Underlay myringoplasty: comparison of human amniotic membrane to temporalis fascia graft.
(1/15)
Human amniotic membrane as a homograft material was compared to temporalis fascia to close tympanic membrane perforations in 50 patients with chronic otitis media. Human amniotic membrane was used in 20 patients while temporalis fascia was used in the remaining 30. Anatomical closure of the perforation and reduction of the air-bone gap was measured. The graft uptake showed a 65% success rate for the amniotic membrane and 56.7% for the temporalis fascia at 3 months post-operatively. Significant closure of air-bone gap was observed in the human amniotic group. These results indicate comparable outcomes between human amniotic membrane and the temporalis fascia graft. (+info)
Surgical audit in day care myringoplasty.
(2/15)
Day-case surgery is preferred for adults, allowing post-operative fast recovery in family environment and support. Myringoplasty using the traditional method of underlay temporalis fascia or tragal perichondrium is usually performed as an in-patient. From 2003 to 2004, 22 myringoplasty procedures were performed in a dedicated day surgery unit at the Hospital Melaka. We report the retrospectively review of the outcome results of these procedures. None of the patients need admission overnight. There were no surgical or anesthetic complications noted and this series suggests that day-case surgery is a safe and desirable practice for patients undergoing myringoplasty. However, there should be the facility for admission if required. (+info)
Cochlear tolerance of Nd:YAG laser myringotomy.
(3/15)
AIM: The objective of this study was to assess whether Nd:YAG laser myringotomy has a negative effect on the cochlea. MATERIALS AND METHODS: Ten adult guinea pigs with a normal Preyer's reflex were treated by myringotomy with an Nd:YAG laser (power output 8-10W) under surgical microscopic guidance. Preoperative and immediately postoperative hearing tests were performed using auditory brainstem response. The cochlear hair cells were investigated by scanning electron microscope (SEM). RESULTS: The mean postoperative hearing threshold of the auditory brainstem response showed an insignificant elevation. SEM findings revealed normal outer and inner hair cells after laser myringotomy. CONCLUSION: No negative effect of Nd:YAG laser myringotomy on the cochlea was found. From these results, it can be concluded that the Nd:YAG laser is safe and effective for myringotomy. (+info)
Chorda tympani nerve function after myringoplasty.
(4/15)
This is a cross-sectional study design aimed to determine the prevalence of Chorda Tympani Nerve (CTN) injury and related symptoms following myringoplasty. Thirty patients were included in this study. The methods used were measuring taste thresholds using electrogustometer to map taste threshold on the anterior two-third of the tongue on the operated side with the non operated side as the control. Reading is taken when the subject experiences sour/metallic taste. All corresponding threshold values and findings were recorded and compared to control. Results showed 50% of patients had elevated threshold levels suggestive of CTN injury. However, none of the patients reported subjective taste loss. This study concludes that the prevelance rate of CTN injury in post myringoplasty patients is about 50% but this is not associated with altered taste sensation. (+info)
Repair of the tympanic membrane with urinary bladder matrix.
(5/15)
INTRODUCTION: To date, myringoplasty conducted under the operating microscope has been found to have its limitations. With the introduction of the endoscope into other branches of surgery, there have been attempts at its utilisation in otology. METHODS: Endoscope-assisted myringoplasty was carried out in 50 patients aged 18-45 years using the temporalis fascia graft. The middle ear was examined through perforation in order to exclude cholesteatoma. RESULTS: The overall success rate of the graft uptake and improvement in conductive deafness as air-bone gap closure was achieved in 80 percent of cases. CONCLUSION: Endoscopic myringoplasty was found to be equally effective, less morbid and very cost-effective in small central perforations. However, it is not applicable in all cases, especially in those with large perforations. (+info)
Otitis externa and myringitis due to demodicidosis.
(7/15)
We report on an 84-year-old woman with chronic pruritic otitis externa and myringitis. Microbiological and mycological investigations failed to establish the cause, but histology revealed a large amount of Demodex mites. Topical treatment for this ectoparasite resulted in a complete remission. The myringitis was eventually treated successfully with myringoplasty. To the best of our knowledge this is the first case report on Demodex-induced otitis externa and myringitis. (+info)
