Rarely, such tumors may appear in the external auditory canal. There are only 14 described cases of the syringocystadenoma papilliferum in the external auditory canal in the Medline database. In this study, we present the first reported case of syringocystadenoma papilliferum arising in the modified radical mastoidectomy and occurring 12 years after ear surgery. A 26-year-old man was admitted to our clinic with complaints of discharge from the left ear, ear fullness, and hearing loss. These symptoms had been worsening for 3 years. Twelve years previously, he had undergone modified radical mastoidectomy by Bondy due to a cholesteatoma. Otoscopic examinations revealed otorrhea and a reddish mass measuring 1 × 0.8 cm arising from the tegmen tympanum and fundus of the mastoid cavity. A surgical biopsy was conducted with local anesthesia in the medical outpatient clinic, and it revealed syringocystadenoma papilliferum. A tumor resection was performed with a retroauricular approach. The bone attachment of the tumor was drilled out, and the ear cavity was covered with a mashed split skin graft. The ear cavity healed, and no tumor recurrence was observed during a 9-month follow-up period. Our case and literature analysis of previously described cases led to the conclusion that cases of syringocystadenoma papilliferum of the external auditory canal may be associated with different medical histories, age distributions, and origins than other syringocystadenoma papilliferums of the head and neck region. Tubular adenoma may occur together with syringocystadenoma papilliferum in 20% of cases. Malignant transformation of syringocystadenoma papilliferum may occur but is extremely rare. Computed tomography imaging may predict malignancy of the tumor. Tumors specific to the external auditory canal may occur in the modified radical mastoidectomy after middle ear surgery.</p>","PeriodicalId":54793,"journal":{"name":"Journal of International Advanced Otology","volume":"18 6","pages":"544-547"},"PeriodicalIF":1.0,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/cc/43/jiao-18-6-544.PMC9682761.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40462108","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: We describe our experience with 12 patients with complex jugular paragangliomas diagnosed in our institution from January 2013 to June 2020. The main outcomes included tumor control, complications, and function of facial nerve and lower cranial nerves, postoperatively. Results : Gross-total resection was achieved for 9 (75%) patients, and subtotal resection was achieved for 3 (25%) patients. The surgical tumor control rate was 100% after a mean follow-up of 45.5 months (range, 13-111 months). Postoperatively, 10 patients (83.3%) obtained unchanged or improved facial nerve function. However, new lower cranial nerve deficits occurred in 2 patients (16.7%) due to surgical removal of the concurrent vagal paraganglioma and scar tissue enclosing the IX and XII nerves. Conclusion: Our refined surgical techniques, including tension-free anterior facial nerve rerouting, sigmoid sinus tunnel-packing, and push-packing techniques, could be a choice for the treatment of complex jugular paragangliomas to achieve tumor control and cranial nerves preservation. A 2-stage surgery should be applied to minimize the risk of bilateral cranial neuropathies and the influence on cerebral circulation in patients with bilateral paragangliomas. The preoperative endovascular intervention such as coil embolization or internal carotid artery stenting can be employed for the management of paragangliomas with internal carotid artery-associated lesions.","PeriodicalId":54793,"journal":{"name":"Journal of International Advanced Otology","volume":"18 6","pages":"488-494"},"PeriodicalIF":1.0,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/3d/bf/jiao-18-6-488.PMC9682854.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40673930","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
