Congenital dacryocele with large intranasal cyst: efficacy of cruciate marsupialization, adjunctive procedures, and outcomes.

PURPOSE: To evaluate the safety and efficacy of a new technique of medial wall cruciate marsupialization of large intranasal cysts associated with dacryocele and to evaluate the outcomes. METHODS: A prospective, interventional consecutive case series of 7 patients with large intranasal cysts were included in this study. All patients underwent endoscopic marsupialization by a single surgeon (MJA) using a new technique involving a medial wall cruciate incision. Patients were followed up for a minimum of 6 months and analyzed for the resolution of dacryocele and intranasal cysts and anatomical and functional success. RESULTS: The mean age at presentation was 5.9 weeks with a female preponderance (71.4%). All patients presented with a subcutaneous swelling in lacrimal sac region. Acute dacryocystitis was noted in 42.8% (3/7). Associated lacrimal anomalies were noted in 28.5% (2/7), and associated respiratory distress was noted in 57.1% (4/7) of the patients. At a mean follow up of 10.8 months, anatomical patency and resolution of intranasal cyst were achieved in all cases, and functional success was noted in all except 1 patient. CONCLUSIONS: Endoscopic evaluation of all dacryoceles is recommended. Medial wall cruciate marsupialization is a safe and effective modality in the management of large intranasal cysts. Early diagnosis and appropriate quick referral are likely to prevent acute dacryocystitis, progression of dacryocele, and may aid in better outcomes.

International assessment of inter- and intrarater reliability of the International Frontal Sinus Anatomy Classification system.

BACKGROUND: Inconsistencies in the nomenclature of structures of the frontal sinus have impeded the development of a validated "reference standard" classification system that surgeons can reliably agree upon. The International Frontal Sinus Anatomy Classification (IFAC) system was developed as a consensus document, based on expert opinion, attempting to address this issue. The purposes of this study are to: establish the reliability of the IFAC as a tool for classifying cells in the frontal recess among an international group of rhinologists; and improve communication and teaching of frontal endoscopic sinus surgery (ESS). METHODS: Forty-two computed tomography (CT) scans, each with a marked frontal cell, were reviewed by 15 international fellowship-trained rhinologists. Each marked cell was classified into 1 of 7 categories described in the IFAC, on 2 occasions separated by 2 weeks. Inter- and intrarater reliability were evaluated using Light's kappa (κ), the interclass correlation coefficient (ICC), and simple proportion of agreement. RESULTS: Interrater reliability showed pairwise κ values ranging from 0.7248 to 1.0, with a mean of 0.9162 (SD, 0.0537). The ICC was 0.98. Intrarater reliability showed κ values ranging from 0.8613 to 1.0, with a mean of 0.9407 (SD, 0.0376). The within-rater ICC was 0.98. CONCLUSION: Among a diverse sample of rhinologists (raters), there was substantial to almost perfect agreement between raters, and among individual raters at different timepoints. The IFAC is a reliable tool for classification of cells in the frontal sinus. Further outcome studies are still needed to determine the validity of the IFAC.
