Abstract
Striated muscle insertions into the skin and mucosa are present in the head, neck, and pelvic floor. We reexamined the histology of these tissues to elucidate their role in transmission of the force. We examined histological sections of 25 human fetuses (gestational ages of ~11-19 weeks and ~26-40 weeks) and 6 cadavers of elderly individuals. Facial muscle insertion or terminal almost always formed as an interdigitation with another muscle or as a circular arrangement in which muscle fiber insertions were sandwiched and mechanically supported by other muscle fibers (like an in-series muscle). Our examination of the face revealed some limited exceptions in which muscle fibers that approached the dermis were always in the nasalis and mentalis muscles, and often in the levator labii superioris alaeque nasi muscle. The buccinator muscle was consistently inserted into the basement membrane of the oral mucosa. Parts of the uvulae muscle in the soft palate and of the intrinsic vertical muscle of the tongue were likely to direct toward the mucosa. In contrast, the pelvic floor did not contain striated muscle fibers that were directed toward the skin or mucosa. Although 'cutaneous muscle' is a common term, the actual insertion of a muscle into the skin or mucosa seemed to be very rare. Instead, superficial muscle insertion often consisted of interdigitated muscle bundles that had different functional vectors. In this case, the terminal of one muscle bundle was sandwiched and fixed mechanically by other bundles.

Laryngoscope 2023; 133:3520-3528. [PMID: 37551882 PMCID: PMC10843268 DOI: 10.1002/lary.30939] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2023] [Revised: 06/23/2023] [Accepted: 07/17/2023] [Indexed: 08/09/2023]
Abstract
OBJECTIVES To compare taste changes after transoral robotic surgery (TORS) to taste changes in healthy controls. METHODS Oropharyngeal cancer patients receiving TORS and healthy controls were recruited. Participants underwent posterolateral and whole-mouth psychophysical taste testing (identification, intensity, and hedonics) at baseline and at 2 weeks postoperatively (patients) or follow-up (controls). Surgeons reported suspension time and glossopharyngeal nerve injury (GNI) based on the identification and sacrifice of the nerve. A Clinical Global Impression (CGI) of taste symptoms was completed at each session ("My sense of taste bothers me" on a 5-point scale from Never [1] to Always [5]). A taste disorder (TD) was a CGI of 3 (Sometimes) or worse. Within-subject changes in CGI and psychophysical scores were computed. "Worsened taste" was a CGI increase by ≥1 point at follow-up. RESULTS Of 69 participants, most (33/37 tumor, 31/32 controls) had normal baseline taste (CGI < 3). 14/33 (42%) TORS patients and no controls developed new TDs at follow-up. More smokers (7/9) had worsened taste than nonsmokers (19/60, difference = 46% [95% CI 16%-76%]). More patients without GNI (6/22) than with GNI (0/15) had postoperative phantogeusia (difference = 27% [95% CI 9-45%]). Tumor-ipsilateral taste identification (TI) decreased more in patients (-11.3%) than controls (0.8%, difference = 12.2% [95% CI 5.0-19.3%]). Suspension time was not associated with worsened taste symptoms or psychophysical changes. CONCLUSIONS Patient-reported taste changes after TORS are frequent. Compared to healthy controls, TORS patients have decreased tumor-ipsilateral TI. Suspension time and GNI are unlikely to cause symptomatic TDs. Further investigations of the etiology and long-term symptom burden of TORS-associated TDs will aid in the management of oropharyngeal cancer patients.

Abstract
OBJECTIVE This study presents a novel classification of the anatomical subsites of the tonsillar fossa and discusses their associations with post-tonsillectomy hemorrhage (PTH) after extracapsular tonsillectomy. MATERIALS AND METHODS Coblation tonsillectomy was performed on three adult cadavers and the anatomical subsites of the tonsillar fossa based on the distribution of the tonsillar feeding artery: the upper pole (subsite A), most of the tonsil body (subsite B), the inferior tonsil body (subsite C), and components of the lower pole (subsites D and E). Extracapsular tonsillectomy was prospectively performed using various surgical techniques and PTH was evaluated. RESULTS A cadaveric study revealed that the intra- and extra-capsular vessel topographies were essentially identical. Although the demarcation lines varied either up or down by a few millimeters, the arterial vascular network was particularly dense at subsites D and E, and the vessel diameter at these subsites was significantly greater than at subsite C and also (especially) at subsite E. Of 680 patients who underwent tonsillectomy, PTH developed early in 13 (31.7%) and late in 28 (68.3%). Surgical interventions were required by 29/41 patients (70.7%). Subsites D and E were the most common subsites of late PTH and PTH that required intervention. Such intervention was rarely necessary when PTH developed at subsite A or B. CONCLUSIONS The new classification of the anatomical subsites of the tonsillar fossa aids inexperienced surgeons and provides an anatomical rationale for variation in surgical technique that minimizes vascular injury, thus improving safety.

Abstract
Deep molecular profiling of biological tissues is an indicator of health and disease. We used imaging mass cytometry (IMC) to acquire spatially resolved 20-plex protein data in tissue sections from normal and chronic tonsillitis cases. We present SpatialViz, a suite of algorithms to explore spatial relationships in multiplexed tissue images by visualizing and quantifying single-cell granularity and anatomical complexity in diverse multiplexed tissue imaging data. Single-cell and spatial maps confirmed that CD68+ cells were correlated with the enhanced Granzyme B expression and CD3+ cells exhibited enrichment of CD4+ phenotype in chronic tonsillitis. SpatialViz revealed morphological distributions of cellular organizations in distinct anatomical areas, spatially resolved single-cell associations across anatomical categories, and distance maps between the markers. Spatial topographic maps showed the unique organization of different tissue layers. The spatial reference framework generated network-based comparisons of multiplex data from healthy and diseased tonsils. SpatialViz is broadly applicable to multiplexed tissue biology.

Abstract
OBJECTIVES We aimed to provide information on the effects of tonsillectomy, in particular, its effects on taste dysfunction; also known as dysgeusia, and provide direction for future research in this area. METHODS We independently searched five databases (PubMed, SCOPUS, Embase, the Web of Science, and the Cochrane database) for related studies published as recently as December 2019. From the included studies, we reviewed the findings on tonsillectomy and taste disturbance through the use of a questionnaire, chemogustometry, and electrogustometry. We analyzed other conditions that were measured in these studies that included; postoperative pain intensity and other morbidities (eg, postoperative bleeding, hemostasis, tongue numbness and zinc, copper, and iron hemoglobin levels measured). RESULTS Postoperative taste disturbance based on questionnaire (VAS) scores at 14 days (SMD = -0.31 [-0.50, -0.12], P value = .0012) tended to decrease significantly in the post-tonsillectomy group compared to the pre-tonsillectomy group. Patients showed significantly decreased taste sensation after tonsillectomy than in the preoperative test. Postoperative electrogusmetry at 7 days (SMD = 0.60 [0.27, 0.94], P = .0004) tended to increase significantly in the post-tonsillectomy group compared to the pre-tonsillectomy group. CONCLUSION Tonsillectomy is a commonly performed surgery, and taste disturbance occurs frequently as a post operative effect. Taste dysfunction is important to patients with regard to their quality of life and the overall effects of taste on their day-to-day life. This study can be a useful meta-analysis of dysgeusia in tonsillectomy.

Abstract
OBJECTIVE To investigate risk factors for dysgeusia after tonsillectomy. METHODS A retrospective survey of medical records identified 318 patients (163 male and 155 female subjects aged 12-75 years, average 41.7±16.1 years) who underwent tonsillectomy. RESULTS Thirty three patients (10.4%) and seven patients (2.2%) reported suffering from dysgeusia three and six months after tonsillectomy, respectively. Average age, serum level of Zn and operation time were not significantly different between positive and negative findings of dysgeusia. Women with positive findings of dysgeusia (72.7%) was significantly higher than men (27.3%) (Odds ratio: 3.276, 95% CI: 1.441-7.450, p<0.005). A chi-square test of independence was calculated comparing the frequency of dysgeusia in under 60 years old group (13-59 years-old) and 60 years old and over group (60-75 years-old). A significant interaction was found (χ2 (1)=5.238. p<0.05). CONCLUSIONS Women and under 60 years old patients had a significantly higher rate of dysgeusia after tonsillectomy. It is recommended that patients are informed of the potential postoperative complication of dysgeusia.

Abstract
Parapharyngeal abscess (PPA) may cause life-threatening complications and peritonsillar abscess (PTA) and tonsillitis frequently precede PPA. The optimal management of PPA caused by PTA has been the subject of debate with respect to the surgical approach. We present three cases of PPA concomitant with PTA in elderly patients. In two cases, the abscesses in parapharyngeal space were drained by abscess tonsillectomy followed by intraoral incision of the tonsillar bed. On the other hand, the third case did not undergo abscess tonsillectomy because of his refusal of surgery and needed extraoral drainage after the aggravation of PPA. Based on the experience of those three cases, it was suggested that abscess tonsillectomy followed by intraoral incision of the tonsillar bed might be a useful surgical approach for the drainage of PPA concomitant with PTA, especially in elderly patients.

Abstract
Lingual branches of the glossopharyngeal nerve (CN Ⅸ) are at risk of injury during tonsillectomy due to their proximity to the muscle layer of the palatine tonsillar bed. However, it is unclear how often this common surgery leads to taste disturbances. We conducted a literature search using PubMed, Embase, Cochrane Library, Google Scholar, PsychInfo, and Ovid Medline to evaluate the available literature on post-tonsillectomy taste disorders. Studies denoting self-reported dysfunction, as well as those employing quantitative testing, i.e., chemogustometry and electrogustometry, were identified. Case reports were excluded. Of the 8 original articles that met our inclusion criteria, only 5 employed quantitative taste tests. The highest prevalence of self-reported taste disturbances occurred two weeks after surgery (32%). Two studies reported post-operative chemical gustometry scores consistent with hypogeusia. However, in the two studies that compared pre- and post-tonsillectomy test scores, one found no difference and the other found a significant difference only for the left rear of the tongue 14 days post-op. In the two studies that employed electrogustometry, elevated post-operative thresholds were noted, although only one compared pre- and post-operative thresholds. This study found no significant differences. No study employed a normal control group to assess the influences of repeated testing on the sensory measures. Overall, this review indicates that studies on post-tonsillectomy taste disorders are limited and ambiguous. Future research employing appropriate control groups and taste testing procedures are needed to define the prevalence, duration, and nature of post-tonsillectomy taste disorders.

Abstract
Oral sensations (i.e., taste, oral somatosensation, retronasal olfaction) are integrated into a composite sense of flavor, which guides dietary choices with long-term health impact. The nerves carrying this input are vulnerable to peripheral damage from multiple sources (e.g., otitis media, tonsillectomy, head injury), and this regional damage can boost sensations elsewhere in the mouth because of central interactions among nerve targets. Mutual inhibition governs this compensatory process, but individual differences lead to variation in whole-mouth outcomes: some individuals are unaffected, others experience severe loss, and some encounter sensory increases that may (if experienced early in life) elevate sweet-fat palatability and body mass. Phantom taste, touch, or pain sensations (e.g., burning mouth syndrome) may also occur, particularly in those expressing the most taste buds. To identify and treat these conditions effectively, emerging clinical tests measure regional vs. whole-mouth sensation, stimulated vs. phantom cues, and oral anatomy. Scaling methods allowing valid group comparisons have strongly aided these efforts. Overall, advances in measuring oral sensory function in health and disease show promise for understanding the varied clinical consequences of nerve damage.

Abstract
Objective With the emergence of transoral robotic approaches, head and neck surgeons are faced with an unfamiliar inside-out head and neck anatomy. This study was performed to describe key anatomic landmarks and surgical considerations of transoral robotic resection of the lateral oropharyngeal wall, the parapharyngeal space, and the base of the tongue. Study Design Descriptive transoral anatomic study. Setting Academic anatomy laboratory and tertiary academic hospital. Subjects and Methods Transoral dissections of the lateral pharyngeal wall, base of tongue, and parapharyngeal space were performed in 5 vascular silicone-injected cadavers to illustrate anatomic landmarks from the inside-out perspective. Lateral neck dissections were also performed to better appreciate the anatomic structures and to be more familiar with intraoperative anatomy. Results The neurovascular and muscular structures located in parapharyngeal space, lateral oropharyngeal wall, and base of tongue were described. Surgical significance of key anatomic landmarks was emphasized with high-quality illustrations. Conclusion A thorough understanding of transoral anatomy is crucial to perform transoral robotic surgery safely and efficiently. To understand inside-out anatomy of base of tongue, lateral oropharyngeal wall, and parapharyngeal space, cadaveric dissection is highly beneficial and may help to shorten the learning curve for transoral robotic dissections.

Abstract
The objective was to determine the incidence of exposure of the lingual branch of the glossopharyngeal nerve during tonsillectomy with a retrospective review of surgical findings in 138 children who underwent total tonsillectomy at a tertiary medical center. Age, sex, surgical indication, tonsil size, congenital abnormalities, operative time, and surgical findings indicating the presence or absence of the glossopharyngeal nerve in the tonsillar fossa were recorded. Statistical analysis was performed with z test, t test, and Fisher's exact test. Thirty-seven nerves were observed in 28 patients, with preponderance for the left fossa (24 of 37 vs 13 of 37; P = .01). In a comparison of children with and without exposed nerves, there was no statistically significant difference in mean age (6.89 vs 7.08; P = .84), proportion of males (14 of 28 vs 54 of 110; P = 1), or proportion of 3 to 4+ tonsils (20 of 28 vs 73 of 110; P = .66). In approximately 20% of children undergoing tonsillectomy, the lateral pharyngeal musculature incompletely protected the lingual branch of the glossopharyngeal nerve from the tonsil capsule.

Abstract
BACKGROUND Septoplasty, tonsillectomy (with and without adenoidectomy) and cervical lymph node excision are amongst the most common 50 inpatient operations in Germany. Intracapsular tonsillectomies (i.e. tonsillotomies) are increasingly performed. The aim of this study was to evaluate technical traps and pitfalls as well as alleged medical malpractice associated with tonsillectomy (TE), adenoidectomy (AE), tonsillotomy (TT), septoplasty (SP) and cervical lymph node excision (LN). METHODS A questionnaire was sent to the Regional Medical Conciliation Boards, Medical Services of the Health Insurance Companies (MDK) and Regional Institutes of Forensic Medicine in Germany to collect anonymized cases of complications following TE, TT, AE, LN and SP. The results were discussed in the light of the contemporary medical literature and published trials and verdicts in Germany. RESULTS The response rate of our survey was 55.9%. The Institutes of Forensic Medicine contributed nine cases, 49 cases were submitted by the Regional Conciliation Boards and none by MDK. All forensic cases were associated with exsanguinations following tonsillectomy including two children (5 and 8 years of age) and seven adults (aged 20 to 69 years). The fatal post-tonsillectomy hemorrhage (PTH) had occurred 8.7 days on average; four patients experienced the bleeding episode at home (day 5, 8, 9 and 17, respectively). Repeated episodes of bleeding requiring surgical intervention had occurred in 6 patients. Three Conciliation Boards submitted decicions associated with TT (1), AE (4), LN (3), SP (16) and TE (25). Cases with lethal outcome were not registered. Only three of the 49 cases were assessed as surgical malpractice (6.1%) including lesion of the spinal accessory nerve, wrong indication for TE and dental lesion after insertion of the mouth gag. The review of the medico legal literature yielded 71 published verdicts after AE and TE (29), LN (28) and SP (14) of which 37 resulted in compensation of malpractice after LN (16; 57%), TE (10; 37%), SP (8; 57%) and AE (2; 100%). There were 16 cases of PTH amongst 27 trials after TE resulting either in death (5) or apallic syndrome (5). Bleeding complications had occurred on the day of surgery in only 2 patients. 16 trials were based on malpractice claims following SP encompassing lack of informed consent (6), anosmia (4), septal perforation (2), frontobasal injury (2) and dry nose (2). Trials after LN procedures were associated exclusively with a lesion of the spinal accessory nerve (28), including lack of informed consent in 19 cases. 49 cases (69%) were decided for the defendant, 22 (31%) were decided for the plaintiff with monetary compensation in 7 of 29 AE/TE-trials, 9 of 28 LN-trials and 6 of 14 SP-trials. Lack of informed consent was not registered for AE/TE but LN (11) and SP (2). CONCLUSION Complicated cases following TE, TT, ATE, SP and LN are not systematically collected in Germany. It can be assumed, that not every complicated case is published in the medical literature or law journals and therefore not obtainable for scientific research. Alleged medical malpracice is proven for less than 6% before trial stage. Approximately half of all cases result in a plaintiff verdict or settlement at court. Proper documentation of a thourough counselling, examination, indication, informed consent and follow-up assists the surgeon in litigation. An adequate complication management of PTH is essential, including instructions for the patients/parents, instructions for the medical staff and readily available surgical instruments. Successful outcome of life-threatening PTH is widely based on a proper airway management in an interdisciplinary approach. Electrosurgical tonsillectomy techniques were repeatedly labeled as a risk factor for bleeding complications following TE. Institutions should analyse the individual PTH rate on a yearly basis. Contradictory expert opinions and verdicts of the courts concerning spinal accesory nerve lesions following LN are due to a lack of a surgical standard.

Abstract
We examined pharyngeal nerve courses in paraffin-embedded sagittal sections from 10 human fetuses, at 25-35 weeks of gestation, by using S100 protein immunohistochemical analysis. After diverging from the glossopharyngeal and vagus nerves at the level of the hyoid bone, the pharyngeal nerves entered the constrictor pharyngis medius muscle, then turned upward and ran superiorly and medially through the constrictor pharyngis superior muscle, to reach either the levator veli palatini muscle or the palatopharyngeus muscle. None of the nerves showed a tendency to run along the posterior surface of the pharyngeal muscles. Therefore, the pharyngeal nerve plexus in adults may become established by exposure of the fetal intramuscular nerves to the posterior aspect of the pharyngeal wall because of muscle degeneration and the subsequent rearrangement of the topographical relationship between the muscles that occurs after birth.

Abstract
CONCLUSION The lingual branches of the glossopharyngeal nerve were most likely to bring not only gustatory nerves to the postsulcal part of the tongue but also autonomic nerves to the small glands and vessels. Tonsillectomy may injure the ganglion or reduce its function due to scar formation after surgery. OBJECTIVES To determine the topographical anatomy of a suggested ganglion cluster along the lingual branches of the glossopharyngeal nerve and to identify the incidence. METHODS In the human pharynges of 12 donated cadavers, we studied the ganglia using routine procedures for paraffin-embedded histology and immunohistochemistry. RESULTS Near the palatine tonsil, the lingual branches of the glossopharyngeal nerve often contained ganglion cells (in 9 of 12 specimens). The ganglion cells, 20-40 µ in diameter, were sparsely distributed along a 0.5-3.0 mm length of the nerve course attached to the posterolateral aspect of the superior pharyngeal constrictor. Most of these cells were positive for neuronal nitric oxide synthase, while some were positive for tyrosine hydroxylase. Thus, the ganglion was composed of a mixed population of sympathetic and parasympathetic neurons.

Abstract
Otitis media and tonsillectomy are associated with enhanced palatability of energy dense foods and with weight gain. Otitis media can damage the chorda tympani nerve (CN VII); tonsillectomy and head and neck radiation treatment can damage the glossopharyngeal nerve (CN IX). Both of these nerves function prominently in taste sensation. The present study utilizes these sources of damage to study central interactions among the nerves that mediate oral sensations. Mild damage restricted to one of these nerves can actually intensify sensations evoked from undamaged nerves (i.e., whole-mouth taste, oral tactile sensations evoked by fats and irritants). These intensifications may result from disruption of central inhibitory taste circuits, as taste damage appears to disinhibit other oral sensory nerves. In addition, mild damage restricted to one taste nerve can intensify odors perceived from foods in the mouth during chewing and swallowing (i.e., retronasal olfaction); this may be a secondary consequence of the intensification of whole-mouth taste. Damage to both nerves leads to widespread oral sensory loss. At present, the link between sensory alterations and weight gain has not been established for adults (e.g., does increased fat preference occur in individuals with oral sensory intensifications, those with losses, or both?). Finally, pain in non-oral locations is also related to taste loss. When participants rated "the most intense pain of any kind they had ever experienced," those with the greatest taste loss gave the highest ratings. These effects suggest that taste loss significantly influences long-term health outcomes.

Abstract
STUDY OBJECTIVES To compare the components of the extracellular matrix in the lateral pharyngeal muscular wall in patients with and without obstructive sleep apnea (OSA). This may help to explain the origin of the increased collapsibility of the pharynx in patients with OSA. DESIGN Specimens from the superior pharyngeal constrictor muscle, obtained during pharyngeal surgeries, were evaluated using histochemical and immunohistochemical analyses to determine the fractional area of collagen types I and III, elastic fibers, versican, fibronectin, and matrix metalloproteinases 1 and 2 in the endomysium. SETTING Academic tertiary center. PATIENS: A total of 51 nonobese adult patients, divided into 38 patients with OSA and 13 nonsnoring control subjects without OSA. INTERVENTIONS Postintervention study performed on tissues from patients after elective surgery. MEASUREMENTS AND RESULTS Pharyngeal muscles of patients with OSA had significantly more collagen type I than pharyngeal muscles in control subjects. Collagen type I was correlated positively and independently with age. The other tested components of the extracellular matrix did not differ significantly between groups. In a logistic regression, an additive effect of both the increase of collagen type I and the increase in age with the presence of OSA was observed (odds ratio (OR), 2.06; 95% confidence interval (CI), 1.17-3.63), when compared with the effect of increased age alone (OR, 1.11; 95% CI, 1.03-1.20). CONCLUSION Collagen type I in the superior pharyngeal constrictor muscle was more prevalent in patients with OSA and also increased with age. It was hypothesized that this increase could delay contractile-relaxant responses in the superior pharyngeal constrictor muscle at the expiratory-inspiratory phase transition, thus increasing pharyngeal collapsibility.

Abstract
Transient post-tonsillectomy taste dysgeusia (PTD) is a common complaint. Long-lasting PTD is less frequent but has significant consequences on patients' quality of life, with some cases leading to medicolegal issues. Treatment options and knowledge about mechanisms and factors favoring PTD are limited. PTD may result from direct surgical injury, tongue compression, inflammatory processes or side effects of local anesthetics. Some authors also claim that dietary zinc deficiency plays a role in the development of PTD. Although this latter cause had not yet received a lot of attention, we report a case of a female patient who reported a 4-year PTD and recovered within 2 months after oral intake of zinc sulfate. This clinical observation, together with recent findings on significant improvement of taste disorders after zinc treatments for other causes, opens again the question of what extent zinc deficiency plays a role in PTD.

Abstract
Tonsillectomy is regarded as a safe procedure, with post-operative taste disturbances rarely reported. The aim of this study was to access taste function after tonsillectomy in a series of 60 patients. Sixty patients (age range 14-40 years; mean 24.4 years; median 21 years; STD 7.7 years), 24 males and 36 females, underwent bilateral tonsillectomy at the University Hospital of Patras, Greece. All patients were diagnosed with recurrent tonsillitis and randomly assigned to two groups. The first group consisted of 27 patients, who underwent tonsillectomy using scissors and raspatory with electrocautery for coagulation. The remaining 33 patients underwent tonsillectomy using pressure-assisted tissue-welding technology. Chemogustometry was used to evaluate the patients' taste function on the first postoperative day and succeedingly, 15 days and 1 month postoperatively. Three different quantities of tastant were used in each test. Taste recognition in posterior tongue regions proved to be more affected compared with anterior tongue regions in the first postoperative day. Bitter and sour tastes were more affected than those of sweet and salty. Succeeding tests yielded near normal results for all patients except two, with one patient achieving normal taste function 1 month postoperatively and the other still facing taste disorders 1 month after tonsillectomy. The results indicate that Tonsillectomy entails a temporary reduction in taste function. This finding should be attributed to direct or indirect intraoperative damage of the glossopharyngeal nerve or unintentional extension of the lingual nerve by application of the tongue retractor. No significant difference was noted between the two operative techniques evaluated in our study. In most cases taste function returns to preoperative levels within 2 weeks postoperatively. Post-tonsillectomy taste disturbances are uncommon, and patients should be informed of this possibility.

Abstract
OBJECTIVES To determine the frequency of altered tongue sensation following tonsillectomy, and its relationship to different surgical techniques. DESIGN Case-control study. SETTING District general hospital. PARTICIPANTS One hundred and four consecutive adults undergoing tonsillectomy, and 43 control patients. MAIN OUTCOME MEASURES Altered tongue sensation. RESULTS Twenty-eight of 100 patients described altered tongue sensation post-tonsillectomy. No patients in the control group experienced altered tongue sensation. There was a difference in rates of altered sensation between tonsillectomy patient groups undergoing bipolar diathermy and 'cold steel' techniques (p < 0.019). Three months after surgery, 22/23 contactable patients reported complete recovery of tongue sensation. One patient experienced tongue paraesthesia persisting until one year post-tonsillectomy. CONCLUSION Tonsillectomy resulted in altered tongue sensation in 28 per cent of our study group. Bipolar diathermy dissection was significantly more likely to cause altered sensation than cold steel dissection. Ninety-six per cent of these disturbances resolved by three months, all by one year. Possible alteration of tongue sensation should be discussed whilst obtaining consent for tonsillectomy.

Abstract
In an effort to clarify the morphologic characteristics of the palatopharyngeal muscle, we examined its origin, insertion, and positional relationship with other muscles. We found that the origin of the palatopharyngeal muscle was both the oral and the nasal side of the soft palate; it was also attached to both the palatal aponeurosis and the soft palate median. However, in some cases the muscle originated on the nasal side was lacked. When the palatopharyngeal muscle originated from both the oral and the nasal side, it traveled through its insertion via the levator muscle of the palatine velum. This insertion was seen in a wide area and could be divided into three parts: the pharynx anterior, central, and posterior walls. In the central pharyngeal wall, insertion into the pharyngeal aponeurosis, inferior constrictor pharyngeal muscle, and esophagus were observed. The present results suggest that the palatopharyngeal muscle has a close positional relationship with the levator and tensor muscles of the palatine velum, the pharyngeal constrictor muscles, and the esophagus.

Abstract
The stylopharyngeus plays a critical role in the clearance of the piriform recess. We dissected 78 sides of the pharynx from 55 donated cadavers and observed histology of another seven sides of the pharynx from seven cadavers. The stylopharyngeus consistently comprised (1) a descending muscle bundle surrounding the piriform recess and (2) an additional short sheet inserting into the tonsillar bed. Histologically, the former bundle connected to a thick fascia providing the lateral glossoepiglottic fold, extending along the submucosa of the piriform recess, and covering the thyroid cartilage, whereas the latter sheet intermingled with other pharyngeal wall muscles at and near the tonsillar bed. Notably, in 44.4% of female specimens, the additional sheet occupied a greater proportion in cross section than the descending muscle bundle. Given the different directions, the additional sheet seemed to check clearance function of the descending bundle for the piriform recess. Thus, particularly in women, interindividual differences in pharyngeal clearance were likely to depend on whether the additional sheet is strong or weak. Chin down in combination with tilting and rotating the head may represent effective exercises of the stylopharyngeus that could compensate for the disadvantages of additional insertion.

Abstract
AIMS Common complications of tonsillectomy are well recognized and are frequently explained to patients during the process of informed consent. This systematic review serves as a reminder of the unusual complications of this routine procedure. METHODS Studies were located using systematic searches in Medline, Embase, Cinahl, and the Cochrane Library electronic databases, together with hand searching of key texts, references, and reviews relevant to the field. Keywords used included the terms tonsillectomy, complications, unusual, and rare. References from the relevant articles were also searched for. INCLUSION CRITERIA The review was limited to English-language articles. Because of the low incidence of these complications, all cases were included regardless of age. EXCLUSION CRITERIA Complications of tonsillectomy in children with various syndromes were excluded. RESULTS Based on our criteria, 20 articles were identified. Only 10 articles were found suitable for review. All articles were either single case reports or small case series. Because of the small study cohort, the patients' ages ranged widely, from 3 to 21 years, with no sex dominance. The complications were categorized into intraoperative and immediate postoperative (<24 hours), intermediate (<2 weeks), and long-term (>2 weeks) unusual complications. Rare complications reviewed include intraoperative vascular injury, subcutaneous emphysema, mediastinitis, Eagle syndrome, atlantoaxial subluxation, cervical osteomyelitis, and taste disorders. CONCLUSIONS It is important that the otolaryngologist is aware that although the complications discussed are rare and interesting, they are associated with significant morbidity and mortality risks. Tonsillectomy, a very common ear, nose, and throat procedure, may not be so straightforward after all.

Abstract
OBJECTIVE To investigate the incidence of taste disturbance after tonsillectomy and laryngomicrosurgery. STUDY DESIGN A prospective study. METHODS Thirty-five consecutive patients underwent tonsillectomy with electric coagulator at Kanebo Memorial Hospital from September 2002 to May 2004. Another 35 consecutive patients underwent laryngomicrosurgery in a routine way during the same period. Both procedures were performed by two experienced doctors. The postoperative taste function was evaluated with questionnaire, electrogustometry (EGM), and serum levels of Zn, Cu and Fe. RESULTS After tonsillectomy, 3/35 patients (8.6%) complained of taste disturbance, due to the pressure on the tongue in two, and Zn deficiency after lack of intake in one. All three patients recovered taste within 1.5 months. None of our patients had taste disturbance due to surgical insult of the lingual branch of the glossopharyngeal nerve. After laryngomicrosurgery, only one patient (2.9%) complained of taste disturbance with elevation of the EGM threshold that resulted from the pressure on the tongue. In addition, abnormal sensation in the tongue occurred in 9 cases (25.7%) after tonsillectomy and in 2 cases (5.7%) after laryngomicrosurgery, and feeling of thirst occurred in 12 cases (34.3%) and in 8 cases (22.9%), respectively. CONCLUSION Taste disturbance occurs in few cases when experienced surgeons perform tonsillectomy or laryngomicrosurgery. However, it is recommended to inform the patients of the potential postoperative complications such as taste disturbance and abnormal sensation of the tongue.

Abstract
OBJECTIVE To introduce a modified infiltration technique of anesthetic mixture in order to reduce post-tonsillectomy pain based on histo-anatomic observations and tonsil's innervation detection. DESIGN Histo-anatomic, expanded case report. SETTING Tertiary care facility in Beirut, Lebanon. PATIENTS One hundred and seven patients who underwent tonsillectomy allocated in three groups. INTERVENTIONS Histo-anatomic observations were studied in 62 patients (group I). Nerve-stimulator detection was performed in group II (20 children). An expanded case report of 25 children (group III) was conducted using a modified infiltration technique based on the findings of the histo-anatomic observations and nerve detection. OUTCOME MEASURES Post-operative pain at 0, 6, 12h and once daily for the 10-day follow-up period, hemodynamic stability, hospital stay, patient satisfaction and analgesics consumption were assessed. RESULTS The nerve-stimulator confirmed the histo-anatomic findings by strong contractions of the superior constrictor muscle, soft palate and uvula when the needle is mainly in the middle part of the peritonsillar area where the glossopharyngeal nerve branches predominate. No visual analogue scale median exceeded 1 for any child at any predetermined time interval, only three children (12%) required opoiods during the follow-up period. All children (100%) were discharged the same day, only 4% of parents were unsatisfied. Hemodynamic stability was maintained during pre- and post-operation. CONCLUSION This modified technique with minimal volume of anesthetic mixture seems to reduce post-operative pain in tonsillectomy patients; a randomized double-blinded prospective study was designed based on the findings in this initial series of children.

Abstract
OBJECTIVE/HYPOTHESIS Tonsillectomy is among the most commonly performed procedures. As with any surgery, head and neck surgeons must be aware of possible complications and their potential affects. At our smell and taste center, we have been referred several patients in a 6-month period with the complaint of taste distortion after tonsillectomy. We report in this article a patient that complains of taste distortion after a right tonsillectomy for unilateral tonsillar hypertrophy. STUDY DESIGN A prospective study documenting taste distortion after tonsillectomy using clinical, subjective, and objective evaluation. METHODS The clinical course of a patient with taste distortion after a tonsillectomy is described. The gustatory function was investigated by conducting electrogustometry and spatial taste testing. Threshold measurements were determined at three left- and three right-side tongue regions: 1) the tongue tip region (innervated by the chorda tympani branch of the facial nerve), 2) the lateral margin of the tongue (anterior to the foliate papillae), and 3) the posterior tongue region (innervated by the lingual branch of the glossopharyngeal nerve). RESULTS After a complete clinical evaluation and taste testing, it was found that the patient suffered an injury to the right lingual branch of the glossopharyngeal nerve. The close anatomic relationship between the palatine tonsil and lingual branch of the glossopharyngeal nerve makes the nerve vulnerable during tonsillectomy. This injury has caused the patient to suffer ageusia to the right posterior one third of the tongue, compensated by a contralateral phantogeusia (phantom taste) with clinical dysgeusia. The phantogeusia was abolished by application of anesthetic to the area where the phantom was perceived. We propose that the phantogeusia is the result of release-of-inhibition in the contralateral glossopharyngeal nerve. CONCLUSION Taste distortion (including, phantogeusia and dysgeusia) after tonsillectomy is rarely reported as a complication but has a significant impact on quality of life. This article examines the taste distortion presence as a complication after tonsillectomy to make head and neck surgeons aware of this serious complication and the pathophysiology of taste distortion.
