Chronic Pharyngitis01:23

Chronic Pharyngitis

Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

Summary
This summary is machine-generated.

Surgery for benign parotid tumors balances tumor removal with preserving facial function. Review shows various techniques offer low recurrence and minimal nerve damage, but optimal margins remain debated.

Area of Science:

  • Otolaryngology
  • Head and Neck Surgery
  • Surgical Oncology

Background:

  • Benign parotid tumors (BPTs) are common, necessitating surgical intervention.
  • Parotid surgery aims to balance complete tumor excision with preserving facial nerve function and aesthetic outcomes.
  • Less invasive surgical techniques for BPTs have emerged alongside traditional methods, with comparable recurrence rates.

Purpose of the Study:

  • To systematically review and compare surgical techniques for benign parotid tumors.
  • To summarize the advantages and disadvantages of available surgical approaches for BPTs.
  • To assess the current evidence regarding optimal surgical extent for BPTs.

Main Methods:

  • Systematic literature search in PubMed for studies on BPT surgery (January 2000 - January 2012).
  • Inclusion criteria: case series with clear surgical technique description and at least 10 patients.
  • Analysis of 37 selected case series from 463 initially identified articles.

Main Results:

  • Surgical techniques for BPTs are categorized into facial nerve dissecting (superficial, partial superficial, total parotidectomy) and non-nerve dissecting (extracapsular dissection) methods.
  • All techniques achieve low recurrence rates (<3%) and low permanent facial nerve morbidity (0.2-4%).
  • Key areas for positive margins include the tumor-facial nerve interface and pseudopodia.

Conclusions:

  • No consensus exists on the optimal surgical extent for achieving adequate margins in BPT surgery.
  • The tumor-nerve interface is a critical area for potential tumor spillage and positive margins.
  • Further long-term randomized clinical trials are needed to determine the ideal extent of excision in benign parotid surgery, with prolonged follow-up recommended.
