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.

Effect of Adenotonsillectomy on Peak Expiratory Flow Rate Among Children.

Adenotonsillar hypertrophy is one of the commonest causes of upper airway obstruction in children. It can cause hypoxic state by impairing pulmonary functions. Peak expiratory flow rate is a basic, convenient and reliable indicator of pulmonary function in children. To study the improvement in pulmonary functions by assessing Peak expiratory flow rate, before and after adenotonsillectomy in children. DESIGN: Cross sectional, prospective, observational study. SETTING: Department of otorhinolaryngology in tertiary care centre. SUBJECTS: Included 40 children aged between 5 and 15 years, who had adenotonsillar hypertrophy and underwent adenotonsillectomy. METHOD: Diagnostic nasal endoscopy and X-ray, nasopharynx, was done to assess the grade of adenoid hypertrophy endoscopically and radiologically respectively. Peak expiratory flow rate was assessed using Mini Wright peak expiratory flow meter pre-operatively and 1 month post-operatively and both the readings were compared. Subjective improvement was also compared pre-operatively and post-operatively using visual analogue score. This study included 40 patients with male to female ratio of 1.6:1, 92.5% presented with mouth breathing. 92.5% presented with grade III tonsillar hypertrophy and 70% with grade III adenoid hypertrophy endoscopically. After adenotonsillectomy, improvement in Peak expiratory flow rate ranged from 16 to 25.3% which was statistically significant. Patients with grade III tonsillar and grade IV adenoid hypertrophy showed 25.3% improvement. Subjective improvement was 98.8% in the complaint of snoring. Adenotonsillectomy significantly improves pulmonary functions. This may help to improve physical and cognitive development in children and decrease chances of getting cardiopulmonary problems in later life.

Missing Aspirated Impacted Denture Requiring Tracheotomy for Removal.

INTRODUCTION: Aspirated foreign bodies continue to present challenges to otorhinolaryngologists. Removal of impacted airway foreign bodies via conventional methods can at times pose difficulty. This may be related to the location and type of foreign body, experience of the surgeon and anesthetist, and the availability of appropriate instruments. In adults, especially in edentulous patients, a swallowed denture usually gets lodged in the esophagus and entrance into the airway is uncommon. CASE REPORT: We report a case of an uncommon foreign body (3-toothed artificial denture plate) impacted in the trachea of a 40-year-old male following an acute episode of an epileptic attack in which conventional methods of foreign body removal had failed. It was eventually removed via a direct laryngoscopy and tracheotomy technique. CONCLUSION: This type of impaction of a large denture in the trachea is uncommon and late presentation after aspiration is even more rare. This unusual case of a foreign body in the airway is interesting due to its rarity, mode of entry, site of impaction, variable clinical presentation, and method of removal; and hence, prompted the authors to report this case.

Labyrinthine fistula: a complication of chronic suppurative otitis media.

A labyrinthine fistula is a frequent complication of long-standing unsafe chronic suppurative otitis media. It is characterized by a slowly progressive erosion of the bony labyrinth. In this paper we present our observations regarding the diagnosis and management in 50 patients with unsafe chronic suppurative otitis media with labyrinthine fistula.
