Article Abstract

The realization of customized earing plugs and earmolds for hearing aids requires an impression of the external auditory canal to obtain a siliconized mold. Silicone used for ear impressions is known to be safe and inert but deposition of silicone in the middle ear can middle and inner ear damages. We present a case of accidental injection of silicone in the middle ear and the Eustachian tube resulting in an erosion of the carotid canal. Laryngoscope, 133:3358-3360, 2023.

Patulous Eustachian Tube (PET) dysfunction is a rare condition characterized by an abnormally open Eustachian tube, leading to symptoms such as autophony, auditory fullness, and pulsatile tinnitus. This case report describes a 48-year-old female weighing 72.4 kilograms who developed persistent autophony and hearing her own breathing and heartbeat sounds following significant weight loss after sleeve gastrectomy.

Background: Cleft palate repair aims to achieve tension-free closure without compromising Eustachian tube function and hearing outcomes. The effect of pterygoid hamulotomy on postoperative hearing remains inconclusive.

Purpose: This study evaluated the effect of pterygoid hamulotomy during palatoplasty on hearing thresholds and middle ear status in nonsyndromic cleft palate patients.

Background: Alternobaric facial palsy (AFP) is a rare peripheral facial nerve palsy resulting from transient neurapraxia when sudden ambient-pressure changes disrupt middle-ear equilibrium. Common precipitants include scuba diving, air travel, and altitude. AFP triggered by routine activities is exceedingly uncommon.

Objective: Sacrifice of pterygopalatine fossa (PPF) neurovascular structures during endoscopic endonasal transpterygoid approach (EETPA) may impact a patient's comorbidity. We present anatomical and surgical techniques for maximizing PPF transposition while preserving its neurovascular structures through orbito-pterygo-sphenoidal (OPS) ligament release and descending palatine canal (DPC) decompression.

Methods: The EETPA was performed on six specimens.

Chronic nasopharyngeal and otic disorders in children represent a significant clinical challenge due to their multifactorial etiology, variable presentation, and frequent resistance to standard therapies. Although often approached from a symptomatic or anatomical perspective, these conditions are deeply rooted in histological and molecular alterations that sustain inflammation, impair mucosal function, and promote recurrence. This narrative review synthesizes the current knowledge on the normal histology of the nasopharynx, Eustachian tube, and middle ear, and explores key pathophysiological mechanisms, including epithelial remodeling, immune cell infiltration, cytokine imbalance, and tissue fibrosis.
