Conductive hearing loss

Reduced transmission through the external or middle ear that requires interpretation alongside cochlear function and the actual hearing-test limitations.

Sensorineural hearing loss

A hearing deficit involving cochlear or neural mechanisms, characterized using appropriate testing rather than inferred from a single symptom.

Carhart notch

An apparent bone-conduction threshold change associated with altered ossicular mechanics, classically assessed around two kilohertz in stapes fixation.

Tympanometry

Measurement of middle-ear acoustic behavior across pressure changes, useful for assessing mechanics but not a direct test of cochlear function.

Cholesteatoma

A keratinizing epithelial process in an abnormal middle-ear or temporal-bone location that can erode structures and cause important complications.

Vestibular syndrome

A clinical pattern classified through timing, triggers and associated findings before selection of the appropriate examination and differential.

Ostiomeatal complex

A region involved in drainage and ventilation of several anterior sinonasal compartments, interpreted with the actual individual anatomy.

Onodi cell

A posterior ethmoid anatomical variant with important potential relationships to the optic nerve and adjacent skull-base structures.

Nasoseptal flap

A vascularized reconstructive tissue option used in selected endonasal defects, with planning based on the actual pedicle, site and defect.

Glottic insufficiency

Inadequate glottic closure that can affect voice or airway protection, assessed with the relevant structural and functional examination.

Vocal-fold immobility

Reduced or absent movement that can arise through neural or mechanical mechanisms and does not alone prove one specific nerve injury.

Stroboscopy

An examination technique that can help assess aspects of vocal-fold vibration and mucosal-wave behavior under the relevant phonatory conditions.

Depth of invasion

A disease-specific pathological measurement contributing to certain primary-tumor staging frameworks, distinct from greatest surface dimension alone.

Extranodal extension

Tumor spread beyond the nodal capsule or boundary, interpreted within the actual primary-site staging and treatment framework.

Selective neck dissection

A neck operation preserving one or more lymph-node groups ordinarily removed in a classic comprehensive dissection, with actual levels specified.

Modified radical neck dissection

A comprehensive levels-I-through-V dissection preserving specified nonlymphatic structures, whose exact subtype depends on which structures remain.

Perineural invasion

Tumor involvement along a nerve-related pathway that can influence local assessment, treatment planning and the need for follow-up.

Thyroglossal tract

An embryological pathway relevant to certain midline neck cysts and their anatomical relationship with the hyoid and tongue base.

Septal hematoma

A collection associated with the nasal septum that can jeopardize cartilage and requires appropriate prompt recognition and management.

Reconstructive ladder

A framework for considering closure and tissue-replacement options without assuming that every defect must progress through an identical sequence.
