Radiological Examinations of Inferior Turbinate in Patients with or without Deviated Nasal Septum by Using Computed Tomography / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: The aim of this study was to analyse the radiological anatomic dimensions of the inferior turbinate in patients without deviated nasal septum and compare it to those in the patients with deviated nasal septum using computed tomography. SUBJECTS AND METHOD: The OMU CTs of 98 patients, 196 nostrils with or without deviated nasal septum were evaluated (control group: 42 patients, deviated septum group: 56 patients). The analysis of the CT scans contained the mucosal and bony length, mucosal width of the turbinate and the anterior and posterior mucosal overlay. And also evaluated the cross-sectional area and the type of inferior turbinate bone. RESULTS: All subjects were divided into three groups: the concave, convex, and control groups. The correlations of fifteen measuring points such as anterior, middle and posterior medial mucosal thickness, total width, bone width, medial mucosa width of inferior turbinate, and area of inferior turbinate bone were significantly different among the groups (concave side>con-trol group>convex side). Of the demographic factors, age was negatively correlated with mucosa and bone length. Types of inferior turbinate bone were as follows: lamella type (38%), combined type (37%), compact type (25%). CONCLUSION: There were statistical differences in some measured anatomical points among the concave, convex, and control groups. Greater septum deviation was correlated with greater degree of hypertrophysm of the inferior turbinate. The age of patients showed negative correlation with inferior turbinate length. Most frequent type of inferior turbinate was lamella type. The results of this study may provide important information when considering turbinate surgery.

A Case of Transoral Endoscopic Excision of Recurred Synovial Sarcoma in Pyriform Sinus / 대한이비인후과학회지

Synovial sarcoma in head and neck is an extremely rare cancer. Symptoms may occur depending on the location of tumor. Synovial sarcoma is divided into two main phenotypes-biphasic and monophasic. Surgical excision including optimal resection margin is generally recommended as a standard treatment of synovial sarcoma, if the tumor is resectable. Standard adjuvant therapy of synovial sarcoma has not been established yet. Recently, we have experienced a case of recurrent synovial sarcoma in pyriform sinus without regional or distant metastasis after initial resection of tumor. We successfully performed endoscopic excision of recurred tumor and obtained clear resection margin. We followed up the patient without any adjuvant therapy for 2 years. We report this rare case with literature review.
