Comparative Study of Outcome of Tympanoplasty by Postauricular and Permeatal Approach

Background: As from time of residency, tympanoplasty is the most common operation performed by an otolaryngologist. Because of the continuing efforts of otologists all around the world to produce the maximum surgical outcome, significant improvements in this surgical method have developed during the middle ages. Objective: The aim of the study was to compare the outcome of Tympanoplasty in Postauricular and Permeatal Approach.Methods:A total of 74 patients between the age group 15 to 44 years who were attending the ENT OPD, suffering from Chronic Suppurative Otitis Media (CSOM) were selected on the basis of type of perforation and their workup was done to assess the candidature for tympanoplasty. Comparative analysis between the two groups were done based on analysis using SPSS 24 software version. The level of significance was set to 5% (p < 0.05).Results:A total of 74 patients were included in the study and the overall graft take was 76.92% in cases of Permeatal technique as compared to 91.66% in the case of postaural underlay technique. The complication of postaural approach higher than Permeatal approach. There was a difference in hearing improvement with majority of the cases improving to the range of 10-22 dB in Permeatal technique compared to 08-18 dB in Postaural Underlay technique.Conclusion:In terms of complications and hearing improvement, the Permeatal method outperforms the Postauricular Approach, however the graft takes a higher percentage in the Postauricular Approach than the Permeatal Approach.

Background: The main objective of the study was to assess and compare the graft uptake, hearing improvement, complications in large, subtotal, and anterior moderate perforations by each technique viz; superiorly based circumferential tympanomeatal flap tympanoplasty (STT)/full cuff and anterior anchoring flap tympanoplasty (AAT)/anterior tucking. Methods: In our study of 30 cases age group in the range of 10 years to 60 years. The mean air bone gap for the 8 patients with anterior moderate perforation was 31.75 db, for 17 patients with large central perforations was 38.75 db and for 5 patients with subtotal perforations was 41.4 db. Results: Mean air bone gap closure after 3 months of surgery in the STT group was 21.4 db while that after 6months of the surgery for the same group was 22.06 db. Mean air bone gap closure after 3 months of surgery in the AAT group was 18.2 db while that after 6months of the surgery for the same group was 18.73 db. Conclusions: Comparing the air bone gap closure in patients who underwent surgery by AAT and STT technique we found that there is no statistical difference. Both techniques (viz: superiorly based circumferential tympanomeatal flap tympanoplasty and anteriorly anchoring flap tympanoplasty) can be used for the repair of large, subtotal, and anterior tympanic membrane central perforations in chronic suppurative otitis media of mucosal type.

The Universe

A comparative study of the mythological picture of the world, early forms of religion allows us to identify common features characteristic of the worldview and spiritual guidelines of mankind as a whole. These features can be traced in archaic ideas about the structure of the universe, in understanding their spiritual and bodily essence, the infinity of God and the eternity of the soul, the relationship and interdependence of life forms in the world. This allows us to assert the thesis of the unity of mankind in its spiritual origins, despite racial and ethnic diversity. In the process of a comparative analysis of mythology, early forms of religion, the concept of God, the pantheon and the function of the gods, similar moments and ethnological specifics of understanding the essence of the soul and reincarnation in totemistic beliefs, in cosmological and theogonistic concepts are revealed.The author also analyzes the role and significance of the cult of ancestors, traces the evolution of the idea of proto-monotism (the creative function of Tengri and Brahma, the intention of henotheistic faith) and its place in religious knowledge.

Abstract Background Tympanoplasty is the well-established procedure for closure of perforations of tympanic membrane. Study Design This study was a prospective comparative study. Objective The objective of this study was to compare the hearing improvement and graft uptake rate between dry and wet tympanoplasty performed on tubotympanic type of chronic suppurative otitis media. Materials and Methods One hundred forty patients with tubotympanic type of chronic otitis media were selected and categorized into dry and wet ears. Tympanoplasty was performed using temporalis fascia by underlay technique in all cases. Postoperatively, graft uptake rate and hearing improvement were analyzed. Results The graft uptake rate was equal in both dry and wet ears, which was statistically insignificant. There was no statistically significant difference in the hearing improvement between the dry ears and wet ears (χ – 2.39, p = 0.122). Conclusion Factors such as age, sex, and status of the contralateral ear and wet ear did not have any impact on the postoperative graft uptake of tympanoplasty. There was no difference in the graft uptake between the dry and wet ears and there was no statistically significant difference between hearing improvement in both and wet ears.

Chinese postgraduate professional degree education has undergone 26 years of development, and has achieved a great progress. But compared with the developed nations in the world, China is still in its infantry stage, and needs to learn from the western developed countries’ experiences in this field. This paper makes a comparative analysis of the differences between China and UK in postgraduate professional degree education. It finds that there are significant differences between the two countries in the aspects of programme setting, schooling duration, admissions, curriculum design, teaching delivery, quality control system, etc. The findings imply that China should try to give more authority to universities in programme setting and admissions, and Chinese universities should innovate ways of teaching delivery and systems of quality control.

The Ideal

Background: Tympanoplasty involves reconstitution of the tympano-ossicular system with commonly. fascia of the temporalis muscle, situated in its proximity. The fascia is grafted on the residual tympanic membrane by placing it either over it or below it, after creating a raw surface. The former is the overlay and latter, the underlay technique. In this study on restitution of the ear drum utilizing the overlay and underlay techniques, an exhaustive analysis of the two modalities has been done, taking into consideration various variables individually. The surgical outcome wrt to graft uptake and hearing gain has been compared in "depth" with extensive studies undertaken in India and abroad. The unbiased tabulated comparison of each aspect is unique and would guide future researchers to opt the ideal modality.Methods: Tympanoplasty was undertaken in chronic safe suppurative otitis media with the underlay and overlay techniques in a study group of 40 patients in this prospective study. The patients were randomly divided into equal groups for either procedure. Results: In the cohort of 40 subjects successful graft uptake was observed in 16 (80%) with overlay technique and 17 (85%) with underlay technique. Graft rejection was reported in 4 (20%) and 3 (15%) cases with overlay and underlay techniques respectively. Hearing improvement was 56.25% in 10-20 dB range in Overlay. Whereas, with underlay it was 47.05% in 10-2 dB.Conclusions: Overlay technique is ideal for anterior and central perforations while underlay for subtotal and posterior perforations. In terms of hearing improvement, the fibrosis during graft uptake makes the results of either technique unpredictable.
