Fibrous nasal dysplasia
Fibrous (normal bone and marrow tissue is replaced with fibrous tissue) nasal (nose ) dysplasia (abnormal tissue), is a skeletal disorder affecting bone forming cells. In this disorder, the normal bone cells fail to mature and produce too much fibrous or connective tissue.
Frontonasal dysplasia is the result of the abnormal development of the head and face in utero. Individuals with frontonasal dysplasia may present with occular hypertelorism (hyper = too much, telorism – increased distance between two organs), incomplete formation of the front of the skull, and/or cleft of the nose/upper lip/palate.
A deviated septum is the misalignment of the nasal cartilage that divides the nasal passages. A deviated septum may result in reduced airflow and possible difficulty with breathing.
Nasal airway obstruction
Nasal airway obstruction may be secondary to multiple issues including; disease (including nasal masses), anatomical disorder (including deviated septum, large turbinates, nasal valve disorder). Nasal airway obstruction may impact breathing.
