Study of Outcome of Tympanoplasties in Relation to Size and Site of Tympanic Membrane Perforation

There are not many studies on the effect of the site and size of the perforation on the hearing loss. This study is set to investigate the relationship between the size and site of perforation and hearing loss. This study was carried out between September 2011 to September 2013, at a tertiary care centre during which 100 cases of chronic otitis media tubotympanic type having central perforation were selected. All patients underwent, tympanoplasty using temporalis fascia/cartilage graft, underlay technique with or without simple mastoidectomy/modified radical mastoidectomy and followed up for 3 months and evaluated for graft uptake and hearing improvement with respect to size and site of TM perforation. To measure the size of perforation intra-operatively, thin transparency sheet was used, on which a graph paper of 1 × 1 mm² size was printed. Significant relationship was observed between size and site of tympanic membrane perforation with hearing loss. Perforations which were involving all four quadrants (AS + AI + PS + PI) are having maximum residual perforations after the surgery. In relation with size, subtotal perforation were having more residual perforations postoperatively, followed by medium sized perforations. An inherent relationship noted between ossicular involvement and hearing loss, maximum average hearing loss was observed in those cases, where all three ossicles (malleus, incus & stapes) were involved, also more hearing loss was noted in posterior perforations.     

Golden 60 minutes of newborn’s life: Part 1: Preterm neonate

“Golden 60?minutes “or “Golden Hour” is defined as the first hour of the newborn after birth. This hour includes resuscitation care, transport to nursery from place of birth and course in nursery. The concept of “Golden hour” includes evidence based interventions that are done in the first 60?min of postnatal life for the better long term outcome of the preterm newborn especially extreme premature, extreme low birth weight and very low birth weight. The evidence shows that the concept of “Golden 60?minutes” leads to reduction in neonatal complications like hypothermia, hypoglycemia, intraventricular hemorrhage, chronic lung disease and retinopathy of prematurity. In this review, we have covered various interventions included in “Golden hour” for preterm newborn namely delayed cord clamping, prevention of hypothermia, respiratory and cardiovascular system support, prevention of sepsis, nutritional support and communication with family.     

TMJ Vibrations in Asymptomatic Patients Using Old and New Complete Dentures

Purpose: The aim of this study was to assess the presence of temporomandibular joint (TMJ) noises in subjects with severe bone resorption, who have worn the same complete dentures for over 10 years, and 5 months after treatment with increments of acrylic resin on the occlusal surface after having new dentures in place. Methods: After applying the research diagnostic criteria (RDC)/temporomandibular disorder (TMD) questionnaire, 20 asymptomatic subjects were assessed before and 5 months after the new dentures were put in place. Joint vibrations were assessed by the Sono Pak program by selecting the vibrations that occurred during the opening and closing cycle. Results: The means of the results revealed a nonnormal distribution and were submitted to Kruskal‐Wallis statistical analysis (p < 0.05). The vibration means were of low intensity (≤9.96 Hz). After rehabilitation, there was a reduction in the vibrations (≤5.2 Hz) statistically significant only at the end of mouth opening with the old dentures when compared with the other cycles. Conclusion: The intensity and number of occurrences of joint vibrations were reduced after 5 months of wearing new dentures.
