BACKGROUND: The endoscopic modified Lothrop procedure (EMLP) is commonly performed in recalcitrant frontal sinusitis, in part to achieve better penetration of medicated irrigations postoperatively. Although EMLP requires a septectomy for exposure, it is unknown whether septectomy size affects delivery of irrigations. In this study we evaluated the role of septectomy in delivery of irrigations to the EMLP cavity. METHODS: EMLP was performed on fresh human cadavers with sequentially increasing septectomy (minimal septectomy: drilling across septum to combine frontal sinuses; standard septectomy: 1...

Objectives  The use of nasopharyngeal landmarks to localize the petrous apex has not been previously described. We describe a purely endoscopic endonasal corridor to localize the petrous apex without transgressing any of the paranasal sinuses. Methods  Anatomical dissections of four formalin preserved cadaveric heads (eight petrous apices) were performed to evaluate the feasibility of a nonsinus-based approach and illustrate the surgical landmarks and measurements that are useful for surgery in this area...

BACKGROUND: Addressing anterior maxillary sinus pathology endoscopically that is inaccessible with an endoscopic modified medial maxillectomy requires either a prelacrimal approach (PLA) or an endoscopic Denker's approach (EDA). The PLA involves removing the medial wall of the prelacrimal recess (PLR), which is the bone between the pyriform aperture (PA) and nasolacrimal duct (NLD), from nasal floor to orbital floor. The PLA preserves the inferior turbinate and NLD, whereas both are sacrificed during an EDA...

BACKGROUND: Isolated polypoid changes of the middle turbinate were recently reported as having a high association with inhalant allergy. A more advanced manifestation of this association may present as polypoid changes of the entire central sinonasal compartment (i.e., the middle and superior turbinates, and the posterosuperior nasal septum), while the lateral sinus mucosa remains relatively normal. OBJECTIVE: To introduce and describe this newly recognized variant of chronic rhinosinusitis (CRS), termed central compartment atopic disease (CCAD)...

Objective To define relationships between the frontal sinus opening, ostia of other frontal recess cells, and endoscopic landmarks and to develop a clinically useful framework to guide frontal sinus surgery. Study Design Retrospective review. Setting Tertiary care academic referral center. Methods Adult patients with computed tomography (CT) without sinonasal pathology were included. Virtual endoscopy (using OsiriX) and corresponding CT reconstructions were used to identify all visible ostia in the frontal recess and characterize their positions in spaces between the uncinate/agger nasi (U), bulla ethmoidalis (EB), and middle turbinate (MT)...

Several minimally invasive modifications of endoscopic medial maxillectomy have been proposed recently, with the least traumatic techniques utilizing the lacrimal recess as a route to enter the sinus. The aim of the study was to analyze the anatomy of medial maxillary wall in the region of nasolacrimal canal and, thus, to determine the capability of performing minimally invasive approach to the maxillary sinus leading through the lacrimal recess. The course of nasolacrimal canal and the distance between the anterior maxillary wall and the nasolacrimal canal (the width of lacrimal recess) were evaluated in 125 randomly selected computed tomography (CT) head examinations...

The objectives of this study are to evaluate the occurrence of postoperative middle turbinate lateralization and the relationship between this lateralization and the risk of iatrogenic sinusitis after endoscopic transnasal sphenoidotomy procedure. Patients who undergone endoscopic transnasal sphenoidotomy and came under the surveillance of our otorhinolaryngology department between the January of 2010 and the December of 2015 were retrospectively scanned. Among them, the patients who were evaluated with paranasal sinus computed tomography (CT) postoperatively were included in the study...

Propel and Propel Mini sinus implants are mometasone furoate-coated bioabsorbable stents used as an adjunct in the management of chronic rhinosinusitis after endoscopic sinus surgery. The original sinus implant was deployed in the ethmoid sinuses to provide medialization of the middle turbinate, decrease scarring and mucosal adhesions, limit polyp regrowth, and reduce mucosal inflammation. A structurally smaller version of the Propel, the Propel Mini, was developed and now has been approved for endoscopic placement in the frontal sinuses...

It is necessary for the surgeon to be familiar with frontal recess anatomy during an endoscopic approach to the frontal sinuses. The aim of this study was to evaluate the prevalence of frontal recess cells in Japanese adults as well as the association between the frontal recess and the location of the anterior ethmoidal artery (AEA). The frontal recess cells and the AEAs were retrospectively evaluated in CT scans of the nasal and paranasal sinuses for 89 patients. The prevalence of agger nasi cells was 90.7%...

BACKGROUND AND PURPOSE: Inferior turbinate hypertrophy and concha bullosa often occur opposite the direction of nasal septal deviation. The objective of this retrospective study was to determine whether a concha bullosa impacts inferior turbinate hypertrophy in patients who have nasal septal deviation. MATERIALS AND METHODS: The electronic medical record was used to identify sinus CT scans exhibiting nasal septal deviation for 100 adult subjects without and 100 subjects with unilateral middle turbinate concha bullosa...

Endoscopic endonasal dacryocystorhinostomy (DCR), when compared to external techniques, has always had guarded acceptance primarily due to inconsistent success rates. The most common cause of surgical failure in endoscopic DCR is very high/very low mucosal incision, obstruction of neo-ostium by granulation tissue, infolding of flap or formation of synechiae between middle turbinate and the neo-ostium site post-operatively. Several techniques and modifications have been suggested by various authors over the years since the first introduction of endoscopic endonasal DCR...

A vascularized middle turbinate flap (MTF) might be useful in the repair of lesions in the anterior olfactory groove. The sizes of the MTF and inferior turbinate flap (ITF) and these distances up to the frontal base were analyzed by computed tomography (CT) using a picture archiving and communication system (PACS) in 20 patients. The minimum flap measurement to reconstruct the skull base was defined as the distance from the basal plate to the medial slope or lateral slope edge of the MTF and the ITF on the coronal view...

Multiple anatomical variants were encountered during a cone beam computed tomography (CBCT) study of the nasal cavity of a 43-year-old male patient. These were mostly related to the nasal turbinates, suggestive for an unusual development of ethmoturbinals. Pneumatized turbinates were observed: bilateral supreme, superior, and middle concha bullosa. There were bilateral paradoxically curved superior turbinates, as well as a unilateral paradoxically curved inferior turbinate. There was also found a unilateral accessory middle turbinate, presenting as a medially bent uncinate process...

BACKGROUND: External dacryocystorhinostomy (DCR) is at present the gold standard for the surgical treatment of acquired nasolacrimal duct obstructions, but tremendous progress has been made in recent years in improving minimally invasive techniques, sparing not only the skin, but also the medial lid structures, which contribute to the physiological palpebral-canalicular pump mechanism. The purpose of this study is to report our 1-year experience with the surgical technique, complications and results of transcanalicular laser assisted DCR...

A 43-year-old female presented with persistent nasal congestion with intermittent epistaxis without resolution for the preceding 5 years. Clinical examination revealed a large pink rubbery mass, medial to the middle turbinate in the right nasal cavity extending to the choana. Radiographic images demonstrated a heterogeneously enhancing lobular soft tissue mass filling the right nasal cavity, causing lateral bowing of the right medial orbital wall and extending posteriorly to the right anterior ethmoid sinus...

A 50-year-old female presented with a slowly enlarging painless mass of the right medial canthus. The past surgical history is significant for external dacryocystorhinostomy for acquired nasolacrimal duct obstruction 10 years prior and subsequent endoscopic and external revisions. Imaging revealed a large fronto-ethmoidal sinus mucocele extending into the right medial orbit. On surgical exploration, the right middle turbinate was found to have lateralized, obstructing sinus outflow. The mucocele was evacuated and ethmoidectomy and middle turbinectomy were performed...
