Background: Surgical correction of the bony vault is challenging part of rhinoplasty surgery. Over resection and dorsal irregularities are common complications of manual osteotomy that can occur even in the hands of practiced surgeons. Power-assisted instrumentation now offers a useful alternative for precise and controlled reduction of the bony vault. Patients and Methods: 40 patients were included in this study, Patients were divided into two groups: Group A (20 patients) was operated using conventional cold instruments. Group B (20 patients) was operated upon using power instruments. Results: On comparison between both groups regarding VAS cosmetic results, we found that the results were not statistically significant (P value = 0.3). Although that the postoperative VAS-Cosmetic results of good and excellent improvement in group (A) was 65% compared to 75% in group (B). Also on comparison between both groups regarding the assessment of preoperative and postoperative photography, we found that the results were not statistically significant (P value = 0.4). Although that the patients showed good and excellent improvement were 60% in group (A) compared to 70% in group (B). Conclusion: Power-assisted instrumentation system is minimally invasive and sharply decrease the incidence of complications associated with manual procedures.
背景:骨拱顶的手术矫正是鼻整形手术中具有挑战性的一部分。过度切除和背侧不规则是手工截骨术的常见并发症,即使在熟练的外科医生手中也可能发生。现在,动力辅助器械为精确和可控的骨拱顶复位提供了有用的替代方法。患者与方法:本研究共纳入40例患者,患者分为两组:A组(20例)采用常规冷器械手术。B组(20例)采用动力器械手术。结果:两组VAS美容效果比较,差异无统计学意义(P值= 0.3)。虽然A组术后VAS-Cosmetic的良、优改善率为65%,B组为75%。同样在两组术前、术后摄影评估的比较中,我们发现结果无统计学意义(P值= 0.4)。虽然A组患者的良好和极好改善率为60%,而B组为70%。结论:动力辅助器械系统具有微创性,可显著降低人工手术相关并发症的发生率。

Background: Central auditory processing disorders (CAPDs) tend to affect an individual’s ability to understand speech, especially in difficult listening conditions. Objective: To study speech-in-noise (SIN) ability in cases of central auditory processing disorders (CAPDs) subjectively by Arabic Hearing in Noise Test (A-HINT) and objectively by Speech-evoked auditory brainstem response (S-ABR) with ipsilateral noise. Patients and Methods: Subjects included in this study will be divided into 2 groups: a control group which included 30 normal hearing subjects (17 males and 13 females). Their age ranged from 6 to 17 years. All subjects had normal developmental milestones and normal speech development. The Study group included 30 normal hearing subjects (18 males and 12 females). Their age ranged from 7 to 16 years. These subjects had central auditory processing disorders (CAPDs) diagnosed by central auditory screening tests. Both groups were tested using Arabic HINT and Speech-evoked auditory brainstem response (S-ABR) with ipsilateral noise. Results: Comparison between control and study groups as regards the Arabic HINT revealed statistically significant differences in noise conditions. Using S-ABR significant difference was found in onset and offset response waves latency in noise conditions also. Conclusion: Patients with CAPDs have speech in noise ability affection proved by affected HINT in noise conditions and by delayed SABR with ipsilateral noise latencies in onsetoffset responses.
背景:中枢性听觉处理障碍(CAPDs)倾向于影响个体理解言语的能力,特别是在听力困难的情况下。目的:主观上通过阿拉伯语噪声听力测试(A-HINT)和客观上通过同侧噪声下的言语诱发听觉脑干反应(S-ABR)研究中枢性听觉加工障碍(CAPDs)患者的语音噪声能力。患者与方法:本研究将受试者分为两组:对照组:30名听力正常的受试者(男性17名,女性13名)。他们的年龄从6岁到17岁不等。所有受试者均具有正常的发育里程碑和正常的语言发育。研究组包括30名听力正常的受试者(男18名,女12名)。他们的年龄从7岁到16岁不等。这些受试者被诊断为中枢性听觉加工障碍(CAPDs)。两组均采用阿拉伯语提示和同侧噪声下的言语诱发听觉脑干反应(S-ABR)进行测试。结果:实验组与对照组在阿拉伯语提示音方面的差异有统计学意义。采用S-ABR方法,在噪声条件下,初始响应波和偏移响应波潜伏期也存在显著差异。结论:capd患者在噪声条件下有受影响的HINT,在起病反应中有伴同侧噪声潜伏期的延迟SABR,证明其在噪声条件下有言语能力的影响。

Background: The most common learning disability affecting academic performance is Dyslexia. Linguistic abilities like morphological awareness, semantic and syntactic abilities play a key role in reading development too. The paper aimed to study the extent and properties of morphological aspects and syntactic functioning in relation to reading skills in a group of Egyptian children having poor academic achievement as for designing suitable intervention plans for these children. Patients and Methods: Our study aimed to assess the extent and properties of morphological aspects and syntactic functioning in relation to reading skills in 40 Egyptian Arabic speaking children of the same socioeconomic state and age range from 6 years to 8 years with poor academic performance. The children divided into two groups were subjected to a protocol of assessment applied in Phoniatrics Unit Kasr Al aini Hospital, Arabic Dyslexia Assessment Test and language skills assessment by Receptive Expressive Arabic Language scale- REAL scale were applied. Results: All children with poor scholastic achievement were found to be at risk for developing dyslexia if not suffering from it. They suffered from below average level of performance in receptive, expressive and total language. All language parameters showed significant correlation with rapid naming. Below average morpho-syntactic abilities of children with poor scholastic achievement significantly correlated with tests of attainment (except for spelling) and diagnostic tests (except for bead threading). Conclusion: Our study supports that language disability underlies poor scholastic achievement.
背景:影响学习成绩的最常见的学习障碍是阅读障碍。形态意识、语义和句法能力等语言能力在阅读发展中也起着关键作用。本文旨在研究一组学习成绩差的埃及儿童在阅读技能方面的形态方面和句法功能的程度和性质,以便为这些儿童设计合适的干预计划。患者和方法:我们的研究旨在评估40名具有相同社会经济地位和年龄的6至8岁学习成绩较差的埃及阿拉伯语儿童与阅读技能相关的形态方面和句法功能的程度和性质。两组儿童采用Kasr Al aini医院语音科的评估方案,采用阿拉伯语阅读障碍评估测试和接受性表达阿拉伯语量表- REAL量表进行语言技能评估。结果:所有学习成绩差的儿童如果没有患上阅读障碍,都有患阅读障碍的风险。他们在接受、表达和整体语言方面的表现低于平均水平。所有语言参数均与快速命名有显著相关。学业成绩差的儿童的形态句法能力低于平均水平,与学业成就测试(拼写除外)和诊断测试(头部穿线除外)显著相关。结论:我们的研究支持语言障碍是学习成绩差的根本原因。

ABSTRACT Objectives: Hearing is a critical sense that affects the ability of persons especially children to communicate with others, share their thoughts and opinions, and participate in activities. In this descriptive cross-sectional study, school age children aged 6-12 years old in El-Mahalla El-Kubra district of Egypt were screened for hearing loss. Patients and Methods: Three hundred children were involved in this study from one rural and another urban primary school in El-Mahalla El-Kubra district of Egypt. All children were screened for hearing loss at their schools during the academic year 2017/2018. The positive cases were referred for basic audiological evaluation at El-Mahalla El-Kubra general hospital. All children were submitted to history taking through questionnaire, otoscopic examination, tympanometry and pure tone audiometry. Results: In this study, the prevalence of hearing loss was (9.2%) of the studied children. The most common type of hearing impairment was conductive hearing loss due to Eustachian tube dysfunction (4.7%) and secretory otitis media (3.3%). Conclusion: Recurrent ear infection is the commonest cause of hearing loss in children and hearing evaluation of school children is useful to avoid the impact of permanent hearing loss on scholastic achievements.

Background: Development of Arabic QuickSIN established after the need to speech in noise test using was elevated in the last decade. Objective: The purpose of this study was to Develop and standardize Arabic QuickSIN test that measures the signal-tonoise ratio loss. Patients and Methods: 300 Sentences have words that are not highly predictable from the surrounding context. These sentences were recorded by female talker, presented in four-talker babble in three experiments. Study sample: Fifty normal hearing subjects between the ages of 18-40 years. Results: In the first two experiments, the level of a female talker relative to that of four-talker babble was adjusted sentence by sentence to produce 50% correct scores. In experiment III, those sentences-in-babble that produced either lack of equivalence or high across-subject variability in scores were discarded. These experiments produced 10 equivalent lists, each list consists of six sentences, with one sentence at each signal-to-noise ratio of 25, 20, 15, 10, 5, and 0 decebels. Conclusion: A single QuickSIN list takes approximately one minute to administer and provides an estimate of SNR loss.
背景:阿拉伯语QuickSIN的发展是在近十年来对语音噪声测试使用的需求提高之后建立的。目的:建立并规范阿拉伯语信噪比损耗快速测量法。病人和方法:300个句子的单词不能从周围的语境中高度预测。这些句子由女性说话者记录下来,在三个实验中以四人说话者的语言呈现。研究样本:50名年龄在18-40岁之间的正常听力受试者。结果:在前两个实验中,女性说话者相对于四人说话者的水平逐句调整,产生50%的正确率。在实验三中,那些在得分上缺乏对等性或跨主体差异较大的胡言乱语句子被丢弃。这些实验产生了10个等效列表,每个列表由6个句子组成,每个句子的信噪比分别为25、20、15、10、5和0分贝。结论:一个单一的QuickSIN列表大约需要一分钟的时间来管理,并提供信噪比损失的估计。

Background: Alar rim collapse is an agonizing problem that has both cosmetic and functional sequalae. It has been usually addressed with batten grafts. In this study, we are describing a simple technique for insertion of alar rim grafts to fix external nasal valve collapse. Patients and Methods: Between January 2018 and October 2020, eighteen patients with alar rim collapse or deformities were addressed using alar rim septal cartilage grafting. Results: All patients who underwent alar rim grafting for external nasal valve collapse were evaluated functionally and aesthetically with post-operative follow up ranging from 12 to 24 month. During which, they showed marked improvement in their nasal airway patency with complete satisfaction for the aesthetic outcome. No complications were encountered. Conclusion: Alar rim grafting is a simple and effective approach to provide support for the external nasal valve and alar contour. In cases of malpositioned lower lateral cartilage, alar flaring, nasal tip deformities, mild retraction, or contour asymmetries, these cartilage grafts showed good outcomes in primary or revision cases.

Background: Attention Deficit Hyperactivity Disorder (ADHD) refers to the existence of marked difficulties in terms of distractibility, impairment of attention and hyperactivity with a subsequent development of substantial impairment in academic and social functioning. Language impairment (LI)is a predominant co-morbidity in pediatrics with psychiatric illnesses and behavioral troubles. In children with LI, one of the common psychiatric disorders is ADHD. However, LI is a common co-morbidity which often could be detected in ADHD children. Although language problems are not among the main symptoms or needed to fulfill current diagnostic criteria of ADHD, most ADHD children have additional defects in language skills. Objective: The main purpose of the current study was to assess language profile in ADHD children at school age and to specify aspects of language defect in comparison with their normal peers. Patients and Methods: 60 children in the school age (6-10 years) of both genders divided in to two groups, case group: 30 children with ADHD and control group: 30 children without ADHD were enrolled in this case control study. Children were assessed by study tests: 1Stanford Binet [fifth edition], 2ADHD Test 3REAL Scale, 4Phonological Awareness Test, 5Rapid Automatized Naming Test. Results: ADHD children were lower than their normal peers in IQ score, language skills, phonological awareness skills, and rapid automatized naming. Regarding aspects of language, they had defects in many skills: receptive and expressive vocabulary, morphosyntax, sentence comprehension, story comprehension, verbal categorization, sentence repetition, and forming sentences.
背景:注意缺陷多动障碍(Attention Deficit Hyperactivity Disorder, ADHD)是指在注意力不集中、注意力缺陷和多动方面存在明显困难,随后发展为学业和社交功能的严重障碍。语言障碍(LI)是儿科精神疾病和行为障碍的主要合并症。在LI患儿中,常见的精神障碍之一是多动症。然而,LI是一种常见的合并症,通常可以在ADHD儿童中检测到。虽然语言问题不是ADHD的主要症状之一,也不需要满足当前的ADHD诊断标准,但大多数ADHD儿童在语言技能方面还有额外的缺陷。目的:本研究的主要目的是评估学龄期ADHD儿童的语言特征,并将其与正常同龄人的语言缺陷进行比较。患者与方法:60名男女学龄儿童(6-10岁)分为两组,病例组:30名ADHD儿童,对照组:30名非ADHD儿童,进行病例对照研究。采用stanford Binet[第5版]、adhd测试、real量表、语音意识测试、快速自动命名测试对儿童进行评估。结果:ADHD儿童在智商、语言能力、语音意识能力、快速自动命名能力等方面均低于正常儿童。在语言方面,他们在接受和表达词汇、形态句法、句子理解、故事理解、言语分类、句子重复、造句等技能上存在缺陷。

Background /Aims: Stuttering typically emerges in the preschool years as children are experiencing substantial growth in their language and are beginning to combine words to form short sentences. Stuttering occurs during the process of planning utterances and using sounds to create words and sentences. A significant percentage of stutterers had a history of delayed language development and articulation disorders. This study's purpose was to examine differences between children who stutter (CWS) and child who do not stutter (CWNS) on standardized tests of IQ, language test, and articulatory tests. Patients and Methods: An analytic cross sectional study conducted on two groups of subjects. The study group consisted of 52 children (study group) who stutter (CWS) and control group included 52 children who do not stutter (CWNS). Each child in the study group was audio-recorded, which was subsequently assessed by (Arabic version of stuttering severity index "A-SSI") to provide information pertinent to the child's frequency and type of speech dysfluencies. Each child was determined and responded to standardized tests of cognitive, language, and articulatory assessment. Results: There was a significant decrease in receptive, expressive, and total language scores of language test within cases; regards to articulation test, there was a considerable increase of SSDs. These differences in receptive/expressive language and total language scores were significantly correlated with the overall stuttering frequency of cases CWS. Conclusion: Findings were taken to suggest the imbalance among components of the speech-language systems of CWS that may contribute to the difficulties they have establishing usual speech fluency.
背景/目的:口吃通常出现在学龄前,因为孩子们正在经历语言的实质性增长,并开始将单词组合成短句。口吃发生在计划说话和使用声音创造单词和句子的过程中。很大比例的口吃者有语言发育迟缓和发音障碍的病史。本研究的目的是检查口吃儿童(CWS)和非口吃儿童(CWNS)在智商、语言测试和发音测试的标准化测试中的差异。患者和方法:对两组受试者进行分析性横断面研究。研究组包括52名口吃儿童(研究组),对照组包括52名非口吃儿童(CWNS)。研究小组中的每个孩子都被录音,随后通过(阿拉伯语版口吃严重程度指数“A-SSI”)进行评估,以提供与儿童语言障碍的频率和类型相关的信息。每个孩子都被确定并对认知、语言和发音评估的标准化测试做出反应。结果:病例内语言测试的接受性、表达性和总语言分数均有显著下降;在发音测试方面,ssd有了相当大的增加。这些接受/表达语言和语言总分的差异与CWS患者口吃的总体频率显著相关。结论:研究结果表明,CWS语音语言系统各组成部分之间的不平衡可能导致他们难以建立正常的语言流畅性。

Background: Many non-surgical and surgical procedures have been used to treat patients with chronic recurrent temporomandibular joint dislocation (CRTMJD). Autologous blood injection (ABI) represents a promising approach. Aim of the work: To evaluate the effectiveness and safety of ABI in the treatment of patients with CRTMJD. Patients and Methods: This prospective comparative study involved patients with CRTMJD who were treated by arthrocentesis and ABI with those treated with arthrocentesis alone between January 2017 and January 2020. Analysis of clinical presentation, diagnosis, close observation of patients has been carried out. Results: 140 patients were included in this study, 87 were males and 53 were females. Their ages ranged between 16 to 82 years. They were randomly divided into two groups of 70 each. Group-1 received arthrocentesis followed by ABI and Group-2 received arthrocentesis alone. In group-1, only one ABI was required and was successful in 63 patients and reinjection was required in 7 patients. None of the patients need surgery due to re-injection failure. Conclusion: Positive results on this modality were observed, some questions are still noted about the effect of blood injection on the articular cartilage and on the development of fibrous or bony ankylosis.
背景:许多非手术和手术方法已被用于治疗慢性复发性颞下颌关节脱位(CRTMJD)患者。自体血液注射(ABI)是一种很有前途的方法。目的:评价ABI治疗CRTMJD患者的有效性和安全性。患者和方法:这项前瞻性比较研究纳入了2017年1月至2020年1月期间接受关节穿刺和ABI治疗的CRTMJD患者与单独接受关节穿刺治疗的患者。对患者的临床表现、诊断、密切观察进行了分析。结果:本研究纳入140例患者,其中男性87例,女性53例。他们的年龄在16岁到82岁之间。他们被随机分成两组,每组70人。组1先行关节穿刺后行ABI,组2单独行关节穿刺。在1组中,63例患者只需要一次ABI并成功,7例患者需要再注射。没有一例患者因再注射失败而需要手术。结论:该方法疗效显著,但对关节软骨及纤维性或骨性强直的影响尚存疑问。

Introduction: Nasopharyngeal angiofibroma has usual characters regarding its origin, histopathology, vascular feeding and clinical presentation. In this study we have presented some cases of nasopharyngeal angiofibroma with unusual characters. Methods: A case series study that was conducted on patients with angiofibroma presented to otolaryngology department of Cairo University, between 2010 and 2020. Searching for unusual presentation. Results: Thirteen male patients with mean age 12.5 years had shown unusual character. Seven cases showed unusual vascular feeding pattern and six cases showed unusual character of anatomical location and extension (3 cases in whom the tumor is entirely medially located to sphenopalatine foramen and another 3 cases in whom the tumor is entirely laterally located to sphenopalatine foramen) Conclusion: Every day and other rhinologists all over the world report cases of nasopharyngeal angiofibroma. But some uncommon cases do not fulfill the typical epidemiological, pathological and clinical criteria and that is what was presented in this study. This study had highlighted 13 cases of angiofibroma with atypical characters regarding vascular feeding and locoregoinal extension.
