About This Presentation

Description : Check out this medical PowerPoint presentation titled "Chronic laryngitis".

This medical PowerPoint presentation is about chronic laryngitis, a condition in which the larynx (voice box) becomes inflamed and irritated for an extended period of time, typically more than three weeks. It is often caused by overuse or misuse of the voice, such as speaking loudly or shouting for long periods of time. Other common causes of chronic laryngitis include acid reflux, allergies, smoking, and exposure to irritants like dust and chemicals.

Symptoms of chronic laryngitis can include hoarseness, a weak or raspy voice, a sore throat, a dry cough, and difficulty swallowing. Treatment typically involves identifying and addressing the underlying cause of the condition, such as reducing voice use or avoiding irritants, treating acid reflux or allergies, quitting smoking, or using medications to reduce inflammation. In some cases, speech therapy or surgery may be recommended.

It is important to see a doctor if you have symptoms of chronic laryngitis, as it can sometimes be a sign of a more serious condition, such as throat cancer. Your doctor can perform a physical exam and recommend appropriate treatment based on your individual situation.

Transcript

Slide 1-

Chronic laryngitis Chronic laryngitis refers to an inflammatory process that determines irreversible alterations of the laryngeal mucosa Reactive and reparative processes of the larynx represent the main pathogenetic factor, which can persist even when the causative stimulus ends
Slide 2-

Non specific : No specific detectable cause Chronic hyperemic Ch Hypertrophic Atrophic Pachydermia (contact granuloma / contact ulcer ) Specific  Chronic granulomatous lesions e.g. Tuberculosis, Syphilis, Scleroma, leprosy, fungal infections & amyloidosis
Slide 3-

Chronic Hyperemic laryngitis Diffuse inflammatory condition involving the whole larynx particularly true & False vocal cords
Slide 4-

Causes Recurrent acute laryngitis / Incompletely resolved Ac laryngitis more than 3 weeks Chronic infection in the vicinity sinusitis, tonsillitis, bad orodental hygiene , Ch Bronchitis Occupational factors  dust & Fumes Smoking & Alcohol Voice abuse GERD
Slide 5-

Clinical Features Males affected more than females Hoarseness of voice Fatigue of voice Hawking & irritation larynx Dry irritating cough Laryngoscopy Hyperemia , Vocal cords appear dull & edges are rounded, Viscid secretions on VC / interarytnoid region
Slide 6-

Slide 7-

Treatment Eliminate The cause  infection / irritating factors Complete voice rest / Observe proper vocal hygiene Medicated steam inhalation ? Expectorants
Slide 8-

Chronic hypertrophic laryngitis Advanced stage of hyperemic laryngitis Cellular infiltrate in the submucosa Epithelium may undergo hyperplasia / metaplasia May be generalized involvement False VC (ventricular bands)  “Dysphonia plica ventricularis” True vocal cords  Rinke’s Edema
Slide 9-

Causes  As for hyperemic chronic laryngitis Laryngoscopy  Laryngeal mucosa is thickened & dusky red in colour Vocal cords red & swollen, Edges loose sharp demarcation In Dysphonia plica venticularis false vocal cords swollen, may cover true VCs
Slide 10-

Treatment Conservative Surgical  Stripping of edematous mucosa with micro-scissor Ablation with LASER One side done at a time to prevent Web
Slide 11-

Atrophic laryngitis Common in women Associated with Atrophic Rhinitis Laryngitis Sicca Exact cause not known  Hormonal disturbance, Dietary deficiency, Autoimmune disorder Bacillus ozaenae secondary infection
Slide 12-

Clinical features Hoarseness Dry irritating cough Dyspnoea due to crusts Laryngoscopy  Laryngeal mucosa is dry & atrophic Covered with foul smelling crusts
Slide 13-

Treatment Primary condition  Atrophic rhinitis Steam inhalation 25% glucose in glycerin sprays Expectorants containing Iodides to loosen the crusts
Slide 14-

Tuberculous laryngitis Secondary to Pulmonary tuberculosis Common in adult males Brochogenic / hematogenous route Bronchogenic route affects posterior larynx --- Interarytnoid region, submucosal tubercles & granuloma Hematogenous  Multiple painful ulcers in larynx & pharynx
Slide 15-

Clinical features Hoarseness Painful ulcers / referred otalgia Odynophagia Laryngoscopy  Pale granulations in the interarytnoid region
Slide 16-

Ulcers of vocal cords  mouse eaten appearance Swelling of false VCs & Aryepiglottic folds X-Ray chest Sputum for AFB Biopsy Treatment : As for pulmonary tuberculosis
Slide 17-

Vocal Nodules Singer‘ nodules Common in voice misusers  Teachers, singers, preachers & Vendors Vocal trauma  submucosal hemorrhage  fibrosis & hyalinization At the junction of anterior 1/3 7 posterior 2/3 ( subject to maximum trauma )
Slide 18-

Clinical features H/o misuse of voice Hoarseness Vocal fatigue Laryngoscopy  Symmetrical nodular pinkish or grey masses at junction of ant 1/3 & post 2/3 of true vocal cords
Slide 19-

treatment Conservative Avoid misuse of voice Speech therapy / proper use of voice  No shouting / No whisper ? May change the profession Surgical  Microlaryngoscopy & LASER
