Management of orbital complications in palatomaxillary reconstruction: A review of preemptive and corrective measures.

Head Neck 2020 Mar 13;42(3):556-568. Epub 2019 Dec 13.

THANC (Thyroid, Head and Neck Cancer) Foundation, New York, New York.

Background: Reconstruction of orbit-sparing palatomaxillary defects requires consideration of globe dystopia, orbital volume, eyelid position and function, and the nasolacrimal system to preserve and optimize vision, globe protection, and appearance. We describe the fundamentals of orbital and eyelid anatomy, common orbital complications related to palatomaxillary reconstruction, and preemptive and corrective surgical techniques to be utilized during and after globe-sparing palatomaxillary reconstruction.

Methods: We present a review of the literature supplemented by clinical case examples. Read More

[Intubation Systems in Lacrimal Drainage Surgery - a Current Overview].

Klin Monbl Augenheilkd 2020 Jan 26;237(1):20-28. Epub 2019 Nov 26.

Zentrum für Augenheilkunde, Universität zu Köln, Medizinische Fakultät und Uniklinik Köln, Köln.

The development of microendoscopes in lacrimal drainage surgery has led to the introduction of novel surgical procedures that maintain transcanicular anatomy, including a variety of lacrimal drainage intubation systems. Depending on the location and extent of the lacrimal duct stenosis, bicanaliculoanular, monocanalicular, monocanaliculonasal, bicanalicular, and bicanaliculonasal intubation techniques and systems, as well as a combination of these, may be used. For isolated intubation of the puncta lacrimalia, perforated punctum plugs may be used, while pure monocanalicular intubation can be performed using a Mini-Monoka. Read More

Extramucosal pyriplasty without stenting for management of pyriform aperture stenosis.

Eur Arch Otorhinolaryngol 2018 Jun 16;275(6):1469-1475. Epub 2018 Apr 16.

Department of Otolaryngology, Alexandria Faculty of Medicine, 4 Kafr Abdou street # 605, Alexandria, 21529, Egypt.

Purpose: The current management options of congenital pyriform aperture stenosis (CNPAS) are either conservative measures awaiting further growth of the bony nasal framework or surgical intervention that focuses on bone removal from the margin of the pyriform aperture (PA) without exposure of the nasolacrimal duct (NLD) followed by stenting. Recently, CT measurements of the nasal cavity in CNPAS have shed light that the site of maximal bony obstruction corresponds to the bony buttress encasing the NLD rather than the margin of the PA as initially thought. Herein, we present an extramucosal pyriplasty technique that can be used without stenting to enlarge the PA and achieve immediate and sustained relief of nasal obstruction. Read More

Co-localization of lymphoid aggregates and lymphatic networks in nose- (NALT) and lacrimal duct-associated lymphoid tissue (LDALT) of mice.

BMC Immunol 2018 01 25;19(1). Epub 2018 Jan 25.

Institute for Anatomy and Cell Biology, University Medical Hospital Göttingen, Kreuzbergring 36, D-37075, Göttingen, Germany.

Background: The lymphatic vascular pattern in the head of mice has rarely been studied, due to problems of sectioning and immunostaining of complex bony structures. Therefore, the association of head lymphoid tissues with the lymphatics has remained unknown although the mouse is the most often used species in immunology.

Results: Here, we studied the association of nasal and nasolacrimal duct lymphatics with lymphoid aggregates in 14-day-old and 2-month-old mice. Read More

Director and Consultant, Balaji Dental and Craniofacial Hospital, Chennai, Tamil Nadu, India.

Tessier facial clefts are among the rarest facial clefts reported in literature and many contradicting issues have always been rising over the management and surgical approaches involved during the craniofacial cleft repair. Among the craniofacial clefts Tessier no. 4 is an extremely rare facial anomaly, and there are very few evidence which clearly describe the surgical approaches and techniques. Read More

Adenoid cystic carcinoma of the lacrimal sac: case report.

Arq Bras Oftalmol 2016 Sep-Oct;79(5):333-335

Department of Ophthalmology, Costa del Sol Hospital, Marbella, Malaga, Spain.

Lacrimal sac tumors are rare with a clinical presentation that typically includes obstruction of the lacrimal drainage system and epiphora as the most frequent symptom. Cribriform adenoid cystic carcinoma (ACC) is the most common malignant epithelial tumor of the lacrimal gland and minor salivary glands; however, its occurrence in the lacrimal drainage apparatus is extremely rare. Given the rarity of ACC, definitive diagnosis is almost invariably late conferring a poor prognosis. Read More

Clinical significance of routine lacrimal sac biopsy during dacryocystorhinostomy: A comprehensive review of literature.

Bosn J Basic Med Sci 2017 Feb 21;17(1):1-8. Epub 2017 Feb 21.

Institute of Ophthalmology, Clinical Center of Montenegro, Podgorica, Montenegro.

The main purpose of this paper is to provide the information about the incidence and types of pathology of secondary acquired obstructions of the lacrimal excretory outflow system caused by primary lacrimal sac non-neoplastic and neoplastic lesions. After a thorough literature search, 17 case-control studies were found and selected, data were extracted and categorized, to evaluate specific lacrimal sac pathology mimicking inflammation. A total of 3865 histopathologically examined lacrimal sac wall biopsy specimens from 3662 patients, taken during dacryocystorhinostomy for clinically presumed primary chronic dacryocystitis, were analyzed.
