A Prospective Study

Introduction- The Eustachian tube provides an anatomic communication between the middle ear and nasopharynx, and maintains pressure equality across the tympanic membrane. Objective- To see the effect of anterior nasal packing on Otological symptoms, middle ear pressure and hearing Materials and method- This prospective study was carried out during period of September 2018 till August 2019. 100 ears were taken in the study. Middle ear pressure and hearing threshold were evaluated by Tympanometry and Audiometry respectively. Results- Postoperatively two days after anterior nasal packing, there was increase in no. of patient ears with ear fullness, ear ache, tinnitus, hearing threshold and abnormal negative middle ear pressure. After removal of nasal packing up to twelve weeks, improvement in middle ear pressure and hearing threshold was seen. Conclusion- Anterior nasal packing causes decrease in middle ear pressure and increase in hearing threshold. Key words- Eustachian tube, Middle ear pressure, Hearing threshold

Objectives To determine the incidence of possible obstacles and patients’ characteristics when performing endovenous laser treatment (EVLT) and suggestions to improve the ability to overcome them. Method A prospective study with 215 limbs treated with EVLT. A sequence of maneuvers was performed to move the fiber forward when difficulty was found and if unsuccessful another entry site was punctured. Results In 29 of 215 (13.48%) limbs, resistance was encountered while navigating the fiber; 16 (55.17%) solved with lower limb extension; 13 (44.82%) needed ultrasound guided maneuvers; five (17.24%) needed a saline flush and in three patients (10.34%) another entry site was necessary. In 214 of 215 cases (99.53%), ablation was accomplished and no complications were observed. Conclusions Both obstruction and higher patients' BMI are the main obstacles during endovenous laser ablation and usually needs additional maneuvers to accomplish the procedure in our study and the use of tricks to overcome these issues is feasible.

A Prospective Study

This is a prospective study that looks into the prevalence of chorda tympani nerve (CTN) injury and related symptoms following varying degrees of trauma to the nerve during three common types of middle-ear operation: myringoplasty, tympanotomy and mastoidectomy. The number of patients with CTN-related symptoms varied widely between the three groups. Increased occurrence of the nerve related symptoms and a prolonged recovery time were observed in the tympanotomy group. Stretching of the nerve produced more symptomatic cases than cutting it in the myringoplasty and mastoidectomy groups. Recovery was complete in 92 per cent of the symptomatic patients by 12 months. It is important to inform patients about the possibility of CTN injury during middle-ear operations, and it should also be emphasized that symptoms related to CTN injury can occur irrespective of the type of damage to the nerve.

A Prospective Study

Introduction Although temporalis fascia is the commonly used graft material for tympanoplasty, cartilage has become the material of choice in cases with eustachian tube dysfunction, bilateral disease, total or anterior perforation of tympanic membrane, tympanosclerosis etc. Cartilage slices < 0.5 mm thick are similar to the tympanic membrane in their acoustic properties. The present study is aimed to describe stitch-less type 1 tympanoplasty with sliced tragal cartilage-perichondrium and evaluate anatomical, audiological and cosmetic outcomes. Materials and Methods A prospective study was conducted from March 2014 to August 2016, in ENT department of a Government Medical College and Hospital, West Bengal, India. Primary tympanoplasty cases irrespective of age, size and site of perforation, laterality and eustachian tube function were included in the study. History of previous tympanoplasty or mastoid surgery and cases requiring ossicular reconstruction or mastoidectomy were excluded from the study. Sliced tragal cartilage-perichondrium graft of 0.2 mm thickness was placed in underlay fashion through trans-canal or end-aural route. Results Among 95 cases 38 were male, 57 were female with age range between 7 to 68 years. Average operative time was 30 minutes. Graft take was successful in 97.89% of cases. Average Air Bone Gap 12 months after operation was 13.03dB. Conclusion Sliced cartilage-perichondrium graft gives good balance between sufficient stability and adequate acoustic sensitivity. Moreover, no stitch technique reduces operative time and increases cosmesis.

A Prospective Study

We undertook a prospective study to determine the safety and effectiveness of the direct administration of a steroid to the eustachian tube via the Silverstein MicroWick in 11 patients with chronic eustachian tube dysfunction, including two who had Samter's triad. All patients had previously been treated with medical therapy and surgical middle ear ventilation without resolution. The MicroWick was placed directly in the eustachian tube orifice through a pressure-equalization tube. Patients received 3 drops of dexamethasone 4 mg/ml three times a day. The drops were discontinued after 4 weeks, and the MicroWick and ventilation tube were removed after 3 months. At study's end, eight patients (72.7%) reported subjective improvement in terms of a reduction in aural pressure and fullness. Audiometric testing demonstrated a 55% reduction in the mean air-bone gap and a 3% increase in the mean speech discrimination score. Bone pure-tone averages remained stable. Tympanometry showed that five patients (45.5%) converted from type B or C tympanograms to type A. Four patients (36.4%) had persistent perforations. Both patients with Samter's triad improved with therapy. These preliminary results suggest that direct dexamethasone administration to the eustachian tube is safe and effective for the treatment of chronic eustachian tube dysfunction. Long-term studies to confirm these findings are under way.
