January-April 2014, 30(1):1-4
DOI:10.4103/1012-5574.127183  
Hypothesis Different techniques used in cartilage tympanoplasty are palisade technique, shield graft, in-lay butterfly graft, and island flap cartilage. Purpose The aim of the study was to compare audiological and graft take results in partial versus complete strip cartilage reinforcement tympanoplasty. Materials and methods A total of 60 patients with central perforation of the tympanic membrane and age ranging from 18 to 40 years were selected. They were divided into two equal study groups of 30 patients each. The first group underwent complete strip cartilage reinforcement tympanoplasty and the second group underwent partial strip cartilage reinforcement tympanoplasty. Results The overall success rate was 83.3% in the complete strip technique and 86.66% in the partial strip technique. In both study groups, there was statistically significant difference between the audiological results before and after operation. Furthermore, audiological and graft take results were better in the partial strip technique but with no statistically significant difference. Conclusion The overall results of partial strip tympanoplasty are better than complete strip tympanoplasty regarding graft take and audiological results.

Nassim Talaat, Sherif Safwat, Nader Naguib, Fady Ghareb
January-April 2014, 30(1):10-16
DOI:10.4103/1012-5574.127185  
Objective The aim of this study was to propose a proper and standardized protocol for the management of patients diagnosed with orbital complications of sinus origin. This depends on the original clinical diagnosis, or as the patient sent from the ophthalmology department, after computerized tomography, and sometimes pathology, some cases proved to be of nonsinus origin. Materials and methods This is a retrospective study that included 62 patients diagnosed with orbital complications of sinus origin and treated in the last 8 years; the data collected included medical history, detailed examination including endoscopic findings, radiological results, and finding at surgical intervention if performed. Follow-up data were collected for at least 6 months after management. Results Sinusitis of different etiologies can affect the orbit, affection is not always by direct extension, and the orbit may also be affected by noninfectious lesions from the sinuses. Conclusion Proper management of orbital complications of sinusitis requires meticulous assessment of history, examination, and radiology for a proper diagnosis without delay that may adversely affect vision.

DOI:10.4103/1012-5574.127186  
Background More than 80 species of fungi are suspected of inducing immunoglobulin E (IgE)-mediated hypersensitivity. Exposure to airborne fungal conidia has been linked to the respiratory symptoms in individuals with fungal allergy; however, the contribution of airborne fungal hyphae and hyphal fragments to allergic diseases is poorly understood. Objective We sought to investigate the expression of allergens from airborne fungal hyphae and hyphal fragments using the halogen immunoassay, which uses patients' serum IgE to immunostain immobilized allergens extracted from individual fungal particles. Materials and methods Airborne fungi were collected from the nasal cavities of 25 patients and 10 controls using the refined nasal wash technique, fixed on mixed cellulose ester protein-binding membranes, incubated overnight in a humid chamber to promote the germination of conidia, and immunostained with the participants own serum IgE. The samples were examined by means of light microscopy, and positively immunostained fungal particles were classified and counted. Results All samples contained fungal particles that expressed soluble allergens and were significantly higher in concentration than counts of conidia of individual well-characterized allergenic genera (P < 0.05). Resultant immunostaining of fungal hyphae was heterogeneous, and ∼27% of all hyphae expressed detectable allergens compared with nonstained hyphae (P < 0.05). Conclusion This study conclusively demonstrates that fungal hyphae and fragments are underestimated sources of aeroallergens because positively immunostained hyphal fragments were detected in all samples and the number of the detected fungal hyphae in any of the individual protein-binding membranes was significantly higher than the conidial counts in any of the commonly recognized aeroallergenic species.

Mohamed A Hegazy, Ahmed S Mohamed, Ahmed Y El-Hennawy, Mahmoud S El-Fouly
January-April 2014, 30(1):23-29
DOI:10.4103/1012-5574.127189  
Aim of Work In the present study, indications, outcomes, and complications of partial inferior turbinectomy were studied, along with histopathological analysis of the resected turbinate. Methods A total of 20 patients with inferior turbinate hypertrophy were evaluated before and after surgery. Results Clinical evaluation of partial turbinectomy showed that 100% of patients were relieved of their symptoms either completely or partially. None of the patients experienced a worsening of their symptoms after surgery. Complications of this surgery are also fewer and patients can be managed conservatively either by regular follow-up or through proper postoperative instructions. Histopathological evaluation of the turbinate specimens revealed both mucosa and bone as being contributors toward hypertrophy in allergic rhinitis patients more than in patients with inferior turbinate hypertrophy with a deviated nasal septum.

Mohamed T El Tabbakh, Mohamed R Ahmed, Doaa F Sedik, Diaa El Hennawi
January-April 2014, 30(1):30-33
DOI:10.4103/1012-5574.127196  
Background Suez Canal University Hospital, which is the only tertiary care facility in the Suez Canal and Sinai area, is estimated to service more than 5 million patients. Cancer of the larynx, which is the most common head and neck cancer, is also the most common tumor presented to the otolaryngology departments. Aim To evaluate the results of interventional protocols for patients with cancer of the larynx treated in Suez Canal University Hospital. Patients and methods This was a retrospective study carried out on 53 patients with cancer of the larynx reviewed from 1 January 2007 to 1 January 2012 according to demographic, clinical, radiological, operative, pathological data, and possible complications. Results Fifty-three patients, mean age 58 years (71.1% were from urban areas), were studied. The main presenting symptom was hoarseness of voice (66%). Glottis carcinoma was the most common type of cancer found in 41.1% patients. Stage IVa was the most common presenting stage in 39.6% of the patients. Emergent tracheostomy was performed for 39.6% of the patients. According to the treatment protocol, single treatment modality was recommended for 38 (71.6%) patients: 17 (32%) patients were recommended total laryngectomy, followed by radiotherapy in 11 (20.7%) patients, chemotherapy was recommended for eight (15.1%) patients, concurrent chemoradiotherapy was offered to one (1.9%) patient, and partial laryngectomy with preservation of both arytenoids was offered to one (1.9%) patient. In addition, 15 (28.4%) patients were subjected to combined therapy: total laryngectomy combined with radiotherapy in nine (17%) patients and total laryngectomy with chemoradiotherapy in six (11.4%) patients. Conclusion Although the standards of management of laryngeal carcinoma in Suez Canal University hospital are almost in compliance with regional and international standards, we need to deal with the time delay between the diagnosis and definitive treatment to revise the items in the medical records and its registration.

DOI:10.4103/1012-5574.127197  
Introduction Recurrent laryngeal nerve identification is an essential step in thyroid surgery for preserving the patients' voice and thus their quality of life. Methods of dissection and identification are adopted according to the surgeon's preference. Objective The aim of the study was to demonstrate the efficacy of recurrent laryngeal nerve identification using the Zuckerkandl tubercle as an anatomical landmark in comparison with the usual inferosuperior dissection of the tracheoesophageal groove. Patients and methods Four-hundred patients undergoing thyroidectomy were enrolled in a prospective comparative study. They were divided into two equal groups, each group being subjected to a specific technique. Results and conclusion There was a nonsignificant statistical difference between the two techniques, thus validating the efficacy of Zuckerkandl tubercle as an anatomical landmark for identification of the recurrent laryngeal nerve. Level of evidence Ib.

Ismail Zohdi Mostafa, Mohamed Ibrahim Shabana, Amira Maged El Shennawy, Hoda Mahmoud Weheiba
January-April 2014, 30(1):38-42
DOI:10.4103/1012-5574.127200  
Background Cortical auditory evoked potentials (CAEPs) are noninvasive measures used to quantify central auditory system function in humans. More specifically, the P1-N1-P2 CAEP has a unique role in identifying a central auditory system that has benefited from amplification or implantation. P1 reflects the maturation of the auditory system in general as it has developed over time. Objective The objective of this study was to assess the CAEP in children with hearing aids versus age-matched controls, and to compare the pattern of P1 CAEP in patients with hearing aids versus those with cochlear implants. Materials and methods Twenty hearing-impaired children (using their own binaural digital hearing aids) were compared with 20 age-matched and sex-matched children with normal hearing. In both groups, P1 CAEP latency and waveform morphology were recorded by free-field auditory stimulation using tone bursts at 500 and 2000 Hz at 100 dB sound pressure level. Finally, P1 CAEP was compared between patients using hearing aids and 20 children with cochlear implants. Results We have assessed the use of P1 latency and CAEP waveform morphology in a total of 20 children with hearing aids as a biomarker for the development of the central auditory pathway in patients with hearing loss. Children using hearing aids exhibited an exponential decay in P1 latencies, indicating an overall delay in maturation when compared with that in children with normal hearing. There was no statistically significant difference as regards P1 latencies and amplitudes between cochlear implant and hearing aid users, who showed statistically significantly higher mean values compared with the normal group. Conclusion Children's auditory systems develop comparatively as long as they are receiving appropriate amplification, whether this is through a cochlear implant or through the use of hearing aids. The P1 CAEP test can be applied as a tool in the diagnosis of central processing disorders in children with hearing impairments fitted with cochlear implants or hearing aids. This information will be useful when monitoring a child's progress with his hearing device and in auditory training.

Eman Abdel-Fattah Said
January-April 2014, 30(1):43-52
DOI:10.4103/1012-5574.127203  
Background The clinical course and prognosis in sensorineural hearing loss (SNHL) may be even worse if the vestibular system is also involved, especially because of near location of the anatomic structures in the inner ear. However, vestibular function in children with SNHL appears to be under-reported. The aim of the study was to assess the vestibular function and to determine the prognostic value of some etiological, audiological, and demographic (age, sex) factors in predicting a possibility of vestibular impairment for very early identification of children with vestibular deficits. Materials and methods The control group consisted of 30 children with normal hearing (17 girls and 13 boys) and the study group consisted of 50 children with varying degrees of bilateral SNHL, aged between 5 and 15 years. All of them were subjected to the following: basic audiological evaluation (pure-tone, speech audiometry), immittancemetry and auditory brainstem responses, electronystagmography (ENG), and vestibular-evoked myogenic potential (VEMP). Results Hearing impaired (HI) children showed bilateral SNHL of various degrees ranging from moderate to profound hearing loss (HL) [moderate-severe (32%), severe (18%), and profound (50%)] and of different etiologies [heredofamilial (46%), acquired (38%), not known (16%)]. Abnormal ENG findings were recorded in 64% of HI children. Abnormal caloric test findings were found in 56% of the HI children with heredofamilial cause of HL, in 84.2% with acquired HL, and in 37.5% with unknown cause. These results according to the degree of HL were 37.5, 55.5, and 76% for moderate, severe, and profound HL, respectively. It was noticed that HI children with profound degree and acquired etiology of HL had the highest abnormal caloric findings. Abnormal VEMP was found in 72% of HI children, but this percentage varied according to the different etiologies, 56.5, 84, and 75% for heredofamilial, acquired, and unknown, respectively. Bilateral saccular affections were more common than unilateral. HI children with profound HL had the highest percentage of both bilateral and unilateral saccular affections in the absence of VEMP. Conclusion Vestibular deficits occur in a significant percentage of HI children. Abnormal ENG and VEMP findings in HI children varied according to the etiology and or the degree of HL; those with acquired etiology and/or profound degree of HL had the highest abnormal scores.

DOI:10.4103/1012-5574.127184  
Aim The aim of this study is to evaluate the effect of radiotherapy (RT) as one of the modalities of treatment in patients with head and neck tumors on the Eustachian tube and middle ear. Study design This is a prospective study. Material and methods This study included 20 patients suffering from squamous cell carcinoma of the head and neck other than nasopharynx and parotid. They were treated either by surgery and postoperative radiotherapy or by primary radiotherapy alone or by concomitant chemoradiotherapy. Audiological evaluation was performed both pre-treatment and post- treatment in the form of pure tone threshold audiometry (PTA), tympanometry, stapedius acoustic reflex and eustachian tube (ET) function test. Results The 20 patients corresponded to 40 ears which were analyzed. Post RT tympanometry done revealed 16 (40%) ears with normal type A tympanogram and 24 (60%) ears with abnormal tympanometry findings, Post RT ET function test done revealed 7 (17.5%) ears with good ET function and 33 (82.5%) with abnormal ET function, acoustic reflex done post RT revealed 36 (90%) ears with absent acoustic reflex bilaterally and 4 (10%) ears with preserved acoustic reflex and Post RT PTA done revealed 16 (40%) ears with normal PTA, 13 (32.5%) ears with conductive hearing loss (CHL), 8 (20%) ears with sensori neural hearing loss (SNHL) and 3 (7.5%) ears with mixed hearing loss. Conclusion Patients with head and neck tumors given RT as one of the modalities of treatment have a high incidence of affection of middle ear function and ET dysfunction as well as development of CHL.

Eman S Hassan
January-April 2014, 30(1):53-57
DOI:10.4103/1012-5574.127207  
Objective This study was conducted to investigate the effect of chronic renal failure (CRF) on acoustic and aerodynamic parameters of voice and to compare the results with a group of individuals with normal renal function. Design The participants in this study were divided into two groups. A clinical group (the patient group) consisted of 66 adults diagnosed as having CRF (26 male patients and 40 female patients), with their age ranging from 19 to 68 years. The control group consisted of 66 healthy adults (36 male individuals and 30 female individuals). Their age ranged from 20 to 60 years and they did not have any impairment in renal function or any complaints concerning their voice. All participants underwent evaluation of their voice acoustically and aerodynamically. Acoustic analysis was performed using computerized speech lab. The acoustic parameters studied include average pitch, jitter, shimmer, and noise-to-harmonic ratio. Aerodynamic analysis was performed using Aerophone II Model 6800. The aerodynamic parameters studied include vital capacity, maximum phonation time, phonation quotient, mean flow rate, subglottic pressure, and glottal efficiency. The data were analyzed using the independent t-test to compare the significance of difference between means across the two groups. Results In acoustic analysis, there was a significant increase in pitch in male patients with CRF and an increase in shimmer with borderline significance in the total group with CRF. The total group as well as the female subgroup with CRF showed a significant increase in noise-to-harmonic ratio. With respect to the aerodynamic analysis, the total group as well as the male and female subgroups with CRF showed a significant decrease in the vital capacity. There was also a significant decrease in the maximum phonation time in the total and female subgroup with CRF. Conclusion Participants with CRF exhibit clinical evidence of voice disorders both acoustically and aerodynamically. Hence, the present study sheds light on the interplay of different body systems and laryngeal muscles.
