We report on a patient who underwent maxillectomy and subsequent coronoid-temporalis flap reconstruction of the surgical defect to treat a maxillary sinus carcinoma invading the middle skull base. The patient underwent successful reconstruction of the middle skull base and displayed acceptable functional result. Middle skull base defects can be successfully repaired using a local coronoid-temporalis pedicled flap. The coronoid process of the mandible is advantageous as a local flap because it is close to the skull base defects and can easily be dissected from adjacent tissues. The use of a coronoid-temporalis pedicled flap offers excellent results without the need for further extensive surgery.

To describe the distribution of jugular bulb position and pneumatization of posterior lip of internal auditory meatus (IAM) in patients with vestibular schwannoma (VS). This retrospective study included 43 patients who had a thin slice (< 2 mm) CT temporal bone for preoperative planning of retrosigmoid approach for excision of VS between March 2011 and March 2021. On computed tomography (CT), high riding jugular bulb was defined by its relationship to IAM and correlated with type of jugular bulb according to Manjila et al.

Rationale: Smoking has been shown to be associated with circulating deficiencies in 25(OH)D3 and reduced sinonasal tissue levels of the active form of vitamin D, 1,25(OH)2D3. Given vitamin D's ability to reduce inflammation, we sought to examine if intranasal (IN) delivery of calcitriol [clinical analog of 1,25(OH)2D3] could reduce inflammation and improve disease severity in a murine model of chronic cigarette smoke-induced sinonasal inflammation (CS-SI).
Methods: Mice were exposed to CS 5 h/day, 5 days/week for 9 months, and then began IN calcitriol three times per week for 4 weeks.
