“…The value of these modalities in the diagnosis of diseases of the LDS has been the subject of numerous studies. It is generally accepted that the modern imaging technique of DS--DCG is the gold standard for outlining the in vivo anatomy, luminal profile, and pathology of the LDS [6]. A typical DS-DCG image with a 1024 × 1024 matrix has an in-plane spatial resolution of 250 µm [3].…”

Background: Asymmetric lacrimal flow occurs in females more than males. We hypothesised that the normal lacrimal drainage system (LDS) may show subtle left-right asymmetry in morphometry when imaged on dacryocystography (DCG). Materials and methods: We retrospectively reviewed 60 normal bilateral LDSs. Images were analysed for 7 parameters: (1) combined length of either the superior or inferior canaliculus plus common canaliculus, (2) angle of insertion of common canaliculus into lacrimal sac (LS), (3, 4) length and width of the LS, (5) length of the nasolacrimal duct (NLD), and (6, 7) width of proximal and distal NLD. We tested

“…Variations in the diameter of the NLD have been studied in bone specimens and by computerized tomography (CT) (Saxena, 1984;Groessl et al;Janssen et al;Shigeta et al;McCormick & Sloan, 2009;Fasina & Ogbole, 2013;Ramey et al, 2013;Takahashi et al, 2011Takahashi et al, , 2013Yong et al, 2014) Obstruction of the NLD can occur anywhere in its trajectory; however, previous studies with dacryocystography and dacryoendoscopy have determined that in two thirds of patients, the most common site of obstruction is the entrance to its bony portion (62-73 %), and this is not always considered in CT studies (Sasaki et al, 2005;Francisco et al, 2007). The morphology of the entrance to the NLD varies among individuals.…”

Sex and Age Morphometric Variations in Bony Nasolacrimal Duct and Fossa for Lacrimal Gland in Mexican Population

SUMMARY:Primary acquired nasolacrimal duct obstruction is greater in women over 40 years and has been associated with morphometric variations in the osseous nasolacrimal duct, which varies according to age and sex. The objective is to determine variations regarding sex and age of the nasolacrimal duct and osseous fossa for lacrimal gland. One hundred sixteen dry orbits from Mexican population were analyzed; subdivided into four groups based on age and sex. The length, transverse and anteroposterior diameters of the bone entrance of the nasolacrimal duct, and the length and width of the fossa for lacrimal gland were determined. Statistical tests were applied to determine the significance of the differences found between groups. The nasolacrimal duct in women had shorter length than men in both age groups. The entrance had a wider transverse diameter in women than men independently of age and its anteroposterior diameter was shorter in men under 40 years than over 40 years. The fossa for lacrimal gland was larger in women under 40 years than in men of same age group and women over 40 years old. The lower third of the was wider in women under 40 years than in women over 40 years. Our study confirms significant differences between sex and age groups in some of the morphometric measurements of bony nasolacrimal duct and fossa for lacrimal gland in Mexican population. Comparative studies with and without clinical illness are needed to clarify if the bony characteristics of those structures participate in the etiopathogenesis and distribution differences observed in sex, age and ethnicity of thisillness.

“…Epiphora constitutes one of the major and very common problems in all age groups [1]. Recent developments in ophthalmology, such as balloon dilatation, stent implantation, laser therapy and endoscopy of the lacrimal drainage system, raise the need for a detailed anatomical knowledge of this system.…”

“…However, the surgical production of an inferior meatal window facilitates the treatment and observation of lesions inside the sinus during and after surgery [8]. With these techniques, the only important anatomical features seen in the inferior nasal meatus are the opening of NLD and the lacrimal fold [1,2].…”
