Vocal cord nodule
Vocal nodules, also known as singer's nodes or screamer's nodes, are benign growths that develop on the vocal cords due to vocal trauma from prolonged periods of speaking at unnatural low tones or high intensities. They most commonly affect teachers, actors, vendors, pop singers, and school-going children who are too assertive and talkative. Pathologically, vocal abuse or misuse causes edema, hemorrhaging, and fibrosis in the vocal cord tissue, forming hardened nodules on the free edge of the vocal cords at their point of maximum vibration. Patients experience hoarseness of voice, vocal fatigue, and neck pain with prolonged phonation. Treatment involves voice therapy and re-education for mild cases

It describes various inflammatory disorders of the vocal cords such as arytenoid granuloma which presents with hoarseness and can be caused by mechanical trauma, intubation, or gastroesophageal reflux. It also discusses benign structural lesions including vocal cord polyps, nodules, and pseudocysts. Treatment options covered include voice therapy, surgery, and treating underlying causes.
E.N.T 5th year, 5th lecture (Dr. Hiwa)
Vocal cord nodules, polyps, and Reinke's edema are common laryngeal lesions caused by phonotrauma or repetitive vocal trauma. Vocal cord nodules appear as small, whitish lesions at the junction of the anterior and posterior vocal folds. Treatment involves speech therapy and possible microlaryngoscopy or laser excision. Vocal cord polyps are usually unilateral and pedunculated lesions located on the vocal folds. Treatment is surgical excision to confirm diagnosis and prevent recurrence. Reinke's edema causes diffuse swelling of the vocal folds and is associated with smoking. Treatment involves smoking cessation and possible surgery.
Physiology of hearing & approach to hearing loss in a child
The document provides an overview of the anatomy and physiology of the human ear. It discusses the outer, middle and inner ear. The outer ear includes the pinna and ear canal. The middle ear contains the tympanic membrane, ossicles and eustachian tube. The inner ear houses the cochlea which contains hair cells that transduce sound into neural signals via the auditory nerve. The document also describes different types of hearing loss including conductive, sensorineural and mixed, and approaches to assessing hearing loss in children.
EMBRYOLOGY AND MALFORMATION OF EAR
The document discusses congenital anomalies of the external ear. It begins by describing the normal development of the ear in utero from weeks 6 to month 5. It then discusses various types of anomalies including microtia (underdeveloped ear), macrotia (overly large ear), and anomalies of the external acoustic meatus such as atresia (blockage of the ear canal). It provides details on the classification, causes, and reconstructive options for microtia. It also discusses other rare anomalies such as anotia (complete absence of the ear), dysplastic ears, low-set ears, ear tags, and ear canal anomalies. Syndromes commonly associated with ear anomalies like Treacher Collins and Goldenhar syndrome are
voice dis orders lec.pptx
Speech is the vocalized form of human communication that involves articulation using the mouth, voice produced by vocal cords, and fluency or rhythm of speech. Speech production requires respiration from the lungs, phonation by the vocal cords, and articulation using structures in the mouth and nose. Hoarseness or roughness of voice can be caused by issues with the vocal cords such as paralysis, tumors, or nodules that prevent normal vibration. Various types of dysphonia including adductor, abductor, and mixed can be diagnosed and treated through laryngoscopy, botulinum toxin injections, voice therapy, and other methods.
Benign lesions of larynx
This document discusses several benign lesions of the larynx including vocal nodules, vocal polyps, Reinke's edema, contact ulcers, intubation granulomas, leukoplakia, ductal and saccular cysts, juvenile and adult papillomas, chondromas, and haemangiomas. It provides descriptions of their causes, symptoms, clinical signs, investigations, and treatment options which typically involve voice therapy, medical management, or surgical excision depending on the specific lesion.
Benign tumours of larynx
This document discusses various non-neoplastic and neoplastic tumors of the vocal cords. It describes vocal cord nodules as localized epithelial lesions caused by voice misuse or abuse. Reinke's edema is the collection of fluid in the vocal cord subepithelial space, often due to smoking or vocal abuse. Leukoplakia is a precancerous white plaque on the vocal cords. Juvenile papillomatosis is a recurrent benign tumor caused by HPV that mostly affects children under age 4 and can involve the larynx, trachea and bronchi. Chondromas are benign tumors arising from the laryngeal cartilage that usually affect men ages 40-60.
Vocal cord nodule
Vocal cord nodules are symmetric, mid-vocal fold lesions that occur due to physical stresses on the vocal folds from heavy voice use. They cause hoarseness by impairing vocal fold closure and vibration during voicing. Nodules appear in pairs and resemble mounds of tissue protruding from the vocal folds. While voice rest and steroids can reduce swelling, voice therapy is the primary treatment to develop healthier voice use techniques. Surgery may be considered in severe, longstanding cases not improving with therapy. Nodules require ongoing management rather than a one-time "fix" and do not necessarily end a singing career if properly treated.
Hearrrrrrrr
The document describes the anatomy and physiology of the human ear, including the outer, middle, and inner ear. It discusses how sound is transmitted through the ear canal to the eardrum and ossicles of the middle ear, then into the cochlea of the inner ear where vibrations are transduced into nerve impulses. Common ear disorders like conductive hearing loss, sensorineural hearing loss, Meniere's disease, and otitis media are outlined along with their symptoms and treatments, which include hearing aids and cochlear implants.
Vocal cord nodules and its homeopathic treatment
Vocal cord nodules are benign growths on the vocal cords that cause hoarseness, breathiness, and other voice problems. They develop from overuse of the voice through activities like singing, shouting, or smoking. Common symptoms include hoarseness, low pitch, pain, and fatigue. Treatment may involve biopsy and homeopathic remedies to address the whole constitution, as nodules can sometimes develop into cancer if underlying genetic and lifestyle factors aren't addressed.
Tumours of the larynx
This includes benign lesions including vocal nodules and laryngocele. It includes benign and malignant tumours.
Chronic Otitis Media Effusion
Chronic otitis media effusion, also known as chronic middle ear fluid, is a condition characterized by the long-term presence of fluid in the middle ear. The middle ear is the space behind the eardrum that contains the tiny bones responsible for transmitting sound vibrations to the inner ear
Paediatric voice disorders

Breast cancer: Post menopausal endocrine therapy
Breast cancer in postmenopausal women with hormone receptor-positive (HR+) status is a common and complex condition that necessitates a multifaceted approach to management. HR+ breast cancer means that the cancer cells grow in response to hormones such as estrogen and progesterone. This subtype is prevalent among postmenopausal women and typically exhibits a more indolent course compared to other forms of breast cancer, which allows for a variety of treatment options.
Diagnosis and Staging
The diagnosis of HR+ breast cancer begins with clinical evaluation, imaging, and biopsy. Imaging modalities such as mammography, ultrasound, and MRI help in assessing the extent of the disease. Histopathological examination and immunohistochemical staining of the biopsy sample confirm the diagnosis and hormone receptor status by identifying the presence of estrogen receptors (ER) and progesterone receptors (PR) on the tumor cells.
Staging involves determining the size of the tumor (T), the involvement of regional lymph nodes (N), and the presence of distant metastasis (M). The American Joint Committee on Cancer (AJCC) staging system is commonly used. Accurate staging is critical as it guides treatment decisions.
Treatment Options
Endocrine Therapy
Endocrine therapy is the cornerstone of treatment for HR+ breast cancer in postmenopausal women. The primary goal is to reduce the levels of estrogen or block its effects on cancer cells. Commonly used agents include:
Selective Estrogen Receptor Modulators (SERMs): Tamoxifen is a SERM that binds to estrogen receptors, blocking estrogen from stimulating breast cancer cells. It is effective but may have side effects such as increased risk of endometrial cancer and thromboembolic events.
Aromatase Inhibitors (AIs): These drugs, including anastrozole, letrozole, and exemestane, lower estrogen levels by inhibiting the aromatase enzyme, which converts androgens to estrogen in peripheral tissues. AIs are generally preferred in postmenopausal women due to their efficacy and safety profile compared to tamoxifen.
Selective Estrogen Receptor Downregulators (SERDs): Fulvestrant is a SERD that degrades estrogen receptors and is used in cases where resistance to other endocrine therapies develops.
Combination Therapies
Combining endocrine therapy with other treatments enhances efficacy. Examples include:
Endocrine Therapy with CDK4/6 Inhibitors: Palbociclib, ribociclib, and abemaciclib are CDK4/6 inhibitors that, when combined with endocrine therapy, significantly improve progression-free survival in advanced HR+ breast cancer.
Endocrine Therapy with mTOR Inhibitors: Everolimus, an mTOR inhibitor, can be added to endocrine therapy for patients who have developed resistance to aromatase inhibitors.
Chemotherapy
Chemotherapy is generally reserved for patients with high-risk features, such as large tumor size, high-grade histology, or extensive lymph node involvement. Regimens often include anthracyclines and taxanes.
