Efficacy of Voice Therapy in Rehabilitation of Muscle Tension Dysphonia in Patients of Nonlaryngeal Head and Neck Cancer: A Sequelae of Chemoradiotherapy.

The association of voice disorders in laryngeal cancers has been studied extensively; however Dysphonia associated with chemo-radiation in non laryngeal Head and Neck cancer (HNC) is a new area of practice in voice clinics. This study thus aimed to evaluate the efficacy of voice rehabilitation among non-laryngeal HNC survivors who were treated with curative RadioTherapy (RT)/Chemoradiotherapy (CRT) in adjunct with or without surgery. This tertiary institutional assessor blinded quasi experimental study after inclusion and exclusion criteria consisted of a study cohort of 128 patients who within 1-3 months of completion of treatment for HNC reported to the laryngology clinic for voice complaints and throat discomfort. All patients underwent documentation of laryngeal endoscopic imaging, acoustics assessment, Aronson's Laryngeal Palpatory Method (LPM) and Voice Handicap Index (VHI). Thereafter they were subjected to Vocal Rehabilitation Therapy (VRT) which constituted of Manual circumlaryngeal therapy, SOVTE, and vocal hygiene program. Re-evaluation of the vocal parameters was done at 6 weeks and 3 months from the start of the VRT. All parameters were significantly altered at 6 weeks and 3 months follow-up. Post VRT the videolaryngoscopic findings showed reduction in abnormal supraglottic MTPs with subsequent good approximation of true cords and reduction of involvement of supralaryngeal activities. The Dysphonia Severity Index (DSI) impairment levels and VHI scores showed significant improvement from the baseline to both at 6 weeks and 3 months of VRT (p < 0.001). DSI and VHI scores even showed significant improvement between 6 weeks to 3 months of therapy. There was highly significant correlation of VRT with/without surgery, with CRT and in non-smokers at 6 weeks and 3 months of VRT. In non-laryngeal head and neck malignancies, VRT offered as early as within 1-3 months of completion of treatment of HNC ameliorates surgical and chemo-radiation induced Muscle Tension Dysphonia.

Surgical Resection of Retrosternal Goitre: The Four-Finger Technique.

Retrosternal goitre (RSG) is a thyroid gland with more than 50% of its mass located below the thoracic inlet. Pre-operative Computed Tomography can visualise the anatomical relations between the RSG and each mediastinal component, and the level of extension. Most cases of RSG can be resected via the cervical approach, as the thoracic approach carries a greater risk of complications. We describe a four finger technique for total thyroidectomy in five cases of RSG through a neck incision, without the need for a sternotomy. The recurrent laryngeal nerve (RLN) was identified early in the Baehr's triangle. The thyroid was mobilised in the neck by ligation of the feeding vessels and separated from the tracheal attachments. The retrosternal portion was then delivered into the neck by blunt dissection, keeping two fingers of each hand close to the thyroid gland. The RLN and parathyroids were identified early in the surgery to avoid the complications of hoarseness and hypoalcemia, respectively.

Association of Cord Ferritin Levels with Brain Stem Evoked Response Audiometry in Newborns.

Iron is an important nutrient and it plays a pivotal role in myelin formation and neurotransmitter synthesis, thus contributing to normal neurological activity. Ferritin is a reliable indicator of the tissue iron stores and in-utero stores can be well measured by cord ferritin levels. The objective of this study was to evaluate the effects of umbilical cord ferritin levels (CFL) on the brain stem evoked response audiometry (BERA) This prospective observational study was conducted in a tertiary care centre of North India with a sample size of 100 inborn neonates. After evaluation of the umbilical cord ferritin levels the study cohort was divided into Group A( UCF<75ng/ml) and Group B(UCF>75ng/dl). All subjects were subjected to BERA. A detailed analysis of CFL and BERA was done and statistically analysed. Neonates in group B had significantly prolonged absolute peak latency of wave I, III and V and interpeak latency of wave III-V when compared to group A. The Pearson correlation also showed negative correlation of CFL with absolute peak latency of wave I, III, and V and interpeak latency of wave III-V. Among the maternal and neonatal variables, highly significant correlation was noted between absolute latency of wave I, III and V, CFL and cord hematocrit. The Pearson correlation showed negative correlation of absolute peak latency of wave I, III and V with maternal haemoglobin (Hb), neonatal birth weight, CFL,s and cord hematocrit values. A negative Pearson correlation was noted between interpeak latency of wave III-V with neonatal birth weight and cord hematocrit level, interpeak latency of wave I-V with neonatal birth weight and between interpeak latency of wave I-III with cord hematocrit values. CFL's significantly affect the absolute peak latency of wave I, III and V and it also affects the interpeak latency of wave III-V. This may be attributed to slow conduction time secondary to altered myelination. CFL's should be considered as a routine protocol in neonates to detect early compromises in the process of myelination and brain maturation.

Muscle Tension Dysphonia: A Sequeale of Chemoradiotherapy in Patients of Head and Neck Cancer.

It's very important to demarcate that voice is the production of sound by the larynx while speech is articulation of the produced sound by tongue movements, soft palate and the lips. Mucositis, dysphagia, change in speech and voice are the common sequelae of Radiotherapy (RT) alone or in combination with chemotherapy (CRT) which is commonly used in the treatment of head and neck cancer (HNC). The aim of this study was to investigate the patient-reported voice impairment among non laryngeal head and neck cancer survivors who were treated with curative RT/CRT with or without surgery. This tertiary institutional assessor blinded study consists of a study cohort of 128 patients who after of completion of treatment for HNC reported to the laryngology clinic for voice complaints and throat discomfort. The assessment included laryngeal endoscopic and stroboscopic imaging, acoustics assessment and VHI (Vocal handicap index). This study cohort consisted of 89.8% males and 11.2% females. There was hyperadduction and strain of ventricular bands in almost all the cases. There was hyperactivity and compression of both true and false cords in 80.5% of the cases. DSI impairment level showed significant association with gender, VHI, GRBAS score and RT/CRT and it did not show significant association with smoking and surgery, while VHI showed significant association with DSI and RT/CRT and it did not show significant association with gender, smoking and surgery. Muscle tension is a very common effect of RT/RCT and dysphonia can be easily associated with it. Future research needs to focus on specific voice treatment regimens in HNC treated with RT/CRT to improve the quality of life of these patients.

Evaluation of Tongue Functions After Free Flap Reconstruction.

Squamous cell carcinoma of the tongue is the most common malignancy of the oral cavity, the lateral border being the commonest site. The treatment strategies mandate surgery followed by appropriate reconstruction as the first line of management. There are many suitable methods of reconstruction of tongue defects after surgery, but the principle of an ideal reconstruction method should provide not only satisfactory structural cosmesis, but also good restoration of function. We present our experience with the skin lined free flaps reconstruction for defects of the tongue and floor of mouth, and present analyses of the functional outcomes of reconstruction. This prospective longitudinal study included 93 patients and was conducted in a tertiary care center in Punjab. All patients underwent free flap reconstruction after tumor removal. The functional outcome of the tongue following reconstruction was evaluated 9 months after the completion of treatment. Functions were assessed and matched with sexes and age-matched normal individuals. The data obtained were analyzed by the student 't' test and the p values < 0.05 were considered statistically significant. The duration of swallowing in patients with FRF flap and ALT flap when compared to the normative was significant (< 0.05). There were changes in configuration and volume of the oral cavity after surgery which generates resonant and articulatory alterations, thus the intelligibility of the patient's speech is lowered. There is also a restriction in the tongue movements and reduction in the sensations of the reconstructed part of the tongue. Both the free ALT flap and the FRF flap can provide acceptable functional restoration of the tongue after radical tumor resection.

Impact of Hyoid Position, Mandible Body Length and Anthropometric Measurements on Sleep Indices in Patients with Snoring in North Indian Population.

Introduction: In Indian population, the estimated prevalence of OSA is 7.5% to 13.5%. Craniofacial anatomical variations and obesity are the major risk factors for OSA. Among the craniofacial anatomy, the neck circumference and abnormal craniofacial morphology play an important role in the pathogenesis of OSA. Obesity is the major risk factor for which waist and hip circumference and BMI are considered. Aim: The aim of this paper was to evaluate the impact of hyoid position, mandible body length (MBL) and anthropometric measurements on sleep indices in patients with snoring in North Indian population. Methods: In this cross-sectional study, we analyzed the position of the hyoid, mandible body length and anthropometric measurements, of 104 patients attending ENT OPD with the complaint of snoring and excessive daytime sleepiness. All subjects underwent a full overnight polysomnography. The position of the hyoid, MBL and the anthropometric measurements were compared with the sleep architecture of the subjects, and a p value < 0.05 was considered significant. Results: A strong positive correlation is seen between the position of the hyoid, MBL and anthropometric measurements on the sleep indices in this study. Pearson 2-tailed correlation was evaluated, and upon analysis, it was found that at significance level of 0.01, obesity (BMI) is strongly correlated with overall AHI with correlation coefficient of 0.926, whereas AHI in supine position was having coefficient of 0.837 and AHI on right side and left side was almost same 0.597 and 0.575, respectively. Similarly WC is strongly correlated with AHI and RDI, having coefficient of 0.930 with both. NC and HC also showed strong positive correlation with overall AHI and RDI having correlation coefficient of 0.893, 0.926 with AHI and 0.893, 0.926 with RDI, respectively. The MBL also showed a strong positive correlation with AHI and RDI with correlation coefficient of 0.994 in both. The position of the hyoid also showed a strong positive correlation with AHI and RDI. Conclusion: Results indicated that significant positive correlation was found between position of the hyoid, MBL and anthropometric measurements on the sleep indices in patients with snoring in North Indian population.

High Frequency Hearing Loss in Chronic Renal Disease: A Cross-Sectional Study.

Introduction Chronic kidney disease (CKD) patients face multiple complications. One of them is involvement of the auditory system and it deserves more attention than is paid by the current approaches as hearing loss has major repercussions on the quality of life. Early detection can prevent further deterioration of hearing and improve the quality of life of patients suffering from CKD. Material and methods The high frequency (8-18 kHz) audiometry with pure tones was performed in 82 patients with CKD and compared with age and sexes matched healthy control group of 90 patients. Individual ear were used for statistical calculations. Results This study clearly observed that the hearing thresholds for frequencies 8-18 kHz increased in CKD patients when compared to sex and aged matched healthy control group, the thresholds significantly increased in CKD with diabetes mellitus as compared to nondiabetic with CKD. The high frequency thresholds significantly increased in patients on hemodialysis, and were significantly correlated with age, stage of CKD and duration of CKD. Conclusion This study highlights the presence of high frequency (8-18 kHz) hearing loss in patients of CKD. The severity is significantly correlated with age, stage and duration of CKD.

Expression of Cyclin-D1 and p53 as Prognostic Markers in Treatment of Oral Squamous Cell Carcinoma.

Cyclin D1 and p53 play an important role in tumorigenesis of human cancers. The present study aims to evaluate cyclin D1 and p53 expression in resectable OSCC, and to determine their prognostic significance at the end of 5 year follow-up: A total of 100 patients aged 31-74 years, stage 3/4 were recruited. Cyclin D1 and p53 expression in the tumour tissue was estimated by IHC and was statistically correlated with demographic and clinicopathological data and prognosis was evaluated at the end of 5 year outcome. The positive expression rate of cyclin D1 was 50% and p53 it was 40% and they neither showed any statistical significant correlation with each other nor with demographic or clinicopathological data. The OS was 32%.Negative and weak expression predicted better outcomes with regard to DFS and OS. DFS and OS were significantly worse in patients of overexpressed cyclin D1 (p < 0.001) and p53 (p = 0.008). Cyclin D1 is a better prognostic marker as compared to p53 for both DFS and OS. p53 expression (high versus low) for disease free non-survival and overall nonsurvival showed an OR of 3.576 (p = 0.003) and 8.803(p < 0.001) respectively for strong expression while in case of cyclin D1 it showed an OR of 13.067(p < 0.001) and 37.465(p < 0.001) for strong expression.So higher the level of expression of tumour markers higher is the odds ratio so poorer is the prognosis. Overexpression of cyclin D1 and p53 was significantly associated with poor prognosis in terms of DFS and OS.

Chondrosarcoma of Mandible: A Rare Case Report.

INTRODUCTION: Chondrosarcomas (CS) are malignant mesenchymal tumours with cartilaginous differentiation that rarely affects the maxillofacial region. It accounts for approximately 10-20% of malignant bone tumours. The CS is rare in occurrence with aggressive course with high malignant potential, and poor prognosis. CASE REPORT: Here we report a rare case of a 37year old female presenting tumoral mass in the lower jaw, for the past 3 years, which was gradually progressive in nature with an area of skin ulceration. The CT revealed a well- defined lesion with soft tissue component measuring 15x12x10 cm in size infiltrating both right and left masseter. Biopsy confirmed the diagnosis of grade IIICS. Considering the size and aggressive nature of the lesion, surgical resection was done. The reconstruction of the mandible was done with vascularised fibula pedicle flap to achieve acceptable cosmesis. The patient was discharged uneventfully. Though few cases of high grade CS have been reported in literature but CS of this enormous size has not been reported yet. CONCLUSION: In this case report we documented the management of a relatively rare but challenging reconstructive maxillofacial surgery. Since in this case the CS was enormous in size and aggressive surgery was required, the cosmetic and functional outcomes were challenging. In our case report we have found that a vascularised fibula pedicle flap gives a good functional and cosmetic outcome and can be used for reconstruction of complete mandible.

Adverse Cochlear Effects After Head and Neck Cancer Therapy.

This study aims to report the incidence of adverse cochlear effects when treating patients of HNSCC with different radiation techniques and to compare the effect of different treatment modalities on the cochlea. This prospective observational study took place in a tertiary care centre, of 132 individual ears from 66 patients of HNSCC treated with conventional RT (group-1), IMRT (group-2), conventional RT with chemotherapy (group-3) and IMRT in combination with chemotherapy (group-4). Pure tone audiometry was performed during the follow-up period at 3 months and 1 year of completion of therapy. Correlation of audiometric change of both the ears at high frequencies (pure tone average 4 kHz, 6 kHz, 8 kHz), low frequencies (pure tone average 0.5-2 kHz) and BC (average 500-4 kHz) with series of factors were analyzed. There was a significant deterioration of hearing threshold 1 year after complete treatment, in all groups. There was an average drop in BC (0-1 year) by 19.63 ± 31.25% in group-2, 24.57 ± 21.96% in group-1 and a drop of 36.48 ± 43.97% and 70.78 ± 21.11% in group-3 and group-4 respectively. When we compared the audiometric change (PTAv at high and low frequency) from 0 to 1 year of group-1&2 the p value was significant (p = 0.050 at high frequency, p = 0.040 at low frequency). The audiological outcome of the different treatment modalities when compared, it was observed that the maximum hearing loss was in group-4 (IMRT with Chemotherapy) followed by group-3 (RTCT), group-1 (Conventional RT) and group-2 (IMRT).

Ortner's Syndrome-A Rare Cause of Hoarseness: Its Importance to an Otorhinolaryngologist.

INTRODUCTION: Cardiovocal hoarseness (Ortner's syndrome) is hoarseness of voice due to recurrent laryngeal nerve involvement secondary to cardiovascular disease. Recurrent laryngeal nerve in its course (especially the left side) follows a path that brings it in close proximity to numerous structures. These structures interfere with its function by pressure or by disruption of the nerve caused by disease invading the nerve. However painless asymptomatic intramural hematoma of the aortic arch, causing hoarseness as the only symptom, is a rare presentation as in this case. CASE REPORT: We report a case of silent aortic intramural hematoma which manifested as hoarseness as the only presenting symptom. A detailed history and thorough clinical examination could not reveal the pathology of hoarseness. The cause of hoarseness was diagnosed as aortic intramural hematoma on contrast computed tomography. Thus the patient was diagnosed as case of cardiovocal hoarseness (Ortner's syndrome) secondary to aortic intramural hematoma. CONCLUSION: A silent aortic intramural hematoma with hoarseness as the only presenting symptom is very rare. This particular case report holds lot of significance to an otolaryngologist as he should be aware of this entity and should always consider it in the differential diagnosis of hoarseness.

Audiological Outcome of Classical Adenoidectomy versus Endoscopically-Assisted Adenoidectomy using a Microdebrider.

INTRODUCTION: The aim of this study was to evaluate audiological outcomes following adenoidectomy by the classical method and by endoscopically-assisted adenoidectomy using a powered instrument (microdebrider). MATERIALS AND METHODS: This study was conducted in a tertiary care center. It included 40 patients divided into two equal groups of 20 each. Group-A patients underwent classical adenoidectomy, while Group-B patients were subjected to endoscopically-assisted adenoidectomy using a microdebrider. Hearing outcome was measured by post-operative pure-tone audiometry and tympanometry. RESULTS: The post-operative average air-bone gap (ABG) was reduced from 19.6 dB to 11.8 dB in Group A and from 17.6 dB to 8.7 dB in Group B (P=0.010). There was reversal of tympanometric curves from type-B and type-C to type-A in 55% of the patients in Group A, while type-A curve was seen in 90% cases in Group B in the post-operative period. CONCLUSION: Audiological outcomes of endoscopically-assisted adenoidectomy using a microdebrider were superior compared with classical adenoidectomy.

Changing Trends in Adenoidectomy.

Adenoid hypertrophy treatment is must to alleviate chronic nasal obstruction, mouth breathing, rhinosinusitis and eustachian tube dysfunction. For proper management of this clinical entity a thorough clinical examination along with radiological and endoscopic evaluation is mandatory. Although, few children having adenoid hypertrophy respond to medical treatment, surgery remains the mainstay. An adenoidectomy can be performed by variety of techniques. Conventional adenoidectomy is by the curettage method, still practiced in many institutions, though, a recent technique of endoscopic assisted adenoidectomy by microdebrider is also getting popularized. Both the techniques have their own merits and demerits. However, which of the two surgical techniques is better, is still a matter of preference and experience of the surgeon with the technique. In the present study we will compare the conventional curettage adenoidectomy with endoscopically assisted adenoidectomy done with microdebrider in 40 pediatric patients of adenoid hypertrophy.

A silent nasal mass with ophthalmic presentation.

Nasal chondromesenchymal hamartoma (NCMH) is a rare benign pediatric hamartoma that can simulate malignancy. It is apt to be misdiagnosed because of the overlapping histologic features shared with a number of benign and malignant soft tissue tumors. Here we report a case of this clinical entity in a child of 2.5 years of age. NCMH is histologically characterized by a mixture of various mesenchymal elements, including spindle cells, collagen fibers and irregular islands of osseous and chondroid tissue. The tissue was immunosensitive to SMA and calponin. This tumor has a benign biological behavior, and complete resection is the treatment of choice. Awareness of this clinical entity is essential for correct diagnosis and to avoid potentially harmful therapies.
