Objectives/Hypothesis:
To characterize the anatomic distribution of lymphatic malformations of the upper airway.
Study Design:
Case series with chart review.
Setting:
Tertiary care referral center specializing in the diagnosis and treatment of vascular anomalies.
Methods:
A 7-year (2004-2011) retrospective chart review of patients with lymphatic malformations was performed at a tertiary care referral center. Patients with airway lymphatic malformations were identified. The anatomic distribution of lymphatic malformations within the airway was reviewed.
Results:
A total of 141 patients with lymphatic malformations of the upper aerodigestive tract (UADT) were studied. Of these, 15 (11%) had laryngeal (supraglottic) involvement. In all of these patients, the disease was above the true vocal folds. Seventy-four (52%) patients had involvement of 1 anatomic zone (most common was the oral cavity), and 67 (48%) had involvement of multiple zones. With regard to each zone, 105 (75%) patients had involvement of the oral cavity, 50 (36%) the oropharynx, 8 (6%) the hypopharynx, 42 (30%) the parapharynx, and 12 (9%) had retropharygeal disease (some patients had multiple zones involved). No patients were identified with glottic, subglottic, or tracheal involvement.
Conclusions:
Based on our large series, airway involvement in head and neck lymphatic malformations may occur at multiple sites above the glottis. A high percentage of these patients have involvement of the oral cavity (75%) and oropharynx (35%). None involve the glottis, subglottis, or trachea.

Development of the Lymphatic System
The first lymph sacs to form are the paired jugular lymph sacs located at the junction of the internal jugular and subclavian veins. From these sacs, lymphatic capillary plexuses extend to the thorax, upper limbs, neck, and head, eventually forming lymphatic vessels. Each jugular lymph sac maintains a...
Lymphatic Vessels and Lymph Transport
This one-way system allows fluids, solutes, and even pathogens to enter but prevents their return to the intercellular spaces.
Lymphoid Cells and Tissues
Lymphoid cells consist of various types of immune system cells. These include B and T lymphocytes, which are responsible for producing antibodies and killing infected cells, respectively. Dendritic cells act as messengers between the innate and adaptive...

Secondary Lymphoid Organs
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...
