Vestibular function assessment in Idiopathic sudden sensorineural hearing loss: a prospective study.

PURPOSE: Idiopathic sudden sensorineural hearing loss (ISSHL) can cause acute damage not only to the auditory function, but also to the vestibular function in addition to damage to the hearing function. The aim of this study was to perform vestibular assessment using caloric test and video head impulse test in patients with idiopathic sudden sensorineural hearing loss. In addition, to evaluate the relationship of dizziness with vestibular tests and post-treatment responses of vestibular tests. METHODS: This is an observational, longitudinal and prospective study, including patients diagnosed with idiopathic sudden sensorineural hearing. Patients were divided into two groups according to the presence of vestibular complaints at presentation: Group 1: Patients with vestibular complaints, Group 2: Patients without vestibular complaints. All subjects underwent pure tone audiometry (PTA) testing, cold caloric test and video head impulse test (vHIT) during their admission and on the 10th day, 3rd month, and 1st year of their follow-up outpatient clinic controls. A unilateral weakness (UW) in the caloric test response was quantified according to the Jongkees formula. RESULTS: A positive and significant relationship was found between the degree of hearing loss according to the ASHA criteria pre-treatment and the level of improvement created according to Siegel criteria at the 10th day, 3rd month, 1st year after treatment (respectively p = 0.001, p = 0.001, p < 0.001). When both short-term and long-term results were evaluated after treatment, a positive improvement in the degree of hearing loss was observed. A statistically significant difference was observed between Groups 1 and 2 when the pre-treatment, at 10 days, 3 months and 1 year after treatment the caloric test UW value was compared (respectively p = 0.020, p = 0.004, p = 0.004, p = 0.004). A statistically significant difference was observed between Groups 1 and 2 when the pre-treatment, at 10 days, 3 months and 1 year after treatment vHIT lateral canal VOR value was compared (respectively p = 0.000, p = 0.001, p = 0.000, p = 0.004). When both short-term and long-term results were evaluated after treatment, a positive improvement was observed in both caloric test results and lateral vHIT VOR values. Pre-treatment, post-treatment 10th day, 3rd month, 1st year vHIT anterior and posterior canal VOR values were found to be VOR˃0.8 in all patients. No difference was observed in anterior and posterior canal VOR values. CONCLUSION: Vertigo in patients with ISSHL "as objectively confirmed through caloric testing and vHIT" can be considered a sign of severe cochlear damage. Our study demonstrated a significantly increased risk of vestibular affect in patients with ISSHL, especially in the presence of vertigo. Thus, we conclude that the focus in ISSHL should not only be on the cochlea but also on the vestibular system.

Outcome of In Situ Septoplasty and Extracorporeal Subtotal Septal Reconstruction in Crooked Noses: A Randomized Self-Controlled Study.

IMPORTANCE: Severe dorsal deviations in crooked noses are treated by either in situ septoplasty with asymmetric spreader grafts (ISS) or extracorporeal subtotal septal reconstruction (ECS). To our knowledge, except one retrospective study, there is no other that compares the objective and subjective results of these two treatment modalities. OBJECTIVE: The aim of this study was to compare the aesthetic and functional outcomes of ECS and ISS in crooked noses. DESIGN, SETTING AND PARTICIPANTS: This study was carried out on 40 patients (ISS in 20 patients and ECS in 20 patients) who underwent external rhinoplasty surgery due to crooked noses between May 2014 and January 2016. While performing rhinoplasty on the patients, the decision of whether to use the ECS or ISS technique was randomized in a sequential fashion. MAIN OUTCOMES AND MEASURES: Surgical outcomes were assessed and compared using the anthropometric measurement of photographs with Rhinobase software. Subjective assessments of nasal obstruction and aesthetic satisfaction were evaluated with a visual analog scale. RESULTS: There was a significant difference between rhinion deviation angle, supratip deviation angle (SDA) and tip deviation angle pre- and postoperatively in the ECS group, whereas in the ISS group, except SDA, all other postoperative angles were significantly improved from preoperative values (p = 0.218). The nasal tip projection in the ECS and ISS groups was 29.48, 31.5 preoperatively and 29.78, 31.26 postoperatively. The mean postoperative nasal tip projection value (p > 0.005) did not change significantly compared to the preoperative value in both groups. The mean postoperative value of nasolabial (p = 0.226) angle did not change significantly compared to the mean preoperative one in the ECS group. However, in the ISS group, the mean postoperative value of nasolabial (p = 0.001) angle significantly improved compared to the mean preoperative value. There was significant improvement in both groups, while improvements in both functional and aesthetic outcomes were much higher in the extracorporeal group. None of the patients had postoperative nasal obstruction that required revision surgery. One patient underwent revision rhinoplasty due to an irregularity on the nasal dorsum in the ECS group. CONCLUSIONS AND RELEVANCE: This is the first study that compares subjective and objective aesthetic and functional outcomes of crooked nose surgery according to two common septoplasty techniques in a randomized self-controlled fashion. This study was effective in both objectively and subjectively comparing the functional and aesthetic aspect of the patients submitted to two common different techniques of treatment of nasal deviations in crooked nose patients.
