Epiphora, or abnormal tearing, occurs because of the blockage in the lacrimal drainage system, which impairs normal tearing channeling into the nose. It is essential that with proper history and examination including syringing and probing, a correct diagnosis is made. Syringing and probing are performed only in congenital and acquired nasolacrimal duct obstruction (NLDO). Dacryocystorhinostomy (DCR) is a procedure performed for the treatment of tearing (epiphora) due to blockage of the nasolacrimal drainage system. Endoscopic dacryocystorhinostomy (E-DCR) using telescopes has gained a lot of momentum among otolaryngologists, since the outcomes are comparable to the external approach. Advances in surgical technique and a better understanding of the anatomy have resulted in improvements in outcomes. The anatomy of the lacrimal system will be discussed in detail including the surgical indications and techniques of DCR. The advantages, results, and complications of surgery will be highlighted.

Combining rhinoplasty and endoscopic sinus surgery (ESS) was first reported in 1991 by Sheman and Matarasso. Since then, many authors have documented a large series showing the overall efficacy of combining the two procedures. The focus of this manuscript is to document the author’s recent experience with combining rhinoplasty and endoscopic sinus surgery and highlight the changes that have occurred during the author’s 2-years experience. A retrospective data review was performed on 53 (31 females and 22 men, age range 16–55 years) patients who underwent combined rhinoplasty and ESS between January 2016 and December 2018 at Pantai Hospital Kuala Lumpur by the same surgeon. The mean age was 31.8 years. All patients had severe nasal obstruction with chronic rhinosinusitis and were followed up for a minimum of 6 months post-surgery and underwent ENT workup, which included history, office rigid endoscopy, CT scans of paranasal sinuses and preoperative photography. Initially, the ESS was performed followed by the open rhinoplasty with or without osteotomy. The ESS consisted of middle turbinate reduction [15/53 (28.3%)], maxillary antrostomy [36/53 (67.9%)], ethmoidectomy [38/53 (71.6%)], frontal sinusotomy [7/53 (13.2%)], and sphenoidotomy [9/53 (16.9%)]. Most of the sinus symptoms resolved postoperatively with 47 (88.6%) of 53 patients describing their improvement as significant. Fifty (94.3%) of 53 patients stated that they would recommend the concurrent procedure. The benefits of these advances are illustrated by a review of the literature with good results (functional and cosmetic) and minimal complications.

Anatomical variations of the sinuses are common and may lead to obstruction to the ventilation and drainage of the sinuses. This may lead to osteomeatal complex disease refractory to medications. A preoperative CT of the paranasal sinuses acts as road map guide to identify vital anatomical variations and its relationship to the orbit, skull base, neurological and vascular structures, to prevent iatrogenic injuries. To control intraoperative bleeding, it is critical to identify the anterior and posterior ethmoidal artery indentations and sphenopalatine artery in the anterior and lateral nasal walls. It is essential for the surgeon to familiarize with the anatomy of the ethmoid region, lateral nasal wall, sphenoid sinus, sella and parasellar region and pterygopalatine/infratemporal fossa before embarking on these approaches. The advent of CT scans and state-of-the-art FESS instrumentation has made surgery of the paranasal sinuses less of a mystery for the surgeon. Therefore, identifying and addressing these anatomical variations during FESS is crucial in restoring ventilation and drainage.

Laryngo-pharyngeal reflux (LPR); esophageal reflux; pharyngolaryngeal reflux; or reflux laryngitis refers to the backflow of acid from the stomach to the upper aerodigestive tract of the larynx and pharynx. Repetitive reflux of these contents may lead to LPR. It has been estimated that half of the otolaryngology patients with laryngeal and voice disorders have LPR. The pattern of reflux is different in LPR and gastroesophageal reflux. LPR usually occurs during the daytime in the upright position, whereas gastroesophageal reflux disease more often occurs in the supine position at nighttime or during sleep. Laryngeal edema is an important indicator of LPR that is most often neglected. LPR was previously deemed a controversial topic in laryngology but is now clearer with a better understanding of the pathogenesis. Diagnosis is made based on symptoms, and laryngoscopy aided with investigations and confirmed the response to treatment.
