Aim:Stiffness of the auricular cartilage is the main determining factor for the choice of operative technique of the prominent ear deformity. The aim of this study is to evaluate the stiffness of normal appearing ears objectively and quantitatively, compare the results with the operated prominent ear patients, and present prospective short-term dynamometric evaluation of the operated prominent ear patients.Patients and Methods:A total of 190 volunteers without ear deformities were recruited and 9 age groups were formed: group (5-9), group (10-14), group (15-19), group (20-24), group (25-29), group (30-34), group (35-39), group (40-49), and group (50+). Total 28 ears (14 patients) with otoplasty were included in the study as group (operated 5-9) and group (operated 10-14). In addition, 3 patients with prominent ear deformity were prospectively followed for dynamometric changes that occur with otoplasty operation. The auriculocephalic angle (ACA) was measured once and auricle to scalp distance was measured at 4 different standardized levels. Ear stiffness was measured on each ear individually at 4 different points over the antihelix using digital computer-aided dynamometry. Each ear was compared in terms of ACA, distance, and dynamometric values.Findings:Dynamometric values tend to increase with age, which increase and peak around 35 years of age and declines after 40 years of age. Measurements of the first 2 age groups were statistically different compared with the other groups. Postoperative dynamometric measurements (DNM) of group (operated 5-9) were similar with normative values of group (5-9) and postoperative satisfaction visual analogue scale (VAS) score was 92.8%. Postoperative DNM of group (operated 10-14) were higher compared with normative values of group (10-14) for each different measuring level and the postoperative satisfaction VAS score was 75.3. A total of 3 patients with prominent ears had lower dynamometric values preoperatively; these values approached closer to normative values of their age group postoperatively.Conclusions:Results show that auricular cartilage stiffens and malleability decreases with increased age. This stiffness peaks in the 35-39 age group and declines after 40 years of age. Dynamometric values increase, at all levels, suggesting increased cartilage stiffness is related to age. In the scope of these results, cartilage sparing techniques are more suitable for 5 to 14 years of age and cartilage-cutting techniques are more suitable for older patients.

Background: Pneumocephalus is a pathology characterized by air influx into the intracranial region. It may occur after head trauma and rarely after endoscopic sinus surgery. As the amount of air increases, this can cause neurological disorders with a mass effect and this condition is called tension pneumocephalus.

Objectives: The current study was designed to investigate the ototoxic effect of topical cefepime solution on the outer cell function of cochlea by measuring distortion product otoacoustic emission (DPOAE) amplitudes.

In the present experimental study, we sought to monitor distortion product otoacoustic emissions (DPOAEs) as an indicator of cochlear function, after sudden, total, and irreversible interruption of cochlear blood flow, to provide information on the time course of cochlear response to ischemia. Twenty rats with normal hearing function were included. Complete and abrupt ischemia was provided by decapitation. DPOAEs at 3–8 kHz frequencies were recorded at baseline and exactly every consecutive minute after decapitation, until emissions in all frequencies disappeared completely. Mean DPOAE values decreased significantly and progressively after decapitation for all frequencies. The mean duration of emissions was 8.20 ± 1.96 min (minimum 3 min, maximum 11 min). The longest durations of DPOAEs were observed with 4 and 5 kHz frequencies, and 3 and 6 kHz had the shortest durations. The outer hair cells exposed to acute ischemia seem to exhibit a rapid functional loss; thus, cautious handling of the cochlear vasculature and surrounding structures is necessary in surgical interventions. Additionally, our results provide some idea of the normal tolerance range of the cochlea to ischemia, which could be useful for future studies

Sudden sensorineural hearing loss can occur after both otolaryngological and non otolaryngological procedures. Sudden sensorineural hearing loss (SNHL) is a well-recognized phenomenon that is attributed to a variety of etiologies. After cardiopulmonary bypass surgery has been well reported. But this report adds to the literature additional case of sudden permanent bilateral SNHL after acute non-otology, non-cardiopulmonary, non-spine surgery. Possible etiologic factors and the management of sensorineural hearing loss following anesthesia are discussed.
