“…Scarring of the mucosa after irradiation may cause occlusion of the sinus ostium, which leads to formation of mucocele (10). Sphenoidal sinus mucoceles developing after radiotherapy for NPC have been reported rarely.…”

Introduction:A mucocele is an epithelial-lined, mucus-containing sac that can fill the sinus completely and expand gradually. Mucopyocele is an infected mucocele.Case Report:We presented a case of left maxillary mucopyocele in a 58-year-old man that developed after radiotherapy for nasopharyngeal carcinoma. Computed tomography scan showed opacification of the left maxillary sinus expanding through the medial wall of the antrum with thinning and destruction of the adjacent structures. Endoscopic marsupialization of the lesion and left partial maxillectomy were performed. The cystic mass had yellowish thick mucopurulent fluid that was completely drained.Conclusions:A few cases of sphenoid sinus mucocele as a late complication of radiation therapy have been reported. Maxillary mucocele and mucopyocele can be considered as one of the late complications of radiotherapy to head and neck as a result of occlusion of sinus ostia by scarred mucosa.

“…In the 2 patients with a contrast-enhancing sphenoid sinus mass, there was no large bony defect in the sphenoid sinus floor, thereby preventing any decompression into the nasopharynx, and in both cases the sphenoid sinus showed progressive expansion (Fig 6). Simple mucoceles have been reported previously as a complication of radiation therapy for nasopharyngeal carcinoma [6][7][8][9] and are believed to result from obstruction by scar tissue. It is postulated that the expansion of the sphenoid sinus in this study was caused by ongoing chronic inflammatory and radiation changes obstructing the sinus ostium.…”

“…[3][4][5] Rarely a mucocele may form in the sphenoid sinus. 6 However, there are some patients who go on to develop severe delayed radiation effects resulting in the formation of unusual nonmalignant polyps and masses (NMPMs) in the nasopharynx and sphenoid sinus. These radiation-induced injuries cause both clinical and radiologic problems with distinction from recurrent cancer, as well as being a cause of serious morbidity and even mortality.…”

BACKGROUND AND PURPOSE:The development of a new polyp or mass in the radiation field of a previously treated carcinoma is usually an ominous sign of a recurrent cancer, but rarely may it be caused instead by a nonmalignant process. The purpose of this study was to document the MR appearance of unusual nonmalignant polyps or masses (NMPMs) in the nasopharynx and sphenoid sinus arising after radiation treatment of nasopharyngeal carcinoma.

“…Submucosal oedema may result from allergic rhinitis causing ostia narrowing with obstruction; ostia obstruction may also be due to chronic sinusitis, polyposis, or both [50]. Sphenoid sinus mucocele formation has been reported as a possible late complication of radiotherapy to the head and neck [51] . Radiation causes scarred mucosa which may occlude the sinus ostium.…”

Paranazal sinüsün benign genişleyen lezyonu olan mukoseller, daha çok 5. ve 6. dekkatta görülür. Sinüs mukoselleri; travma, enflamasyon, mukoselin kitle etkisi, idiopatik ve iatrojenik nedenlerle ostiumun obstriksiyonu ile oluşur. En sık frontal sinüste, daha sonra sırasıyla etmoidal, maksiller ve sfenoid sinüste görülür. Mukoselin etkilediği sinüse ve mukoselin büyüklüğüne göre nazal, oftalmolojik, intrakranial ve kozmetik semptomlar görülebilir. Mukopiyosel mukosel içeriğinin enfekte olmasıyla meydana gelir ve menenjit, orbital selülit ve osteomyelite neden olabilir. Günümüzde mukosel tedavisinde ilk tercih edilecek yöntem endoskopik sinüs cerrahisi ile marsipilizasyondur. Ancak frontal sinüs mukosellerinde frontal sinüsün anterior duvarında erezyon mevcutsa veya mukosel çok lateral yerleşimli ise eksternal yaklaşım da tedavi alternatifi olabilir.
