“…Very large polyps may descend into the oropharynx and cause a foreign body sensation. As previously noted, the presentation of bilateral nasal obstruction is possible due to expansion of the polyp from one choanae to the other, however true bilateral ACP is extremely rare [15].…”

Antrochoanal polyp (ACP) is a benign unilateral polyp, originating from the maxillary sinus and expanding through the accessory or natural ostia into the nasal cavity and choanae. It has a 2: 1 male predominance and is more common in children and young adults. The exact pathophysiology is unclear, and it is thought to have less of the inflammatory reactions as opposed to typical bilateral nasal polyps which are commonly seen in diffused chronic rhinosinusitis. The presenting symptoms of ACP are unilateral nasal obstruction and rhinitis. Epistaxis, pain, and foul-smelling secretions are not typically seen and point towards a different etiology. Diagnosis is mainly clinical via endoscopic examination and supported by Computed tomography (CT) imaging. In CT images the three components of the polyp can be identified; an intramaxillary portion, intranasal and choanal components. Treatment is surgical, where Endoscopic sinus surgery (ESS) is the main technique used with other assisting approaches to reach the more challenging anterior and inferior areas of the maxillary sinus. Successful resection depends on complete removal of the intramaxillary component of the polyp to avoid polyp regrowth. The typical histologic characteristics are cyst formation, fibrosis and squamous metaplasia that are significantly more common in ACP than diffused nasal polyps.

“…Although ACPs are most often unilateral, bilateral cases have also been reported in the literature. [5][6][7][8][9] Endoscopic examination and CT are the gold standard diagnostic tools. However, in the pediatric age group, contrast-enhanced MRI is necessary to detect pathologies such as angiofibroma, encephalocele, and meningoencephalocele.…”

An antrochoanal polyp (ACP), also known as Killian's polyp, is a solid, benign, polypoid lesion originating from the inflammatory mucosa of the maxillary sinus and extending into the nose, choana, and nasopharynx through the maxillary ostium. ACP is rare, and is usually seen in adults. Cystic fibrosis is an important risk factor in young patients. Although the etiology is not completely known, allergies and sinonasal disease play an important role. The condition is usually unilateral but may also be bilateral. A 13-year-old girl presented with nasal obstruction, snoring, and episodes of obstructive sleep apnea. Examination revealed an ACP. Endoscopic sinus surgery was performed with a transoral approach to remove a giant ACP extending to the epiglottis.

“…Diagnosis difficulty is generally due to the scarcity of this disease, and the similar clinical presentation of more frequent differential diagnosis [1][2][3][4]. Management is generally surgical through functional endoscopic sinus surgery, and outcome is great with clinical improvement and no recurrence in follow-up [8][9][10][11][12][13][14][15][16][17][18][19][20][21].…”

Background Antrochoanal or Killian polyp is a rare polyp of the maxillary sinus in adults. It is generally unilateral, implanted on the lateral wall of the maxillary sinus upon the uncinate process. Bilateral cases are very rare; only 14 cases have been cited from 1980 to 2020. Case presentation Our patient presented with a complete bilateral nasal obstruction, this symptom persisted for more than 10 years, with a perceived prolapse in his throat in the last 4 months. Anterior rhinoscopy showed a polyp that took up the totality of his nasal vestibule. Posterior rhinoscopy showed a polyp bulging behind the uvula. The challenge in this case is related to diagnosis decision; conditions with the same clinical presentation are several. Diagnosis was established through the clinical, radiological, and endoscopic aspects, and confirmed by histological findings. Management was obtained through functional endoscopic sinus surgery; no recurrence was noted in the 12-month follow-up, and clinical signs had completely subsided. Conclusion Diagnosis in bilateral forms of Killian polyp is perplexing; however, its management is generally simple, with excellent outcome. We report the case of the 15th patient along with a systematic literature review discussing bilateral Killian polyps, illustrated by a rare case of enormous bilateral antrochoanal polyps.
