Review of olfactory cleft roof anatomy.

Progress in skull-base endoscopic surgery has improved our knowledge of olfactory cleft (OC) anatomy. This article presents a review of current knowledge concerning the OC roof: descriptive anatomy, radiological exploration, and endoscopic observation. The OC is a narrow area in the most superior part of the nasal cavity. Its roof is the thinnest structure separating the nasal cavities from the brain; it comprises three superimposed tissues: nasal mucosa, ethmoid cribriform plate (ECP), and dura mater. The ECP comprises the anterior ECP containing the ethmoidal slit (ES) medially and the cribroethmoidal foramen (CEF) laterally; and the posterior ECP, comprising the olfactory foramina. The OC roof is bordered anteriorly by the nasal bone roof, laterally by the lateral ethmoid masses, and posteriorly by the jugum and anterior wall of the sphenoid sinuses. Imaging is crucial for analyzing this wall, providing precise detailed information on conformation and anatomic relations with adjacent structures such as the anterior ethmoidal artery. Understanding OC roof anatomy and correct interpretation of imaging are essential for safety in present-day functional endoscopic sinus surgery and anterior skull-base oncologic surgery.

How to identify the anterior cribriform plate in the medial approach to the frontal sinus.

Draf III frontal sinusotomy is one of the most complex surgical procedures on the frontal sinus, designed to limit the risks of restenosis by ensuring unification of the two ostia and resection of the floor of the sinus. This procedure requires a good knowledge of anatomy and sufficient surgical expertise to avoid the risk of CSF leak and to limit the risk of restenosis. The surgeon can use various landmarks, consisting of foramina, bone grooves and arteries located on the anterior part of the cribriform plate to guide the procedure. The purpose of this technical note is to explain the use of these landmarks to ensure safe Draf III frontal sinusotomy via a medial approach.

Impact of head and neck cancer on partner's sociability.

INTRODUCTION: "Sociability" is defined as the range of experiences linking the subject to others. This is the first study to focus specifically on the impact of head and neck cancer on the sociability of patients' partners. METHOD: Data were collected via a dedicated questionnaire sent to patients' partners. The main endpoint was partner's self-assessment of the impact of the patient's disease on the partner's everyday life. The impact on sociability was analyzed with respect to: the circle of friends (friendship environment), unknown environment, known outside environment, necessary environment, and solitary activities. RESULTS: Two hundred and seventy partners responded. Their everyday activities were impacted by the patient's disease in 71.5% of cases. The friendship environment was badly affected in 46.4% of cases. The unknown environment was affected in 44.0% of cases. Social practices related to the known outside environment were affected in 67.8% of cases, and the necessary environment in 26.0%; the number of solitary activities increased in 35.6% of cases. Social impact on patients' partners was thus considerable.
