful history and physical examination, with imaging indicated in cases where diagnosis is questionable or when there is concern for intraocular or intracranial connection. Overly aggressive biopsy should be approached with caution, as it can precipitate severe haemorrhage in vascular lesions or could trigger a severe central nervous system infection in cases of encephalocele.1

Despite being an entity that many otolaryngologists diagnose several times daily, severe inferior turbinate hypertrophy can sometimes represent a diagnostic challenge. Although intranasal steroids and antihistamines are considered first-line therapy, surgical intervention has been shown to be successful in severe cases.4 6 Using modern mucosal-sparing techniques, such as radiofrequency ablation and submucosal reduction, otolaryngologists can expect improvements in their patients’ outcomes even in the most extreme cases.

Patient’s perspective

Patient’s mother: For years, I could not get my child to breathe through his nose no matter how hard I tried. He would cry to me constantly complaining that he could not breathe, and that made me feel bad as a parent. It was hard for the entire family to go through. I started to feel like he would never get better on his own, so I brought him to the doctors, who took great care of him from the start. It took three surgeries to get him better. That was also hard on him and on me as a parent, but they were able to fix his breathing. It was a lot for him to go through, but he is so much happier now, and that is all that a parent could ever ask for.

Learning points

  • The differential diagnosis of nasal masses in the paediatric patient is extensive and any suspicious mass should be worked up thoroughly.

  • Despite being one of the most common diagnoses otolaryngologists make, severe hypertrophy of the inferior turbinates can unusually present with visible nasal masses, as was seen here.

  • Medical therapy with intranasal corticosteroids is considered first-line therapy, but in severe cases, surgery is required for complete resolution.
