Choanal Polyps: An Evaluation of 53 Cases

Abstract

Endoscopic approach for complete removal of the CPs is an extremely safe and effective procedure. It should be focused on the detection of the exact origin and the extent of the polyp to prevent recurrence.

Update on Select Benign Mesenchymal and Meningothelial Sinonasal Tract Lesions

“…Patients tend to have a longer duration of symptoms with ACPs than with SNIPs [63]. While the vast majority of ACPs are unilateral, synchronous bilateral involvement may be observed, along with bilateral maxillary sinusitis [61]. It is not uncommon to have concurrent SNIPs, allergic rhinitis, chronic rhinosinusitis and/or turbinate hypertrophy.…”

“…The stalk of attachment within the medial wall is not usually identified by imaging, but a large, pedunculated polyp will expand into and fill the nasal cavity and/or pharynx [55,62,64,65]. Uncommonly, choanal polyps will arise from the sphenoid or ethmoid sinus, referred to as sphenochoanal or ethmochoanal polyps, revealing a stalk of attachment in the named sinus [61]. Conservative combination endoscopic (Functional Endoscopic Sinus Surgery: FESS) and open surgery (miniCaldwell procedure) to include the stalk and sinus contents, seems to yield the lowest risk of recurrence [55,60,64], especially if the point of attachment cannot be identified.…”

“…ACPs tend to develop in younger patients than classical SNIPs, affecting teenagers and young adults (mean 24-28 years) [55,60]. Symptoms are non-specific, most commonly including nasal obstruction and rhinorrhea [55,[60][61][62][63]. Patients tend to have a longer duration of symptoms with ACPs than with SNIPs [63].…”

Paediatric traffic accident and obstructive sleep apnoea by antrochoanal polyps: Case report and literature review

“…Concerning the association of ACP with OSA only three documented cases have been published so far [5,14,16]. Many authors list obstructive sleep disorders (loud snoring, sleep apnoea) as possible manifestations of ACPs [23,30,[33][34][35]. But in none of those studies the evaluation of diagnosis becomes evident and the distinction between loud snoring and full blown OSA has not been elaborated.…”

Endoscopic surgery in pediatric recurrent antrochoanal polyp, rule of wide ostium

“…The common site is posterior wall followed by inferior and lateral walls. It should be focused on the detection of the exact origin and the extent of the polyp to prevent recurrence [16,18]. Bozzo et al [19] observed two recurrences, both in pediatric cases who evidently underwent an incomplete surgical removal of antral mucosa at its inferior aspect, probably due to the fear of damaging the teeth buds.…”
