Is there a relationship between middle concha bullosa and ethmoid roof asymmetry? / Existe uma relação entre a concha média bolhosa e a assimetria do teto etmoidal?

Abstract Introduction The middle turbinate and ethmoid roof are intranasal structures and may have many anatomical variations. These structures, which serve as anatomical markers during functional sinus surgery, are important for preventing complications and performing a proper surgery. Knowledge of anatomical variations will increase surgical success and reduce complications. Objective We aimed to investigate the presence of asymmetry in the ethmoidal roof and anatomical variation in patients with and without concha bullosa. Methods In this study, the files of patients who underwent paranasal computed tomography between 2012 and 2018 were analyzed retrospectively. The patients were divided into two groups, as patients with and without concha bullosa. Differences between the two groups in terms of age, gender, septum deviation, ethmoid artery dehiscence, ethmoid roof asymmetry were examined. Results The 369 patients included in our study were divided into two groups; those with concha bullosa and those without concha bullosa. The mean age of the patients with concha bullosa was 36.1 ± 13.4 (min-max: 12-74) and the mean age of patients without concha bullosa was 37.5 ± 14.3 (min-max: 10-81). The ethmoid roof depths were compared between the two groups and a significant difference was observed (p < 0.001). The ethmoid roof depth was higher in the group with concha bullosa (p < 0.001). Conclusion The results of our study indicate that the ethmoidal roof tends to be higher in patients with middle concha bullosa.

Resumo Introdução A concha média e o teto etmoidal são estruturas intranasais e podem apresentar muitas variações anatômicas. Essas estruturas, usadas como marcadores anatômicos durante a cirurgia sinusal funcional, são importantes para evitar complicações e para a feitura adequada da cirurgia. O conhecimento das variações anatômicas aumenta o sucesso cirúrgico e reduz as complicações. Objetivo Investigar a presença de assimetria no teto etmoidal e variações anatômicas em pacientes com e sem concha bolhosa. Método Os prontuários dos pacientes submetidos à tomografia computadorizada de seios paranasais entre 2012 e 2018 foram analisados retrospectivamente. Os pacientes foram divididos em dois grupos, pacientes com e sem concha bolhosa. As diferenças entre os dois grupos em termos de idade, sexo, desvio do septo, deiscência da artéria etmoidal e assimetria do teto etmoidal foram avaliadas. Resultados Os 369 pacientes incluídos em nosso estudo foram divididos em dois grupos: com concha bolhosa e sem concha bolhosa. A média de idade dos pacientes com concha bolhosa foi de 36,1 ± 13,4 (mín-máx: 12-74 anos) e a média de idade dos pacientes sem concha bolhosa foi de 37,5 ± 14,3 (mín-máx: 10-81 anos). As profundidades do teto etmoidal foram comparadas entre os dois grupos, observou-se diferença significante (p < 0,001). Observou-se que a profundidade do teto etmoidal foi maior no grupo com concha bolhosa (p < 0,001). Conclusão O resultado do nosso estudo indica que pacientes com concha média bolhosa tendem a apresentar uma maior profundidade do teto etmoidal.

Is there a relationship between middle concha bullosa and ethmoid roof asymmetry?

INTRODUCTION: The middle turbinate and ethmoid roof are intranasal structures and may have many anatomical variations. These structures, which serve as anatomical markers during functional sinus surgery, are important for preventing complications and performing a proper surgery. Knowledge of anatomical variations will increase surgical success and reduce complications. OBJECTIVE: We aimed to investigate the presence of asymmetry in the ethmoidal roof and anatomical variation in patients with and without concha bullosa. METHODS: In this study, the files of patients who underwent paranasal computed tomography between 2012 and 2018 were analyzed retrospectively. The patients were divided into two groups, as patients with and without concha bullosa. Differences between the two groups in terms of age, gender, septum deviation, ethmoid artery dehiscence, ethmoid roof asymmetry were examined. RESULTS: The 369 patients included in our study were divided into two groups; those with concha bullosa and those without concha bullosa. The mean age of the patients with concha bullosa was 36.1 ±â€¯13.4 (min-max: 12-74) and the mean age of patients without concha bullosa was 37.5 ±â€¯14.3 (min-max: 10-81). The ethmoid roof depths were compared between the two groups and a significant difference was observed (p < 0.001). The ethmoid roof depth was higher in the group with concha bullosa (p < 0.001). CONCLUSION: The results of our study indicate that the ethmoidal roof tends to be higher in patients with middle concha bullosa.

The effect of different types of music on patients' preoperative anxiety: A randomized controlled trial.

OBJECTIVE: The purpose of this study was to determine effect of three different types of music on patients' preoperative anxiety. METHOD: This randomized controlled trial included 180 patients who were randomly divided into four groups. While the control group didn't listen to music, the experimental groups respectively listened to natural sounds, Classical Turkish or Western Music for 30 min. The State Anxiety Inventory (STAI-S), systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR) and cortisol levels were checked. FINDINGS: The post-music STAI-S, SBP, DBP, HR and cortisol levels of the patients in music groups were significantly lower than pre-music time. All types of music decreased STAI-S, SBP, and cortisol levels; additionally natural sounds reduced DBP; Classical Turkish Music also decreased DBP, and HR. CONCLUSIONS: All types of music had an effect on reducing patients' preoperative anxiety, and listening to Classical Turkish Music was particularly the most effective one.

The effect of coenzyme Q10 on the regeneration of crushed facial nerve.

OBJECTIVE: The aim of this study is to show the possible positive effect of coenzyme Q10 (Co Q10) on regenerating in facial palsy. MATERIALS AND METHODS: Sixteen female Sprague-Dawley albino rats were randomly divided into 2 groups as Co Q10 and control groups. Group Q10 (n = 8) received Co Q10 of 10 mg/kg/d intraperitoneally for 30 days, and group C (n = 8) received saline solution of 1 mL/d intraperitoneally once daily for 30 days. The right facial nerve stimulation thresholds were determined before crush, immediately after crush, and after 1 month.After determination of the thresholds, the crushed part of the facial nerve was then excised. All specimens were examined by a pathologist using a light microscope. RESULTS: No statistically significant difference in stimulation threshold was found between the Co Q10 and saline groups after crushing (P = 0.645). After 1 month of treatment, stimulation thresholds were significantly lower in both the Co Q10 and saline groups (Ps = 0.028 and 0.016). However, the Co Q10 group showed greater improvement than the saline group (P = 0.050).After 1 month of treatment, neither the Co Q10 group nor the saline group had reached the precrushing amplitude levels (Ps = 0.027 and 0.011).Significant differences were found in vascular congestion, macrovacuolization, and myelin thickness between the Co Q10 and control groups by light microscopy (P < 0.05). CONCLUSIONS: Although many treatment methods have been tried to accelerate facial nerve regeneration after trauma, a definitive method has not been found yet. Co Q for the treatment of acute facial paralysis is promising on both physiologic assessments and pathologic evaluation.

Is it necessary to do temporal bone computed tomography of the internal auditory canal in tinnitus with normal hearing?

OBJECTIVE: To investigate the compression of the vestibulocochlear nerve in the etiology of the tinnitus in the normal hearing ears with temporal bone computed tomography scans. METHODS: A prospective nonrandomized study of 30 bilateral tinnitus and 30 normal hearing patients enrolled in this study. RESULTS: A total of 60 patients (ages ranged from 16 to 87) were included. The tinnitus group comprised 11 males and 19 females (mean age 49,50 ± 12,008) and the control group comprised 6 males and 24 females (mean age 39,47 ± 12,544). Regarding the right and left internal acoustic canals measurements (inlet, midcanal, and outlet canal lengths), there were no significant differences between the measurements of the control and tinnitus groups (P > 0.005). There was no narrowness in the internal acoustic canal of the tinnitus group compared with the control group. High-frequency audiometric measurements of the right and left ears tinnitus group at 8000, 9000, 10000, 11200, 12500, 14000, 16000, and 18000 Hz frequencies were significantly lower than the control group thresholds (P < 0.05). There was high-frequency hearing loss in the tinnitus group. CONCLUSION: There were no anatomical differences in the etiology of tinnitus rather than physiological degeneration in the nerves.
