INTRODUCTION Endoscopic sinus surgery can result in serious extraocular muscle dysfunction. The medial rectus muscle is more frequently affected than other extraocular muscles. METHODS A transconjunctival subperiosteal medial orbitotomy was successful in retrieving a partially extirpated medial rectus muscle after endoscopic sinus surgery. RESULTS A previous attempt to localize this muscle ...

Background and Objectives: External dacryocystorhinostomy (DCR) is the method of choice to treat nasolacrimal duct (NLD) obstruction and the other approaches are compared with it, with a failure rate of 4% to 13%. The current study aimed to assess the causes of failure in external DCR by postoperative endoscopic and pathological evaluation. <stro...

This article is divided into six sections that are related to six commonly used operations for surgery on the maxillary sinus. The authors discuss maxillary sinoscopy, the Caldwell-Luc procedure, extended middle meatus antrostomy, endoscopic maxillary sinus antrostomy, minimally invasive sinus technique, and balloon sinus procedures. In each of these procedures, the authors discuss potential co...

BACKGROUND Chronic rhinosinusitis has a major impact on the quality of life of patients with cystic fibrosis (CF) and may contribute to progression of chronic lung disease. Despite multiple sinus surgeries, maxillary sinus involvement is a recurrent problem. The modified endoscopic medial maxillectomy (MEMM) permits debridement in the clinic, improves mucus clearance with nasal irrigations, an...

INTRODUCTION Endoscopic techniques have been used extensively for the treatment of sinonasal skull base defects and resulting cerebrospinal fluid (CSF) leaks. Endoscopic surgery allows for improved visualization, high success rates, reduced morbidity, and shorter hospital stays. Most ethmoid and sphenoid skull base defects can be repaired endoscopically, but endoscopic repair of frontal sinus d...

This case series describes an alternative approach for removing ectopically erupted tooth in the maxillary sinus using improved endoscopic known as modified endoscopic-assisted surgery (MESS). We reviewed medical charts and radiographs of patients who underwent surgical removal ectopic MESS. The technique consisted creating a bony window wall with pre-adapted microplate, which was repositioned ...

Abstract Objective The extent of surgery, the type device used and head position may influence nasal irrigation. aim this study was to determine effectiveness topical irrigant delivery paranasal sinuses according these factors. Method Four cadaveric heads underwent four stepwise endoscopic dissections. Irrigations were evaluated after every stage using different devices (squeeze-bottle, gravity...
