BACKGROUND: This study aimed to compare the view into the maxillary sinus using the posterior translacrimal approach compared with grade 3 antrostomy. METHODS: Grade 3 antrostomy followed by a posterior translacrimal approach was performed on four cadavers. The maximum intramaxillary view was documented endoscopically guided by electromagnetic navigation. Representative screenshots were evaluated in a blinded manner by three independent sinus surgeons. In addition, a prospective investigation of specific complications in the post-operative course of consecutive patients was performed...

BACKGROUND: Chronic rhinosinusitis (CRS) is a downstream complication following radiotherapy or chemoradiation for nasopharyngeal carcinoma (NPC). Endoscopic sinus surgery (ESS) is an accepted therapy for medically refractory CRS, but its efficacy in addressing CRS symptoms in patients with previously irradiated NPC is unclear. METHODS: All patients at the Stanford Sinus Center with a history of radiation therapy or chemoradiation for NPC between 2006 and 2015 were reviewed...

BACKGROUND: Endoscopic medial maxillectomies (EMMs) are used to optimize exposure of the maxillary sinus and retromaxillary areas. Although in type D EMM (Sturmann-Canfield procedure) the anterior superior alveolar nerve (ASAN) is always at risk of injury, only 29% of patients complained of alveolar process and dental anesthesia. The purpose of this anatomical study is to assess the neural anastomotic network of the ASAN (ASAN-NAN) and describe different extensions of type D EMMs in a preclinical setting...

OBJECTIVES: The minimally invasive step-up approach for treatment of walled off necrosis (WON) involves drainage followed by later necrosectomy as needed, and is superior to primary surgical necrosectomy. Reported series of endoscopic transluminal necrosectomy include highly selected patients. We report outcomes of a large series of patients with WON managed by an algorithm based on an endoscopically centered step-up approach. METHODS: Consecutive patients with necrotizing pancreatitis from 2009 to 2014, with intervention only for infected or persistently symptomatic WON...

OBJECTIVE: Balloon Sinuplasty for the management of paranasal sinus inflammatory diseases was introduced in otolaryngology in 2005. Over the past decade, evidence strongly supports its safety and efficacy for the treatment of chronic rhinosinusitis (CRS) in adults. Because it requires no bone or tissue removal, this procedure could be suitable in children. We present our initial experience of its use for the treatment of CRS in children. MATERIALS AND METHODS: A prospective study was performed of 30 children with failed medical therapy, who were scheduled for surgery...

Impaired olfaction is associated with a volume decrease in the olfactory bulb as well as in the gray matter of cortical olfactory areas. On the other hand, restitution of an impaired olfaction results in a regain of volume in these regions. Studies investigating similar changes in the cerebral white matter are virtually not existent. The aim of this prospective study therefore was to investigate cerebral white matter using magnetic resonance diffusion tensor imaging (DTI). 31 patients (54±13years) with olfactory impairment (chronic rhinosinusitis) and planned functional endoscopic sinus surgery (FESS) were included...

OBJECTIVE: Medically refractory chronic rhinosinusitis (CRS) can be managed with appropriate continued medical therapy (CMT) or surgery followed by CMT. Patients who initially elect CMT and do not experience adequate symptom resolution may "cross over" to endoscopic sinus surgery (ESS). Our objective was to identify patient covariates associated with this subset of patients who elect this change in treatment modality. STUDY DESIGN: Retrospective analysis of a prospective, multi-center cohort of adult patients with CRS enrolled between March 2011 and June 2015 in academic, tertiary referral clinics...

INTRODUCTION: Osteomas of the paranasal sinuses are benign bone tumours that produce clinical signs depending on their size and location. In most reported cases large tumours are excised by an external approach or in conjunction with an endoscopic technique. Endoscopic treatment of such tumours is a huge challenge for the operator. OBJECTIVE: Determine the optimal surgical approach by analysing giant osteomas of the frontal and ethmoidal sinuses in the literature...

An approach for total maxillectomy with endoscopic transection of the pterygoid process via the contralateral maxillary sinus is described. In total maxillectomy, the resection of the pterygoid process of the sphenoid is a key step for successful resection. However, a conventional craniofacial approach requires extensive incision in the face, elevation of the lateral cheek flap. Even after elevation of the lateral cheek flap, visualization of this region is not good. An endoscopic approach through the contralateral maxillary sinus improved visualization of the pterygoid process, and osteotomy using a diamond-drilling bar was successfully performed...

Introduction  Pneumosinus dilatans (PSD) is a rare phenomenon involving the expansion of the paranasal sinuses, without bony destruction or a mass. Previously documented cases have demonstrated simple expansion of a solitary air cell. We present two unique cases of PSD in the presence of meningioma, in which complex new cells developed within the frontal sinus. One of the two patients developed associated sinus disease. Case 1  A 28-year-old man presented with facial pain. A computed tomography scan showed an abnormally enlarged, septated right frontal sinus, not present on childhood scans...

Posttraumatic facial pain is due to an injured nerve, most often a branch of the trigeminal nerve. While surgical approaches to injuries of the supraorbital, supratrochlear, infraorbital, and inferior alveolar nerves have been reported, an injury to the anterior superior alveolar nerve (ASAN) has not been reported. An algorithm is proposed for the diagnosis of injury to the ASAN versus the infraorbital nerve itself. A case is reported in which pain relief was achieved by dividing the ASAN within the maxillary sinus, leaving the proximal end exposed within the sinus at the level of the orbital floor...

BACKGROUND: Foreign bodies within the sinuses, orbit, and skull base (FBSOS) are rare; hence, diagnosis and management guidelines are lacking. Endoscopic sinus surgery (ESS) removal is preferred because of the less invasiveness and minimal morbidity. This study was designed to summarize clinical experience with ESS management of FBSOS. METHODS: We retrospectively reviewed clinical manifestations, imaging findings, treatment, and outcomes in consecutive patients with ESS removal of FBSOS between 2004 and 2015 at a tertiary academic medical center...

Paranasal sinus mucoceles are mucus-containing cystic structures with an epithelial lining that completely fills in the paranasal sinuses. Although they are benign in nature, they may result in the destruction of the surrounding bony structures over time. Clinical findings such as exophthalmia, visual impairment, and diplopia occur due to pressure of the fronto-ethmoidal mucocele on the orbita. Currently, the endoscopic intranasal approach is preferred in the treatment of paranasal sinus mucoceles due to its minimal morbidity and low recurrence rates...
