Watch the full video lecture on YouTube: https://www.youtube.com/watch?v=H6symZ9r6JI ### ๐ŸŒฌ What is Atrophic Rhinitis? Atrophic Rhinitis is a **chronic inflammatory condition of the nose** characterized by: - Progressive **atrophy** (wasting away) of the **nasal mucosa** and the **underlying turbinate bones**. - Leading to the formation of **greenish-yellow crusts**. - Resulting in abnormally **roomy nasal cavities**. - Associated with a very characteristic **foul-smelling odor**. #### ๐Ÿ“ **Key Features:** - Starts around **puberty**. - Tends to **regress** around middle age (>40 years). - More common in **females** than males. --- ### โœจ Types and Etiology of Atrophic Rhinitis Atrophic Rhinitis is classified into two types based on the cause: 1. **Primary Atrophic Rhinitis:** The underlying exact cause is **unknown**. 2. **Secondary Atrophic Rhinitis:** Develops as a result of another **specific underlying cause**. ### ๐Ÿฆ  Theories for Primary Atrophic Rhinitis: Various theories have been proposed. [*Mnemonic:* **HERNIAS**] - **H**ereditary - **E**ndocrinal - **R**acial - **N**utritional - **I**nfective - **A**utoimmune - **S**urfactant Deficiency >๐Ÿ“˜ In my detailed notes, Iโ€™ve discussed in detail each of these theories. #### **Subtypes of Primary Atrophic Rhinitis** (Based on Histology): - **Type 1:** Shows endarteritis and periarteritis. Benefits from estrogen therapy (vasodilation). - **Type 2:** Shows vasodilatation of capillaries. Estrogen therapy may worsen. ### ๐Ÿฅ Causes of Secondary Atrophic Rhinitis: Develops secondary to another cause. >What are the causes of Secondary Atrophic rhinitis? --- ### ๐Ÿ”ฌ Histology of Atrophic Rhinitis Examining nasal tissue reveals characteristic changes: - **Epithelial Changes:** Normal ciliated columnar epithelium with goblet cells is replaced by **stratified squamous epithelium**, and **cilia are lost**. - **Glandular Atrophy:** Atrophy of seromucinous glands. - **Nerve Atrophy:** Atrophy of nerve elements. - **Vascular Changes:** **Obliterative endarteritis and periarteritis** in arteries of mucosa, periosteum, and bone (prominent in Type 1). - Bone Resorption - Sinus Hypoplasia --- ### ๐Ÿ“‹ Clinical Features of Atrophic Rhinitis #### **Symptoms:** - Foul Smell (Halitosis) >What is Merciful Anosmia? - Anosmia >What are the reasons behind Anosmia in Atrophic Rhinitis? - Nasal Obstruction >What are the reasons behind nasal obstruction in Atrophic Rhinitis? - Epistaxis - Thick Greenish yellow Crusts and Discharge - Foreign Body Sensation - Slavic Facies >What is Slavic Facies? - Myiasis - Impairment of Hearing #### **Signs (On Examination):** - **General:** Foul smell emanating from the patient. - **Anterior Rhinoscopy:** - Nasal cavity full of **greenish or grayish-black dry crusts** covering turbinates and septum. - Bleeding on crust removal. - After cleaning, nasal cavities are **very roomy**. - Atrophy of **turbinate bones** (especially inferior and middle). Severe atrophy may allow visualization of the posterior nasopharyngeal wall. - Nasal mucosa is pale. - Septal perforation may be present. - In extreme cases, **saddle nose deformity**. - **Pharynx/Larynx:** May show similar atrophic changes (atrophic pharyngitis, laryngeal sicca). --- ### ๐Ÿ”ฌ Investigations of Atrophic Rhinitis - **CT Scan of Nose & Paranasal Sinuses** >What are CT Scan findings in Atrophic Rhinitis? - **Nasal Swab:** Culture & sensitivity (to identify secondary invaders). - **Nasal Biopsy:** Confirms diagnosis by histology (epithelial/vascular changes, glandular/nerve atrophy). - **Investigations for Secondary Causes:** - Chest X-ray, Sputum for AFB, Mantoux test (TB). - Serological tests (Syphilis, other granulomatous diseases). - Tests for Rhinoscleroma (complement fixation, biopsy). - Tests for SLE (urine/serum protein). --- ### ๐Ÿ’Š Complications of Atrophic Rhinitis Atrophic rhinitis, if left untreated, can lead to several troublesome and even socially debilitating complications. Some key complications include: - Nasal deformities like saddle nose - Septal perforation - Foul-smelling crusts and secondary infections - Psychological distress due to social embarrassment > ๐Ÿ‘‰ _**There are several more clinically significant complications โ€” including ones that affect the ears, lungs, and quality of life โ€” all covered in detail in my ENT notes.**_ --- ### ๐Ÿฅ Management of Atrophic Rhinitis There is no specific cure for **primary** atrophic rhinitis. Management aims to control symptoms, improve hydration and hygiene, and minimize crusting/odor. #### **Medical Treatment:** - **Nasal Irrigation & Crust Removal:** **Most important step**. 2-3 times/day initially, reduced later. - **Alkaline Nasal Douching** - Buffered Hypertonic Saline. >What is the composition of Alkaline Nasal Douching? >What is the role of each component in Alkaline Nasal Douching? - **Application of 25% Glucose in Glycerine:** Paint the nasal cavity. >What is the amount of Glucose and Glycerine used? >What is the role of Glucose and Glycerine here? - Kemicetine Anti-Ozena Solution - Estradiol Spray - Submucosal injection of Placental Extract - Oral Potassium Iodide - Systemic Streptomycin >What is the dosage of Streptomycin in Atrophic Rhintis? #### **Surgical Management:** Aims to reduce the size of the roomy nasal cavities to improve airflow pattern and moistening, and sometimes reroute salivary ducts. - **Young's Operation** - **Modified Young's Operation** - **Nasal Cavity Narrowing Procedures** - Reduce chamber size. - Lautenslager Operation - Wilson's Operation - Submucosal/Subperiosteal Implants under floor/lateral wall/septum mucosa. - Plastipore Implantation. >What is Lautenslager operation? >What is Wilson's Operation? >What implants are used reducing the size of nasal cavity in Atrophic Rhinitis? - **Wittmack Operation** - **Stellate Ganglion Block** - **Vestibuloplasty** >What is Young's operation & Modified Young's Operation? >What are the advantages & disadvantages of Young's operation & Modified Young's Operation? >What is Wittmack Operation? >How does Stellate ganglion block help in Atrophic Rhinitis? >What is Vestibuloplasty? --- ### ๐Ÿค” Differential Diagnosis of Atrophic Rhinitis When a patient presents with symptoms suggestive of Atrophic Rhinitis (crusting, odor, obstruction), consider: - Nasal or Paranasal Sinus Tumor. - Purulent Rhinitis or Sinusitis. - Nasal Diphtheria. - Tuberculosis of the Nose. - Gumma (Syphilis). - Intranasal Foreign Body. - Nasal Cholesteatoma (rare). --- ### Prognosis of Atrophic Rhinitis Atrophic Rhinitis persists for many years, typically starting around puberty. However, there is often **spontaneous recovery** or significant improvement around **middle age (>40 years)**. --- ## About This Note This note on Atrophic Rhinitis is one of the free ENT study notes published by The ENT Resident.
