Watch the full video lecture on YouTube: https://www.youtube.com/watch?v=y4vxOBWcbok ## 👃 Clinical Case Discussion: Carcinoma of Maxilla Today, we'll have a clinical case discussion on a very important case: **Carcinoma of Maxilla**. This is a case that very commonly comes as a **long case** for postgraduates, with a large number of viva questions attached to it. We'll go through the patient's history and the questions arising from it, cover the clinical examination findings and their significance, summarize the case, arrive at a provisional diagnosis with staging, and outline the management plan. --- ### 👤 Patient Profile - **Age:** 55 years - **Sex:** Male - **Religion:** Hindu - **Occupation:** Carpenter - **Residence:** Bangalore ### 🗣️ Chief Complaints - **Bilateral nasal obstruction** since **2 months** - **Nasal discharge from the left side** since **1.5 months** - **Swelling in the left cheek** since **1 month** > What is the importance of Age in a case involving the nose? > What is the importance of Gender in a case involving the nose? > What is the importance of Occupation in a case involving the nose? > What does Hard wood dust VS Soft wood dust exposure lead to in a case of sinonasal malignancy? --- ### 📜 History of Present Illness **Bilateral Nasal Obstruction** - Patient was apparently asymptomatic **2 months back** - **Insidious onset**, initially involving only the **left side** - **Rapidly progressive** to involve the right side within the next **20 days** - Obstruction is **complete on the left** and **partial on the right** - **Continuous** throughout the day - No aggravating or relieving factors > When can you see Bilateral nasal obstruction in a case of CA Maxilla? > What does Gradually Progressive VS Rapidly Progressive indicate? **Left Sided Nasal Discharge** - Since **1.5 months** - **Insidious onset** - **Mucoid** in type - **Occasionally blood stained**, spontaneous - **Non foul smelling** - Continuous in nature - No aggravating or relieving factors > What are the causes of Blood stained Nasal discharge? > What does Unilateral Foul smelling, blood stained nasal discharge in children & adult indicate? **Swelling in the Left Cheek** - Since **1 month** - **Insidious onset**, **gradually progressive** to attain the current size - Associated with **numbness of the left cheek** - No aggravating or relieving factors > What is the Differential diagnosis of cheek swelling? > What does cheek numbness indicate? **Associated Complaints** - Mouth breathing - Snoring - Hyponasal speech > What does mouth breathing and snoring indicate in a case of CA Maxilla? > What is hyponasality of speech also known as? > State the differences between Rhinolalia Clausa VS Rhinolalia Aperta. --- ### ❌ Relevant Negative History (with Clinical Significance) ⭐ Negative history is not written as a separate heading in the case sheet.

--- ### 🩺 Local Examination #### Examination of the Nose **Inspection** - Facial asymmetry present - **Left nasolabial fold obliterated** - Skin normal - External osteocartilaginous framework normal - Bilateral ala and columella normal - **Left vestibule:** Mucoid discharge present - Right vestibule normal **Anterior Rhinoscopy** - Septum **deviated to the right side** - **Left side:** Pale, irregular mass filling the entire left nasal cavity, with **everted margins**, covered with mucoid discharge - On probing: **sensitive to touch, friable, bleeds on touch, firm in consistency** - **Probe can be passed all around except laterally** **Posterior Rhinoscopy** - Pale irregular mass seen in the **left choana** - Right choana free - Eustachian tube opening free on both sides - Posterior end of the septum free **Paranasal Sinuses** - All non-tender **Functional Tests** | Test | Finding | | --- | --- | | Cottle's test | No improvement on both sides | | Cold spatula test | Decreased misting on the right, absent misting on the left | | Cotton wool test | Reduced movement on the right, absent movement on the left | | Smell | Present on both sides | **Cranial Nerve Examination** - **Reduced sensation over the left cheek** - All other cranial nerves intact --- #### Examination of the Cheek **Inspection** - Diffuse swelling of the **left cheek** - Size: approximately **2 x 3 cm** - **Globular** in shape - **Ill-defined borders** - Skin over the swelling appears normal **Palpation** - Inspectory findings confirmed - Extent: - Vertically: 1 cm from the lower eyelid to 3 cm above the lower border of the mandible - Horizontally: from 5 cm from the tragus, continuing medially onto the lateral wall of the nose, blunting the nasolabial fold - Ill-defined borders - No local rise of temperature - No tenderness - **Hard in consistency** - **Skin free and pinchable** - **Swelling fixed to the underlying bone**, does not move independently of maxillary movement **Other Examinations** Eye, oral cavity, oropharynx, indirect laryngoscopy, ear and neck examination: **Normal** --- ### 🧠 Interpretation of Examination Findings #### Septum Deviated to the Right The mass has grown large enough to **push the septum across the midline**, explaining the bilateral nasal obstruction. #### Pale, Irregular Mass ⭐ **Irregularity** distinguishes a malignant from a benign mass. A benign mass such as a nasal polyp is described as **pale, glistening and smooth**. Disordered tissue growth in malignancy produces an **irregular surface**. #### Everted Margins A feature of **malignancy**. #### Covered with Mucoid Discharge Suggests **secondary obstructive changes**, where the tumour obstructs the sinus outflow tract causing secondary sinusitis. #### Sensitive to Touch The malignant lesion invades the underlying mucosa and its **sensory nerve supply**, producing pain on touch. ⭐ A polyp is **insensitive to touch**, as edematous hypertrophic mucosa has very few sensory nerve endings. #### Friable and Bleeds on Touch Due to **abnormal neovascularization** of tumour tissue. Tumour vessels are thin walled and lack normal supportive stroma, so they rupture with minimal trauma. > Name some conditions where it bleeds on touch on probing. #### Firm in Consistency Reflects the **solid cellular nature** of malignant tissue. ⭐ A polyp feels **soft and boggy**, being hypertrophic edematous mucosa. #### Probe Passes All Around Except Laterally Indicates the **point of origin or attachment** of the mass. 👉 The mass arises from the **lateral wall of the nose**, where the maxillary sinus opens into the middle meatus through its ostium. #### Posterior Rhinoscopy Findings | Finding | Interpretation | | --- | --- | | Mass in the left choana | Tumour spans the entire anteroposterior length of the nasal cavity | | Right choana free | Disease still confined unilaterally at the level of the choana; no septal crossing or bilateral posterior spread | | Eustachian tube opening free | No nasopharyngeal extension | | Posterior end of septum free | No posterior septal invasion | #### Cheek Swelling * **Diffuse swelling with ill-defined borders** and hard consistency suggests infiltration of the subcutaneous tissue from the maxillary sinus * **Skin free and pinchable** indicates the skin of the cheek is not involved, so the tumour is not T4 * **Fixed to underlying bone** indicates bony involvement --- ### 👁️ Importance of Examining Other Regions #### Eye Examination Looks for **proptosis**, diplopia and extraocular muscle involvement. ⭐ The **direction of proptosis** indicates the sinus of origin. > What is the direction of Proptosis in CA Maxilla VS CA Ethmoid? #### Oral Cavity & Oropharynx Extension of the tumour from the nasopharynx to the soft palate causes **restriction of soft palate movement**, lowering of the soft palate, or a mass hanging into the oral cavity. #### Indirect Laryngoscopy To rule out a **synchronous lesion** in the larynx. #### Ear Examination Nasopharyngeal extension blocks the **eustachian tube opening** in the lateral wall of the nasopharynx, impairing ventilation and drainage of the middle ear, leading to **serous otitis media**. #### Neck Examination Cervical lymph node involvement in sinonasal malignancy **upstages** the tumour and changes the treatment protocol. --- ### 📝 Case Summary - 55-year-old male, carpenter by occupation, chronic bidi smoker - Bilateral nasal obstruction for 2 months, initially left sided and rapidly progressive to the right within 20 days, complete on the left and partial on the right - Left sided nasal discharge for 1.5 months, mucoid, occasionally blood stained, non foul smelling - Left cheek swelling for 1 month, gradually progressive, with cheek numbness, mouth breathing, snoring and hyponasal speech - Anterior rhinoscopy: pale irregular mass filling the left nasal cavity with everted margins, sensitive to touch, friable, bleeds on touch, firm in consistency, probe passes all around except laterally - Posterior rhinoscopy: pale irregular mass in the left choana, rest free - Cheek swelling with ill-defined borders, hard in consistency, skin free and pinchable, fixed to underlying bone --- ### 🩺 Provisional Diagnosis **Left sided malignant growth of the maxilla**, Clinical stage: **T3N0MX (Stage III)** > What are the points in Favour of the Diagnosis? > What are the staging systems in CA Maxilla? > What is Ohngren’s line? > What is Ohngren’s Classification? > What is Lederman's Classification? > What are Horizontal Lines of Sebileau? > Is Suprastructure & Infrastructure the same in Ohngren & Lederman Classification? --- ### 📊 TNM Classification of Maxillary Sinus Carcinoma #### T Staging | Stage | Description | | --- | --- | | **TX** | Tumour cannot be assessed | | **Tis** | Carcinoma in situ | | **T1** | Tumour limited to the antral mucosa, with no bony erosion or destruction | | **T2** | Tumour causing bony erosion or destruction, including extension into the hard palate or middle meatus, **except** extension into the posterior wall of the maxillary sinus and pterygoid plates | | **T3** | Involvement of any of: posterior wall of maxillary sinus, subcutaneous tissue, floor or medial wall of orbit, pterygoid fossa, ethmoid sinus | | **T4a** | Moderately advanced local disease.
