RESUMO
A nasal polyp is a distinct mucosal pathology that obstructs the nasal cavity and paranasal sinuses, with various phenotypes and endotypes. Nasal polyps should be distinguished from inverted papillomas, squamous cell carcinomas, juvenile angiofibromas, lymphomas, and olfactory neuroblastomas. A choanal polyp is a solitary benign lesion that originates in the paranasal sinus and extends to the choana through the natural ostium of the sinus. Choanal polyps usually originate from the maxillary sinus; however, we recently experienced the case of 41-year old women with sinochoanal polyp originated from the ethmoid sinus. As choanal polyps can recur even after appropriate surgery, complete resection, including the surrounding mucosa at the site of origin, is required. Therefore, it is essential to consider anatomical differences in polypectomy. We recently diagnosed and successfully performed surgery on an ethmochoanal polyp; herein, we report our experience and present a literature review.
RESUMO
Background and Objectives@#Traditionally, transoral laser microsurgery (TLM) is commonly used to treat early glottic cancer. However, the long-term oncologic results have not been thoroughly investigated. Therefore, this study aimed to analyze long-term oncologic outcomes of TLM for early glottic cancer.Subjects and Method We retrospectively studied 132 patients who underwent TLM for early glottis cancer from January 2001 to August 2020. We assessed overall and disease-free survival according to the T classification and types of cordectomy proposed by the European Laryngological Society in 2007. @*Results@#Of the 132 patients, 125 were male and 7 female. The mean age was 61.6±9.3 years. We found 5 (3.8%), 112 (84.8%), and 15 (11.3%) patients staged as CIS, T1, and T2, respectively. For the cordectomy types, there were 6 in type I, 22 in type II, 83 in type III, 6 in type IV, 13 in type V, and 2 in type VI. Ten-year overall and disease-free survival rates were 99.2% and 87.1%, respectively. Overall and disease-free survival curves were not different according to different T classification and cordectomy types. @*Conclusion@#TLM is an excellent treatment modality for the long-term oncologic control of early glottic cancer.
