Learning objective At the end of lecture students will be able to know about Congenital anomalies of larynx Diagnosis and their management
Commom Symptoms Of Congenital laryngeal Disorders Stridor Hoarseness Aspiration
CONGENITAL ANOMALIES OF LARYNX Laryngo-malacia Hemangioma Vocal cord paralysis Laryngeal web Subglottic stenosis Tracheo-esophageal fistula Laryngocele
scenario A Mother brought her newly born child in ENT DEPARTMENT with History of stridor which become more prominent on crying and subsides when baby is in prone postion other vise normal cry .on Direct laryngoscopy you see omega shaped EPIGLOTTIS WHATS YOUR DIAGNOSIS IN THIS CASE WHAT ARE CLINICAL FEATURES WHATS ITS MANAGEMENT

LARYNGOMALACIA This is excessive softening( flaccidity)of suprglottic larynx Most common congenital abnormality Stridor increase on crying, decreases in prone position This is commonest cause of stridor in children Condition is seen at birth or soon after birth It disappear at the at of 2 year usually
CAUSES Relaxation or a lack of muscle tone in the upper airway may be a factor. It is often worse when the infant is on his or her back, because the floppy tissues can fall over the airway opening more easily in this position.
Normal larynx
PATHOLOGY Excessive softness and flabbiness Thinning and hypo cellularity of laryngeal cartilages Wrinkled loose edematous mucosa The exaggerated inspiratory effort increases blood return to the pulmonary vascular bed. This could account for the increased likelihood of pulmonary artery hypertension in infants with hypoxemia
CLINICAL FEATURES Stridor is main symptoms that appears at or soon after birth is mainly inspiratory Tubular or omega shaped epiglottis Laryngeal inlet is of cruciate appearance Stridor is more while sleeping Stridor disappears in second or fifth year of life Cyanosis is rare Voice is unchanged
laryngomalacia
DIAGNOSIS Careful history and examination Flexible fiberoptic laryngoscopy Direct laryngoscopy
OMEGA SHAPE EPIGLOTTIS
TREATMENT Re-assurence Symptoms subside after 2-5 year Treatment of URTI often relieves stridor Tracheostomy If needed
SURGICAL TREATMENT Most commonly, this involves cutting the aryepiglottic folds to let the supraglottic airway spring open Supraglottoplasty
supraglottoplasty
Scenario A new born baby with history of forceps delivery presented to ENT department with history of stridor and horsiness cry. What is your diagnosis What your management plan
CONGENITAL ANOMALIES OF LARYNX Laryngo-malacia Hemangioma Vocal cord paralysis Laryngeal web Subglottic stenosis Tracheo-esophageal fistula Laryngocele
Congenital vocal cord paralysis True vocal cord card paralysis is second most common cause of laryngeal anomalies 10-15 % of congenital laryngeal problems is vocal paralysis Symptoms of vocal cord paralysis often show up by 2 months of age It occurs due to birth trauma when recurrent laryngeal nerve stretched during forcep s delivery
BILATERAL (TWO-SIDED) PARALYSIS High pitched, noisy breathing Blue spells Aspiration Shortness of breath with activity
TREATMENT In most circumstances, no immediate treatment is needed for one-sided vocal cord paralysis. Treatment is needed when your child is having breathing difficulty or is aspirating fluid into the lungs.
SCENARIO A MOTHER BROUGHT HER 2 months OLD MALE CHILD WITH HISTORY OF PREMATURE DELIVER AND REMAINED ON VENTILATION FOR 1 MONTH IN ENT DEPARTMENT WITH HISTORY OF RESPIRATORY DISTRESS,STRIDOR ON XRAY NECK SOFT TISSUE ,THERE IS NARROWING OF SUB GLOTTIS WHATS YOUR DIAGNOSIS WHATS MOST COMMON CLINICAL FEATURES WHAT WILL BE YOUR MANAGEMENT PLAN

CONGENITAL SUBGLOTTIC STENOSIS 3 rd most common congenital anomaly Common cause may due to tracheostomy Pathology Sub mucosal tissue thickness Small cricoid or abnormal cricoid cartilage 1 st tracheal ring displacement
CLINICAL FEATURES 1 st week to 1 st month Recurrent or persistent croup Male female ratio 2:1 Stridor Dyspnea
INVESTIGATION AND TREATMENT D L Scopy Bronchoscopy X-Ray soft tissue may show smooth narrowing of subglottis
Preoperative view of 4 month infant aquired stenosis
TREATMENT Tracheostomy if severe distress Dilatation of stenosis repeated Laryngo-tracheo-plasty Laser excision stenting
Split cricoid for sub glottic- stenosis
Post operative view after laser
SCENARIO A MOTHER BROUGHT HER 2 YRS CHILD IN ENT DEPARTMENT WITH HISTORY OF NOISY BREATHING ,RESPIRATORY DISTRESS ,STRIDOR ,OFF AND ON HISTORY OF CYNOSIS ON DIRECT LARYNGOSCOPY U SEE A RED PURPLISH MASS IN SUB GLOTTIS WHATS YOUR CLINICAL DIAGNOSIS WHATS ARE MOST COMMON CLINICAL FEATURES WHATS YOUR MANAGENT PLAN
CONGENITAL ANOMALIES OF LARYNX Laryngo-malacia Hemangioma Vocal cord paralysis Laryngeal web Subglottic stenosis Tracheo-esophageal fistula Laryngocele
HEMENGIOMA OF LARYNX Benign over growth of small blood vessels in subglottis Cavernous type of hemangioma 50% patients also have cutaneous hemangioma Most commonly in females
SYMPTOMS Stridor is biphasic (inspiratory and expiratory) Dyspnea Cyanosis Retraction of intercostal space Symptoms may be absent at birth or appear after URTI Presence of cutaneous hemangioma When small may be asymptomatic
INVESTIGATION CT Scan or MRI show mass in subglottic region Direct laryngoscopy examination Shows RED PURPLRE MASS Cotton soaked gauze with adrenalin causes shrinkage of mass Biopsy is dangerous
TREATMENT Hemengioma have rapid growth from 2-6 month After which regress spontaneously If regression does not take place propranolol Steroids Surgery Laser excision
scenario Mother brought her one month old baby with complaint of shortness of breath,week cry ,and stridor from birth on direct laryngoscopy there is thick membrane between vocal cords Whats your clinical diagnose in this case What are clinical finding,s Whats will be your management plan
CONGENITAL ANOMALIES OF LARYNX Laryngo-malacia Hemangioma Vocal cord paralysis Laryngeal web Subglottic stenosis Tracheo-esophageal fistula Laryngocele
CONGENITAL LARYNGEAL WEB Condition is due to incomplete splitting of vocal cords( incomplete recanalization of larynx) 75% cases web is in the glottic region TYPES Membranous Fibrous
LARYNGEAL WEB
SYMPTOMS AND SIGNS Symptoms vary with size of web Hoarseness Stridor Dyspnea SIGNS Stridor Obstruction IDL Pink thin or thick membrane between vocal cords
TREATMENT Tracheostomy Excision by laryngo-fissure M.C.- Knought- keel between the vocal cords Small web can be excised by MLS Co2 laser therapy Cut with knife
scenario A mother brought her new born pre mature baby in ent department with complaint of feeding difficulty , persistant cough,choking and cyanosis at time of feeding Whats your provisional diagnosis What will be your management plan in this case
CONGENITAL ANOMALIES OF LARYNX Laryngo-malacia Hemangioma Vocal cord paralysis Laryngeal web Subglottic stenosis Tracheo-esophageal fistula Laryngocele
TRACHEOESOPHAGEAL FISTULA Tracheoesphageal septum is deficient(failure of fusion of cricoid lamina) Communication of air and food passage Seen in Premature birth
CLINICAL FEATURES Barking cough Aspiration Choking Feeding difficulty cyanosis
DIAGNOSIS Flexible laryngoscopy Direct laryngoscopy Barium study may show contrast in airway
TREATMENT Intubation or tracheostomy N/G Intubation Antibiotics Surgical repair
SCENARIO A MOTHER WITH HISTORY OF COPD BROUGHT HER MALE BABY BOY WITH HISTORY OF SHORTNESS OF BREATHE ,CYNOSIS OFF AND ON AND STRIDOR WHATS WILL BE YOUR DIAGNOSIS IN THIS CASE WHAT WILL BE TREATMENT PLAN

LARYNGOCELE An air filled dilatation in saccule of laryngeal ventricle Occures in males Deformity is rare in adults Refers to a congenital anomalous air sac communicating with the cavity of the larynx , which may bulge outward on the neck.
PREDISPOSING FACTORS It may be aquired and seen in Glass blowers In patients with COPD Strainig Coughing Playing with wind instruments The activity which increases intralaryngeal pressure
TYPES External cystic mass lateral to thyro-hyoid membrane Internal air containing sac confined to area of false vocal cords mixed
Laryngeocele /cyst
TREATMENT MLS micro-laryngeal surgery Laser excision Open surgical excision Lateral Midline aproach
