Background and Objectives: Inlay butterfly cartilage tympanoplasty makes the graft easy, and reduces operating time. The present study aimed to investigate the outcomes of microscopic versus endoscopic inlay butterfly cartilage tympanoplasty. Subjects and Methods: In this retrospective study, the outcomes of 63 patients who underwent inlay butterfly cartilage tympanoplasty with small to medium chronic tympanic membrane perforation were evaluated. Twenty-four patients underwent conventional microscopic tympanoplasty and 39 underwent endoscopic tympanoplasty. The outcomes were analyzed in terms of the hearing gain and graft success rate. Results: The surgical success rate was 95.8% in the patients who underwent conventional microscopic tympanoplasty and 92.3% in those who underwent endoscopic tympanoplasty. In both groups of patients, the postoperative air-bone gap (ABG) was significantly lower than the preoperative ABG. There were no significant differences between the preoperative and postoperative ABG values in either group. Conclusions: Endoscopic inlay tympanoplasty using the butterfly cartilage technique appears to be an effective alternative to microscopic tympanoplasty and results in excellent hearing.

Even through the methods of improving hearing are widely practiced in Korea, with its 30 years of history, there are many different opinions regarding the selection of surgical technique and the materials to be used in tympanoplasty. Also there are varying standards of postoperative evaluations. Therefore, we have done research to evaluate hearing improvement which in one of the objective of the middle ear surgery. The research was conducted for one year, January to December 1980. This research compared the level of hearing improvement after tympanoplasty, according to materials used in tympanoplasty and collumelization. Following are the data we have obtained; 1) Total number of cases we have reviewed were 306. Out of this, 35% of the cases were tympanoplasty type 1, 12.7% of the cases were collumelization with mastoidectomy, and 11.9% of the cases received collumelization without mastoidectomy. 2) We have conducted audiometry on 41.1% of the tympanoplasty type 1, 64.1% of the collumelization with mastoidectomy, and 45.7% of the collumelization without mastoidectomy. 3) We have observed above 11 dB hearing improvement in 70% of the tympanoplasty type 1, 36% of the collumelization with mastoidectomy, and 44% of the collumelization without mastoidectomy. 4) Over 11 dB decrease of air-bone gap in 61% of the tympanoplasty type 1,32% of the collumelization with mastoidectomy, and 63% of the collumelization without mastoidectomy. 5) If we look at the hearing improvement according to the materials used in the tympanoplasty, there was above 11 dB improvement of the air conduction in 63% with cartilage and 54% with fascia. In air-bone gap, 56% with cartilage and 52% with fascia. 6) If we look at the hearing improvement according to the materials used in the collumelization, there was above 11 dB improvement in 50% with cartilage, 14% with homograft, 55% with autograft. In air-bone gap, 56%, 21%, and 55% respectively.

The aim of ear operation is to cease otorrhea and to restore hearing. The ceasation of otorrhea and the graft of tympanic membrane are reached to successful stage, and yet hearing restoration process still remains further to need a matter of development. Authors carried out 67 cases hearing restoration operation among 154 patients who had been undertaken mastoid-tympanoplasty during period of Feb. 1978 through March 1979. 54 cases have been followed for this study among 67 cases hearing restoration operation. The used material of operation are almostly incus and some cases with TORP. This paper is dealing with its surgical method and postoperative audimetric study.

Since 1968, we have performed intact canal wall tympanoplasty with mastoidectomy and reported its methods and results on several occasions. We also reported ossicular reconstruction for hearing improvement after intact canal wall tympanoplasty with mastoidectomy. Many problems were noticed, so several variable operation methods were performed. This paper deals with the following: A checked up of hearing progress after ossicular reconstruction with a 93 cases out of a total 153 cases who had undergone this operation. This covered a period of January, 1973 to February, 1979 in our Department of Otolaryngology.

Background and Objectives: To assess whether the audiological and clinical outcomes of type 0 tympanoplasty (T0) performed using cartilage were comparable with those of ossiculoplasty in patients who underwent canal wall down mastoidectomy (CWDM). Subjects and Methods: This study included patients who had chronic otitis media with cholesteatoma and underwent CWDM with ossiculoplasty involving partial ossicular replacement prosthesis (PORP), total ossicular replacement prosthesis (TORP), or T0. Anatomical success rates and hearing outcomes were analyzed. Results: Seventy-two patients were included in this study; 29 of them underwent CWDM with T0, 27 underwent CWDM with PORP, while 16 underwent CWDM with TORP. The difference in mean improvement in the air-bone gap (ABG) between the groups was not significant. The differences in the rates of ABG closure to ≤10 dB HL (p=0.030) and ≤20 dB HL (p=0.029) were significant. There were significant differences in improvements in the ABG at 3 kHz among the PORP, TORP, and T0 groups. Conclusions: The audiological outcomes of CWDM with ossiculoplasty seemed to be better than those of CWDM with T0 with no significant difference in the incidence of complications following ossiculoplasty and T0.

There are a few case reports describing persistent seizure following propofol. A 45-year-old female underwent operation of mastoidectomy and tympanoplasty. She had no personal or family history of epilepsy. Anesthesia was induced with propofol and rocuronium, and maintained with sevoflurane-remifentanil after tracheal intubation. Any event was not noted during surgery. Seizure-like movement and shivering were developed after surgery in recovery room. Symptom was relieved by benzodiazepines, especially lorazepam. She was discharged in the 9th postoperative days without any sequelae.
