Ear nose throat-related symptoms with a focus on loss of smell and/or taste in COVID-19 patients.

PURPOSE: To determine the frequency and severity of general and ear nose throat (ENT)- related symptoms, especially smell and/or loss of sense of taste (STL) in COVID-19 disease, as well as to investigate the recovery process of STL. MATERIALS AND METHODS: Patients with a positive COVID-19 diagnosis were given a questionnaire consisting of general questions (age, sex, date of symptoms, smoking history, concomitant diseases), questions about the most obvious symptom at presentation (one option only), the severity and frequency of symptoms (general and ENT), and STL (recovery time and degree of recovery). RESULTS: The study population consisted of 172 patients, 18-65 years old (mean age, 37.8 ± 12.5 years; 51.2% female; 76.2% nonsmokers). Cough (n = 30, 17.4%) and loss of sense of smell (n = 18, 10.4%) were the most obvious general and ENT symptoms, respectively. Eighty-eight patients (51.2%) reported loss of sense of smell, and 81 patients (47.1%) reported loss of sense of taste. The mean recovery times for loss of sense of smell and loss of sense of taste were 8.02 ± 6.41 and 8.20 ± 7.07 days, respectively. The loss of sense of smell and loss of sense of taste were the unique symptoms in four (4.54%) and one (1.23%) patients, respectively. CONCLUSION: STL is a common symptom in COVID-19 and may be the first and/or only symptom of this disease. In patients presenting with STL complaints, surveillance for possible COVID-19 disease and screening tests will facilitate the struggle against the disease.

A novel myringoplasty technique: the placement of a complementary graft descending from the scutum to support an anterosuperior perforation.

We describe a novel myringoplasty procedure. We placed a separated fascia graft descending from the scutum, combined with underlay myringoplasty, to support an anterosuperior perforation. We reviewed data from patients who underwent myringoplasty procedures to treat perforations extending into the anterosuperior quadrant of the pars tensa from October 2012 to June 2014. A total of 42 patients who were followed for a minimum of 1 year were enrolled. The same technique was used in all operations. The tympanomeatal flap was elevated from the neck of malleus up to the tip of the lateral process of malleus. The anterior mallear fold was incised to create an opening running from the neck of the malleus to the anterior tympanic spine. A separate temporal fascia graft (complementary graft) was next inserted through the opening and pushed down into the protympanum. The upper part of the fascia graft was placed over the superior bony wall of the canal. Underlay myringoplasty was then performed. The inferior part of the fascia graft was next spread out to cover the lateral surface of the underlying graft. We measured graft take rate and preoperative and postoperative hearing parameters. The graft success rate was 97.7 % (41/42 patients). The preoperative air-bone gap was 22.56 ± 18.12 dB, and the postoperative air-bone gap was 8.4 ± 10.05 dB. This difference was statistically significant (P < 0.001). We believe that this myringoplasty technique is a safe, suitable, and effective for cases with tympanic membrane perforations extending into the anterosuperior quadrant of the pars tensa.

Clinical characteristics and follow-up of patients with external ear canal cholesteatoma treated conservatively.

We conducted a retrospective study to evaluate the clinical properties and follow-up of patients with external ear canal cholesteatoma (EECC) who were treated conservatively. Our study group was made up of 15 patients-6 men and 9 women, aged 21 to 82 years (mean: 48). In addition to demographic data, we compiled information on presenting signs and symptoms, the location of the lesion, treatment, and follow-up. All EECCs occurred spontaneously, and all were limited to the temporal bone. Lesions were left-sided in 7 patients, right-sided in 7, and bilateral in 1. For purposes of defining the location of the lesions, the ear canal was divided into four quadrants: anterior, posterior, superior, and inferior. Temporal bone computed tomography (CT) and otomicroscopic evaluation revealed that 7 of the 16 lesions (44%) were located in the anterior and inferior quadrants, 6 (38%) in the inferior quadrant only, 2 (13%) in the anterior, inferior, and posterior quadrants, and 1 (6%) in the anterior quadrant only. Otorrhea was present in 7 of the 15 patients (47%), otalgia in 6 (40%), itching in 4 (27%), fullness in 2 (13%), and occlusion in 1 (7%); 3 patients (20%) were asymptomatic. All patients were treated with local debridement and aspiration under otomicroscopy, and they were followed up with repeat aspirations approximately every 10 weeks under microscopy. The duration of follow-up ranged from 6 to 75 months (mean: 41). At study's end, cholesteatoma had not progressed in any patient during follow-up, indicating that repeat aspirations and regular follow-up of limited EECC prevent recurrence of signs and symptoms and progression of the disease.

The effect of stapes fixation on hearing results in tympanosclerosis treated by mobilization.

We aimed to investigate the effect of stapes fixation on hearing results in patients who underwent mobilization surgery due to tympanosclerosis (TS). Seventy-nine patients were retrospectively analyzed and divided into two groups. Forty-four (55.7%) patients with mobile stapes were classified as group 1, and 35 (44.3%) patients with fixed stapes were classified as group 2. Improvement of the air-bone gap (ABG) to become less than 20 dB and the pure-tone average (PTA) by at least 10 dB postoperatively were accepted as success criteria. The PTA and ABG levels were significantly improved in both groups. The pre- and post-operative PTAs were 46.57 ± 15.55 and 25.84 ± 15.47 dB, respectively, in group 1 (p = 0.001). The pre- and post-operative PTAs were 55.64 ± 12.69 and 36.20 ± 14.47 dB, respectively, in group 2 (p = 0.001). The pre- and post-operative ABG levels were 35.36 ± 10.53 and 16.91 ± 8.54 dB, respectively, in group 1 (p = 0.001). The pre- and post-operative ABG levels were 41.68 ± 8.78 and 22.20 ± 10.03 dB, respectively, in group 2 (p = 0.001). A gain ≥10-dB in the PTA in groups 1 and 2 was found in 34 (77.2 %) and 23 (65.7%) patients, respectively, and the difference between the groups was not significant (p = 0.684). The post-operative AGB in groups 1 and 2 was less than 20 dB in 32 (72.7%) and 21 (60%) patients, respectively, and the difference between the groups was not significant (p = 0.733). No significant negative effect of stapes fixation on post-operative hearing results in TS was detected. Successful results can be obtained with a mobilization procedure, even if the stapes is fixed.

Surgery of isolated malleus fixation due to tympanosclerosis.

The aim of the present study was to describe our surgical approach for isolated malleus fixation in patients with tympanosclerosis and to analyze the postoperative results. A total of 30 patients presented with isolated malleus fixation were operated. The fixation was reached via canalplasty. Fixated areas were cleaned without damaging the ossicle. Pre- and postoperative audiometric results were evaluated for each patient. Improvement of the pure-tone average (PTA) by at least 10 dB and an air-bone gap (ABG) of less than 20 dB after 12 months of follow-up was accepted to indicate success. The recovery of the postoperative PTA and ABG measurements was significant. Pre- and postoperative PTA was 48.00 ± 11.86 and 24.90 ± 12.45 dB, respectively (p < 0.001). According to PTA measurements, 40-50 dB recovery was achieved in four (13.3 %) patients, 31-40 dB in six (20 %) patients, 21-30 dB in ten (33.3 %) patients, and 11-20 dB in five (16.6 %) patients, with a total success rate of 25/30 (83.2 %). Pre- and postoperative ABG levels were 38.95 ± 9.92 and 16.10 ± 7.79 dB (p < 0.001), respectively. The ABG level was between 0 and 10 dB for 8 (26.6 %) patients, and 11-20 dB for 16 (53.3 %), with a total success rate of 24/30 (80 %). In cases of isolated malleus fixation with tympanosclerosis, performing a canalplasty to clean the sclerotic plaques without damaging the normal anatomy of the ossicle system using a diamond burr is a safe surgical option that provides significant recovery in hearing levels.

Does the use of radiofrequency myringotomy for insertion of a ventilation tube reduce the incidence of myringosclerosis?

The aim of the present study was to determine the rate of myringosclerosis after radiofrequency (RF) myringotomy and ventilation tube (VT) insertion and compare it with that after the incisional myringotomy and VT insertion. Thirty children (60 ears), 2-16 years old (mean age 7.06 ± 2.77 years) who were planned to undergo surgical intervention for bilateral otitis media with effusion (OME), were included in this study. The children were treated by RF myringotomy of the right ear, incisional myringotomy of the left ear, and insertion of VTs into both ears. Both ears were examined intraoperatively for bleeding, and patients were evaluated for myringosclerosis formation with otomicroscopy at the end of the ninth month. Myringosclerosis was observed in 22 of the 60 ears. The overall incidence was 36.6 %. Fifteen (50 %) left ears showed myringosclerosis by otomicroscopy, and seven (23.3 %) right ears showed myringosclerosis. The rate of myringosclerosis of the right ear was significantly lower than that of the left ear (p < 0.05). In addition, intraoperative tympanic membrane bleeding was observed in 24 (40 %) of the 60 ears: 21 (70 %) left ears and three (10 %) right ears were perforated by RF. The tympanic membrane bleeding rate of the right ear was significantly lower than that of the left ear (p < 0.01). The present study is the first to determine the myringosclerosis rate after RF myringotomy and VT insertion. Our results indicate that VT insertion with RF myringotomy decreased the incidence of myringosclerosis.

Extensive tympanic membrane cholesteatoma with marginal perforation: an unusual case.

The migration of squamous epithelium of external ear through a tympanic membrane perforation into the middle ear forms a cholesteatoma. But it is extremely a rare condition to observe extensive cholesteatoma on the medial surface of tympanic membrane with perforation. This condition is termed tympanic membrane cholesteatoma (TMC). We herein present an exceptional case of extensive TMC with marginal perforation.

Levels of reactive oxygen species in rat tympanic membranes after incisional versus radiofrequency myringotomy.

OBJECTIVE: A close relationship between reactive oxygen species (ROS) and myringosclerosis, which is a common complication of myringotomy, was recently reported. The objective of this study was to measure ROS levels directly in rat tympanic membranes using luminol-aided chemiluminescence (CL) in order to compare the levels of ROS after incisional and radiofrequency (RF) myringotomy. METHODS: Fifteen Sprague-Dawley rats were separated into three groups of five animals each. Bilateral myringotomies were made using an appropriate myringotomy lancet in Group 1 and RF in Group 2. Group 3 served as the control group with no myringotomy. Twenty-four hours after the procedure, all tympanic membranes were inspected with an otomicroscope and then excised for the measurement of ROS using luminol-aided CL. RESULTS: The mean ROS level in Group 1 was significantly higher than that in Groups 2 and 3 (p<0.05 for both). The difference in mean ROS level between Groups 2 and 3 was not significant (p>0.05). Otomicroscopy revealed increased vascularity and vessel dilation in all tympanic membranes that underwent myringotomy. Vascular dilation was observed in the annular region in the vessels that passed along the long arm of the malleus, in addition to the vessels feeding the anterior and posterior tympanomalleolar folds. CONCLUSIONS: Although the relationship between ROS and the development of myringosclerosis after myringotomy has been demonstrated, the present study is the first to compare incisional and RF myringotomy based on the measurement of ROS levels. Our results indicate that the increase in ROS due to myringotomy was greater following incisional myringotomy than RF myringotomy.
