Q: Which among the following is not used in post laryngectomy rehabilitation?

Tracheostomy tube. ***Tracheostomy tube*** - Following total laryngectomy, the **trachea is permanently diverted** to form a permanent stoma in the neck for breathing. - In the context of **post-laryngectomy rehabilitation**, the focus is on **voice restoration** methods rather than airway management devices. - While laryngectomy tubes or stoma buttons may be used temporarily for **stoma care** (preventing stenosis, maintaining patency), traditional **tracheostomy tubes are not part of voice rehabilitation** protocols. - The patient breathes directly through the permanent stoma, and rehabilitation centers on restoring communication ability. *Esophageal speech* - **Esophageal speech** is a voice rehabilitation method where air is injected into the esophagus and then expelled, vibrating the pharyngoesophageal segment to produce sound. - It requires no external devices, only extensive training, and can provide functional voice for communication. - This is one of the **three main voice restoration options** after laryngectomy. *Tracheoesophageal puncture* - **Tracheoesophageal puncture (TEP)** with voice prosthesis is the **gold standard** for voice rehabilitation post-laryngectomy. - A small fistula is created between trachea and esophagus, and a one-way valve (voice prosthesis) is inserted. - Air from the lungs is diverted through the prosthesis into the esophagus, vibrating the pharyngoesophageal segment to produce speech. - Provides the **most natural-sounding voice** among rehabilitation options. *Electrolarynx* - An **electrolarynx** is an external, battery-operated device held against the neck or placed intraorally that generates vibrations. - The vibrations are articulated by the mouth and tongue to produce speech. - Provides **immediate communication** post-laryngectomy, though the voice quality is mechanical or robotic.

Q: A patient presents with vertigo, tinnitus, and head tilt. He underwent myringoplasty for the safe type of chronic suppurative otitis media (CSOM) 6 months back. What is your diagnosis?

Perilymphatic fistula. ***Perilymphatic fistula*** - The combination of **vertigo**, **tinnitus**, and **head tilt** occurring after a **myringoplasty**, even for a safe type of CSOM, suggests a perilymphatic fistula. - Myringoplasty can occasionally involve trauma to the **oval or round window**, leading to a direct communication between the inner ear (perilymph) and the middle ear, causing these symptoms. *Paget disease* - This is a **bone remodeling disorder** that primarily affects the skull, pelvis, and long bones, leading to bone pain and deformities. - While it can cause hearing loss (due to otosclerosis) and a sense of imbalance, it does not typically present with the acute onset of **vertigo** and **tinnitus** following ear surgery. *Labyrinthitis* - **Labyrinthitis** is an inflammation of the inner ear, typically caused by a viral infection, leading to sudden, severe **vertigo**, **nausea**, and often **hearing loss** or **tinnitus**. - While the symptoms of vertigo and tinnitus are present, the history of recent myringoplasty makes a **structural compromise** like a perilymphatic fistula a more specific diagnosis than generalized inflammation. *Vestibular schwannoma* - Also known as an acoustic neuroma, this is a **benign tumor** on the eighth cranial nerve, causing **gradual unilateral hearing loss**, **tinnitus**, and **imbalance**, but rarely sudden, intense vertigo unless very large. - The presentation with a history of myringoplasty and acute symptoms makes a **spontaneous structural defect** more likely than a slowly growing tumor.

Q: A 12-year-old presented with fever and difficulty swallowing. He had swelling in the marked region and was advised to undergo tonsillectomy. Post-surgery the gauze continued to soak with blood. Which of the following vessels must have been injured?

Paratonsillar vein. ***Paratonsillar vein*** - The **paratonsillar vein**, also known as the **external palatine vein**, is the major vein draining the palatine tonsil and usually the primary source of **post-tonsillectomy hemorrhage**. - Its superficial location and tendency to be large and thin-walled make it particularly vulnerable to injury during **tonsillectomy**, leading to persistent bleeding. *Ascending pharyngeal artery* - The ascending pharyngeal artery contributes to the blood supply of the tonsil, but it is a **deep-seated artery** that is less frequently injured during tonsillectomy compared to the paratonsillar vein. - While its injury could lead to significant bleeding, it's not the most common vascular source of hemorrhage in this context. *Tonsillar branch of facial artery* - The **tonsillar branch of the facial artery** is a significant arterial supply to the tonsil. However, arterial bleeding is typically more pulsatile and rapid, whereas persistent soaking of gauze suggests venous bleeding. - While injury to this artery can occur, the **paratonsillar vein** is a more common source of persistent oozing hemorrhage post-tonsillectomy. *Retromandibular vein* - The **retromandibular vein** is located posterior to the mandible and is not directly associated with the tonsillar bed. - Injury to this vein during a **tonsillectomy** is highly unlikely due to its anatomical position.
