RESUMEN
A good graft material is the one which is easily available and harvestable, tough and is easy to be handling and survival is good. Both temporalis fascia and fascia lata graft satisfy all these criteria. Keeping all these factors in mind, the comparative study of temporalis fascia and fascia lata graft in tympanoplasty is undertaken. All the patient reporting to ENT OPD with tympanic membrane perforation who are fit for surgery were advised tympanoplasty or tympanoplasty with mastoidectomy were included in the study. Our observation and data analysis have shown that fascia lata is definitely better than temporalis fascia in terms of intactness of graft (95.1% in fascia lata and 90.24% in temporalis fascia) and PTA average improvement is higher in fascia lata graft (11.56 ± 5.005) as compared to temporalis fascia graft (10.32 ± 4.634) and ABG improvement is higher in fascia lata graft (2.7317 ± 1.118) as compared to temporalis fascia graft (2.634 ± 1.089). Fascia lata has better dimensional stability, easy handling and thickness of the graft and it provides more resistant to negative middle ear pressure. Hence, fascia lata is one of the good choices in otologist's armentorium for tympanoplasty graft material.
RESUMEN
Background: This study mainly focus on hearing loss pattern in CSOM patients undergoing tympanoplasty surgery or tympanomastoidectomy pre-operatively and analysis of the outcome of the surgery in terms of improvement in hearing (air-bone gap) after 3 months of the surgery. Methodology: All patients of age 15-65 years reporting to ENT OPD with ear discharge and decreased hearing were screened with detailed history, clinical examination and microscopic examination.110 cases of tympanic membrane perforation who were fit for surgery were advised tympanoplasty or tympanoplasty with mastoidectomy. Results: Our study shows that postoperative air-bone gap closure is maximum for cortical mastoidectomy type I tympanoplasty (14.03 dB), followed with cortical mastoidectomy with type II (12.2 dB), Type I tympanoplasty (11 dB), cortical mastoidectomy with type III (7.72 dB). Procedures combined with modified radical mastoidectomy showed a very poor mean improvement in our study. Conclusion: It is very difficult to predict the results preoperatively because outcome will depend on extent of involvement of middle ear cleft by the disease process which can only be assessed intraoperatively.
