Skull Base Defect

A number of craniofacial and systemic malformations have been described in association with choanal atresia. We report a case of bilateral choanal atresia associated with congenital absence of the cribriform plate, crista galli, and perpendicular plate of the ethmoid bone. The anterior skull base defect was detected by using high-resolution computed tomography with three-dimensional reconstructions. The findings support the mesodermal flow theory of choanal atresia, in which there is excess migration of neural crest cells into the developing nasal septum and posterior choanae. This occurs at the expense of cells that would otherwise form the rest of the ethmoid complex. Clinical implications include the need for adequate preoperative imaging of the anterior skull base and consideration of potential intracranial complications during surgical repair.

Fluid Leak

Postoperative cerebrospinal fluid (CSF) rhinorrhea after septoplasty is a known entity resulting from errors in surgical technique and improper handling of the perpendicular plate of the ethmoid bone. When these occur, urgent management is necessary to prevent deleterious sequelae such as meningitis, intracranial abscess, and pneumocephalus. Encephaloceles are rare occurrences characterized by herniation of intracranial contents through a skull base defect that can predispose patients to CSF rhinorrhea. In this report, we present a case of CSF rhinorrhea occurring 2 weeks after septoplasty likely from manipulation of an occult anterior skull base encephalocele. To our knowledge, no previous similar case has been reported in the literature. Otolaryngologists should be aware of the possibility of occult encephaloceles while performing septoplasties because minimal manipulation of these entities may potentially result in postoperative CSF leakage.

The Relationship

Objective: To investigate the association of high septal deviation with the olfactory fossa depth and Gera angle. Methods: Fifty-four computed tomography scans of patients with high septal deviation were evaluated. The olfactory fossa depth and Gera angle were measured. The values of the deviated and nondeviated sides were compared. Results: No association between high septal deviation and the olfactory fossa depth and Gera angle was found. Conclusion: High septal deviation does not affect the olfactory fossa depth and Gera angle. In other words, the olfactory fossa depth and Gera angle have no association with the high septal deviation.
