Head and Neck Imaging
4
Feb

Overview

Head and neck imaging uses CT MRI and ultrasound depending on the indication. It evaluates tumors infections and trauma. Detailed anatomic imaging guides surgical planning.

Oncologic Imaging

Imaging stages head and neck cancers and assesses treatment response. PET CT is useful for metabolic assessment. MRI provides soft tissue detail for surgical planning.

Airway and Swallowing

Fluoroscopy and video swallow studies assess swallowing function. Imaging evaluates airway patency and structural abnormalities. Findings guide therapy and surgical decisions.

Vascular Considerations

CT angiography and MR angiography assess vascular lesions and fistulas. Vascular imaging is important in trauma and tumor planning. Endovascular options may be guided by imaging findings.

Imaging for Sleep Apnea Surgical Planning
4
Feb

Overview

Imaging identifies anatomic contributors to airway obstruction for surgical planning. CT MRI and dynamic imaging techniques assess soft tissue and skeletal factors. Imaging complements endoscopic evaluation for comprehensive planning.

Maxillomandibular Advancement Planning

CT and 3D imaging guide osteotomy planning and implant positioning for advancement procedures. Imaging predicts airway enlargement and surgical impact. Precise imaging improves surgical outcomes and reduces complications.

Upper Airway Soft Tissue Procedures

MRI and CT evaluate tongue base tonsillar and soft palate anatomy for targeted surgery. Dynamic imaging during simulated sleep may reveal collapse patterns. Imaging informs selection of procedures and expected benefit.

Outcome Assessment

Postoperative imaging documents structural changes and device position when applicable. Imaging combined with polysomnography assesses treatment efficacy. Long term follow up integrates imaging with clinical outcomes.

Bronchial Tree

Feb

Overview

The bronchial tree conducts air from the trachea to bronchioles and alveoli with progressive branching that increases surface area. Cartilaginous support in larger airways maintains patency while smaller airways rely on smooth muscle tone. Airway clearance and mucociliary function protect against infection.

Trachea and Main Bronchi

The trachea bifurcates into right and left main bronchi at the carina and further divides into lobar and segmental bronchi. Structural lesions compression or foreign bodies affect airflow and require imaging or endoscopic evaluation. Bronchoscopy provides direct visualization and intervention.

Small Airways

Bronchioles lack cartilage and are susceptible to constriction inflammation and obstruction in diseases such as asthma and bronchiolitis. Small airway disease contributes to airflow limitation and ventilation heterogeneity. High resolution CT assesses small airway pathology.

Clinical Relevance

Airway diseases include obstruction infection bronchiectasis and neoplasms. Imaging and endoscopy guide diagnosis and therapeutic interventions such as stenting or resection. Pulmonary rehabilitation and pharmacotherapy improve airway function.

Respiratory System

Feb

Overview

The respiratory system enables gas exchange between the environment and the bloodstream. It includes the nose pharynx larynx trachea bronchi and lungs with alveolar units. Ventilation perfusion matching is critical for oxygenation and carbon dioxide removal.

Upper Airway

The nose and pharynx filter warm and humidify inspired air. The larynx protects the airway and facilitates phonation. Upper airway patency affects breathing and sleep related disorders.

Lower Airway and Lungs

The trachea divides into bronchi and bronchioles terminating in alveoli for gas exchange. Pulmonary circulation delivers blood for oxygenation and removes carbon dioxide. Surfactant and alveolar architecture maintain lung compliance and surface area.

Clinical Relevance

Respiratory diseases include pneumonia COPD asthma and pulmonary embolism. Imaging such as chest radiography CT and ultrasound aid diagnosis and guide therapy. Pulmonary function testing complements imaging for functional assessment.

Anesthesiology

Feb

Overview

Anesthesiology provides intraoperative anesthesia care perioperative optimization and acute pain management. Services include regional anesthesia critical care and airway expertise.

Preoperative Assessment

Anesthesia teams evaluate comorbidities medication management and risk stratification to optimize patients before surgery. Clear communication reduces perioperative complications.

Intraoperative Care

Anesthesiologists manage physiologic stability airway control and anesthetic depth using monitoring and pharmacologic strategies tailored to surgical needs.

Postoperative Pain and Recovery

Acute pain services provide multimodal analgesia regional blocks and opioid stewardship to enhance recovery and reduce adverse effects.
