ENT

980nm and 1470nm diode lasers are widely used in ear-nose-throat, due to their tissue-specific absorption and minimally invasive properties. 

1. 980nm Diode Laser in ENT

-Advantage: High affinity for hemoglobin, enabling precise hemostasis and targeted treatment of vascular-rich tissues, with minimal damage to surrounding non-vascular structures.

- Key Application:

1. Nasal Cavity Treatments:

- Ablation of nasal hemangiomas and telangiectasias (e.g., hereditary hemorrhagic telangiectasia), stopping recurrent nasal bleeding via vascular coagulation.

- Reduction of inferior turbinate hypertrophy: Shrink vascularized turbinate tissue to improve nasal ventilation, avoiding excessive damage to mucosal function.

2. Throat & Laryngeal Treatments:

- Removal of small vocal cord polyps/nodules (especially vascular ones): Precisely cut lesions with real-time hemostasis, protecting vocal cord mucosal integrity.

- Treatment of chronic pharyngitis: Ablate hyperplastic lymphoid follicles on the posterior pharyngeal wall to relieve sore throat and foreign body sensation.

3. Ear Treatments:

- Management of external auditory canal (EAC) hemangiomas or vascular granulation tissue: Coagulate abnormal blood vessels to remove lesions without damaging EAC skin.

2. 1470nm Diode Laser in ENT

- Advantage: High absorption by water molecules (the main component of soft tissues), generating concentrated thermal effects for efficient tissue cutting, vaporization, and ablation—ideal for treating non-vascular or dense soft tissues.

- Key Application:

1. Nasal Cavity & Sinus Treatments:

- Endoscopic sinus surgery adjuvant: Remove hyperplastic sinus mucosa, polyps, or adhesions, with clear surgical fields and reduced postoperative edema.

- Treatment of nasal septum deviation (during correction): Reshape deviated cartilage/bone tissue with precise cutting, minimizing trauma to nasal septal mucosa.

2. Throat & Laryngeal Treatments:

- Resection of larger laryngeal papillomas or benign tumors: Vaporize tumor tissue layer by layer, reducing the risk of residual lesions and protecting laryngeal function.

- Relief of laryngeal stenosis: Ablate scar tissue in the laryngeal cavity to restore airway patency, with less postoperative scarring.

3. Ear Treatments:

- Removal of EAC cholesteatoma or keratin plugs: Vaporize abnormal keratinous tissue without damaging the underlying EAC bone, lowering the risk of infection recurrence.
