Vomer Agenesis as a Rare Cause of Hypernasality
Hypernasality which is rare symptom commonly occur as a consequence of velopharyngeal insufficiency (VPI). VPI usually manifested as nasal air emission and hypernasal resonance during speech. The cause can be divided into congenital, neuromuscular disorder and surgical complication. Congenital cause of VPI includes cleft palate, nasal septum malformation such as vomer agenesis, submucous cleft palate and velar dysplasia, while neuromuscular VPI can be due to cerebral palsy or cerebrovascular accident. Surgical cause of VPI could be due to adenoidectomy and scarring of the velum post palatoplasty in cleft palate repair. We present a 17-year-old man who was diagnosed of congenital left nasolacrimal duct obstruction referred to us for left endoscopic dacrocystorhinostomy in which during nasoendoscopic examination revealed absence of vomer.
