Assessment of Preoperative Predictors for Difficult Laryngeal Exposure in Endolaryngeal Surgery.

Introduction: The proper visualisation of the larynx is required for the diagnostic assessment and therapeutic intervention. The most significant challenges for surgeon is to visualise the anterior commissure of the glottis region. The aim of this study is to record the preoperative laryngoscore in patients posted for endolaryngeal surgery and to assess preoperative predictors for intraoperative difficult laryngeal exposure by correlating with preoperative laryngoscore. Design: Prospective, Cross-sectional, Observational study. Setting: Department of Otorhinolaryngology in a tertiary care teaching facility. Subjects: 150 patients were included with an endolaryngeal disease who were planned for surgery with age > 18yrs. Methodology: In 150 subjects preoperative laryngoscore was calculated, which comprised 11 parameters including thyromental distance, mandibular prognathism, macroglossia, micrognathia, trismus, inter incisor gap, degree of neck flexion-extension, history of prior open-neck surgery or radiotherapy, upper jaw dental status, modified Mallampati score and body mass index in order to produce a total score out of a possible maximum score of 17. According to the anterior commissure visualisation all patients were categorised into five classes, ranging from class 0 to class IV during surgery. The laryngoscore parameters were assessed and compared statistically with five classes of intraoperative anterior commissure visualisation. Result: Out of 150 patients 70 (46.6%) were having 3-4 laryngoscore, followed by 45 (30%) patients with 5-6 laryngoscore. Total 123 (82%) patient had class 0,1 and 2 intraoperative anterior commissure visualisation while 27 (18%) had class 3 and 4 visualisation. If laryngoscore was either less or equal to 5, 90% of the patients had excellent laryngeal exposure whereas only 10% of the patients had challenging laryngeal exposure. At univariate analysis, thyromental distance, degree of neck flexion/extension, and modified Mallampati classification were found statistically significant for difficulty of anterior commissure visualisation independently. Conclusion: A sound, easy and valid preoperative laryngoscore may be significantly helpful in identifying intraoperative difficult laryngeal exposure. This may prevent inadequacy of surgery, abandon of surgery, intra operative complication, and medico-legal cases for laryngologist.

Clinico-Etiological Evaluation of Epistaxis.

Epistaxis or bleeding from nose, a commonly confronted condition in the department of otorhinolaryngology can be a disquietening experience and sometimes a life threatening emergency for the patient. The aim of this study is to study the clinical profile and aetiology in epistaxis patients. An observational prospective study carried out over a period of 12 months in the Department of Otorhinolaryngology, Head and Neck Surgery, Swami Rama Himalayan University, Swami Ram Nagar, Dehradun, Uttarakhand. A total of 104 patients of all age groups and gender presenting with epistaxis were included in the study. Males formed majority of the patients (68.27%) as compared to female patients (31.73%). Most of the patients were in the age group of 51-70 years with majority being farmers (30.77%). The finding of variation with age was statistically significant (p < 0.05) with most patients in the age group of 51-60 years presenting in winter season. Local causes were observed to be more common (50.96%) among which trauma was the predominant cause (23.08%). Systemic causes formed 37.58% of cases, out of which hypertension was the commonest cause. In our study, non-surgical measures were most commonly employed treatment modality (85.58%) among which medical management was done in most patients. Trauma and hypertension contributed to the majority of patients presenting with epistaxis in our study with cold, dry winter months associated with increased incidence of epistaxis.

A 4-year Retrospective Review of the Presence and Pattern of Ventricular Hyperadduction Following Unilateral Vocal Fold Paralysis, Paresis, and Unilateral Cordectomy.

BACKGROUND: The aim of our study was to determine the presence and pattern of ventricular hyperadduction (VH) following unilateral vocal fold (VF) paralysis/paresis and that following unilateral cordectomy (UC). METHODS: The authors independently reviewed charts and flexible videostroboscopic recordings of 214 patients diagnosed with unilateral VF paralysis/paresis and those who had undergone UC from 2015 to 2018. The presence and pattern of VH was noted. VH was considered to be present when the false vocal fold (FVF) obliterated 50% or more of the true vocal fold width during phonation, with or without FVF vibration. The true vocal fold width was considered to be that which was visible on abduction of the VFs. Categorical variables were presented in numbers and percentages and qualitative variables were correlated using Chi-Square test. Odds ratio with 95% Confidence Interval was calculated. RESULTS: In 154 patients diagnosed as unilateral VF paralysis/paresis 85 patients had a VH pattern (55.19%) with contralateral VH observed in 74 (87.05%), ipsilateral VH observed in 6 (7.05%) and bilateral VH observed in five patients (5.88 %). The total number of patients of UC was 60 with 36 of these patients developing a VH (60%). Ipsilateral VH was observed in 28 of these 36 patients (77.77%), three patients developed contralateral VH (8.33%) and five patients developed bilateral VH (13.88%). CONCLUSION: Ipsilateral ventricular hyper-adduction following unilateral cordectomy in the group of patients that develop hyperadduction is a significant finding in our study suggesting possibility of unilateral central phonatory control of the FVF. Contralateral ventricular hyper-adduction following unilateral paralysis and paresis, in the group of patients that develop hyperadduction is a significant finding in our study and this finding resonates with previously published papers. A finding of unilateral VH may serve as a possible indicator of the occasionally challenging diagnosis of vocal fold paresis. STUDY TYPE: Retrospective, Observational.

Evaluation of Association of Allergic Rhinitis with Bronchial Asthma.

Allergic rhinitis represents a global health problem. It is a common disease worldwide affecting about 10-50 % of the population and its prevalence is increasing. Although allergic rhinitis is not a fatal disease, it alters the social life of patients, affecting learning performance and work productivity. Moreover, the costs incurred by allergic rhinitis are substantial. In recent years allergic rhinitis has been recognized to be an important risk factor for asthma. The concept of "One Airway, One Disease" was highlighted in the 'Allergic rhinitis and its Impact on Asthma 'guidelines and has arisen as a result of the now well-established link between the upper and lower airways. The aim of this study was to evaluate the association between allergic rhinitis and bronchial asthma by determining the incidence of bronchial asthma in patients of allergic rhinitis and the incidence of allergic rhinitis in patients of bronchial asthma. 83 diagnosed cases each of allergic rhinitis and bronchial asthma were recruited from patients attending Otorhinolaryngology and pulmonary department of the institute. All patients were subjected to detail ENT and pulmonary examination and investigated for nasal and bronchial allergy. In the allergic group, which consisted of 83 diagnosed patients of allergic rhinitis, 49 (59.03 %) were diagnosed to have bronchial asthma, whereas in the bronchial asthma group, which consisted of 83 diagnosed patients of bronchial asthma 61 (78.20 %) were diagnosed to have comorbid allergic rhinitis. It was observed that patients with allergic rhinitis were likely to develop bronchial asthma, and patients of allergic rhinitis should be evaluated for bronchial asthma, for early detection and treatment of the co morbid condition.

Giant Parapharyngeal Space Pleomorphic Adenoma Causing Acute Airway Obstruction.

Primary parapharyngeal space (PPS) tumors are rare, representing only 0.5% of all head and neck neoplasms. About 80% of tumors of this space are benign, and 20% are malignant. They often pose therapeutic and diagnostic problems due to variable non-specific symptoms and the complex anatomy of this space. Pleomorphic adenoma is the most common benign tumor of this space. It presents as an asymptomatic mass causing mild bulging in the soft palate or tonsillar region, or fullness near the angle of the mandible in the neck. We report the case of a 60-year-old male admitted to the emergency department with breathing difficulty and acute stridor. He was unable to maintain oxygen saturation, and an emergency tracheostomy was performed. Radiological and cytological evaluation were performed, and the patient was diagnosed as having primary PPS pleomorphic adenoma. The tumor was excised via the transcervical approach. The rarity of tumor in this space and unusual life-threatening presentation prompted the authors to report this case. To our knowledge, this is the third case reported worldwide of a pleomorphic adenoma causing upper airway obstruction and acute respiratory failure.
