“…The nasolacrimal ducts have 12 to 18 mm of extension and are responsible for draining tears to the inferior nasal meatus. 2 Treating traumatic injuries involving fractures of the maxillofacial and orbital regions is already a recurrent practice for oral and maxillofacial surgeons. Most patients with these lesions have epiphora, recurrent episodes of conjunctivitis, and mucoceles due to lacrimal sac and/or nasolacrimal duct involvement.…”

Objectives: To evaluate the anatomy of the nasolacrimal duct and the adjacent maxillary bone thickness using multislice computed tomography. Methods: Tomographic images of 92 individuals (184 sides) were analyzed according to sex, side, and sagittal (Class I, II, and III) and vertical (mesocephalic, brachycephalic, and dolichocephalic) skeletal patterns. The largest diameters of the nasolacrimal duct and the thickness of the adjacent maxillary bone were measured when the lacrimomaxillary suture was completely visible. In addition, the measurements were performed 2 mm above and below the midpoint. The maxillary bone and nasolacrimal duct measurements were analyzed by one-way ANOVA with Tukey’s post-hoc test. Results: Females had a significantly narrower lacrimal duct at the midpoint (p=0.026) and 2 mm above it (p=0.025). Maxillary bone thickness was greater in Class II individuals compared to Class I at the midpoint (p=0.012) and 2 mm above it (p=0.027). The dolichocephalic group had greater maxillary bone thickness at the midpoint (p=0.014) and 2 mm below it (p=0.005) compared to the brachycephalic group. Maxillary bone thickness was greater in mesocephalic individuals compared to dolichocephalic individuals (p=0.04). Conclusions: Brachycephalic Class I individuals have lower maxillary bone thickness adjacent to the nasolacrimal duct, which increases the risk of injury during the bone fixation process.

Imaging in Disorders of the Lacrimal Drainage SystemVarious imaging modalities have been described for the anatomical and functional assessment of the lacrimal drainage system. Computed tomography (CT) and computed tomographic dacryocystography (CT DCG) are the most useful investigations. There are other investigations for the functional integrity of the lacrimal drainage system. This chapter presents an overview of all available modalities with special emphasis on CT DCG. The available modalities described in the literature include computed tomography, computed tomographic dacryocystography, ultrasound, magnetic resonance imaging, magnetic resonance dacryocystography, scintigraphy and digital subtraction dacryocystography [1][2][3][4][5].Although in complex situations like posttraumatic NLD obstruction imaging of the lacrimal system is often indicated [6] but in primary acquired nasolacrimal duct obstruction (PANDO), radiological investigations are generally not advised. This is because the diagnosis can often be reached through a battery of clinical tests including regurgitation test, probing syringing and the fluorescein dye test [7,8]. However, in certain selective cases of PANDO (mentioned below), radiological evaluation must be done to avoid failures. CT DCG is a widely used imaging modality and is considered a gold standard method for the evaluation of the lacrimal drainage system [9,10].
