“…The mean lacrimal canal width measured in this study was 9.56, and the data in this study were significantly different in comparison to those in previous studies Lock et al, 1 14.06 AE 3.46 mm and Janssen et al, 23 6.81 mm AE 1.30 mm. Since there was not a sufficient number of studies in the literature regarding the advantages and disadvantages of lacrimal canal width in terms of PLRA, a larger study may be conducted to investigate the relationship between lacrimal canal dimension and PLRA.…”

“…This medially displaced mucosa is placed back after surgery, with excellent cosmetic healing of the mucosal edges and without disrupting the function of the nasolacrimal canal. 1 The frequency and anatomic variations of the PLR have also been investigated in previous studies. These previous studies of anatomy and frequency have reported different results.…”

Background The prelacrimal recess approach, is frequently preferred in creating a minimally invasive surgical corridors. Objective The aim of this study was to evaluate the Prelacrimal recess (PLR) anatomy using Cone Beam Computed Tomography in patients with Maxillary Sinus Hypoplasia. Methods The paranasal Cone Beam Computed Tomography series of 84 adults were analyzed retrospectively. The antero-posterior and mesio-distal widths of the PLR and the antero-posterior width of the naso-lacrimal duct were measured. The patients were divided into three groups according to the antero-posterior width of PLR to evaluate the feasibility of prelacrimal recess approach as Type 1 (0-3 mm), Type 2 (>3–7 mm) and Type 3 (>7 mm). Results The mean antero-posterior width of PLR was 3.11 ± 1.49mm in the patients and 4.77 ± 1.76 mm in the controls. The mean mesio-distal width of PLR was 7.64 ± 1.49 mm in the patients and 3.17 ± 2.05 mm in the controls. The mean antero-posterior width of naso-lacrimal duct was 9.58 ± 2.80 mm in the patients and 9.46 ± 2.42 mm in the controls. Conclusions The width of the antero-posterior PLR in patients with Maxillary Sinus Hypoplasia was found to be significantly lower in comparison to individuals with normal maxillary sinuses in the measurements performed on paranasal Cone Beam Computed Tomography scans. Hence, while planning a Functional Endoscopic Sinus Surgery with prelacrimal recess approach for maxillary sinus, the anatomical structure of the naso-sinusoidal region should be carefully analyzed, and individual anatomical variations such as Maxillary Sinus Hypoplasia should not be ignored.

“…This percentage appeared to be higher (93 per cent) in Chinese subjects in a study published by Lock et al . 8 (including 100 sinus CT scans with 200 sides), who reported that the feasibility of the prelacrimal recess approach in Chinese subjects was 93 per cent.…”

Objective This study aimed to assess the outcomes of a prelacrimal recess approach assisted middle meatal antrostomy in the management of hard to reach maxillary sinus pathologies. Method Twenty-five patients with maxillary sinus pathology underwent prelacrimal recess approach assisted middle meatal antrostomy (with a prelacrimal recess width of more than 3 mm). Patients were prospectively evaluated using both the Arabic version of the Sino-Nasal Outcome Test-22 and nasal endoscopy at least 6 months post-operatively. Results Our study included 25 maxillary sinuses (13 with antrochoanal polyps, 10 with maxillary fungal ball and 2 with a migrated part of a tooth). At a mean follow-up period of 10.9 months, all patients showed significant improvement in total mean Sino-Nasal Outcome Test-22 score. There was recurrence of one case with antrochoanal polyp and two cases with asymptomatic synechia. Injury to the nasolacrimal duct was not reported. Conclusion A prelacrimal recess approach assisted middle meatal antrostomy is a reliable and safe technique to manage pathologies in hard to reach regions within the maxillary sinus.
