The aim of this study is to evaluate the results of closure of big central and subtotal perforation by Tympanoplasty using underlay technique with Composite graft of tragal perichondrium supported by a ring of cartilage peripherally. Our hypothesis was that the cartilage support offers an extremely reliable method for reconstruction of the tympanic membrane in cases of advanced middle ear pathology and Eustachian tube dysfunction and also revision cases. Prospective study of patients undergoing tympanoplasty in big central and subtotal perforation with graft supported by a ring of cartilage peripherally between June 2016 and August 2016. Hearing results were reported using four frequency (500, 1000, 2000 and 3000) pure tone average air-bone gap. During the study period, composite graft comprising of tragal perichondrium and peripheral ring of cartilage prepared from ipsilateral tragus was used for tympanic membrane reconstruction in 30 patients. Overall graft take rate was 93.33%. Complications included residual perforation in 6.67%. Cartilage ring support offers an extremely reliable method for reconstruction of tympanic membrane in cases of high-risk perforation (big central perforation, subtotal perforation, anterior perforation of tympanic membrane, revision cases).
Introduction
Autologous reshaped Incus and Teflon partial ossicular replacement prosthesis (PORP) are commonly used for ossicular chain reconstruction. The present study attempts to assess the post-operative outcome with these two prostheses.
Materials and Methods
A Randomized prospective study was conducted in Tertiary referral care hospital to determine which material, among autologous reshaped Incus and Teflon partial ossicular replacement prosthesis (PORP) gives better postoperative hearing result in Ossiculoplasty.
Patients presenting at outpatients’ department with the clinical diagnosis of chronic otitis media with perforation or retraction. The study population consisted of a total of 50 patients. Ossiculoplasty with reshaped Incus or PORP was performed after Canal Wall Up mastoidectomy. Hearing results were measured by Air-Bone gap in PTA after 6 months of surgery.
Results
Selecting the criteria <20 dB ABG as success when Stapes superstructure is present, Incus has 64.29% success rate, whereas PORP has 31.81% success. Extrusion rate of different prosthesis shows PORP has 18.18% extrusion whereas autologous Incus has lower (7.14%) extrusion rate.
Conclusion
Among these two ossiculoplasty materials, autologous Incus gives better postoperative hearing gain and lower extrusion rate.
Introduction
Endoscopic Surgery has immense potential for middle ear surgery and is currently favoured by many surgeons. The 3 (vascular) Strips/ 3 Flap Tympanoplasty with operating microscope is popular but Endoscopic 3-Flap Tympanoplasty remains less explored. Hence this study was conducted to compare advantages and disadvantages of Endoscopic and Microscopic 3-Flap Tympanoplasty.
Materials and Methods
Forty two patients with large/subtotal perforation of tympanic membrane were divided into two equal groups (Group A & B). Endoscope was used in Group A, whereas, operating microscope in Group B. Temporalis fascia was the graft material in all patients. Patients were followed up for six months. Pre and post-operative audiograms, post-operative pain, graft uptake, time taken for surgery and intra-operative visualization convenience were compared.
Results
Mean Air-Bone Gap closure at the end of six months was 9.23 dB (SD-0.88 dB) in the endoscope group and 8.95 dB (SD-0.66 dB) in microscope group whereas the graft uptake rate was 95.2% and 90.2% respectively. Post-operative pain, cosmesis, ease of doing surgery and time taken for surgery were better in ‘Endoscope’ as compared to ‘Microscope’ group.
Conclusion
The three flaps produce adequate exposure in very large or subtotal perforations, very thin anterior rim or with anterior bony overhang. Results in terms of mean hearing gain and graft uptake were comparable. In terms of morbidity (post-op pain), recovery (return to routine activity), mean duration of surgery and cosmesis, endoscopic surgery produced better outcome.
