The Efficacy of DW and T1-W MRI Combined with CT in the Preoperative Evaluation of Cholesteatoma.

Objective: This study aims to assess the efficacy of diffusion-weighted (DW) and T1-weighted (T1W) magnetic resonance imaging (MRI) combined with high-resolution computed tomography (HRCT) (together as DW-T1W-CT) in the preoperative evaluation of the presence and extent of cholesteatoma, which helps determine whether a patient is suitable for transcanal endoscopic ear surgery (TEES).

Methods: This retrospective study included 35 patients (18 male and 17 female) aged from 2 to 81 years diagnosed with chronic otitis media with or without cholesteatoma, who had received surgical treatment and a preoperative MRI and HRCT during the period of December 2015 to December 2020 at Cathay General Hospital. We compared the preoperative DW-T1W-CT findings with the intraoperative findings and final pathologic diagnosis.

Outcome of Septoplasty with Inferior Turbinectomy as an In-patient or Out-patient Procedure.

The study aimed to compare the surgical outcomes of septoplasty with inferior turbinectomy between in-patient and out-patient groups. A total of 152 patients who underwent septoplasty with inferior turbinectomy between May 2012 and February 2013 were retrospectively reviewed and divided into in-patient group and out-patient group. The two groups were compared in three aspects: (i) consumption of medical resources, including National Health Insurance payments, patient surcharges, and total surgical expenses; (ii) prognostic indicators; and (iii) post-operative complications.

A retrospective comparative study of endoscopic and microscopic Tympanoplasty.

Background: This study compares endoscopic and microscopic tympanoplasty for the treatment of chronic otitis media (COM) without cholesteatoma.

Methods: This retrospective study included 153 ears (139 patients) treated surgically (endoscopic or microscopic tympanoplasty) for COM in the absence of cholesteatoma at our hospital between January 2008 and October 2015. The adoption of transcanal endoscopic ear surgery (TEES) or microscopic ear surgery (MES) was divided temporally (before and since 2014).

The anatomic applicability of transcanal endoscopic ear surgery in children.

Objective: The feasibility of TEES in dealing with pediatric middle ear disease is still under investigation. The goal of this study was to compare anatomical dimensions of the EAC between children and adults, and to analyze the anatomic applicability of TEES in children.

Methods: Forty pediatric (18 years old and younger) and 20 adult patients who received TB-HRCT to evaluate middle ear conditions were enrolled from December 2010 to December 2015.

Cervical posterior triangle castleman's disease in a child - case report & literature review.

The most prominent sites of Castleman's disease (CD) are the thorax (mediastinum or lung hilum) and abdomen. It rarely occurs in the cervical area and only one case has been reported in the posterior triangle of the neck. We report a new case of cervical posterior triangle CD in a child.

Endoscope-assisted KTP laser sinus clear-out procedure for recurrent ethmoid polyposis.

Background Data And Objective: Surgery for recurrent sinusitis with diffuse polyposis is challenging since tortuous sinus anatomy and bleeding tendency can make revision surgery particularly difficult. We report the efficacy in using KTP laser under the assistance of endoscope to perform sinus clear-out procedure for patients with recurrent ethmoid polyposis.

Materials And Methods: Thirteen patients with recurrent ethmoid polyposis underwent this procedure between November 1996 and July 2000.
