R Lenzi, L Muscatello
We have read the article by Green et al.(1) with great interest, given the results from their review, the recommendation of performing a mucosal sparing technique when performing dacryocystorhinostomy seems logical. However, based on our experience we would like to make some comments on this subject. This article is protected by copyright. All rights reserved.

PURPOSE: Patients with pituitary adenomas often present with visual deficits. While the aim of endoscopic endonasal transsphenoidal surgery (EETS) is to improve these deficits, permanent worsening is a possible outcome. The aim of this meta-analysis was to evaluate the effect of EETS for pituitary adenomas on visual outcomes. METHODS: A meta-analysis was conducted according to the PRISMA guidelines. Pooled prevalence was calculated for complete recovery, improvement, and deterioration of visual field deficits, visual acuity and unspecified visual function in fixed- and random-effect models, including assessment of heterogeneity (I(2)) and publication bias (Begg's test)...

BACKGROUND: Orthostatic headache (OH) is a potential complication of lumbar drainage (LD) usage. The incidence and risk factors for OH with the use of lumbar drainage during endoscopic endonasal procedures have not been documented. OBJECTIVE: To investigate the incidence of post-procedure OHs associated with placement of LD in patients undergoing endoscopic endonasal procedures. METHODS: We prospectively noted the placement of LDs in a consecutive series of endoscopic endonasal skull base surgeries...

The nasal cavity and paranasal sinuses are covered with ciliated respiratory mucosa of ectodermal origin, known as Schneiderian epithelium, which can give rise to different types of sinonasal carcinomas. A 42-year-old woman with a history of nasal polypectomy 3 years previously presented with nasal obstruction and rhinorrhea. She was found to have a papillary mass involving the left nasal cavity, and the left maxillary and ethmoidal sinuses by radiologic examination. She underwent endonasal resection under the diagnosis of oncocytic papilloma...

We conducted a prospective interventional study to evaluate the role of endoscopic endonasal dacryocystorhinostomy in children. Our study population was made up of 20 patients-18 boys and 2 girls, aged 2 to 12 years (mean: 5.3)-who presented with signs and symptoms suggestive of nasolacrimal duct blockage that was refractory to conventional medical treatment. In all cases, blockage was confirmed by nasolacrimal duct syringing that demonstrated regurgitation from the opposite punctum. The primary outcome measures for success were resolution of symptoms and duct patency on lacrimal irrigation...

The objective of the present work was to study topographical and anatomical relationships between the lacrimal passages and the walls of the nasal cavity from the standpoint of the rhinosurgeon. The materials for the study were obtained by examining 15 corpses. It was found out that in 91% of the cases, the natural ostium of the maxillary sinus is localized within 11.6 cm from the lacrimal tubercle. In 62% of the cases, the nasolacrimal passage opens in the region of the vault of the inferior nasal passage as an orifice roughly 0...

Rocco Severino, Paolo Severino
Frontal sinus mucoceles are benign, pseudocystic lesion deriving from the obliteration of the sinus ostium, resulting in a continuous mucous accumulation. The growing process of a mucocele leads to a progressive enlargement of the sinus cavity, thickening and eroding its bony walls up to invading the surrounding tissues. The surgical procedure through an endoscopic endonasal approach is the current treatment option for such conditions, but in cases with an extensive bone erosion and intracranial or intraorbital extension, a transcranial approach should be preferred...

BACKGROUND: Resection of clivus chordomas through extensive skull base approaches is associated with high mortality and morbidity even in experienced hands. We report our experience with endoscopic trans-sphenoidal surgery, or a "wait-and-scan" strategy in selected patients. METHOD: Ten patients were diagnosed with clivus chordomas during an 8-year period. Six patients underwent primary treatment with endoscopic trans-sphenoidal surgery, followed by adjuvant proton-beam therapy in three of these patients...

The authors present 4 cases in which they used intraoperative CT (iCT) scanning to provide real-time image guidance during endonasal odontoid resection. While intraoperative CT has previously been used as a confirmatory test after resection, to the authors' knowledge this is the first time it has been used to provide real-time image guidance during endonasal odontoid resection. The operating room setup, as well as the advantages and pitfalls of this approach, are discussed. A mobile intraoperative CT scanner was used in conjunction with real-time craniospinal neuronavigation in 4 patients who underwent endoscopic endonasal odontoidectomy for basilar invagination...

BACKGROUND: Having one hand occupied with the endoscope is the major disadvantage for the surgeon when it comes to functional endoscopic sinus surgery (FESS). Only the other hand is free to use the surgical instruments. Tiredness or frequent instrument changes can thus lead to shaky endoscopic images. METHODS: We collected the pose data (position and orientation) of the rigid 0° endoscope and all the instruments used in 16 FESS procedures with manual endoscope guidance as well as robot-assisted endoscope guidance...

The endoscopic, endonasal transcribriform approach (EETA) is an important technique used to directly access the anterior skull base and is increasingly being used in the management of olfactory groove meningiomas (OGMs). As this approach requires removal of the cribriform plate and olfactory epithelium en route to the tumor, patients are anosmic postoperatively. Here, we report the development of phantosmia and dysgeusia in two patients who underwent EETAs for OGMs, which has not yet been reported in the literature...
