Objective We aim to demonstrate inner ear damage caused by drilling in the early period. Healthy contralateral ears of patients who underwent mastoidectomy using drill or tympanoplasty without using drill were compared. Methods A total of 38 patients (mastoidectomy: 22, tympanoplasty: 16) who were diagnosed as chronic otitis media and were scheduled for surgery were included. Distortion produ...
Objectives: To compare the results of tympanoplasty alone and tympanoplasty with cortical mastoidectomy in chronic suppurative otitis media (CSOM) patients with sclerotic bone in terms of graft uptake, perforation closure, improvement in hearing and disease eradication. Study Design: Retrospective study of patients at tertiary referral hospital. Method: 50 cases of non-cholesteatomatous chronic...
With this optical home network solution associating an NxN multimode architecture and CWDM technology, various applications and network topologies are supported by a unique multiformat infrastructure. Issues related to the use of MMF are discussed.
Four Channel DFB Laser Array Based on the Reconstruction-Equivalent-Chirp Technique for CWDM Systems
We report the first experimental realization of four-channel DFB laser array with equivalent phase shift (EPS) based on the reconstruction-equivalent-chirp (REC) technique for CWDM systems. OCIS codes: (140.0140) Lasers and laser optics; (140.5960) Semiconductor lasers
OBJECTIVE Candidates for revision tympanoplasty have experienced at least one failed attempt at repair of the tympanic membrane and are, therefore, at higher risk for subsequent repair failure. The adjunctive use of mastoidectomy with tympanoplasty in those patients with noncholesteatomatous chronic otitis media is often used to decrease the risk for subsequent failure. However, at this institu...
OBJECTIVE In spite of declining prevalence chronic suppurative otitis media without cholesteatoma (CSOM) still poses a significant health problem. Randomized clinical trials comparing medical and surgical intervention are not available. Hence, the treatment of CSOM is almost exclusively based on empirical experience. The purpose of the present study was to evaluate the long-term effects of mast...
