Background Access to the anterior, lateral, inferior, and inferomedial maxillary sinus has been a limitation of the middle meatal antrostomy. Expanded techniques such as the modified medial maxillectomy provide access to many of these areas but require remucosalization, and crusting can occur during the recovery phase. The prelacrimal approach (PLA) offers direct 0° endoscope access to these areas. Additionally, PLA can preserve the nasolacrimal duct and mucosal coverage. Objectives We describe the current surgical technique and outcomes of PLA patients. Methods Consecutive adult patients with pathology addressed by PLA to the maxillary sinus were assessed. The primary outcome was the restoration of the lateral wall, and the secondary outcomes were early (< 90 days) and late morbidity (> 90 days). Results Forty patients (52.8 ± 17 years, 62.5% female) were assessed. All patients had successful restoration of the lateral nasal wall (100% [95CI: 91.2%-100%]). The complications reported were primarily dysesthesia (early 10% and late 2.5%). Conclusion The PLA provides robust access to the anterior, lateral, inferior, and inferomedial maxilla. PLA offers rapid mucosal recovery while preserving the normal physiology and the lacrimal systems with low morbidity.
Background Middle meatal antrostomy (MMA) is the traditional intervention for chronic maxillary sinusitis but often fails to correct a nonfunctioning maxillary sinus that has lost its capability for mucociliary clearance. Endoscopic-modified medial maxillectomy (EMMM) can reshape the maxillary sinus and avoid a “sumping” effect, preventing secondary bacterial colonization, encouraging dependent drainage, and promoting effective nasal irrigation. Objectives We describe a modification of the EMMM surgical technique in patients with recalcitrant maxillary sinusitis and perioperative outcomes. Methods Consecutive adult patients with nonfunctioning maxillary sinuses managed with EMMM were assessed. Primary outcomes were the resolution of the presenting symptom and the absence of mucostasis. Secondary outcomes were early (<90 days) and late (>90 days) morbidity. Results Fifty-seven patients (51.7 ± 17.5 years, 56.1% female) were assessed. Fifty-two patients had complete resolution of their presenting symptom (91.2% [95% CI: 80.7–97.1]) and 52 patients had an absence of mucostasis (91.2% [95% CI: 80.7–97.1]). Those with persistent crusting were also those with symptoms. Early morbidities included temporary dysesthesia (3.2%), bleeding (1.1%), and pain (3.2%), with no late morbidities. Conclusion EMMM is a robust approach for salvaging a nonfunctioning maxillary sinus. The procedure enhances nasal irrigation, supplants mucociliary clearance, and discourages dependent mucus retention.
The incidence of otosclerosis in nonendemic patients is low, and preoperative diagnosis can be challenging. The aim of this study was to evaluate computed tomography (CT) findings in patients with otosclerosis and determine their correlation with audiometric findings and surgical outcome in a nonendemic population. We retrospectively reviewed 17 patients from August 2011 to August 2013 with surgically confirmed otosclerosis who underwent preoperative high-resolution CT scans and pre- and postoperative audiometry. Otosclerotic foci were identified on the scans. The density ratio of these foci was calculated and compared with pre- and postoperative audiometric parameters. One patient with Paget disease was excluded from the study. A total of 19 ears were operated on and included in the data analysis. CT scans were normal in 4 ears (21.1%). Hypodense lesions were detected in the remaining 15 (78.9%) ears and the region of interest mapped out. The density ratio was obtained between the hypodense area and adjacent normal labyrinthine bone. No statistically significant correlation was found between the density ratio and any of the audiometric parameters tested (p > 0.05). The diagnosis of otosclerosis in nonendemic areas is challenging. A preoperative CT scan can be useful when otosclerotic foci are present. However, the density ratio of the otosclerotic foci did not correlate with audiometric parameters or surgical outcome.
