Bilateral Simultaneous Endoscopic Dacryocystorhinostomy: Outcome and Impact on the Quality of Life of the Patients.

Int Arch Otorhinolaryngol 2019 Apr 15;23(2):191-195. Epub 2019 Feb 15.

Ear Nose and Throat Department, Head and Neck and Skull Base Center, King Abdullah Medical City (KAMC-HC), KSA, Makkah, Saudi Arabia.

 Bilateral simultaneous endoscopic dacryocystorhinostomy (endo-DCR) has received little attention in the literature, thus many surgeons continue to address bilateral nasolacrimal duct obstruction at two stages, rather than in the same setting.  To evaluate the feasibility and the outcome of simultaneous bilateral Endo-DCR and its impact on the quality of life of the patients.  We have conducted a retrospective analysis of patients who underwent bilateral simultaneous endo-DCR between March 2013 and February 2017 at our tertiary care institution.

Sinonasal (Schneiderian) papilloma of the lacrimal sac.

Proc (Bayl Univ Med Cent) 2019 Jan 16;32(1):121-123. Epub 2019 Jan 16.

Department of Otolaryngology, Baylor Scott & White-Temple/Texas A&M UniversityTempleTexas.

Sinonasal papillomas, also known as Schneiderian papillomas, are benign but infiltrative epithelial neoplasms that arise from ectodermally derived pseudostratified ciliated (or Schneiderian) epithelium that lines the sinonasal tract and nasal cavity. We describe a rare case of a sinonasal papilloma confined to the lacrimal duct and sac in a 45-year-old man who presented with 10 months of right-sided epiphora and swelling of his medial right lower eyelid. He was found to have a 10 × 10 mm area of distension near the right lacrimal sac and underwent an external dacryocystorhinostomy. Read More

Prolactin and Prolactin-inducible protein (PIP) in the pathogenesis of primary acquired nasolacrimal duct obstruction (PANDO).

Med Hypotheses 2019 Apr 1;125:137-138. Epub 2019 Mar 1.

Institute of Functional and Clinical Anatomy, Friedrich-Alexander-University Erlangen-Núrnberg, Germany.

Primary acquired nasolacrimal duct obstruction (PANDO) is a syndrome of unknown etiology, predominantly affecting post-menopausal females, characterized by progressive inflammation, fibrosis and subsequent obstruction of the nasolacrimal duct. Numerous factors have been proposed as possible etiologic factors and include anatomical configuration, ocular and nasal infections, peri-lacrimal vascular disorders, hormonal influence, lacrimal drainage lymphoid tissue, gastroesophageal reflux disease, topical medications, swimming pool exposure, smoking, genetic factors, autonomic and lysosomal dysregulation. The authors hypothesize Prolactin (PRL) and Prolactin-inducible protein (PIP) play a role in the etiopathogenesis of primary acquired nasolacrimal duct obstruction. Read More

Various modifications of a vascularized nasoseptal flap for repair of extensive skull base dural defects.

J Neurosurg 2019 Feb 8:1-9. Epub 2019 Feb 8.

OBJECTIVEEndonasal surgery of the skull base requires watertight reconstruction of the skull base that can seal the dural defect to prevent postoperative CSF rhinorrhea and consequent intracranial complications. Although the incidence of CSF leakage has decreased significantly since the introduction in 2006 of the vascularized nasoseptal flap (the Hadad-Bassagasteguy flap), reconstruction of extensive skull base dural defects remains challenging. The authors describe a new, modified vascularized nasoseptal flap for reconstruction of extensive skull base dural defects. Read More
